Substitute Part Grouping Explanation

Substitution eligibility for the TFML-120-02-SM-D-A is determined by strict equivalence across the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 40
• 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: Friction Lock
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The identified substitute part TFML-120-02-S-D-A meets all these criteria and is therefore electrically and mechanically interchangeable with the main part.

Parameter Comparison

Engineering Selection Recommendations

Both TFML-120-02-SM-D-A and TFML-120-02-S-D-A are active production parts manufactured by Samtec Inc. with identical electrical and mechanical specifications. Both parts are ROHS3 compliant, carry UL94 V-0 flammability certification, and operate across the -55°C to 125°C temperature range. The parts are functionally equivalent for all board-to-board or cable connection applications requiring 40-position, dual-row, 1.27mm pitch surface mount headers with friction lock fastening.

Selection between these parts may be based on inventory availability. The TFML-120-02-S-D-A currently has higher stock levels (979 units) compared to the TFML-120-02-SM-D-A (723 units), which may influence procurement decisions for high-volume applications or extended lead time mitigation.
