MV37509MP8 LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The MV37509MP8 is a quad red LED circuit board indicator manufactured by onsemi, featuring four 5mm T-1 3/4 through-hole LEDs with tinted lens and domed top configuration. Rated at 2.2V forward voltage and 20mA operating current, this component delivers 150mcd brightness across the MV3x50 series. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution for the MV37509MP8 is determined by the following critical parameters:

Primary Compatibility Criteria:

Lens size: 5mm, T-1 3/4 form factor
Mounting type: Through hole
Color: Red
Wavelength range: 623nm to 645nm peak wavelength
Forward voltage: 1.7V to 2.05V (compatible with 2.2V rating)
Operating current: 10mA to 20mA test current
Lens style: Round with domed top
Brightness: 8mcd to 900mcd (application-dependent selection)

Substitution Logic: Individual discrete red LEDs replace the quad configuration. Each substitute part operates as a single-unit replacement, requiring four units to match the original quad assembly. Substitutes are grouped by electrical characteristics (voltage and current) and optical properties (wavelength and brightness) to ensure functional equivalence in circuit board indicator applications.

Engineering Selection Recommendations

Voltage-Matched Substitutes (1.7V to 2.05V Forward Voltage): HLMP-D105, HLMP-D155-F0002, LTL2R3KEK, LTL2R3KRK, OVLLR8C7, and SSL-LX5063IC operate within the 1.7V to 2.05V range, providing direct electrical compatibility with the original 2.2V specification. All are ROHS3 compliant with MSL 1 rating. HLMP-D105 and LTL2R3KEK deliver brightness levels (240mcd and 700mcd respectively) closest to the original 150mcd rating. OVLLR8C7 offers the highest brightness at 900mcd with a wider 100° viewing angle but features a flat-top lens rather than domed.

High-Voltage Substitutes (5V and 12V): 4302H1-5V and 4302H1-12V require external voltage regulation or series resistor modification for use in 2.2V circuits. These parts are suitable only for applications with higher supply voltages. Both are ROHS3 compliant with MSL 1 rating and deliver 8mcd brightness.

Special-Function Substitute: SSL-LX5093BSRC/E operates at 3V with integrated flashing capability. This part requires circuit modification and is suitable only for applications requiring blinking indicator functionality.

Compliance Status: All substitute parts maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, matching the original specification. All are currently in active production status, ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can I use a single substitute LED to replace the quad MV37509MP8? A: No. The MV37509MP8 contains four discrete LEDs in a single package. Each substitute part is a single LED. Four individual substitute units are required to match the original quad configuration.

Q: What is the primary difference between tinted and clear lens options? A: The MV37509MP8 uses a tinted lens, while most substitutes feature clear lenses. Tinted lenses provide integrated color filtering, while clear lenses rely on the LED die color. Both achieve red indication; lens transparency affects light transmission characteristics and viewing angle performance.

Q: Are the 4302H1-12V and 4302H1-5V direct replacements? A: These parts are not direct replacements for 2.2V circuits without modification. The 4302H1-12V requires a 12V supply with series resistor; the 4302H1-5V requires a 5V supply with series resistor. Use only if your circuit can accommodate the higher voltage requirement.

Q: Which substitute offers the closest brightness match? A: HLMP-D105 (240mcd) and LTL2R3KEK (700mcd) bracket the original 150mcd specification. HLMP-D105 provides conservative brightness; LTL2R3KEK provides enhanced brightness. Selection depends on application visibility requirements.

Q: What is the significance of the 24° versus 30° versus 100° viewing angle? A: Viewing angle determines the cone of light visibility. Narrower angles (24°) concentrate light intensity in a specific direction; wider angles (100°) distribute light across a broader area. The original MV37509MP8 does not specify viewing angle. Select based on application requirements for directional versus omnidirectional indication.

Q: Can SSL-LX5093BSRC/E replace the MV37509MP8 in standard indicator applications? A: SSL-LX5093BSRC/E includes integrated flashing circuitry and operates at 3V. It is suitable only for applications requiring blinking indication and compatible with 3V supply circuits. Standard steady-state indicator applications require non-flashing alternatives.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, matching the original MV37509MP8 specification.
