HDBK-103AC, DEPARTMENT OF DEFENSE HANDBOOK: LIST OF STANDARD MICROCIRCUIT DRAWINGS (25 SEP 2008)., The Standard Microcircuit Drawing Program (SMDP) is directly under the auspices of the DoD Parts Management Program (PMP). The PMP is implemented by MIL-HDBK-512, "Parts Management." The PMP will be the avenue for screening candidate parts for the SMDP by the DSCC Military Parts Control Advisory Group (MPCAG).
