Engineering Selection Recommendations

The AS431ANTR-G1 is the manufacturer-recommended substitute for the obsolete AJS431ANTR-E1. Selection of the AS431ANTR-G1 is supported by:

• Product Status: The AS431ANTR-G1 maintains Active status with established manufacturing and supply chain support, eliminating obsolescence risk
• Regulatory Compliance: Both parts satisfy ROHS3 and REACH requirements, ensuring compliance with current environmental and safety standards
• Physical Compatibility: Identical SOT-23-3 packaging enables direct PCB-level replacement without layout modifications
• Manufacturer Support: Diodes Incorporated provides ongoing technical documentation and production continuity for the AS431ANTR-G1

The transition from AJS431ANTR-E1 to AS431ANTR-G1 addresses obsolescence while maintaining functional and regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the AS431ANTR-G1 directly replace the AJS431ANTR-E1 on existing PCBs?

A: Yes. Both parts use identical SOT-23-3 packaging, enabling direct physical replacement without PCB layout modifications.

Q: What is the primary reason for substitution?

A: The AJS431ANTR-E1 is designated as Obsolete. The AS431ANTR-G1 is the manufacturer-recommended Active alternative, ensuring continued availability and production support.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 Compliant and REACH Unaffected. The primary compliance difference is Moisture Sensitivity Level: AJS431ANTR-E1 is MSL 1 (Unlimited), while AS431ANTR-G1 is MSL 3 (168 Hours). This requires appropriate handling and storage protocols for the substitute part.

Q: Is the AS431ANTR-G1 available in the same packaging options?

A: The AS431ANTR-G1 is available in Cut Tape (CT) and Digi-Reel® packaging formats, with the component specified as SOT-23-3 package type.

Q: What is the manufacturer recommendation for this substitution?

A: Diodes Incorporated designates AS431ANTR-G1 as the recommended manufacturer substitute for the obsolete AJS431ANTR-E1, confirming functional and electrical equivalence within the product family.
