TFC-135-12-F-D-A Equivalent & Substitute Parts

Part Overview

The TFC-135-12-F-D-A is a Samtec Inc. rectangular connector header from the Tiger Eye™ TFC series, designed for surface mount board-to-board or cable applications. This 70-position connector features 0.050" (1.27mm) pitch mating with shrouded 4-wall construction and solder termination. The part is Active status and ROHS3 compliant, making it suitable for industrial and commercial electronic assemblies requiring reliable interconnection with push-pull fastening.

Alternative models may be required when application constraints demand different insulation heights, inventory availability, or specific stacking configurations within the same connector family.

Key Parameters

Substitute Part Grouping Explanation

The TFC-135-32-F-D-A qualifies as a direct substitute based on the following critical parameters that remain constant across both parts:

• Manufacturer: Samtec Inc.
• Series: Tiger Eye™ TFC
• Connector Type: Header with Male Pin contacts
• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 70
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Current Rating: 3.1A per Contact
• Voltage Rating: 275VAC
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The primary difference between these parts is the Insulation Height: TFC-135-12-F-D-A has 0.296" (7.52mm) while TFC-135-32-F-D-A has 0.441" (11.20mm). This dimensional variation allows selection based on specific PCB stack-up and mating clearance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both TFC-135-12-F-D-A and TFC-135-32-F-D-A are Active status products from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts depends solely on PCB design requirements related to insulation height clearance.

Use TFC-135-12-F-D-A (0.296" insulation height) for applications with space constraints or compact board stack-ups where lower profile connectors are required.

Use TFC-135-32-F-D-A (0.441" insulation height) for applications requiring increased clearance above the PCB surface or when mating with connectors designed for taller insulation profiles.

Both parts maintain identical electrical performance, contact ratings, operating temperature range, and compliance certifications. Substitution is mechanically feasible when insulation height requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Are TFC-135-12-F-D-A and TFC-135-32-F-D-A electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 3.1A per contact current rating, 275VAC voltage rating, gold-plated mating contacts, and phosphor bronze contact material. Electrical performance is equivalent.

Q: What is the primary difference between these two connector models?

A: The insulation height differs. TFC-135-12-F-D-A has 0.296" (7.52mm) insulation height, while TFC-135-32-F-D-A has 0.441" (11.20mm) insulation height. All other mechanical and electrical parameters remain identical.

Q: Can I substitute TFC-135-32-F-D-A for TFC-135-12-F-D-A in an existing design?

A: Substitution is possible only if the PCB layout and mating connector clearance accommodate the increased insulation height of 0.441" (11.20mm). Verify that the taller profile does not interfere with adjacent components or enclosure constraints.

Q: Can I substitute TFC-135-12-F-D-A for TFC-135-32-F-D-A in an existing design?

A: Substitution is possible only if the mating connector and PCB stack-up design can function with the reduced insulation height of 0.296" (7.52mm). Verify that the lower profile meets mechanical clearance requirements for your application.

Q: Do both parts have the same RoHS and flammability compliance?

A: Yes. Both TFC-135-12-F-D-A and TFC-135-32-F-D-A are ROHS3 compliant with UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the contact pitch for these connectors?

A: Both connectors feature 0.050" (1.27mm) pitch mating with 0.050" (1.27mm) row spacing across 70 positions arranged in 2 rows.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both parts operate across -55°C to 125°C temperature range, supporting industrial and commercial applications requiring extended thermal performance.
