Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors in the SFM series is determined by strict equivalence across the following critical parameters:

• Connector configuration: 36-position receptacle with 2-row layout
• Pitch specification: 0.050" (1.27mm) mating pitch and row spacing
• Electrical ratings: 3.2A per contact, 250VAC minimum
• Surface mount termination: Solder attachment method
• Contact material and finish: Beryllium copper with gold mating surface (10.0µin thickness)
• Operating environment: -55°C to 125°C temperature range, UL94 V-0 flammability rating
• Compliance: RoHS3 and MSL 1 certification

The SFM-118-02-L-D-A-N qualifies as a direct substitute based on identical values across all critical parameters. The addition of board guide features in the substitute part represents a functional enhancement that does not compromise compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-118-T2-L-D and SFM-118-02-L-D-A-N maintain Active product status from Samtec Inc., ensuring continued manufacturing support and supply availability. Both parts carry identical RoHS3 compliance and MSL 1 certification, meeting regulatory requirements for industrial and commercial applications without moisture sensitivity constraints.

The SFM-118-02-L-D-A-N includes board guide features as an enhancement. This addition does not alter electrical performance, current capacity, voltage rating, or thermal operating range. The board guide provides mechanical alignment assistance during assembly without affecting mating compatibility or contact integrity.

Selection between these parts depends on assembly process requirements. If board guide alignment features provide manufacturing or assembly benefits, the SFM-118-02-L-D-A-N is the appropriate choice. If board guide features are not required, either part satisfies the electrical and mechanical specifications identically.

Frequently Asked Questions (FAQ)

Q: Are SFM-118-T2-L-D and SFM-118-02-L-D-A-N electrically interchangeable?

A: Yes. Both connectors provide identical electrical performance: 36-position receptacle configuration, 0.050" (1.27mm) pitch, 3.2A per contact rating, and 250VAC voltage rating. Contact material, finish thickness, and operating temperature range are identical.

Q: What is the difference between these two part numbers?
