ATSHA204-RBH-T Equivalent & Substitute Parts

Part Overview

The ATSHA204-RBH-T is an authentication chip manufactured by Microchip Technology, part of the CryptoAuthentication™ series. This component is designed for networking and communications applications requiring secure authentication functionality. The device features a 3-SMD, No Lead package configuration suitable for surface mount assembly.

The ATSHA204-RBH-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 ATSHA204A-RBHCZ-T serves as the direct successor with Active product status.

Key Parameters

Substitute Part Grouping Explanation

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

Functional Equivalence: Both the main part and substitute must belong to the CryptoAuthentication™ series and serve as authentication chips for networking and communications applications.

Package Compatibility: The substitute must utilize the identical 3-SMD, No Lead package configuration to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Mounting Technology: Surface mount mounting type must be maintained across all substitute parts.

Compliance Requirements: RoHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) rating must be preserved to meet regulatory and environmental standards.

Manufacturer Consistency: All substitute parts must originate from Microchip Technology to ensure design continuity and technical support alignment.

The ATSHA204A-RBHCZ-T meets all substitution criteria and represents the direct evolutionary upgrade within the product family.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The ATSHA204A-RBHCZ-T is the appropriate selection. This part carries Active product status, ensuring long-term availability, ongoing manufacturer support, and compliance with current supply chain requirements. Active status guarantees continued production and technical documentation updates.

For Legacy System Maintenance: The ATSHA204-RBH-T remains functionally equivalent for existing applications. However, due to Obsolete status, inventory availability is finite. Transition planning to ATSHA204A-RBHCZ-T is recommended for future production runs.

Compliance Assurance: Both parts maintain identical RoHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for EU and international markets. MSL 1 (Unlimited) rating indicates no moisture sensitivity constraints during storage or handling.

Supply Chain Continuity: The ATSHA204A-RBHCZ-T is available in Cut Tape (CT) and Digi-Reel® packaging formats with 3200 units in current inventory, supporting volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can ATSHA204A-RBHCZ-T directly replace ATSHA204-RBH-T in existing designs?

A: Yes. Both parts share identical package configuration (3-SMD, No Lead), mounting type (Surface Mount), and functional classification (Authentication Chip). PCB layouts and assembly processes require no modification.

Q: What is the primary difference between these two parts?

A: The ATSHA204A-RBHCZ-T represents the current Active product generation, while ATSHA204-RBH-T is Obsolete. Both maintain equivalent electrical and mechanical specifications within the CryptoAuthentication™ series.

Q: Are there packaging format differences?

A: The ATSHA204-RBH-T is specified with standard packaging, while ATSHA204A-RBHCZ-T is available in Cut Tape (CT) and Digi-Reel® formats. Both formats accommodate automated assembly processes.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints. Standard storage conditions apply to both variants.

Q: Is regulatory compliance identical between the two parts?

A: Yes. Both parts maintain ROHS3 compliance and REACH Unaffected status. No additional compliance verification is required when substituting between these parts.

Q: Why should new designs use ATSHA204A-RBHCZ-T instead of ATSHA204-RBH-T?

A: Active product status ensures manufacturer support, continued availability, and long-term supply chain stability. Obsolete parts face eventual discontinuation and inventory depletion.
