Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the TFM-120 series are qualified based on the following critical parameters that remain constant across all variants:

Fixed Parameters (Identical across all substitutes):

• 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: 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)
• Product Status: Active

Variable Parameter (Determines substitution eligibility):

• Insulation Height: Varies by part number designation

The TFM-120-12-S-D-A-P features an insulation height of 0.290" (7.37mm). Substitute parts TFM-120-22-SM-D-A-P and TFM-120-32-S-D-A-K maintain all electrical and mechanical specifications while offering alternative insulation heights of 0.360" (9.14mm) and 0.435" (11.05mm) respectively. These variants are interchangeable in applications where the increased insulation height does not create physical constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFM-120-12-S-D-A-P, TFM-120-22-SM-D-A-P, and TFM-120-32-S-D-A-K—are active products manufactured by Samtec Inc. within the Tiger Eye™ TFM series. Each part maintains ROHS3 compliance and UL94 V-0 material flammability rating, meeting current regulatory requirements.

Selection between these parts is determined by the physical space available on the printed circuit board. The primary difference is insulation height:

• TFM-120-12-S-D-A-P: 0.290" (7.37mm) insulation height—suitable for compact designs with minimal vertical clearance
• TFM-120-22-SM-D-A-P: 0.360" (9.14mm) insulation height—intermediate profile for standard board layouts
• TFM-120-32-S-D-A-K: 0.435" (11.05mm) insulation height—extended profile for applications requiring additional insulation clearance

All electrical parameters, including current rating (2.9A per Contact), voltage rating (275VAC), operating temperature range (-55°C ~ 125°C), and contact configuration remain identical. Substitution is valid when the target insulation height does not conflict with adjacent components or assembly constraints.

Frequently Asked Questions (FAQ)

Q: Can TFM-120-22-SM-D-A-P be used as a direct replacement for TFM-120-12-S-D-A-P?

A: Yes, provided the increased insulation height of 0.360" (9.14mm) versus 0.290" (7.37mm) does not create physical interference with surrounding components or assembly fixtures. All electrical specifications and contact configurations are identical.

Q: What is the primary difference between these three connector variants?

A: The insulation height is the only parameter that varies. TFM-120-12-S-D-A-P has 0.290" height, TFM-120-22-SM-D-A-P has 0.360" height, and TFM-120-32-S-D-A-K has 0.435" height. All other mechanical and electrical properties remain constant.

Q: Are all three parts RoHS compliant?

A: Yes, all three parts are ROHS3 compliant and carry UL94 V-0 material flammability rating.

Q: Do these connectors support the same current and voltage ratings?

A: Yes, all three variants support 2.9A per contact and 275VAC voltage rating with identical operating temperature range of -55°C ~ 125°C.

Q: What is the pitch specification for these connectors?

A: All three parts feature 0.050" (1.27mm) mating pitch with 0.050" (1.27mm) row spacing, maintaining the same contact density and board layout compatibility.

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

A: No, all three parts use phosphor bronze contacts with gold mating finish (30.0µin thickness) and tin post finish. Insulation material is liquid crystal polymer (LCP) for all variants.

Q: Which part should be selected for space-constrained applications?

A: TFM-120-12-S-D-A-P with 0.290" insulation height is the most compact option. Selection of TFM-120-22-SM-D-A-P or TFM-120-32-S-D-A-K depends on specific clearance requirements and board layout constraints.
