Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATSHA204-TH-DA-T is determined by the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Microchip Technology
• Series: CryptoAuthentication™
• Type: Authentication Chip
• Package / Case: 8-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• Applications: Networking and Communications
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The ATSHA204A-XHDA-T qualifies as a direct substitute based on full alignment with all mandatory parameters. The primary distinction is product status: ATSHA204A-XHDA-T maintains Active status, providing superior supply chain availability compared to the Obsolete ATSHA204-TH-DA-T.

Parameter Comparison

Engineering Selection Recommendations

ATSHA204A-XHDA-T is the direct substitute for ATSHA204-TH-DA-T based on the following engineering criteria:

1. Product Status Alignment: ATSHA204A-XHDA-T maintains Active product status, ensuring long-term availability and manufacturer support. The ATSHA204-TH-DA-T Obsolete status creates supply chain risk.

2. Compliance Certification: Both parts maintain identical RoHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for new designs and production continuity.

3. Package and Mounting Compatibility: Identical 8-TSSOP package specifications and surface mount characteristics ensure direct PCB-level compatibility without layout modifications.

4. Functional Classification: Both parts belong to the CryptoAuthentication™ series and serve identical authentication chip applications in networking and communications systems.

5. Environmental Specifications: Matching MSL Level 1 (Unlimited) moisture sensitivity ensures equivalent handling and storage requirements.

Selection of ATSHA204A-XHDA-T eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing designs.
