| Legacy programs | End-of-life and hard-to-find component sourcing |
| Supply continuity | Lifecycle transition and long-term availability support |
| Quality requirements | Traceable sourcing and quality-management processes |
FPGAX focuses on helping customers maintain access to critical programmable devices throughout the full component lifecycle. Whether the requirement is for a current design, an established production program, or an older platform facing component obsolescence, our goal is to provide a stable sourcing path and help customers maintain design and manufacturing continuity.
Yes. FPGAX supports sourcing for both active components and end-of-life or hard-to-find parts, with an emphasis on maintaining supply continuity for engineering and manufacturing programs.
Our core sourcing coverage includes major FPGA and programmable logic manufacturers such as Xilinx, Intel/Altera, Lattice, Microchip, and QuickLogic, subject to specific part requirements and availability.
We support customers through lifecycle transitions by helping locate current or legacy supply, reducing exposure to supply disruptions, and supporting long-term availability for designs that need to remain in production.
FPGAX states certification to AS9120B, ISO 9001:2008, and ISO 14001 standards. Our sourcing services are structured around traceability, stable supply, and quality-management requirements.
Providing the manufacturer part number, required quantity, target delivery schedule, and any lifecycle or traceability requirements helps us evaluate the sourcing request more efficiently.
