Substitute Part Grouping Explanation

Substitute parts for the SSL-LXA228ID-TR21 are identified based on strict parametric equivalence across the following critical criteria:

Electrical Parameters: Forward voltage (2V), test current (20mA), millicandela rating (12mcd), peak wavelength (635nm), and viewing angle (50°) must remain identical.

Optical Parameters: Color (red), lens transparency (diffused), lens style (round with domed top), and lens size (1.90mm diameter) must be preserved.

Mechanical Parameters: Mounting type (surface mount, bottom entry), package configuration (2-SMD, yoke bend), physical dimensions (2.50mm L x 2.00mm W, 2.90mm max height), and base product number (SSL-LXA228) must align.

Compliance Parameters: RoHS3 compliance and MSL rating (4, 72 hours) must be maintained.

The primary distinction among equivalent parts within the SSL-LXA228 family relates to the supplier device package designation, which affects the specific mounting interface while preserving all functional and electrical characteristics.

Engineering Selection Recommendations

The SSL-LXA228LID-TR21 is the primary substitute for the obsolete SSL-LXA228ID-TR21. Both components are manufactured by Lumex Opto/Components Inc. and share identical electrical, optical, and mechanical specifications across all critical parameters.

The SSL-LXA228LID-TR21 holds active product status, ensuring current availability and ongoing manufacturer support. Both parts maintain ROHS3 compliance and identical MSL ratings, satisfying regulatory and environmental requirements.

The distinction between these parts is limited to the supplier device package designation: the main part uses an axial package interface, while the substitute uses a yoke lead package interface. This difference affects the mounting interface configuration but does not alter functional performance, electrical characteristics, or physical dimensions.

Selection of the SSL-LXA228LID-TR21 as a substitute is appropriate for applications requiring equivalent optical output, forward voltage, current characteristics, and compliance certifications. PCB layout and mounting fixture modifications may be necessary to accommodate the yoke lead package interface.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between SSL-LXA228ID-TR21 and SSL-LXA228LID-TR21?

A: The primary difference is the supplier device package designation. The SSL-LXA228ID-TR21 uses an axial package interface, while the SSL-LXA228LID-TR21 uses a yoke lead package interface. All electrical, optical, and mechanical specifications are identical.

Q: Are these parts electrically interchangeable?

A: Yes. Both parts deliver identical forward voltage (2V), test current (20mA), millicandela rating (12mcd), peak wavelength (635nm), and viewing angle (50°). Electrical performance is equivalent.

Q: Will the SSL-LXA228LID-TR21 fit existing PCB designs for the SSL-LXA228ID-TR21?

A: The physical dimensions and height are identical (2.50mm L x 2.00mm W, 2.90mm max height). However, the yoke lead package interface differs from the axial package interface. PCB footprint and mounting fixture modifications are required.

Q: Are both parts RoHS compliant?

A: Yes. Both SSL-LXA228ID-TR21 and SSL-LXA228LID-TR21 are ROHS3 compliant and carry identical MSL ratings (4, 72 hours).

Q: Why is the SSL-LXA228ID-TR21 listed as obsolete?

A: The SSL-LXA228ID-TR21 is classified as obsolete by the manufacturer. The SSL-LXA228LID-TR21 maintains active product status and is the recommended substitute for ongoing applications.

Q: Can I use the SSL-LXA228LID-TR21 in new designs?

A: Yes. The SSL-LXA228LID-TR21 is an active product with current manufacturer support and is suitable for new design implementations requiring equivalent optical and electrical specifications.
