Physical height (6.35mm maximum; 6.10mm alternatives acceptable)

Substitute Categories:

Parametric Equivalent (Same Voltage): 4302F5-5V - Same manufacturer, identical mechanical and optical specifications, different voltage rating for 5V circuit applications.
Similar Alternatives (Different Voltage/Current): TLLG4400, TLLG4400-AS12, TLLG4401, TLLG4401-AS12 (Vishay) - Lower forward voltage (1.9V), reduced test current (2mA), lower brightness (1.2-2mcd), narrower viewing angle (50°).
Similar Alternatives (Different Voltage/Current): WP710A10SGD, WP710A10SGD5V (Kingbright) - Higher forward voltage options (2.2V or 5V), higher brightness (25-40mcd), narrower viewing angle (40°).

All substitute parts maintain T-1 (3mm) through-hole radial package format, green diffused lens configuration, and compliance certifications.

Engineering Selection Recommendations

For Direct Replacement (Same Circuit Voltage):

The 4302F5-5V serves as a parametric equivalent when circuit redesign to 5V operation is acceptable. Both parts are manufactured by VCC, maintain identical mechanical dimensions and optical characteristics, and carry equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between 12V and 5V variants depends solely on circuit voltage requirements.

For Alternative Voltage Applications:

Vishay TLLG4400 series (TLLG4400, TLLG4400-AS12) and TLLG4401 series (TLLG4401, TLLG4401-AS12) operate at 1.9V forward voltage with reduced test current (2mA). These parts are suitable for low-voltage indicator applications but provide lower brightness (1.2-2mcd versus 8mcd) and narrower viewing angle (50° versus 60°). Packaging options include bulk and cut tape (CT) formats.

Kingbright WP710A10SGD and WP710A10SGD5V provide higher brightness alternatives (40mcd and 25mcd respectively) with narrower viewing angles (40°). The WP710A10SGD5V operates at 5V and provides intermediate brightness between the VCC 4302F5-5V and the higher-output WP710A10SGD variant.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance and REACH unaffected status. All parts are currently active in production with confirmed inventory availability. Selection should prioritize parts with highest inventory levels for supply chain continuity: TLLG4401-AS12 (10,803 pcs), TLLG4401 (6,643 pcs), and TLLG4400 (6,028 pcs).

Frequently Asked Questions (FAQ)

Q: Can the 4302F5-12V be replaced with the 4302F5-5V in the same circuit?

A: No. The 4302F5-5V requires a 5V power supply versus the 12V requirement of the 4302F5-12V. Circuit redesign is necessary to accommodate the different forward voltage. Both parts are otherwise identical in mechanical and optical specifications.

Q: What is the difference between TLLG4400 and TLLG4401?

A: Both parts operate at 1.9V forward voltage with 2mA test current and 50° viewing angle. The primary difference is millicandela rating: TLLG4400 provides 1.2mcd while TLLG4401 provides 2mcd. TLLG4400-AS12 and TLLG4401-AS12 are cut tape packaged variants of the same parts.

Q: Are the Kingbright WP710A10SGD and WP710A10SGD5V interchangeable?

A: No. The WP710A10SGD operates at 2.2V forward voltage with 40mcd brightness, while the WP710A10SGD5V operates at 5V with 25mcd brightness. Circuit voltage requirements determine which variant is appropriate.

Q: What is the viewing angle difference between the 4302F5-12V and Vishay alternatives?

A: The 4302F5-12V provides a 60° viewing angle, while Vishay TLLG4400 and TLLG4401 series provide 50° viewing angles. The narrower angle concentrates light output in a smaller cone, suitable for directed indication applications.

Q: Can I use a higher brightness LED (WP710A10SGD at 40mcd) as a substitute for the 4302F5-12V (8mcd)?

A: Brightness substitution is possible only if circuit current limiting is adjusted. The WP710A10SGD requires 20mA test current versus 13mA for the 4302F5-12V. Resistor values in the current-limiting circuit must be recalculated to accommodate the different forward voltage (2.2V) and current requirements.

Q: What packaging formats are available for these green T-1 LEDs?

A: VCC and Kingbright parts are supplied in bulk packaging. Vishay TLLG4400 and TLLG4401 series are available in both bulk and cut tape (CT) formats. Cut tape packaging is suitable for automated pick-and-place assembly processes.

Q: Are all these parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and REACH unaffected status, meeting current environmental and hazardous substance regulations.

Q: What is the maximum height difference between these parts?

A: The 4302F5-12V has a maximum height of 6.35mm. Vishay parts (TLLG4400/TLLG4401 series) have a maximum height of 6.10mm. Kingbright parts (WP710 series) have a maximum height of 5.90mm. These differences are within typical PCB layout tolerances for through-hole components.
