Microchip lists the DSC1033CI2-012.2880 as Obsolete. No official successor part number is published, but the DSC1033 series remains available in other frequency/temperature variants — a pin-compatible replacement with the same 4-SMD no-lead footprint and 3.3V supply can be selected from the active DSC1033 family. Housed in a 4-SMD no-lead package measuring 0.126\" × 0.098\" (3.20 mm × 2.50 mm) with a seated height of 0.035\" (0.90 mm). The small footprint suits space-constrained PCBs in portable or densely populated designs.","metaTitle":"DSC1033CI2-012.2880 MEMS XO 12.288 MHz CMOS Obsolete –","metaDescription":"DSC1033CI2-012.2880 XO (Standard) MEMS oscillator, 12.288 MHz, CMOS output, 3.3V, ±25 ppm, -40°C to 85°C.

It is sourced through independent surplus channels — submit an RFQ with your target quantity and we will confirm availability and current pricing. No stock-holding claim is made; every order is quoted to order."},{"question":"What is the direct replacement for DSC1033CI2-012.2880?","answer":"Microchip has not published a specific direct replacement. However, the active DSC1033 series includes other 12.288 MHz variants in the same 4-SMD no-lead package and 3.3V supply — for example, a ±25 ppm industrial-temperature part with the same standby function. Check the DSC1033 family datasheet for available order codes; the pinout and footprint are identical across the series."},{"question":"Does DSC1033CI2-012.2880 support a standby power-down mode?","answer":"Yes. The function is listed as Standby (Power Down). When disabled, the supply current drops to 1 µA max, and the output goes high-impedance. This makes it suitable for battery-powered designs that need to conserve power between active periods."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033CI2-012.2880","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033CI2-012.2880 when reusing this data.
