Substitute Part Grouping Explanation

Substitution for the DF38602RFT4V is determined by the following critical parameters: program memory capacity (16KB FLASH), core bit width (16-bit minimum), supply voltage compatibility (1.8V minimum), surface mount packaging, and RoHS3 compliance. The substitute parts identified meet these core electrical and mechanical requirements while maintaining functional equivalence for embedded microcontroller applications.

The two substitute parts are grouped as follows:

R5F21324DDSP#U0 (Renesas Electronics Corporation): Maintains the same manufacturer ecosystem with 16KB FLASH, 16-bit core, and RoHS3 compliance. Offers enhanced speed (20MHz) and expanded I/O (15 pins) with broader supply voltage range (1.8V ~ 5.5V). Package differs to 20-LSSOP.

LPC802M001JHI33E (NXP USA Inc.): Provides 16KB FLASH with upgraded core architecture (32-bit ARM Cortex-M0+), higher speed (15MHz), and extended operating temperature range (-40°C ~ 105°C). Maintains RoHS3 compliance and similar package footprint (32-HVQFN 5x5). Supply voltage range is 1.71V ~ 3.6V.

Engineering Selection Recommendations

Both substitute parts are classified as active products with current manufacturing support, addressing the obsolescence status of the DF38602RFT4V. All three parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for embedded microcontroller applications.

R5F21324DDSP#U0 is recommended for designs requiring continuity within the Renesas H8/R8C ecosystem. This part maintains 16-bit architecture compatibility while providing performance improvements and extended supply voltage tolerance. The 20-LSSOP package requires PCB layout modification compared to the original 32-VQFN footprint.

LPC802M001JHI33E is recommended for applications where enhanced processing capability and extended temperature range are beneficial. The 32-bit ARM Cortex-M0+ architecture provides architectural advantages over the legacy H8/300H core. The 32-HVQFN package maintains similar pin count and footprint dimensions to the original part, facilitating easier PCB migration.

Frequently Asked Questions (FAQ)

Q: Can the R5F21324DDSP#U0 directly replace the DF38602RFT4V on the same PCB?

A: No. The R5F21324DDSP#U0 uses a 20-LSSOP package versus the original 32-VQFN (5x6) package. PCB layout redesign is required. Pin count reduction from 32 to 20 necessitates functional remapping and firmware adaptation.

Q: Is the LPC802M001JHI33E pin-compatible with the DF38602RFT4V?

A: The LPC802M001JHI33E uses a 32-HVQFN (5x5) package compared to the original 32-VQFN (5x6). While both are 32-pin QFN packages, the footprint dimensions differ slightly (5x5mm versus 5x6mm). Pin assignments are not identical and require firmware porting.

Q: What are the key electrical differences between these substitutes?

A: The R5F21324DDSP#U0 supports higher supply voltage (up to 5.5V) and operates at 20MHz. The LPC802M001JHI33E operates at 15MHz with a 32-bit core and supports extended temperature range (-40°C to 105°C). Both maintain the 16KB FLASH memory specification of the original part.

Q: Are all three parts RoHS compliant?

A: Yes. The DF38602RFT4V, R5F21324DDSP#U0, and LPC802M001JHI33E are all ROHS3 compliant with MSL 3 (168 Hours) moisture sensitivity rating.

Q: Which substitute is better for low-power applications?

A: The DF38602RFT4V operates at 4MHz with supply voltage starting at 1.8V. The LPC802M001JHI33E also begins at 1.71V and includes brown-out detect functionality. The R5F21324DDSP#U0 operates at 20MHz, consuming more power at equivalent supply voltages. Selection depends on specific power budget requirements.

Q: Do these parts share the same connectivity interfaces?

A: All three parts include I2C and PWM functionality. The DF38602RFT4V includes IrDA and SCI. The R5F21324DDSP#U0 includes LINbus and UART/USART. The LPC802M001JHI33E includes SPI and UART/USART. Interface compatibility must be verified against application requirements.
