ULN2803CDWR
Texas InstrumentsULN2803CDWR is a Texas Instruments 8-channel 50 V Darlington transistor array in SOIC-20, tape and reel — for driving relays, solenoids and low-side loads from logic outputs in production. Eight integrated Darlington pairs with freewheeling diodes is the selection point: one chip replaces eight transistor-plus-diode circuits. Selection advice: the CDWR suffix denotes SOIC-20 in tape and reel — the current-production C variant, the correct pick for new designs (the A variant is end of life). 500 mA per channel; watch total package dissipation with multiple channels on. TI lists this part as ACTIVE. Parameters verified against the TI official product page.

ULN2803CDWR FAQ
What should I check before substituting ULN2803CDWR with another 8-channel Darlington transistor array?
Match the full ordering code, not the series name: package (SOIC-20), temperature grade and packing all ride on the suffixes. A same-series code in a different package is a different orderable device, so confirm the substitute against the Texas Instruments datasheet before changing the BOM.
