HLMP6405AYR Yellow LED Equivalent & Substitute Parts

Part Overview

The HLMP6405AYR is an active-status yellow LED indication component manufactured by Everlight Electronics Co Ltd. This surface-mount device features a yoke bend lead configuration with a clear, domed-top lens and operates at 2V forward voltage with a 10mA test current. The component is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the original HLMP6405AYR becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design modifications necessitate different mounting configurations while maintaining equivalent optical and electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the HLMP6405AYR is based on the following allowed parameters:

Mandatory Equivalence Criteria:

• Color: Yellow (all substitutes)
• Voltage - Forward (Vf): 2V (all substitutes)
• Current - Test: 10mA (all substitutes)
• Wavelength - Peak: 585nm or 583nm (within yellow spectrum range)
• Lens Style: Round with Domed Top (all substitutes)
• RoHS Status: ROHS3 Compliant (all substitutes)

Flexible Parameters (Substitution Allowed):

• Mounting Type: Surface Mount variants acceptable (Yoke Bend, Gull Wing, Axial)
• Package / Case: Different SMD configurations permitted
• Millicandela Rating: 12mcd to 20mcd range acceptable
• Viewing Angle: 25° to 28° range acceptable
• Lens Size: 1.78mm to 1.91mm Dia acceptable
• Packaging Format: Bulk, Cut Tape, Tape & Reel formats interchangeable
• Manufacturer: Broadcom Limited substitutes for Everlight Electronics

The three identified substitutes (HLMP-6405, HLMP-6405-J0011, HLMP-6405-J0021) share the base product number HLMP-6405 and maintain all mandatory electrical and optical parameters while offering alternative mounting and packaging configurations.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Recommended for SMD Assembly):

HLMP-6405-J0021 (Broadcom Limited) is the closest functional equivalent to HLMP6405AYR. Both components feature identical 2-SMD Yoke Bend package configuration, surface-mount assembly compatibility, and 2.92mm maximum height. The HLMP-6405-J0021 maintains 2V forward voltage and 10mA test current specifications. The 20mcd brightness rating exceeds the original 12mcd specification, providing enhanced optical output. The 28° viewing angle is marginally wider than the original 25°, suitable for applications requiring broader light distribution. Peak wavelength of 583nm remains within the yellow spectrum range (585nm original). ROHS3 compliance is maintained. Tape & Reel packaging format supports high-volume automated assembly.

Alternative for SMD Assembly (Gull Wing Configuration):

HLMP-6405-J0011 (Broadcom Limited) provides surface-mount compatibility with alternative gull wing lead configuration. Electrical specifications (2V, 10mA, 20mcd) match the HLMP-6405-J0021. This option is suitable when PCB layout requires gull wing lead geometry. Cut Tape & Digi-Reel packaging supports both manual and automated placement. Height and wavelength specifications remain equivalent.

Alternative for Through-Hole Assembly:

HLMP-6405 (Broadcom Limited) is a through-hole axial configuration substitute. This option applies only when design modification permits transition from surface-mount to through-hole assembly. Electrical and optical parameters (2V, 10mA, 20mcd, 583nm) remain equivalent. Axial flat-lead configuration requires different PCB footprint design. Bulk packaging format is available. This substitute is not recommended for direct replacement in existing SMD designs without PCB redesign.

Compliance Verification:

All three substitutes maintain ROHS3 compliance status. HLMP-6405-J0021 and HLMP-6405-J0011 include REACH Unaffected status documentation. Moisture sensitivity level (MSL 2A, 4 Weeks) for Broadcom substitutes differs from original MSL 1 (Unlimited); storage and handling procedures must be adjusted accordingly.

Frequently Asked Questions (FAQ)

Q: Can HLMP-6405-J0021 replace HLMP6405AYR in existing PCB designs without modification?

A: Yes. Both components feature identical 2-SMD Yoke Bend surface-mount package configuration and 2.92mm maximum height. PCB footprint, solder pad layout, and assembly process remain compatible. No design modification is required.

Q: What is the difference between the 12mcd (original) and 20mcd (substitutes) brightness ratings?

A: The substitute parts provide 67% higher light output at identical 10mA test current. This increased brightness is acceptable for indication applications where enhanced visibility is beneficial or neutral. Applications with strict brightness specifications should verify that 20mcd output does not exceed design limits.

Q: Are the wavelength differences (585nm vs 583nm) significant?

A: Both wavelengths fall within the yellow spectrum range and produce visually equivalent yellow light output. The 2nm difference is imperceptible to human vision and does not affect functional performance in indication applications.

Q: Can HLMP-6405 (through-hole axial) be used as a substitute?

A: HLMP-6405 is electrically and optically equivalent but requires PCB redesign. The through-hole axial configuration has different footprint requirements than the surface-mount yoke bend original. This substitute applies only when design modification is acceptable.

Q: What is the impact of MSL 2A (4 Weeks) moisture sensitivity on Broadcom substitutes?

A: Broadcom substitutes require controlled storage at specified humidity levels with a 4-week floor-life limit after bag opening. Original HLMP6405AYR has unlimited moisture sensitivity (MSL 1). Procurement, storage, and assembly procedures must implement moisture control protocols. Desiccant packaging and bake-out procedures may be required before assembly.

Q: Are all three substitutes available in equivalent packaging quantities?

A: Packaging formats differ. HLMP-6405-J0021 is available in Tape & Reel format (11,704 Pcs inventory). HLMP-6405-J0011 is available in Cut Tape & Digi-Reel format (1,757 Pcs inventory). HLMP-6405 is available in Bulk format (11,802 Pcs inventory). Selection depends on assembly process requirements and procurement volume.

Q: Can HLMP-6405-J0011 (gull wing) be used instead of HLMP-6405-J0021 (yoke bend)?

A: Both are surface-mount SMD components with equivalent electrical and optical specifications. However, gull wing and yoke bend lead geometries require different PCB footprints and solder pad layouts. Direct substitution without PCB modification is not possible. Selection depends on existing PCB design.

Q: What certifications apply to all substitute parts?

A: All substitutes maintain ROHS3 compliance. HLMP-6405-J0021 and HLMP-6405-J0011 include REACH Unaffected status. All parts carry EAR99 ECCN classification and 8541.41.0000 HTSUS code. Regulatory documentation is equivalent across all options.
