TFM-120-12-L-D-A-P-TR Equivalent & Substitute Parts

Part Overview

The TFM-120-12-L-D-A-P-TR is a surface mount rectangular connector header from Samtec Inc.'s Tiger Eye™ TFM series. This 40-position, dual-row connector operates at 0.050" (1.27mm) pitch and is designed for board-to-board or cable applications with push-pull fastening. The part is active in production with full inventory availability. Substitute parts are identified when design requirements permit variations in insulation height while maintaining all critical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TFM-120-12-L-D-A-P-TR are identified based on equivalence in the following critical parameters:

• Connector type, contact type, and fastening mechanism (Header, Male Pin, Push-Pull)
• Electrical specifications: pitch (0.050"), position count (40), row configuration (2 rows), current rating (2.9A per contact), and voltage rating (275VAC)
• Mechanical compatibility: surface mount termination, solder attachment, shrouded 4-wall design
• Material and environmental compliance: phosphor bronze contacts with gold mating finish, LCP insulation, UL94 V-0 flammability rating, ROHS3 compliance, MSL 1

The identified substitutes differ only in insulation height, which is a non-critical parameter for board-to-board connectivity when mating surface clearance permits the variation. All other electrical, mechanical, and compliance characteristics remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between TFM-120-12-L-D-A-P-TR and its substitutes (TFM-120-32-L-D-A-K-TR and TFM-120-32-L-D-A-P-TR) depends on available board clearance and mating surface geometry. The primary difference is insulation height: the main part measures 0.290" (7.37mm) while both substitutes measure 0.435" (11.05mm). This variation does not affect electrical performance, contact integrity, or compliance certifications. Inventory availability is higher for substitute parts, with 1068 and 1699 units in stock compared to 642 units for the main part.

Frequently Asked Questions (FAQ)

Q: Can TFM-120-32-L-D-A-K-TR and TFM-120-32-L-D-A-P-TR be used interchangeably with TFM-120-12-L-D-A-P-TR?

A: Yes, provided the PCB layout accommodates the increased insulation height of 0.435" (11.05mm) versus 0.290" (7.37mm). All electrical parameters, contact configurations, and compliance ratings are identical.

Q: What is the difference between TFM-120-32-L-D-A-K-TR and TFM-120-32-L-D-A-P-TR?

A: Both parts are identical in all provided specifications. The difference in part number designation reflects internal Samtec coding but does not indicate functional or electrical variation.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. All three parts share identical current ratings (2.9A per contact), voltage ratings (275VAC), operating temperature ranges (-55°C ~ 125°C), and contact materials.

Q: What should be considered when selecting between these parts?

A: Primary considerations are PCB clearance for the insulation height variation and inventory availability. All parts are ROHS3 compliant with MSL 1 rating and identical solder termination requirements.

Q: Are these parts suitable for high-frequency applications?

A: The provided specifications do not include frequency-dependent parameters. Consult detailed datasheets for impedance and high-frequency performance characteristics.
