The FCI 10037402-11127LF is a 240-position FB-DIMM (Fully Buffered Dual In-Line Memory) connector designed to accept DDR2 FBDRAM modules on a server or storage backplane. The FB-DIMM form factor positions this connector squarely in high-computing infrastructure — it is not a standard DDR2 DIMM slot; the fully buffered architecture routes memory traffic through an advanced memory buffer (AMB) on the module, placing higher signalling demands on the slot than a commodity desktop DIMM. With 240 positions it matches the full-width FB-DIMM module density used in Intel-based and other enterprise server platforms. Contacts are gold-plated at 15.0 µin (0.38 µm) — a thickness that supports multiple insertion cycles without the fretting risk thinner tin finishes carry on high-cycle server maintenance. The through-hole mounting and the board-lock + latch retention scheme hold the module firmly under the vibration and thermal cycling encountered in rackmount chassis. The MO-256 standard governs the slot geometry and keying — confirming the 10037402-11127LF is dimensionally matched to compliant FB-DIMM modules from any AMB vendor. Top-mount orientation (Normal, Standard) means the module inserts from the chassis top, which governs the PCB stack-up and keep-out zone around the slot.
What the key ratings mean for your fit decision
240 positions is the defining number — the board layout must have a 240-contact pad array matched to the MO-256 footprint. Any deviation in position count or pitch class means a non-interoperable module. The gold plating at 15.0 µin (0.38 µm) is the key durability spec: it tells you this connector is built for repeated module swaps in field service rather than a single-installation-only role. Board locks on the connector body anchor it to the PCB during insertion/removal cycles, which matters when a technician is pulling a failed FBDRAM module in a live chassis.
Sourcing and lifecycle
Listed Active with tray packaging — quoted to order against BOM quantity. DDR2 FBDRAM is a mature platform; the 10037402-11127LF sits in the established product tree under base number 10037402. No official successor or cross-reference appears in the ledger — confirm the exact position count and MO-256 compliance against your module vendor's datasheet before committing. Sourced per RFQ.
