ES1JLHRUG Equivalent & Substitute Parts

Part Overview

The ES1JLHRUG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 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 carries AEC-Q101 automotive qualification with ROHS3 compliance.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or alternative packaging formats are required for manufacturing optimization. The ES1JLHRUG maintains parametric equivalence with select alternatives that share identical electrical ratings and mechanical compatibility within the DO-219AB package family.

Substitute Part Grouping Explanation

Substitution eligibility for the ES1JLHRUG is determined by strict parametric matching across the following critical criteria:

Mandatory Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 600 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 1 A
Package / Case: DO-219AB
Supplier Device Package: Sub SMA
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): Variations permitted within fast recovery classification (≤500 ns for >200 mA)
Capacitance @ Vr, F: Variations permitted within specified frequency and voltage conditions
Current - Reverse Leakage @ Vr: Variations permitted at rated voltage
Packaging Format: Tape & Reel (TR), Cut Tape (CT), or Digi-Reel® formats are interchangeable for the same electrical device
Product Status: Active and Not For New Designs classifications both qualify for substitution

Two substitute parts meet these criteria: ES1JL and HS1JL RVG, both manufactured by Taiwan Semiconductor Corporation in the DO-219AB package.

Engineering Selection Recommendations

ES1JL Substitute: The ES1JL is a parametric equivalent to the ES1JLHRUG with identical electrical specifications and reverse recovery time of 35 ns. This part carries a "Not For New Designs" product status designation, indicating it is suitable for replacement and legacy system support but not recommended for new product development. The ES1JL is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for manufacturing processes that do not require Tape & Reel format. Selection of ES1JL is appropriate for field replacements, repair operations, and production continuity when ES1JLHRUG inventory is unavailable.

HS1JL RVG Substitute: The HS1JL RVG maintains full parametric equivalence across all mandatory electrical ratings and thermal specifications. This part carries Active product status, indicating ongoing manufacturer support and suitability for new designs. The HS1JL RVG exhibits a reverse recovery time of 75 ns and capacitance of 15 pF at 4V, 1MHz, both within allowable variation parameters for fast recovery rectifier diodes. The HS1JL RVG is available in Cut Tape (CT) packaging format. Selection of HS1JL RVG is appropriate for applications requiring long-term component availability and manufacturer support.

Both substitute parts maintain ROHS3 compliance, AEC-Q101 automotive qualification equivalence, and identical thermal operating ranges. Packaging format differences do not affect electrical performance or mechanical fit within the DO-219AB footprint.

Frequently Asked Questions (FAQ)

Q: Can ES1JL be used as a direct replacement for ES1JLHRUG in production?

A: Yes. The ES1JL is a parametric equivalent with identical voltage, current, forward voltage, and reverse leakage specifications. Both parts use the DO-219AB package and Sub SMA supplier device package. The primary difference is packaging format (Cut Tape/Digi-Reel® versus Tape & Reel) and product status classification. Electrical performance and mechanical compatibility are equivalent.

Q: What is the significance of the "Not For New Designs" status on ES1JL?

A: This designation indicates the manufacturer is not actively promoting this part number for new product development. However, it remains available for replacement, repair, and legacy system support. The part maintains full compliance with ROHS3 and AEC-Q101 standards. Selection depends on project lifecycle requirements.

Q: How does the reverse recovery time difference between ES1JLHRUG (35 ns) and HS1JL RVG (75 ns) affect circuit performance?

A: Both parts are classified as fast recovery rectifiers with reverse recovery time ≤500 ns for currents >200 mA. The 40 ns difference falls within the fast recovery classification and does not violate substitution criteria. Circuit impact depends on specific switching frequency and load conditions; however, both parts meet the same speed classification for general-purpose rectification applications.

Q: Are there packaging compatibility concerns when substituting between Tape & Reel and Cut Tape formats?

A: No. Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® are packaging and delivery formats only. They do not affect the electrical device itself or its mechanical fit within the DO-219AB footprint. Format selection is determined by manufacturing equipment and assembly process requirements, not circuit compatibility.

Q: Does the capacitance difference between ES1JLHRUG (8 pF) and HS1JL RVG (15 pF) create substitution limitations?

A: Both capacitance values are measured at identical conditions (4V, 1MHz) and fall within acceptable variation for fast recovery rectifier diodes. The 7 pF difference is within typical manufacturing tolerance ranges for this device category. Substitution is valid for general-purpose rectification applications.

Q: Which substitute part should be selected for new product designs?

A: HS1JL RVG is the appropriate selection for new product designs. This part carries Active product status, indicating ongoing manufacturer support and long-term availability. ES1JL, designated "Not For New Designs," is reserved for replacement and legacy system applications.

Q: Are all three parts (ES1JLHRUG, ES1JL, HS1JL RVG) qualified to AEC-Q101 automotive standards?

A: ES1JLHRUG and HS1JL RVG both carry explicit AEC-Q101 qualification. ES1JL specifications do not include AEC-Q101 designation in the provided data. For automotive applications requiring AEC-Q101 compliance, ES1JLHRUG or HS1JL RVG are the appropriate selections.
