Substitute Part Grouping Explanation

Substitute parts TFC-115-22-F-D-A and TFC-115-32-F-D-A are direct equivalents within the Tiger Eye™ TFC series. Substitution is determined by the following invariant parameters:

• Manufacturer: Samtec Inc.
• Series: Tiger Eye™ TFC
• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 30
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• 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 variable parameter is Insulation Height, which differs across the three parts to accommodate various PCB stack-up requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFC-115-12-F-D-A, TFC-115-22-F-D-A, and TFC-115-32-F-D-A—are active products manufactured by Samtec Inc. and carry ROHS3 compliance with UL94 V-0 flammability rating. Selection between these parts is determined solely by PCB stack-up height requirements:

• TFC-115-12-F-D-A: 0.296" (7.52mm) insulation height for compact assemblies
• TFC-115-22-F-D-A: 0.366" (9.30mm) insulation height for standard stack-up configurations
• TFC-115-32-F-D-A: 0.441" (11.20mm) insulation height for elevated stack-up requirements

All electrical parameters, mechanical interfaces, contact ratings, and environmental specifications remain identical across the three variants. Substitution is electrically and mechanically transparent when the appropriate insulation height is selected for the target application.

Frequently Asked Questions (FAQ)

Q: Can TFC-115-22-F-D-A be used as a direct replacement for TFC-115-12-F-D-A?

A: Electrical and mechanical compatibility is maintained. The primary difference is insulation height: TFC-115-22-F-D-A is 0.070" (1.78mm) taller. Substitution is valid only if the PCB stack-up and mating connector clearance accommodate the increased height.

Q: What determines compatibility between these three parts?

A: All three parts share identical electrical ratings (3.1A per contact, 275VAC), contact pitch (0.050"), number of positions (30), mounting type (surface mount), and environmental specifications (-55°C to 125°C). The only variable is insulation height, which must match the mechanical requirements of the application.

Q: Are all three parts ROHS3 compliant?

A: Yes. TFC-115-12-F-D-A, TFC-115-22-F-D-A, and TFC-115-32-F-D-A are all ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 (unlimited moisture sensitivity level).

Q: Which part should be selected for a new design?

A: Selection is based on PCB stack-up geometry. Measure the available vertical space between the PCB surface and the mating connector interface. Select the part whose insulation height fits within this constraint while providing adequate clearance.

Q: Are there any differences in contact finish or material between these parts?

A: No. All three parts use phosphor bronze contacts with gold mating finish (3.00µin thickness) and tin post finish. Contact material, finish specifications, and electrical properties are identical.
