Frequently Asked Questions (FAQ)

Q: Can the HLMP-LB71-TUBDD directly replace the QLMP-LB84-UVPDD in existing designs?

A: Yes. Both components are manufactured by Broadcom Limited, share the same application class (LED indication - discrete), and maintain identical regulatory compliance (REACH Unaffected, EAR99). The substitute offers active product status compared to the obsolete original part.

Q: What are the key mechanical compatibility factors?

A: Both parts utilize 4mm form factor packages with through-hole mounting configuration. The HLMP-LB71-TUBDD is specified as a 4mm oval package with radial mounting type, suitable for standard PCB through-hole assembly processes.

Q: Are there compliance differences between the two parts?

A: The HLMP-LB71-TUBDD provides ROHS3 compliance certification, while the original part does not specify this status. Both maintain REACH Unaffected classification and EAR99 export control designation.

Q: What is the moisture sensitivity level difference?

A: The QLMP-LB84-UVPDD lists MSL as Not Applicable, while the HLMP-LB71-TUBDD specifies MSL 1 (Unlimited). MSL 1 represents the lowest moisture sensitivity level, indicating no special moisture control requirements during storage or handling.

Q: How does packaging affect component selection?

A: The substitute is supplied in Tape & Box (TB) packaging, which is standard for high-volume manufacturing and automated assembly. This packaging format supports standard pick-and-place equipment and storage conditions.
