ES1AL MHG Equivalent & Substitute Parts

Part Overview

The ES1AL MHG 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 (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including voltage rating, current capacity, package type, and thermal operating range. Identifying qualified substitutes ensures design flexibility, supply chain continuity, and component availability without requiring circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Equivalence Criteria:

• 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
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation Parameters:

• Reverse Recovery Time (trr): Variation permitted within fast recovery classification (≤ 500 ns)
• Current - Reverse Leakage @ Vr: Variation permitted within specified tolerance
• Capacitance @ Vr, F: Variation permitted based on measurement frequency and voltage conditions

The HS1AL RVG meets all mandatory equivalence criteria and qualifies as a direct parametric equivalent substitute for the ES1AL MHG.

Engineering Selection Recommendations

Primary Selection: ES1AL MHG

The ES1AL MHG is the specified component and maintains Active product status with full regulatory compliance. Current inventory of 918 pieces supports immediate procurement for production requirements.

Substitute Selection: HS1AL RVG

The HS1AL RVG qualifies as a direct parametric equivalent substitute. Both components are manufactured by Taiwan Semiconductor Corporation and share identical electrical ratings, package specifications, and compliance certifications. The HS1AL RVG exhibits a reverse recovery time of 50 ns compared to 35 ns for the ES1AL MHG; both values remain within the fast recovery classification (≤ 500 ns). This variation does not affect functional compatibility in standard rectification applications.

The HS1AL RVG maintains Active product status and carries ROHS3 compliance with MSL 1 rating, matching the ES1AL MHG across all regulatory and environmental requirements. Higher inventory availability (2549 pieces) for the HS1AL RVG may provide supply chain advantages.

Both components are suitable for direct substitution in circuit designs without modification to PCB layout, thermal management, or electrical circuit parameters.

Frequently Asked Questions (FAQ)

Q: Can the HS1AL RVG replace the ES1AL MHG in existing designs?

A: Yes. The HS1AL RVG is a direct parametric equivalent substitute. Both components share identical voltage ratings (50 V), current capacity (1 A), forward voltage drop (950 mV @ 1 A), package type (DO-219AB Sub SMA), and operating temperature range (-55°C to 150°C). No circuit modifications are required.

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

A: The ES1AL MHG specifies 35 ns reverse recovery time, while the HS1AL RVG specifies 50 ns. Both values fall within the fast recovery diode classification (≤ 500 ns). This difference does not affect functional performance in standard rectification applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ES1AL MHG and HS1AL RVG carry ROHS3 compliance certification and are REACH Unaffected. Both components maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the package compatibility between these parts?

A: Both components use the DO-219AB package with Sub SMA supplier device package designation. They are mechanically and electrically compatible for surface mount PCB assembly without footprint modification.

Q: Which part should be selected for new designs?

A: Either component is suitable for new designs. Selection may be based on inventory availability, supplier lead time, or packaging preference (ES1AL MHG is supplied in standard packaging; HS1AL RVG is supplied in Cut Tape). Both maintain identical electrical performance and regulatory compliance.

Q: Are there any thermal performance differences?

A: Both components share identical operating temperature ranges (-55°C to 150°C junction temperature). No thermal performance differentiation exists between the ES1AL MHG and HS1AL RVG.
