Key Parameters

Substitute Part Grouping Explanation

Substitution of the SFM-104-02-S-D is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Configuration: Receptacle with 8 positions in 2-row arrangement
• Pitch Specifications: 0.050" (1.27mm) mating pitch and row spacing
• Mounting & Termination: Surface mount with solder termination
• Electrical Performance: 3.2A per contact at 250VAC
• Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliance, MSL 1
• Operating Range: -55°C to 125°C temperature specification
• Contact Materials & Finish: Beryllium copper contacts with gold mating finish (30.0µin/0.76µm) and tin post finish

The SFM-104-02-S-D-A qualifies as a direct substitute based on identical electrical, mechanical, and environmental specifications. The only documented difference is the inclusion of a board guide feature in the substitute part, which does not affect electrical compatibility or core functional performance.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-104-02-S-D and SFM-104-02-S-D-A maintain Active product status within the Tiger Eye™ SFM series and carry identical ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on design requirements for mechanical alignment and PCB layout considerations. The SFM-104-02-S-D-A includes a board guide feature that may provide enhanced mechanical stability in applications requiring precise connector positioning. Both parts satisfy identical electrical performance specifications, environmental ratings, and temperature operating ranges. Inventory availability should be evaluated based on procurement timelines, as the SFM-104-02-S-D-A currently maintains higher stock levels (1258 pcs vs. 673 pcs).

Frequently Asked Questions (FAQ)

Q: Are SFM-104-02-S-D and SFM-104-02-S-D-A electrically interchangeable?

A: Yes. Both parts are rated for 3.2A per contact at 250VAC with identical contact materials (beryllium copper), mating finish (gold, 30.0µin), and operating temperature range (-55°C to 125°C). Electrical performance is equivalent.

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

A: The SFM-104-02-S-D-A includes a board guide feature. This is a mechanical enhancement for connector alignment and does not affect electrical compatibility or signal integrity.

Q: Can I substitute SFM-104-02-S-D-A for SFM-104-02-S-D in existing designs?

A: Substitution is mechanically feasible if PCB layout accommodates the board guide feature. Verify footprint compatibility with your design documentation before implementation.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, UL94 V-0 rated, MSL 1, and carry EAR99 export classification. Compliance profiles are identical.

Q: What is the mating pitch specification for these connectors?

A: Both parts feature 0.050" (1.27mm) mating pitch with 0.050" (1.27mm) row spacing in a 2-row configuration.

Q: Are there any temperature or environmental limitations?

A: Both parts operate across -55°C to 125°C with MSL 1 (unlimited moisture sensitivity level), indicating no special storage or handling requirements.
