LED WHITE CLEAR T/H THW3801C Equivalent & Substitute Parts

Part Overview

The THW3801C is a white LED indication component manufactured by Stanley Electric Co, designed for through-hole mounting applications. This discrete radial LED operates at a forward voltage of 2.9V with a test current of 5mA, delivering 1600mcd brightness in a 3mm T-1 package with clear colorless lens and round domed top configuration. The product is currently classified as obsolete, making identification of compatible substitute components essential for ongoing design support and production continuity.

Engineering Selection Recommendations

The INL-3AW30 from Inolux is a direct substitute for the obsolete THW3801C. Selection is based on the following engineering criteria:

Product Status Alignment: The THW3801C is classified as obsolete, while the INL-3AW30 maintains active product status with current manufacturing support and documented availability of 2659 pieces in stock.

Regulatory Compliance: Both components share identical REACH Status (REACH Unaffected) and ECCN classification (EAR99), ensuring equivalent regulatory standing for export and supply chain applications.

RoHS Compliance: The INL-3AW30 is ROHS3 compliant, meeting current environmental and hazardous substance restrictions applicable to electronic components.

Mechanical and Optical Equivalence: The substitute part maintains identical lens specifications (3mm T-1, round domed top, colorless clear), mounting configuration (through-hole radial), and color (white), ensuring direct physical and functional compatibility in existing PCB layouts and mechanical assemblies.

Electrical Performance: The forward voltage differential (2.9V to 3.1V) and increased test current capability (5mA to 20mA) are within acceptable operating ranges for standard LED indication circuits. The higher millicandela rating (8500mcd versus 1600mcd) provides enhanced brightness margin without requiring circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the INL-3AW30 be used as a direct replacement for THW3801C in existing designs?

A: Yes. The INL-3AW30 is mechanically and optically equivalent, with identical lens size (3mm T-1), mounting type (through-hole radial), and color specifications (white, colorless clear). Both components share the same REACH and ECCN classifications.

Q: What is the voltage difference between these components?

A: The THW3801C operates at 2.9V forward voltage, while the INL-3AW30 operates at 3.1V. This 0.2V difference is within standard tolerance for LED indication circuits and does not require circuit modification.

Q: How do the brightness levels compare?

A: The THW3801C delivers 1600mcd, while the INL-3AW30 delivers 8500mcd. The substitute provides significantly higher brightness, which is compatible with existing designs and may improve visibility in the application.

Q: Are there differences in viewing angle?

A: The THW3801C has a 40° viewing angle, while the INL-3AW30 has a 30° viewing angle. The narrower viewing angle of the substitute may be advantageous in applications requiring more directional light output.

Q: What is the physical height difference?

A: The THW3801C has a maximum height of 5.90mm, while the INL-3AW30 has a maximum height of 5.08mm. The substitute is slightly shorter and will fit within existing mechanical clearance specifications.

Q: Is the INL-3AW30 currently available?

A: Yes. The INL-3AW30 is classified as active product status with 2659 pieces documented in stock, providing reliable supply continuity compared to the obsolete THW3801C.

Q: Do both components meet the same regulatory requirements?

A: Yes. Both the THW3801C and INL-3AW30 share identical REACH Status (REACH Unaffected) and ECCN classification (EAR99). The INL-3AW30 additionally meets ROHS3 compliance requirements.
