The identified substitute parts TFC-120-22-F-D-A and TFC-120-12-F-D-A maintain all critical electrical and mechanical parameters. Variations in insulation height and the presence of board guide features do not affect functional substitution within the TFC-120 base product family.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFC-120-22-F-D, TFC-120-22-F-D-A, and TFC-120-12-F-D-A—are Active products from Samtec Inc. and maintain full ROHS3 compliance with UL94 V-0 flammability rating. Selection between these parts is based on design-specific requirements:

TFC-120-22-F-D and TFC-120-22-F-D-A share identical insulation height of 0.366" (9.30mm) and are directly interchangeable for applications with this specific board-to-board spacing requirement.

TFC-120-12-F-D-A features a reduced insulation height of 0.296" (7.52mm) and includes board guide features. This variant is suitable for applications requiring lower profile interconnection while maintaining all electrical specifications.

All parts support identical current (3.1A per contact) and voltage (275VAC) ratings across the full operating temperature range of -55°C to 125°C, ensuring thermal and electrical compatibility in equivalent system designs.

Frequently Asked Questions (FAQ)

Q: Can TFC-120-22-F-D-A replace TFC-120-22-F-D in existing designs?

A: Yes. Both parts share identical electrical ratings, pitch, row spacing, contact configuration, and insulation height. The addition of board guide features in the -A variant does not affect electrical compatibility.

Q: What is the primary difference between TFC-120-22-F-D-A and TFC-120-12-F-D-A?

A: The insulation height differs: TFC-120-22-F-D-A is 0.366" (9.30mm), while TFC-120-12-F-D-A is 0.296" (7.52mm). Both maintain identical electrical specifications and pitch. Selection depends on available board-to-board spacing in the application.

Q: Are all three parts suitable for the same current and voltage requirements?

A: Yes. All three parts are rated for 3.1A per contact and 275VAC, with operating temperature range of -55°C to 125°C.

Q: Do these parts require special handling or storage?

A: All parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant with UL94 V-0 flammability rating.

Q: What is the pitch specification for these connectors?

A: All parts feature 0.050" (1.27mm) mating pitch with 0.050" (1.27mm) row spacing, maintaining the Tiger Eye™ TFC series standard.
