MV7344 Yellow LED T-1 3mm Through Hole - Equivalent & Substitute Parts

Part Overview

The MV7344 is a yellow LED indicator in T-1 3mm through-hole package manufactured by onsemi. This discrete component operates at 2.1V forward voltage with 375mcd brightness and 60° viewing angle, designed for standard indication applications. The original onsemi MV7344 is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Alternative sources and parametrically equivalent parts from active manufacturers are available to ensure supply continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MV7344 is determined by the following critical parameters:

Parametric Equivalents - Parts with identical or near-identical electrical and mechanical specifications:

• Color: Yellow
• Lens Size: 3mm, T-1
• Voltage - Forward (Vf): 2.1V ±0.1V tolerance
• Current - Test: 20mA
• Wavelength - Peak: 590nm ±10nm
• Viewing Angle: 60°
• Mounting Type: Through Hole
• Package / Case: Radial
• Height (Max): 6.30mm ±0.5mm

Similar Substitutes - Parts with compatible mechanical form factor but different electrical characteristics:

• Lens Size: 3mm, T-1
• Mounting Type: Through Hole
• Package / Case: Radial
• Color: Yellow or similar visible spectrum
• Voltage - Forward (Vf): 2.0V to 2.2V
• Current - Test: 20mA

Parts that differ in color (orange), viewing angle (narrower than 60°), or brightness (significantly higher mcd) are classified as similar substitutes requiring application-level compatibility assessment.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Direct Substitutes)

MV7344 from Fairchild Semiconductor and MV7344MP4A from Everlight Electronics are parametric equivalents with identical electrical specifications and mechanical form factors. Both are active products with current manufacturing status. Fairchild MV7344 carries ROHS3 compliance with MSL-3 rating (168 hours), while Everlight MV7344MP4A maintains MSL-1 (unlimited) rating. Both are suitable for direct replacement in applications where the original onsemi MV7344 was specified.

Similar Substitutes (Application-Dependent)

OVLBY4C7 from TT Electronics/Optek Technology is a yellow LED with identical lens size and mounting type but exhibits 10× higher brightness (3700mcd vs 375mcd) and narrower viewing angle (45° vs 60°). This part is suitable for applications requiring higher luminous intensity in a more focused beam pattern. The 0.1V lower forward voltage (2.0V vs 2.1V) is within typical circuit tolerance ranges.

WP710A10SECK/J4 from Kingbright is an orange LED with different color specification (605nm/611nm vs 590nm yellow). This part is not recommended as a direct substitute due to color mismatch, despite compatible mechanical packaging and similar brightness (3000mcd). Use only if application requirements permit orange indication instead of yellow.

Compliance and Regulatory Considerations

All substitute parts maintain REACH Unaffected and EAR99 ECCN classifications consistent with the original MV7344. ROHS3 compliance is confirmed for Fairchild and Kingbright sources. Moisture sensitivity varies: Fairchild carries MSL-3 (168 hours), while Everlight and TT Electronics maintain MSL-1 (unlimited). Storage and handling procedures should align with the selected substitute's MSL rating.

Frequently Asked Questions (FAQ)

Q: Can I use the Fairchild MV7344 as a direct replacement for the onsemi MV7344?

A: Yes. The Fairchild MV7344 is a parametric equivalent with identical electrical specifications (2.1V, 375mcd, 60° viewing angle, 590nm peak wavelength) and mechanical form factor (3mm T-1 radial through-hole). Both are yellow LEDs with clear domed lenses. The primary difference is product status (Fairchild is active) and MSL rating (Fairchild is MSL-3 vs onsemi MSL-1). For applications with standard storage conditions, this substitution is direct.

Q: What is the difference between the Everlight MV7344MP4A and the onsemi MV7344?

A: The Everlight MV7344MP4A is electrically and mechanically identical to the onsemi MV7344 (2.1V, 375mcd, 60° viewing angle, 590nm, 3mm T-1 radial). The key difference is product status: Everlight is active while onsemi is obsolete. Everlight maintains MSL-1 (unlimited) rating, matching the original onsemi specification. This part is a direct parametric equivalent suitable for new designs and production continuity.

Q: Why is the OVLBY4C7 brighter (3700mcd) than the MV7344 (375mcd)?

A: The OVLBY4C7 achieves higher luminous intensity through different LED die design and optical characteristics. While both are 3mm T-1 yellow LEDs, the OVLBY4C7 concentrates light output in a narrower viewing angle (45° vs 60°), resulting in higher brightness in the central viewing direction. This is a trade-off between brightness and viewing angle coverage. Select based on application requirements for light distribution and intensity.

Q: Can I substitute the WP710A10SECK/J4 (orange) for the MV7344 (yellow)?

A: The WP710A10SECK/J4 is mechanically compatible (3mm T-1 radial through-hole) but differs in color specification (orange 605nm/611nm vs yellow 590nm). Substitution is only appropriate if the application permits orange indication instead of yellow. Color perception and circuit design intent must be verified before substitution. This is not a direct equivalent.

Q: What does MSL rating mean for LED storage?

A: Moisture Sensitivity Level (MSL) defines maximum storage time at specified humidity and temperature before component performance may degrade. MSL-1 (unlimited) allows indefinite storage under normal conditions. MSL-3 (168 hours) limits storage to 168 hours at 85°C/85% RH before requiring baking. The onsemi and Everlight MV7344 variants carry MSL-1, while Fairchild carries MSL-3. Select based on your storage and handling capabilities.

Q: Are all these parts ROHS3 compliant?

A: ROHS3 compliance is confirmed for Fairchild MV7344, Everlight MV7344MP4A, and Kingbright WP710A10SECK/J4. The original onsemi MV7344 and TT Electronics OVLBY4C7 do not specify ROHS3 status in the provided data. If ROHS3 compliance is a requirement, select from Fairchild, Everlight, or Kingbright sources.

Q: What is the mechanical height difference between these parts?

A: The onsemi, Fairchild, and Everlight MV7344 variants all specify 6.30mm maximum height. The OVLBY4C7 is shorter at 5.35mm, and the WP710A10SECK/J4 is 5.90mm. Height differences may affect PCB layout and mechanical clearance. Verify board design accommodates the selected part's height specification.
