SSL-LX15GC-TR Green LED SOT-23-3 Equivalent & Substitute Parts

Part Overview

The SSL-LX15GC-TR is a surface-mount green LED indicator manufactured by Lumex Opto/Components Inc., housed in a SOT-23-3 package. This component is classified as obsolete product status. The SSL-LX15GC-TR features a clear lens with a rectangular flat-top design, delivering 10 millicandela brightness at 20mA test current with a forward voltage of 2.1V typical and 140° viewing angle. Due to its obsolete classification, equivalent and substitute parts are necessary for ongoing design support and procurement continuity.

Engineering Selection Recommendations

SML-LX15GC-TR (Direct Substitute - Recommended)

The SML-LX15GC-TR is the primary equivalent for the SSL-LX15GC-TR. Both components are manufactured by Lumex Opto/Components Inc. and share identical electrical specifications: 10mcd brightness, 140° viewing angle, 20mA test current, and 565nm peak wavelength. The SML-LX15GC-TR carries active product status, ensuring long-term availability and supply chain continuity. The forward voltage differential of 0.1V (2.2V vs. 2.1V) is within standard LED tolerance ranges for indication applications. The improved moisture sensitivity level (MSL 3 vs. MSL 4) provides enhanced reliability. Package footprint compatibility is confirmed for SOT-23-3 surface-mount applications. ROHS3 compliance and REACH unaffected status are maintained.

XZMG48WA (Similar Substitute - Alternative)

The XZMG48WA manufactured by SunLED provides an alternative substitute option. This component meets the core electrical and mechanical requirements: green color, clear lens, 140° viewing angle, 20mA test current, and 565nm peak wavelength. The millicandela rating of 9mcd represents a 10% reduction from the main part specification, acceptable for standard indication applications where exact brightness matching is not critical. Forward voltage is 2.2V, consistent with the SML-LX15GC-TR. The XZMG48WA maintains active product status, ROHS3 compliance, and MSL 3 moisture sensitivity. Maximum height of 1.20mm is within acceptable PCB assembly tolerances. This substitute is suitable for applications where multi-source component qualification is required.

Frequently Asked Questions (FAQ)

Q: Can the SML-LX15GC-TR directly replace the SSL-LX15GC-TR without circuit modification?

A: Yes. The SML-LX15GC-TR is electrically and mechanically compatible with the SSL-LX15GC-TR. Both components operate at 20mA test current with 140° viewing angle and identical peak wavelength. The forward voltage difference of 0.1V (2.2V vs. 2.1V) is within standard LED operating tolerances and does not require circuit redesign for indication applications.

Q: What is the significance of the MSL rating difference between SSL-LX15GC-TR (MSL 4) and its substitutes (MSL 3)?

A: MSL (Moisture Sensitivity Level) indicates the maximum time a component can be exposed to ambient conditions before soldering. MSL 4 allows 72 hours of exposure, while MSL 3 allows 168 hours. The substitutes offer superior moisture tolerance, reducing risk of component degradation during storage and assembly processes.

Q: Is the 1mcd brightness difference between SML-LX15GC-TR (10mcd) and XZMG48WA (9mcd) significant for LED indication applications?

A: The 10% brightness difference is within acceptable tolerance for standard LED indicator applications. Selection between these parts depends on specific brightness requirements defined in the application circuit design. Both components meet the 140° viewing angle specification for general indication purposes.

Q: Are both substitute parts available in the same packaging format as the original SSL-LX15GC-TR?

A: Yes. Both SML-LX15GC-TR and XZMG48WA are supplied in Tape & Reel (TR) packaging suitable for automated surface-mount assembly. The SOT-23-3 package footprint is identical across all three components, ensuring PCB compatibility without layout modifications.

Q: What compliance certifications apply to the substitute parts?

A: Both SML-LX15GC-TR and XZMG48WA maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original SSL-LX15GC-TR. These certifications ensure suitability for applications requiring environmental and hazardous substance compliance.

Q: Why is the SSL-LX15GC-TR classified as obsolete if substitutes are available?

A: Obsolete classification indicates the manufacturer has discontinued production. Substitute parts with active product status ensure design continuity and long-term supply availability. The SML-LX15GC-TR and XZMG48WA provide equivalent functionality with confirmed ongoing manufacturing support.
