Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATECC508A-SSHAW-T is determined by strict adherence to the following parameters:

Primary Compatibility Criteria:

• Manufacturer: Microchip Technology
• Series: CryptoAuthentication™
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Packaging Format: Cut Tape (CT) & Digi-Reel®
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The ATECC508A-SSHAW-T is substitutable with parts that maintain identical electrical interface characteristics, mechanical form factor, and regulatory compliance status. The authentication chip category requires that substitute components preserve the same package geometry, pin configuration, and surface mount compatibility to ensure direct board-level replacement without design modification.

Parameter Comparison

Engineering Selection Recommendations

Both the ATECC508A-SSHAW-T and ATECC608B-SSHDA-T maintain Active product status within the Microchip Technology CryptoAuthentication™ series. Both components are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for industrial and commercial applications.

The primary distinction between these parts is the Moisture Sensitivity Level (MSL) specification. The ATECC508A-SSHAW-T carries MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. The ATECC608B-SSHDA-T carries MSL 3 (168 Hours), requiring controlled moisture exposure conditions during manufacturing and assembly operations.

Component selection should account for manufacturing environment capabilities and storage conditions. Both parts share identical package geometry (8-SOIC), mounting type (Surface Mount), and packaging format (Cut Tape & Digi-Reel®), ensuring mechanical and electrical compatibility at the board level.

Frequently Asked Questions (FAQ)

Q: Can the ATECC608B-SSHDA-T directly replace the ATECC508A-SSHAW-T on a printed circuit board?

A: Yes. Both components utilize identical 8-SOIC package geometry with 0.154" width and 3.90mm dimensions. Pin configuration and surface mount footprint are compatible, enabling direct substitution without PCB redesign.

Q: What is the significance of the MSL rating difference between these parts?

A: MSL 1 (Unlimited) indicates the ATECC508A-SSHAW-T has no moisture sensitivity restrictions. MSL 3 (168 Hours) for the ATECC608B-SSHDA-T requires that the component be exposed to moisture-controlled conditions for no more than 168 cumulative hours before soldering. Manufacturing facilities must implement appropriate bake-out procedures if storage exceeds this threshold.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the ATECC508A-SSHAW-T and ATECC608B-SSHDA-T are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance restrictions for industrial applications.

Q: What packaging formats are available for these authentication chips?

A: Both parts are supplied in Cut Tape (CT) and Digi-Reel® formats, supporting automated assembly processes and component handling systems.

Q: Are there inventory considerations when selecting between these substitutes?

A: The ATECC608B-SSHDA-T maintains significantly higher inventory (691,200 pieces) compared to the ATECC508A-SSHAW-T (33,300 pieces), which may influence availability and lead time for high-volume production requirements.
