Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFM-140-02-SM-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: 80 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

The substitute part SFM-140-02-S-D-A-P maintains identical specifications across all critical parameters, differing only in internal fastening mechanism designation (S versus SM suffix), which does not affect electrical or mechanical compatibility in board-to-board or cable applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-140-02-SM-D-A-P and SFM-140-02-S-D-A-P maintain Active product status from Samtec Inc., ensuring continued manufacturing support and supply availability. Both parts carry ROHS3 compliance certification and UL94 V-0 flammability rating, meeting regulatory requirements for industrial and commercial applications. The MSL 1 rating on both parts indicates unlimited moisture sensitivity protection, suitable for standard storage and handling conditions without desiccant requirements.

Selection between these two parts should be based on design documentation requirements and assembly process specifications. Both parts are electrically and mechanically equivalent for board-to-board and cable interconnect applications operating within the -55°C to 125°C temperature range at 250VAC and 3.2A per contact ratings.

Frequently Asked Questions (FAQ)

Q: Are SFM-140-02-SM-D-A-P and SFM-140-02-S-D-A-P fully interchangeable?

A: Yes. Both parts are functionally equivalent across all electrical and mechanical parameters. They share identical position counts, pitch specifications, current and voltage ratings, operating temperature range, and contact materials. The suffix difference (SM versus S) does not affect compatibility in applications requiring 80-position, 0.050" pitch receptacle connectors.

Q: What does the suffix difference between SM and S indicate?

A: The suffix designates internal fastening mechanism variants within the Tiger Eye™ SFM series. Both variants maintain identical external dimensions, mating interfaces, and electrical performance specifications.

Q: Can these connectors be used in high-temperature applications?

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

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control measures. These connectors do not require desiccant storage or baking procedures prior to assembly.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SFM-140-02-SM-D-A-P and SFM-140-02-S-D-A-P carry ROHS3 compliance certification, meeting EU Directive 2011/65/EU requirements for restricted substances.

Q: What is the current capacity per contact?

A: Both parts are rated for 3.2A per contact at 250VAC, suitable for moderate-current signal and power distribution applications in board-to-board interconnect configurations.
