TFC-110-11-F-D Equivalent & Substitute Parts

Part Overview

The TFC-110-11-F-D is a Samtec Tiger Eye™ TFC series rectangular connector header designed for through-hole board-to-board or cable applications. This shrouded 4-wall header features 20 positions arranged in 2 rows with 0.050" (1.27mm) pitch spacing. The connector is actively manufactured and maintains full RoHS3 compliance with UL94 V-0 flammability rating. Substitute parts are identified when electrical and mechanical parameters remain within the allowed specifications for this connector category, ensuring functional interchangeability in target applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFC-110-11-F-D is determined by strict equivalence across the following critical parameters:

• Connector type (Header), contact type (Male Pin), and series (Tiger Eye™ TFC)
• Electrical specifications: 20 positions, 2 rows, 0.050" (1.27mm) pitch and row spacing
• Mechanical mounting: Through hole, shrouded 4-wall configuration
• Electrical performance: 3.1A per contact, 275VAC rating, -55°C ~ 125°C operating range
• Compliance: RoHS3 compliant, UL94 V-0 flammability rating
• Contact materials and finishes: Phosphor bronze with gold mating finish and tin post finish

The TFC-110-31-F-D qualifies as a substitute based on identical values across all critical parameters. The only variance is insulation height (0.435" vs. 0.290"), which does not affect electrical or functional interchangeability in standard board-to-board applications where mating connector clearance is designed for the TFC series envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the TFC-110-11-F-D and TFC-110-31-F-D are active products manufactured by Samtec Inc. with full RoHS3 compliance and UL94 V-0 flammability certification. Selection between these parts depends on PCB layout requirements and available board space for the connector footprint.

The TFC-110-11-F-D features a lower insulation height of 0.290" (7.37mm), suitable for applications with space constraints or compact board designs. The TFC-110-31-F-D provides an increased insulation height of 0.435" (11.05mm), offering additional clearance above the PCB for component placement or cable routing in designs where vertical space is available.

Both connectors deliver identical electrical performance: 3.1A per contact, 275VAC rating, and -55°C ~ 125°C operating temperature range. Contact configuration, pitch spacing, shrouding design, and material specifications remain constant across both variants. Selection should be based solely on the mechanical envelope requirements of the target application and available PCB real estate.

Frequently Asked Questions (FAQ)

Q: Can TFC-110-31-F-D replace TFC-110-11-F-D in existing designs?

A: Yes, provided the increased insulation height of 0.435" (11.05mm) versus 0.290" (7.37mm) does not conflict with component placement or clearance requirements on the PCB. Electrical performance and contact configuration are identical.

Q: Are the mating connectors interchangeable between these two header variants?

A: Yes. Both headers feature identical pitch spacing (0.050"), row configuration (2 rows, 20 positions), and contact geometry. Standard Tiger Eye™ TFC series receptacles mate with both variants.

Q: What is the primary difference between TFC-110-11-F-D and TFC-110-31-F-D?

A: The sole difference is insulation height. The TFC-110-11-F-D has 0.290" (7.37mm) insulation height, while the TFC-110-31-F-D has 0.435" (11.05mm). All other specifications—electrical ratings, contact materials, pitch, row count, and compliance certifications—are identical.

Q: Do both parts meet the same compliance and certification standards?

A: Yes. Both the TFC-110-11-F-D and TFC-110-31-F-D are RoHS3 compliant, carry UL94 V-0 flammability rating, and maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: Which variant should I select for a new design?

A: Selection depends on available vertical space on your PCB. Use TFC-110-11-F-D for compact layouts requiring minimal height. Use TFC-110-31-F-D when additional clearance above the PCB is needed for component placement or cable management.
