Attachment C_Bill of Materials for RFQSSPR452058.pdf

This is a Bill of Materials document for federal contract opportunity RFQSSPR452058. The document specifies seven line items required for procurement, primarily consisting of cryogenic cooling system components manufactured by Sumitomo. The required items include: a 4K 1.5 watt cold head (RDK-415E2/XRD44Z1019), an F-70H compressor module rated at 200 PSIG for 4KGM systems (268072A1), a power cord with 90-degree connectors and 5mm rings (267383C10), two stainless steel hose assemblies measuring 3/4 inch diameter by 65 feet in length (266950B65), a cable assembly connecting the 4KGM cold head to the F-70 compressor (267632C66), and a complete 4K system installation kit (267990A). Item 7 indicates a tariff provision with the option for a domestic equivalent supplier.

The document explicitly allows for domestic equivalent products as an alternative to the specified Sumitomo manufacturer parts, providing flexibility for suppliers to propose comparable domestic alternatives. The total quantity requirements are modest, with quantities ranging from one to two units per line item, indicating a specialized procurement for specific technical applications rather than high-volume acquisition.
