TFM-140-32-S-D-A-P Equivalent & Substitute Parts

Part Overview

The TFM-140-32-S-D-A-P is a surface mount rectangular connector header manufactured by Samtec Inc. as part of the Tiger Eye™ TFM series. This 80-position, dual-row connector operates at 0.050" (1.27mm) pitch and is designed for board-to-board or cable applications with push-pull fastening. The part is currently active in production with full inventory availability. Alternative models within the TFM series may be required when specific insulation height or mechanical envelope constraints differ from the primary specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the TFM-140 series is determined by the following critical parameters that must remain constant:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 80
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Current Rating: 2.9A per Contact
• Voltage Rating: 275VAC
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The TFM-140-12-S-D-A-K qualifies as a substitute based on identical electrical and mechanical specifications. The primary difference is the insulation height, which varies from 0.435" (11.05mm) to 0.290" (7.37mm). This dimensional variation allows selection based on specific PCB stack-up or mechanical envelope requirements while maintaining full electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TFM-140-32-S-D-A-P and TFM-140-12-S-D-A-K are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is determined by mechanical envelope constraints:

• Select TFM-140-32-S-D-A-P when the application requires an insulation height of 0.435" (11.05mm)
• Select TFM-140-12-S-D-A-K when the application requires an insulation height of 0.290" (7.37mm)

Both parts maintain identical electrical performance, contact ratings, operating temperature range, and compliance certifications. Interchangeability is limited to applications where the specific insulation height does not affect PCB layout, mating connector clearance, or mechanical assembly.

Frequently Asked Questions (FAQ)

Q: Are TFM-140-32-S-D-A-P and TFM-140-12-S-D-A-K electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 2.9A per contact current rating, 275VAC voltage rating, and -55°C to 125°C operating temperature range. Interchangeability is limited to mechanical envelope compatibility.

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

A: The insulation height differs. TFM-140-32-S-D-A-P has an insulation height of 0.435" (11.05mm), while TFM-140-12-S-D-A-K has an insulation height of 0.290" (7.37mm). All other mechanical and electrical parameters remain identical.

Q: Do both parts use the same contact pitch and row spacing?

A: Yes. Both connectors use 0.050" (1.27mm) pitch for mating and 0.050" (1.27mm) row spacing. Both accommodate 80 positions in a 2-row configuration.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, UL94 V-0 rated, and carry Moisture Sensitivity Level 1 (Unlimited). Both are active production parts from Samtec Inc.

Q: Which part should I select for a space-constrained application?

A: Select TFM-140-12-S-D-A-K for applications with limited vertical clearance, as its 0.290" (7.37mm) insulation height is lower than the TFM-140-32-S-D-A-P at 0.435" (11.05mm).
