Key Parameters

Substitute Part Grouping Explanation

Substitute parts are organized into two functional categories based on electrical and mechanical compatibility with the HLMP6505AYR:

Category 1: Surface Mount SMD Yoke Bend Configuration (Direct Mechanical Substitutes)

These parts maintain identical mounting type (Surface Mount) and lead configuration (2-SMD, Yoke Bend), enabling direct PCB layout compatibility. Substitution is determined by matching forward voltage (2V to 2.1V range), test current (10mA), wavelength peak (565nm), and maximum height (2.92mm or lower). Parts in this category include HLMP-6505-L0021 and HLMP-6505-L0031, which differ in lens size and height specifications but maintain functional equivalence for green LED indication circuits.

Category 2: Through Hole Axial Configuration (Functional Equivalents with Different Mounting)

These parts provide electrical and optical equivalence but require different PCB layout and assembly processes due to axial through-hole mounting. Substitution applies when forward voltage tolerance (2.1V to 5V range), wavelength (565-569nm), and color (green) match application requirements. Parts HLMP-6500, HLMP-6505 (Broadcom), HLMP-6800, and HLMP-6820 fall into this category, with variations in millicandela rating (2mcd to 40mcd) and viewing angle (28° to 90°) based on specific circuit design needs.

Key Parameters Determining Substitution:

• Forward voltage (Vf) within 2V to 2.1V range for low-voltage applications; 5V for higher-voltage circuits
• Wavelength peak at 565nm or dominant wavelength 569nm for green spectrum consistency
• Test current at 10mA standard
• Lens transparency (clear or diffused) based on application visibility requirements
• Mounting type compatibility (Surface Mount SMD vs. Through Hole Axial)
• Maximum height constraint (2.44mm to 2.92mm)
• RoHS3 compliance and MSL rating for supply chain and storage requirements

Parameter Comparison

Engineering Selection Recommendations

For Direct Surface Mount SMD Replacement (Same PCB Layout):

HLMP-6505-L0021 and HLMP-6505-L0031 are qualified substitutes when PCB layout and assembly process must remain unchanged. Both parts maintain 2-SMD yoke bend configuration with maximum height of 2.92mm or 2.44mm respectively. Forward voltage increases from 2V to 2.1V, requiring circuit resistor recalculation for constant current operation. Millicandela rating increases to 40mcd, providing enhanced brightness for the same 10mA test current. Viewing angle widens from 25° to 28°, affecting light distribution characteristics. Both parts carry ROHS3 compliance and MSL 2A rating, requiring controlled storage conditions (4 weeks at 30°C/60% RH) compared to the main part's unlimited shelf life.

For Through Hole Axial Configuration (PCB Redesign Required):

HLMP-6505 (Broadcom axial version) provides electrical equivalence with identical 2.1V forward voltage and 40mcd brightness, enabling direct functional replacement in through-hole designs. HLMP-6500 offers reduced brightness (7mcd) with 2.1V forward voltage and 90° viewing angle for wide-angle indication applications. HLMP-6800 and HLMP-6820 operate at 5V forward voltage with diffused lens transparency, suitable for higher-voltage circuits requiring reduced brightness (5mcd and 2mcd respectively) and omnidirectional light distribution (90° viewing angle).

Compliance and Supply Chain Considerations:

All substitute parts maintain ROHS3 compliance, meeting environmental and regulatory requirements. The main part HLMP6505AYR provides superior moisture handling with MSL Level 1 (unlimited shelf life), while all Broadcom substitutes require MSL 2A storage conditions. For applications with extended inventory holding periods or high-humidity environments, the main part's MSL rating provides operational advantage. All parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q1: Can HLMP-6505-L0021 replace HLMP6505AYR in existing PCB designs without layout modifications?

A: Yes. Both parts use identical 2-SMD yoke bend surface mount configuration with matching maximum height (2.92mm). PCB footprint and assembly process remain unchanged. However, forward voltage increases from 2V to 2.1V, requiring resistor value adjustment in current-limiting circuits to maintain constant LED current. Brightness increases from 12mcd to 40mcd, and viewing angle widens from 25° to 28°, which may affect optical performance in space-constrained applications.

Q2: What is the primary difference between HLMP-6505-L0031 and HLMP-6505-L0021?

A: Both parts share identical electrical specifications (2.1V forward voltage, 40mcd brightness, 28° viewing angle, 565nm peak wavelength). The key difference is lead configuration: HLMP-6505-L0021 uses yoke bend leads, while HLMP-6505-L0031 uses Z-bend leads with bottom entry mounting. HLMP-6505-L0031 also provides reduced maximum height (2.44mm vs. 2.92mm), enabling use in space-constrained PCB designs. Z-bend configuration requires different PCB pad layout compared to yoke bend.

Q3: When should through-hole axial parts (HLMP-6505, HLMP-6500, HLMP-6800, HLMP-6820) be selected over SMD alternatives?

A: Through-hole axial parts are selected when PCB design uses through-hole assembly technology or when existing designs require axial lead configuration. HLMP-6505 (Broadcom axial) provides direct electrical equivalence to the main part with 2.1V forward voltage and 40mcd brightness. HLMP-6500 reduces brightness to 7mcd with 90° wide-angle viewing for omnidirectional indication. HLMP-6800 and HLMP-6820 operate at 5V forward voltage for higher-voltage circuits, with 5mcd and 2mcd brightness respectively.

Q4: What is the impact of forward voltage difference between HLMP6505AYR (2V) and Broadcom substitutes (2.1V)?

A: The 0.1V increase requires circuit resistor recalculation to maintain constant LED current. In a typical current-limiting circuit, resistor value must increase proportionally to compensate for higher forward voltage drop. For example, in a 5V supply circuit with 10mA target current: original resistor = (5V - 2V) / 10mA = 300Ω; new resistor = (5V - 2.1V) / 10mA = 290Ω. This adjustment ensures consistent LED brightness and prevents overcurrent conditions.

Q5: How do lens transparency differences (clear vs. diffused) affect application suitability?

A: Clear lens (HLMP6505AYR, HLMP-6505-L0021, HLMP-6505-L0031) provides focused light output with narrow viewing angle (25° to 28°), suitable for direct line-of-sight indication. Diffused lens (HLMP-6500, HLMP-6800, HLMP-6820) scatters light across 90° viewing angle, enabling omnidirectional visibility from multiple angles. Diffused parts reduce brightness perception due to light spreading, requiring higher millicandela rating for equivalent perceived brightness. Selection depends on application geometry and viewing requirements.

Q6: What are the storage and handling differences between HLMP6505AYR (MSL 1) and Broadcom substitutes (MSL 2A)?

A: HLMP6505AYR carries MSL Level 1 rating, permitting unlimited shelf life under standard storage conditions (≤30°C, ≤60% RH). Broadcom substitutes carry MSL 2A rating, limiting shelf life to 4 weeks under identical conditions. After 4 weeks, MSL 2A parts require baking at 125°C for 24 hours before use to remove absorbed moisture. For high-volume production with extended inventory holding, the main part's MSL 1 rating reduces moisture-related defect risk and eliminates baking requirements.

Q7: Are all substitute parts RoHS3 compliant?

A: Yes. HLMP6505AYR and all listed substitute parts (HLMP-6505-L0021, HLMP-6505-L0031, HLMP-6505, HLMP-6500, HLMP-6800, HLMP-6820) carry ROHS3 compliance certification. All parts meet EU Directive 2011/65/EU requirements for restricted hazardous substances. ECCN classification (EAR99) and HTSUS code (8541.41.0000) are identical across all parts, ensuring consistent export compliance and tariff treatment.

Q8: Can HLMP-6800 or HLMP-6820 (5V parts) substitute for HLMP6505AYR (2V part) in the same circuit?

A: No. HLMP-6800 and HLMP-6820 operate at 5V forward voltage, requiring complete circuit redesign. These parts are suitable only for applications designed for 5V LED operation. Direct substitution in 2V circuits would result in LED failure due to insufficient forward voltage. However, in new designs targeting 5V supply voltage, HLMP-6800 (5mcd) and HLMP-6820 (2mcd) provide green LED indication with diffused lens and 90° viewing angle.

Q9: What inventory considerations apply when selecting between main part and substitutes?

A: HLMP6505AYR (Everlight) maintains 1,110 pcs in stock. Broadcom substitutes offer significantly higher availability: HLMP-6505 (960,200 pcs), HLMP-6505-L0021 (2,400 pcs), HLMP-6505-L0031 (1,780 pcs), HLMP-6500 (47,198 pcs), HLMP-6800 (8,969 pcs), HLMP-6820 (2,200 pcs). For high-volume production or long-term supply security, Broadcom parts provide superior inventory depth. For applications requiring specific MSL 1 rating or Everlight manufacturer specification, the main part remains the only qualified option despite lower stock levels.

Q10: Which substitute part provides the closest optical and electrical match to HLMP6505AYR?

A: HLMP-6505-L0021 provides the closest match with identical 2-SMD yoke bend surface mount configuration, matching maximum height (2.92mm), and equivalent wavelength (565nm peak). Forward voltage increases marginally from 2V to 2.1V, and brightness increases from 12mcd to 40mcd. Viewing angle widens from 25° to 28°. The primary trade-off is MSL rating reduction from Level 1 to Level 2A, requiring controlled storage conditions. For applications where brightness increase and slightly wider viewing angle are acceptable, HLMP-6505-L0021 provides direct PCB compatibility with minimal circuit modification.
