DC/DC CONVERTERS

PR 1300924837

DESCRIPTION OF REQUIREMENT:

The Naval Undersea Warfare Center Division, Newport (NUWCDIVNPT), requires DC-DC Converters to fix major line replaceable units (LRUs) in

The DC-DC Converters have a 72-week lead-time with the required delivery date of 1 December 2022. Anticipated total value is

MFG Part Number Description / Title Quantity G608321-1 Rev. F DC/DC Power Convertor 20 each G608321-2 Rev. F DC/DC Power Convertor 10 each G608321-3 Rev. F DC/DC Power Convertor 10 each G608321-4 Rev. F Ripple Attenuator Module 20 each

SOLE SOURCE JUSTIFICATION:

The DC-DC Converter is a sub-component of the Power Supply, Power Module which is a Raytheon manufactured part, number G608321. Assurance Technology Corporation (ATC) Power Systems is the original equipment manufacturer (OEM) of the DC-DC Converter which are the direct replacement parts to support repair of SubHDR mast LRU CCAs. ATC is the only qualified and approved source of supply listed on Raytheon controlled drawing # G608321. The part has limited applications due to the unique nuclear hardening requirements that the supplier has designed and certified the parts to.

In order to release a competitive Request for Quote, NUWCDIVNPT, would have to collaborate with Raytheon and to certify/approve additional vendors to produce this part, which is crucial for SubHDR’s uninterrupted operation. Based on previous obsolescence related design tasks under taken by Raytheon, the Government estimates that the certification / approval process will take forty-eight (48) months and cost , as detailed in the table below. The additional costs and time associated with qualifying additional vendors for this timesensitive acquisition would be impractical to pursue.
