Engineering Selection Recommendations

ES2AA-13-F (Diodes Incorporated) is the direct functional equivalent for the ES2A-LTP. Both parts share identical voltage and current ratings (50V/2A), matching package configuration (DO-214AC/SMA), and equivalent forward voltage characteristics. ES2AA-13-F carries Active product status, ensuring long-term availability and supply continuity. This part is recommended for direct replacement in applications where the original 50V rating is specified and sufficient.

MURA210T3G (onsemi) provides a higher voltage rating (100V) while maintaining the 2A current specification. This part is suitable for applications where voltage margin enhancement is beneficial or where circuit design permits operation at elevated voltage ratings. MURA210T3G also carries Active product status and maintains the same operating temperature range (-65°C ~ 175°C) as the original ES2A-LTP. The lower reverse recovery time (30 ns versus 35 ns) and reduced reverse leakage current at its rated voltage represent improved performance characteristics.

Both substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity classification, and surface mount DO-214AC (SMA) package compatibility, ensuring mechanical and environmental compliance equivalence with the original component.

Frequently Asked Questions (FAQ)

Q: Can ES2AA-13-F be used as a direct replacement for ES2A-LTP?

A: Yes. ES2AA-13-F meets all electrical and mechanical requirements for direct substitution. Both parts are rated 50V/2A, use identical DO-214AC (SMA) packaging, and share equivalent forward voltage characteristics. ES2AA-13-F is an Active product, providing improved supply availability compared to the Not For New Designs status of ES2A-LTP.

Q: What is the difference between ES2AA-13-F and MURA210T3G?

A: The primary difference is voltage rating. ES2AA-13-F maintains the original 50V specification, while MURA210T3G is rated for 100V. Both support 2A current and use DO-214AC (SMA) packaging. MURA210T3G is appropriate when higher voltage margin is required or when circuit design permits operation at elevated voltage ratings.

Q: Are there temperature range differences between the substitute parts and the original ES2A-LTP?

A: ES2AA-13-F operates over -55°C ~ 150°C, which is narrower than the original ES2A-LTP range of -65°C ~ 175°C. MURA210T3G maintains the full -65°C ~ 175°C range. Temperature range selection depends on application requirements.

Q: Do all substitute parts use the same package?

A: Yes. ES2A-LTP, ES2AA-13-F, and MURA210T3G all use DO-214AC (SMA) surface mount packaging, ensuring mechanical compatibility and identical PCB footprint.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both ES2AA-13-F and MURA210T3G are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity classification, matching the compliance profile of the original ES2A-LTP.

Q: Which substitute part should be selected for new designs?

A: Both ES2AA-13-F and MURA210T3G carry Active product status and are suitable for new designs. ES2AA-13-F is recommended when the 50V rating is specified. MURA210T3G is recommended when higher voltage rating or improved performance characteristics (lower reverse recovery time, reduced leakage current) are beneficial to circuit operation.
