HLMP0401 Equivalent & Substitute Parts

Part Overview

The HLMP0401 is a yellow diffused rectangular through-hole LED manufactured by onsemi, designed for indication applications. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The HLMP0401 delivers 5mcd at 2.2V forward voltage with a 585nm peak wavelength and 100° viewing angle in a radial package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HLMP0401 are qualified based on the following electrical and mechanical parameters:

• Color and Wavelength: Yellow indication with 585nm peak wavelength
• Lens Configuration: Diffused rectangular lens with flat top
• Mounting and Package: Through-hole radial package
• Electrical Compatibility: Forward voltage range 2.1V–2.2V, test current 20mA
• Optical Performance: 100° viewing angle
• Physical Dimensions: Maximum height 8.00mm, compatible lens size range
• Environmental Compliance: MSL 1 (Unlimited), REACH Unaffected, EAR99 classification

The substitute parts HLMP-0401, HLMP-0401-B0000, and HLMP-0401-D0002 from Broadcom Limited meet these criteria with active product status and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All three Broadcom Limited substitute parts maintain active product status and provide RoHS3 compliance, addressing the obsolescence of the original onsemi HLMP0401. Selection between substitutes depends on application requirements:

HLMP-0401 (Bulk Packaging): Suitable for standard production volumes with 3.6mcd brightness and bulk packaging format.

HLMP-0401-B0000 (Bulk Packaging, Lower Brightness): Appropriate for applications requiring reduced brightness at 1.4mcd with bulk packaging.

HLMP-0401-D0002 (Tape & Reel Packaging): Designed for automated assembly processes with 3.6mcd brightness and tape & reel packaging format.

All substitutes operate at 2.1V forward voltage, 0.1V lower than the original part, and maintain electrical compatibility at the 20mA test current. Peak wavelength shifts from 585nm to 583nm across all Broadcom alternatives, remaining within yellow indication specifications. Physical dimensions and mounting characteristics are preserved across all options.

Frequently Asked Questions (FAQ)

Q: Can HLMP-0401-B0000 replace HLMP0401 in brightness-critical applications?

A: HLMP-0401-B0000 operates at 1.4mcd compared to the original 5mcd. This substitute is suitable only for applications where reduced brightness is acceptable. For equivalent brightness, use HLMP-0401 or HLMP-0401-D0002 at 3.6mcd.

Q: What is the difference between HLMP-0401 and HLMP-0401-D0002?

A: Both parts are electrically and optically identical at 3.6mcd, 2.1V, and 583nm peak wavelength. The primary difference is packaging: HLMP-0401 uses bulk packaging, while HLMP-0401-D0002 uses tape & reel format for automated assembly.

Q: Is the 0.1V forward voltage difference between HLMP0401 (2.2V) and Broadcom substitutes (2.1V) significant?

A: The 0.1V difference is within typical LED tolerance ranges and does not affect circuit compatibility. Existing designs operating at 2.2V will function with 2.1V parts without modification.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All three Broadcom Limited substitutes carry RoHS3 compliance certification, meeting current environmental regulations. The original onsemi HLMP0401 does not specify RoHS status.

Q: Which substitute should be selected for new production designs?

A: For new designs, select based on assembly method: HLMP-0401 or HLMP-0401-B0000 for manual assembly with bulk packaging, or HLMP-0401-D0002 for automated pick-and-place assembly with tape & reel packaging. All maintain active product status and long-term availability.
