ES2HA Equivalent & Substitute Parts Reference

Part Overview

The ES2HA, manufactured by Taiwan Semiconductor Corporation, is a diode in the Diodes, Rectifiers category. Key features include 500 V maximum DC reverse voltage, 2A average rectified current, and a fast recovery time of 35 ns. The device is packaged in a DO-214AC (SMA) surface-mount case, has a maximum forward voltage of 1.7 V at 2 A, and a reverse leakage of 10 µA at 500 V. This part is in active production. For applications requiring identical electrical and mechanical performance, it is necessary to consider alternative models if inventory, sourcing, or lifecycle status (such as allocation or discontinuation at distributors) affects procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute and equivalent diodes for the ES2HA are selected strictly based on parameters including: maximum DC reverse voltage (500 V), average rectified current (2A), maximum forward voltage at rated current (1.7 V @ 2 A), fast recovery time (35 ns), maximum reverse leakage current (10 µA @ 500 V), capacitance, identical package and mounting type (DO-214AC, SMA, Surface Mount), operational temperature range, and compliance attributes (RoHS, MSL, REACH, ECCN, and HTSUS). Only devices matching all these criteria are considered valid substitutes in this category.

Parameter Comparison

Engineering Selection Recommendations

Both ES2HA and ES2HA R3G are produced by the same manufacturer and match all key electrical, mechanical, and compliance parameters. ES2HA is listed as active, while ES2HA R3G is discontinued at Digi-Key. Both parts are ROHS3 Compliant, moisture level 1 (unlimited), and REACH unaffected, with ECCN EAR99 and HTSUS 8541.10.0080.

Frequently Asked Questions (FAQ)

Q: What criteria are used to select substitute diodes for ES2HA?
A: Only parts with identical electrical ratings (voltage, current, speed, recovery time, reverse leakage, capacitance), matching surface-mount DO-214AC (SMA) package, and equivalent compliance are considered.

Q: Are ES2HA and ES2HA R3G interchangeable in circuit board designs?
A: Both have the same package, footprint, and electrical parameters, supporting direct interchange within the specified criteria.

Q: Does the discontinued status of ES2HA R3G affect compliance or compatibility?
A: Discontinued status affects only sourcing. Compliance and compatibility are determined strictly by listed technical and regulatory parameters.

Q: Is there any difference in environmental or safety certifications between ES2HA and ES2HA R3G?
A: Both parts are ROHS3 Compliant, have MSL 1 (unlimited), are REACH unaffected, and have the same ECCN and HTSUS codes.

Q: Does packaging type (Tape & Reel vs Cut Tape) affect substitutability?
A: Electrical and mechanical equivalence is maintained regardless of packaging, which only affects handling and assembly processes.
