SSL-LX5093XSIC Red LED T-1 3/4 Through Hole Equivalent & Substitute Parts

Part Overview

The SSL-LX5093XSIC is a red LED indication component manufactured by Lumex Opto/Components Inc., designed for through-hole mounting applications. This active product operates at 2V forward voltage with a 2500mcd brightness rating and 636nm peak wavelength, housed in a standard 5mm T-1 3/4 radial package with clear domed lens. The component is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching electrical characteristics, mechanical compatibility, and package specifications. Substitution becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or design flexibility is required across manufacturing locations.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

LTL2R3KRK (Lite-On Inc.) and LTL2R3KEK (Lite-On Inc.) provide the closest electrical match with 2V and 2.05V forward voltage respectively, matching the SSL-LX5093XSIC operating point. Both maintain ROHS3 compliance, unlimited MSL rating, and identical mechanical package specifications. LTL2R3KRK offers 680mcd brightness with 631nm peak wavelength, while LTL2R3KEK provides 700mcd at 624nm. Both are active products with substantial inventory availability.

Secondary Substitutes (Acceptable Compatibility):

OVLLR8C7 (TT Electronics/Optek Technology) operates at 2V with 900mcd brightness and 623nm wavelength, providing higher luminous intensity with wider 100° viewing angle. The flat-top lens style differs from the domed configuration of the primary part. Height specification of 6.80mm is lower than the SSL-LX5093XSIC at 8.60mm, suitable for space-constrained applications.

WP1503EC and WP7113EC (Kingbright) both operate at 2V with 617nm peak wavelength and clear lens transparency. WP1503EC provides 50mcd brightness with 30° viewing angle, while WP7113EC offers 100mcd with 20° viewing angle. Both maintain identical height and ROHS3 compliance.

Conditional Substitutes (Application-Dependent):

HLMP-D105 (Broadcom Limited) operates at 1.8V forward voltage with 240mcd brightness and 637nm wavelength. The lower forward voltage requires circuit verification to ensure proper current limiting. Height of 12.44mm exceeds the primary part specification and may present mechanical clearance concerns in compact layouts.

Not Recommended:

MV3750 (onsemi) carries obsolete product status and is excluded from active substitution consideration despite electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute the SSL-LX5093XSIC with any of these parts without circuit modification?

A: Parts operating at 2V forward voltage (LTL2R3KRK, LTL2R3KEK, OVLLR8C7, WP1503EC, WP7113EC) are direct substitutes requiring no circuit changes. HLMP-D105 operates at 1.8V and requires verification of current-limiting resistor values to maintain 20mA test current.

Q: What is the brightness difference between the SSL-LX5093XSIC and substitute parts?

A: The SSL-LX5093XSIC provides 2500mcd brightness. Substitute parts range from 50mcd (WP1503EC) to 900mcd (OVLLR8C7). Application requirements determine acceptable brightness levels. Lower brightness parts (50-100mcd) are suitable for indicator applications; higher brightness parts (700-900mcd) provide enhanced visibility.

Q: Are all substitute parts ROHS3 compliant?

A: All identified substitute parts carry ROHS3 compliance status, matching the primary part specification. MSL rating of 1 (Unlimited) is consistent across all parts.

Q: Does lens style affect substitution compatibility?

A: Lens style (domed vs. flat-top) affects light distribution and viewing angle but does not prevent mechanical substitution. OVLLR8C7 features a flat-top lens with 100° viewing angle compared to the domed lens design of other parts. Optical performance characteristics differ; application requirements determine acceptability.

Q: What is the height constraint for substitution?

A: The SSL-LX5093XSIC specifies 8.60mm maximum height. OVLLR8C7 is lower at 6.80mm (suitable for compact layouts), while HLMP-D105 is higher at 12.44mm (potential clearance concern). WP1503EC, WP7113EC, and LTL2R3 series match the 8.60-8.70mm specification.

Q: Can I use HLMP-D105 as a direct replacement?

A: HLMP-D105 is electrically compatible but operates at 1.8V versus 2V. Verify current-limiting resistor calculations to maintain proper LED current. The 12.44mm height exceeds the primary part and may require PCB layout verification. All other parameters (package, compliance, MSL) are compatible.

Q: Which substitute offers the best inventory availability?

A: OVLLR8C7 (TT Electronics/Optek Technology) provides the highest inventory with 90,624 pieces in stock. LTL2R3KEK (Lite-On Inc.) offers 9,468 pieces, and HLMP-D105 (Broadcom Limited) provides 8,220 pieces. All three represent substantial supply availability.

Q: Are there wavelength differences between substitute parts?

A: Peak wavelengths range from 627nm (WP1503EC, WP7113EC) to 645nm (HLMP-D105). The SSL-LX5093XSIC operates at 636nm. All wavelengths fall within the red spectrum (617-645nm range) and are visually indistinguishable in typical indicator applications.
