Frequently Asked Questions
How many positions does TFM-147-23-H-D carry and what is its contact pitch?
TFM-147-23-H-D provides 94 positions in a dual-row format on a 0.050-inch (1.27 mm) pitch. At half the spacing of a standard 2.54 mm pitch connector, the TFM series enables twice the contact density per unit board length, making it practical for high-signal-count mezzanine interfaces in compact FPGA and DSP processing modules.
What makes SAMTEC Tiger Eye terminal strips more reliable than standard socket strip designs?
SAMTEC's Tiger Eye contact geometry provides a controlled dual-beam wiping action that clears oxide and debris from the mating contact surface on every insertion cycle. This design sustains low contact resistance—typically under 20 mΩ—across thousands of mating cycles, which is essential for field-replaceable mezzanine boards in avionics, military computing, and industrial safety systems where connector failure is not acceptable.
Which mating socket strip is compatible with TFM-147-23-H-D for a complete 1.27 mm pitch board stack?
TFM-147-23-H-D mates with SAMTEC SFM or SFM-A series 0.050-inch pitch socket strips. Stacking heights in the SFM family range from approximately 4 mm to 20 mm, allowing designers to select the board separation that accommodates component height and thermal airflow requirements while maintaining full 94-position signal continuity across the mezzanine interface.
How does the 0.050-inch pitch of TFM-147-23-H-D affect PCB routing compared to standard 0.100-inch pitch headers?
The 0.050-inch (1.27 mm) pitch reduces the connector footprint by approximately 50% compared to a 2.54 mm pitch strip carrying the same 94 positions. This space saving is especially valuable in high-layer-count boards where routing 94 signals out of the connector requires multiple escape vias per row; the tighter pin grid reduces via escape distances and supports higher-speed differential pair routing at impedances near 50 Ω or 100 Ω differential.
