SSF-LXH4RA5ID LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The SSF-LXH4RA5ID is an active LED Circuit Board Indicator manufactured by Lumex Opto/Components Inc. This component is a single red diffused LED with a 5mm T-1 3/4 form factor, designed for through-hole right-angle mounting on printed circuit boards. The part operates at 2.1V with a 20mA forward current and delivers 30 millicandela brightness at a 60-degree viewing angle. Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits component optimization within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSF-LXH4RA5ID is determined by strict equivalence across the following critical parameters: color (red), wavelength peak (635nm), configuration (single), forward current (20mA), millicandela rating (30mcd), viewing angle (60°), lens type (diffused, tinted), lens style (round with domed top), lens size (5mm T-1 3/4), mounting type (through hole, right angle), and manufacturer (Lumex Opto/Components Inc.). The forward voltage rating may vary within acceptable design tolerances when the substitute part maintains all other electrical and mechanical specifications. Substitute parts must retain active product status and maintain equivalent compliance certifications (RoHS3, REACH Unaffected, MSL 1).

Parameter Comparison

Engineering Selection Recommendations

The SSF-LXH100MID qualifies as a direct substitute for the SSF-LXH4RA5ID based on complete parameter alignment across all critical electrical and mechanical specifications. Both parts are manufactured by Lumex Opto/Components Inc., maintain active product status, and carry identical RoHS3 and REACH compliance certifications. The forward voltage differential of 0.1V (2.1V versus 2.0V) falls within acceptable operating tolerances for LED circuit board indicator applications and does not compromise functional equivalence. Both parts carry MSL 1 rating, indicating unlimited shelf life under standard storage conditions. Selection between these parts may be determined by inventory availability, lead time requirements, or cost optimization within procurement parameters.

Frequently Asked Questions (FAQ)

Q: Can SSF-LXH100MID replace SSF-LXH4RA5ID in existing circuit designs?

A: Yes. The SSF-LXH100MID is electrically and mechanically equivalent to the SSF-LXH4RA5ID. Both parts share identical color, wavelength, current rating, brightness, viewing angle, lens configuration, and mounting type. The 0.1V forward voltage difference does not affect circuit compatibility in standard LED indicator applications.

Q: What is the significance of the forward voltage difference between these parts?

A: The SSF-LXH4RA5ID operates at 2.1V while the SSF-LXH100MID operates at 2.0V. This 0.1V variance is typical within LED manufacturing tolerances and does not impact circuit performance when proper current-limiting resistors are used in the design.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both the SSF-LXH4RA5ID and SSF-LXH100MID are ROHS3 compliant, REACH unaffected, and carry MSL 1 moisture sensitivity rating. Both parts meet equivalent environmental and regulatory requirements.

Q: Do these parts have identical physical dimensions and mounting characteristics?

A: Yes. Both parts feature 5mm T-1 3/4 lens size, round domed top lens style, and through-hole right-angle mounting configuration. Physical dimensions and PCB mounting footprints are identical.

Q: What factors should determine part selection between SSF-LXH4RA5ID and SSF-LXH100MID?

A: Selection should be based on inventory availability, supplier lead times, cost considerations, and procurement requirements. From an engineering standpoint, both parts are functionally equivalent and interchangeable.
