What are the key features of SFM-104-T2-ZZ-D-A-K-TR?

  • Dual-row 8-position socket strip with 0.050" (1.27 mm) pitch for compact high-density board-to-board signal routing
  • ZZ (zero insertion force-style) end configuration enabling daisy-chain or stacking assembly of multiple SFM connectors on adjacent PCBs
  • High-reliability gold-plated contacts providing low contact resistance and resistance to oxidation for extended service life in demanding applications

What is SFM-104-T2-ZZ-D-A-K-TR used for?

The SFM-104-T2-ZZ-D-A-K-TR is designed for high-density board-to-board stacking applications in embedded computing modules, FPGA development boards, and high-reliability industrial control systems using the SAMTEC SFM series 1.27 mm pitch interface. Its ZZ end configuration supports end-to-end daisy-chain assembly, making it suitable for scalable mezzanine card architectures where multiple connector segments are aligned along a single edge. This connector is also used in test-and-measurement systems and defense electronics requiring repeatable 8-position signal connectivity.

Frequently Asked Questions

What does the ZZ suffix indicate in the SFM-104-T2-ZZ-D-A-K-TR part number?

The ZZ suffix in the SFM-104-T2-ZZ-D-A-K-TR designates the end configuration of the connector housing, which supports end-to-end daisy-chain assembly of multiple SFM connectors placed adjacently on a PCB. This allows designers to scale a 1.27 mm pitch, dual-row interface beyond 8 positions by aligning multiple connectors along a row.

How does SFM-104-T2-ZZ-D-A-K-TR compare to SFM-104-T2-H-D-A-K-TR for a stacking mezzanine card design?

The SFM-104-T2-ZZ-D-A-K-TR uses the ZZ end option that removes material at one or both ends for end-adjacent placement, enabling seamless connector-to-connector stacking in a 1.27 mm pitch interface. The SFM-104-T2-H-D-A-K-TR uses the H end option with standard housing ends, which is better for standalone 8-position single-connector placements where daisy-chaining is not needed.

What board-to-board stack height range is achievable with the SFM-104-T2-ZZ-D-A-K-TR and its mating header?

The achievable stack height between boards using the SFM-104-T2-ZZ-D-A-K-TR and its SAMTEC mating header depends on the selected header pin length. Typical SAMTEC SFM-compatible mating headers support inter-board spacing from approximately 4 mm to 15 mm, with the specific height set by the complementary TSW or TFW series header variant chosen.

When is it preferable to use SFM-104-T2-ZZ-D-A-K-TR over a higher position-count SFM connector in a data bus design?

Using multiple SFM-104-T2-ZZ-D-A-K-TR 8-position connectors in a ZZ daisy-chain is preferable to a single large connector when the data bus requires flexibility to add or remove connector segments, or when PCB routing constraints prevent placing a single long connector spanning more than 8 positions at 1.27 mm pitch in a constrained layout area.
