TFM-105-32-S-D Equivalent & Substitute Parts

Part Overview

The TFM-105-32-S-D 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 or cable applications with 10 positions arranged in 2 rows at 0.050" (1.27mm) pitch. The part is currently active in production with full inventory availability. Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement in the same application context.

Substitute Part Grouping Explanation

The TFM-105-32-S-D has one identified substitute part: TFM-105-02-S-D-WT. Substitution eligibility is determined by the following critical parameters that must remain constant:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 10
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature: -55°C ~ 125°C
• Current Rating: 2.9A per Contact
• Voltage Rating: 275VAC
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part TFM-105-02-S-D-WT maintains all critical electrical and mechanical parameters. Variations exist only in contact length dimensions and insulation height, which do not affect functional compatibility in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TFM-105-32-S-D and TFM-105-02-S-D-WT are active production parts from Samtec Inc. within the Tiger Eye™ TFM series. Both parts maintain identical electrical specifications including current rating (2.9A per Contact), voltage rating (275VAC), operating temperature range (-55°C ~ 125°C), and material flammability rating (UL94 V-0). Both are ROHS3 compliant with MSL 1 (Unlimited) classification.

The primary differences between these parts are dimensional: the TFM-105-02-S-D-WT features a shorter contact length (0.131" vs 0.139") and reduced insulation height (0.220" vs 0.435"). The TFM-105-02-S-D-WT includes solder retention as an additional feature. Selection between these parts should be based on specific board-to-board spacing requirements and PCB layout constraints. Both parts are suitable for applications requiring push-pull fastening and surface mount assembly.

Frequently Asked Questions (FAQ)

Q: Can TFM-105-02-S-D-WT be used as a direct replacement for TFM-105-32-S-D?

A: Yes, both parts share identical electrical ratings, contact configuration, pitch spacing, and material specifications. The substitute part maintains all critical functional parameters. Selection depends on whether the dimensional differences (contact length and insulation height) are compatible with your specific board layout and mating component clearances.

Q: What are the key differences between these two connector headers?

A: The TFM-105-02-S-D-WT has a shorter contact length (0.131" versus 0.139") and lower insulation height (0.220" versus 0.435"). The substitute part also includes solder retention as a feature. All other electrical and mechanical specifications remain identical.

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

A: Yes, both the TFM-105-32-S-D and TFM-105-02-S-D-WT operate across the same temperature range of -55°C to 125°C.

Q: Do both parts meet the same compliance standards?

A: Yes, both parts are ROHS3 compliant, UL94 V-0 rated, and classified as MSL 1 (Unlimited). Both carry EAR99 ECCN classification and the same HTSUS code.

Q: What is the current and voltage rating for these connectors?

A: Both parts are rated for 2.9A per contact and 275VAC maximum voltage.

Q: Does the insulation height difference affect compatibility?

A: The insulation height difference may affect board-to-board spacing in applications with tight vertical clearance constraints. Verify that the lower profile of the TFM-105-02-S-D-WT (0.220" versus 0.435") is compatible with your specific application geometry before substitution.

Q: What is the pitch spacing for these connectors?

A: Both connectors feature a mating pitch of 0.050" (1.27mm) with row spacing also at 0.050" (1.27mm).
