Key Parameters

Substitute Part Grouping Explanation

Substitution of the QLMP-1642-EFD00 is based on the following critical parameters:

Color and Wavelength Compatibility: The substitute part must emit green light at the same dominant wavelength (569nm) to maintain visual indication consistency in the application.

Lens Size and Form Factor: The original part specifies a 3mm lens size. The substitute HLMP-1641 maintains this 3mm T-1 form factor, ensuring mechanical compatibility with existing PCB layouts and mechanical assemblies.

Mounting Configuration: The QLMP-1642-EFD00 requires a substitute with compatible mounting characteristics. The HLMP-1641 provides Through Hole radial mounting, which is the standard configuration for discrete 3mm LED applications.

Electrical Characteristics: Forward voltage (Vf), test current, and luminous intensity must align with circuit design parameters to ensure proper operation without requiring circuit modifications.

Regulatory Compliance: Both parts must maintain equivalent ECCN classification (EAR99) and HTSUS coding (8541.41.0000) for supply chain continuity.

Product Status: The substitute part must have Active product status to ensure long-term availability and continued manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The HLMP-1641 is the identified substitute for the obsolete QLMP-1642-EFD00 based on the following engineering criteria:

Product Status Alignment: The HLMP-1641 maintains Active product status, ensuring continued availability from Broadcom Limited and long-term supply chain reliability.
