Substitute Part Grouping Explanation

Substitution within the SFM-125 series is determined by electrical and mechanical compatibility across the following critical parameters:

  • 50-position receptacle configuration with 0.050" (1.27mm) pitch mating
  • 2-row arrangement with 0.050" (1.27mm) row spacing
  • Surface mount solder termination with push-pull fastening
  • 3.2A per contact current rating and 250VAC voltage rating
  • Gold-plated female socket contacts with beryllium copper material
  • Operating temperature range of -55°C ~ 125°C
  • UL94 V-0 flammability rating and ROHS3 compliance

The substitute part SFM-125-02-S-D-A-P maintains identical specifications across all electrical and mechanical parameters, differing only in internal design revision coding. Both parts are manufactured by Samtec Inc. within the active Tiger Eye™ SFM series and are fully interchangeable for applications requiring these specifications.

Engineering Selection Recommendations

Both SFM-125-T2-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. Selection between these parts should be based on procurement availability and design documentation requirements. The SFM-125-T2-S-D-A-P currently maintains higher inventory levels (994 pcs) compared to SFM-125-02-S-D-A-P (909 pcs). Both parts are suitable for applications requiring 50-position surface mount receptacle connectors with 0.050" pitch and 3.2A per contact current capacity. No electrical or mechanical performance differentiation exists between these part numbers.

Frequently Asked Questions (FAQ)

Q: Are SFM-125-T2-S-D-A-P and SFM-125-02-S-D-A-P electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 3.2A per contact current rating, 250VAC voltage rating, and gold-plated beryllium copper contact construction. They are fully interchangeable in applications designed for either part number.

Q: What determines compatibility between these connector part numbers?

A: Compatibility is determined by matching the following parameters: 50-position receptacle configuration, 0.050" (1.27mm) mating pitch, 2-row arrangement, surface mount solder termination, push-pull fastening, and operating temperature range of -55°C ~ 125°C. Both parts satisfy all these requirements.

Q: Do these parts have different mechanical footprints?

A: No. Both parts share identical mechanical specifications including insulation height of 0.185" (4.70mm), mated stacking heights (6.15mm through 11.76mm), and surface mount package dimensions. PCB layout and assembly processes are identical.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both SFM-125-T2-S-D-A-P and SFM-125-02-S-D-A-P are ROHS3 compliant with UL94 V-0 flammability rating and Moisture Sensitivity Level 1 (unlimited shelf life). Both are active production parts suitable for current design implementations.

Q: What is the difference between these part numbers?

A: The difference lies in internal design revision coding (T2 versus 02). This represents a manufacturing or design iteration within the same product family. All functional, electrical, and mechanical specifications remain identical.
