Amendment 3

Question 8: A vendor identified part: 8217426 Logic Board, 743C083102JTR, RESISTOR ARRAY, CHIP, 4 ISOLATED, 1K OHMS, 5%, 0.1W as obsolete and unavailable.

Response: An equivalent part can be used. The company can propose an alternate part as long as it has been brought to the attention of the Government in the quote. The Government will review the proposed parts and approve if it meets the salient specifications. For the specific part identified in this question the Government has identified 743C083102JP as a direct replacement. It is a lead free variant of the original part.

For reference, the salient features of the part are called out in datasheet of the part. Parts must meet form/fit and function to be equivalent. For example, for this part it must meet:

Circuit Type: Isolated Resistance (Ohms) : 1k Tolerance: 5% Number of Resistors : 4 Number of Pins: 8 Power Per Element: 100mW Operating Temperature: -55C ~ 125C Mounting Type: Surface Mount Supplier Device Package: 0805 Size / Dimension: 0.200" L x 0.079" W (5.08mm x 2.00mm)

Question 9: We cannot identify 8217429 CONVERTER / AMPLIFIER BOARD ASSEMBLY, 53711-5992986, TRANSFORMER, 1:1.3:1.3; No manufacturer is listed.

Response: The transformer referenced in the drawing is the same as the one in the parts list for the convertor amp board. Drawing calls out specifications of the part needed on the amp board.
