The -40°C to 105°C operating temperature range suits it for factory-floor automation, outdoor telecom cabinets, and under-hood automotive environments where ambient heat is a factor. It is not rated for military or avionics temperature extremes, but covers the industrial and extended-commercial band well. ## Lifecycle and sourcing reality It is ROHS3 compliant.","metaTitle":"ULN2003AIDR 7-Channel Darlington Driver, 500 mA, 50 V","metaDescription":"TI ULN2003AIDR 7-channel NPN Darlington relay driver, 500 mA per channel, 50 V load, SOIC-16.

Common in PLC outputs, industrial control panels, and appliance logic boards. The built-in flyback diodes simplify driving inductive loads from logic-level signals."},{"question":"What is the difference between ULN2003AIDR and ULN2003?","answer":"The ULN2003AIDR is the surface-mount SOIC-16 version of the same die. The base ULN2003 is typically in a DIP-16 through-hole package. Electrical ratings (500 mA per channel, 50 V load, inverting inputs) are identical. The 'A' suffix indicates the industrial temperature range (-40°C to 105°C) versus the commercial 0°C to 70°C of the standard ULN2003."},{"question":"What is the closest pin-compatible alternative to ULN2003AIDR in this component family?","answer":"The ULN2003AIDR is pin-compatible with all SOIC-16 ULN2003 variants from TI and second-source manufacturers (e.g., STMicroelectronics, NXP). The ULN2004AIDR is the same package and pinout but with higher input impedance for CMOS logic instead of TTL. For through-hole designs, the ULN2003AIN (DIP-16) is the same die."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ULN2003AIDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ULN2003AIDR when reusing this data.
