Engineering Selection Recommendations
All substitute parts maintain identical electrical specifications and compliance certifications. Selection between SFML-115-T2-SM-D and its equivalents is based on:
Termination and Fastening Designation: The T2 designation indicates a specific termination style, while 02 represents an alternative termination approach. Both are functionally equivalent for electrical performance. The SM designation denotes a specific fastening mechanism, while S denotes an alternative fastening approach.
Optional Features: Parts designated with -LC suffix include Board Lock functionality. Parts designated with -A suffix include Board Guide functionality. These features provide mechanical retention enhancements but do not alter electrical ratings or operating parameters.
Product Status and Compliance: All parts maintain Active product status and ROHS3 compliance. SFML-115-T2-S-D-LC offers the highest current inventory at 3811 units, providing supply chain flexibility.
Interchangeability: All listed substitute parts are electrically and mechanically interchangeable within the SFML-115 base product family when core parameters remain constant.
Frequently Asked Questions (FAQ)
Q: Can SFML-115-T2-SM-D be directly replaced with SFML-115-02-S-D?
A: Yes. Both parts share identical electrical ratings (3.2A per contact, 250VAC), operating temperature range (-55°C ~ 125°C), and mechanical configuration (30 positions, 0.050" pitch, 2 rows). The difference in designation reflects alternative termination and fastening styles that do not affect functional compatibility.
Q: What is the difference between parts with -LC suffix and those without?
A: The -LC suffix indicates Board Lock feature inclusion. This provides mechanical retention enhancement but does not change electrical performance, current rating, voltage rating, or operating temperature specifications.
Q: Are SFML-115-T2-S-D-A and SFML-115-T2-S-D-LC interchangeable?
A: Both parts are electrically equivalent with identical ratings and operating parameters. SFML-115-T2-S-D-A includes Board Guide functionality, while SFML-115-T2-S-D-LC includes Board Lock functionality. Selection depends on mechanical retention requirements for the specific application.
Q: Does the termination style designation (T2 vs. 02) affect PCB layout or footprint?
A: No. All substitute parts within the SFML-115 family maintain identical pitch (0.050"), row spacing (0.050"), and mounting type (Surface Mount). PCB footprint compatibility is preserved across all listed equivalents.
Q: Which substitute part offers the best inventory availability?
A: SFML-115-T2-S-D-LC maintains the highest inventory level at 3811 units, providing optimal supply chain availability while maintaining full electrical and mechanical equivalence to SFML-115-T2-SM-D.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance and UL94 V-0 material flammability rating, consistent with the main part specification.
