Equivalent & Substitute Parts for MV5477C Green LED T-1 Through Hole

Part Overview

The MV5477C is an active green LED indication component manufactured by Everlight Electronics Co Ltd, designed for through-hole mounting applications. This diffused T-1 LED operates at 2.2V forward voltage with a 7mcd brightness rating and 140° viewing angle, suitable for standard indicator applications requiring green wavelength output at 565nm peak. The component is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified to provide design flexibility, support supply chain continuity, and accommodate specific application requirements such as brightness levels, viewing angles, or dimensional constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MV5477C are qualified based on the following criteria:

Primary Compatibility Requirements:

• Lens Color: Green
• Lens Transparency: Diffused
• Mounting Type: Through Hole
• Package Configuration: Radial (T-1 form factor)
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited)

Secondary Parameters Allowing Variation:

• Forward Voltage (Vf): Range 2.1V to 2.2V acceptable for standard indicator circuits
• Millicandela Rating: 6mcd to 16mcd range accommodates different brightness requirements
• Viewing Angle: 85° to 140° range supports various application geometries
• Wavelength Peak: 565nm to 572nm range within green spectrum
• Height: 4.60mm to 6.00mm accommodates standard through-hole PCB clearances
• Lens Style: Round with Domed Top or Round with Flat Top both acceptable for diffused indicators

The identified substitutes (SLR-332MG3F and WP424GDT) meet all primary compatibility requirements and fall within acceptable ranges for secondary parameters.

Parameter Comparison

Engineering Selection Recommendations

MV5477C (Primary Component) Select this part when Everlight Electronics supply is available and brightness requirement is 7mcd with wide 140° viewing angle. Forward voltage of 2.2V and test current of 20mA establish the baseline circuit design parameters.

SLR-332MG3F (Rohm Semiconductor Substitute) This part is suitable when higher brightness (16mcd) is required for the same application. The 2.1V forward voltage is compatible with standard indicator circuits designed for 2.2V operation. The narrower 85° viewing angle restricts this substitute to applications where directional indication is acceptable. Lower test current (10mA) may reduce power consumption in current-limited circuits. Wavelength shift to 572nm remains within green spectrum perception. Shorter height (4.60mm) accommodates tighter PCB clearance constraints. ROHS3 compliance and MSL 1 rating match primary component specifications.

WP424GDT (Kingbright Substitute) This part provides near-equivalent brightness (6mcd) and identical forward voltage (2.2V) to the primary component. The flat-top lens style differs from the domed-top primary component but maintains diffused optical characteristics. Viewing angle of 100° is narrower than the primary component but wider than the Rohm alternative. Test current matches at 20mA. Greater height (6.00mm) requires verification of PCB clearance in space-constrained designs. Wavelength peak at 565nm matches the primary component exactly. ROHS3 compliance and MSL 1 rating are equivalent.

All three parts are active products with current manufacturing status and full regulatory compliance documentation available.

Frequently Asked Questions (FAQ)

Q: Can SLR-332MG3F replace MV5477C in all applications?

A: SLR-332MG3F is compatible with applications where the narrower 85° viewing angle and higher 16mcd brightness are acceptable. The 2.1V forward voltage operates within standard indicator circuit tolerances. Applications requiring the original 140° wide viewing angle must use MV5477C or WP424GDT.

Q: What is the impact of different test currents (10mA vs 20mA)?

A: Test current specifies the operating condition at which brightness and forward voltage are measured. SLR-332MG3F at 10mA test current will exhibit different brightness characteristics than MV5477C at 20mA. Circuit design must account for actual operating current to ensure proper brightness performance.

Q: Are the wavelength differences (565nm vs 572nm) visually significant?

A: Both wavelengths fall within the green spectrum range. The 7nm difference between 565nm and 572nm is within human color perception tolerance for green indication. Visual appearance will be consistent across all three parts in standard indicator applications.

Q: Can these parts be used interchangeably on existing PCBs?

A: All three parts use radial through-hole T-1 form factor with compatible lead spacing. Physical dimensions vary slightly (height 4.60mm to 6.00mm), requiring verification of PCB clearance. Lens style differences (domed vs flat top) do not affect electrical compatibility but may alter light distribution characteristics.

Q: What are the supply chain considerations for these substitutes?

A: MV5477C has 645 pcs in stock. SLR-332MG3F has 21,942 pcs available. WP424GDT has 24,782 pcs available. Substitute parts offer significantly higher inventory levels for applications with extended lead time requirements.

Q: Are all parts suitable for RoHS3 compliant assemblies?

A: Yes. MV5477C, SLR-332MG3F, and WP424GDT are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting regulatory requirements for restricted substance compliance and standard storage conditions.
