Key Parameters

Substitute Part Grouping Explanation

The TFC-115-31-F-D-A qualifies as a direct substitute for the TFC-115-11-F-D-A based on the following critical parameters:

Matching Parameters (Substitution Basis):

• Manufacturer: Samtec Inc.
• Series: Tiger Eye™ TFC
• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 30
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Current Rating: 3.1A per Contact
• Voltage Rating: 275VAC
• Operating Temperature: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Differing Parameter:

• Insulation Height: TFC-115-11-F-D-A = 0.290" (7.37mm); TFC-115-31-F-D-A = 0.435" (11.05mm)

The insulation height difference reflects a design variation within the same product family. Both parts maintain identical electrical and mechanical interface specifications, allowing substitution based on application space constraints and PCB layout requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the TFC-115-11-F-D-A and TFC-115-31-F-D-A are active products manufactured by Samtec Inc. and maintain full ROHS3 compliance. Selection between these parts depends on PCB layout constraints and available vertical space:

• TFC-115-11-F-D-A is suitable for applications with limited vertical clearance, offering a compact 0.290" (7.37mm) insulation height.
• TFC-115-31-F-D-A accommodates designs requiring greater insulation height at 0.435" (11.05mm), with higher current inventory availability.

Both parts deliver identical electrical performance, contact ratings, and environmental specifications. The choice between them is determined by mechanical fit requirements within the target application.

Frequently Asked Questions (FAQ)

Q: Can TFC-115-31-F-D-A replace TFC-115-11-F-D-A in existing designs?

A: Yes, provided the increased insulation height of 0.435" (11.05mm) versus 0.290" (7.37mm) does not conflict with PCB layout or enclosure constraints. All electrical and contact specifications are identical.

Q: What is the significance of the insulation height difference?

A: Insulation height determines the vertical profile of the connector on the PCB. The TFC-115-31-F-D-A provides additional clearance above the board surface, which may be necessary for certain mechanical assemblies or beneficial for improved signal integrity in high-density layouts.

Q: Are both parts equally available?

A: The TFC-115-31-F-D-A has higher inventory availability at 1338 units compared to 923 units for the TFC-115-11-F-D-A. Both are active products with consistent supply.

Q: Do these parts require different mating connectors?

A: No. Both headers use identical 0.050" (1.27mm) pitch and row spacing, making them compatible with the same mating receptacles and cable assemblies.

Q: Are there compliance or certification differences?

A: Both parts are ROHS3 compliant, UL94 V-0 rated, and carry identical electrical certifications. No compliance differences exist between the two parts.
