MV5438 Equivalent & Substitute Parts

Part Overview

The MV5438 is a bi-color LED indicator featuring green and orange light emission in a common cathode configuration. This component is designed for discrete indication applications requiring dual-color status signaling in through-hole mounting. The main part (onsemi MV5438) carries an obsolete product status, necessitating identification of active equivalent alternatives to ensure design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution eligibility for the MV5438 is determined by strict equivalence across the following critical parameters:

• Color and Configuration: Green and orange bi-color output with common cathode topology
• Optical Characteristics: Diffused white lens, round domed top, 5mm T-1 3/4 form factor, 100° viewing angle
• Electrical Performance: 2.3V forward voltage for both colors, 20mA test current
• Wavelength Specification: 565nm peak for green, 610nm peak for orange
• Mechanical Interface: Radial 3-lead through-hole mounting, 10.08mm maximum height
• Regulatory Compliance: REACH unaffected status, EAR99 classification

The Fairchild Semiconductor MV5438 meets all specified parameters and qualifies as a parametric equivalent. Product status transition from obsolete (onsemi) to active (Fairchild) provides supply continuity.

Parameter Comparison

Engineering Selection Recommendations

The Fairchild Semiconductor MV5438 is a direct parametric equivalent suitable for replacement of the obsolete onsemi MV5438. Both components share identical electrical, optical, and mechanical specifications across all critical parameters.

The Fairchild variant carries active product status, ensuring ongoing availability and supply chain support. Both components maintain REACH unaffected and EAR99 compliance classifications, satisfying regulatory requirements for equivalent substitution.

The MSL rating difference (1 versus 3) reflects manufacturing process variations between suppliers and does not affect functional equivalence for standard through-hole assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the Fairchild Semiconductor MV5438 directly replace the onsemi MV5438 in existing designs?

A: Yes. Both components are parametrically identical across all electrical, optical, and mechanical specifications. Pin configuration, voltage ratings, current requirements, and physical dimensions are equivalent. Direct substitution is supported without circuit modification.

Q: What is the significance of the MSL rating difference?

A: MSL (Moisture Sensitivity Level) indicates moisture absorption characteristics during storage and handling. The onsemi part (MSL 1) has unlimited moisture tolerance, while the Fairchild part (MSL 3) requires controlled storage conditions for 168 hours maximum. This difference does not affect functional performance and is standard for through-hole LED components from different manufacturers.

Q: Are both components compliant with international regulations?

A: Yes. Both the onsemi and Fairchild MV5438 variants maintain REACH unaffected status and EAR99 export classification, confirming compliance with applicable environmental and trade regulations.

Q: What are the key parameters that define substitution eligibility for this component?

A: Substitution is determined by equivalence in color configuration (green/orange bi-color), common cathode topology, optical properties (diffused white lens, 5mm T-1 3/4 form factor, 100° viewing angle), electrical ratings (2.3V forward voltage, 20mA test current), wavelength specifications (565nm green, 610nm orange), and through-hole radial 3-lead mounting interface.

Q: Why is the onsemi MV5438 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Fairchild Semiconductor equivalent remains in active production, providing a viable path for design continuity and supply chain management.
