Key Features
- Right-angle receptacle orientation enables board stacking at 90 degrees for space-constrained orthogonal PCB configurations
- 50-position dual-row layout on .050-inch pitch delivers high signal density in a compact 1.375-inch body length
- RoHS-compliant Pb-free construction with 1-week factory lead time supports fast-turn assembly schedules
Applications
The TFML-125-01-S-D-RA is used in right-angle daughter-card and mezzanine board assemblies where a perpendicular PCB orientation saves enclosure depth. Its 50-position, .050-inch pitch dual-row format is well-suited for embedded computing modules, test adapters, and industrial I/O expansion cards that need orthogonal board-to-board interconnect with a low-profile, surface-accessible receptacle.

Frequently Asked Questions
Why would an engineer choose the right-angle orientation of TFML-125-01-S-D-RA over a vertical board stacking receptacle?
The right-angle orientation of TFML-125-01-S-D-RA allows a daughter card to mount perpendicular to the motherboard, reducing the overall assembly height by routing the 50 positions at 90 degrees. This is critical in shallow enclosures where a vertical mezzanine card would exceed the available Z-height clearance above the .050-inch pitch receptacle.
What body dimensions should a PCB layout engineer account for when placing TFML-125-01-S-D-RA on a board?
The TFML-125-01-S-D-RA has a body length of 1.375 inches, breadth of 0.225 inch, and depth of 0.29 inch. These dimensions define the keep-out zone around the connector footprint, and the right-angle exit direction requires a clear routing channel perpendicular to the board edge for the mating header to engage the 50-position dual-row contacts.
How does the 1-week factory lead time of TFML-125-01-S-D-RA compare to other high-density SAMTEC stacking connectors for prototype builds?
With a factory lead time of 1 week, TFML-125-01-S-D-RA is among the faster-shipping options in SAMTEC's .050-inch pitch board stacking family, making it practical for prototype and small-batch production schedules. Many higher-performance SAMTEC mezzanine connectors carry lead times of 4 to 6 weeks, so TFML-125-01-S-D-RA is preferable when timeline is the primary constraint and 50-position capacity is sufficient.
