Substitute Part Grouping Explanation

Substitution eligibility for the R5F2L368CDFP#30 is determined by the following critical parameters:

Core processor architecture (R8C)
Core size (16-Bit)
Operating frequency (20MHz)
Program memory capacity (64KB FLASH)
EEPROM and RAM sizes (4K x 8 and 8K x 8 respectively)
Supply voltage range (1.8V ~ 5.5V)
I/O count (52 pins)
Peripheral feature set (LCD, PWM, communication interfaces)
Data converter specifications (A/D 10x10b; D/A 2x8b)
Operating temperature range (-40°C ~ 85°C)

Substitute parts maintain identical functional and electrical specifications. Variations in package configuration (LFQFP vs. LQFP) and physical dimensions (10x10 vs. 14x14) are permitted when PCB layout accommodates the alternative package footprint.

Engineering Selection Recommendations

All substitute parts maintain full functional and electrical equivalence to the R5F2L368CDFP#30. Selection among available substitutes is based on product status and package compatibility:

R5F2L368CDFP#31 is classified as active and maintains identical package configuration (64-LFQFP 10x10) to the original part, requiring no PCB layout modifications.

R5F2L368CDFA#30 and R5F2L368CDFA#31 are classified as active and employ an alternative package configuration (64-LQFP 14x14). These parts require PCB footprint redesign and are suitable for new designs or redesign cycles where package transition is feasible.

All substitute parts comply with ROHS3 and maintain identical moisture sensitivity levels (MSL 3, 168 Hours), ensuring compatibility with existing supply chain and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can R5F2L368CDFP#31 be used as a direct replacement for R5F2L368CDFP#30?

A: Yes. R5F2L368CDFP#31 maintains identical electrical specifications, core architecture, memory configuration, and package footprint (64-LFQFP 10x10). No PCB modifications are required.

Q: What is the difference between LFQFP and LQFP package variants?

A: LFQFP (10x10) and LQFP (14x14) are distinct package configurations with different physical dimensions and pin pitch. LFQFP represents a smaller footprint. Substitution between these packages requires PCB redesign to accommodate the alternative footprint.

Q: Are the R5F2L368CDFA variants suitable for existing designs?

A: R5F2L368CDFA#30 and R5F2L368CDFA#31 are functionally equivalent but employ a larger package footprint (64-LQFP 14x14). These parts are suitable for new designs or redesign cycles where package transition is planned. Existing PCB designs using 64-LFQFP (10x10) footprints require layout modification.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is MSL 3 (168 Hours) across all variants.

Q: Why is the original R5F2L368CDFP#30 classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Renesas Electronics. Active substitute parts from the same series provide continued design support and component availability.
