Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HLMP0401 are identified based on strict electrical and mechanical parameter alignment. The substitution logic is governed by the following critical parameters:

Mandatory Matching Parameters:

• Color: Yellow
• Lens Transparency: Diffused
• Lens Style: Rectangle with Flat Top
• Mounting Type: Through Hole
• Package / Case: Radial
• Viewing Angle: 100°

Allowable Tolerance Parameters:

• Voltage - Forward (Vf): Within ±0.2V of 2.2V nominal
• Millicandela Rating: Minimum 3.6mcd (≥72% of original 5mcd)
• Lens Size: Within ±0.1mm of nominal dimensions
• Height (Max): 8.00mm maximum
• Wavelength - Peak: Within ±5nm of 585nm nominal

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level 1 (Unlimited)
• Active product status

The HLMP-0401 from Broadcom Limited meets all mandatory matching parameters and falls within all allowable tolerance ranges, qualifying as a direct functional equivalent.

Engineering Selection Recommendations

Primary Selection - HLMP0401 (Everlight Electronics Co Ltd): Use the original HLMP0401 when inventory is available. This component is active, ROHS3 compliant, and delivers the specified 5mcd luminous intensity at 20mA test current with 2.2V forward voltage.

Substitute Selection - HLMP-0401 (Broadcom Limited): The Broadcom HLMP-0401 is functionally equivalent for applications where the original part is unavailable. This substitute maintains all critical electrical and mechanical parameters within engineering tolerances. The forward voltage is 0.1V lower (2.1V vs 2.2V), and luminous intensity is 3.6mcd versus 5mcd. Both components are ROHS3 compliant, MSL 1 (Unlimited), and share identical mounting type, lens geometry classification, and viewing angle specifications. The Broadcom variant is suitable for direct substitution in through-hole PCB assemblies without circuit redesign.

Compliance Verification: Both parts satisfy ROHS3 compliance and EAR99 export classification requirements. Moisture sensitivity level 1 (Unlimited) applies to both components, indicating no special storage or handling precautions beyond standard component care.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-0401 (Broadcom) directly replace the HLMP0401 (Everlight) without PCB modification?

A: Yes. Both components feature identical through-hole radial package configuration, 8.00mm maximum height, and 100° viewing angle. PCB footprints and mounting holes are compatible. No circuit board redesign is required.

Q: What is the impact of the 0.1V forward voltage difference (2.2V vs 2.1V)?

A: The Broadcom variant operates at 2.1V typical forward voltage compared to 2.2V for the Everlight part. This 0.1V difference is within standard LED manufacturing tolerances and does not require circuit recalculation for typical current-limiting resistor designs. Verify your specific circuit design if operating near voltage supply limits.

Q: Does the lower millicandela rating (3.6mcd vs 5mcd) affect visual indication performance?

A: The Broadcom HLMP-0401 delivers 3.6mcd at 20mA test current, representing 72% of the original 5mcd specification. For applications requiring maximum brightness, the original Everlight HLMP0401 is preferred. For standard indication applications with adequate ambient lighting conditions, the Broadcom substitute provides acceptable visibility within the 100° viewing angle.

Q: Are the lens dimensions interchangeable?

A: Lens dimensions vary slightly: Everlight 7.24mm x 2.42mm versus Broadcom 7.31mm x 2.35mm. These ±0.07mm variations fall within mechanical tolerance for rectangular through-hole LED applications and do not affect PCB mounting or bezel fit in standard indicator designs.

Q: Do both parts require identical handling and storage procedures?

A: Yes. Both components are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required. Standard component storage at room temperature and normal humidity is acceptable for both the Everlight HLMP0401 and Broadcom HLMP-0401.

Q: What is the wavelength difference between these parts?

A: Peak wavelength is 585nm (Everlight) versus 583nm (Broadcom), a 2nm difference within the yellow LED spectrum. Dominant wavelength for the Broadcom part is specified as 585nm. This variance is imperceptible to human vision and does not affect color matching in multi-LED indicator arrays.

Q: Are both parts currently in active production?

A: Yes. Both the HLMP0401 (Everlight) and HLMP-0401 (Broadcom) maintain active product status, ensuring continued availability and supply chain support.
