|---|---|---|---|
| FFF Compatibility | The pinout is completely reassigned/rearranged and the device orientation is rotated 180 degrees in tape packaging.Both parts use the standard 16-TSSOP (0.173 in, 4.40mm width) package style with identical lead pitches.Performs the identical function of bridging UART ASCII commands to an I2C master bus, with some minor register and configuration updates. | Uses a QFN-24 (4x4mm) package instead of a 16-TSSOP package, with a completely different footprint.Physically smaller QFN package with different mounting characteristics and a different physical footprint.Bridges USB (instead of UART) to an I2C/SMBus master interface, requiring a host interface redesign. | |
 AI Summary | SC18IM700IPW by NXP: I2C Controller UART Interface 16-TSSOP. | The SC18IM704PWJ is NXP's official direct functional replacement for the obsolete SC18IM700IPW. While it shares the same 16-TSSOP package, its pinout is entirely redesigned, requiring a PCB layout revision. It offers improved electrical characteristics, including lower power consumption and support for lower system voltages.
| For systems that can shift from a UART host to a USB host, the CP2112-F02-GM provides a robust USB-to-I2C bridging alternative. It operates as an I2C/SMBus master controller and includes GPIO pins, though it utilizes a USB 2.0 interface and comes in a compact QFN-24 package.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The NXP SC18IM700IPW is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the NXP SC18IM700IPW are the SC18IM704PWJ (NXP USA Inc.) and the CP2112-F02-GM (Silicon Labs). Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the SC18IM700IPW are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The SC18IM700IPW (NXP) is a part in the Interface category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
