Thank you very much for your reply. I would like to first evaluate the characteristics of this component. If the sample testing is successful, I will reach out to your distributor. Alternatively, could you recommend a suitable distributor?

Hi,

I can confirm that the FXTH8709116T1, along with the entire FXTH87 TPMS family, has been discontinued. The recommended replacement family for new designs is the NTM88.

To match your current device (100–900 kPa pressure range, XZ dual-axis accelerometer), the corresponding NTM88 variant with the 930 kPa range and XZ-axis option is indeed the NTM88H series.

To support the transition, there is available a dedicated migration application note: AN12524 – Migration from FXTH87/87E to NTM88. This AN is a helpful resource for adapting your existing FXTH87/87E design to the NTM88 family.

One important note: as of February 2, 2026, our MEMS sensor products (including the TPMS portfolio) have been transitioned to STMicroelectronics. For product availability, samples, and further design support, please contact STMicroelectronics directly.

BRs, Tomas

Hello,

FXTH8709116T1 belongs to NXP’s FXTH87 family of Tire Pressure Monitoring Sensors (TPMS). This entire family has been officially discontinued (No Longer Manufactured).

Official Recommended Replacement

NXP officially recommends migrating to the NTM88 family for all new designs.

• Official statement: “NTM88 is the recommended family for new designs as the FXTH87 family is discontinued.”
• Migration guide: AN12524 – Migration from FXTH87/87E to NTM88

Key Specification Comparison & Recommendation

Item FXTH8709116T1 (Original) Recommended NTM88 Direction Notes

Pressure Range	Approx. 100–900 kPa	NTM88H series (90–930 kPa)	Closest match
Accelerometer	Dual-axis (X + Z)	Dual-axis (XZ) supported	Matching options available
Package	7 × 7 mm QFN	4 × 4 mm QFN	Not pin-compatible – board redesign required
MCU + RF	Integrated 8-bit MCU + RF	Integrated 8-bit MCU + RF	Functionally equivalent
Status	Discontinued	Active (use “S” suffix versions)	-

Recommended starting points (final selection depends on your exact requirements):

• NTM88H125S or similar dual-axis variants in the 90–930 kPa range
• Alternative: NTM88J series (higher pressure range, e.g. 90–1110 kPa)

Important Notes

1. Not a drop-in / pin-to-pin replacement The package size has changed from 7×7 mm to 4×4 mm, so a PCB redesign is mandatory.
2. Firmware / software migration required Please refer to NXP’s application note AN12524 for detailed migration guidance. Firmware and library functions differ.
3. Short-term production advice
   • If you still need the original part for ongoing production, check remaining stock of FXTH8709116T1 through distributors or the gray market as soon as possible.
   • For long-term production, you must transition to the NTM88 family.
   • You can contact them via wechat:+85259975614. They are selling off their remaining inventory in bulk, along with COC certificates.
