Samtec TFC-110-02-F-D Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Samtec TFC-110-02-F-D is a surface mount rectangular connector header from the Tiger Eye™ TFC series. This 20-position, dual-row header operates at 0.050" (1.27mm) pitch and is designed for board-to-board or cable interconnection applications. The connector features shrouded 4-wall construction with push-pull fastening and gold-plated mating contacts rated for 3.1A per contact at 275VAC. The part is Active status and ROHS3 compliant, making it suitable for current production designs. Alternative part numbers within the same series provide equivalent electrical and mechanical performance with variations in assembly features and inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the TFC-110-02-F-D family is determined by electrical and mechanical parameter equivalence. All substitute parts maintain identical core specifications: 20-position, dual-row configuration at 0.050" (1.27mm) pitch, surface mount termination, shrouded 4-wall construction, push-pull fastening, and identical contact ratings (3.1A per contact, 275VAC). Operating temperature range, material composition, contact finish specifications, and compliance certifications (ROHS3, UL94 V-0, MSL 1) remain constant across all variants.

Substitution differences are limited to assembly-level features:

• TFC-110-02-F-D: Standard configuration
• TFC-110-02-F-D-A: Includes board guide feature
• TFC-110-02-F-D-K: Includes pick-and-place feature

These feature variations do not affect electrical performance or mating compatibility. Selection is based on assembly process requirements and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers (TFC-110-02-F-D, TFC-110-02-F-D-A, TFC-110-02-F-D-K) are Active status products from Samtec Inc. and maintain full ROHS3 compliance and UL94 V-0 flammability certification. Electrical and mechanical specifications are identical across all variants, ensuring direct substitution capability.

Selection between variants is determined by assembly process requirements:

TFC-110-02-F-D is the standard configuration suitable for manual or automated assembly without specific placement aids.

TFC-110-02-F-D-A includes a board guide feature, beneficial for applications requiring enhanced board alignment during mating operations.

TFC-110-02-F-D-K includes pick-and-place feature optimization, suitable for high-volume automated assembly environments.

Inventory availability should be considered as a secondary factor: TFC-110-02-F-D-A maintains the highest stock level (11,460 pcs), followed by TFC-110-02-F-D-K (1,088 pcs) and TFC-110-02-F-D (707 pcs).

Frequently Asked Questions (FAQ)

Q: Are TFC-110-02-F-D, TFC-110-02-F-D-A, and TFC-110-02-F-D-K electrically interchangeable?

A: Yes. All three part numbers share identical electrical specifications: 20 positions, 0.050" (1.27mm) pitch, 3.1A per contact rating, and 275VAC voltage rating. Mating contact geometry, finish specifications, and operating temperature range are identical.

Q: What is the difference between the three part numbers?

A: The differences are assembly-level features only. TFC-110-02-F-D-A includes a board guide for enhanced alignment. TFC-110-02-F-D-K includes pick-and-place optimization features. These variations do not affect electrical performance or mechanical mating compatibility.

Q: Can I substitute TFC-110-02-F-D-K for TFC-110-02-F-D in an existing design?

A: Yes. The parts are mechanically and electrically equivalent. The pick-and-place feature in the -K variant does not interfere with standard assembly processes or mating operations.

Q: Are all variants ROHS3 compliant?

A: Yes. TFC-110-02-F-D, TFC-110-02-F-D-A, and TFC-110-02-F-D-K are all ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: What is the operating temperature range for these connectors?

A: All variants operate across -55°C to 125°C, suitable for industrial and commercial applications.

Q: Which variant should I select for high-volume automated assembly?

A: TFC-110-02-F-D-K is optimized for pick-and-place automation. However, all variants are surface mount compatible and suitable for automated assembly; the -K variant simply includes additional placement optimization features.
