Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATSHA204-MAH-DA-T is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Microchip Technology
• Series: CryptoAuthentication™
• Type: Authentication Chip
• Package / Case: 8-UFDFN Exposed Pad
• Supplier Device Package: 8-UDFN (2x3)
• Mounting Type: Surface Mount
• Applications: Networking and Communications
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The ATSHA204A-MAHDA-T meets all mandatory matching parameters and qualifies as a direct substitute. The primary distinction is product status: the ATSHA204A-MAHDA-T maintains active manufacturing status, ensuring ongoing availability and supply chain continuity.
