Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment. Selection among equivalent parts should be based on assembly process requirements and mechanical integration needs:

Parts with Board Guide features (SFM-110-02-S-D-A, SFM-110-02-S-D-A-K, SFM-110-02-S-D-A-P, SFM-110-L2-S-D-A) provide enhanced mechanical alignment during mating operations. Parts with Pick and Place capability (SFM-110-02-L-D-K, SFM-110-02-S-D-A-K, SFM-110-02-S-D-A-P) support automated assembly workflows. Parts with Board Lock features (SFM-110-02-S-D-LC, SFM-110-L2-S-D-LC) provide positive mechanical retention after mating.

SFM-110-02-S-D-SN includes Solder Retention and carries REACH Affected status, requiring compliance verification for applications subject to REACH regulations. All other substitute parts carry REACH Unaffected status or unspecified status.

Mounting style designations (02, L2, T2) represent different physical configurations within the SFM-110 family. Selection should align with specific PCB layout and connector orientation requirements.

Frequently Asked Questions (FAQ)

Q: Can SFM-110-02-SM-D be directly replaced with SFM-110-02-S-D?

A: Yes. Both parts share identical electrical specifications (20 positions, 0.050" pitch, 3.2A per contact, 250VAC, gold-plated contacts) and mechanical dimensions. The primary difference is assembly feature availability; SFM-110-02-S-D does not include optional board guidance or locking mechanisms present in some variants.

Q: What is the difference between mounting styles 02, L2, and T2?

A: Mounting style designations indicate different physical configurations and connector orientations within the SFM-110 base product family. All three styles maintain identical electrical performance and contact specifications. Selection depends on specific PCB layout and mechanical integration requirements.

Q: Are parts with Board Guide features electrically equivalent to the base SFM-110-02-SM-D?

A: Yes. Board Guide features (designated by the "-A" suffix) provide mechanical alignment assistance during mating but do not alter electrical characteristics, contact ratings, or signal integrity. All core electrical parameters remain identical.

Q: Can I use SFM-110-02-S-D-LC as a direct substitute if my application requires positive mechanical retention?

A: Yes. SFM-110-02-S-D-LC includes Board Lock functionality while maintaining all electrical specifications of the SFM-110-02-SM-D. The Board Lock feature provides positive mechanical retention after mating without affecting electrical performance.

Q: What does Pick and Place capability mean for part selection?

A: Pick and Place capability (designated by the "-K" or "-P" suffix) indicates the connector is optimized for automated assembly equipment. These parts maintain identical electrical and mechanical specifications but include design features that facilitate automated placement during manufacturing.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status. SFM-110-02-S-D-SN carries REACH Affected status and requires compliance verification for applications subject to REACH regulations.

Q: Do different mounting styles affect PCB footprint or solder pad layout?

A: Mounting style designations (02, L2, T2) represent different physical configurations. PCB footprint and solder pad layout may differ between styles. Verify mechanical drawings and footprint specifications for the specific mounting style before design implementation.

Q: Can I mix different substitute parts in the same assembly?

A: All substitute parts maintain identical electrical specifications and mating interface dimensions. Physical compatibility depends on specific PCB layout and connector orientation. Verify mechanical compatibility and mounting requirements for your specific application.
