INA219BIDCNR

Texas Instruments

INA219BIDCNR is a Texas Instruments B-grade zero-drift bidirectional current/power monitor in SOT-23-8, 3000-piece large reel — 0.5% maximum accuracy over temperature (B grade), 0–26 V bus sensing, 3–5.5 V supply, 12-bit ADC with programmable averaging to 128 samples, calibration register for direct ampere and watt readouts, 16 programmable I2C addresses, −40 °C to +125 °C. The B grade is the selection point: 0.5% maximum accuracy versus 1% on the A grade — for power-rail monitoring and battery gauging where the error budget is tight, the B grade earns its premium. Selection advice: the DCN code is SOT-23-8 — INA219BIDR is the same B-grade die in SOIC-8, not footprint-compatible. The R suffix is the 3000-piece reel; INA219BIDCNT is the identical part on 250-piece reel for prototypes. Size the shunt for your current range and write the calibration register once — current and power then read out directly. Evidence: TI INA219 datasheet (Rev. G) confirms B-grade 0.5%, SOT-23-8, 0–26 V and the 3000-reel option. Match the full INA219BIDCNR code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SELECTION GUIDANCE

INA219BIDCNR selection guidance

INA219BIDCNR is a INA219 from Texas Instruments, orderable in the SOT-23-8 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.

Within the same series, also consider: INA219AIDCNR · INA219AIDCNT — packing SMALL T&R; Same SOT-23-8 package as INA219AIDCNR; this difference alone does not require PCB pad changes; factory packing is SMALL T&R, 250 per pack; INA219AIDCNR is LARGE T&R, 3,000 per pack. · INA219AIDR — package SOIC-8; packing LARGE T&R; Package/pins: SOIC (D), 8 pins; INA219AIDCNR is SOT-23 (DCN), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is LARGE T&R, 2,500 per pack; INA219AIDCNR is LARGE T&R, 3,000 per pack. · INA219BIDCNT — packing SMALL T&R; Grade B accuracy differs from the on-site Grade A: per the manufacturer datasheet at PGA=/1, max input offset is ±50 µV, Grade A is ±100 µV; calibration should be reviewed; same SOT-23-8 package as INA219AIDCNR; this difference alone does not require PCB pad changes; factory packing is SMALL T&R, 250 per pack; INA219AIDCNR is LARGE T&R, 3,000 per pack.. These variants share the core design; pick the code whose package and packing match your assembly process and reel requirements. If your BOM lists one of these instead of INA219BIDCNR, do not substitute without checking the exact ordering code — even one suffix character can change the device you receive.

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.

COMMON QUESTIONS

INA219BIDCNR FAQ

What is the difference between INA219BIDCNR and INA219AIDCNR, INA219AIDCNT, INA219AIDR?

These are order-code variants of the same Texas Instruments series. They share the core design; the ordering code selects the exact configuration — INA219AIDCNR (SOT-23-8); INA219AIDCNT: Same SOT-23-8 package as INA219AIDCNR; this difference alone does not require PCB pad changes; factory packing is SMALL T&R, 250 per pack; INA219AIDCNR is LARGE T&R, 3,000 per pack.; INA219AIDR: Package/pins: SOIC (D), 8 pins; INA219AIDCNR is SOT-23 (DCN), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is LARGE T&R, 2,500 per pack; INA219AIDCNR is LARGE T&R, 3,000 per pack.. INA219BIDCNR itself is the SOT-23-8 configuration. A code that differs by even one character may be a different device, so always quote the complete code exactly as it appears on your BOM.

What is the difference between package and packing for INA219BIDCNR?

The package (SOT-23-8) 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.

Can you provide traceability documents for INA219BIDCNR?

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.

How do I request a quotation for INA219BIDCNR?

Add INA219BIDCNR to your RFQ with the complete ordering code, the manufacturer (Texas Instruments), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
