The part is officially marked obsolete by Microchip. For new designs or replacement on existing BOMs, the sourcing path is through independent distribution — quantities confirmed at RFQ, no factory lead time. ## Standby mode and supply flexibility The wide supply range (1.71V–3.63V) covers both 1.8V and 3.3V logic domains without a level translator on the clock input. Maximum current draw is 1.3 mA typical, making it a low-power choice for always-on automotive modules even before the standby feature engages. Housed in a 4-SMD, no-lead package measuring 1.60 mm x 1.20 mm with a seated height of 0.89 mm. The small footprint suits space-constrained automotive modules like key fobs, camera modules, or telematics controllers.","metaTitle":"DSC6001HE1A-018.4320T MEMS XO, 18.432 MHz, AEC-Q100","metaDescription":"Microchip DSC6001HE1A-018.4320T MEMS XO, 18.432 MHz, CMOS output, 1.71-3.63V, AEC-Q100, obsolete.

It is available through independent distribution — submit an RFQ with your target quantity and we will confirm lot-specific availability and pricing. No stock-holding claim is made; sourcing is confirmed per order."},{"question":"What replaces DSC6001HE1A-018.4320T?","answer":"Microchip has not listed an official direct-replacement order code in the DSC60XX series for this specific frequency and package. For a pin-compatible MEMS XO at 18.432 MHz with AEC-Q100 and standby, check the DSC6001 series active variants — the datasheet covers the full family. Alternatively, a quartz-based oscillator in the same 4-SMD footprint can serve as a functional substitute, but verify the supply voltage range and output type match."},{"question":"Does DSC6001HE1A-018.4320T have a standby mode?","answer":"Yes, the function is listed as Standby (Power Down). When the enable pin is driven low, the oscillator stops and draws minimal current — suitable for sleep-mode power gating in automotive or portable designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC6001HE1A-018.4320T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC6001HE1A-018.4320T when reusing this data.
