ATSHA204-MAH-CZ-T Equivalent & Substitute Parts

Part Overview

The ATSHA204-MAH-CZ-T is an authentication chip manufactured by Microchip Technology in the CryptoAuthentication™ series. This component is designed for networking and communications applications requiring secure authentication functionality. The device is packaged in an 8-UFDFN (2x3) surface mount configuration with an exposed pad.

The ATSHA204-MAH-CZ-T carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, production continuity, and long-term system support. The substitute part ATSHA204A-MAHCZ-T provides functional equivalence while maintaining Active product status.

Substitute Part Grouping Explanation

Substitution between the ATSHA204-MAH-CZ-T and ATSHA204A-MAHCZ-T is valid based on the following criteria:

Matching Parameters:

• Identical manufacturer (Microchip Technology)
• Identical series (CryptoAuthentication™)
• Identical component type (Authentication Chip)
• Identical package configuration (8-UFDFN Exposed Pad, 8-UDFN (2x3))
• Identical mounting type (Surface Mount)
• Identical application domain (Networking and Communications)
• Identical RoHS compliance status (ROHS3 Compliant)
• Identical moisture sensitivity level (MSL 1 - Unlimited)
• Identical REACH status (REACH Unaffected)

The primary distinction between these parts is product lifecycle status: the original part is Obsolete, while the substitute maintains Active status. Both parts share the same base product number (ATSHA204) and are functionally equivalent within the CryptoAuthentication™ authentication chip family.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The ATSHA204A-MAHCZ-T is the appropriate selection. This part maintains Active product status from Microchip Technology, ensuring long-term availability, ongoing manufacturing support, and compliance with current regulatory requirements. The higher inventory level (10,300 units) provides supply chain stability.

For Existing Inventory Management: The ATSHA204-MAH-CZ-T remains functionally equivalent for applications already in production. However, transition planning to the ATSHA204A-MAHCZ-T is recommended to avoid obsolescence-related supply disruptions.

Compliance Considerations: Both parts maintain identical ROHS3 compliance and REACH Unaffected status, ensuring regulatory equivalence for applications subject to these standards.

Frequently Asked Questions (FAQ)

Q: Can ATSHA204A-MAHCZ-T directly replace ATSHA204-MAH-CZ-T in existing designs?
