Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFM-118-02-L-D is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 36 positions in 2-row configuration
• Pitch Specifications: 0.050" (1.27mm) mating pitch and row spacing
• Mounting Technology: Surface mount termination with solder connection
• 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 (10.0µin thickness)

Substitute parts must maintain identical values across all listed parameters to ensure direct interchangeability without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

Both SFM-118-02-L-D and SFM-118-02-L-D-A-N maintain Active product status with full ROHS3 compliance and UL94 V-0 certification. All critical electrical, mechanical, and environmental parameters are identical between the two parts. The SFM-118-02-L-D-A-N variant includes a board guide feature, which provides additional mechanical alignment during assembly but does not alter the core connector functionality or electrical performance.

Selection between these parts depends on PCB design requirements. If board-level alignment guidance is beneficial for manufacturing processes, the SFM-118-02-L-D-A-N is appropriate. If the board guide is not required or conflicts with existing PCB layout, the SFM-118-02-L-D remains fully compatible. Both parts are suitable for direct substitution in applications requiring 36-position 0.050" pitch surface mount receptacle connectors with gold contacts and 3.2A per contact current capacity.

Frequently Asked Questions (FAQ)

Q: Can SFM-118-02-L-D and SFM-118-02-L-D-A-N be used interchangeably?

A: Yes. Both parts share identical electrical ratings, contact configurations, pitch specifications, and environmental compliance. The only difference is the board guide feature on the SFM-118-02-L-D-A-N variant. Interchangeability depends on whether the PCB layout accommodates or requires the board guide.
