The XL1403 is attributed to Xinluda (Xinluda Information Technology Co., Ltd.) as a Darlington transistor array driver, belonging to the company’s family of multi-channel load-driver ICs. Xinluda’s Darlington array catalog includes verified parts such as the 7-channel XL1413, XL2003 and XL2004 in SOP-16/DIP-16 packages, and 8-channel devices in the XL28xx series. These devices integrate NPN Darlington pairs to provide a simple, low-component-count way to interface low-power logic outputs to higher-voltage, higher-current loads such as relays, motors, lamps, displays and solenoids.
Important sourcing note: The exact part number “XL1403” could not be confirmed against Xinluda’s published Darlington transistor listing or major distributors (LCSC, JLCPCB) at the time of writing. The closest verified Xinluda device is the 7-channel XL1413. Please confirm the exact marking, package and electrical ratings with our sourcing team before designing in.
Note: Pacific Component Xchange publishes only specifications that can be confirmed. Per-channel electrical ratings (output voltage, output current and input thresholds) for the exact XL1403 device are not publicly documented and must be confirmed against the Xinluda datasheet for your specific marking and date/lot code before designing in. Contact us and we will provide the controlled datasheet with your quotation.
The XL1403 is a hard-to-find part with little to no authorized-distributor stock in Western markets and limited public documentation, making it a part best secured through a specialist independent distributor. Pacific Component Xchange is an independent distributor focused on hard-to-find and obsolete power-management ICs, drivers and optocouplers. We help engineers and buyers source allocated, end-of-life and Asian-market-only parts with authenticity screening, supply-chain traceability and global shipping.
Request a quote (RFQ) for the XL1403 today and our sourcing team will confirm the exact part marking, availability, lead time, date/lot codes and pricing for your required quantity. Whether you need a handful of units for a repair build or production volumes, we can help you lock in supply of this and related Xinluda Darlington array drivers such as the XL1413.
The XL1403 is attributed to Xinluda as a Darlington transistor array driver used to switch relays, lamps, motors and other loads from low-power logic signals. Note that this exact part number is not currently confirmed in Xinluda's published catalog; the closest verified device is the 7-channel XL1413 in a SOP-16 package.
It is attributed to Xinluda (Xinluda Information Technology Co., Ltd.), a Chinese IC supplier whose product lines include logic, interface, RS-485 transceivers, DC-DC converters and Darlington transistor array drivers.
Public documentation for the exact XL1403 marking could not be confirmed. Xinluda's comparable 7-channel Darlington arrays, such as the XL1413, are supplied in SOP-16 surface-mount packages, so SOP-16 is the most likely package. Confirm with our sourcing team before ordering.
It is a load driver. Typical applications for this class of Darlington array include relay and solenoid drivers, stepper and DC motor drive stages, lamp and display drivers, and general industrial and home-appliance control I/O.
A dedicated public datasheet for the XL1403 marking was not located. Xinluda publishes its Darlington array documentation on its official site. Pacific Component Xchange will work to supply the controlled datasheet matching your exact marking and date/lot code along with your quotation. Contact us to confirm output voltage, output current and input specifications.
The XL1403 is a hard-to-find, request-for-quote part with limited and unverified distributor availability. Pacific Component Xchange sources parts like this through specialist channels. Submit an RFQ and our team will confirm the exact part, availability, lead time and pricing for your quantity.
