Substitute Part Grouping Explanation

Substitution eligibility for the FS32K142HFT0MLHT is determined by strict equivalence across the following critical parameters:

Core Architecture: ARM® Cortex®-M4F 32-bit single-core processor
Clock Speed: 80MHz operation
Memory Configuration: 256KB FLASH, 32KB RAM, 4KB EEPROM
Voltage Range: 2.7V ~ 5.5V supply compatibility
I/O Count: 58 I/O pins
Package Form Factor: 64-LQFP (10x10) surface mount
Connectivity Interfaces: CANbus, FlexIO, I2C, LINbus, SPI, UART/USART
Compliance Standards: ROHS3 Compliant, REACH Unaffected

The FS32K142HAT0MLHT qualifies as a parametric equivalent substitute. The only difference between the main part and substitute is the packaging configuration (Tray versus standard packaging), which does not affect electrical performance, memory specifications, or functional capability.

Both parts satisfy ROHS3 compliance and REACH regulatory requirements. The identical core architecture, 80MHz clock speed, 256KB FLASH memory, and 64-LQFP package form factor ensure direct functional interchangeability in circuit design and PCB layout applications.

Frequently Asked Questions (FAQ)

Q: Can FS32K142HAT0MLHT be used as a direct replacement for FS32K142HFT0MLHT?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, memory configurations, processor architecture, and 64-LQFP package dimensions. The only difference is packaging configuration (Tray versus standard), which does not affect circuit performance or functionality.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: ARM® Cortex®-M4F core processor, 32-bit single-core architecture, 80MHz clock speed, 256KB FLASH memory, 32KB RAM, 4KB EEPROM, 2.7V ~ 5.5V supply voltage, 58 I/O pins, 64-LQFP (10x10) package form factor, and identical connectivity interfaces (CANbus, FlexIO, I2C, LINbus, SPI, UART/USART).

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 3, 168 Hours) ratings. Regulatory and environmental compliance is equivalent.

Q: Does packaging configuration affect PCB design or soldering requirements?

A: No. Both parts use identical 64-LQFP (10x10) surface mount package dimensions and pin configurations. PCB layout, footprint design, and soldering parameters remain unchanged regardless of packaging configuration selection.

Q: What inventory considerations should guide part selection?

A: FS32K142HFT0MLHT has 46,591 units in stock, while FS32K142HAT0MLHT has 7,169 units available. Selection should align with supply chain lead time requirements and volume procurement strategies.
