Substitute Part Grouping Explanation

Substitute parts for the HLMP3316A4R0 are classified into three categories based on electrical and mechanical compatibility:

Direct Manufacturer Substitutes (Everlight Electronics): EALP05RDDRA5 and EALP05RDDRA6 share identical mechanical form factors (5mm T-1 3/4 through-hole radial package, 8.90mm maximum height) and similar forward voltage (2V vs. 2.2V). These parts are active products with higher brightness ratings (200mcd vs. 35mcd) and operate at 20mA test current. The wavelength specifications (624nm dominant, 632nm peak) fall within the red spectrum range of the original part (635nm peak).

Parametric Equivalent (onsemi): HLMP3316 from onsemi provides identical electrical characteristics (2.2V forward voltage, 10mA test current, 35mcd brightness, 35° viewing angle, 635nm peak wavelength) and mechanical specifications (T-1 3/4 package, 8.89mm height). This part is also obsolete but represents a direct parametric match from an alternative manufacturer.

Similar Substitutes (VCC and Dialight): Parts 4302H1-5V, 4302H1-12V, 5219246F, and 5219320F share the same red diffused lens color, T-1 3/4 through-hole mounting, and radial package configuration. These parts differ in forward voltage ratings (ranging from 1.8V to 12V), brightness levels (2mcd to 8mcd), and viewing angles (50° to 60°). These are active products suitable for applications where the specific electrical characteristics can be accommodated by circuit design.

Key Parameters Determining Substitution:

• Lens color and transparency (red diffused)
• Package type and mounting (T-1 3/4 through-hole radial)
• Physical dimensions (approximately 5mm diameter, 8.89-10.08mm height)
• Forward voltage range (1.8V to 12V depending on application requirements)
• Wavelength spectrum (630-635nm peak)
• RoHS3 compliance and MSL rating

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Minimum Circuit Modification):

HLMP3316 from onsemi provides the closest parametric match with identical forward voltage (2.2V), test current (10mA), brightness (35mcd), and viewing angle (35°). This part is suitable for direct substitution in existing circuit designs without modification. Although classified as obsolete, it maintains full compatibility with the original HLMP3316A4R0 specifications.

For Active Product Substitution (Preferred for New Designs):

EALP05RDDRA5 and EALP05RDDRA6 from Everlight are active products with identical mechanical form factors and similar electrical characteristics. The forward voltage difference (2V vs. 2.2V) is within typical LED tolerance ranges. The higher brightness rating (200mcd vs. 35mcd) requires circuit current limiting adjustment from 10mA to 20mA test current. These parts are recommended for new production designs requiring long-term component availability.

For Voltage-Specific Applications:

4302H1-5V and 4302H1-12V from VCC are active products designed for specific voltage supply rails. Selection depends on circuit supply voltage: 4302H1-5V for 5V systems, 4302H1-12V for 12V systems. These parts feature wider viewing angles (60°) and lower brightness (8mcd), suitable for applications where brightness reduction and wider light distribution are acceptable trade-offs.

5219246F from Dialight maintains the original 2.2V forward voltage and 10mA test current with slightly reduced brightness (7mcd vs. 35mcd). 5219320F operates at 1.8V with minimal current draw (2mA), suitable for low-power indicator applications.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring compatibility with modern manufacturing and environmental standards. All parts are classified under HTSUS 8541.41.0000 and ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can EALP05RDDRA5 directly replace HLMP3316A4R0 without circuit modification?

A: EALP05RDDRA5 shares identical mechanical specifications and similar forward voltage (2V vs. 2.2V). However, the test current differs (20mA vs. 10mA) and brightness is significantly higher (200mcd vs. 35mcd). Circuit current limiting resistors must be recalculated for the 20mA operating point. The mechanical form factor allows direct PCB mounting without layout changes.

Q: What is the difference between EALP05RDDRA5 and EALP05RDDRA6?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: EALP05RDDRA5 is supplied in standard packaging, while EALP05RDDRA6 is supplied in Tape & Box (TB) format. Selection depends on production volume and assembly equipment compatibility.

Q: Why do 4302H1-5V and 4302H1-12V have different forward voltages?

A: These parts are designed as integrated indicator solutions with built-in current limiting for specific supply voltages. The 5V version operates at 5V forward voltage with 10mA test current, while the 12V version operates at 12V with 13mA test current. These are not standard LEDs but rather complete indicator assemblies optimized for direct connection to power supplies.

Q: Can I use 5219320F as a direct replacement for lower power applications?

A: 5219320F operates at 1.8V forward voltage with only 2mA test current, making it suitable for ultra-low-power indicator applications. The brightness is significantly reduced (2mcd vs. 35mcd). This part is appropriate only if the application can tolerate reduced light output and operates from lower voltage supplies.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts are RoHS3 compliant. The original HLMP3316A4R0 is also RoHS3 compliant. All parts maintain MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: What is the viewing angle significance when selecting a substitute?

A: Viewing angle determines the light distribution pattern. The original HLMP3316A4R0 has a 35° viewing angle, providing focused light output. Substitute parts with wider viewing angles (50-60°) distribute light over a broader area, suitable for applications requiring visibility from multiple angles. Narrower viewing angles (30°) concentrate light for direct-view applications.

Q: Can HLMP3316 from onsemi be used in new production designs?

A: HLMP3316 is classified as obsolete, indicating discontinued manufacturing. While parametrically identical to HLMP3316A4R0, using obsolete parts in new designs creates long-term supply chain risk. For new production, EALP05RDDRA5 or EALP05RDDRA6 from Everlight are recommended as active alternatives with identical mechanical compatibility.

Q: What are the inventory considerations for these substitute parts?

A: Current inventory levels are: HLMP3316A4R0 (885 pcs), EALP05RDDRA5 (1081 pcs), EALP05RDDRA6 (950 pcs), HLMP3316 (986 pcs), 4302H1-5V (2640 pcs), 4302H1-12V (1927 pcs), 5219246F (3872 pcs), 5219320F (2604 pcs). Active products (Everlight EALP series, VCC 4302H1 series, Dialight 521 series) generally maintain higher inventory levels than obsolete parts.
