ES1AL RHG Equivalent & Substitute Parts

Part Overview

The ES1AL RHG 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 a fast recovery diode with a reverse recovery time of 35 ns, suitable for standard rectification applications requiring rapid switching characteristics. The part maintains Active product status and carries full RoHS3 compliance with unlimited moisture sensitivity rating.

Substitute parts become necessary when the primary part number experiences inventory constraints, extended lead times, or when design flexibility permits selection from qualified alternatives meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ES1AL RHG is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 1 A
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Reverse Recovery Time (trr): Variations within fast recovery classification (≤ 500 ns for > 200 mA)
• Voltage - Forward (Vf) (Max) @ If: Consistent at 950 mV @ 1 A
• Current - Reverse Leakage @ Vr: Consistent at 5 µA @ 50 V
• Capacitance @ Vr, F: Minor variations acceptable within specified measurement conditions

The HS1AL RVG meets all mandatory matching criteria and qualifies as a parametric equivalent substitute for the ES1AL RHG.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: ES1AL RHG

The ES1AL RHG is the specified component with confirmed Active product status, full RoHS3 compliance, and REACH unaffected classification. Current inventory of 1161 pieces supports immediate availability for production requirements.

Substitute Part: HS1AL RVG

The HS1AL RVG qualifies as a direct parametric equivalent with identical electrical ratings, package configuration, and compliance certifications. This substitute maintains Active product status with higher inventory availability (2549 pieces), supporting extended production runs or supply chain continuity. The reverse recovery time of 50 ns remains within the fast recovery classification and does not exceed the maximum specification of 500 ns for currents exceeding 200 mA.

Both parts carry identical RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), confirming suitability for equivalent circuit applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can HS1AL RVG be used as a direct replacement for ES1AL RHG in existing designs?

A: Yes. Both parts share identical voltage ratings (50 V), current ratings (1 A), forward voltage characteristics (950 mV @ 1 A), package type (DO-219AB), and operating temperature range (-55°C to 150°C). The reverse recovery time difference (50 ns versus 35 ns) remains within the fast recovery classification and does not alter circuit performance for standard rectification applications.

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

A: The ES1AL RHG specifies 35 ns reverse recovery time while the HS1AL RVG specifies 50 ns. Both values fall within the fast recovery diode classification (≤ 500 ns for currents > 200 mA). This difference does not affect compatibility in applications where fast recovery characteristics are required but switching speed is not the limiting design parameter.

Q: Are the packaging and mounting specifications identical?

A: Yes. Both parts use the DO-219AB package with Sub SMA supplier device package designation and surface mount mounting type. PCB layout and assembly processes require no modification when substituting between these parts.

Q: Do compliance certifications differ between these parts?

A: No. Both ES1AL RHG and HS1AL RVG carry identical RoHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating. No additional compliance documentation or supply chain qualification is required for substitution.

Q: What is the difference in packaging format between the two parts?

A: The ES1AL RHG is supplied in standard packaging format, while the HS1AL RVG is supplied in Cut Tape (CT) format. Both formats contain identical components; the difference reflects only the physical delivery method and does not affect component electrical or mechanical properties.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: Both parts meet fast recovery diode specifications. The reverse recovery time difference (35 ns versus 50 ns) is within acceptable tolerance for standard rectification circuits. Application-specific switching frequency requirements should be evaluated against the provided reverse recovery time specifications.
