TFC-105-12-F-D Equivalent & Substitute Parts

Part Overview

The TFC-105-12-F-D is a rectangular connector header manufactured by Samtec Inc. as part of the Tiger Eye™ TFC series. This surface mount connector features 10 positions arranged in 2 rows with 0.050" (1.27mm) pitch, designed for board-to-board or cable applications. The part is Active status and ROHS3 compliant. Substitute parts are identified when mechanical and electrical parameters remain within acceptable tolerances for the application, particularly insulation height variations that accommodate different PCB stackup requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TFC-105-12-F-D are identified within the Tiger Eye™ TFC series based on electrical and mechanical compatibility. The primary substitution criterion is insulation height variation, which accommodates different PCB stackup configurations while maintaining all other critical parameters:

Key Parameters Determining Substitution:

• Connector type, contact type, and position count (10 positions, 2 rows)
• Pitch specifications (0.050" mating pitch and row spacing)
• Electrical ratings (3.1A per contact, 275VAC)
• Contact material and finish (Phosphor Bronze with Gold mating finish)
• Mounting type and termination method (Surface Mount, Solder)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (ROHS3, UL94 V-0)

Variable Parameter:

• Insulation height: TFC-105-12-F-D (0.296"), TFC-105-22-F-D-A (0.366"), TFC-105-32-F-D-A (0.441")

The insulation height variation allows selection based on specific PCB assembly requirements without affecting electrical performance or contact integrity.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFC-105-12-F-D, TFC-105-22-F-D-A, and TFC-105-32-F-D-A—are Active status products manufactured by Samtec Inc. within the Tiger Eye™ TFC series. Each part maintains identical electrical specifications (3.1A per contact, 275VAC) and compliance certifications (ROHS3 Compliant, UL94 V-0). Selection between these parts is determined solely by PCB stackup requirements, as reflected in the insulation height specification:

• TFC-105-12-F-D: 0.296" (7.52mm) insulation height for compact assemblies
• TFC-105-22-F-D-A: 0.366" (9.30mm) insulation height with Board Guide feature for standard stackups
• TFC-105-32-F-D-A: 0.441" (11.20mm) insulation height with Board Guide feature for elevated stackups

All parts are suitable for direct substitution within the same application when insulation height compatibility is confirmed. No additional testing or verification is required beyond dimensional confirmation for the specific PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can TFC-105-22-F-D-A or TFC-105-32-F-D-A be used as direct replacements for TFC-105-12-F-D?

A: Yes, when PCB stackup dimensions permit. All three parts share identical electrical ratings, contact specifications, and compliance certifications. The only difference is insulation height. Confirm that the taller insulation height does not interfere with adjacent components or assembly constraints.

Q: What is the significance of the Board Guide feature in TFC-105-22-F-D-A and TFC-105-32-F-D-A?

A: The Board Guide feature is a mechanical design element included in these variants. It does not affect electrical performance or contact integrity. Selection should be based on PCB assembly requirements and available space.

Q: Are all three parts ROHS3 compliant?

A: Yes. TFC-105-12-F-D, TFC-105-22-F-D-A, and TFC-105-32-F-D-A are all ROHS3 compliant with UL94 V-0 flammability rating and Moisture Sensitivity Level 1 (Unlimited).

Q: What determines which insulation height variant to select?

A: Insulation height is determined by PCB stackup configuration and available vertical clearance. TFC-105-12-F-D (0.296") is suitable for compact designs, while TFC-105-22-F-D-A (0.366") and TFC-105-32-F-D-A (0.441") accommodate thicker PCB assemblies or elevated component placement.

Q: Do all variants support the same current and voltage ratings?

A: Yes. All three parts are rated for 3.1A per contact and 275VAC, with operating temperature range of -55°C to 125°C.

Q: What is the packaging format for these parts?

A: All three parts are supplied in Tube packaging format.
