FFF CompatibilityPinout is nearly identical except for Pin 84, which is OWE (Oscillator Watchdog Enable) on the Infineon part, whereas it is RPD (Return from Powerdown) on the STMicroelectronics part.Both devices share the same 144-pin plastic quad flat package (PQFP-144 / MQFP-144) footprint with a 28x28 mm body.Both are 16-bit ROMless microcontrollers running at 25 MHz with 4KB of internal RAM, 111 I/Os, and a 16-channel 10-bit ADC.Identical pin layout and package footprint since it is a direct sibling within the same product series.Uses the exact same 144-PQFP (28x28 mm) package.Operates over a narrower temperature range (-40°C to +85°C) compared to the original part's automotive range (-40°C to +125°C).
AI Summary

ST10R167-Q3 by STMicroelectronics: ST10 ST10 Microcontroller IC 16-Bit 25MHz ROMless 144-PQFP (28x28).

The SAK-C167CR-LM HA+ is the closest second-source equivalent to the obsolete ST10R167-Q3, offering matching performance, memory size, and temperature range. It is based on the same licensed C166 core architecture. However, it is also obsolete, meaning it is best suited for maintaining legacy production or repair rather than new designs.

  • Matches the full -40°C to +125°C automotive temperature range of the original part
  • Identical core architecture (C166/C167) and peripheral set including CAN 2.0B
  • Same 144-pin MQFP physical package shape and dimensions (28x28 mm)
  • The part is obsolete and has limited current availability
  • Minor schematic check is required to ensure Pin 84 (OWE vs RPD) does not conflict with your circuit design

The ST10R167-Q6 is a direct sibling from the same manufacturer series, offering absolute pin-to-pin and software compatibility. It is rated for industrial temperatures up to +85°C instead of the automotive +125°C. Like the queried part, this component is obsolete and only available from legacy stocks.

  • True drop-in pin-to-pin compatibility with identical pin definitions including Pin 84 (RPD)
  • Shares the exact same silicon design and instruction set from the same ST10 family
  • Reduced maximum operating temperature limit (+85°C vs +125°C)
  • The part is obsolete and shares the same lifecycle supply risks

  • Stay compliant and production-ready

You searched one part. Parter watches your whole BOM.

  1. 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.

  2. 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.

  3. 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 STMicroelectronics ST10R167-Q3 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.
