What are the key features of TFM-128-01-L-D-A-P-TR?
- 0.050" pitch dual-row 56-position low-profile board stacking connector reducing overall stack height in height-constrained enclosure designs
- Gold-plated mating contacts (A) over phosphor bronze providing stable contact resistance and reliable performance across extended operating life
- Tape-and-reel (TR) packaging with press-fit retention peg enabling automated SMT assembly at high throughput with minimal misalignment
What is TFM-128-01-L-D-A-P-TR used for?
The TFM-128-01-L-D-A-P-TR is designed for low-profile board-to-board stacking in portable devices, embedded computing modules, and communication equipment where minimizing stack height is critical. Its 56-pin dual-row layout at 0.050 inch pitch provides high signal density for complex I/O interfaces within tight height budgets. The tape-and-reel format with retention peg supports fully automated assembly in high-volume production of consumer electronics and industrial compact modules.

Frequently Asked Questions
How does the low-profile lead style of TFM-128-01-L-D-A-P-TR reduce assembly stack height compared to standard leads?
The L designation on the TFM-128-01-L-D-A-P-TR specifies low-profile leads that minimize the connector's vertical footprint, reducing total board stack height by several tenths of a millimeter compared to standard-profile 0.050 inch pitch connectors. This height reduction is critical in portable devices and compact embedded modules where the total PCB stack must remain under a tight enclosure height limit of 10 mm or less.
For a 56-pin bus interface design, what routing advantages does TFM-128-01-L-D-A-P-TR offer over a single-row alternative?
The dual-row configuration of the TFM-128-01-L-D-A-P-TR places 28 contacts per row at 0.050 inch pitch, achieving the same 56-pin count in roughly half the board length of a single-row connector. This halves the PCB edge length required for the connector, freeing valuable routing space along the board perimeter and reducing trace lengths for high-speed signals operating above 100 MHz.
What is the significance of the press-fit retention peg on TFM-128-01-L-D-A-P-TR during SMT reflow soldering?
The press-fit peg on the TFM-128-01-L-D-A-P-TR mechanically locks the 56-pin connector to the PCB before entering the reflow oven at temperatures up to 260°C, preventing thermal expansion from shifting the connector off its pads. This mechanical retention improves solder joint quality and reduces expensive rework in high-volume SMT lines, directly impacting production yield for complex multi-layer boards.
When is TFM-128-01-L-D-A-P-TR a practical alternative to higher-cost fine-pitch board stacking connectors for embedded modules?
TFM-128-01-L-D-A-P-TR is a cost-effective choice when an embedded module requires 56 signal or mixed-signal connections at 0.050 inch pitch without the premium pricing of 0.8 mm or finer pitch alternatives. Applications such as FPGA daughtercards, processor modules, and compact industrial I/O boards benefit from its gold-plated 56-pin contacts while achieving lower per-connector cost than proprietary fine-pitch stacking solutions rated above 500 MHz.
