TFM-110-02-F-D Equivalent & Substitute Parts

Part Overview

The TFM-110-02-F-D is a surface mount rectangular connector header manufactured by Samtec Inc. as part of the Tiger Eye™ TFM series. This 20-position, dual-row connector operates at 0.050" (1.27mm) pitch and is designed for board-to-board or cable applications with push-pull fastening. The part is Active status and widely stocked, with 710 units currently available. Substitute parts are identified when identical electrical and mechanical parameters are maintained across the connector interface, allowing for design flexibility and supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TFM-110-02-F-D is determined by strict equivalence across the following critical parameters:

• Connector type (Header), contact type (Male Pin), and fastening mechanism (Push-Pull)
• Position count (20) and row configuration (2 rows)
• Mating pitch (0.050" / 1.27mm) and row spacing (0.050" / 1.27mm)
• Mounting technology (Surface Mount) and shrouding design (Shrouded - 4 Wall)
• Electrical ratings: 2.9A per contact and 275VAC
• Operating temperature range (-55°C ~ 125°C)
• Material compliance (ROHS3, UL94 V-0)

The identified substitute TFM-110-02-F-D-A maintains all these parameters while introducing a Board Guide feature. This addition does not alter the core electrical or mechanical interface characteristics required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both TFM-110-02-F-D and TFM-110-02-F-D-A are Active status products with ROHS3 compliance and UL94 V-0 material flammability certification. The parts are electrically and mechanically equivalent across all interface parameters. The TFM-110-02-F-D-A includes a Board Guide feature and maintains higher inventory availability (1524 units versus 710 units). Selection between these parts should be based on design requirements for the Board Guide feature and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can TFM-110-02-F-D-A be used as a direct replacement for TFM-110-02-F-D?

A: Yes. Both parts maintain identical electrical ratings (2.9A per contact, 275VAC), mechanical pitch (0.050" / 1.27mm), position count (20), row configuration (2 rows), mounting type (Surface Mount), and operating temperature range (-55°C ~ 125°C). The Board Guide feature in the TFM-110-02-F-D-A does not alter the core connector interface.

Q: What is the significance of the Board Guide feature in TFM-110-02-F-D-A?

A: The Board Guide is a mechanical feature that aids in connector alignment during assembly. It does not change the electrical interface, mating pitch, or contact characteristics. Its presence or absence does not affect compatibility with mating connectors designed for the TFM series.

Q: Are there any differences in contact finish or material composition?

A: No. Both parts use identical contact materials (Phosphor Bronze), mating contact finish (Gold at 3.00µin thickness), and insulation material (Liquid Crystal Polymer). Contact shape, length, and all other physical specifications are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TFM-110-02-F-D and TFM-110-02-F-D-A are ROHS3 compliant with UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity level.

Q: Which part should be selected based on availability?

A: TFM-110-02-F-D-A has higher current inventory (1524 units) compared to TFM-110-02-F-D (710 units). If supply chain continuity is a consideration, TFM-110-02-F-D-A provides greater stock availability.
