HLMP-ED31-SVT00 Equivalent & Substitute Parts

Part Overview

The HLMP-ED31-SVT00 is a red 630nm LED indication component manufactured by Broadcom Limited, featuring a 5mm T-1 3/4 through-hole radial package with 3700mcd brightness rating and 2.4V forward voltage. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. Substitute parts must maintain compatibility across electrical characteristics, mechanical form factor, and mounting requirements while meeting current product availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Parameters:

• Color: Red (all substitutes)
• Mounting Type: Through Hole (all substitutes)
• Package / Case: Radial (all substitutes)
• Lens Transparency: Clear (all substitutes)
• Current - Test: 20mA (all substitutes)
• Viewing Angle: 30° (primary group) or 34° (secondary consideration)

Lens Size Grouping:

• T-1 3/4 (5mm) primary substitutes: HLMP-EG3A-WX0DD, OVLFR3C7, 7343-2USRC/S1060
• T-1 (3mm) alternative: WP710A10SECK/J3 (different form factor, requires mechanical re-evaluation)

Electrical Parameter Tolerance:

• Forward Voltage (Vf): 2.0V to 2.4V acceptable range
• Wavelength - Dominant: 623nm to 631nm acceptable range
• Millicandela Rating: 1600mcd to 7400mcd (brightness variation acceptable based on application requirements)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Replacement - T-1 3/4 Form Factor):

HLMP-EG3A-WX0DD and 7343-2USRC/S1060 are recommended as primary substitutes. Both maintain the T-1 3/4 5mm lens size, through-hole radial package, and 30° viewing angle. HLMP-EG3A-WX0DD is manufactured by Broadcom Limited (original manufacturer) with active product status and ROHS3 compliance. The 7343-2USRC/S1060 from Everlight Electronics provides parametric equivalence with matching lens size and viewing angle. Forward voltage ranges from 2.0V to 2.1V, requiring circuit evaluation for voltage-sensitive applications.

OVLFR3C7 from TT Electronics/Optek Technology maintains T-1 3/4 compatibility with 2.0V forward voltage and active product status. Height specification (8.70mm) is within tolerance of the original part (8.91mm).

Secondary Substitute (Alternative Form Factor):

WP710A10SECK/J3 from Kingbright uses a T-1 3mm lens size instead of T-1 3/4, resulting in different mechanical dimensions (2.90mm diameter, 5.90mm height). This part is suitable only for applications where PCB layout permits the smaller form factor. Brightness rating (1600mcd) is significantly lower than the original part, requiring application-specific evaluation.

Compliance Considerations:

All active substitutes meet ROHS3 compliance and REACH Unaffected status. Moisture Sensitivity Level 1 (Unlimited) is consistent across all parts, eliminating storage and handling concerns.

Frequently Asked Questions (FAQ)

Q: Can HLMP-EG3A-WX0DD directly replace HLMP-ED31-SVT00 without circuit modification?

A: HLMP-EG3A-WX0DD is mechanically and functionally compatible as a direct replacement. The forward voltage is lower (2.1V vs. 2.4V), which may require circuit evaluation if the design includes voltage-dependent current limiting. The higher brightness rating (7400mcd vs. 3700mcd) is acceptable for indication applications.

Q: Why is WP710A10SECK/J3 listed as a substitute if it has a different lens size?

A: WP710A10SECK/J3 is included as a parametric equivalent based on electrical characteristics and red wavelength compatibility. However, the T-1 3mm form factor differs from the T-1 3/4 original part, requiring mechanical re-evaluation of PCB layout and mounting hole spacing. This part is suitable only for designs where the smaller form factor is acceptable.

Q: What is the significance of the wavelength range across substitute parts?

A: Substitute parts range from 623nm to 660nm dominant wavelength, all within the red spectrum. The original part at 630nm is closely matched by HLMP-EG3A-WX0DD (626nm), OVLFR3C7 (623nm), and 7343-2USRC/S1060 (631nm). SSL-LX5093SRC39240 at 660nm represents a deeper red shift and should be evaluated for color-critical applications.

Q: Are all substitute parts available in the same packaging format?

A: HLMP-EG3A-WX0DD is supplied in Cut Tape (CT) packaging. OVLFR3C7, SSL-LX5093SRC39240, and WP710A10SECK/J3 are supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility but may influence procurement and handling procedures.

Q: What compliance certifications apply to all substitute parts?

A: All active substitute parts are ROHS3 compliant, REACH Unaffected, and classified as MSL 1 (Unlimited). ECCN and HTSUS classifications are consistent across all parts (EAR99 and 8541.41.0000 respectively).
