Samtec TFM-110-32-S-D-A-P Equivalent & Substitute Parts

Part Overview

The Samtec TFM-110-32-S-D-A-P is a surface mount rectangular connector header from the Tiger Eye™ TFM series, featuring 20 positions at 1.27mm pitch with shrouded 4-wall design. This connector is classified as Active product status and is suitable for board-to-board or cable applications requiring push-pull fastening. Substitute parts may be required due to design revisions, manufacturing availability, or specific application requirements such as mounting type changes or insulation height modifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-110-32-S-D-A-P is determined by the following critical parameters: connector type (Header), contact type (Male Pin), pitch (1.27mm), number of positions (20), number of rows (2), shrouding configuration (Shrouded - 4 Wall), fastening type (Push-Pull), contact material (Phosphor Bronze), insulation material (Liquid Crystal Polymer), current rating (2.9A per Contact), voltage rating (275VAC), operating temperature range (-55°C ~ 125°C), and compliance certifications (ROHS3, UL94 V-0).

The TFM-110-12-S-D-A-K qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while differing only in insulation height (0.290" vs 0.435"). The TFM-105-01-S-D-WT is a partial substitute suitable for applications where position count reduction (10 vs 20) and through-hole mounting are acceptable design modifications.

Parameter Comparison

Engineering Selection Recommendations

The TFM-110-12-S-D-A-K is the primary substitute for the TFM-110-32-S-D-A-P. Both parts maintain identical electrical specifications, contact configurations, and compliance certifications. The difference in insulation height (0.290" versus 0.435") is a mechanical variation that does not affect electrical performance or thermal characteristics. Both parts are Active status products with ROHS3 compliance and UL94 V-0 flammability rating.

The TFM-105-01-S-D-WT serves as an alternative for applications where position count reduction from 20 to 10 is acceptable and through-hole mounting is preferred over surface mount. This part maintains equivalent electrical ratings and compliance certifications but requires PCB layout modifications due to the different mounting technology and reduced position count.

Frequently Asked Questions (FAQ)

Q: Can TFM-110-12-S-D-A-K replace TFM-110-32-S-D-A-P in all applications?

A: Yes, for applications where the insulation height difference (0.290" versus 0.435") does not create mechanical interference. Both parts share identical electrical specifications, pitch, position count, contact materials, and compliance ratings.

Q: What is the primary difference between TFM-110-12-S-D-A-K and TFM-110-32-S-D-A-P?

A: The insulation height differs: TFM-110-12-S-D-A-K measures 0.290" (7.37mm) while TFM-110-32-S-D-A-P measures 0.435" (11.05mm). All other electrical and mechanical parameters are identical.

Q: When should TFM-105-01-S-D-WT be considered?

A: TFM-105-01-S-D-WT is suitable when design requirements permit through-hole mounting instead of surface mount and when 10 positions satisfy the application instead of 20. This part maintains equivalent electrical performance and compliance standards.

Q: Are all three parts ROHS3 compliant?

A: Yes. TFM-110-32-S-D-A-P, TFM-110-12-S-D-A-K, and TFM-105-01-S-D-WT are all ROHS3 compliant with UL94 V-0 flammability rating.

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

A: All three parts are rated for 2.9A per contact and 275VAC, with operating temperature range of -55°C to 125°C.

Q: Does mounting type affect electrical performance?

A: No. Surface mount (TFM-110-32-S-D-A-P, TFM-110-12-S-D-A-K) and through-hole (TFM-105-01-S-D-WT) mounting types do not affect electrical specifications. Selection depends on PCB design requirements.
