Substitute Part Grouping Explanation

Substitute parts for the FS32K142HRT0VLHT are determined by strict equivalence across the following critical parameters:

• Base Product Number: FS32K142 (identical series designation)
• Core Processor Architecture: ARM Cortex-M4F (same instruction set and performance tier)
• Core Size and Speed: 32-Bit Single-Core at 80MHz (identical processing capability)
• Memory Configuration: 256KB FLASH, 32KB RAM, 4KB EEPROM (identical memory footprint)
• Voltage Supply Range: 2.7V ~ 5.5V (identical power requirements)
• Package Type: 64-LQFP (10x10) (identical physical form factor and pin count)
• Operating Temperature Range: -40°C ~ 105°C (identical thermal specifications)
• Connectivity and Peripherals: CANbus, FlexIO, I2C, LINbus, SPI, UART/USART, POR, PWM, WDT (identical interface capabilities)
• Compliance: ROHS3 Compliant, MSL 3 (identical environmental and handling requirements)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the FS32K142HRT0VLHT and FS32K142HFT0VLHT are active production devices from NXP USA Inc. with identical electrical, mechanical, and compliance specifications. Selection between these parts is based on:

• Supply Availability: Choose the part with confirmed inventory and lead time alignment with project schedules.
• Compliance Requirements: Both parts meet ROHS3 compliance and REACH unaffected status, suitable for regulated applications.
• Moisture Handling: Both parts carry MSL 3 rating (168 Hours), requiring identical storage and handling protocols.
• Packaging Format: Both parts are supplied in Tray packaging with identical 64-LQFP (10x10) form factor, ensuring PCB layout compatibility without redesign.

No technical performance differentiation exists between these parts. Selection is a procurement decision based on availability and supply chain factors.

Frequently Asked Questions (FAQ)

Q: Can FS32K142HFT0VLHT be used as a direct replacement for FS32K142HRT0VLHT?

A: Yes. Both parts are parametric equivalents with identical core processor, memory configuration, voltage supply range, package type, operating temperature range, and peripheral set. No circuit modifications or firmware changes are required for substitution.

Q: Are there any differences in pin configuration between these parts?

A: No. Both parts use the 64-LQFP (10x10) package with 58 I/O pins. Pin assignments, connectivity interfaces (CANbus, FlexIO, I2C, LINbus, SPI, UART/USART), and peripheral mapping are identical.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by matching: base product number (FS32K142), core processor (ARM Cortex-M4F), core size (32-Bit Single-Core), speed (80MHz), memory sizes (256KB FLASH, 32KB RAM, 4KB EEPROM), voltage supply range (2.7V ~ 5.5V), package type (64-LQFP 10x10), operating temperature range (-40°C ~ 105°C), and peripheral set (CANbus, FlexIO, I2C, LINbus, SPI, UART/USART, POR, PWM, WDT).

Q: Do these parts require different PCB layouts?

A: No. Both parts share identical package specifications (64-LQFP 10x10), pin count (58 I/O), and pin assignments. Existing PCB layouts require no modification for part substitution.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry MSL 3 rating with 168-hour floor life. Storage conditions, handling procedures, and reflow soldering parameters must comply with IPC-A-610 standards for MSL 3 components.

Q: Are both parts suitable for automotive applications?

A: Both parts are active production devices from NXP USA Inc. with ROHS3 compliance and REACH unaffected status. Suitability for specific automotive applications depends on system-level requirements and qualification processes, which are outside the scope of component-level equivalence.
