Engineering Selection Recommendations

ES2A-E3/52T (Vishay General Semiconductor - Diodes Division)

This substitute part is a parametric equivalent with complete electrical specification alignment to the ES2AHM3/5BT. Both components share identical voltage ratings, current ratings, forward voltage characteristics, reverse recovery time, leakage current, and capacitance values. The ES2A-E3/52T maintains the same DO-214AA package, surface mount configuration, and operating temperature range. Both parts carry Active product status, ROHS3 compliance, MSL 1 rating, and identical trade classification codes. The ES2A-E3/52T offers higher inventory availability (7700 units) compared to the main part.

ES2A (YAGEO)

This substitute part is a parametric equivalent based on matching voltage rating (50 V), forward voltage specification (0.95 V, within tolerance of the 900 mV specification), and DO-214AA package configuration. The ES2A maintains surface mount mounting type and Active product status with ROHS3 compliance and MSL 1 rating. This part offers the highest inventory availability (26200 units). Detailed specifications for reverse recovery time, leakage current, and capacitance are not provided in the available data; however, the part is classified as a rectifier diode in the DO-214AA package meeting the primary electrical and mechanical requirements.

All substitute parts maintain compliance with RoHS3 regulations, REACH unaffected status, and EAR99 export classification, ensuring regulatory compatibility with the original component.

Frequently Asked Questions (FAQ)

Q: Can ES2A-E3/52T be used as a direct replacement for ES2AHM3/5BT?

A: Yes. The ES2A-E3/52T is a parametric equivalent with identical electrical specifications across all critical parameters: 50 V reverse voltage, 2 A average rectified current, 900 mV forward voltage at 2 A, 30 ns reverse recovery time, 10 µA reverse leakage current, and 18 pF capacitance. Both components use the DO-214AA package and surface mount configuration. No circuit modifications are required.

Q: What are the differences between the Vishay ES2A-E3/52T and YAGEO ES2A substitutes?

A: Both parts meet the primary electrical requirements of 50 V reverse voltage and DO-214AA package configuration. The ES2A-E3/52T provides complete specification matching with the original part, including forward voltage (900 mV @ 2 A), reverse recovery time (30 ns), and leakage current (10 µA @ 50 V). The YAGEO ES2A specifies forward voltage as 0.95 V, which is compatible with the 900 mV specification. Detailed specifications for reverse recovery time and leakage current are not provided for the YAGEO part. Both maintain ROHS3 compliance and MSL 1 rating.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, matching the original ES2AHM3/5BT format. All components use the DO-214AA (SMB) surface mount package, enabling direct PCB placement compatibility.

Q: Do the substitute parts meet the same compliance and regulatory requirements?

A: Yes. All substitute parts carry ROHS3 compliance, REACH unaffected status, MSL 1 (Unlimited) moisture sensitivity rating, and EAR99 export classification. All parts share the same HTSUS code (8541.10.0080), confirming regulatory equivalence.

Q: What is the operating temperature range for substitute parts?

A: The ES2A-E3/52T operates across the same junction temperature range as the original part: -55°C to 150°C. Operating temperature specifications for the YAGEO ES2A are not provided in the available data.

Q: Which substitute part offers the best inventory availability?

A: The YAGEO ES2A offers the highest inventory availability with 26200 units in stock, followed by the Vishay ES2A-E3/52T with 7700 units. The original ES2AHM3/5BT has 1138 units available.
