MV5437RA LED Green/Red Bicolor Through-Hole Equivalent & Substitute Parts

Part Overview

The MV5437RA is a bicolor LED indicator manufactured by onsemi, featuring green and red light emission in a 5mm T-1 3/4 through-hole radial package with three leads. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. The part delivers discrete 2.1V forward voltage operation for both color channels at 20mA test current, with diffused white lens optics and 100° viewing angle suitable for panel-mount indicator applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MV5437RA is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Bicolor green/red LED configuration with three-lead radial package
• Through-hole mounting type
• Forward voltage range: 1.9V to 2.2V for both color channels (accommodates typical circuit designs)
• Test current: 20mA per channel
• Viewing angle: 100° or greater
• Diffused lens optics
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected compliance status

Allowable Parameter Variations:

• Lens shape: Round domed or rectangular flat top (both suitable for panel mounting)
• Lens size: 5mm class (T-1 3/4 or equivalent rectangular 2×5mm)
• Millicandela rating: 2.1mcd to 6mcd per channel (brightness variation acceptable within indicator application scope)
• Peak wavelength: ±10nm tolerance (565nm±10nm Green, 635nm±10nm Red)
• Height: 8.00mm to 10.10mm (within standard through-hole PCB clearance)
• Product status: Active preferred for ongoing availability

The HLMP-0800 meets all mandatory criteria and allowable variations, qualifying as a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: HLMP-0800 (Broadcom Limited)

The HLMP-0800 qualifies as a functional equivalent for MV5437RA replacement based on the following engineering factors:

• Product Status: HLMP-0800 maintains active manufacturing and distribution status, ensuring long-term availability and supply chain continuity compared to the obsolete MV5437RA.
• Regulatory Compliance: Both components are REACH Unaffected. HLMP-0800 additionally carries ROHS3 Compliant certification, meeting current environmental and hazardous substance directives.
• Electrical Compatibility: Forward voltage specifications (2.2V Green, 1.9V Red) fall within acceptable tolerance of the original part (2.1V Green, 2.1V Red). Test current remains identical at 20mA per channel. Circuit designs using current-limiting resistors will accommodate this variation without modification.
• Optical Characteristics: Peak wavelengths (568nm Green, 635nm Red) remain within human visual perception tolerance of the original (565nm Green, 635nm Red). Viewing angle is identical at 100°.
• Mechanical Considerations: HLMP-0800 height (8.00mm) is 2.10mm shorter than MV5437RA (10.10mm), providing additional PCB clearance. Lens shape differs (rectangular flat top vs. round domed top); verify mechanical fit within existing indicator housing or bezel.
• Brightness Differential: HLMP-0800 millicandela ratings (2.6mcd Green, 2.1mcd Red) are lower than MV5437RA (6mcd Green, 6mcd Red). Assess visibility requirements in target application lighting conditions; if higher brightness is critical, alternative sources should be evaluated.
• Configuration Difference: HLMP-0800 uses Common Cathode architecture versus MV5437RA Bidirectional configuration. Verify circuit topology compatibility; Common Cathode requires single ground reference for both LED channels.

Frequently Asked Questions (FAQ)

Q: Can HLMP-0800 directly replace MV5437RA without circuit modification?

A: HLMP-0800 is electrically compatible with MV5437RA in most applications. However, the configuration difference (Common Cathode vs. Bidirectional) requires verification of your circuit topology. If your design uses a single ground reference for both LED channels, direct substitution is feasible. If your circuit requires independent control of each LED channel, circuit redesign may be necessary. Forward voltage differences (±0.1V to ±0.2V) are accommodated by standard current-limiting resistor calculations.

Q: Will the brightness difference affect indicator visibility?

A: HLMP-0800 delivers 2.6mcd Green and 2.1mcd Red compared to MV5437RA's 6mcd per channel. This represents approximately 57% lower brightness for green and 65% lower for red. In well-lit environments or applications requiring high visibility, this reduction may be noticeable. Evaluate your specific ambient lighting conditions and visibility requirements. If brightness is critical, consider alternative bicolor LED sources with higher millicandela ratings.

Q: What are the mechanical differences between these parts?

A: MV5437RA features a round lens with domed top (5mm T-1 3/4 form factor), while HLMP-0800 uses a rectangular lens with flat top (5.06mm × 2.11mm). MV5437RA height is 10.10mm maximum; HLMP-0800 is 8.00mm maximum. Both use three-lead radial through-hole packages. Verify that HLMP-0800's rectangular shape and reduced height fit your existing mechanical housing, bezel, or panel cutout designed for the original round lens.

Q: Are there compliance or regulatory concerns with substitution?

A: Both MV5437RA and HLMP-0800 are REACH Unaffected. HLMP-0800 additionally carries ROHS3 Compliant certification, meeting current environmental directives. No regulatory barriers exist for substitution in applications subject to REACH or RoHS requirements. Moisture Sensitivity Level is identical (MSL 1 - Unlimited) for both components.

Q: What is the wavelength difference impact?

A: HLMP-0800 peak wavelengths are 568nm Green (vs. 565nm) and 635nm Red (identical). The 3nm green shift is imperceptible to human vision and falls within standard color matching tolerance for indicator applications. No functional impact on color perception or application performance is expected.

Q: How should I verify compatibility before full production substitution?

A: Conduct electrical testing of HLMP-0800 in your circuit topology to confirm forward voltage operation and brightness adequacy under your target ambient lighting conditions. Perform mechanical fit verification in your indicator housing or panel assembly. Validate that Common Cathode configuration aligns with your circuit design. Test color perception and visibility in your application environment. Document any circuit modifications required for configuration compatibility.
