ES1BL RUG Equivalent & Substitute Parts

Part Overview

The ES1BL RUG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100V DC reverse voltage and 1A average rectified current in a Sub SMA surface mount package. This component is classified as Active product status and is RoHS3 compliant with AEC-Q101 automotive qualification available in related variants.

Substitute parts are necessary when the primary part number becomes unavailable, when design requirements mandate specific certifications such as automotive qualification, or when application parameters allow for alternative electrical characteristics within acceptable operating ranges.

Substitute Part Grouping Explanation

Substitution eligibility for the ES1BL RUG is determined by the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): Must equal 100V
Package / Case: Must be DO-219AB or Sub SMA equivalent
Mounting Type: Must be Surface Mount
Current - Average Rectified (Io): Must support minimum 1A operation

Secondary Compatibility Factors:

Reverse Recovery Time (trr): Lower values indicate improved performance
Voltage - Forward (Vf): Variations within 30mV are acceptable for general-purpose applications
Reverse Leakage Current: Lower values indicate superior performance
Operating Temperature Range: Must encompass application requirements
RoHS and REACH Compliance: Must maintain regulatory compliance

Parts are grouped into two categories: Parametric Equivalents (identical electrical specifications from the same manufacturer) and Similar Parts (alternative manufacturers with comparable but not identical electrical characteristics).

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

ES1BL and ES1BLH are parametric equivalents of ES1BL RUG with identical electrical specifications. Both parts maintain 100V reverse voltage rating, 1A average rectified current, and 35ns reverse recovery time. ES1BLH includes AEC-Q101 automotive qualification and should be selected for applications requiring automotive-grade components. ES1BL is marked as Not For New Designs and should be used only for legacy system maintenance or when existing inventory is available.

For Enhanced Performance (Similar Parts):

ES07B-GS18 (Vishay) provides 1.2A current rating with improved 25ns reverse recovery time while maintaining 100V voltage rating and Active product status. This part is suitable for applications requiring higher current capacity or faster switching performance.

ES07B-GS08 (Vishay) is rated for 500mA and includes AEC-Q101 qualification. This part is appropriate only for applications with reduced current requirements below 1A.

VS-2EFH01HM3/I (Vishay FRED Pt® series) offers the highest performance with 2A current rating, 16ns reverse recovery time, and extended temperature range (-65 to 175°C). This part includes AEC-Q101 qualification and Active product status. Selection is appropriate for high-performance applications or systems requiring extended temperature operation.

Product Status Consideration:

ES1BL RUG maintains Active status, indicating continued manufacturer support and availability. Substitute parts ES1BL and ES1BLH are marked Not For New Designs; these should be reserved for replacement applications only. All Vishay alternatives (ES07B-GS08, ES07B-GS18, VS-2EFH01HM3/I) maintain Active status and are suitable for new designs.

Frequently Asked Questions (FAQ)

Q: Can ES1BL RUG be directly replaced with ES1BL or ES1BLH?

A: ES1BL and ES1BLH are parametric equivalents with identical electrical specifications (100V, 1A, 35ns trr). Both are pin-compatible in DO-219AB packages. ES1BLH includes AEC-Q101 automotive qualification; ES1BL does not. Both are marked Not For New Designs. Direct replacement is electrically valid but should be limited to legacy applications.

Q: What is the difference between ES07B-GS18 and ES1BL RUG?

A: Both parts are rated 100V and support 1A+ current in DO-219AB packages. ES07B-GS18 offers improved performance with 25ns reverse recovery time (versus 35ns), 1.2A current rating, and Active product status. Forward voltage is slightly higher at 980mV versus 950mV. ES07B-GS18 is manufactured by Vishay and is suitable for new designs.

Q: Is VS-2EFH01HM3/I a suitable substitute for ES1BL RUG?

A: VS-2EFH01HM3/I is a similar part with 100V rating and DO-219AB package compatibility. It provides superior performance with 2A current rating, 16ns reverse recovery time, and extended temperature range (-65 to 175°C). Forward voltage is equivalent at 950mV. This part is suitable for applications requiring higher current capacity or improved switching speed. AEC-Q101 qualification is included.

Q: Why do some substitute parts have lower current ratings than ES1BL RUG?

A: ES07B-GS08 is rated for 500mA, which is below the 1A requirement of ES1BL RUG. This part should not be selected for applications requiring 1A operation. It is included in the substitute list for reference only and is appropriate only for reduced-current applications.

Q: What packaging formats are available for these substitute parts?

A: All listed parts use DO-219AB surface mount package. ES1BL RUG is supplied in Tape & Reel (TR) format. ES07B-GS08 is available in Cut Tape (CT) & Digi-Reel® format. ES07B-GS18 and VS-2EFH01HM3/I are supplied in Tape & Reel (TR) format. Packaging format does not affect electrical compatibility but may affect procurement and assembly processes.

Q: Are all substitute parts RoHS3 compliant?

A: All listed parts, including ES1BL RUG and all substitutes, are ROHS3 compliant and REACH unaffected. Regulatory compliance is maintained across all alternatives.

Q: Which substitute part should be selected for automotive applications?

A: For automotive applications, ES1BLH, ES07B-GS08, and VS-2EFH01HM3/I include AEC-Q101 qualification. ES1BLH is the direct parametric equivalent with automotive qualification. VS-2EFH01HM3/I offers enhanced performance with automotive qualification and extended temperature range. Selection depends on specific current and temperature requirements.
