Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 4302F5-5V is determined by the following critical parameters:

Primary Substitution Criteria:

• Forward voltage (Vf) matching or functional equivalence within circuit design constraints
• Lens size and form factor (T-1, 3mm through-hole radial)
• Color and wavelength (green, 565nm peak)
• Lens transparency (diffused)
• Mounting type (through-hole radial)
• Compliance certifications (ROHS3, REACH Unaffected)

Secondary Compatibility Factors:

• Millicandela rating (brightness level)
• Viewing angle
• Physical height dimensions
• Test current specifications

Substitute parts are grouped into two categories based on forward voltage characteristics:

Category A: Direct 5V Voltage Match Parts with 5V forward voltage specification matching the 4302F5-5V primary operating voltage.

Category B: Alternative Voltage Specifications Parts with different forward voltage ratings (1.9V, 12V) that require circuit design consideration but maintain mechanical and optical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (5V Forward Voltage Category):

SSL-LX3044GD-5V (Lumex Opto/Components Inc.) operates at identical 5V forward voltage with matching 60° viewing angle and green diffused lens specification. This part maintains ROHS3 compliance and REACH unaffected status. Physical height is reduced to 4.60mm compared to 6.35mm of the 4302F5-5V, which may provide space advantages in compact designs. Millicandela rating of 6mcd is lower than the 8mcd of the main part, representing a 25% reduction in brightness output.

WP710A10SGD5V (Kingbright) operates at 5V forward voltage with ROHS3 compliance. This part delivers 25mcd brightness, representing a 212% increase over the 4302F5-5V. Viewing angle is narrower at 40° compared to 60°. Test current is 11.5mA, slightly elevated from the 10mA specification of the main part. Physical height is 5.90mm.

Alternative Voltage Category (1.9V Forward Voltage):

TLLG4401 and TLLG4401-AS12 (Vishay Semiconductor Opto Division) operate at 1.9V forward voltage with 2mcd brightness and 50° viewing angle. These parts require circuit design modification to accommodate the lower forward voltage. TLLG4401-AS12 is supplied in Cut Tape (CT) packaging versus bulk. Both maintain ROHS3 compliance.

TLLG4400 and TLLG4400-AS12 (Vishay Semiconductor Opto Division) operate at 1.9V forward voltage with reduced 1.2mcd brightness and 50° viewing angle. These parts are suitable only for applications where lower brightness is acceptable and circuit design accommodates 1.9V forward voltage operation.

Alternative Voltage Category (12V Forward Voltage):

SSL-LX3044GD-12V (Lumex Opto/Components Inc.) operates at 12V forward voltage, requiring circuit design modification for higher voltage systems. This part maintains 60° viewing angle matching the main part and delivers 6mcd brightness. Physical height is 4.60mm. ROHS3 compliance is maintained.

All substitute parts listed maintain active product status and ROHS3 compliance with REACH unaffected designation, ensuring regulatory alignment with the 4302F5-5V.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX3044GD-5V directly replace 4302F5-5V without circuit modification?

A: SSL-LX3044GD-5V operates at identical 5V forward voltage and maintains matching 60° viewing angle and green diffused lens specification. Direct substitution is mechanically and electrically compatible. The 25% reduction in brightness (6mcd versus 8mcd) must be evaluated against application requirements for light intensity.

Q: What is the primary difference between TLLG4401 and TLLG4400?

A: Both parts operate at 1.9V forward voltage and are supplied by Vishay Semiconductor Opto Division. The primary difference is millicandela rating: TLLG4401 delivers 2mcd brightness while TLLG4400 delivers 1.2mcd brightness. Both require circuit design modification to accommodate 1.9V forward voltage operation compared to the 5V specification of 4302F5-5V.

Q: What packaging options are available for Vishay TLLG series parts?

A: Vishay TLLG series parts are available in two packaging formats: Bulk (standard packaging) and Cut Tape (CT) with 12-piece tape configuration. TLLG4401 and TLLG4400 are available in both formats. The -AS12 suffix designates Cut Tape packaging. Bulk packaging is suitable for high-volume applications, while Cut Tape packaging accommodates automated assembly processes.

Q: How does WP710A10SGD5V brightness compare to 4302F5-5V?

A: WP710A10SGD5V delivers 25mcd brightness compared to 8mcd for 4302F5-5V, representing a 212% increase in light output. This higher brightness is achieved at 5V forward voltage with 11.5mA test current. The narrower 40° viewing angle compared to 60° for the main part concentrates light output in a more focused beam pattern.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed in this reference maintain ROHS3 compliance and REACH unaffected status, matching the regulatory certification of 4302F5-5V. This ensures compliance with environmental and hazardous substance restrictions across all listed alternatives.

Q: What is the significance of the T-1 form factor designation?

A: T-1 designates a 3mm diameter lens form factor for through-hole radial LED packages. All parts in this reference maintain T-1 (3mm) specification, ensuring mechanical compatibility with standard LED mounting footprints and through-hole PCB designs. Physical height variations (4.60mm to 6.35mm) do not affect the T-1 classification.

Q: Can WP710A10SGD (2.2V) be used in a 5V circuit designed for 4302F5-5V?

A: WP710A10SGD operates at 2.2V forward voltage and requires circuit design modification compared to the 5V specification of 4302F5-5V. Direct substitution without circuit redesign is not recommended. The lower forward voltage requires adjustment of current-limiting resistor values to maintain proper operating current and brightness output.

Q: What is the difference between SSL-LX3044GD-5V and SSL-LX3044GD-12V?

A: Both parts are manufactured by Lumex Opto/Components Inc. with identical mechanical specifications (4.60mm height, T-1 form factor, 60° viewing angle, 6mcd brightness). The primary difference is forward voltage: SSL-LX3044GD-5V operates at 5V while SSL-LX3044GD-12V operates at 12V. Selection depends on circuit voltage requirements.
