Mounting Type: Through Hole (Radial)
Configuration: Single LED
Voltage Range: 1.9V to 2.2V forward voltage (Vf)
Current Rating: 20mA test current
Lens Style: Round with Domed Top

Secondary Compatibility Factors:

Wavelength: 583nm to 592nm peak wavelength range

Engineering Selection Recommendations

Tier 1 - Direct Substitutes (Highest Compatibility):

4308H7 (VCC) and HLMP-C323 (Broadcom) are the closest electrical and mechanical equivalents. Both maintain 2.1V to 2.2V forward voltage, 20mA current rating, 5mm T-1 3/4 package, and comparable brightness (140mcd to 170mcd). Both are ROHS3 compliant and active products with unlimited moisture sensitivity rating. These parts require no circuit modifications and provide equivalent performance in standard indicator applications.

Tier 2 - Compatible Substitutes (Minor Parameter Variance):

151051YS04000 (Würth Elektronik), OVLLY8C7 (TT Electronics/Optek), SSL-LX5063YC, SSL-LX5093YC, and WP1503YC operate within acceptable voltage and current parameters (1.9V to 2.1V, 20mA). All are active products with ROHS3 compliance. Brightness and viewing angle vary; OVLLY8C7 offers significantly higher brightness (980mcd) and wider viewing angle (100°), while SSL-LX5063YC and SSL-LX5093YC provide lower brightness (40mcd). These parts are suitable where brightness variation is acceptable within application requirements.

Tier 3 - Limited Compatibility (Significant Parameter Deviation):

5219284F and 5219321F (Dialight) deviate substantially from the original specification. 5219284F operates at 10V with 10mA current and 8mcd brightness, unsuitable for 2.2V circuits. 5219321F operates at 1.9V with only 2mA current and 1.8mcd brightness, providing insufficient brightness for standard indicator use. These parts are not recommended as direct substitutes.

Color Variant:

LTL2R3KFK (Lite-On) is an orange LED (605nm to 611nm wavelength) with 700mcd brightness. This part is electrically compatible but provides different color output and is suitable only where orange indication is acceptable as a design change.

Frequently Asked Questions (FAQ)

Q: Can I use OVLLY8C7 as a direct replacement for MV33509MP5?

A: Yes, OVLLY8C7 is electrically compatible. Both operate at approximately 2V forward voltage and 20mA current with 5mm T-1 3/4 through-hole mounting. However, OVLLY8C7 provides significantly higher brightness (980mcd versus 150mcd) and a wider viewing angle (100° versus unspecified). If brightness is controlled by series resistor in your circuit, this substitution is valid. If brightness is critical to application function, verify that the higher output does not cause issues.

Q: What is the difference between clear and tinted lens types?

A: The original MV33509MP5 uses a tinted lens, which provides inherent color filtering. Clear lens substitutes like 4308H7, HLMP-C323, and OVLLY8C7 rely on the LED die color for wavelength output. Both approaches produce yellow light in the 583nm to 592nm range. Clear lens designs typically offer higher brightness and wider viewing angles. Tinted lenses provide more uniform color appearance across viewing angles.

Q: Are SSL-LX5063YC and SSL-LX5093YC interchangeable?

A: Both parts are electrically identical (2.1V, 20mA, 40mcd, 585nm peak wavelength, 5mm T-1 3/4 package). The primary difference is physical height: SSL-LX5063YC is 6.00mm maximum height, while SSL-LX5093YC is 8.60mm maximum height. Select based on available PCB clearance. Both are suitable substitutes for MV33509MP5 in applications where lower brightness (40mcd) is acceptable.

Q: Why is LTL2R3KFK listed as a substitute if it is orange, not yellow?

A: LTL2R3KFK is included because it meets the electrical compatibility criteria (2.05V forward voltage, 20mA current, 5mm T-1 3/4 through-hole package) and is referenced in the original part's substitute list. However, the orange color (605nm to 611nm wavelength) represents a functional change. This part is suitable only where orange indication is an acceptable design modification or where color-blind compatibility is required.

Q: What does "Product Status: Active" mean for substitution purposes?

A: Active status indicates the part is currently manufactured and available from the supplier. The original MV33509MP5 is obsolete, meaning onsemi no longer manufactures it. All recommended substitutes carry active status, ensuring long-term availability for production and future orders. This is a critical factor for supply chain continuity.

Q: Can I substitute 5219284F or 5219321F for MV33509MP5?

A: No. 5219284F requires 10V operation (versus 2.2V) and delivers only 8mcd brightness, making it unsuitable for standard 2.2V circuits. 5219321F operates at 1.9V with 2mA current and 1.8mcd brightness, providing insufficient brightness for indicator applications. Neither part is recommended as a substitute.

Q: What is the significance of the 585nm to 592nm wavelength range?

A: This range defines the yellow color output. The original MV33509MP5 peaks at 585nm. All recommended substitutes fall within 583nm to 592nm, ensuring consistent yellow color perception. LTL2R3KFK at 611nm appears orange rather than yellow and should not be used where yellow indication is required.

Q: Do all substitutes have the same moisture sensitivity rating?

A: Yes. The original MV33509MP5 and all listed substitutes carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity concerns. All parts are suitable for standard PCB assembly processes without special moisture control requirements.
