Engineering Selection Recommendations
Tier 1 - Direct Mechanical & Electrical Equivalents:
HLMP-3507-D00B2 is the primary substitute. It maintains right-angle through-hole mounting, operates within the acceptable voltage range (2.1V vs. 1.9V), and delivers comparable brightness (4.2mcd vs. 2.3mcd). Both parts are ROHS3 compliant with MSL 1 rating. The forward voltage increase of 0.2V requires circuit resistor recalculation but does not affect functional compatibility in typical indicator applications.
Tier 2 - Compatible Alternatives (Voltage-Dependent):
HLMP-3507 and HLMP-3507-D0001 are active Broadcom parts with identical optical and electrical characteristics to HLMP-3507-D00B2, differing only in packaging (Bulk vs. Tape & Reel). These are suitable for designs operating at 2.1V forward voltage.
HLMP-3680 operates at 5V forward voltage and is appropriate only for circuits designed for higher voltage operation. The reduced brightness (1.6mcd) may require circuit evaluation.
Tier 3 - Cross-Manufacturer Alternatives:
151051VS04000 (Würth Elektronik) operates at 2.1V with significantly higher brightness (140mcd) and higher test current (20mA). This part is suitable only for applications where increased brightness is acceptable and circuit current capacity permits.
4302H5-5V (Visual Communications Company) operates at 5V and is compatible only with 5V circuit designs. The 8mcd brightness and 60° viewing angle provide adequate performance for standard indicator applications.
All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring environmental and moisture handling compatibility with the original specification.
Frequently Asked Questions (FAQ)
Q: Can HLMP-3507-D00B2 directly replace HLMP47409MP6 without circuit modification?
A: HLMP-3507-D00B2 is mechanically and functionally compatible. The forward voltage difference (2.1V vs. 1.9V) requires recalculation of series resistor values to maintain correct operating current. No other circuit modifications are necessary.
Q: What is the difference between HLMP-3507, HLMP-3507-D0001, and HLMP-3507-D0002?
A: These parts are electrically and optically identical. The differences are packaging only: HLMP-3507 is supplied in Bulk, HLMP-3507-D0001 in Tape & Reel (TR), and HLMP-3507-D0002 in Cut Tape (CT). Select based on procurement and assembly requirements.
Q: Why does 151051VS04000 have significantly higher brightness (140mcd)?
A: The Würth Elektronik part operates at a higher test current (20mA vs. 2mA-10mA). Higher current produces greater light output. This part is suitable only if circuit design accommodates the increased current draw and brightness is acceptable for the application.
Q: Can I use 4302H5-5V or HLMP-3680 in a 2V circuit?
A: No. Both parts are rated for 5V forward voltage operation. Using them in a 2V circuit will result in insufficient current and no illumination. These parts are suitable only for 5V circuit designs.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the environmental and moisture specifications of the original HLMP47409MP6.
Q: What is the viewing angle difference between the original part and substitutes?
A: HLMP47409MP6 has a 50° viewing angle. Most substitutes (HLMP-3507 series, 4302H5-5V) provide 60° viewing angle, offering a wider light distribution. 151051VS04000 provides 40° viewing angle, which is narrower. Select based on application requirements for light distribution.
Q: Is the right-angle mounting feature available in all substitutes?
A: No. Only HLMP-3507-D00B2 and HLMP-3507-D00B1 explicitly specify right-angle through-hole mounting. Standard HLMP-3507 variants and cross-manufacturer parts use radial through-hole mounting. Verify mechanical fit requirements before selection.
