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

Part Overview

The Samtec TFM-110-32-S-D-A is a surface mount rectangular connector header from the Tiger Eye™ TFM series. This shrouded 4-wall header connector features 20 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 widely used in applications requiring reliable push-pull mated connections with gold-plated contacts. Alternative models within the same series become necessary when specific insulation height requirements differ due to PCB layout constraints or mechanical clearance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the Samtec TFM-110 series is determined by the following critical parameters that must remain constant:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 20
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Current Rating: 2.9A per Contact
• Voltage Rating: 275VAC
• Operating Temperature: -55°C ~ 125°C

The primary variable distinguishing substitute parts is Insulation Height, which affects mechanical clearance and board-level integration. The TFM-110-32-S-D-A features an insulation height of 0.435" (11.05mm), while substitute models TFM-110-12-S-D-A and TFM-110-22-S-D-A provide alternative heights of 0.290" (7.37mm) and 0.360" (9.14mm) respectively. All three parts share identical electrical specifications, contact materials, and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFM-110-32-S-D-A, TFM-110-12-S-D-A, and TFM-110-22-S-D-A—maintain Active product status and full compliance with ROHS3, REACH Unaffected, and UL94 V-0 flammability standards. Selection between these parts is determined solely by mechanical clearance requirements on the PCB. The TFM-110-32-S-D-A with 0.435" (11.05mm) insulation height is suitable for applications requiring maximum standoff distance. The TFM-110-12-S-D-A with 0.290" (7.37mm) insulation height accommodates space-constrained designs. The TFM-110-22-S-D-A with 0.360" (9.14mm) insulation height provides an intermediate option. All parts deliver identical electrical performance, contact reliability, and environmental operating ranges.

Frequently Asked Questions (FAQ)

Q: Can TFM-110-12-S-D-A be used as a direct replacement for TFM-110-32-S-D-A?

A: Electrical and functional compatibility is complete. However, the insulation height differs: TFM-110-12-S-D-A measures 0.290" (7.37mm) versus 0.435" (11.05mm) for TFM-110-32-S-D-A. Substitution is valid only if PCB layout and mechanical clearance accommodate the reduced height.

Q: What determines compatibility between these three connector models?

A: Compatibility is based on matching pitch (0.050"), position count (20), row configuration (2 rows), contact type (male pin), shrouding (4-wall), fastening mechanism (push-pull), and electrical ratings (2.9A per contact, 275VAC). Insulation height is the only variable parameter.

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

A: Yes. All three parts operate across -55°C to 125°C and maintain identical contact material (phosphor bronze), contact finish (gold-plated), and flammability rating (UL94 V-0).

Q: What is the inventory status for these substitute parts?

A: TFM-110-32-S-D-A: 1066 pcs; TFM-110-12-S-D-A: 2060 pcs; TFM-110-22-S-D-A: 1021 pcs. All are new original stock in tube packaging.

Q: Do these connectors require any special handling or storage considerations?

A: All three parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control measures.
