It is rated for under-hood and cabin modules where the ambient temperature hits 105°C and the clock must stay within ±10 ppm of 148.5 MHz — think ADAS camera serializers, automotive Ethernet PHYs, or infotainment SerDes links. Supply voltage spans 1.7V to 3.6V, so it can run directly from a 1.8V or 3.3V rail without an external LDO. ## Package, footprint, and board-level fit Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm.","metaTitle":"DSC1003DL5-148.5000T – 148.5 MHz MEMS XO, AEC-Q100, ±10 ppm","metaDescription":"Microchip DSC1003DL5-148.5000T: 148.5 MHz MEMS oscillator, AEC-Q100, ±10 ppm stability, -40 to 105°C, 1.7-3.6V supply, 9.6 mA max.

That means it has passed automotive-grade reliability stress tests including temperature cycling, ESD, latch-up, and extended life — suitable for under-hood and cabin modules where ambient temperature reaches 105°C."},{"question":"Can DSC1003 be used as a drop-in replacement for DSC1002?","answer":"The evidence does not confirm pin-compatibility between DSC1003 and DSC1002. Both are 4-SMD no-lead MEMS oscillators from Microchip, but the electrical specifications (supply range, stability, output type) may differ. Verify the land pattern and electrical ratings against your BOM before substituting."},{"question":"Is the DSC1003 series RoHS compliant?","answer":"The evidence does not explicitly list RoHS compliance. However, as an active Microchip product in a standard 4-SMD package, it is reasonable to expect RoHS compliance — confirm on the latest datasheet or certificate of compliance from Microchip."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1003DL5-148.5000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1003DL5-148.5000T when reusing this data.
