THEMIS Instrument PDRParts- 6 UCB, October 15-16, 2003 EEE Parts List - I UCB/SSL QA will maintain an EEE Parts Identification List (PIL) The PIL will contain: Manufacturer’s generic part number Military Part Number or SCD number Manufacturer(s) Where used (unique assembly) / Quantity Quantity used Quantity ordered Lot/Date Code Radiation Status (TID/SEL) Alert Status Comments

THEMIS Instrument PDRParts- 7 UCB, October 15-16, 2003 EEE Parts List – II (continued) Parts will be procured to an approved Parts List. -Schedule permitting, will procure common buy. -Procurement of devices will be based upon design engineer’s confidence-of-use factor of 70%. -Unique, high-dollar items will be based on a 90%-100% confidence level. -Minimum Attrition / Spares factor of 20%-30% will be applied to flight procurement quantities. Non-standard devices will have more spares. -Schedule and cost permitting, engineering test units (ETU) will use flight qualified parts, especially, where minimum buy quantities are imposed. ETU and Flight unit -Procurement will run concurrently

THEMIS Instrument PDRParts- 8 UCB, October 15-16, 2003 EEE Parts List – III (continued) Flowdown Performance Assurance Implementation Plan (PAIP) requirements on subcontractors Parts Control Board (PCB) PCB members are: Themis QA, Design Engineer, and Themis Project manager, or representative PCB shall review EEE part for: -Testing, Screening, and Qualification Failures -Alerts (e.g., GIDEP) -Review Non-Standard Parts Requirements
