Frequently Asked Questions (FAQ)

Q: Can the HLMP-LB71-TUBDD directly replace the QLMP-LB80-UVBDD in existing designs?

A: The HLMP-LB71-TUBDD is the manufacturer-recommended substitute and shares the same color, wavelength range, and through-hole mounting configuration. Circuit-level compatibility depends on verification of forward voltage (3.1V typical for the substitute) and current requirements (20mA test current) against the original design specifications.

Q: What is the primary difference between these two parts?

A: The QLMP-LB80-UVBDD is obsolete, while the HLMP-LB71-TUBDD is an active product. The substitute features a diffused lens and specified electrical parameters (3.1V forward voltage, 470nm dominant wavelength), whereas the original part specifications are not fully detailed in available documentation.

Q: Are there packaging considerations for this substitution?

A: The HLMP-LB71-TUBDD is supplied in Tape & Box (TB) packaging. Both parts use through-hole radial mounting, making them mechanically compatible in standard PCB layouts designed for 4mm LED components.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the QLMP-LB80-UVBDD and HLMP-LB71-TUBDD are REACH Unaffected and classified as EAR99 for export control purposes. The substitute additionally meets ROHS3 compliance standards.
