HLMP2550 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The HLMP2550 is an active green LED circuit board indicator manufactured by Everlight Electronics Co Ltd, designed for through-hole mounting applications. This single green LED operates at 2.2V with a 90mA current rating and delivers 50 millicandela output at a peak wavelength of 565nm. The component features a rectangle with flat top lens style and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Finding equivalent and substitute parts becomes necessary when managing inventory across multiple suppliers, addressing component obsolescence, or optimizing procurement strategies while maintaining functional compatibility within circuit board indicator applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the HLMP2550 is determined by the following critical parameters:

Matching Parameters (Required for Direct Substitution):

• Color: Green
• Wavelength - Peak: 565nm
• Voltage Rating: 2.2V
• Mounting Type: Through Hole
• Lens Style: Rectangle with Flat Top
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Variable Parameters (Acceptable Differences):

• Current Rating: The HLMP2550 operates at 90mA. Substitute parts may operate at different current ratings (such as 30mA) provided the circuit design accommodates the alternative current specification.
• Configuration: The main part uses Single configuration. Substitute parts may use alternative configurations (such as Bar - Single, SIP) if mechanical and electrical integration is compatible.
• Lens Size: The main part does not specify lens dimensions. Substitute parts with defined lens sizes (19.05mm x 3.81mm) remain compatible if physical space permits.

The HLMP-2550 from Broadcom Limited qualifies as a substitute based on matching color, wavelength, voltage, mounting type, lens style, and compliance certifications, despite differences in current rating and configuration type.

Parameter Comparison

Engineering Selection Recommendations

Both the HLMP2550 (Everlight Electronics Co Ltd) and HLMP-2550 (Broadcom Limited) are active products with ROHS3 compliance and MSL 1 (Unlimited) ratings, confirming their suitability for current production and long-term availability.

Selection Criteria Based on Provided Data:

The HLMP2550 maintains a 90mA current specification, appropriate for applications requiring higher brightness output or where circuit design accommodates this current draw. The HLMP-2550 operates at 30mA, suitable for applications with lower power budgets or where reduced current consumption is advantageous.

Both parts deliver identical 50 millicandela output at 565nm peak wavelength with 2.2V forward voltage, ensuring consistent optical performance in circuit board indicator applications. The rectangle with flat top lens style and through-hole mounting are identical across both parts.

Substitution between these parts is valid when circuit design parameters (current limiting resistor values, power supply capacity, and PCB layout) are adjusted to accommodate the 30mA versus 90mA difference. Compliance certifications and moisture sensitivity ratings are equivalent, eliminating environmental or regulatory concerns in the substitution decision.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-2550 (Broadcom) directly replace the HLMP2550 (Everlight) without circuit modification?

A: Direct replacement without modification is not recommended. The HLMP-2550 operates at 30mA compared to the HLMP2550's 90mA rating. Circuit current-limiting resistor values must be recalculated to accommodate the lower current specification. Failure to adjust resistor values will result in incorrect LED brightness and potential component damage.

Q: Are the optical characteristics identical between these two parts?

A: Yes. Both parts deliver 50 millicandela output at 565nm peak wavelength with 2.2V forward voltage. Optical performance in circuit board indicator applications is equivalent.

Q: What is the significance of the configuration difference (Single versus Bar - Single, SIP)?

A: Configuration describes the LED package structure. The HLMP2550 uses a Single configuration, while the HLMP-2550 uses a Bar - Single, SIP configuration. This difference affects physical package dimensions and PCB footprint. Verify that the substitute part's physical dimensions and pin configuration are compatible with the existing PCB layout before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the HLMP2550 and HLMP-2550 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. Compliance certifications are equivalent, and both parts are suitable for production environments with identical regulatory requirements.

Q: What inventory considerations apply to these substitute parts?

A: The HLMP2550 has 876 pieces in stock, while the HLMP-2550 has 1443 pieces available. Substitute part selection may be influenced by inventory availability and procurement lead times when component sourcing is a consideration.

Q: Are there any electrical parameter restrictions that would prevent substitution?

A: The primary electrical difference is the current rating (90mA versus 30mA). This difference requires circuit design adjustment but does not prevent substitution. Voltage rating (2.2V), wavelength (565nm), and brightness (50mcd) are identical, confirming electrical compatibility at the optical output level.
