Engineering Selection Recommendations

The SML-LX15IC-RP-TR is the direct active equivalent for the obsolete SSL-LX15IC-RP-TR. Selection of this substitute is supported by the following factors:

Product Status: The substitute part maintains active production status, ensuring long-term supply chain availability and continued manufacturer support, whereas the main part is classified as obsolete.

Regulatory Compliance: Both components maintain identical RoHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements for electronic component procurement.

Electrical Performance: Identical forward voltage (2V), test current (20mA), peak wavelength (635nm), viewing angle (140°), and millicandela rating (10mcd) ensure functional equivalence in circuit applications.

Mechanical Compatibility: Both components utilize the SOT-23 package family with surface mount configuration. The substitute exhibits a maximum height of 1.00mm compared to 1.05mm for the main part, representing a negligible dimensional variance that does not impact PCB layout or assembly processes.

Moisture Sensitivity: The substitute part carries MSL 3 (168 hours) compared to MSL 4 (72 hours) for the main part, indicating improved moisture tolerance during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the SML-LX15IC-RP-TR directly replace the SSL-LX15IC-RP-TR in existing designs?

A: Yes. Both components share identical electrical specifications (2V forward voltage, 20mA test current, 635nm peak wavelength, 10mcd rating, 140° viewing angle) and are housed in compatible SOT-23 package variants. The substitute maintains the same lens characteristics (clear, colorless, rectangular flat-top design) and mounting type (surface mount).

Q: What is the significance of the product status difference?

A: The SSL-LX15IC-RP-TR is classified as obsolete, indicating discontinued production and limited remaining inventory. The SML-LX15IC-RP-TR maintains active status, ensuring continued availability from the manufacturer and supporting long-term supply chain requirements for production and field replacements.

Q: Are there dimensional differences between these parts?

A: The maximum height differs by 0.05mm (SSL-LX15IC-RP-TR: 1.05mm; SML-LX15IC-RP-TR: 1.00mm). The lens dimensions vary (SSL-LX15IC-RP-TR: 3.00mm L x 1.50mm W; SML-LX15IC-RP-TR: 2.00mm x 3.00mm), but both maintain rectangular flat-top geometry. These dimensional variations do not impact PCB assembly or circuit functionality.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, satisfying current environmental regulations. Both carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: What is the difference in moisture sensitivity levels?

A: The SML-LX15IC-RP-TR carries MSL 3 (168 hours), providing superior moisture tolerance compared to the SSL-LX15IC-RP-TR at MSL 4 (72 hours). This represents an improvement in component robustness during storage and handling operations.

Q: Are packaging options different between these parts?

A: The SSL-LX15IC-RP-TR is supplied in standard packaging, while the SML-LX15IC-RP-TR is available in Tape & Reel (TR) format, which is standard for high-volume surface mount production environments.
