MV7744 LED Orange Clear T-1 T/H Equivalent & Substitute Parts

Part Overview

The MV7744 is a through-hole orange LED indicator manufactured by onsemi, featuring a 3mm T-1 package with a clear domed lens. This component is designed for discrete LED indication applications requiring a 2.1V forward voltage at 20mA test current. The product status is obsolete, making identification of equivalent and substitute parts essential for ongoing design support and component procurement.

Engineering Selection Recommendations

WP710A10SECK/J4 (Kingbright) is the primary substitute for direct replacement of the MV7744. This part maintains orange color specification and operates within compatible electrical parameters (2.2V forward voltage versus 2.1V). The part is currently active in production with RoHS3 compliance certification. Physical dimensions are comparable with a maximum height of 5.90mm versus 6.30mm for the original part. The higher millicandela rating (3000mcd versus 375mcd) and narrower viewing angle (34° versus 60°) represent performance enhancements suitable for most indication applications.

OVLBY4C7 (TT Electronics/Optek Technology) serves as a functional substitute where yellow indication is acceptable in place of orange. This part meets all mechanical and environmental requirements with active product status and RoHS3 compliance. Forward voltage is 2V, within the acceptable range for circuit compatibility. The higher brightness rating (3700mcd) and intermediate viewing angle (45°) provide alternative optical characteristics.

Selection between WP710A10SECK/J4 and OVLBY4C7 depends on color requirement specifications in the application circuit. Both parts satisfy REACH compliance and moisture sensitivity requirements identical to the original MV7744.

Frequently Asked Questions (FAQ)

Q: Can WP710A10SECK/J4 be used as a direct replacement for MV7744?

A: Yes. Both parts share the 3mm T-1 through-hole radial package, clear lens, and compatible electrical operating parameters (forward voltage 2.1V to 2.2V at 20mA test current). Physical dimensions are comparable. The primary difference is the higher brightness rating of the Kingbright part.

Q: What is the difference between WP710A10SECK/J4 and OVLBY4C7?

A: The primary difference is color: WP710A10SECK/J4 is orange (620nm peak wavelength), while OVLBY4C7 is yellow (589nm dominant wavelength). Both maintain identical package form factors and mounting types. OVLBY4C7 has a slightly lower forward voltage (2V) and higher brightness (3700mcd). Selection depends on application color requirements.

Q: Are there viewing angle differences between these parts?

A: Yes. The MV7744 has a 60° viewing angle, WP710A10SECK/J4 has 34°, and OVLBY4C7 has 45°. Narrower viewing angles concentrate light intensity in a smaller cone, resulting in higher brightness in the direct viewing direction. Application requirements determine whether the narrower angle is acceptable.

Q: Do all substitute parts meet compliance requirements?

A: Yes. Both WP710A10SECK/J4 and OVLBY4C7 are REACH Unaffected and carry RoHS3 compliance certification. All parts have MSL rating of 1 (Unlimited), matching the original MV7744 moisture sensitivity specification.

Q: What is the height difference between MV7744 and the substitute parts?

A: MV7744 has a maximum height of 6.30mm. WP710A10SECK/J4 is 5.90mm, and OVLBY4C7 is 5.35mm. Both substitutes are shorter, which may be advantageous for space-constrained PCB layouts.

Q: Can OVLBY4C7 be used if the circuit specifically requires orange indication?

A: No. OVLBY4C7 is yellow (589nm), not orange. If orange color is a functional requirement, WP710A10SECK/J4 is the appropriate substitute. If color is not functionally critical, OVLBY4C7 is electrically compatible.
