TFC-125-22-L-D-A Equivalent & Substitute Parts

Part Overview

The TFC-125-22-L-D-A is a Samtec Tiger Eye™ TFC series rectangular connector header designed for surface mount applications. This shrouded 4-wall header features 50 positions arranged in 2 rows with 0.050" (1.27mm) pitch, supporting board-to-board or cable connections. The connector is rated for 3.1A per contact at 275VAC and operates across -55°C to 125°C. With active product status and ROHS3 compliance, this component remains in production. Equivalent and substitute parts within the Tiger Eye™ TFC series provide design flexibility when specific insulation height requirements or inventory constraints necessitate alternative configurations.

Substitute Part Grouping Explanation

Substitution within the Tiger Eye™ TFC series is determined by electrical and mechanical compatibility. The primary variable among substitute parts is insulation height, which affects board-level clearance and mating stack height but does not alter electrical performance or contact specifications.

Substitution criteria are based on the following parameters:

• Pitch - Mating: 0.050" (1.27mm) — must remain constant
• Number of Positions: 50 — must remain constant
• Number of Rows: 2 — must remain constant
• Contact Type: Male Pin — must remain constant
• Current Rating: 3.1A per Contact — must remain constant
• Voltage Rating: 275VAC — must remain constant
• Operating Temperature: -55°C ~ 125°C — must remain constant
• Shrouding: Shrouded - 4 Wall — must remain constant
• Mounting Type: Surface Mount — must remain constant
• Termination: Solder — must remain constant
• Contact Material and Finish: Phosphor Bronze with Gold mating surface — must remain constant

The TFC-125-22-L-D-A (insulation height 0.366") can be substituted with TFC-125-12-L-D-A (insulation height 0.296") or TFC-125-32-L-D-A (insulation height 0.441") when board clearance or stacking requirements differ from the original design specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFC-125-22-L-D-A, TFC-125-12-L-D-A, and TFC-125-32-L-D-A—maintain identical electrical specifications and are fully interchangeable from a functional standpoint. Each part is active in production, ROHS3 compliant, and carries UL94 V-0 flammability certification.

Selection between these parts is determined solely by mechanical clearance requirements on the printed circuit board. The insulation height difference ranges from 0.296" (7.52mm) for the TFC-125-12-L-D-A to 0.441" (11.20mm) for the TFC-125-32-L-D-A, with the TFC-125-22-L-D-A positioned at 0.366" (9.30mm) as the mid-range option.

All parts are available in production quantities with current inventory levels supporting immediate procurement.

Frequently Asked Questions (FAQ)

Q: Are TFC-125-22-L-D-A, TFC-125-12-L-D-A, and TFC-125-32-L-D-A electrically identical?

A: Yes. All three parts share identical electrical ratings: 3.1A per contact, 275VAC voltage rating, -55°C to 125°C operating temperature range, and identical contact materials and finishes. They differ only in insulation height.

Q: What determines which substitute part to select?

A: Insulation height is the only variable. Select based on available board clearance above the connector. TFC-125-12-L-D-A requires the least clearance (0.296"), TFC-125-22-L-D-A requires moderate clearance (0.366"), and TFC-125-32-L-D-A requires the most clearance (0.441").

Q: Can these parts be used interchangeably in the same PCB design?

A: No. PCB layout and clearance design must accommodate the specific insulation height of the selected part. Changing from one part to another requires PCB design verification to ensure adequate clearance and proper mating alignment.

Q: Are all three parts ROHS3 compliant?

A: Yes. TFC-125-22-L-D-A, TFC-125-12-L-D-A, and TFC-125-32-L-D-A are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the pitch specification for these connectors?

A: All three parts feature 0.050" (1.27mm) mating pitch with 0.050" (1.27mm) row spacing, supporting 50-position, 2-row configurations.

Q: Are these parts available in production quantities?

A: Yes. Current inventory includes 738 units of TFC-125-22-L-D-A, 919 units of TFC-125-12-L-D-A, and 820 units of TFC-125-32-L-D-A, all new original stock in tube packaging.
