MV53123 Yellow LED Equivalent & Substitute Parts

Part Overview

The MV53123 is a yellow diffused rectangular LED from onsemi designed for indication applications. It features a 2.1V forward voltage, 4mcd brightness rating, and through-hole radial mounting in a 5.00mm x 2.00mm lens configuration. The product is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Suitable alternatives maintain the same electrical characteristics, mechanical form factor, and optical properties required for direct board-level replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Color and Wavelength: All substitutes must be yellow LEDs with peak wavelengths in the 583–590nm range to maintain optical consistency
• Electrical Characteristics: Forward voltage (Vf) must be 2.1V and test current must be compatible with 20mA operation
• Mechanical Form Factor: Lens dimensions must be 5.00–5.06mm x 2.00–2.11mm with rectangular flat-top configuration
• Mounting Type: All substitutes must be through-hole radial mount
• Package Configuration: Radial package / case required for direct PCB compatibility
• Height Tolerance: Maximum height must not exceed 8.00mm to ensure clearance in existing designs

The four qualified substitutes meet these criteria and are electrically and mechanically interchangeable with the MV53123.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility)

WP113YDT (Kingbright) and HLMP-S301 (Broadcom) are the preferred substitutes. Both maintain exact electrical specifications (2.1V, 20mA test current), identical lens dimensions (5.00mm x 2.00mm or 5.06mm x 2.11mm), and matching brightness ratings (4mcd). Both are active products with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory compliance.

Secondary Substitute (Reduced Test Current)

LTL-433Y (Lite-On) operates at 10mA test current versus the MV53123's 20mA specification. This part is suitable for applications where reduced current operation is acceptable. It maintains the same 2.1V forward voltage, identical lens dimensions, and offers a wider 140° viewing angle. Product status is active with ROHS3 compliance.

Tertiary Substitute (Brightness Variance)

HLMP-S301-B0000 (Broadcom) specifies 2.1mcd brightness versus the MV53123's 4mcd rating. This part is suitable only for applications where lower brightness is acceptable or beneficial. It maintains 2.1V forward voltage, 20mA test current, and active product status with ROHS3 compliance. Inventory availability is highest among all substitutes at 26,845 pieces.

All substitutes carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can WP113YDT directly replace MV53123 on existing PCBs?

A: Yes. WP113YDT matches all critical parameters: 2.1V forward voltage, 20mA test current, 4mcd brightness, 5.00mm x 2.00mm lens dimensions, and through-hole radial mounting. Physical height is 7.00mm versus 7.80mm, providing additional clearance margin.

Q: What is the difference between HLMP-S301 and HLMP-S301-B0000?

A: Both are Broadcom products with identical electrical and mechanical specifications. HLMP-S301-B0000 specifies 2.1mcd brightness while HLMP-S301 does not specify brightness. HLMP-S301-B0000 has significantly higher inventory availability (26,845 vs. 3,188 pieces). Select based on brightness requirements and availability.

Q: Is LTL-433Y suitable for my application?

A: LTL-433Y operates at 10mA test current, half the MV53123's 20mA specification. It is suitable if your circuit design accommodates reduced current operation. Brightness (3.7mcd) is slightly lower than the original (4mcd), and viewing angle is wider (140° vs. 100°). Verify circuit compatibility before selection.

Q: Do all substitutes meet RoHS compliance?

A: HLMP-S301, HLMP-S301-B0000, LTL-433Y, and WP113YDT all carry ROHS3 Compliant status. All are REACH Unaffected. Regulatory compliance is maintained across all substitutes.

Q: What is the maximum height tolerance for PCB clearance?

A: The MV53123 maximum height is 7.80mm. All substitutes fit within 8.00mm maximum height, with WP113YDT at 7.00mm and LTL-433Y at 7.50mm providing additional clearance. Verify mechanical clearance in your specific PCB layout.

Q: Are there wavelength differences between substitutes?

A: Peak wavelengths range from 583nm (Broadcom parts) to 590nm (Kingbright WP113YDT), with the original MV53123 at 585nm. All wavelengths fall within the yellow spectrum and are visually indistinguishable in indication applications. Dominant wavelengths are specified for Broadcom and Lite-On parts at 585nm and 590nm respectively.
