Substitute Part Grouping Explanation

Substitution eligibility for the SFM-115-T1-SM-D-LC is determined by strict equivalence across the following critical parameters:

Connector type (Receptacle), contact type (Female Socket), and style (Board to Board or Cable)
Number of positions (30) and row configuration (2 rows)
Mating pitch (0.050" / 1.27mm) and row spacing (0.050" / 1.27mm)
Mounting type (Through Hole) and termination method (Solder)
Fastening mechanism (Push-Pull)
Electrical ratings: 3.2A per contact, 250VAC
Operating temperature range (-55°C ~ 125°C)
Contact materials and finishes (Beryllium Copper with gold mating finish and tin post finish)
Insulation material (Liquid Crystal Polymer) and flammability rating (UL94 V-0)
Compliance certifications (ROHS3)

The identified substitute part SFM-115-01-S-D-LC maintains full equivalence across all these parameters, with the primary distinction being packaging configuration and moisture sensitivity level classification.

Engineering Selection Recommendations

Both the SFM-115-T1-SM-D-LC and SFM-115-01-S-D-LC are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. The parts are electrically and mechanically equivalent across all specified parameters, including connector geometry, contact ratings, operating temperature range, and material composition.

Selection between these parts should be based on procurement availability and inventory status. The SFM-115-T1-SM-D-LC currently maintains higher inventory (1119 units) compared to the SFM-115-01-S-D-LC (976 units). Both parts are suitable for applications requiring 30-position board-to-board or cable connectivity with 0.050" pitch mating contacts and 3.2A per contact current capacity at 250VAC.

Frequently Asked Questions (FAQ)

Q: Are SFM-115-T1-SM-D-LC and SFM-115-01-S-D-LC fully interchangeable?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical connector type, position count, pitch, contact materials, electrical ratings, operating temperature range, and compliance certifications. Both are through-hole solder-terminated receptacles with push-pull fastening in the Tiger Eye™ SFM series.

Q: What is the difference between these two part numbers?

A: The primary difference is the packaging configuration designation within the part number structure. Both parts are supplied in tube packaging and maintain full functional equivalence. Inventory levels differ, with SFM-115-T1-SM-D-LC currently stocked at higher quantities.

Q: Can I use SFM-115-01-S-D-LC as a direct replacement in existing designs?
