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

Part Overview

The TFC-125-22-L-D is a Samtec Tiger Eye™ TFC series rectangular connector header designed for surface mount board-to-board or cable applications. This shrouded 4-wall header features 50 positions arranged in 2 rows with 0.050" (1.27mm) pitch and mating spacing. The connector is actively produced and stocked, with full position loading and solder termination via push-pull fastening. Substitute parts within this series are identified based on matching electrical specifications and core mechanical parameters while accommodating variations in insulation height and board guide features.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFC-125-22-L-D, TFC-125-12-L-D-A, and TFC-125-32-L-D-A—are active products from Samtec Inc. with ROHS3 compliance and identical electrical ratings. Selection between these parts is determined by PCB layout requirements and available vertical clearance.

TFC-125-22-L-D provides a mid-range insulation height of 0.366" (9.30mm) without board guide features, suitable for standard board-to-board spacing applications.

TFC-125-12-L-D-A features the lowest insulation height at 0.296" (7.52mm) with integrated board guide, appropriate for space-constrained designs requiring additional mechanical alignment.

TFC-125-32-L-D-A offers the highest insulation height at 0.441" (11.20mm) with board guide features, suitable for applications requiring increased vertical clearance or enhanced mechanical stability.

All parts maintain identical contact ratings, voltage specifications, operating temperature ranges, and flammability certifications. Substitution is valid when PCB layout accommodates the respective insulation height and when board guide presence or absence does not conflict with design requirements.

Frequently Asked Questions (FAQ)

Q: Can TFC-125-12-L-D-A replace TFC-125-22-L-D in my design?

A: Yes, if your PCB layout accommodates the reduced insulation height of 0.296" (7.52mm) compared to the original 0.366" (9.30mm). The board guide feature on the substitute part provides additional mechanical alignment and does not create compatibility issues. All electrical specifications remain identical.

Q: What is the primary difference between these three parts?

A: The three parts differ in insulation height and board guide configuration. TFC-125-22-L-D has no board guide and 0.366" height. TFC-125-12-L-D-A has a board guide and reduced height of 0.296". TFC-125-32-L-D-A has a board guide and increased height of 0.441". All other mechanical and electrical parameters are identical.

Q: Are the substitute parts electrically equivalent to the main part?

A: Yes. All three parts share identical contact ratings (3.1A per Contact), voltage ratings (275VAC), operating temperature ranges (-55°C ~ 125°C), contact materials (Phosphor Bronze), contact finishes (Gold mating, Tin post), and insulation materials (Liquid Crystal Polymer). They are electrically interchangeable.

Q: Do the substitute parts have the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant, UL94 V-0 rated, and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Moisture sensitivity level is 1 (Unlimited) for all parts.

Q: Which part should I choose if space is limited?

A: If vertical clearance is constrained, TFC-125-12-L-D-A with its 0.296" insulation height is the appropriate choice. If additional clearance is available and preferred, TFC-125-32-L-D-A at 0.441" height provides enhanced mechanical stability through its board guide feature.

Q: Are there inventory differences between these parts?

A: Yes. Current stock levels are: TFC-125-22-L-D (1104 pcs), TFC-125-12-L-D-A (919 pcs), and TFC-125-32-L-D-A (820 pcs). Availability may vary; verify current inventory status with your supplier.
