Parameter Comparison

Engineering Selection Recommendations

Both the SSF-LXH4RASRD and SSF-LXH103SRD are active products manufactured by Lumex Opto/Components Inc. and maintain full compliance with ROHS3 and REACH regulatory requirements. Both components carry Moisture Sensitivity Level 1 classification, indicating unlimited shelf life under standard storage conditions.

The SSF-LXH103SRD functions as a direct substitute for the SSF-LXH4RASRD in circuit board indicator applications. The 0.1V voltage rating difference (1.8V versus 1.7V) does not affect circuit compatibility, as both values operate within the standard forward voltage range for red LEDs and are accommodated by typical series resistor calculations in indicator circuits.

Component selection between these two parts may be based on inventory availability, packaging requirements, or supply chain considerations. The SSF-LXH103SRD is available in bulk packaging with higher inventory levels (3603 pieces), while the SSF-LXH4RASRD maintains active status with 782 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can SSF-LXH103SRD replace SSF-LXH4RASRD in existing circuit designs?

A: Yes. Both parts are electrically and mechanically equivalent for circuit board indicator applications. The voltage rating difference of 0.1V is within acceptable tolerance for LED indicator circuits and does not require circuit redesign.

Q: Are there differences in optical performance between these parts?

A: No. Both parts deliver identical optical specifications: 80 millicandela brightness, 60-degree viewing angle, 660nm peak wavelength, and diffused red lens characteristics.

Q: What is the significance of the voltage rating difference?

A: The SSF-LXH4RASRD operates at 1.7V forward voltage, while the SSF-LXH103SRD operates at 1.8V. This 0.1V difference is typical variation within the red LED category and does not affect circuit functionality when using standard series resistor current-limiting designs.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both SSF-LXH4RASRD and SSF-LXH103SRD are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference in packaging between these parts?

A: The SSF-LXH4RASRD is supplied in standard packaging, while the SSF-LXH103SRD is available in bulk packaging. Packaging selection depends on procurement volume and assembly requirements.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts carry Moisture Sensitivity Level 1 classification, indicating unlimited shelf life and no special moisture control requirements during storage or handling.

Q: Can these parts be used interchangeably in production?

A: Yes. Both parts maintain identical mechanical mounting characteristics (through-hole, right-angle, 3mm T-1 form factor) and electrical specifications for LED indicator applications, supporting direct substitution in manufacturing processes.
