Key Parameters

Substitute Part Grouping Explanation

The TFC-135-32-F-D-A qualifies as a direct substitute for the TFC-135-22-F-D based on the following critical parameters:

Matching Parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (70 positions, 2 rows)
• Mating pitch and row spacing (0.050" / 1.27mm)
• Mounting method and shrouding (Surface Mount, Shrouded - 4 Wall)
• Fastening mechanism (Push-Pull)
• Electrical ratings (3.1A per contact, 275VAC)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish and material specifications (Gold mating finish, Phosphor Bronze)
• Insulation material and flammability (LCP, UL94 V-0)
• Compliance certifications (ROHS3, MSL 1)

Distinguishing Parameter:

• Insulation Height: TFC-135-22-F-D = 0.366" (9.30mm); TFC-135-32-F-D-A = 0.441" (11.20mm)
• Additional Feature: TFC-135-32-F-D-A includes Board Guide

The increased insulation height and board guide feature in the substitute part provide enhanced mechanical stability and alignment during mating operations without compromising electrical performance or thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the TFC-135-22-F-D and TFC-135-32-F-D-A are Active status products from Samtec's Tiger Eye™ TFC series, ensuring ongoing manufacturer support and availability. Both parts maintain identical electrical performance specifications, thermal operating ranges, and compliance certifications including ROHS3 and UL94 V-0 flammability ratings.

The primary selection criterion is mechanical fit within the PCB assembly. The TFC-135-32-F-D-A features a 0.075" (1.90mm) greater insulation height and integrated board guide, providing enhanced mechanical alignment and stability. Select the TFC-135-32-F-D-A when PCB layout accommodates the increased height and when additional mechanical guidance is beneficial. Select the TFC-135-22-F-D when space constraints require the lower profile configuration.

Both parts are suitable for direct substitution in applications where the mechanical envelope permits the dimensional variation.

Frequently Asked Questions (FAQ)

Q: Can TFC-135-32-F-D-A replace TFC-135-22-F-D in existing designs?

A: Yes, provided the PCB assembly accommodates the 0.075" (1.90mm) increase in insulation height. All electrical parameters, mating pitch, contact ratings, and operating specifications are identical. The board guide feature in the substitute part provides additional mechanical stability without affecting electrical performance.

Q: What is the significance of the board guide feature in TFC-135-32-F-D-A?

A: The board guide provides mechanical alignment assistance during connector mating operations, reducing insertion force variability and improving repeatability in high-volume assembly environments. This feature does not alter electrical characteristics or thermal performance.

Q: Are both parts suitable for the same temperature and voltage applications?

A: Yes. Both parts operate across -55°C to 125°C and are rated for 275VAC with 3.1A per contact. Thermal and electrical performance are equivalent.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both TFC-135-22-F-D and TFC-135-32-F-D-A are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity levels. Compliance certifications are identical.

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

A: The insulation height differs by 0.075" (1.90mm), with TFC-135-32-F-D-A being taller. The substitute part also includes a board guide feature. All other mechanical and electrical specifications are identical.

Q: Can I use TFC-135-22-F-D as a substitute for TFC-135-32-F-D-A?

A: Substitution in the reverse direction is possible only if the PCB assembly design does not require the board guide feature and can accommodate the reduced insulation height. Electrical compatibility is maintained in both directions.
