This is compatible with the Bill of Materials quick entry on Mouser. Though an account is not needed for ordering on Mouser, one is needed to use this feature. But anyone can sign up (don't need to be a business), so why not? Makes part entry a breeze as you can just cut-n-paste. Additionally, you can quickly see what Mouser has out of stock. It covers parts on page one only. Note: The CD15 Silver Mica caps can sometimes be subbed with the slightly smaller CD10, eg 5982-15-500V27 --> 5982-10-500V27 Also, the footprints are pretty tight on this board, so pay attention to any electrolytic substitution - it may either not fit or not allow for a 2" high chassis. 11/30/08 - -Filament dropping resistors at R36 and R37 have been removed. Just use cut resistor leads as jumpers at these locations. -Subs due to back order at this time: 71-CW2B-470 with 72-RWM410-470-5 281-33K-RC with 261-33K-RC 71-RN65D-F-47.5K 2 71-RN60D-F-475K 6 71-RN65D-F-1.27K 2 71-RN65D-F-301K 2 281-27K-RC 2 281-33K-RC 2 72-RWM410-470-5 4 71-RN65D-F-1.0K 4 72-T93YB-10K 4 594-5083NW330K0J 1 72-T93YB-100K 2 72-RWM410-3K3-5 2 72-RWM410-100-5 4 71-RN65D-F-150K 2 527-CL90 1 71-RN60D-F-10 4 75-715P400V0.1 4 647-UVR1V471MPD 4 5985-380-450V121 4 5982-15-500V27 2 5982-15-500V33 2 5982-15-500V15 2 5989-250V.22-F 2 UF4007-E3/54 2 571-114376644 1 571-14376645 4 571-14376644 2
