Engineering Selection Recommendations

All listed substitute parts maintain identical electrical performance and mechanical interface specifications. Selection between SFM-105-L1-S-D and its equivalents should be based on:

Feature Requirements: Parts designated with board guide features (SFM-105-01-S-D-A, SFM-105-T1-S-D-A) provide alignment assistance during mating. Parts designated with board lock features (SFM-105-01-S-D-LC, SFM-105-L1-S-D-LC) provide positive retention after mating. The base SFM-105-01-S-D variant includes neither feature.

Compliance & Certification: All parts are ROHS3 compliant and rated UL94 V-0 for material flammability. All parts are active in production status.

Inventory Availability: Current stock levels range from 692 to 1107 units across all qualified substitutes, supporting supply chain flexibility.

Frequently Asked Questions (FAQ)

Q: Can SFM-105-01-S-D be used as a direct replacement for SFM-105-L1-S-D?

A: Yes. Both parts share identical electrical specifications (3.2A per contact, 250VAC), mechanical dimensions (10 positions, 0.050" pitch, 2 rows), and compliance ratings (ROHS3, UL94 V-0). The primary difference is the absence of board lock features on the SFM-105-01-S-D variant.

Q: What is the difference between board guide and board lock features?

A: Board guide features (present in SFM-105-01-S-D-A and SFM-105-T1-S-D-A) provide alignment assistance during connector mating. Board lock features (present in SFM-105-01-S-D-LC and SFM-105-L1-S-D-LC) provide positive retention after mating is complete. Both features are optional and do not affect electrical performance.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed parts use through-hole mounting with solder termination and are compatible with standard PCB assembly processes.

Q: Do moisture sensitivity levels affect substitution eligibility?

A: Moisture sensitivity level variations (Not Applicable vs. 1 Unlimited) do not affect electrical or mechanical compatibility. Selection should follow component handling and storage requirements specified in your manufacturing process.

Q: What is the mated stacking height range for these connectors?

A: All parts support identical mated stacking heights: 6.02mm, 6.17mm, 7.80mm, 7.95mm, 9.58mm, 9.73mm, 11.48mm, and 11.63mm.

Q: Are these parts suitable for high-temperature applications?

A: Yes. All parts are rated for operating temperatures from -55°C to 125°C, supporting industrial and automotive applications within this range.
