Substitute Part Grouping Explanation

Substitute parts for the TFM-140-22-L-D-A are identified within the Tiger Eye™ TFM series based on identical electrical and mechanical specifications. The primary variable distinguishing these parts is insulation height, which accommodates different PCB stack-up configurations while preserving all other critical parameters.

Substitution is valid when the following parameters remain constant:

• Manufacturer: Samtec Inc.
• Series: Tiger Eye™ TFM
• Number of Positions: 80
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Push-Pull
• Contact Length - Mating: 0.139" (4.63mm)
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Current Rating: 2.9A per Contact
• Voltage Rating: 275VAC
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0

The variable parameter is insulation height, which differs across substitute parts to support various board-level integration requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFM-140-22-L-D-A, TFM-140-12-L-D-A, and TFM-140-32-L-D-A—maintain active product status and full compliance with ROHS3 and UL94 V-0 flammability requirements. Selection between these parts is determined solely by insulation height requirements for PCB stack-up accommodation.

TFM-140-12-L-D-A provides the lowest insulation height at 0.290" (7.37mm), suitable for compact board designs with minimal vertical clearance. TFM-140-22-L-D-A offers a mid-range insulation height of 0.360" (9.14mm) for standard applications. TFM-140-32-L-D-A provides the highest insulation height at 0.435" (11.05mm) for designs requiring additional vertical spacing.

All parts share identical electrical ratings, thermal operating range, contact materials, and fastening mechanisms, ensuring functional interchangeability within the specified insulation height constraints.

Frequently Asked Questions (FAQ)

Q: Can TFM-140-12-L-D-A be used as a direct replacement for TFM-140-22-L-D-A?

A: TFM-140-12-L-D-A is electrically and mechanically compatible with TFM-140-22-L-D-A. The only difference is insulation height: 0.290" (7.37mm) versus 0.360" (9.14mm). Substitution is valid only if the lower insulation height accommodates your PCB stack-up and clearance requirements.

Q: What determines compatibility between these substitute parts?

A: Compatibility is determined by matching electrical specifications (current rating, voltage rating, operating temperature), mechanical specifications (pitch, number of positions, row spacing, contact length), connector type (header, male pin), mounting method (surface mount), and shrouding configuration (shrouded 4-wall). Insulation height is the only variable parameter.

Q: Are all three parts ROHS3 compliant?

A: Yes. TFM-140-22-L-D-A, TFM-140-12-L-D-A, and TFM-140-32-L-D-A are all ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 (unlimited moisture sensitivity level).

Q: Which part should I select for a compact design with minimal vertical space?

A: TFM-140-12-L-D-A with insulation height of 0.290" (7.37mm) is the appropriate choice for compact designs. Verify that this height accommodates your mating connector and PCB layout requirements.

Q: What is the difference between the three insulation heights?

A: TFM-140-12-L-D-A: 0.290" (7.37mm); TFM-140-22-L-D-A: 0.360" (9.14mm); TFM-140-32-L-D-A: 0.435" (11.05mm). Selection depends on available vertical clearance on your PCB assembly.

Q: Do these parts have different current or voltage ratings?

A: No. All three parts maintain identical current rating of 2.9A per contact and voltage rating of 275VAC.

Q: Are there any packaging or inventory differences?

A: All parts are packaged in tubes. Current inventory levels differ: TFM-140-22-L-D-A (935 units), TFM-140-12-L-D-A (974 units), TFM-140-32-L-D-A (1383 units).
