MV34509MP6 Equivalent & Substitute Parts

Part Overview

The MV34509MP6 is a green circuit board indicator LED manufactured by onsemi, featuring a 5mm T-1 3/4 through-hole right-angle package with a tinted domed lens. Rated at 2.2V forward voltage and 20mA operating current, this component delivers 150mcd luminous intensity at a 565nm peak wavelength. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives from active product lines that maintain compatibility with existing circuit designs and mechanical mounting requirements.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

Lens Size & Mounting: 5mm T-1 3/4 through-hole package required for mechanical compatibility
Voltage Rating: 2.2V forward voltage (±0.1V tolerance acceptable for circuit operation)
Current Rating: 20mA nominal operating current
Color & Wavelength: Green color with 565nm peak wavelength for optical consistency
Lens Configuration: Round domed top style for optical performance matching
Compliance: ROHS3 compliance and MSL 1 rating for environmental compatibility

Substitute parts are grouped into two categories based on lens transparency characteristics:

Category A - Clear Lens (Colorless Transparency): Parts with clear lens construction that provide direct wavelength visibility. These include SSL-LX5093SGC/B, SSL-LX5093GC, LTL2R3KGKNN, and LTL2P3KGKNN.

Category B - Diffused Lens (Tinted Transparency): Parts with diffused or tinted lens construction. The 4302H5-5V and 4302H5-12V are voltage-variant options with diffused green lenses, though the 12V variant requires circuit redesign.

Engineering Selection Recommendations

Primary Substitutes (Direct Replacement - 2.2V Forward Voltage)

SSL-LX5093SGC/B, SSL-LX5063GC, and WP1503GC are the preferred direct replacements. All three maintain the 2.2V forward voltage, 20mA current rating, 565nm peak wavelength, and 5mm T-1 3/4 through-hole right-angle mounting. SSL-LX5093SGC/B offers the highest luminous intensity at 300mcd, suitable for applications requiring enhanced visibility. SSL-LX5063GC and WP1503GC both deliver 100mcd, closely matching the original 150mcd specification. All three are active products with ROHS3 compliance and unlimited moisture sensitivity rating.

Secondary Substitutes (2.1V Forward Voltage - Circuit Tolerance Required)

LTL2R3KGKNN and LTL2P3KGKNN from Lite-On operate at 2.1V forward voltage, representing a 0.1V reduction from the original specification. These parts maintain 20mA current rating and 5mm T-1 3/4 through-hole mounting. LTL2R3KGKNN provides 680mcd at 30° viewing angle, while LTL2P3KGKNN delivers 980mcd at 22° viewing angle. Both are active products with ROHS3 compliance. Circuit designs with voltage regulation or current-limiting resistor networks can accommodate this voltage variance.

Alternative with Current Variance

LTL-4238 operates at 2.1V with reduced 10mA test current and 90mcd luminous intensity. This part is suitable only for applications where lower brightness and reduced current draw are acceptable.

Not Recommended for Direct Substitution

4302H5-5V and 4302H5-12V feature significantly different electrical characteristics (5V and 12V forward voltage respectively, 12-13mA current, 8mcd luminous intensity) and require complete circuit redesign. These are suitable only for new designs with different voltage supply architectures.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX5093SGC/B directly replace MV34509MP6 without circuit modification?

A: Yes. SSL-LX5093SGC/B maintains identical 2.2V forward voltage, 20mA current rating, and 5mm T-1 3/4 through-hole right-angle mounting. The 300mcd luminous intensity exceeds the original 150mcd specification, providing enhanced brightness without circuit changes.

Q: What is the difference between SSL-LX5093SGC/B and SSL-LX5093GC?

A: Both parts share identical electrical specifications (2.2V, 20mA, 565nm) and mechanical packaging. The primary difference is luminous intensity: SSL-LX5093SGC/B delivers 300mcd while SSL-LX5093GC delivers 50mcd. Selection depends on brightness requirements for the specific application.

Q: Can Lite-On LTL2R3KGKNN or LTL2P3KGKNN be used as substitutes?

A: Yes, with circuit tolerance verification. Both parts operate at 2.1V forward voltage (0.1V lower than the original 2.2V) and maintain 20mA current rating and 5mm T-1 3/4 through-hole mounting. Circuits with voltage regulation or current-limiting resistor networks can accommodate this variance. LTL2R3KGKNN provides 680mcd while LTL2P3KGKNN provides 980mcd.

Q: Why are 4302H5-5V and 4302H5-12V not recommended as direct substitutes?

A: These VCC parts operate at 5V and 12V forward voltage respectively, compared to the original 2.2V specification. Direct substitution would cause circuit malfunction. These parts are suitable only for new designs with different power supply architectures.

Q: What is the significance of lens transparency (clear vs. tinted)?

A: The original MV34509MP6 features a tinted lens, while most active substitutes feature clear lenses. Both lens types deliver green color indication at 565nm peak wavelength. Clear lens designs may appear slightly brighter due to reduced optical absorption. Application requirements for color saturation and brightness should guide lens type selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL 1 (unlimited) moisture sensitivity rating, matching the environmental compliance profile of the original MV34509MP6.

Q: What viewing angle differences exist among substitutes?

A: The original MV34509MP6 does not specify viewing angle. Substitute parts range from 16° (LTL-4238) to 60° (4302H5 series). Narrower viewing angles (16-30°) concentrate light intensity in a focused beam, while wider angles (60°) distribute light across a broader field. Application mounting geometry and visibility requirements determine optimal viewing angle selection.
