Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-120-01-F-D is determined by strict equivalence across the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 40
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Current Rating: 2.9A per Contact
• Voltage Rating: 275VAC
• Operating Temperature: -55°C ~ 125°C
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The substitute part TFM-120-01-F-D-A meets all critical electrical and mechanical parameters. The only documented difference is the addition of a Board Guide feature in the substitute variant, which does not alter the core functional or electrical characteristics required for interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both TFM-120-01-F-D and TFM-120-01-F-D-A are active products manufactured by Samtec Inc. and maintain full compliance with ROHS3 standards. Both connectors satisfy identical electrical specifications including current rating, voltage rating, and operating temperature range.

The TFM-120-01-F-D-A includes a Board Guide feature that provides enhanced mechanical alignment during assembly. This feature does not compromise electrical performance or mechanical compatibility with mating connectors designed for the standard TFM-120-01-F-D.

Selection between these parts should be based on:

• PCB layout requirements and the benefit of board guide alignment
• Current inventory availability and supply chain lead times
• Design revision control and documentation requirements

Both parts are suitable for direct substitution in applications requiring 40-position, 1.27mm pitch rectangular connectors with the specified electrical and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can TFM-120-01-F-D-A be used as a direct replacement for TFM-120-01-F-D?

A: Yes. The TFM-120-01-F-D-A meets all critical electrical and mechanical parameters of the TFM-120-01-F-D. The addition of a Board Guide feature in the substitute variant does not alter core functionality or electrical performance.

Q: What is the difference between TFM-120-01-F-D and TFM-120-01-F-D-A?

A: The primary difference is the Board Guide feature present in the TFM-120-01-F-D-A. This feature provides mechanical alignment assistance during assembly but does not affect electrical specifications, contact ratings, or mating compatibility.

Q: Are both parts compatible with the same mating connectors?

A: Yes. Both parts share identical pitch, row spacing, contact type, and shrouding specifications. They are compatible with the same mating connector designs.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by equivalence in connector type, contact type, number of positions, rows, pitch, row spacing, mounting type, termination method, shrouding, current rating, voltage rating, operating temperature range, contact finish, contact material, insulation material, and flammability rating.

Q: Are both parts RoHS compliant?

A: Yes. Both TFM-120-01-F-D and TFM-120-01-F-D-A are ROHS3 compliant.

Q: What is the current inventory status for each part?

A: TFM-120-01-F-D has 1083 units in stock. TFM-120-01-F-D-A has 709 units in stock.
