Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

The R5F11TLGDFB#15, R5F11TLGDFB#35, R5F10NLGDFB#15, and R5F10NLGDFB#35 are all designated as "Active" products by Renesas Electronics Corporation. These parts maintain full electrical and mechanical equivalence to the R5F11TLGDFB#10 and are recommended for new designs and ongoing production applications. The active status ensures continued manufacturer support, availability, and compliance with current regulatory requirements.

Secondary Substitutes (Not For New Designs):

The R5F11TLGDFB#30 carries the same "Not For New Designs" designation as the R5F11TLGDFB#10. While electrically and mechanically equivalent, this part is suitable only for legacy system maintenance and repair applications where component continuity is required.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with environmental and regulatory requirements. The R5F11TLGDFB#15, R5F11TLGDFB#35, R5F10NLGDFB#15, and R5F10NLGDFB#35 carry EAR99 ECCN classification, while the R5F11TLGDFB#10 and R5F11TLGDFB#30 are classified as 3A991A2. This difference does not affect functional substitution but may impact export documentation requirements.

Packaging Designation:

The suffix designations (#10, #15, #30, #35) indicate different tape reel packaging configurations and do not affect electrical or mechanical compatibility. Selection among these variants is determined by procurement and assembly requirements rather than functional considerations.

Q: Does the packaging suffix affect electrical performance?

A: No. The suffix designations (#10, #15, #30, #35) refer exclusively to tape reel packaging configurations and do not affect electrical characteristics, memory capacity, speed, voltage supply range, or any other functional parameter.

Q: Are all substitute parts available in the same 64-LFQFP package?

A: Yes. All substitute parts are supplied in the 64-LFQFP (10x10) package configuration, ensuring identical PCB footprint and mounting compatibility.

Q: What is the moisture sensitivity level for these microcontrollers?

A: All parts, including the R5F11TLGDFB#10 and all substitute variants, have a Moisture Sensitivity Level (MSL) of 3 with a floor life of 168 hours. This specification applies to all identified substitutes.

Q: Can I mix different suffix variants in the same production run?

A: Yes. All suffix variants (#10, #15, #30, #35) are electrically and mechanically equivalent and can be used interchangeably within the same assembly. However, export compliance documentation may differ based on ECCN classification.
