3GCL-F LED Green Clear T-1 Equivalent & Substitute Parts

Part Overview

The 3GCL-F is a green LED indication component manufactured by Bivar Inc., designed for discrete 2.1V radial through-hole applications. This part carries an Obsolete product status, necessitating identification of active substitute components to maintain design compatibility and ensure continued supply chain availability. The component is a standard T-1 (3mm) form factor LED with clear lens transparency and 4mcd brightness rating, suitable for visual indication circuits requiring green wavelength output.

Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the 3GCL-F is based on the following core electrical and mechanical compatibility parameters:

Primary Compatibility Criteria:

• Color and Wavelength: Green wavelength output (Peak wavelength range 565-568nm)
• Form Factor and Package: T-1 (3mm) through-hole radial configuration
• Forward Voltage (Vf): 1.9V to 2.1V range, within standard LED forward voltage tolerance
• Test Current: 2mA nominal operation
• Mounting Type: Through-hole radial configuration
• Physical Dimensions: 3mm lens diameter with compatible height profiles (5.55-5.90mm)
• Lens Style: Round with domed top geometry
• Viewing Angle: Wide viewing characteristics (20-40°) suitable for indication applications

The WP710A10LGD substitute meets all primary mechanical and electrical compatibility requirements for direct replacement in the 3GCL-F application circuit.

Parameter Comparison

Engineering Selection Recommendations

The WP710A10LGD (Kingbright) is an active production substitute for the obsolete 3GCL-F. Selection between these components is determined by the specific application requirements and available inventory status:

Original Part (3GCL-F): Obsolete status with 1109 pieces available in inventory. No longer in active production.

Substitute Part (WP710A10LGD): Active product status with 26374 pieces available in inventory. RoHS3 Compliant and REACH Unaffected. Suitable for new designs and production requirements where supply chain continuity is critical.

The WP710A10LGD exhibits electrical compatibility within standard LED operating parameters. The forward voltage difference of 0.2V falls within typical circuit tolerance levels for LED indication applications. The expanded viewing angle (40° versus 20°) and diffused lens transparency provide wider light distribution characteristics compared to the original clear lens design.

Frequently Asked Questions (FAQ)

Q: Can the WP710A10LGD directly replace the 3GCL-F without circuit modifications? A: Yes, for standard indication applications. Both components operate at 2mA test current and exhibit compatible forward voltage characteristics (2.1V versus 1.9V). The 0.2V difference is within normal LED circuit tolerance. Through-hole radial configuration is identical.

Q: What are the key differences between the original and substitute? A: Primary differences are lens transparency (clear versus diffused), brightness rating (4mcd versus 2mcd), viewing angle (20° versus 40°), and product status (obsolete versus active). Physical dimensions are nearly identical (3.00mm versus 2.90mm diameter; 5.55mm versus 5.90mm height).

Q: How does the diffused lens of the substitute compare to the clear lens of the original? A: The diffused lens on the WP710A10LGD provides broader light distribution (40° viewing angle) compared to the 20° viewing angle of the original clear lens design. This affects brightness perception across wider observation angles but may appear dimmer when viewed directly on-axis due to the diffusing material.

Q: Are both parts RoHS compliant? A: The WP710A10LGD is RoHS3 Compliant and REACH Unaffected. The original 3GCL-F does not list explicit RoHS compliance in the provided specifications.

Q: Is the 2mcd brightness rating of the substitute sufficient if the original is 4mcd? A: Brightness adequacy depends on the specific application circuit design, viewing distance, and ambient light conditions. The substitute's diffused lens distributes light across a wider angle (40° versus 20°), which may affect perceived brightness in directed indication applications.

Q: What are the package and mounting considerations? A: Both components use T-1 (3mm) through-hole radial configuration suitable for standard PCB mounting. Physical dimensions are nearly identical, allowing direct mechanical compatibility in existing PCB footprints.
