Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATECC108A-SSHCZ-B 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 layout and assembly compatibility.

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

Moisture Sensitivity: Moisture Sensitivity Level 3 (168 Hours) must be maintained to ensure proper handling and storage protocols.

Manufacturer Series: Parts within the CryptoAuthentication™ series from Microchip Technology are functionally compatible for authentication applications.

Product Status: Active status ensures ongoing manufacturer support and availability.

The ATECC608B-SSHCZ-B meets all these critical parameters and is classified as a manufacturer-recommended substitute.

Frequently Asked Questions (FAQ)

Q: Can the ATECC608B-SSHCZ-B be used as a direct replacement for the ATECC108A-SSHCZ-B?

A: Yes. Both devices share identical package specifications (8-SOIC), mounting type (surface mount), and regulatory compliance status (ROHS3, REACH Unaffected). The ATECC608B-SSHCZ-B is the manufacturer-recommended substitute.

Q: Are there any PCB layout changes required when substituting these parts?

A: No. Both parts use the same 8-SOIC package with 0.154" width and 3.90mm dimensions. PCB footprints and assembly processes remain unchanged.

Q: What is the significance of Moisture Sensitivity Level 3?

A: MSL 3 (168 Hours) indicates the maximum time the component can be exposed to ambient conditions of 30°C and 85% relative humidity before soldering. Both parts share this specification, ensuring identical handling and storage requirements.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the ATECC108A-SSHCZ-B and ATECC608B-SSHCZ-B are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: Which part should be selected based on availability?

A: Selection should be based on project requirements and inventory status. The ATECC608B-SSHCZ-B offers higher current inventory (7165 units) compared to the ATECC108A-SSHCZ-B (893 units).
