MV53124A Yellow LED Diffused Rectangular Through Hole Equivalent & Substitute Parts

Part Overview

The MV53124A is a yellow LED indication component manufactured by onsemi, featuring a diffused rectangular lens with a 5.71mm x 3.17mm form factor. This through-hole mounted LED operates at 2V forward voltage with a 20mA test current and delivers 6 millicandela brightness. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MV53124A is determined by alignment across the following critical parameters:

• Color specification: Yellow
• Lens transparency: Diffused
• Lens geometry: Rectangle with Flat Top
• Mounting configuration: Through Hole
• Wavelength range: Peak wavelength 585nm to 590nm
• Forward voltage tolerance: 1.95V to 2V
• Brightness class: 5mcd to 6mcd range
• Viewing angle: 100° to 140°
• Physical dimensions: Lens size within 6.15mm x 3.65mm to 5.71mm x 3.17mm envelope

The WP1043YD from Kingbright meets these substitution criteria as an active product with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The WP1043YD serves as a functional substitute for the obsolete MV53124A based on the following factors:

• Both components maintain REACH Unaffected and MSL 1 compliance status
• Yellow diffused rectangular through-hole configuration is identical
• Peak wavelength separation of 5nm falls within acceptable yellow LED specification tolerance
• Forward voltage differential of 0.05V is within standard LED operating margin
• Viewing angle expansion from 100° to 140° provides improved light distribution
• Current rating reduction from 20mA to 10mA reflects modern LED efficiency standards
• Brightness reduction from 6mcd to 5mcd is marginal for indication applications
• Physical dimension variance accommodates standard PCB through-hole spacing

The WP1043YD is currently in active production status, ensuring supply chain availability and long-term support compared to the obsolete MV53124A.

Frequently Asked Questions (FAQ)

Q: Can WP1043YD directly replace MV53124A in existing designs?

A: Yes, for indication applications. The WP1043YD maintains compatible through-hole mounting, yellow diffused lens configuration, and operating voltage within 0.05V tolerance. Verify circuit current limiting resistor values accommodate the 10mA test current specification.

Q: What is the significance of the 5nm wavelength difference between 585nm and 590nm?

A: Both wavelengths fall within the yellow LED spectrum. The 5nm difference is imperceptible to human vision and does not affect functional performance in indication circuits.

Q: Does the lens size difference affect PCB layout compatibility?

A: The WP1043YD lens measures 6.15mm x 3.65mm versus the MV53124A at 5.71mm x 3.17mm. Verify clearance in existing mechanical enclosures and PCB apertures. Standard through-hole spacing remains compatible.

Q: Why is the test current lower on the WP1043YD?

A: The 10mA specification reflects current LED manufacturing efficiency. The component delivers comparable brightness at reduced power consumption. Existing circuit designs may operate the WP1043YD at higher current if brightness matching is required.

Q: Are there compliance or regulatory differences between these parts?

A: Both components maintain identical REACH Unaffected and MSL 1 status. No additional compliance considerations apply to substitution.

Q: What is the impact of the wider 140° viewing angle?

A: The expanded viewing angle provides superior light distribution across a broader spatial range compared to the 100° specification of the MV53124A. This is advantageous for applications requiring visibility from multiple angles.
