Product details

Obsolete MEMS oscillator – sourcing path for existing BOMs

DSC6003JI2A-048.0000 is officially listed as Obsolete by Microchip Technology. For existing designs that require this exact frequency, package, and automotive qualification, the only sourcing channel is independent distribution.

48 MHz MEMS timing with AEC-Q100 grade

Supply voltage spans 1.71 V to 3.63 V, allowing direct connection to 1.8 V, 2.5 V, or 3.3 V rails without an external regulator.

Package footprint and board layout note

Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits tight timing reference slots on automotive ECU or sensor PCBs. Surface-mount assembly requires standard reflow profiles for no-lead packages. The small body means solder paste volume and stencil aperture should be verified to avoid tombstoning or insufficient fillet.

Frequently asked questions

What is the replacement for DSC6003JI2A-048.0000?

Microchip has not published a direct pin-compatible successor for this order code. Any replacement would require a new oscillator selection with matching frequency (48 MHz), package (4-SMD no-lead), supply range (1.71-3.63 V), and AEC-Q100 qualification. A board spin or layout change may be necessary.

What is the frequency stability of DSC6003JI2A-048.0000?

±25 ppm over the full -40°C to 85°C operating range. This stability includes initial tolerance, temperature drift, and aging effects.

Does DSC6003JI2A-048.0000 have an enable/disable function?

Yes. The Enable/Disable pin allows the output to be gated. When disabled, the oscillator core may still be powered, reducing dynamic current draw while maintaining fast start-up.
