Engineering Selection Recommendations

All listed substitute parts maintain Active product status with Microchip Technology, ensuring continued availability and support. ATSAML11D15A-MUT is a direct series equivalent to the main part ATSAML11D15A-MUTKPH, differing only in packaging variant (standard Tape & Reel versus the MUTKPH designation). ATSAML10D15A-MUT represents a cross-series substitute from the SAM L10 family, maintaining identical electrical specifications, memory configuration, and peripheral feature set while operating under different ECCN classification (3A991A2 versus 5A992C).

All parts comply with ROHS3 and REACH requirements, with MSL rating of 3 (168 Hours) for moisture sensitivity. Selection between these parts should be based on supply chain availability, packaging requirements, and regulatory classification needs specific to the application or export destination.

Frequently Asked Questions (FAQ)

Q: Can ATSAML10D15A-MUT be used as a direct replacement for ATSAML11D15A-MUTKPH?

A: ATSAML10D15A-MUT is electrically and functionally equivalent to ATSAML11D15A-MUTKPH. Both devices share identical core processor, memory configuration, operating frequency, voltage supply range, I/O count, connectivity interfaces, and peripheral features. The primary difference is series designation (SAM L10 versus SAM L11) and ECCN classification. Substitution is valid from an electrical standpoint; however, regulatory or export compliance requirements may differ based on ECCN classification.

Q: What is the difference between ATSAML11D15A-MUTKPH and ATSAML11D15A-MUT?

A: These parts are from the same SAM L11 series with identical electrical and functional specifications. The difference lies in packaging designation: MUTKPH and MUT represent different packaging variants supplied by Microchip Technology. Both are surface mount 24-VQFN (4x4) configurations in Tape & Reel packaging. Selection between them depends on specific packaging requirements or supplier availability.

Q: Are all substitute parts compatible with the same PCB layout?

A: Yes. All listed substitute parts use the identical 24-VQFN (4x4) package with exposed pad, surface mount configuration. PCB footprint, pin assignment, and thermal pad dimensions are consistent across all parts, allowing direct substitution without layout modification.

Q: Do substitute parts have the same compliance certifications?

A: All substitute parts are ROHS3 Compliant and REACH Unaffected. MSL rating is 3 (168 Hours) for all parts. However, ECCN classifications differ between SAM L10 and SAM L11 series, which may impact export or regulatory compliance depending on destination and application.

Q: What is the inventory status of substitute parts?

A: ATSAML10D15A-MUT has 34,402 units in stock. ATSAML11D15A-MUT has 6,875 units in stock. Inventory levels should be confirmed with the supplier for current availability.
