Substitute Part Grouping Explanation

Substitute parts for the TFML-126-02-S-D are identified based on strict electrical and mechanical parameter alignment. The critical parameters determining substitution eligibility are:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 52
• 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
• Fastening Type: Friction Lock
• Termination: Solder
• 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

Parts meeting all these criteria are classified as direct substitutes. Variations in non-critical features such as Board Lock functionality do not affect core electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both TFML-126-02-S-D and TFML-126-02-S-D-LC are Active status products from Samtec Inc. and maintain full ROHS3 compliance. The primary distinction is the Board Lock feature present in the TFML-126-02-S-D-LC variant, which provides enhanced mechanical retention during mating cycles. All other electrical and mechanical parameters are identical, including operating temperature range, contact materials, and flammability ratings. Selection between these parts should be based on application requirements for mechanical retention and board-level assembly procedures. Both parts are suitable for direct substitution in applications where the core connector specifications are the determining factor.

Frequently Asked Questions (FAQ)

Q: Can TFML-126-02-S-D-LC replace TFML-126-02-S-D in existing designs?

A: Yes. The TFML-126-02-S-D-LC is a direct substitute for TFML-126-02-S-D. All critical electrical and mechanical parameters are identical, including pitch, number of positions, contact materials, and operating temperature range. The Board Lock feature in the -LC variant is an enhancement that does not affect core compatibility.

Q: What is the significance of the Board Lock feature in TFML-126-02-S-D-LC?

A: Board Lock is a mechanical retention feature that provides additional stability during connector mating and unmating cycles. This feature does not alter electrical performance or physical footprint compatibility.

Q: Are both parts suitable for the same PCB layout and assembly process?

A: Yes. Both TFML-126-02-S-D and TFML-126-02-S-D-LC share identical surface mount footprints, solder termination requirements, and assembly specifications. PCB layouts designed for one part are compatible with the other.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across -55°C to 125°C, meeting requirements for industrial and commercial applications.

Q: Are these connectors RoHS compliant?

A: Yes. Both TFML-126-02-S-D and TFML-126-02-S-D-LC are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What contact material is used in these connectors?

A: Both parts use phosphor bronze contacts with gold mating finish (30.0µin thickness) and tin post finish, providing reliable electrical conductivity and corrosion resistance.
