Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFC-115-11-F-D is determined by strict equivalence in the following critical parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 30
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Current Rating: 3.1A per Contact
• Voltage Rating: 275VAC
• Operating Temperature Range: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The substitute part TFC-115-31-F-D-A meets all critical electrical and mechanical parameters. Variations in insulation height and board guide features do not affect core substitutability when mating interface and electrical performance remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both TFC-115-11-F-D and TFC-115-31-F-D-A are Active status products from Samtec Inc. with full ROHS3 compliance and identical electrical ratings. Selection between these parts depends on mechanical design requirements:

• TFC-115-11-F-D: Standard configuration with 0.290" (7.37mm) insulation height, suitable for applications with standard PCB spacing.
• TFC-115-31-F-D-A: Extended insulation height of 0.435" (11.05mm) with board guide feature, appropriate for applications requiring increased clearance or mechanical alignment assistance.

Both parts maintain identical mating pitch, contact ratings, voltage specifications, and temperature operating range. The choice between them is determined by available board space and mechanical mounting requirements, not electrical performance.

Frequently Asked Questions (FAQ)

Q: Can TFC-115-31-F-D-A be used as a direct replacement for TFC-115-11-F-D?

A: Yes, for applications where the increased insulation height of 0.435" (11.05mm) does not conflict with PCB layout constraints. The mating interface, electrical ratings, and contact specifications are identical. Board space availability must be verified before substitution.

Q: What is the significance of the board guide feature in TFC-115-31-F-D-A?

A: The board guide provides mechanical alignment assistance during mating. This feature does not affect electrical performance or contact integrity. Its utility depends on assembly process requirements and connector positioning needs.

Q: Are the contact ratings identical between these parts?

A: Yes. Both parts carry 3.1A per contact at 275VAC with identical contact materials (Phosphor Bronze), finishes (Gold mating, Tin post), and operating temperature range (-55°C ~ 125°C).

Q: What packaging is available for these parts?

A: Both TFC-115-11-F-D and TFC-115-31-F-D-A are supplied in tube packaging.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
