ESGLW RVG Equivalent & Substitute Parts

Part Overview

The ESGLW RVG is a general-purpose fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage and 800 mA average rectified current in a surface mount SOD-123W package. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, packaging format preferences, or application-specific qualification requirements such as automotive grade certification.

Substitute Part Grouping Explanation

Substitution of the ESGLW RVG is determined by equivalence in the following critical parameters: maximum reverse voltage (400 V), average rectified current (800 mA), forward voltage drop (1.3 V @ 800 mA), reverse recovery time (35 ns), reverse leakage current (1 µA @ 400 V), and package type (SOD-123W surface mount). Substitute parts are grouped into two categories:

Category 1: Parametric Equivalents with Packaging Variation Parts ESGLW and ESGLWH maintain identical electrical specifications to ESGLW RVG but differ in packaging format (Tape & Reel instead of Cut Tape). ESGLWH includes automotive grade qualification (AEC-Q101).

Category 2: Parametric Equivalents with Automotive Qualification Part ESGLWHRVG is supplied in Tape & Reel format with automotive grade and AEC-Q101 qualification, maintaining all electrical parameters identical to the main part.

Category 3: Cross-Manufacturer Equivalent with Parameter Variance Part RS1GFA (onsemi) meets the primary voltage and current ratings but exhibits differences in reverse recovery time (250 ns versus 35 ns), reverse leakage current (5 µA versus 1 µA), and capacitance (10 pF versus 20 pF). This part carries automotive grade and AEC-Q101 qualification but is classified as Not For New Designs.

Engineering Selection Recommendations

For Standard Applications (Non-Automotive): ESGLW (Tape & Reel format) is a direct substitute for ESGLW RVG when packaging format change from Cut Tape to Tape & Reel is acceptable. Both parts maintain identical electrical specifications and Active product status.

For Automotive Applications: ESGLWH and ESGLWHRVG are qualified substitutes for automotive-grade applications, both carrying AEC-Q101 qualification and Active product status. These parts maintain all electrical parameters identical to the main part while providing automotive-grade certification in Tape & Reel packaging.

For Legacy or Constrained Applications: RS1GFA (onsemi) is a cross-manufacturer substitute that meets voltage and current requirements but exhibits degraded performance in reverse recovery time (250 ns versus 35 ns), increased reverse leakage current (5 µA versus 1 µA), and reduced capacitance (10 pF versus 20 pF). This part is classified as Not For New Designs and should be used only when no other alternatives are available. Applications sensitive to switching speed or leakage current characteristics must evaluate compatibility independently.

Frequently Asked Questions (FAQ)

Q: Can ESGLW (Tape & Reel) be used as a direct replacement for ESGLW RVG (Cut Tape)?

A: Yes. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain identical electrical specifications including voltage rating (400 V), current rating (800 mA), forward voltage (1.3 V @ 800 mA), reverse recovery time (35 ns), and reverse leakage current (1 µA @ 400 V). The difference is packaging format: ESGLW RVG is supplied in Cut Tape while ESGLW is supplied in Tape & Reel. Component-level performance is equivalent.

Q: What is the difference between ESGLWH and ESGLWHRVG?

A: Both ESGLWH and ESGLWHRVG are manufactured by Taiwan Semiconductor Corporation and maintain identical electrical specifications and automotive AEC-Q101 qualification. The primary difference is the part number designation; ESGLWHRVG includes "RVG" in the part number. Both are supplied in Tape & Reel format and are suitable for automotive applications.

Q: Is RS1GFA a suitable substitute for ESGLW RVG?

A: RS1GFA (onsemi) meets the primary voltage (400 V) and current (800 mA) ratings and maintains the same forward voltage specification (1.3 V @ 800 mA). However, RS1GFA exhibits significant differences in secondary parameters: reverse recovery time is 250 ns (versus 35 ns for ESGLW RVG), reverse leakage current is 5 µA (versus 1 µA), and capacitance is 10 pF (versus 20 pF). Additionally, RS1GFA is classified as Not For New Designs. Substitution is limited to applications where these parameter differences do not impact circuit performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. ESGLW, ESGLWH, ESGLWHRVG, and RS1GFA are all ROHS3 compliant. All parts also maintain Moisture Sensitivity Level 1 (Unlimited) classification.

Q: What packaging considerations apply when selecting a substitute?

A: ESGLW RVG is supplied in Cut Tape (CT) format. Substitute parts ESGLW, ESGLWH, ESGLWHRVG, and RS1GFA are supplied in Tape & Reel (TR) format. The SOD-123W package footprint is identical across all parts, ensuring mechanical compatibility on printed circuit boards. Packaging format selection depends on assembly equipment and procurement requirements rather than electrical performance.

Q: Which substitute part is recommended for new automotive designs?

A: ESGLWH and ESGLWHRVG are the recommended substitutes for new automotive designs. Both parts carry AEC-Q101 automotive qualification, maintain Active product status, and provide identical electrical specifications to ESGLW RVG. RS1GFA, while automotive qualified, is classified as Not For New Designs and should not be selected for new development.
