Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFM-112-02-SM-D is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 24 positions in 2-row configuration
• Pitch Specifications: 0.050" (1.27mm) mating pitch and row spacing
• Mounting Technology: Surface mount solder termination
• Electrical Performance: 3.2A per contact at 250VAC minimum
• Environmental Compliance: ROHS3 compliance and UL94 V-0 flammability rating
• Operating Range: -55°C to 125°C temperature specification
• Contact Material & Finish: Beryllium copper with gold mating surface and tin post finish

The substitute part SFM-112-02-S-D-A maintains identical specifications across all critical parameters, with the addition of a board guide feature that does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both SFM-112-02-SM-D and SFM-112-02-S-D-A are Active status products from Samtec Inc. and maintain full ROHS3 compliance with UL94 V-0 flammability certification. Selection between these parts should be based on mechanical design requirements:

The SFM-112-02-SM-D is the baseline receptacle connector suitable for applications where standard surface mount assembly is sufficient.

The SFM-112-02-S-D-A includes a board guide feature, providing enhanced mechanical alignment during mating operations. This feature does not alter electrical performance, current rating, voltage rating, or thermal operating range. Both parts share identical contact geometry, pitch specifications, and environmental ratings.

Current inventory levels support both options: SFM-112-02-SM-D (907 pcs) and SFM-112-02-S-D-A (923 pcs).

Frequently Asked Questions (FAQ)

Q: Are SFM-112-02-SM-D and SFM-112-02-S-D-A electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications: 3.2A per contact, 250VAC rating, beryllium copper contacts with gold mating finish, and -55°C to 125°C operating temperature range.

Q: What is the functional difference between these two parts?

A: The SFM-112-02-S-D-A includes a board guide feature for improved mechanical alignment during connector mating. This is a mechanical enhancement that does not affect electrical performance or contact integrity.

Q: Can I substitute SFM-112-02-S-D-A for SFM-112-02-SM-D in existing designs?

A: Direct substitution is possible from an electrical and thermal standpoint. However, PCB layout must accommodate the board guide feature of the SFM-112-02-S-D-A. Verify mechanical clearance and mounting hole alignment with your specific board design.
