NCV2903DR2G is an onsemi AEC-Q100 qualified dual comparator in SOIC-8, tape and reel — the automotive-grade version of the classic LM2903/LM393 architecture. 2 V to 36 V single-supply (or ±1 V to ±18 V dual) operation with open-collector outputs, 1.3 µs propagation delay, 250 nA input bias current, 7 mV offset and −40 °C to +125 °C temperature range. The automotive qualification is the selection point: the same threshold-detection, zero-crossing and oscillator circuits engineers already know from the LM393, but rated and qualified for under-hood and body electronics where a commercial comparator cannot go. Selection advice: the NCV prefix is the automotive line — for pin-compatible commercial designs use the LM393/LM2903 family; DR2G denotes SOIC-8 tape and reel (2500/reel). Open-collector outputs need pull-up resistors and can be wire-ORed across channels. Evidence: Mouser, DigiKey and Future Electronics listings confirm 2–36 V, dual open-collector, AEC-Q100, SOIC-8 and Active status. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
NCV2903DR2G is a Dual comparator from onsemi, orderable in the SOIC-8 package. The ordering code fixes the exact configuration you receive — package, grade and packing — so procurement starts with matching this code character-for-character against your BOM, not just the base series name.
When you request a quote, include the full ordering code, the target packing format (reel, tube, tray or cut tape), your quantity and any date-code or lot requirements. We reconfirm manufacturer, suffix, package, date code and traceability against the actual offered lot before any commercial quote is issued, and every RFQ gets a reply within 24 hours.

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.

Every suffix in a manufacturer ordering code identifies one exact orderable device — package, temperature grade, packing format or a revision. NCV2903DR2G names the SOIC-8 configuration; a code that differs by even one suffix character may be a different device. Always quote the complete code exactly as it appears on your BOM.
The package (SOIC-8) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.
Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.
Add NCV2903DR2G to your RFQ with the complete ordering code, the manufacturer (onsemi), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
