Substitute Part Grouping Explanation

The SFML-120-T2-S-D-K qualifies as a direct substitute for the SFML-120-T2-S-D-P based on identical electrical and mechanical parameters. Substitution is determined by the following critical parameters:

  • Connector type (Receptacle) and contact type (Female Socket)
  • Position count (40) and pitch specification (0.050" / 1.27mm)
  • Row configuration (2 rows with 0.050" row spacing)
  • Mounting method (Surface Mount) and termination type (Solder)
  • Electrical ratings (3.2A per contact, 250VAC)
  • Operating temperature range (-55°C ~ 125°C)
  • Contact finish specification (Gold mating surface)
  • Compliance certifications (ROHS3, UL94 V-0)

Both parts belong to the same Tiger Eye™ SFML series and share identical base product number SFML-120, confirming functional equivalence.

Engineering Selection Recommendations

Both the SFML-120-T2-S-D-P and SFML-120-T2-S-D-K are active production parts with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on inventory availability and supply chain requirements. The SFML-120-T2-S-D-K currently has higher stock levels (1097 units versus 921 units), which may provide supply chain advantages for high-volume production runs. Both parts meet identical electrical, mechanical, and environmental specifications and are suitable for direct substitution in applications requiring 40-position, 0.050" pitch surface mount receptacle connectors.

Frequently Asked Questions (FAQ)

Q: Can SFML-120-T2-S-D-K be used as a direct replacement for SFML-120-T2-S-D-P?

A: Yes. Both parts are functionally equivalent receptacle connectors with identical position count (40), pitch (0.050"), electrical ratings (3.2A per contact, 250VAC), operating temperature range (-55°C ~ 125°C), and compliance certifications (ROHS3, UL94 V-0).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by connector type, contact type, position count, mating pitch, row configuration, row spacing, mounting method, termination type, electrical ratings, operating temperature range, contact finish specification, and compliance certifications. All these parameters must match between the main part and substitute.

Q: Are there any packaging or handling differences between these parts?

A: Both parts are supplied in tube packaging with Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: What is the difference between the part number suffixes -P and -K?

A: The provided data does not specify the technical distinction between the -P and -K suffixes. Both parts share identical electrical, mechanical, and environmental specifications and are classified as direct substitutes within the Tiger Eye™ SFML series.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: Yes, provided the PCB footprint and mating connector are designed for 0.050" pitch, 40-position, 2-row surface mount receptacles. The identical mechanical dimensions and contact specifications ensure mechanical and electrical compatibility.
