ES1DVRX Equivalent & Substitute Parts

Part Overview

The ES1DVRX is a general-purpose rectifier diode manufactured by Nexperia USA Inc., rated for 200 V DC reverse voltage and 1 A average rectified current in a surface mount SOD-123W package. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain electrical performance within the specified parameter ranges while offering current availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES1DVRX is determined by strict equivalence across the following electrical and mechanical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 1 A
• Package / Case: SOD-123W
• Mounting Type: Surface Mount
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Allowable Parameter Variance:

• Voltage - Forward (Vf) (Max) @ If: Substitute values must not exceed the application's forward voltage tolerance
• Reverse Recovery Time (trr): Faster recovery times are acceptable; slower times require circuit validation
• Current - Reverse Leakage @ Vr: Higher leakage values are acceptable within circuit design margins
• Operating Temperature - Junction: Substitute range must encompass or exceed the maximum operating temperature of 150°C

The UF1DLW RVG manufactured by Taiwan Semiconductor Corporation meets all mandatory matching criteria and is therefore classified as a direct electrical and mechanical substitute for the ES1DVRX.

Engineering Selection Recommendations

ES1DVRX Status: Obsolete product with 1090 units in current inventory. Procurement of new stock is not available from the original manufacturer.

UF1DLW RVG Status: Discontinued at DiGi Electronics with 8679 units in current inventory. This substitute provides equivalent electrical performance and maintains full compliance with ROHS3 and REACH requirements.

Selection Basis:

The UF1DLW RVG is electrically and mechanically equivalent to the ES1DVRX across all mandatory parameters. Both components are rated for 200 V reverse voltage, 1 A average rectified current, and are packaged in SOD-123W surface mount form factor. Both meet fast recovery diode specifications and maintain identical maximum junction operating temperature of 150°C.

The UF1DLW RVG exhibits a forward voltage drop of 950 mV at 1 A compared to 875 mV for the ES1DVRX, representing a 75 mV increase. This variance must be evaluated within the specific circuit application to confirm acceptable power dissipation and voltage regulation performance.

The UF1DLW RVG demonstrates faster reverse recovery time (20 ns versus 25 ns), which provides improved switching performance characteristics. Higher reverse leakage current (1 µA versus 200 nA) and increased junction capacitance (40 pF versus 20 pF) are within acceptable ranges for general-purpose rectification applications.

Both components maintain identical RoHS3 compliance and REACH unaffected status, ensuring regulatory continuity in production environments.

Frequently Asked Questions (FAQ)

Q: Can the UF1DLW RVG be used as a direct replacement for the ES1DVRX in existing designs?

A: The UF1DLW RVG is electrically and mechanically equivalent across all mandatory parameters: 200 V reverse voltage rating, 1 A current rating, SOD-123W package, and surface mount configuration. The forward voltage difference of 75 mV must be evaluated within the specific circuit application to confirm acceptable performance.

Q: What is the significance of the forward voltage difference between these parts?

A: The ES1DVRX specifies 875 mV maximum forward voltage at 1 A, while the UF1DLW RVG specifies 950 mV at the same current. This 75 mV difference affects power dissipation and voltage regulation. Applications with tight voltage regulation requirements or high-current operation must verify that the higher forward voltage remains within acceptable design margins.

Q: Are there differences in switching performance between these diodes?

A: The UF1DLW RVG exhibits faster reverse recovery time (20 ns) compared to the ES1DVRX (25 ns). Both components meet the fast recovery classification of ≤ 500 ns for currents exceeding 200 mA. Faster recovery time in the substitute part provides improved switching characteristics and reduced switching losses.

Q: How do the leakage current specifications compare?

A: The ES1DVRX specifies 200 nA reverse leakage at 200 V, while the UF1DLW RVG specifies 1 µA at the same voltage. The higher leakage in the substitute part is acceptable for general-purpose rectification applications and does not impact standard circuit operation.

Q: Are both components compliant with current regulatory requirements?

A: Both the ES1DVRX and UF1DLW RVG are ROHS3 compliant and REACH unaffected. Both maintain identical regulatory status for production environments requiring compliance certification.

Q: What is the availability status of each component?

A: The ES1DVRX is obsolete with 1090 units in current inventory. The UF1DLW RVG is discontinued at DiGi Electronics with 8679 units in current inventory. Procurement planning should account for limited availability of both components.

Q: Are there package or mounting differences between these parts?

A: Both components use identical SOD-123W surface mount packaging. No modifications to PCB layout, footprint, or assembly processes are required for substitution.
