Substitute Part Grouping Explanation

Substitution eligibility for the MV37509MP7 is determined by the following critical parameters:

Lens Size & Mounting: 5mm T-1 3/4 through-hole configuration ensures mechanical and electrical compatibility
Color & Wavelength: Red spectrum (630-645nm peak wavelength range) maintains visual consistency
Current Rating: 20mA nominal operation supports direct circuit integration
Voltage Compatibility: Forward voltage between 1.7V and 2.2V allows operation within standard LED circuit designs
Brightness Range: 150mcd minimum maintains adequate visibility for circuit board indication applications
Lens Transparency: Clear or tinted lenses provide equivalent optical performance
Product Status: Active status ensures ongoing availability and supply chain reliability

Substitute parts are grouped into two categories: direct equivalents (identical electrical and mechanical specifications) and functional alternatives (compatible within the specified parameter ranges).

Engineering Selection Recommendations

Direct Equivalent (Preferred for Drop-In Replacement):

MV37509MP7 from Fairchild Semiconductor is the primary substitute. This part maintains identical electrical specifications (2.2V, 20mA, 150mcd) and mechanical configuration (5mm T-1 3/4 through-hole right-angle) as the obsolete onsemi original. Product status is active with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory compliance.

Functional Alternatives (Circuit Design Adaptation Required):

HLMP-D105 and HLMP-D105-M0002 (Broadcom Limited) operate at lower forward voltage (1.8V) with higher brightness output (240mcd). These parts require circuit redesign to accommodate the voltage differential but provide superior optical performance. Both are ROHS3 compliant and REACH unaffected.

LTL2R3KEK and LTL2R3KRK (Lite-On Inc.) operate within the 2.0-2.05V range with significantly higher brightness (680-700mcd). These parts are compatible with existing circuit designs and offer enhanced visibility. LTL2R3KRK carries REACH affected status; verify regulatory requirements before selection.

OVLLR8C7 (TT Electronics/Optek Technology) operates at 2.0V with 900mcd brightness and 100° viewing angle. This part is suitable for applications requiring wide-angle visibility and is ROHS3 compliant with REACH unaffected status.

Not Recommended for Direct Substitution:

4302H1-12V and 4302H1-5V (VCC) operate at significantly higher voltages (12V and 5V respectively) with substantially lower brightness (8mcd). These parts require complete circuit redesign and are suitable only for applications with different voltage supply architectures.

HLMP-D155-F0002 (Broadcom Limited) operates at 1mA test current with 10mcd brightness, making it unsuitable for standard 20mA circuit board indicator applications.

Frequently Asked Questions (FAQ)

Q: Can MV37509MP7 be directly replaced with MV37509MP6?

A: Both parts are obsolete onsemi products with identical specifications. MV37509MP6 provides direct compatibility but offers no supply advantage due to obsolete status. The Fairchild Semiconductor MV37509MP7 is the recommended active alternative.

Q: What is the primary difference between the onsemi MV37509MP7 and Broadcom HLMP-D105?

A: Forward voltage differs (2.2V vs. 1.8V) and brightness is higher in the HLMP-D105 (240mcd vs. 150mcd). Circuit redesign is required to accommodate the lower voltage requirement, but the part is electrically compatible within standard LED circuit topologies.

Q: Are Lite-On LTL2R3KEK and LTL2R3KRK interchangeable with MV37509MP7?

A: Both Lite-On parts operate within compatible voltage ranges (2.0-2.05V) and maintain 20mA current rating. They are mechanically and electrically compatible with existing MV37509MP7 circuit designs. LTL2R3KEK offers higher brightness (700mcd) with REACH unaffected status; LTL2R3KRK carries REACH affected designation.

Q: Why do 4302H1-12V and 4302H1-5V require circuit redesign?

A: These VCC parts operate at 12V and 5V forward voltages respectively, compared to 2.2V for the MV37509MP7. Direct substitution would cause LED failure or require series resistor modification. Additionally, brightness output (8mcd) is substantially lower than the original specification (150mcd).

Q: What packaging options are available for substitute parts?

A: Most substitute parts are available in bulk packaging. HLMP-D105-M0002 and HLMP-D155-F0002 are supplied in Tape & Reel format for automated assembly. Verify packaging requirements with procurement specifications before final part selection.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitute parts carry ROHS3 compliance. REACH status varies: most are REACH unaffected; LTL2R3KRK is REACH affected. Verify regulatory requirements for your specific application and region.

Q: Which substitute offers the widest viewing angle?

A: OVLLR8C7 provides 100° viewing angle compared to 24-30° for other alternatives and unspecified angle for the original MV37509MP7. This part is suitable for applications requiring wide-angle visibility.

Q: Can brightness differences affect circuit board indicator visibility?

A: Yes. The original MV37509MP7 delivers 150mcd. Alternatives range from 8mcd (HLMP-D155-F0002, 4302H1 series) to 900mcd (OVLLR8C7). Higher brightness may require optical diffusion or reduced current to prevent over-illumination. Lower brightness may require circuit optimization or lens selection review.
