What are the key features of TFM-146-02-H-D-LC?
- 92-position dual-row Tiger Eye terminal strip at 0.050 inch (1.27 mm) pitch with vertical SMT mounting, delivering the highest contact count in a compact footprint for board-to-board applications
- H (high profile) body height option provides additional clearance above the PCB surface for cable routing or component placement near the connector
- Leave-clearance (LC) design enables post-reflow solder joint inspection beneath the connector body, supporting IPC-class quality verification for high-reliability assemblies
What is TFM-146-02-H-D-LC used for?
The TFM-146-02-H-D-LC is optimized for high pin-count board-to-board interconnects in FPGA mezzanine systems, embedded computing backplanes, and advanced communications infrastructure where 92 contacts at 1.27 mm pitch are needed in a minimal PCB area. Its high-profile body suits applications where routing space above the connector is beneficial, such as multi-layer PCB assemblies in defense electronics and signal processing platforms. The connector is also deployed in high-channel-count data acquisition, medical imaging, and industrial automation systems requiring dense SMT interconnects.

Frequently Asked Questions
What is the total contact count and pitch of the TFM-146-02-H-D-LC and how are contacts arranged?
The TFM-146-02-H-D-LC has 92 total contacts in a dual-row SMT configuration with 46 contacts per row at 0.050 inch (1.27 mm) pitch. This high-density arrangement supports 92 independent signal channels on a compact PCB footprint, making it well-suited for FPGA mezzanine cards and high pin-count board-to-board interconnect applications.
What does the H designator in TFM-146-02-H-D-LC indicate and when should engineers select this option?
The H designator specifies a high-profile body height variant, providing additional vertical clearance above the PCB surface compared to the standard-height version. Engineers should select the H option when components or cable harnesses need to pass over or alongside the connector on a board assembly, which is common in multi-layer PCB designs with 92-contact dense routing in defense or communications equipment.
How does TFM-146-02-H-D-LC compare to similar 92-position connectors at 2.54 mm pitch?
At 1.27 mm pitch, the TFM-146-02-H-D-LC occupies roughly half the PCB length compared to an equivalent 92-contact connector at 2.54 mm pitch, enabling significantly denser board designs. The Tiger Eye dual-beam contacts also provide higher reliability and better signal integrity at high frequencies compared to standard single-beam contacts used in many 2.54 mm pitch alternatives.
Where can TFM-146-02-H-D-LC be purchased and what quantities are typically available?
The TFM-146-02-H-D-LC can be purchased through SAMTEC authorized distributors worldwide, including major electronics distributors serving the Americas, Europe, and Asia Pacific. Stocked quantities for this 92-position, 1.27 mm pitch SMT connector typically range from individual units for prototyping to reel quantities of 500 or more for production orders, with most distributors offering same-day shipping for available stock.
