Key Features
- 98-position dual-row layout on 0.050" (1.27 mm) pitch for maximum contact density in compact SMT mezzanine and board-to-board designs
- Gold-plated contacts with 1 A per-pin current rating ensuring low contact resistance and long-term reliability
- Wide operating temperature from -55°C to +125°C suitable for industrial, telecom, and aerospace PCB interconnect applications
Applications
The SFM-149-02-SM-D-A serves high-density board-to-board and mezzanine interconnect applications in telecommunications infrastructure, industrial control systems, and embedded computing platforms. With 98 contacts in a dual-row 0.050" pitch footprint, the connector enables data, power, and ground distribution across stacked PCBs in tight enclosures. Its gold-contact construction and broad thermal range make it reliable in server blades, network line cards, and ruggedized control modules.

Frequently Asked Questions
How many contact positions does the SFM-149-02-SM-D-A offer, and what pitch separates adjacent pins?
The SFM-149-02-SM-D-A provides 98 contact positions in a dual-row arrangement with 0.050" (1.27 mm) pitch between centers. This fine pitch supports very high contact counts in a footprint roughly half the length of equivalent 0.100" pitch connectors, making it ideal for dense mezzanine and board-stacking designs where PCB real estate is critical.
Which alternative Samtec SFM series part would suit a design needing only 78 positions instead of 98?
For a 78-position requirement with the same 0.050" pitch dual-row surface-mount format, the SFM-139-02-H-D-A is the closest alternative. Both parts share identical pitch, row count, and gold-contact 1 A per-pin current rating, so footprint migration between the two parts requires only a minor PCB pad change at the connector location without any routing layer changes.
Can the SFM-149-02-SM-D-A be used in equipment cycling between -40°C cold storage and +85°C operating conditions?
Yes. The SFM-149-02-SM-D-A is rated from -55°C to +125°C, which fully encompasses the -40°C to +85°C industrial temperature cycling range. Gold-plated contacts maintain stable contact resistance across the full range, and the surface-mount solder attachment withstands the thermal expansion stress associated with repeated temperature excursions in field-deployed industrial equipment.
