What are the key features of SFM-142-02-S-D-DS?
- 84-position dual-row layout at 0.050" (1.27 mm) pitch providing high signal density in a compact surface mount footprint
- Dual-segment (DS) body design splits the connector into two shorter sections, improving coplanarity and solder joint reliability
- Tiger Eye contact technology delivers elevated normal contact force for gas-tight, vibration-resistant electrical connections
- Surface mount termination enables standard SMT reflow assembly without through-hole drilling for 84 contacts
- High-reliability socket strip design suitable for industrial, defense, and aerospace board-to-board stacking applications
What is SFM-142-02-S-D-DS used for?
The SFM-142-02-S-D-DS is designed for high-density board-to-board mezzanine connections in FPGA expansion boards, industrial computing modules, and defense avionics assemblies requiring 84 reliable signal positions at 0.050" pitch. The dual-segment body improves PCB coplanarity for fine-pitch SMT soldering, making it particularly valuable for large-format signal boards where connector bow or warp could compromise solder joint integrity across all 84 positions. Its Tiger Eye contacts ensure consistent performance across temperature ranges from -55°C to +125°C for mission-critical electronics.

Frequently Asked Questions
How many positions does the SFM-142-02-S-D-DS provide, and how are they distributed in its dual-row layout?
The SFM-142-02-S-D-DS provides 84 positions arranged in a dual-row configuration at 0.050" (1.27 mm) pitch, with 42 contacts per row. This 84-position density is used in applications such as FPGA I/O expansion connectors, embedded processor interface boards, and high-channel-count data acquisition systems where routing 42 signals per row in a single surface mount connector minimizes the number of connector sites on a densely populated PCB.
What does the DS suffix mean in SFM-142-02-S-D-DS, and why does a dual-segment body improve assembly quality?
The DS suffix in SFM-142-02-S-D-DS denotes a dual-segment body, meaning the connector housing is divided into two physically separate sections rather than a single monolithic body. This segmented design significantly reduces the risk of connector bow or warp across the length of an 84-position 0.050" pitch connector during SMT reflow, which keeps all contact tails coplanar with the PCB surface and improves solder joint consistency across all 84 positions — a critical advantage on boards with tight solder paste stencil tolerances.
Is the SFM-142-02-S-D-DS suitable for vibration-prone environments, and what temperature range does it support?
Yes. The SFM-142-02-S-D-DS uses SAMTEC's Tiger Eye contact technology, which provides a higher than standard normal contact force at the mating interface, ensuring stable gas-tight electrical connections under mechanical vibration and shock. This design is validated for operating temperatures from -55°C to +125°C, making the connector appropriate for industrial machinery, ruggedized embedded computing, military ground vehicles, and aerospace avionics boards where both wide temperature cycling and vibration endurance are required.
Which mating plug connectors are compatible with the SFM-142-02-S-D-DS, and how should designers select the correct stack height?
The SFM-142-02-S-D-DS mates with SAMTEC dual-row plug headers in the TSM, FLE, and THM series at the same 0.050" (1.27 mm) pitch. Designers should select the mating plug based on the required board-to-board stack height, which is typically specified in millimeters ranging from 4 mm to 20 mm depending on the connector variant. SAMTEC's online Connector Configurator allows filtering compatible 84-position dual-row plugs by stack height for both standard and low-clearance mating options.
When would a PCB designer choose the SFM-142-02-S-D-DS over a single-segment SFM socket of equivalent position count?
A designer would choose the SFM-142-02-S-D-DS dual-segment variant over a single-segment SFM socket when connector length and reflow-induced warping are concerns. For long 84-position connectors at 0.050" pitch, a single-body connector can bow by tens of micrometers during reflow, causing solder bridging or open joints at the contact tails. The DS dual-segment body limits the effective unsupported span to roughly half, reducing bow and improving coplanarity to within the 0.1 mm tolerance required by fine-pitch SMT assembly processes.
