MV5437 Equivalent & Substitute Parts

Part Overview

The MV5437 is a bi-color LED indicator (green/red) manufactured by onsemi in a T-1 3/4 through-hole radial package with 3 leads and common cathode configuration. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The MV5437 provides dual-color indication capability with diffused lens optics suitable for general-purpose status indication applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MV5437 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters:

• Color configuration (Green/Red dual-color)
• Configuration type (Common Cathode)
• Forward voltage range (Vf Green and Red within ±0.2V tolerance)
• Test current (20mA nominal)
• Wavelength compatibility (Peak wavelengths within ±10nm for green, ±10nm for red)

Mechanical Parameters:

• Lens size (5mm, T-1 3/4 form factor)
• Package type (Radial - 3 Leads)
• Mounting type (Through Hole)
• Lens transparency (Diffused)
• Lens style (Round with Domed Top)

Compliance Parameters:

• Moisture Sensitivity Level (MSL 1 - Unlimited)
• REACH compliance status
• RoHS compliance status (where applicable)

Substitute parts meeting these criteria are electrically and mechanically interchangeable with the MV5437 in standard PCB applications. Brightness (millicandela rating) and viewing angle variations are acceptable within the same package form factor, as these parameters are application-dependent and do not affect physical or electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are electrically and mechanically compatible with the MV5437 within standard PCB design tolerances. Selection among active alternatives should be based on the following criteria:

For Direct Replacement with Minimal Design Changes: SSL-LX5097IGW (Lumex Opto/Components Inc.) provides the closest electrical match to the MV5437, with identical forward voltages (2.1V green/red), matching test currents (20mA), and equivalent wavelengths (565nm green, 635nm red). This part is ROHS3 compliant and REACH unaffected, with active product status and high inventory availability (40,747 pcs).

For Applications Requiring Higher Brightness: WP59EGW (Kingbright) offers significantly higher millicandela ratings (60mcd green, 40mcd red) compared to the MV5437 (6mcd each), suitable for applications requiring enhanced visibility. Forward voltages are slightly elevated (2.2V green, 2.0V red) and height is greater (11.35mm vs. 10.08mm). ROHS3 compliant and REACH unaffected.

For Lower Current Applications: HLMP-4000 (Broadcom Limited) operates at reduced test currents (10mA vs. 20mA), reducing power consumption. Forward voltages are slightly higher (2.2V green, 1.9V red). ROHS3 compliant and REACH unaffected.

For Narrow Viewing Angle Applications: 5BC-3 (Bivar Inc.) provides a narrower viewing angle (40° vs. 100°), suitable for applications requiring directional indication. Brightness is higher (35mcd green/red). ROHS3 compliant.

All substitute parts maintain common cathode configuration, 5mm T-1 3/4 form factor, radial 3-lead package, through-hole mounting, and diffused lens characteristics required for direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the MV5437?

A: Yes. All listed substitute parts share the same mechanical package (5mm T-1 3/4 radial 3-lead through-hole), electrical configuration (common cathode), and color capability (green/red). They are electrically and mechanically interchangeable in standard PCB applications without requiring circuit modifications.

Q: What is the main difference between the MV5437 and its substitutes?

A: The MV5437 is obsolete. All substitute parts are active products with current manufacturing support. Brightness levels (millicandela ratings) and viewing angles vary among substitutes, but these differences do not affect physical compatibility or basic electrical operation.

Q: Does forward voltage variation affect compatibility?

A: Forward voltage variations among substitutes (ranging from 1.9V to 2.2V for red, 2.1V to 2.2V for green) are within acceptable design tolerances for standard current-limiting resistor circuits. Existing resistor values will function with all substitutes; however, brightness output may vary slightly. For critical applications, resistor values can be adjusted to maintain consistent brightness across different part selections.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are ROHS3 compliant. The original MV5437 RoHS status is not specified in available documentation.

Q: What is the significance of viewing angle differences?

A: Viewing angle (ranging from 40° to 100° among substitutes) determines the angular range over which the LED remains visible at acceptable brightness levels. The MV5437 offers the widest viewing angle (100°). Narrower viewing angles (such as 5BC-3 at 40°) are suitable for directional indication applications. This parameter does not affect electrical compatibility.

Q: Can I mix different substitute parts in the same design?

A: Yes. All substitute parts are mechanically and electrically compatible. However, brightness and viewing angle differences may result in inconsistent visual appearance across multiple indicators. For aesthetic consistency, use the same part number throughout a design.

Q: What is MSL 1 (Unlimited) significance?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and does not require special handling, storage, or baking procedures prior to soldering. All listed parts share this rating.

Q: Which substitute offers the closest performance match to the MV5437?

A: SSL-LX5097IGW provides the closest electrical match with identical forward voltages (2.1V), matching test currents (20mA), and equivalent wavelengths. It is recommended for applications requiring minimal design changes from the original MV5437 specification.
