What are the key features of TFM-120-21-L-D?
- 40-position dual-row SMD receptacle at 0.050" (1.27 mm) pitch enables high-density board-to-board connections
- Gold-over-nickel mating contacts provide low contact resistance and long mating cycle durability
- Low-profile (-L) body height minimizes vertical stack clearance for compact stacked-board assemblies
What is TFM-120-21-L-D used for?
The TFM-120-21-L-D is well-suited for mezzanine and module-to-carrier board interconnections in compact embedded systems, where its 0.050" pitch dual-row layout allows high signal density in limited PCB space. Its gold-over-nickel contact finish ensures reliable electrical performance across thousands of mating cycles in computing modules, FPGA development boards, and data acquisition systems. RoHS compliance makes it appropriate for designs targeting global market regulations.

Frequently Asked Questions
What contact finish does the TFM-120-21-L-D use and why does it matter for reliability?
The TFM-120-21-L-D uses gold-over-nickel mating contacts, which provide low contact resistance, excellent corrosion resistance, and support for high mating cycle counts exceeding 100 insertions without significant degradation.
For a compact stacked-PCB design, how does the TFM-120-21-L-D's low-profile body help?
The -L designation indicates a low-profile body that reduces the board-to-board stack height to approximately 4 mm, compared to standard-height variants. This makes the TFM-120-21-L-D suitable for slim enclosures and tightly spaced PCB assemblies with 40 dual-row pins at 1.27 mm pitch.
Is the TFM-120-21-L-D compatible with RoHS environmental regulations?
Yes, the TFM-120-21-L-D is fully RoHS compliant with tin-nickel termination contacts and a halogen-free body, enabling deployment in products targeting EU environmental regulations and other global markets requiring lead-free construction.
