Substitute Part Grouping Explanation

Substitution of the ATECC108-SSHCZ-B is determined by the following criteria:

Electrical and Mechanical Compatibility:

• Identical package type: 8-SOIC (0.154", 3.90mm Width)
• Identical mounting type: Surface Mount
• Same base product series: CryptoAuthentication™
• Same functional classification: Authentication Chip
• Identical application domain: Networking and Communications

Compliance Requirements:

• RoHS3 Compliance maintained
• REACH Unaffected status maintained

The ATECC108A-SSHCZ-B meets all substitution criteria as a direct equivalent, sharing identical physical packaging, electrical interface requirements, and regulatory compliance status. The primary distinction is product lifecycle status: ATECC108-SSHCZ-B is obsolete, while ATECC108A-SSHCZ-B is active.
