The DSC1033BI1-025.0000: Available through independent surplus channels. Quantities are lot-specific, and condition (sealed reel vs. cut tape) is confirmed at RFQ. No official successor is listed from Microchip.
Housed in a no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. Typical supply current is 3 mA during active operation, rising to the 3 mA max figure at full load. The disable current of 1 µA ensures negligible battery drain in standby.
Since the part is obsolete, engineers and buyers need a pin-to-pin or functional equivalent to avoid redesign.
Buyers need to find authorized distributors with real stock and competitive pricing to fulfill BOM lines.
Lifecycle status determines whether to source remaining stock, find an alternative, or plan for end-of-life.
Design engineers must verify pin compatibility with PCB layout before substituting the oscillator into a design.
CMOS output vs. other logic levels ensures signal compatibility with the downstream device.
The standby function affects power management in battery-operated designs and must match the application requirement.
