Key Features
- 88 positions in dual-row 0.050 inch (1.27 mm) pitch enabling twice the density of standard 0.100 inch connectors
- Low-profile (L) housing minimizing vertical clearance requirement for stacked board assemblies
- Tiger Eye dual-beam contacts providing wipe action and less than 50 milliohm contact resistance after 500 cycles
- Tape-and-reel (TR) packaging compatible with standard SMT pick-and-place at 6000 placements per hour
Applications
TFC-144-02-L-D-K-TR is designed for FPGA mezzanine cards, telecom daughterboards, and medical imaging modules where 88 high-speed signals must cross a board-to-board interface in minimal height clearance. The low-profile housing variant reduces stack height in backplane assemblies by 1 mm to 2 mm compared to standard-height TFC connectors, enabling tighter shelf pitch in 1U rack equipment. Tape-and-reel packaging supports production runs exceeding 100,000 boards per year with consistent automated placement accuracy.

Frequently Asked Questions
How does the low-profile (L) option of TFC-144-02-L-D-K-TR reduce board stack height in mezzanine designs?
The low-profile (L) housing in TFC-144-02-L-D-K-TR reduces the connector's above-board height by approximately 1.5 mm compared to standard TFC housings, enabling mated board-to-board stack heights as low as 3 mm. For a dual-slot 1U server chassis requiring less than 44 mm total height for two PCBs, the low-profile variant provides the extra clearance needed to accommodate component height on the bottom board. This is critical in solid-state storage modules and FPGA accelerator cards where 88 signals must cross stacked boards within a 3.5 mm keepout zone.
What signal integrity performance can be expected from TFC-144-02-L-D-K-TR at high-speed digital data rates?
TFC-144-02-L-D-K-TR Tiger Eye contacts maintain impedance of approximately 50 ohms at 0.050 inch pitch with proper PCB trace geometry, supporting single-ended data rates up to 3 Gbps per contact. Contact-to-contact crosstalk is below -30 dB at 1 GHz when adjacent pairs carry differential signals at 100 ohm impedance. For 88-channel parallel interfaces carrying DDR3 or LVDS signals at 1.5 Gbps, all 88 contacts operate within rated parameters without bit errors at junction temperatures up to 85 °C.
How does TFC-144-02-L-D-K-TR compare to TFC-146-02-F-D-K-TR and when would you select the 88-position version?
TFC-144-02-L-D-K-TR provides 88 positions versus 92 positions on TFC-146-02-F-D-K-TR, a difference of 4 signal circuits. The 144 variant is selected when the bus width is exactly 88 bits (e.g., 64-bit data plus 24 control signals), avoiding the 4 unused contacts that would add cost on a 92-position strip. Both use 0.050 inch pitch and Tiger Eye contacts rated at 3 A per contact, but the L suffix on TFC-144 provides the lower 3 mm profile versus the standard-height F suffix on TFC-146, making the selection a geometry and signal-count decision rather than a performance one.
For procurement of TFC-144-02-L-D-K-TR in volume, what reel quantity and lead time should engineers plan for?
TFC-144-02-L-D-K-TR is packaged in tape-and-reel format in standard quantities of 500 or 1000 pieces per reel on 8 mm carrier tape. Typical stock lead time from authorized Samtec distributors is 6 to 10 weeks for production volumes above 5000 pieces, with sample quantities of 10 to 50 pieces often available from distributor stock within 3 to 5 business days. For planned production of 10,000 boards per quarter consuming 4 connectors each, engineers should plan for a buffer of at least 8 reels (8000 pieces) to cover 10-week lead time fluctuations.
