TFM-110-22-S-D-A-P Equivalent & Substitute Parts

Part Overview

The TFM-110-22-S-D-A-P is a surface mount rectangular connector header manufactured by Samtec Inc. as part of the Tiger Eye™ TFM series. This connector is designed for board-to-board applications with 20 positions arranged in 2 rows at 0.050" (1.27mm) pitch. The part is currently active in production with 694 units in stock. Alternative models may be required due to inventory constraints, application-specific insulation height requirements, or design revisions necessitating compatible connector variants within the same series.

Substitute Part Grouping Explanation

The TFM-110-12-S-D-A-K qualifies as a direct substitute for the TFM-110-22-S-D-A-P based on the following critical parameters that determine functional compatibility:

• Manufacturer and Series: Both parts are manufactured by Samtec Inc. within the Tiger Eye™ TFM series
• Connector Type and Contact Configuration: Both are shrouded 4-wall headers with male pin contacts
• Position and Pitch: Both feature 20 positions in 2 rows at 0.050" (1.27mm) mating pitch and row spacing
• Electrical Ratings: Both support 2.9A per contact at 275VAC
• Mounting and Termination: Both are surface mount with solder termination and push-pull fastening
• Environmental and Compliance: Both operate across -55°C ~ 125°C, carry UL94 V-0 flammability rating, and are ROHS3 compliant

The primary difference between these parts is the insulation height: TFM-110-22-S-D-A-P has 0.360" (9.14mm) insulation height, while TFM-110-12-S-D-A-K has 0.290" (7.37mm) insulation height. This dimensional variation allows selection based on specific board layout and stacking requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the TFM-110-22-S-D-A-P and TFM-110-12-S-D-A-K are active production parts with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is determined by insulation height requirements:

• Select TFM-110-22-S-D-A-P when 0.360" (9.14mm) insulation height is specified in the design
• Select TFM-110-12-S-D-A-K when 0.290" (7.37mm) insulation height is required or when higher inventory availability is a consideration

Both parts maintain identical electrical performance, contact configuration, and environmental operating specifications. The choice is purely dimensional and application-specific.

Frequently Asked Questions (FAQ)

Q: Can TFM-110-12-S-D-A-K be used as a direct replacement for TFM-110-22-S-D-A-P?

A: Yes, provided the reduced insulation height of 0.290" (7.37mm) versus 0.360" (9.14mm) is compatible with the board layout and mating connector specifications. All electrical, mechanical, and environmental parameters are identical.

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

A: Insulation height determines the overall profile of the connector when mounted on the PCB. The TFM-110-12-S-D-A-K has a lower profile, which may be advantageous in space-constrained applications or when mating with connectors designed for lower stacking heights.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both TFM-110-22-S-D-A-P and TFM-110-12-S-D-A-K operate across -55°C ~ 125°C and carry identical UL94 V-0 flammability ratings.

Q: What are the electrical specifications for these connectors?

A: Both parts support 2.9A per contact at 275VAC. Contact material is phosphor bronze with gold mating finish (30.0µin thickness) and tin post finish.

Q: Are these parts RoHS compliant?

A: Yes. Both TFM-110-22-S-D-A-P and TFM-110-12-S-D-A-K are ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What is the pitch specification for these connectors?

A: Both parts feature 0.050" (1.27mm) mating pitch with 0.050" (1.27mm) row spacing in a 2-row, 20-position configuration.
