Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TFM-120-32-S-D-A-P are identified based on compatibility within the Tiger Eye™ TFM series. The critical parameters that define substitutability are:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 40
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull

The identified substitutes maintain these core parameters. Variations occur in insulation height, which affects the overall profile of the connector but does not impact electrical performance or mating compatibility when the row spacing and pitch remain constant.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFM-120-32-S-D-A-P, TFM-120-32-S-D-A-K, and TFM-120-22-SM-D-A-P—are active products from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts should be based on:

1. Insulation height requirements: TFM-120-32-S-D-A-P and TFM-120-32-S-D-A-K both feature 0.435" (11.05mm) insulation height, while TFM-120-22-SM-D-A-P features 0.360" (9.14mm). Choose based on available PCB clearance and mechanical constraints.

2. Availability: All parts maintain active inventory status. TFM-120-32-S-D-A-P has the highest stock level at 947 units.

3. Electrical and thermal performance: All parts share identical electrical ratings (2.9A per contact, 275VAC) and operating temperature range (-55°C ~ 125°C), ensuring functional equivalence in power delivery and thermal applications.

Frequently Asked Questions (FAQ)

Q: Can TFM-120-32-S-D-A-K be used as a direct replacement for TFM-120-32-S-D-A-P?

A: Yes. Both parts share identical mating pitch (0.050"), row spacing (0.050"), number of positions (40), contact geometry, and electrical ratings. The insulation height is identical at 0.435" (11.05mm). These parts are mechanically and electrically interchangeable.

Q: What is the difference between TFM-120-22-SM-D-A-P and TFM-120-32-S-D-A-P?

A: The primary difference is insulation height. TFM-120-22-SM-D-A-P has an insulation height of 0.360" (9.14mm), while TFM-120-32-S-D-A-P has 0.435" (11.05mm). All other electrical and mechanical parameters, including mating pitch, row spacing, contact count, and electrical ratings, are identical. Selection depends on available PCB clearance.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts—TFM-120-32-S-D-A-P, TFM-120-32-S-D-A-K, and TFM-120-22-SM-D-A-P—are ROHS3 compliant and carry UL94 V-0 flammability ratings.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without special moisture control requirements.

Q: Can these connectors handle the same current and voltage?

A: Yes. All three parts are rated for 2.9A per contact and 275VAC, making them electrically equivalent for power delivery applications.
