Giri\u015f<\/h2>\n<\/div>\n
\n
STM32F103RET6 is ST classic Cortex-M3 high-density MCU, 72MHz, 512KB Flash, LQFP-64 package, integrated CAN, USB, 12-bit ADC and multi-channel timer, occupying mainstream consumer, industrial and IoT control market share. Affected by 8-inch wafer capacity competition in 2026, STM32F1 series lead time stretches to 10~16 weeks, spot prices fluctuate frequently. LXBCHIP holds tens of thousands of original STM32F103RET6 spot inventory, meanwhile providing full set pin-compatible ST cross models and domestic low-cost replacement MCUs to help customers cut procurement cost.<\/div>\n<\/div>\n
\n

1. Market Supply & LXBCHIP Inventory Update<\/h2>\n<\/div>\n
\n
    \n
  • Factory supply: ST shifts production capacity to automotive power devices, F1 mainstream MCU allocation decreased; overseas distributors hoard stock pushing spot price up 20%~40% month-on-month<\/li>\n
  • Channel chaos: Small vendors supply reeled bulk stock with unstable date codes, risk of short service life for mass production<\/li>\n
  • Our stock: Over 35,000pcs original STM32F103RET6 in stock, tray & tape packing available, mixed BOM matching support with ST power MOSFET and LDO chips<\/li>\n<\/ul>\n<\/div>\n
    \n

    2. Current Tiered Purchase Price (USD, brand new original)<\/h2>\n<\/div>\n
    \n
      \n
    • 1\u201399 pcs: $3.38 \/ pc<\/li>\n
    • 100\u2013499 pcs: $2.92 \/ pc<\/li>\n
    • 500\u20134999 pcs: $2.45 \/ pc<\/li>\n
    • \u22655000 pcs: Large order preferential price negotiation<\/li>\n<\/ul>\n<\/div>\n
      \n

      3. Two Types of Replacement Solutions<\/h2>\n<\/div>\n
      \n

      1. ST Pin-to-Pin Cross Model (PCB zero modification, software directly compatible)<\/h3>\n<\/div>\n
      \n
        \n
      1. STM32F103VET6: LQFP144 more I\/O resources, upgrade option for expanded peripheral design<\/li>\n
      2. STM32F103ZET6: LQFP144 768KB Flash, for large storage IoT gateway equipment<\/li>\n<\/ol>\n<\/div>\n
        \n

        2. Domestic Low-Cost Pin-Compatible Alternative (PCB unchanged, minor software adaptation, cost cut 30%~50%)<\/h3>\n<\/div>\n
        \n
          \n
        1. GD32F103RET6: Gigadevice mainstream substitute, full register compatible, mature mass production<\/li>\n
        2. HC32F103RET6: Huada 32-bit MCU, industrial temperature range, stable supply with short lead time<\/li>\n<\/ol>\n<\/div>\n
          \n

          4. Typical Application Scenarios<\/h2>\n<\/div>\n
          \n
          Smart home control panels, industrial data acquisition modules, portable medical testing equipment, consumer battery management systems, small IoT gateway terminals<\/div>\n<\/div>\n
          \n

          Sonu\u00e7<\/h2>\n<\/div>\n
          \n
          \n

          STM32F103 series supply pressure will continue in the second half of 2026. Customers can choose original ST spot stock or domestic low-cost pin-compatible alternatives according to project cost budget. LXBCHIP can provide free sample testing of replacement models and full BOM quotation matching service.<\/p>\n
