MV5337 Equivalent & Substitute Parts

Part Overview

The MV5337 is a bi-color LED indicator (red/yellow) manufactured by onsemi, featuring a common cathode configuration in a T-1 3/4 through-hole radial package. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity. The MV5337 provides discrete LED indication with diffused lens optics suitable for panel-mount applications requiring dual-color status indication.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MV5337 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Color configuration: Red and Yellow bi-color LED
• Configuration type: Common Cathode
• Lens transparency: Diffused
• Lens size: 5mm, T-1 3/4
• Mounting type: Through Hole (Radial - 3 Leads)
• Forward voltage range: 2.0V to 2.1V for both colors
• Test current: 20mA for both colors
• Lens style: Round with Domed Top

The WP59EYW from Kingbright meets all critical matching parameters and qualifies as a direct substitute for the MV5337. Both components share identical mechanical form factors, electrical operating points, and functional configurations, enabling direct replacement in through-hole PCB applications.

Engineering Selection Recommendations

The WP59EYW is the qualified substitute for the obsolete MV5337. Selection is based on the following factors:

Product Status: The MV5337 is obsolete, necessitating transition to an active product. The WP59EYW maintains active manufacturing status with established supply chain availability.

Compliance & Certifications: Both components carry REACH Unaffected status. The WP59EYW additionally carries ROHS3 Compliance certification, meeting current regulatory requirements for electronic components in restricted substance directives.

Electrical Compatibility: Forward voltage specifications are within acceptable tolerance (MV5337: 2.1V Red/2.1V Yellow; WP59EYW: 2.0V Red/2.1V Yellow). Both components operate at identical test current (20mA). The 0.1V variance in red LED forward voltage is within standard LED manufacturing tolerance and does not require circuit redesign.

Mechanical Compatibility: Both components share identical package configuration (Radial - 3 Leads, T-1 3/4, 5mm lens), enabling direct PCB footprint compatibility. Height variance (10.08mm vs. 11.35mm) is within acceptable mechanical clearance for standard through-hole applications.

Optical Characteristics: The WP59EYW provides higher luminous intensity (40mcd vs. 6mcd), resulting in improved visibility. The reduced viewing angle (60° vs. 100°) may require circuit layout evaluation if wide-angle indication is critical to system function.

Frequently Asked Questions (FAQ)

Q: Can the WP59EYW directly replace the MV5337 without PCB modification?

A: Yes. Both components share identical radial 3-lead through-hole package configuration and T-1 3/4 form factor. Direct PCB footprint compatibility is confirmed. No circuit board redesign is required.

Q: What is the impact of the 0.1V forward voltage difference in the red LED?

A: The red LED forward voltage difference (2.1V MV5337 vs. 2.0V WP59EYW) falls within standard LED manufacturing tolerance. Current-limiting resistor values may require minor adjustment if precise current control is critical, but typical indicator circuit designs accommodate this variance without modification.

Q: How does the increased brightness (40mcd vs. 6mcd) affect circuit operation?

A: The WP59EYW provides approximately 6.7× higher luminous intensity. This improves visibility in ambient light conditions. No circuit modification is required; the component operates at identical test current (20mA). If reduced brightness is preferred for the application, current-limiting resistor values can be increased proportionally.

Q: What is the significance of the viewing angle difference (100° vs. 60°)?

A: The MV5337 provides a wider viewing angle (100°), while the WP59EYW has a narrower viewing angle (60°). For applications requiring wide-angle indication, circuit layout should position the WP59EYW to ensure adequate visibility from the intended viewing directions. For standard panel-mount applications with direct front-facing observation, the 60° angle is typically sufficient.

Q: Are there any compliance or regulatory differences between these components?

A: Both components carry REACH Unaffected status. The WP59EYW additionally carries ROHS3 Compliance certification, meeting current European Union Restriction of Hazardous Substances directives. The MV5337 compliance status for RoHS is not specified in available documentation.

Q: What is the maximum PCB height clearance impact of the 1.27mm height difference?

A: The WP59EYW height (11.35mm) exceeds the MV5337 (10.08mm) by 1.27mm. For applications with tight vertical clearance constraints, this variance should be evaluated against enclosure or overlay specifications. For standard through-hole applications, this difference is typically accommodated within normal mechanical tolerances.
