Engineering Selection Recommendations

Both R5F2136CSNFA#30 and R5F2136CSNFA#50 are Active product status alternatives to the Obsolete R5F2136CSNFP#V0. All three parts maintain identical electrical and functional specifications, ensuring direct functional compatibility.

The primary design consideration is package footprint. The main part uses a 64-LFQFP (10x10) package, while both substitutes use a 64-LQFP (14x14) package. PCB layout modifications are required to accommodate the larger package dimensions.

Both substitute parts carry ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements equivalent to the main part. The Moisture Sensitivity Level differs between the main part (MSL 1, Unlimited) and substitutes (MSL 3, 168 Hours), requiring appropriate handling and storage protocols during manufacturing.

Frequently Asked Questions (FAQ)

Q: Are R5F2136CSNFA#30 and R5F2136CSNFA#50 electrically identical to R5F2136CSNFP#V0?

A: Yes. All three parts share identical core processor architecture, memory configuration, speed, voltage range, I/O count, connectivity options, and peripherals. Electrical functionality is fully equivalent.

Q: What is the primary difference between these parts?

A: The main difference is package dimensions. R5F2136CSNFP#V0 uses a 64-LFQFP (10x10) package, while R5F2136CSNFA#30 and R5F2136CSNFA#50 use a 64-LQFP (14x14) package. This requires PCB footprint redesign.

Q: Why is the main part classified as Obsolete?

A: R5F2136CSNFP#V0 is no longer in active production. R5F2136CSNFA#30 and R5F2136CSNFA#50 are Active alternatives from the same series, ensuring continued design support and component availability.

Q: Do the substitute parts have different Moisture Sensitivity Levels?

A: Yes. R5F2136CSNFP#V0 has MSL 1 (Unlimited shelf life), while R5F2136CSNFA#30 and R5F2136CSNFA#50 have MSL 3 (168 hours). This affects storage and handling requirements during manufacturing.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: Can I use R5F2136CSNFA#30 or R5F2136CSNFA#50 as direct drop-in replacements?

A: Electrical functionality is direct. However, the larger package footprint (14x14 vs. 10x10) requires PCB layout modifications. Pin assignments and electrical connections remain compatible.
