Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MV6951 is determined by the following criteria:

Mechanical Compatibility:

• Lens size: 5mm, T-1 3/4 package
• Mounting type: Through hole radial configuration
• Lens style: Round with domed top
• Lens color: Red
• Lens transparency: Diffused

Optical Compatibility:

• Color: Red indication
• Wavelength range: Peak wavelength in the red spectrum (635nm–650nm acceptable)
• Millicandela rating: Minimum 8mcd for indication applications

Electrical Compatibility:

• Forward voltage (Vf): Determined by circuit design; substitutes available at 2.4V, 5V, and 12V ratings
• Test current: 10mA–20mA range
• Configuration: Standard, single LED

Compliance & Environmental:

• RoHS3 compliance required
• Moisture sensitivity level: MSL 1 (Unlimited)

The substitute parts 4302H1-5V and 4302H1-12V from Visual Communications Company (VCC) meet all mechanical and optical criteria. Electrical parameter differences (forward voltage and test current) reflect design variants for different circuit applications rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

MV6951 (Everlight Electronics Co Ltd):

• Primary selection for 2.4V circuit applications
• Highest millicandela rating (12mcd) among the group
• Widest viewing angle (70°)
• Lowest maximum height (8.89mm)
• Active product status with adequate inventory (907 units)
• ROHS3 compliant

4302H1-5V (Visual Communications Company - VCC):

• Selection for 5V circuit applications
• Mechanical compatibility with MV6951 confirmed
• Higher maximum height (10.08mm) requires PCB layout verification
• Active product status with higher inventory availability (2640 units)
• ROHS3 compliant with REACH unaffected status

4302H1-12V (Visual Communications Company - VCC):

• Selection for 12V circuit applications
• Mechanical compatibility with MV6951 confirmed
• Higher maximum height (10.08mm) requires PCB layout verification
• Active product status with good inventory availability (1927 units)
• ROHS3 compliant with REACH unaffected status

All three parts satisfy RoHS3 compliance and MSL 1 environmental requirements. Selection is determined by circuit voltage requirements and PCB height constraints.

Frequently Asked Questions (FAQ)

Q: Can 4302H1-5V or 4302H1-12V be used as direct replacements for MV6951 in the same circuit?

A: Direct replacement depends on circuit voltage design. The MV6951 operates at 2.4V forward voltage, while 4302H1-5V requires 5V and 4302H1-12V requires 12V. Each part is designed for its specified voltage rating. Substitution is valid only when the circuit voltage matches the LED's forward voltage specification.

Q: What are the mechanical differences between MV6951 and the VCC substitutes?

A: All three parts use identical 5mm T-1 3/4 through-hole radial packages with round domed-top lenses. The primary mechanical difference is maximum height: MV6951 is 8.89mm, while both VCC parts are 10.08mm. This 1.19mm difference must be verified against PCB layout and enclosure clearance requirements.

Q: Are there optical performance differences?

A: Yes. MV6951 provides 12mcd brightness with a 70° viewing angle. Both VCC substitutes provide 8mcd with 60° viewing angles. The MV6951 is brighter with a wider viewing angle. Peak wavelengths differ slightly (MV6951: 650nm; VCC parts: 635nm), both within the red spectrum for indication applications.

Q: Are all parts RoHS3 compliant?

A: Yes. MV6951, 4302H1-5V, and 4302H1-12V are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Which part should be selected for new designs?

A: Selection is based on circuit voltage requirements. For 2.4V circuits, use MV6951. For 5V circuits, use 4302H1-5V. For 12V circuits, use 4302H1-12V. All are active products with adequate inventory and full compliance certifications.

Q: What is the significance of the 1.19mm height difference?

A: The height difference between MV6951 (8.89mm) and VCC parts (10.08mm) affects PCB layout and enclosure design. Verify clearance in applications with tight vertical space constraints or specific mechanical requirements.
