Parameter Comparison

Engineering Selection Recommendations

ATAES132A-SHER-T is the direct substitute for ATAES132-SH-ER-T based on matching electrical, mechanical, and functional parameters. The substitute part carries Active product status, ensuring long-term availability and supply chain continuity.

Compliance Consideration: The main part (ATAES132-SH-ER-T) is ROHS3 Compliant, while the substitute (ATAES132A-SHER-T) is RoHS non-compliant. Design teams must evaluate RoHS compliance requirements for their specific application and regional regulations before final component selection.

Both parts maintain REACH Unaffected status and identical ECCN/HTSUS classifications, confirming regulatory equivalence for export and trade purposes.

Frequently Asked Questions (FAQ)

Q: Can ATAES132A-SHER-T directly replace ATAES132-SH-ER-T on existing PCBs?

A: Yes. Both parts share identical package specifications (8-SOIC, 0.154" width), mounting type (Surface Mount), and functional classification (Authentication Chip). No PCB redesign is required for mechanical or electrical compatibility.

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

A: The main part is Obsolete with ROHS3 Compliance, while the substitute is Active with RoHS non-compliance. The Active status of ATAES132A-SHER-T ensures continued manufacturing and availability.

Q: Are there any compliance implications when switching from ATAES132-SH-ER-T to ATAES132A-SHER-T?

A: Yes. RoHS compliance status differs between the parts. Organizations subject to RoHS regulations must confirm that ATAES132A-SHER-T (RoHS non-compliant) meets their compliance obligations before adoption.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are the export classifications identical?

A: Yes. Both parts share ECCN 5A992C and HTSUS 8542.32.0051 classifications, confirming regulatory equivalence for international trade.
