MV7742 LED Orange Clear T-1 T/H Equivalent & Substitute Parts

Part Overview

The MV7742 is an orange LED indication component manufactured by onsemi, featuring a 3mm T-1 through-hole radial package with a clear domed lens. This discrete 2.1V LED operates at 20mA test current and delivers 150mcd brightness with a 60° viewing angle. The component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MV7742 are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Color: Orange
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole
• Package / Case: Radial
• Lens Style: Round with Domed Top
• Lens Transparency: Clear

Secondary Compatibility Parameters:

• Voltage - Forward (Vf): Range 2.0V to 2.2V
• Current - Test: 20mA
• Viewing Angle: 34° to 60°
• Wavelength - Peak: 605nm to 620nm

The WP710A10SECK/J4 (Kingbright) qualifies as a direct substitute, matching all primary criteria with compatible electrical specifications. The OVLBY4C7 (TT Electronics/Optek Technology) differs in color (yellow vs. orange) and therefore does not qualify as a functional equivalent for applications requiring orange indication.

Engineering Selection Recommendations

WP710A10SECK/J4 (Kingbright) - Recommended Substitute

The WP710A10SECK/J4 is the qualified substitute for the obsolete MV7742. This part maintains color specification (orange), package geometry (3mm T-1 radial through-hole), and lens configuration (clear domed). Electrical parameters remain within acceptable tolerance: forward voltage of 2.2V versus 2.1V represents a 4.8% variance, and both operate at 20mA test current. The part carries active product status with ROHS3 compliance and REACH unaffected certification, ensuring regulatory alignment and supply continuity. Height differential of 0.4mm (5.90mm vs. 6.30mm) falls within typical PCB layout tolerances for through-hole components.

OVLBY4C7 (TT Electronics/Optek Technology) - Not Recommended

The OVLBY4C7 does not qualify as a functional substitute due to color mismatch (yellow vs. orange). Although it shares identical lens size, style, and transparency, and maintains compatible electrical specifications, the wavelength difference (589nm yellow vs. 620nm orange) makes it unsuitable for applications requiring orange indication. This part should be considered only if application requirements permit yellow indication as an alternative.

Frequently Asked Questions (FAQ)

Q: Can the WP710A10SECK/J4 be used as a direct replacement for the MV7742 in existing designs?

A: Yes. The WP710A10SECK/J4 maintains identical package geometry (3mm T-1 radial through-hole), lens configuration (clear domed), and color specification (orange). Forward voltage tolerance (2.2V vs. 2.1V) and current rating (20mA) are compatible with standard LED circuit designs. PCB footprints and lead spacing remain unchanged.

Q: What is the significance of the millicandela rating difference between MV7742 (150mcd) and WP710A10SECK/J4 (3000mcd)?

A: The WP710A10SECK/J4 delivers 20 times greater luminous intensity. This increased brightness may require circuit-level current limiting adjustments to maintain desired indication levels. Applications sensitive to brightness uniformity should evaluate this parameter during qualification testing.

Q: Why is the OVLBY4C7 listed as a substitute if it is yellow, not orange?

A: The OVLBY4C7 is provided for reference only and does not qualify as a functional substitute for orange indication applications. It is included in the comparison to demonstrate why color specification is a non-negotiable substitution criterion. Selection of this part requires explicit application requirement change.

Q: Are there compliance or regulatory differences between the MV7742 and WP710A10SECK/J4?

A: The WP710A10SECK/J4 carries ROHS3 compliance certification, whereas the obsolete MV7742 does not specify this status. Both parts maintain REACH unaffected status and identical MSL rating (1 - Unlimited). The WP710A10SECK/J4 is suitable for applications with RoHS compliance requirements.

Q: How does the viewing angle difference (60° vs. 34°) affect circuit performance?

A: The MV7742 provides a wider viewing angle (60°) compared to the WP710A10SECK/J4 (34°). This means the substitute part concentrates light output in a narrower cone. Applications requiring wide-angle visibility may need optical design review or alternative component selection.

Q: What is the impact of the 0.4mm height difference on PCB layout?

A: The WP710A10SECK/J4 is 0.4mm shorter (5.90mm vs. 6.30mm). This difference is negligible for standard through-hole PCB designs and does not affect lead spacing, hole positioning, or mechanical clearance in typical applications. No layout modifications are required.
