Engineering Selection Recommendations

Both the FS32K116LIT0VLFR and FS32K116LIT0VLFT are suitable for direct substitution in applications requiring ARM Cortex-M0+ microcontroller functionality within the S32K product line. Selection between these parts should be based on inventory availability and procurement lead times, as no technical differentiation exists.

Both devices maintain active product status from NXP USA Inc., ensuring continued support and availability. Both are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for industrial and commercial applications. The identical MSL 3 rating (168 hours) applies to both parts, requiring equivalent moisture control during storage and handling.

For applications requiring long-term supply assurance, either part number is acceptable. Verify part number requirements in your bill of materials and procurement documentation to ensure correct component selection for your specific application.

Frequently Asked Questions (FAQ)

Q: Can FS32K116LIT0VLFT be used as a direct replacement for FS32K116LIT0VLFR?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, memory configuration, I/O count, package type, and operating characteristics. No design modifications are required for substitution.

Q: Are there any differences in the 48-LQFP package between these parts?

A: No. Both parts use the identical 48-LQFP (7x7) surface mount package with matching pin assignments, mechanical dimensions, and thermal characteristics.

Q: Do both parts support the same connectivity interfaces?

A: Yes. Both FS32K116LIT0VLFR and FS32K116LIT0VLFT include identical connectivity options: CANbus, FlexIO, I2C, LINbus, SPI, and UART/USART.

Q: What is the significance of the different part number suffixes?

A: The part numbers differ only in their suffix designation (VLFR vs. VLFT). Both designations refer to the same S32K116 microcontroller with identical core specifications, memory, and peripheral configuration. The suffix variation does not indicate functional or electrical differences.
