Equivalent & Substitute Parts for MV64521 Green LED T-1 3/4 Through Hole

Part Overview

The MV64521 is an active green LED indicator from Everlight Electronics Co Ltd, designed for discrete indication applications in through-hole mounting configurations. This T-1 3/4 (5mm) radial LED operates at 2.2V forward voltage with a 100mcd brightness rating and clear lens transparency. The component is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and consumer electronics applications. Substitute parts are identified to address application requirements where alternative voltage ratings or optical characteristics are necessary while maintaining mechanical and electrical compatibility within the T-1 3/4 form factor.

Substitute Part Grouping Explanation

Substitute parts for the MV64521 are identified from the Visual Communications Company (VCC) 4302H5 series based on the following substitution criteria:

Maintained Parameters (Substitution Basis):

• Color: Green (all parts)
• Lens Style: Round with Domed Top (all parts)
• Lens Size: 5mm, T-1 3/4 (all parts)
• Mounting Type: Through Hole (all parts)
• Package / Case: Radial (all parts)
• RoHS Status: ROHS3 Compliant (all parts)
• Product Status: Active (all parts)

Variable Parameters (Application-Dependent Selection):

• Voltage - Forward (Vf): 2.2V (MV64521) vs. 5V (4302H5-5V) vs. 12V (4302H5-12V)
• Lens Transparency: Clear (MV64521) vs. Diffused (4302H5 series)
• Millicandela Rating: 100mcd (MV64521) vs. 8mcd (4302H5 series)
• Viewing Angle: 35° (MV64521) vs. 60° (4302H5 series)
• Current - Test: 20mA (MV64521) vs. 12-13mA (4302H5 series)
• Height (Max): 8.89mm (MV64521) vs. 10.08mm (4302H5 series)

The 4302H5-5V and 4302H5-12V parts are electrically and mechanically compatible within the T-1 3/4 through-hole form factor. Selection between these substitutes depends on circuit voltage requirements and optical performance needs.

Parameter Comparison

Engineering Selection Recommendations

MV64521 (Primary Selection): Select the MV64521 when circuit design specifies 2.2V forward voltage operation with 20mA test current. This part delivers 100mcd brightness with a 35° viewing angle and clear lens transparency, suitable for direct indication applications requiring high luminous intensity in a focused beam pattern. ROHS3 compliance and MSL 1 rating support standard manufacturing and storage conditions.

4302H5-5V (Substitute for 5V Systems): The 4302H5-5V is mechanically and electrically compatible for applications requiring 5V forward voltage operation. This part operates at 12mA test current with 8mcd brightness and diffused lens transparency, providing wider 60° viewing angle distribution. Height increases to 10.08mm; verify PCB layout clearance. ROHS3 compliance and MSL 1 rating maintained. Select when circuit voltage is fixed at 5V and optical diffusion is acceptable.

4302H5-12V (Substitute for 12V Systems): The 4302H5-12V is mechanically and electrically compatible for applications requiring 12V forward voltage operation. This part operates at 13mA test current with 8mcd brightness and diffused lens transparency, providing 60° viewing angle. Height increases to 10.08mm; verify PCB layout clearance. ROHS3 compliance and MSL 1 rating maintained. Select when circuit voltage is fixed at 12V and optical diffusion is acceptable.

All substitute parts maintain active product status and full regulatory compliance. Selection is determined by circuit voltage requirements and optical performance specifications.

Frequently Asked Questions (FAQ)

Q: Can the 4302H5-5V or 4302H5-12V directly replace the MV64521 in existing designs?

A: Direct replacement requires circuit voltage compatibility. The MV64521 operates at 2.2V; the 4302H5-5V requires 5V; the 4302H5-12V requires 12V. Mechanical compatibility exists within the T-1 3/4 through-hole form factor, but electrical circuit redesign is necessary if voltage differs from the original specification.

Q: What is the impact of lens transparency differences?

A: The MV64521 features a clear lens providing focused light output at 35° viewing angle with 100mcd brightness. The 4302H5 series features diffused lenses providing dispersed light output at 60° viewing angle with 8mcd brightness. Clear lenses concentrate light intensity; diffused lenses distribute light over a wider area. Application requirements determine which transparency is appropriate.

Q: Are there height differences that affect PCB layout?

A: Yes. The MV64521 has a maximum height of 8.89mm. Both 4302H5-5V and 4302H5-12V have a maximum height of 10.08mm. Verify PCB clearance and component spacing before substitution, particularly in space-constrained designs.

Q: Do all parts meet the same compliance standards?

A: Yes. The MV64521, 4302H5-5V, and 4302H5-12V are all ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating. All parts maintain active product status. Regulatory compliance is consistent across all three options.

Q: What is the wavelength difference between parts?

A: The MV64521 has a peak wavelength of 562nm. Both 4302H5-5V and 4302H5-12V have a peak wavelength of 565nm. This 3nm difference is within the green spectrum and represents a negligible shift in perceived color for indication applications.

Q: How do current ratings differ?

A: The MV64521 operates at 20mA test current. The 4302H5-5V operates at 12mA test current. The 4302H5-12V operates at 13mA test current. Lower test currents in the 4302H5 series reflect the higher forward voltage operation and different optical design. Circuit current-limiting resistor values must be recalculated for each part based on supply voltage and forward voltage specifications.
