Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFM-120-02-SM-D-P is determined by strict equivalence across the following critical parameters:

• Manufacturer: Samtec Inc.
• Series: Tiger Eye™ SFM
• Connector Type: Receptacle
• Number of Positions: 40
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Mounting Type: Surface Mount
• Current Rating: 3.2A per Contact
• Voltage Rating: 250VAC
• Operating Temperature Range: -55°C ~ 125°C
• Contact Finish - Mating: Gold
• RoHS Compliance: ROHS3 Compliant

The substitute part SFM-120-02-S-D-P meets all these criteria and differs only in termination method designation within the same product family, maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both SFM-120-02-SM-D-P and SFM-120-02-S-D-P are active production parts with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and procurement lead times. The SFM-120-02-S-D-P currently has higher inventory (981 Pcs) compared to SFM-120-02-SM-D-P (639 Pcs), which may influence supply chain decisions. Both parts maintain the same performance characteristics, temperature range, current and voltage ratings, and contact finish specifications required for board-to-board or cable interconnect applications.

Frequently Asked Questions (FAQ)

Q: Are SFM-120-02-SM-D-P and SFM-120-02-S-D-P electrically interchangeable?

A: Yes. Both parts are 40-position receptacle connectors with identical electrical ratings (3.2A per contact, 250VAC), operating temperature range (-55°C ~ 125°C), and contact materials (beryllium copper with gold mating finish). They are fully interchangeable in electrical performance.

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

A: The parts differ only in their termination method designation within the part number scheme. All other specifications, including pitch, number of positions, mounting type, and contact configuration, are identical.

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

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

Q: Are both parts RoHS compliant?

A: Yes. Both SFM-120-02-SM-D-P and SFM-120-02-S-D-P are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity).

Q: What is the mating pitch for these connectors?

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

Q: Are these parts suitable for surface mount assembly?

A: Yes. Both parts are surface mount connectors with solder termination and pick-and-place compatibility.
