Substitute Part Grouping Explanation

Substitution of the FS32K148HNT0VLUT is determined by strict equivalence across the following critical parameters:

• Manufacturer and Series: Both parts must originate from NXP USA Inc. within the S32K microcontroller series
• Core Architecture: ARM Cortex-M4F 32-bit single-core processor at 80MHz
• Memory Configuration: 2MB FLASH, 256K RAM, and 4K EEPROM
• I/O Count: 156 I/O pins
• Electrical Specifications: 2.7V to 5.5V supply voltage range and -40°C to 105°C operating temperature
• Package Specification: 176-LQFP (24x24) surface mount package
• Compliance: ROHS3 compliant and REACH unaffected status

The FS32K148HRT0VLUT meets all these criteria and is classified as a parametric equivalent substitute.

Frequently Asked Questions (FAQ)

Q: Can FS32K148HRT0VLUT be used as a direct replacement for FS32K148HNT0VLUT?

A: Yes. Both parts share identical core processor architecture, memory configuration, I/O count, electrical specifications, operating temperature range, and 176-LQFP (24x24) package. They are parametric equivalents within the S32K series.

Q: Are there any differences in connectivity or peripheral support?

A: No. Both parts provide identical connectivity options (CANbus, Ethernet, FlexIO, I2C, LINbus, SPI, UART/USART) and peripheral support (I2S, POR, PWM, WDT).

Q: What determines substitution eligibility for S32K microcontrollers?

A: Substitution is valid when the following parameters match: manufacturer, series, core processor type, clock speed, memory sizes (FLASH, RAM, EEPROM), I/O count, voltage supply range, operating temperature range, package type, and compliance certifications.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both parts operate across the -40°C to 105°C temperature range, supporting industrial deployment requirements.

Q: What is the significance of the part number suffix difference (HNT0 vs HRT0)?

A: The suffix variation indicates different manufacturing batches or revisions within the same product specification. Both suffixes represent valid S32K148 variants with equivalent electrical and mechanical characteristics.
