MV53640 LED Yellow Diffused T-1 Through Hole - Equivalent & Substitute Parts

Part Overview

The MV53640 is a yellow diffused LED indicator from onsemi, designed for through-hole mounting in T-1 (3mm) form factor applications. This part operates at 2.1V forward voltage with a 10mA test current and provides 2mcd luminous intensity with a 90° viewing angle. The MV53640 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitute parts for the MV53640 are selected based on the following critical parameters:

Color Match: Yellow lens required
Lens Transparency: Diffused lens required
Mounting Type: Through hole radial package required
Lens Size: T-1 form factor (3mm nominal diameter)
Voltage Compatibility: Forward voltage within acceptable operating range (2.0V to 2.2V)
Current Rating: Test current at or above 10mA
Viewing Angle: 40° to 90° acceptable for general indication applications
Package / Case: Radial configuration required

Substitutes are grouped into two categories: direct replacements from active product lines (Rohm Semiconductor EXCELED™ series and Lumex Opto/Components) and legacy alternatives that maintain functional compatibility.

Engineering Selection Recommendations

Primary Substitute: SLR-343YY3F

The SLR-343YY3F from Rohm Semiconductor is the closest functional equivalent to the MV53640. It matches the forward voltage (2.1V), test current (10mA), and viewing angle characteristics (40° vs. 90°). The part is in active production status with ROHS3 compliance and REACH unaffected certification. Height is reduced to 5.60mm, which is compatible with standard through-hole PCB layouts. Luminous intensity is higher at 10mcd, providing improved visibility margin.

Secondary Substitute: SLR-332YY3F

The SLR-332YY3F offers the closest viewing angle match at 85°, nearly equivalent to the original 90°. Forward voltage and test current are identical (2.1V, 10mA). This part is active and ROHS3 compliant. The reduced height of 4.60mm and slightly lower luminous intensity (6.3mcd) make it suitable where space constraints exist or lower brightness is acceptable.

Alternative Substitute: SLI-343Y8Y3F

The SLI-343Y8Y3F from Rohm Semiconductor EXCELED™ series is an active product with higher luminous intensity (470mcd) and increased test current (20mA). Forward voltage is slightly elevated at 2.2V. This part is suitable for applications requiring enhanced brightness or where the higher current rating aligns with circuit design requirements. ROHS3 compliant and REACH unaffected.

Tertiary Substitute: SSL-LX305F6YD

The SSL-LX305F6YD from Lumex Opto/Components Inc. maintains the 585nm peak wavelength and provides 30mcd luminous intensity. Forward voltage is 2.2V with 20mA test current. Height is 6.25mm, nearly matching the original 6.30mm. This part is active and ROHS3 compliant, offering a direct form-factor alternative.

All recommended substitutes are in active production status with current compliance certifications, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can I use SLI-343Y8Y3F as a direct replacement for MV53640?

A: SLI-343Y8Y3F is functionally compatible but operates at higher brightness (470mcd vs. 2mcd) and requires 20mA test current instead of 10mA. It is suitable if your circuit can accommodate the increased current draw and higher luminous intensity is acceptable or beneficial.

Q: What is the difference between SLR-343YY3F and SLR-332YY3F?

A: Both are Rohm Semiconductor yellow diffused LEDs with identical electrical specifications (2.1V, 10mA). The primary differences are viewing angle (40° vs. 85°) and height (5.60mm vs. 4.60mm). SLR-332YY3F provides a wider viewing angle closer to the original MV53640 (90°), while SLR-343YY3F offers a more compact form factor.

Q: Are all substitute parts RoHS compliant?

A: Yes. All recommended substitutes are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does the 0.1V difference in forward voltage (2.1V vs. 2.2V) affect circuit compatibility?

A: The 0.1V difference is within standard LED tolerance ranges and does not require circuit redesign for typical indicator applications. Verify your current-limiting resistor design accommodates the voltage range 2.0V to 2.2V.

Q: Can I use orange-colored LEDs as substitutes?

A: No. Orange LEDs (SLI-343D8U3F, SLR-343DU3F, SSL-LX305F6SOD) operate at different wavelengths (605nm to 620nm) and are not functionally equivalent for applications requiring yellow indication.

Q: What is the impact of different millicandela ratings on my application?

A: Millicandela rating determines luminous intensity. Higher ratings (470mcd, 30mcd) provide greater brightness, while lower ratings (2mcd, 6.3mcd, 10mcd) are suitable for low-intensity indication. Select based on your visibility requirements and ambient lighting conditions.

Q: Are all substitutes available in the same packaging format?

A: Yes. All recommended substitutes use radial through-hole T-1 (3mm) packaging compatible with standard PCB layouts. Height variations (4.60mm to 6.30mm) are within acceptable tolerances for through-hole assembly.
