LED GREEN DIFFUSED T-1 3/4 T/H 4302H5-12V Equivalent & Substitute Parts

Part Overview

The 4302H5-12V is an active green LED indicator manufactured by Visual Communications Company (VCC), designed for through-hole mounting applications requiring 12V forward voltage operation. This discrete radial LED provides green indication with diffused lens characteristics suitable for general indication purposes. The part is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial applications. Substitute parts are identified to address inventory availability, voltage requirement variations, or application-specific design modifications while maintaining functional equivalence within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4302H5-12V is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Lens size: 5mm, T-1 3/4 (fixed requirement)
• Mounting type: Through Hole (fixed requirement)
• Package configuration: Radial (fixed requirement)
• Physical height: 10.08mm maximum (fixed requirement)
• Lens style: Round with domed top (fixed requirement)

Optical Parameters:

• Color: Green (fixed requirement)
• Lens transparency: Diffused (fixed requirement)
• Wavelength - Peak: 565nm (fixed requirement)
• Viewing angle: 60° (fixed requirement)
• Millicandela rating: 8mcd (fixed requirement)

Electrical Parameters (Variable):

• Voltage - Forward (Vf): May vary based on application design
• Current - Test: May vary within acceptable operating range

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (required)
• Moisture Sensitivity Level: 1 (Unlimited) (required)
• REACH Status: REACH Unaffected (required)
• Product Status: Active (required)

The 4302H5-5V qualifies as a parametric equivalent substitute based on identical mechanical, optical, and compliance specifications. The primary difference is forward voltage rating (5V versus 12V), which represents a design variation for different circuit voltage requirements rather than a functional degradation.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (4302H5-12V): The 4302H5-12V is the specified component for applications requiring 12V forward voltage operation. This part maintains active product status with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection is appropriate for designs operating at 12V supply voltage with circuit current limiting to 13mA test specification.

Substitute Part Selection (4302H5-5V): The 4302H5-5V serves as a parametric equivalent for applications requiring 5V forward voltage operation. This substitute maintains identical mechanical form factor, optical characteristics, and compliance certifications. Current-test specification is 12mA, representing a 1mA reduction from the main part. Selection is appropriate for designs operating at 5V supply voltage with corresponding circuit current limiting.

Compliance Basis: Both parts maintain ROHS3 compliance, unlimited MSL rating, and REACH unaffected status, ensuring regulatory equivalence for standard industrial and commercial applications. Product status is active for both variants, confirming ongoing manufacturing support and availability.

Frequently Asked Questions (FAQ)

Q: Can the 4302H5-5V be used in a circuit designed for the 4302H5-12V?

A: No. The 4302H5-5V operates at 5V forward voltage, while the 4302H5-12V requires 12V. Direct substitution without circuit redesign will result in incorrect LED operation or failure. The supply voltage and current-limiting resistor values must be recalculated for the 5V variant.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical mechanical specifications: 5mm T-1 3/4 lens size, 10.08mm maximum height, radial through-hole package configuration, and round domed-top lens style. They are mechanically interchangeable at the PCB level.

Q: What is the difference in test current between these parts?

A: The 4302H5-12V specifies 13mA test current, while the 4302H5-5V specifies 12mA test current. This 1mA difference reflects the electrical characteristics of each variant and must be considered in circuit current-limiting calculations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 4302H5-12V and 4302H5-5V are ROHS3 compliant, REACH unaffected, and maintain MSL 1 (unlimited) moisture sensitivity rating. They are equivalent from a regulatory and environmental compliance perspective.

Q: Can these parts be used interchangeably in the same PCB design?

A: No. While mechanically identical, the different forward voltage ratings require different circuit designs. The supply voltage and current-limiting resistor must be selected based on the specific part number used. PCB layout can be identical, but circuit schematic and component values must be voltage-specific.

Q: What is the optical output difference between these parts?

A: Both parts deliver identical optical characteristics: 8mcd brightness, 565nm peak wavelength, 60° viewing angle, green color, and diffused lens transparency. Optical performance is equivalent regardless of voltage rating.

Q: Are both parts currently in production?

A: Yes. Both the 4302H5-12V and 4302H5-5V maintain active product status with Visual Communications Company (VCC), confirming ongoing manufacturing and availability.
