Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATECC108-SSHCZ-T is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure PCB footprint and assembly process compatibility.

Functional Classification: The substitute must be classified as an Authentication Chip within the CryptoAuthentication™ series to maintain functional equivalence in networking and communications applications.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and REACH Unaffected status to satisfy environmental and regulatory requirements.

Manufacturer Consistency: Microchip Technology manufactures both the original and substitute parts, ensuring design continuity and technical support alignment.

The ATECC108A-SSHCZ-T meets all substitution criteria and is identified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The ATECC108A-SSHCZ-T is the appropriate selection. This part carries Active product status, ensuring long-term availability and manufacturer support. It maintains identical package, functional classification, and regulatory compliance with the obsolete ATECC108-SSHCZ-T.

For Existing Inventory Management: The ATECC108-SSHCZ-T remains functional for current applications. However, transition planning to ATECC108A-SSHCZ-T is recommended to avoid supply chain disruption as obsolete inventory depletes.

Compliance Considerations: Both parts satisfy ROHS3 and REACH requirements. The ATECC108A-SSHCZ-T specifies Moisture Sensitivity Level 3 (168 Hours), requiring standard moisture control during storage and handling compared to the unlimited MSL of the obsolete variant.

Frequently Asked Questions (FAQ)

Q: Can ATECC108A-SSHCZ-T directly replace ATECC108-SSHCZ-T on existing PCBs?
