ES1ALHM2G Equivalent & Substitute Parts

Part Overview

The ES1ALHM2G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package. This component is classified as Active product status and meets automotive-grade qualification standards under AEC-Q101. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES1ALHM2G is permissible with parts meeting the following criteria:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A
• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• Grade: Automotive
• Qualification: AEC-Q101

The HS1AL RVG meets all critical electrical and mechanical parameters required for direct substitution. Both parts are manufactured by Taiwan Semiconductor Corporation, share identical voltage and current ratings, forward voltage characteristics, package designation, and automotive qualification status. Variations in reverse recovery time (trr) and junction capacitance fall within acceptable tolerances for general-purpose rectification applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ES1ALHM2G and HS1AL RVG are Active product status components with identical automotive-grade qualification (AEC-Q101) and full compliance with RoHS3 and REACH regulations. Selection between these parts is based on availability and packaging format:

ES1ALHM2G is suitable for applications requiring the specified packaging configuration with 1012 units currently in stock inventory.

HS1AL RVG provides equivalent electrical performance and is available in Cut Tape (CT) packaging format with 2549 units in stock inventory. This part is directly substitutable for the ES1ALHM2G in all circuit applications where the DO-219AB Sub SMA package and automotive qualification are required.

The minor difference in reverse recovery time (35 ns versus 50 ns) and junction capacitance (10 pF versus 20 pF) does not affect functional compatibility for general-purpose rectification circuits operating within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can HS1AL RVG replace ES1ALHM2G in automotive applications?

A: Yes. Both parts carry AEC-Q101 automotive qualification, identical voltage and current ratings (50 V, 1 A), matching forward voltage characteristics (950 mV @ 1 A), and the same DO-219AB Sub SMA package. Automotive-grade compliance is maintained with either part.

Q: What is the difference in reverse recovery time between these parts?

A: The ES1ALHM2G has a reverse recovery time of 35 ns, while the HS1AL RVG has 50 ns. Both parts meet the Fast Recovery classification (≤ 500 ns for currents > 200 mA). This difference does not affect circuit operation in standard rectification applications.

Q: Are there packaging differences between ES1ALHM2G and HS1AL RVG?

A: Both parts use the DO-219AB Sub SMA package for surface mount applications. The primary difference is the supplier packaging format: ES1ALHM2G is supplied in standard packaging, while HS1AL RVG is supplied in Cut Tape (CT) format. The component itself and PCB footprint are identical.

Q: Do both parts meet RoHS and REACH compliance?

A: Yes. Both ES1ALHM2G and HS1AL RVG are ROHS3 Compliant and REACH Unaffected, with Moisture Sensitivity Level 1 (Unlimited), suitable for unrestricted storage and handling.

Q: What is the junction capacitance difference, and does it matter?

A: The ES1ALHM2G has 10 pF capacitance at 4 V, 1 MHz, while HS1AL RVG has 20 pF at the same conditions. For general-purpose rectification circuits, this difference is not functionally significant. High-frequency switching applications should verify circuit performance if capacitance is a critical design parameter.
