MV6451 LED Green Diffused T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The MV6451 is a green diffused LED indicator manufactured by onsemi, designed for through-hole mounting applications. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance requirements. The MV6451 operates at 2.3V forward voltage with a 12mcd brightness rating and 70° viewing angle, suitable for standard LED indication circuits requiring green wavelength output at 565nm peak.

Substitute Part Grouping Explanation

Substitution eligibility for the MV6451 is determined by the following critical parameters: color (green), lens transparency (diffused), lens size (5mm T-1 3/4), mounting type (through hole), package type (radial), and wavelength compatibility (565nm peak). Forward voltage and current ratings establish functional compatibility within circuit designs. Brightness (millicandela) and viewing angle variations are acceptable within the same application category provided the circuit design accommodates the electrical differences.

Substitute parts are grouped into two categories:

Category 1: Direct Mechanical and Electrical Compatibility - Parts maintaining 5mm T-1 3/4 form factor, through-hole radial mounting, green diffused lens, and 565nm wavelength with forward voltages between 2.1V and 2.3V.

Category 2: Functional Equivalents with Voltage Variations - Parts maintaining core optical and mechanical specifications but operating at different forward voltages (5V or 12V), suitable for applications where circuit voltage differs from the original design.

Engineering Selection Recommendations

Primary Substitutes (Direct Compatibility):

HLMP-3507, HLMP-3507-D0001, and HLMP-3507-D0002 from Broadcom Limited are the closest electrical and mechanical equivalents. These parts maintain the 5mm T-1 3/4 form factor, through-hole radial mounting, green diffused lens, and 565nm wavelength. Forward voltage is 2.1V (compared to 2.3V for MV6451), and test current is 10mA (compared to 20mA). These parts are active products with RoHS3 compliance and unlimited moisture sensitivity rating. Packaging options include bulk, tape & reel, and cut tape formats.

Secondary Substitutes (Voltage-Dependent Applications):

4302H5-5V and 4302H5-12V from Visual Communications Company maintain the 5mm T-1 3/4 form factor and 565nm wavelength but operate at 5V and 12V respectively. These are suitable for applications where the circuit voltage differs from the original 2.3V design. Both are active products with RoHS3 compliance.

Alternative with Brightness Consideration:

HLMP-3507-EF000 from Broadcom Limited is obsolete but maintains full mechanical and electrical compatibility with higher brightness (13.9mcd versus 12mcd). This part is suitable for direct replacement in existing designs but should not be selected for new designs due to obsolete status.

Mechanical Variant:

151051VS04000 from Würth Elektronik offers active product status and 2.1V forward voltage compatibility but features a 4.90mm diameter lens (versus 5mm) and narrower 40° viewing angle. This part is suitable only when mechanical space constraints permit the smaller lens diameter.

All recommended substitutes carry REACH Unaffected and EAR99 ECCN classifications matching the original part.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3507 directly replace MV6451 in existing circuit designs?

A: HLMP-3507 is mechanically and optically compatible with MV6451. The forward voltage is 2.1V (versus 2.3V), and test current is 10mA (versus 20mA). Circuit designs must accommodate these electrical differences. The 5mm T-1 3/4 form factor, through-hole radial mounting, and 565nm wavelength are identical.

Q: What is the difference between HLMP-3507, HLMP-3507-D0001, and HLMP-3507-D0002?

A: These three parts are electrically and optically identical. The differences are packaging formats: HLMP-3507 is bulk, HLMP-3507-D0001 is tape & reel, and HLMP-3507-D0002 is cut tape. Selection depends on assembly process requirements and order quantities.

Q: Why would I select 4302H5-5V or 4302H5-12V instead of HLMP-3507?

A: These VCC parts are selected when the circuit operates at 5V or 12V respectively, rather than 2.1V. The 5mm T-1 3/4 form factor and 565nm wavelength remain compatible. Height is 10.08mm (versus 9.19mm for HLMP-3507), which may affect PCB layout considerations.

Q: Is 151051VS04000 from Würth Elektronik a suitable substitute?

A: 151051VS04000 is mechanically and electrically compatible but features a 4.90mm diameter lens and 40° viewing angle (versus 5mm and 70° for MV6451). This part is suitable only when the narrower viewing angle and smaller lens diameter do not conflict with application requirements.

Q: What is the significance of HLMP-3507-D00B1 and HLMP-3507-D00B2?

A: These are circuit board indicator variants with right-angle mounting configuration. Lens size and height specifications are not provided in the data. These parts are suitable only for applications requiring right-angle mounting geometry, not direct replacement for radial through-hole designs.

Q: Should I use HLMP-3507-EF000 for new designs?

A: HLMP-3507-EF000 is classified as obsolete and should not be selected for new product designs. It is suitable only for maintenance and repair of existing equipment using the original MV6451. HLMP-3507 (active status) is the recommended choice for new designs.

Q: What compliance certifications apply to all substitute parts?

A: All listed substitute parts carry RoHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification, matching the original MV6451 specifications.
