Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFM-125-L2-S-D-A-P is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 50 positions in 2-row configuration
• Pitch Specifications: 0.050" (1.27mm) mating pitch and row spacing
• Electrical Ratings: 3.2A per contact at 250VAC minimum
• Mounting Technology: Surface mount solder termination
• Contact Material & Finish: Beryllium copper with gold mating surface (30.0µin minimum)
• Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliance, MSL 1
• Operating Range: -55°C to 125°C temperature specification

The identified substitute SFM-125-02-S-D-A-P maintains all critical electrical and mechanical parameters, differing only in internal design variant designation while preserving functional compatibility within the Tiger Eye™ SFM series.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-125-L2-S-D-A-P and SFM-125-02-S-D-A-P are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. The parts are functionally equivalent across all specified electrical and mechanical parameters, including contact ratings, operating temperature range, and surface mount termination specifications. Selection between these parts may be based on inventory availability or design revision requirements, as both maintain identical performance characteristics within the Tiger Eye™ SFM connector series.

Frequently Asked Questions (FAQ)

Q: Are SFM-125-L2-S-D-A-P and SFM-125-02-S-D-A-P directly interchangeable?

A: Yes. Both connectors are 50-position receptacles with identical pitch (0.050"), contact ratings (3.2A per contact at 250VAC), mounting type (surface mount), and environmental specifications. They are functionally equivalent for board-to-board and cable applications.

Q: What determines if a connector can substitute for the SFM-125-L2-S-D-A-P?

A: Substitutes must maintain: 50-position receptacle configuration, 0.050" (1.27mm) mating pitch, 2-row arrangement with 0.050" row spacing, surface mount solder termination, 3.2A per contact minimum current rating, 250VAC voltage rating, gold-plated female socket contacts, -55°C to 125°C operating range, and ROHS3 compliance with UL94 V-0 flammability rating.

Q: Can I use these connectors in high-temperature applications?

A: Both connectors are rated for -55°C to 125°C operating temperature. Applications requiring operation beyond this range require alternative connector selection.

Q: What is the current handling capacity per contact?

A: Each contact is rated for 3.2A at 250VAC maximum. Total circuit current must account for the number of loaded positions and current distribution across contacts.

Q: Are these connectors RoHS compliant?

A: Yes. Both SFM-125-L2-S-D-A-P and SFM-125-02-S-D-A-P are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level).

Q: What is the pitch specification for these connectors?

A: The mating pitch is 0.050" (1.27mm) with row spacing also at 0.050" (1.27mm) in a 2-row configuration.
