MV7342 LED Yellow Clear T-1 Through Hole - Equivalent & Substitute Parts

Part Overview

The MV7342 is a yellow LED indicator from onsemi, featuring a 3mm T-1 through-hole package with a clear domed lens. This component delivers 150mcd at 2.1V forward voltage and is designed for discrete LED indication applications. The product is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility across mechanical form factor, electrical performance envelope, and mounting characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MV7342 is determined by the following critical parameters:

Mechanical Compatibility: All substitute parts must feature 3mm T-1 through-hole radial package configuration with clear lens transparency to maintain PCB layout and optical performance consistency.

Electrical Compatibility: Forward voltage (Vf) must fall within the operational range of the original circuit design. The MV7342 operates at 2.1V typical; substitutes with Vf between 2.0V and 2.2V are electrically compatible at 20mA test current.

Optical Performance: Wavelength-peak specification (590nm region) and viewing angle (45° to 60°) define the visual indication characteristics. Millicandela rating variance is acceptable provided the substitute delivers sufficient brightness for the intended indication function.

Environmental & Compliance: All substitutes must maintain MSL 1 rating and REACH Unaffected status to ensure compatibility with standard manufacturing and regulatory requirements.

Three substitute parts meet these criteria: HLMP-NL06 (Broadcom Limited, amber 590nm), OVLBY4C7 (TT Electronics/Optek Technology, yellow 589nm), and WP710A10SECK/J4 (Kingbright, orange 605nm).

Parameter Comparison

Engineering Selection Recommendations

OVLBY4C7 (TT Electronics/Optek Technology) is the primary substitute for yellow indication applications. This part maintains yellow color specification (589nm peak wavelength), operates within the compatible voltage range (2V Vf), and is ROHS3 compliant with active product status. The significantly higher millicandela rating (3700mcd versus 150mcd) provides enhanced brightness margin. Height (5.35mm) is within acceptable PCB clearance tolerance relative to the original 6.30mm specification.

HLMP-NL06 (Broadcom Limited) serves as an alternative for applications where amber indication is acceptable. This part matches the 60° viewing angle of the original design and operates at 2.02V Vf, requiring minimal circuit adjustment. ROHS3 compliance and active product status ensure long-term availability. The lower millicandela rating (96.2mcd) may require circuit optimization for adequate brightness.

WP710A10SECK/J4 (Kingbright) is suitable for orange indication applications. This part delivers 3000mcd brightness at 2.2V Vf and maintains ROHS3 compliance with active product status. The narrower 34° viewing angle represents a functional trade-off compared to the original 60° specification and should be evaluated against specific application requirements.

All three substitutes maintain through-hole radial package compatibility, MSL 1 rating, and REACH Unaffected status, ensuring compatibility with standard manufacturing processes and regulatory frameworks.

Frequently Asked Questions (FAQ)

Q: Can OVLBY4C7 directly replace MV7342 without circuit modification?

A: OVLBY4C7 is mechanically and electrically compatible. The forward voltage difference (2V versus 2.1V) is within standard circuit tolerance for LED indication circuits. The significantly higher brightness (3700mcd versus 150mcd) may require current-limiting resistor adjustment if the original circuit was optimized for the lower brightness specification.

Q: What is the primary difference between the three substitute options?

A: The substitutes differ in color specification and brightness. OVLBY4C7 maintains yellow indication with high brightness. HLMP-NL06 provides amber indication with lower brightness. WP710A10SECK/J4 delivers orange indication with high brightness but narrower viewing angle. Selection depends on the specific color requirement and brightness tolerance of the application.

Q: Are all substitutes RoHS compliant?

A: Yes. HLMP-NL06, OVLBY4C7, and WP710A10SECK/J4 are all ROHS3 compliant. The original MV7342 RoHS status was not specified in available documentation.

Q: Does the height difference between MV7342 (6.30mm) and substitutes affect PCB layout?

A: All substitutes have maximum heights between 5.35mm and 6.20mm, which are within acceptable tolerance for standard through-hole LED mounting. PCB clearance should be verified against specific board design constraints, but the dimensional variance is not a limiting factor for typical applications.

Q: What is the impact of viewing angle differences on application performance?

A: The MV7342 and HLMP-NL06 both feature 60° viewing angles, providing wide-angle indication. OVLBY4C7 (45°) and WP710A10SECK/J4 (34°) have narrower viewing angles, which may limit visibility from extreme angles. Application requirements should determine whether narrower viewing angle is acceptable.

Q: Are all substitutes available in bulk packaging?

A: Yes. HLMP-NL06, OVLBY4C7, and WP710A10SECK/J4 are all available in bulk packaging, consistent with standard procurement for production applications.
