Substitute Part Grouping Explanation

Substitution eligibility for the SFM-120-T2-S-D-LC-P is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 40 positions in 2-row configuration
• 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 minimum
• Environmental Compliance: Operating temperature range -55°C ~ 125°C, UL94 V-0 flammability, RoHS3 compliance
• Contact Materials & Finish: Beryllium copper contacts with gold mating finish and tin post finish
• Insulation Material: Liquid Crystal Polymer (LCP)

The substitute part SFM-120-02-S-D-LC-P meets all these criteria, differing only in internal design variant designation (02 vs. T2) while maintaining identical electrical, mechanical, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-120-T2-S-D-LC-P and SFM-120-02-S-D-LC-P maintain Active product status with identical compliance certifications, including RoHS3 compliance and UL94 V-0 flammability rating. The SFM-120-02-S-D-LC-P offers current inventory availability of 828 pieces, compared to 1066 pieces for the primary part number. Selection between these parts should be based on immediate supply requirements and design documentation specifications. Both parts satisfy identical electrical, mechanical, and environmental performance criteria for 40-position, 0.050" pitch surface mount receptacle applications.

Frequently Asked Questions (FAQ)

Q: Can SFM-120-02-S-D-LC-P be used as a direct replacement for SFM-120-T2-S-D-LC-P?

A: Yes. Both parts are electrically and mechanically equivalent receptacle connectors with identical 40-position, 0.050" pitch configurations, contact ratings, operating temperatures, and compliance certifications. The designation difference (T2 vs. 02) represents internal design variants within the same product family with no functional distinction.

Q: Are the mated stacking heights identical between these parts?

A: Yes. Both parts support the same mated stacking height options: 6.15mm, 6.30mm, 7.92mm, 8.08mm, 9.70mm, 9.86mm, 11.61mm, and 11.76mm.

Q: Do both parts meet the same compliance and certification requirements?

A: Yes. Both parts are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity ratings. They share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the current rating per contact for these connectors?

A: Both parts are rated for 3.2A per contact at 250VAC, with operating temperature range of -55°C to 125°C.

Q: Are the contact materials and finishes the same?

A: Yes. Both parts use beryllium copper contacts with 30.0µin (0.76µm) gold mating finish and tin post finish.

Q: Can these parts be used interchangeably in pick-and-place assembly?

A: Yes. Both parts feature identical board lock and pick-and-place capabilities, with matching insulation height of 0.185" (4.70mm) and surface mount termination specifications.
