Engineering Selection Recommendations

All three substitute parts—R5F2L368CDFA#30, R5F2L368CDFA#31, and R5F2L368CDFP#31—are parametrically equivalent to the R5F2L368CDFP#V2 and maintain full electrical and functional compatibility.

R5F2L368CDFP#31 is the primary substitute for direct replacement. It maintains the identical 64-LFQFP (10x10) package form factor as the original part, eliminating PCB layout modifications. This part is currently active in production.

R5F2L368CDFA#30 and R5F2L368CDFA#31 are functionally equivalent alternatives with identical electrical specifications. Both use the 64-LQFP (14x14) package form factor, which differs from the original. Selection of these parts requires PCB redesign to accommodate the larger package footprint.

All substitute parts carry ROHS3 compliance, REACH Unaffected status, and EAR99 export classification, matching the regulatory profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can R5F2L368CDFA#30 and R5F2L368CDFA#31 be used as direct drop-in replacements for R5F2L368CDFP#V2?

A: No. While electrically and functionally equivalent, these parts use a 64-LQFP (14x14) package versus the original 64-LFQFP (10x10) package. PCB layout modification is required to accommodate the larger footprint.

Q: Is R5F2L368CDFP#31 a direct replacement for R5F2L368CDFP#V2?

A: Yes. R5F2L368CDFP#31 maintains the identical 64-LFQFP (10x10) package form factor and all electrical specifications. No PCB modifications are necessary.

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

A: LFQFP (Low-profile Fine-pitch Quad Flat Package) uses a 10x10mm footprint with 0.5mm pin pitch. LQFP (Low-profile Quad Flat Package) uses a 14x14mm footprint with 0.5mm pin pitch. The LQFP variant provides a larger package body.

Q: Are all substitute parts currently in production?

A: Yes. R5F2L368CDFA#30, R5F2L368CDFA#31, and R5F2L368CDFP#31 are all active products. The original R5F2L368CDFP#V2 is discontinued.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99, matching the original part's regulatory status.

Q: What is the MSL rating, and does it differ across parts?

A: All parts carry MSL 3 (168 Hours) rating. This indicates moisture sensitivity level 3 with a floor life of 168 hours after bag opening under controlled conditions.
