Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the Tiger Eye™ TFC series are qualified based on the following core parameters that determine functional interchangeability:

• Connector Type & Contact Configuration: All substitutes maintain Header type with Male Pin contacts
• Electrical Specifications: Identical pitch (0.050"), position count (80), row configuration (2 rows), current rating (3.1A per contact), and voltage rating (275VAC)
• Mechanical Interface: All parts feature Surface Mount termination, Push-Pull fastening, and Shrouded 4-Wall construction
• Material & Environmental Compliance: Phosphor Bronze contacts with Gold mating finish, LCP insulation, UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 rating
• Operating Conditions: Identical temperature range (-55°C ~ 125°C)

The primary variable among substitutes is Insulation Height, which affects board-level stacking and clearance requirements. This parameter does not impact electrical performance but must be evaluated for mechanical fit within the application.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFC-140-22-F-D-A, TFC-140-12-F-D-A, and TFC-140-32-F-D-A—are Active status products from Samtec Inc. and maintain full ROHS3 compliance and UL94 V-0 flammability certification. Electrical performance is identical across all variants, with matching current and voltage ratings suitable for industrial applications.

Selection between these parts is determined by mechanical clearance requirements on the PCB. The TFC-140-12-F-D-A offers the lowest profile at 0.296" (7.52mm) insulation height, suitable for space-constrained designs. The TFC-140-22-F-D-A provides a mid-range profile at 0.366" (9.30mm). The TFC-140-32-F-D-A delivers the highest profile at 0.441" (11.20mm) for applications requiring additional clearance above the PCB surface.

All parts feature identical contact geometry, mating pitch, and fastening mechanisms, ensuring functional interchangeability when mechanical envelope constraints are satisfied.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable?

A: Yes. All three parts maintain identical electrical specifications including 80-position configuration, 0.050" (1.27mm) pitch, 3.1A per contact current rating, and 275VAC voltage rating. Electrical performance is not affected by insulation height variation.

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

A: The insulation height differs across the three variants. TFC-140-12-F-D-A measures 0.296" (7.52mm), TFC-140-22-F-D-A measures 0.366" (9.30mm), and TFC-140-32-F-D-A measures 0.441" (11.20mm). This affects board-level clearance and stacking height but does not impact electrical function.

Q: Can I substitute TFC-140-12-F-D-A for TFC-140-22-F-D-A in an existing design?

A: Substitution is possible if the PCB layout accommodates the lower profile of 0.296" (7.52mm). Verify that no components or clearance constraints conflict with the reduced insulation height. Mating connector compatibility remains unchanged.

Q: Can I substitute TFC-140-32-F-D-A for TFC-140-22-F-D-A?

A: Substitution is possible if the PCB layout accommodates the higher profile of 0.441" (11.20mm). Verify that no height restrictions or component interference occurs with the increased insulation height. Electrical and mechanical interface compatibility is maintained.

Q: Are all parts ROHS3 compliant?

A: Yes. All three parts carry ROHS3 compliance certification and are suitable for applications requiring regulatory compliance with hazardous substance restrictions.

Q: What is the moisture sensitivity level for these connectors?

A: All parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Do these parts require different mating connectors?

A: No. All three parts share identical pitch (0.050"), position count (80), row configuration (2 rows), and contact geometry. They mate with the same connector family and are mechanically compatible with standard Tiger Eye™ TFC series receptacles.
