The global electronic component market showed a significant uptick in October, led by rising demand across NXP Automotive Chips, automotive-grade small signal devices, MEMS sensors, digital isolators, and high-speed analog components. Market data indicates that these categories saw a 25%–60% month-over-month increase in search volume and inquiry activity, along with noticeable price hikes and tightening supply.
Below is a summary of the most frequently requested and fastest-rising components this month (for reference only, not trade recommendations):
- High-demand automotive diode BAV99-Q
- Tight-supply automotive MOSFET BUK7K6R2-40E
- High-volume but short-supplied PESD1LIN
- Six-axis IMU ICM-42688-P
- Miniature digital barometric sensor DPS368XTSA1
- High-performance e-compass LSM303AGRTR
- TI high-speed op-amp OPA690IDBVR
- Popular domestic digital isolator CA-IS3722HS
Many of these components are commonly found in NXP automotive platforms, particularly in body control, ADAS sensor modules, power management, and domain controller designs. Therefore, their supply-and-demand fluctuations often reflect broader movements within the automotive electronics supply chain.
BAV99-Q (Automotive High-Speed Switching Diode)
The search volume for BAV99-Q surged by over 300% in October, with prices rising sharply from USD-cent levels to nearly USD 1 in some markets.
This diode is frequently used in NXP Automotive Chips–related circuits, such as high-speed switching, signal conditioning, and reverse-polarity protection.
The shortage stems from strict automotive requirements for reverse recovery time, leakage performance, and high-temperature stability. Channel inventory dropped by more than 90%, pushing related models like BAS316-Q higher as well.
BUK7K6R2-40E (Automotive MOSFET)
Inquiry volume jumped 250% MoM, with market prices lifted from tens of RMB to triple-digit levels in severe cases.
Its ultra-low 5.8 mΩ Rds(on) and 40 V automotive rating make it a core device in NXP automotive powertrain and body control applications, including motor drive, lighting systems, and electromagnetic valve control.
Global lead times for automotive MOSFETs have expanded to 20–26 weeks, tightening supply for the entire BUK series.
PESD1LIN (LIN-Bus ESD/TVS Protection Diode)
Market heat increased 120%–180%, with prices climbing to 0.4–1 RMB.
The device offers ultra-low parasitic capacitance (≤12 pF) and ±30 kV ESD robustness, making it essential for LIN-bus protection in automotive networks.
After the manufacturer listed it as NRND, downstream customers began early stocking, causing inventory to fall by 70%.
PESD protection devices are among the highest-volume categories supporting NXP automotive communication modules, amplifying the shortage.
ICM-42688-P (Six-Axis IMU)
October saw a 40% increase in inquiries, with prices rising from 9 RMB to 13–15 RMB.
Its gyro noise density of 0.005 dps/√Hz makes it ideal for UAV flight control, XR motion tracking, and robotics applications.
With MEMS packaging delays of 1–2 weeks and strong Q4 demand from UAV and XR products, supply remains tight.
ICM-42688-P is often paired with NXP automotive MCUs in sensor-fusion designs.
DPS368XTSA1 (Digital Barometric Pressure Sensor)
Prices remained elevated at 15–20 RMB, nearly twice the normal level.
With ±0.002 hPa precision and a compact 2.0 × 2.5 mm package, it is widely used in smart wearables, UAV altitude measurement, and environmental monitoring systems.
Infineon’s official stock is currently zero, and distributor inventory is down to 20–30%, indicating a long-term shortage.
LSM303AGRTR (E-Compass Module)
Prices rose from 8 RMB to 25–30 RMB, reflecting a strong demand surge from robotics, drone flight control, and smart mobility projects.
The integrated 3-axis accelerometer and 3-axis magnetometer (110 nT/√Hz noise) offer precise orientation and motion detection, making drop-in replacements challenging.
Inventory declined by 60% from September.
OPA690IDBVR (High-Speed Operational Amplifier)
Search activity doubled (+100%), with market prices around 7–8 RMB, lower than TI’s official pricing due to channel inventory draw-down.
With a 400 MHz gain bandwidth, it is widely used in high-speed imaging, ADC front-end buffering, and instrumentation.
TI’s production reallocation toward automotive and industrial lines has reduced available supply.
CA-IS3722HS (Digital Isolator)
Prices reached 1.5 RMB, up nearly 90% from early this year.
Supporting up to 3.75 kVRMS / 5 kVRMS isolation and 150 Mbps data rates, it serves as an effective alternative to several overseas isolator models.
Demand growth in industrial automation and motor control resulted in a 50% YoY inventory decline.
Market Outlook: Shortages Expected to Extend Into Q1 Next Year
Across October, automotive-grade components, MEMS sensors, digital isolators, and high-speed analog ICs continued to show structural shortages driven by limited substitutability, extended lead times, and concentrated demand.
With Q4 traditionally being a peak stocking period, the current tight supply is likely to persist into Q1 of next year.
Companies seeking alternative components, bulk procurement, replacement suggestions, or lead-time verification for any of the above devices can benefit from coordinated checks across local and distributor inventories. Ensuring proactive planning is essential to maintaining stable production and avoiding unexpected supply chain disruptions.
If you need to replenish stock, compare prices, select alternatives, or confirm delivery dates for the above models, 7SEtronic can simultaneously organize real-time inventory, quotations, and feasible alternatives from the channels to help your company maintain initiative and stability amidst supply chain fluctuations.
