Substitute Part Grouping Explanation

Substitute parts for the TFM-150-12-SM-D-A are identified within the Tiger Eye™ TFM series based on the following criteria:

Invariant Parameters (Must Match):

• Manufacturer: Samtec Inc.
• Series: Tiger Eye™ TFM
• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 100
• 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
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Current Rating: 2.9A per Contact
• Voltage Rating: 275VAC
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameter (Differentiator):

• Insulation Height: Varies between substitute parts (0.290", 0.360", 0.435")

The TFM-150-12-SM-D-A, TFM-150-22-S-D-A, and TFM-150-32-S-D-A are functionally equivalent connectors with different insulation heights to accommodate various PCB stack-up requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFM-150-12-SM-D-A, TFM-150-22-S-D-A, and TFM-150-32-S-D-A—are Active status products from Samtec Inc. and maintain identical electrical specifications, contact ratings, and compliance certifications. Selection between these parts is determined solely by PCB design requirements and available stack-up height.

Selection Criteria:

• TFM-150-12-SM-D-A (0.290" insulation height): Use for compact designs with minimal vertical clearance.
• TFM-150-22-S-D-A (0.360" insulation height): Use for standard board-to-board spacing applications.
• TFM-150-32-S-D-A (0.435" insulation height): Use for applications requiring increased vertical separation or accommodating thicker PCB assemblies.

All parts are ROHS3 compliant, UL94 V-0 rated, and rated for -55°C to 125°C operation with 2.9A per contact and 275VAC voltage rating.

Frequently Asked Questions (FAQ)

Q: Can TFM-150-12-SM-D-A be directly replaced with TFM-150-22-S-D-A or TFM-150-32-S-D-A?

A: Direct replacement is possible only if the PCB design accommodates the increased insulation height. The TFM-150-22-S-D-A has 0.070" greater height, and the TFM-150-32-S-D-A has 0.145" greater height than the TFM-150-12-SM-D-A. Verify available vertical clearance before substitution.

Q: Are the electrical and thermal specifications identical across all three parts?

A: Yes. All three parts share identical current rating (2.9A per contact), voltage rating (275VAC), operating temperature range (-55°C to 125°C), contact finish (gold-plated), and compliance certifications (ROHS3, UL94 V-0).

Q: What determines which insulation height to select?

A: Insulation height is determined by the physical stack-up of your PCB assembly and the required clearance between the connector body and adjacent components or PCB layers. Measure available vertical space and select the appropriate height variant.

Q: Are all three parts in active production?

A: Yes. TFM-150-12-SM-D-A, TFM-150-22-S-D-A, and TFM-150-32-S-D-A are all Active status products from Samtec Inc.

Q: Do these parts require different soldering profiles or handling procedures?

A: No. All three parts are surface mount connectors with identical termination method (solder), contact material (phosphor bronze), and moisture sensitivity level (MSL 1 - Unlimited). Standard SMD assembly processes apply to all variants.
