ATECC508A-MAHAW-S Equivalent & Substitute Parts

Part Overview

The ATECC508A-MAHAW-S is an authentication chip manufactured by Microchip Technology, part of the CryptoAuthentication™ series. This surface-mount integrated circuit is designed for networking and communications applications requiring secure authentication functionality. The device is packaged in an 8-UDFN (2x3) form factor with exposed pad and is currently in active product status with ROHS3 compliance and REACH unaffected classification. Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and regulatory compliance are maintained across alternative part numbers.

Substitute Part Grouping Explanation

Substitution eligibility for the ATECC508A-MAHAW-S is determined by strict alignment of the following parameters:

Critical Substitution Criteria:

• Identical package type: 8-UFDFN Exposed Pad
• Identical supplier device package: 8-UDFN (2x3)
• Identical mounting type: Surface Mount
• Identical series classification: CryptoAuthentication™
• Identical type designation: Authentication Chip
• Matching RoHS compliance: ROHS3 Compliant
• Matching moisture sensitivity level: MSL 3 (168 Hours)
• Matching REACH status: REACH Unaffected
• Matching export classification: ECCN 5A992C
• Matching tariff classification: HTSUS 8542.39.0001
• Active product status maintained

The ATECC608B-MAHDA-S meets all substitution criteria as a manufacturer-recommended equivalent. Both parts share identical mechanical, electrical interface, and regulatory compliance specifications, differing only in base product number designation and packaging format (Cut Tape & Digi-Reel® versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

Both the ATECC508A-MAHAW-S and ATECC608B-MAHDA-S are active products with identical regulatory compliance profiles. Selection between these parts is based on packaging and supply format requirements:

ATECC508A-MAHAW-S is appropriate for applications requiring Tape & Reel packaging format with current inventory availability of 721 pieces.

ATECC608B-MAHDA-S is the manufacturer-recommended substitute, offering Cut Tape and Digi-Reel® packaging options with significantly higher inventory availability of 152,500 pieces. This part maintains full electrical, mechanical, and regulatory equivalence.

Both parts satisfy ROHS3 compliance, REACH unaffected status, and identical MSL 3 moisture sensitivity specifications. Selection should be based on packaging format compatibility with assembly processes and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can ATECC608B-MAHDA-S be used as a direct replacement for ATECC508A-MAHAW-S?

A: Yes. Both parts are identical in electrical interface, mechanical package dimensions (8-UDFN 2x3 with exposed pad), mounting type (surface mount), and regulatory compliance. The difference is limited to packaging format and base product number designation.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) provides components on continuous carrier tape in reel format for high-volume automated assembly. Cut Tape (CT) provides the same carrier tape cut into smaller quantities. Digi-Reel® is a proprietary packaging format. Both formats contain identical components with the same electrical and mechanical specifications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts share identical RoHS3 compliance, REACH unaffected status, MSL 3 (168 Hours) moisture sensitivity level, ECCN 5A992C export classification, and HTSUS 8542.39.0001 tariff classification.

Q: What factors determine substitution eligibility for authentication chips?

A: Substitution requires matching package type, pin configuration, mounting method, series designation, regulatory compliance certifications, moisture sensitivity level, and export/tariff classifications. Electrical interface compatibility is implicit in identical package specifications for this component category.

Q: Is inventory availability a factor in substitution decisions?

A: Inventory availability is a supply chain consideration but not a technical substitution criterion. Both parts are active products with equivalent specifications. Selection may be influenced by supply requirements and lead time considerations.
