Substitute Part Grouping Explanation

Substitution eligibility for the TFM-125-02-L-D-A-P is determined by strict equivalence across the following critical parameters:

• Number of Positions: 50
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Contact Type: Male Pin
• Current Rating: 2.9A per Contact
• Voltage Rating: 275VAC
• Operating Temperature Range: -55°C ~ 125°C
• Series: Tiger Eye™ TFM
• RoHS Status: ROHS3 Compliant

Substitute parts must maintain identical electrical performance, mechanical interface dimensions, and environmental ratings. Variations in fastening type, contact finish options, or packaging format do not affect functional substitutability when all primary parameters remain constant.
