Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical equivalence to the SFM-105-01-SM-D. Selection among these alternatives is determined by application-specific feature requirements and inventory availability:

SFM-105-01-S-D is electrically and mechanically equivalent with no additional features. This part carries MSL 1 (Unlimited) rating and REACH Unaffected status.

SFM-105-01-S-D-A includes Board Guide feature for enhanced mechanical alignment during mating. This variant carries MSL 1 (Unlimited) rating and REACH Unaffected status.

SFM-105-01-S-D-LC includes Board Lock feature for positive mechanical retention after mating. This variant carries MSL 1 (Unlimited) rating and REACH Unaffected status.

SFM-105-L1-S-D-LC combines Board Lock feature with alternative internal configuration. This variant carries MSL Not Applicable rating.

SFM-105-T1-S-D-A includes Board Guide feature with alternative internal configuration. This variant carries MSL Not Applicable rating and REACH Unaffected status.

All parts are Active in production status and ROHS3 Compliant. Selection should account for specific mechanical retention or alignment requirements of the application, as well as moisture sensitivity constraints if applicable.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts maintain identical electrical and mechanical parameters including connector type, contact configuration, pitch, current rating, voltage rating, operating temperature range, and material specifications. The primary difference is the absence of additional features in the SFM-105-01-S-D variant.

Q: What is the difference between Board Guide and Board Lock features?

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

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, meeting regulatory requirements for restricted substances.

Q: What does MSL (Moisture Sensitivity Level) indicate?

A: MSL indicates the connector's sensitivity to moisture absorption during storage and handling. MSL 1 (Unlimited) indicates no moisture sensitivity restrictions. MSL Not Applicable indicates the part does not require moisture sensitivity classification. Both ratings are acceptable for standard applications; selection depends on storage and handling protocols specific to your supply chain.

Q: Can these connectors be used interchangeably in the same PCB design?

A: Yes, provided the PCB footprint accommodates the specific feature set. Parts with Board Guide or Board Lock features require corresponding PCB cutouts or slots. Verify mechanical compatibility with your PCB layout before substitution.

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

A: All substitute parts support identical mated stacking heights: 6.02mm, 6.17mm, 7.80mm, 7.95mm, 9.58mm, 9.73mm, 11.48mm, and 11.63mm. Selection depends on your application's vertical space constraints.

Q: Are all substitute parts available in the same packaging?

A: Yes. All substitute parts are supplied in Tube packaging, consistent with the main part SFM-105-01-SM-D.
