Substitute Part Grouping Explanation

Substitution eligibility for the TFC-125-02-F-D-TR is determined by strict equivalence across the following critical parameters:

  • Connector Type: Header
  • Contact Type: Male Pin
  • Number of Positions: 50
  • Number of Rows: 2
  • Pitch - Mating: 0.050" (1.27mm)
  • Row Spacing - Mating: 0.050" (1.27mm)
  • Mounting Type: Surface Mount
  • Shrouding: Shrouded - 4 Wall
  • Termination: Solder
  • Fastening Type: Push-Pull
  • Contact Finish - Mating: Gold
  • Contact Material: Phosphor Bronze
  • Insulation Material: Liquid Crystal Polymer (LCP)
  • Operating Temperature: -55°C ~ 125°C
  • Current Rating: 3.1A per Contact
  • Voltage Rating: 275VAC
  • Material Flammability Rating: UL94 V-0
  • RoHS Status: ROHS3 Compliant
  • Moisture Sensitivity Level: 1 (Unlimited)

The substitute part TFC-125-02-F-D-A-K-TR maintains full electrical and mechanical compatibility with the main part across all critical parameters. Differences are limited to non-critical features such as board guide and pick-and-place capabilities, which represent functional enhancements rather than substitution barriers.
