The DSC1001BL5-050.0000T: There is no last-time-buy window to plan around — production orders can be placed without qualification of a backup source.
AEC-Q100 qualification — what grade, exactly?
That places it in the Grade 1 ambient temperature band — the same band an under-hood ECU sees on a hot summer grade. Capable is not qualified; this part carries the AEC-Q stamp, so the OEM auditor will accept the PPAP documentation without a waiver request.
50 MHz CMOS output over a wide supply rail
This XO delivers a 50 MHz CMOS clock from a MEMS resonator across a 1.8V to 3.3V supply range. The wide voltage tolerance means one BOM line covers 1.8V MCU domains and 3.3V CAN transceivers without a separate oscillator variant.
Footprint and board-level fit
The 4-SMD, No Lead package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm. Surface-mount reflow follows standard lead-free profiles; the MEMS die is sealed inside the package, so no special bake-out or moisture sensitivity handling is required beyond the standard MSL level.
