FA3863X LED Orange Clear 3MM Round T/H Equivalent & Substitute Parts

Part Overview

The FA3863X is an orange 605nm LED indication component manufactured by Stanley Electric Co, configured as a discrete 1.9V radial through-hole device in a 3mm T-1 round domed lens package. This part is classified as obsolete, necessitating identification of functionally equivalent substitute components for ongoing design support and procurement continuity. The 800mcd brightness rating and 40° viewing angle establish the performance baseline for substitute evaluation.

Lens Size: 3mm, T-1 (physical form factor and PCB footprint)
Mounting Type: Through Hole (assembly process compatibility)
Package / Case: Radial (lead configuration)

Secondary Compatibility Parameters:

Voltage - Forward (Vf): Acceptable range 1.9V to 2.1V (circuit design tolerance)
Current - Test: 10mA to 20mA (operating condition flexibility)
Millicandela Rating: 16mcd to 800mcd (brightness variation acceptable based on application)
Viewing Angle: 34° to 85° (optical distribution variation)

Engineering Selection Recommendations

For Direct Orange 605nm Replacement (Preferred):

SLI-343DC3F (Rohm Semiconductor) provides the closest electrical match with identical 1.9V forward voltage and 605nm dominant wavelength. However, this part carries "Not For New Designs" status. For active production designs, SLR-332DC3F or SLR-332DCT32 (both Rohm Semiconductor, Active status) are recommended despite lower brightness (16mcd vs 800mcd), as they maintain 605nm spectral alignment and active product support.

WP710A10SEC and WP710A10SET (Kingbright, Active status) deliver 800mcd brightness matching the original specification with 601nm dominant wavelength and 2.0V forward voltage. These parts accommodate the 0.1V voltage differential within standard circuit design tolerance and maintain identical 5.90mm height and 3mm T-1 form factor.

For Brightness-Critical Applications:

When 800mcd brightness is mandatory, WP710A10SEC or WP710A10SET are the only active substitutes meeting this requirement. The 601nm wavelength represents a 4nm shift from the 605nm specification, acceptable for orange indication applications where spectral precision is not critical.

For Voltage-Sensitive Circuits:

SLI-343DC3F maintains the original 1.9V specification but carries obsolescence status. SLR-332DC3F and SLR-332DCT32 operate at 2.0V, requiring circuit verification for voltage tolerance. HLMP-Y402-G0000 operates at 2.1V, the maximum acceptable deviation.

For Alternative Color Applications:

SLR-332YC3F, SLR-332YCT32 (Rohm, Active), and LTL1CHJSTNN (Lite-On, Active) provide yellow 587nm alternatives where color substitution is permitted. These parts maintain through-hole 3mm T-1 form factor and active product status.

Compliance Status:

All recommended substitutes carry ROHS3 Compliant or RoHS Compliant certification and REACH Unaffected status, matching the original FA3863X compliance profile.

Frequently Asked Questions (FAQ)

Q: Can I use SLR-332DC3F as a direct replacement for FA3863X?

A: SLR-332DC3F maintains the 605nm wavelength and through-hole 3mm T-1 form factor. However, brightness differs significantly (16mcd vs 800mcd), and forward voltage is 2.0V versus 1.9V. Circuit verification is required to confirm voltage tolerance. This part is Active status, supporting ongoing production.

Q: What is the brightness difference between FA3863X and WP710A10SEC?

A: Both parts deliver 800mcd brightness. WP710A10SEC operates at 2.0V forward voltage (0.1V higher than FA3863X) and features 601nm dominant wavelength (4nm shorter than 605nm). The wavelength shift remains within acceptable tolerance for orange indication applications.

Q: Are yellow LED substitutes compatible with orange-specified circuits?

A: Yellow substitutes (SLR-332YC3F, SLR-332YCT32, LTL1CHJSTNN) operate at 587nm wavelength and 2.05V to 2.1V forward voltage. These parts are electrically compatible with circuits designed for 1.9V to 2.1V range but produce yellow indication instead of orange. Use only where application requirements permit color substitution.

Q: What is the difference between SLR-332DCT32 and SLR-332DC3F?

A: Both are Rohm Semiconductor orange LEDs with identical electrical specifications (2.0V, 16mcd, 4.60mm height). SLR-332DCT32 is packaged in Tape & Box (TB) format, while SLR-332DC3F uses Bulk packaging. Viewing angle differs slightly (75° vs 85°). Select based on procurement packaging requirements.

Q: Can I substitute HLMP-Y402-G0000 for FA3863X?

A: HLMP-Y402-G0000 matches the 605nm wavelength and 3mm T-1 form factor but operates at 2.1V forward voltage and delivers only 29mcd brightness. This part is suitable for low-brightness indication applications where the 0.2V voltage increase is acceptable. Circuit verification is required.

Q: Why is SLI-343DC3F marked "Not For New Designs"?

A: SLI-343DC3F carries "Not For New Designs" status, indicating Rohm Semiconductor has transitioned this product to end-of-life. While inventory remains available (2592 pcs), new designs should select Active status alternatives such as SLR-332DC3F or WP710A10SEC to ensure long-term supply continuity.

Q: What packaging options are available for orange 605nm substitutes?

A: SLI-343DC3F and SLR-332DC3F are supplied in Bulk packaging. SLR-332DCT32 is available in Tape & Box (TB) format. WP710A10SEC is Bulk; WP710A10SET packaging is unspecified. Confirm packaging compatibility with procurement and assembly processes before selection.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitutes carry ROHS3 Compliant or RoHS Compliant certification. The original FA3863X is RoHS Compliant. All parts maintain REACH Unaffected status and EAR99 ECCN classification.
