Key Parameters

Substitute Part Grouping Explanation

Substitution for the ATSAMA5D42A-CUR is determined by strict equivalence in the following key parameters: core processor, architecture (number of cores and bus width), clock speed, co-processors/DSP, RAM controller support, graphics and display features, Ethernet and USB interface count, voltage I/O levels, operating temperature range, security features, mounting type, package, and additional interfaces. Compliance with RoHS, MSL rating, and REACH status are mandatory to ensure regulatory and supply chain compatibility. Only parts matching all listed parameters are considered substitutes.

Parameter Comparison

Engineering Selection Recommendations

The ATSAMA5D42A-CUR is obsolete. The ATSAMA5D42B-CUR is listed as active and meets all specified electrical, mechanical, and compliance parameters, including RoHS3 compliance, MSL 3 (168 hours), and REACH unaffected status. Both parts use the same package and interface types. Selection can be made based on product status and compliance equivalence.

Frequently Asked Questions (FAQ)

Q1: What key criteria determine suitable substitutes for the ATSAMA5D42A-CUR?
A1: Substitution is based on match of core processor, number of cores/bus width, speed, RAM controllers, co-processors, security features, operating temperature, voltage I/O range, interface types, package/case, mounting type, and compliance certifications (RoHS, REACH, MSL).

Q2: Are ATSAMA5D42B-CUR and ATSAMA5D42A-CUR mechanically and electrically compatible?
A2: Both parts use the same 361-TFBGA (16x16) package, have identical voltage I/O, and matching functional parameters and interface capabilities.

Q3: Is compliance maintained when switching to the substitute part?
A3: Both the original and substitute parts are ROHS3 compliant, REACH unaffected, and share the same MSL.

Q4: What should be checked for package-level compatibility when substituting?
A4: Confirm identical package/case (361-TFBGA), dimensions (16x16mm), and mounting type (surface mount) for direct replacement.

Q5: How does product status affect substitution?
A5: The original part is obsolete, while the substitute is active, ensuring ongoing availability within the same compliance and technical criteria.
