S1BL RTG Equivalent & Substitute Parts

Part Overview

The S1BL RTG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package (DO-219AB). This component is classified as Active product status and is fully RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the original S1BL RTG reaches end-of-life status, experiences supply constraints, or when design requirements permit operation with alternative electrical characteristics within the same functional category. The S1BL RTG variant listed as "Not For New Designs" indicates potential availability or lifecycle considerations that may necessitate equivalent component selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the S1BL RTG is based on the following critical parameters that must remain constant or compatible:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Package / Case: DO-219AB (Sub SMA surface mount)
• Mounting Type: Surface Mount
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited)

Allowable Variation Parameters:

• Current - Average Rectified (Io): Equal or greater than 1 A
• Voltage - Forward (Vf): Equal or lower values acceptable
• Reverse Recovery Time (trr): Faster recovery times acceptable
• Current - Reverse Leakage: Lower values acceptable
• Operating Temperature Range: Equal or wider range acceptable

The S1BL variant from Taiwan Semiconductor Corporation is a parametric equivalent with identical electrical specifications and packaging. The VS-2EFH01HM3/I from Vishay General Semiconductor is classified as a similar manufacturer part with enhanced current rating (2 A vs. 1 A) and faster recovery characteristics, suitable for applications where the original 1 A specification is not a limiting constraint.

Parameter Comparison

Engineering Selection Recommendations

S1BL (Taiwan Semiconductor Corporation): This parametric equivalent maintains identical electrical specifications and packaging to the S1BL RTG. However, the "Not For New Designs" product status indicates this variant is in a mature or declining lifecycle phase. Selection of this substitute is appropriate only for replacement or maintenance applications where existing inventory or supply agreements exist. For new design implementations, this variant should not be selected.

VS-2EFH01HM3/I (Vishay General Semiconductor): This similar manufacturer part is classified as Active product status and carries AEC-Q101 automotive qualification. The VS-2EFH01HM3/I provides enhanced performance characteristics including doubled current rating (2 A vs. 1 A), significantly faster reverse recovery time (16 ns vs. 1.8 µs), and lower reverse leakage current (2 µA vs. 5 µA). The extended operating temperature range (-65 to 175°C vs. -55 to 175°C) provides additional thermal margin. All three components maintain DO-219AB packaging compatibility, RoHS3 compliance, and MSL 1 rating. The VS-2EFH01HM3/I is suitable for new designs where the enhanced electrical performance and automotive qualification are beneficial or required.

Frequently Asked Questions (FAQ)

Q: Can the S1BL RTG be directly replaced with the S1BL variant?

A: Yes, the S1BL variant is a parametric equivalent with identical voltage rating (100 V), current rating (1 A), forward voltage (1.1 V @ 1 A), reverse recovery time (1.8 µs), and package (DO-219AB). Direct pin-for-pin and functional substitution is supported. However, the "Not For New Designs" status should be considered for long-term supply planning.

Q: What are the key differences between the S1BL RTG and the VS-2EFH01HM3/I?

A: The primary differences are current rating (1 A vs. 2 A), reverse recovery time (1.8 µs vs. 16 ns), and reverse leakage current (5 µA vs. 2 µA). The VS-2EFH01HM3/I offers superior switching performance and lower leakage. Both maintain 100 V reverse voltage rating and DO-219AB packaging. The VS-2EFH01HM3/I includes AEC-Q101 automotive qualification.

Q: Is the VS-2EFH01HM3/I a drop-in replacement for the S1BL RTG?

A: The VS-2EFH01HM3/I is mechanically and electrically compatible in terms of package (DO-219AB) and voltage rating (100 V). The doubled current rating (2 A) and faster recovery characteristics (16 ns) represent performance enhancements rather than limitations. Functional substitution is supported for applications where the original 1 A specification does not represent a design constraint.

Q: Are all three parts RoHS3 compliant?

A: Yes, the S1BL RTG, S1BL variant, and VS-2EFH01HM3/I are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the "Not For New Designs" status on the S1BL variant?

A: This status indicates the component is in a mature lifecycle phase and may have limited future availability or support. While suitable for replacement and maintenance applications, new product designs should prioritize components with Active status, such as the S1BL RTG or VS-2EFH01HM3/I.

Q: Can the VS-2EFH01HM3/I be used in applications originally designed for 1 A operation?

A: Yes. The VS-2EFH01HM3/I 2 A rating exceeds the 1 A requirement, providing design margin. The faster recovery time and lower leakage current represent performance improvements. No circuit modifications are required for functional compatibility.

Q: What packaging formats are available for these parts?

A: The S1BL RTG is supplied in standard packaging. The S1BL variant is available in Cut Tape (CT) and Digi-Reel® formats. The VS-2EFH01HM3/I is supplied in Tape & Reel (TR) format. All maintain the DO-219AB (Sub SMA) physical package specification.
