Frequently Asked Questions (FAQ)

Q: Can the HLMP-AL65-23KDD directly replace the QLMP-AL78-23KDD in existing designs?

A: Yes. Both parts share identical package type (5mm through-hole radial), color specification (amber), and regulatory classification. The substitute is mechanically and electrically compatible for direct board-level replacement.

Q: What are the key differences between these parts?

A: The primary difference is product status: the QLMP-AL78-23KDD is obsolete, while the HLMP-AL65-23KDD is active. The substitute provides documented electrical parameters (2.1V forward voltage, 20mA test current, 590nm dominant wavelength) and ROHS3 compliance certification. Both maintain identical regulatory status and package configuration.

Q: Are there any mechanical compatibility concerns?

A: No. Both parts use 5mm through-hole radial packages with identical mounting type. The HLMP-AL65-23KDD features a round domed-top lens with diffused transparency, maintaining standard 5mm LED form factor compatibility.

Q: What is the inventory status for the substitute part?

A: The HLMP-AL65-23KDD has 814 pieces of new original stock currently available, providing reliable supply for production requirements.

Q: Does the substitute meet current environmental standards?

A: Yes. The HLMP-AL65-23KDD is ROHS3 compliant and maintains REACH Unaffected status, meeting current environmental and regulatory requirements.
