What are the key features of TSM-138-04-F-DV-P-TR?
- 76-position dual-row SMT layout on 0.100" (2.54 mm) pitch supports parallel bus, mixed-signal, and power distribution in a single compact connector
- Tape-and-reel (-TR) delivery enables seamless integration into automated pick-and-place lines at volumes exceeding 1,000 units per run
- Surface-mount termination eliminates through-hole drilling, reducing PCB layer costs and enabling component placement on both board surfaces
What is TSM-138-04-F-DV-P-TR used for?
The TSM-138-04-F-DV-P-TR is used in motherboard-to-daughtercard stacking and dense backplane signal interconnects in industrial controllers, embedded computing modules, and telecommunications line cards. Its 76-position 2.54 mm pitch dual-row SMT format is well-suited for FPGA development boards and DSP systems where parallel 32-bit to 64-bit data buses plus power and ground rails must route through a single high-density surface-mount connector.

Frequently Asked Questions
What differentiates the TSM-138-04-F-DV-P-TR from the TSM-138-03-F-DV-P-TR variant?
Both parts share the same 76-position dual-row 0.100" (2.54 mm) SMT footprint, but the -04- designator indicates a different plating or post length variation within SAMTEC's TSM series. Selecting the correct variant ensures the proper stack height and contact engagement depth for a given mating receptacle, which directly affects normal contact force and the maximum number of reliable mating cycles over the product's lifetime.
What bus widths can a 76-position dual-row terminal strip support in FPGA board designs?
A 76-position dual-row strip at 2.54 mm pitch can carry a 32-bit data bus with associated address, control, clock, and power signals in a single connector, or a full 64-bit data bus when power and ground pins are shared across both rows. At 2.54 mm pitch, the 76-pin connector spans approximately 48 mm in length, fitting within the edge profile of standard Eurocard (100 mm × 160 mm) or half-size FPGA boards.
How does the SMT design of the TSM-138-04-F-DV-P-TR improve signal integrity compared to through-hole terminal strips?
The SMT termination reduces lead length to under 1 mm, cutting parasitic inductance per pin to less than 1 nH compared to 5–10 nH for through-hole leads. This improvement benefits high-speed signals above 100 MHz on parallel buses, reducing reflections and crosstalk on the 76 contacts. The shorter stub also allows the PCB stackup to maintain controlled 50-ohm impedance traces beneath the connector footprint.
What mating connectors from SAMTEC are compatible with the TSM-138-04-F-DV-P-TR?
The TSM-138-04-F-DV-P-TR is designed to mate with SAMTEC's SFM, TFM, and SHF series dual-row receptacle strips on the same 0.100" (2.54 mm) pitch. Mating configurations support board-to-board stack heights from approximately 8 mm to over 20 mm, depending on the selected receptacle series, providing design flexibility for varying PCB separation requirements in multi-board assemblies.
