HLMP0400 Equivalent & Substitute Parts

Part Overview

The HLMP0400 is a yellow diffused rectangular through-hole LED manufactured by onsemi, designed for indication applications. It features a 2.2V forward voltage with 2.5mcd brightness at 20mA test current and a 100° viewing angle. The product is currently obsolete, making identification of compatible substitute components essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HLMP0400 is determined by the following critical parameters:

• Color and wavelength characteristics (yellow, 585nm peak wavelength)
• Lens configuration (diffused, rectangular with flat top)
• Electrical specifications (forward voltage 2.1V–2.2V, 20mA test current)
• Mechanical compatibility (through-hole radial package, 8.00mm maximum height)
• Viewing angle (100°)
• Physical dimensions (rectangular lens approximately 7.24–7.31mm length, 2.35–2.42mm width)

The HLMP-0401-B0000 from Broadcom Limited meets these substitution criteria. Both components share identical mounting type, package style, viewing angle, and maximum height. Forward voltage differs by 0.1V (within typical LED tolerance), and lens dimensions are within acceptable mechanical tolerance. The substitute maintains the same wavelength classification and diffused lens transparency required for indication applications.

Engineering Selection Recommendations

The HLMP-0401-B0000 is the qualified substitute for the obsolete HLMP0400. Selection is supported by:

• Active product status with current manufacturing availability
• RoHS3 compliance and REACH unaffected designation, matching the regulatory profile of the original component
• Identical mounting configuration and mechanical envelope (8.00mm height, through-hole radial package)
• Compatible electrical operation within standard LED tolerance (2.1V vs. 2.2V forward voltage)
• Equivalent optical characteristics (100° viewing angle, diffused yellow lens, 583–585nm wavelength range)

The substitute exhibits lower brightness (1.4mcd vs. 2.5mcd) and slightly different lens dimensions (7.31mm x 2.35mm vs. 7.24mm x 2.42mm). These differences are within acceptable mechanical tolerance for through-hole PCB mounting and do not affect functional compatibility in indication applications where absolute brightness matching is not critical.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-0401-B0000 be used as a direct replacement for the HLMP0400?

A: Yes. Both components share identical mounting type, package style, viewing angle, and maximum height. Forward voltage differs by 0.1V, which is within standard LED operating tolerance. Lens dimensions are mechanically compatible for through-hole PCB assembly.

Q: What is the brightness difference between these parts?

A: The HLMP0400 is rated at 2.5mcd while the HLMP-0401-B0000 is rated at 1.4mcd at 20mA test current. The substitute is approximately 44% less bright. Brightness requirements must be evaluated against specific application needs.

Q: Are there mechanical fit concerns?

A: Lens dimensions differ slightly (7.24mm x 2.42mm vs. 7.31mm x 2.35mm). Both components maintain the same rectangular flat-top profile and 8.00mm maximum height. These variations are within standard mechanical tolerance for through-hole mounting and do not affect PCB assembly or mechanical fit.

Q: What is the wavelength difference?

A: The HLMP0400 has a 585nm peak wavelength while the HLMP-0401-B0000 has a 583nm peak wavelength. Both are classified as yellow indication LEDs and are visually indistinguishable in typical applications.

Q: Does the substitute meet the same regulatory requirements?

A: The HLMP-0401-B0000 is RoHS3 compliant and REACH unaffected, matching the regulatory status of the original HLMP0400. Both components carry EAR99 ECCN classification and identical HTSUS codes.

Q: What is the forward voltage difference and does it matter?

A: The substitute operates at 2.1V typical forward voltage compared to 2.2V for the original. This 0.1V difference is within standard LED tolerance and does not require circuit redesign for typical indication applications using current-limiting resistors.
