Key Parameters

Substitute Part Grouping Explanation

The TFM-150-22-L-D-A qualifies as a direct substitute based on the following critical parameters that remain identical:

• Manufacturer and Series: Samtec Inc., Tiger Eye™ TFM
• Connector Type and Contact Type: Header with Male Pin contacts
• Number of Positions and Rows: 100 positions in 2-row configuration
• Pitch and Row Spacing: 0.050" (1.27mm) mating pitch and row spacing
• Mounting and Termination: Surface Mount with Solder termination
• Fastening Type: Push-Pull
• Electrical Ratings: 2.9A per Contact, 275VAC
• Operating Temperature: -55°C ~ 125°C
• Compliance: ROHS3 Compliant, UL94 V-0 flammability rating
• Contact Material and Finish: Phosphor Bronze with Gold mating finish (15.0µin)

The primary difference between these parts is the Insulation Height: TFM-150-12-L-D-A has 0.290" (7.37mm) while TFM-150-22-L-D-A has 0.360" (9.14mm). This variation accommodates different PCB stack-up requirements while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both TFM-150-12-L-D-A and TFM-150-22-L-D-A are Active products with identical compliance certifications (ROHS3 Compliant, UL94 V-0). Selection between these parts depends on PCB stack-up geometry and available clearance height. The TFM-150-12-L-D-A with 0.290" (7.37mm) insulation height is suitable for compact designs with limited vertical space. The TFM-150-22-L-D-A with 0.360" (9.14mm) insulation height accommodates applications requiring greater clearance above the PCB surface. Both parts maintain identical electrical performance, contact ratings, and environmental specifications. Inventory availability should be evaluated based on procurement timeline and volume requirements.

Frequently Asked Questions (FAQ)

Q: Can TFM-150-22-L-D-A be used as a direct replacement for TFM-150-12-L-D-A?

A: Yes, provided the PCB stack-up and available clearance height accommodate the increased insulation height of 0.360" (9.14mm) versus 0.290" (7.37mm). All electrical, mechanical, and compliance parameters are identical.

Q: What is the primary difference between these two connector models?

A: The insulation height differs. TFM-150-12-L-D-A has 0.290" (7.37mm) insulation height, while TFM-150-22-L-D-A has 0.360" (9.14mm). This accommodates different PCB design requirements without affecting electrical performance.

Q: Are the contact pitch and row spacing identical?

A: Yes. Both parts feature 0.050" (1.27mm) mating pitch and 0.050" (1.27mm) row spacing, ensuring identical footprint and mating interface compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TFM-150-12-L-D-A and TFM-150-22-L-D-A are ROHS3 Compliant with UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the current and voltage rating for these connectors?

A: Both parts are rated for 2.9A per contact and 275VAC, with operating temperature range of -55°C to 125°C.

Q: Are the contact materials and finishes the same?

A: Yes. Both parts use Phosphor Bronze contacts with Gold mating finish (15.0µin / 0.38µm thickness) and Tin post finish.
