S1GLHRTG Equivalent & Substitute Parts

Part Overview

The S1GLHRTG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 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.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or when design flexibility is required across manufacturing batches. The S1GLHRTG maintains full electrical and mechanical compatibility with identified substitute part numbers that share identical electrical specifications and package configurations.

Substitute Part Grouping Explanation

Substitution eligibility for the S1GLHRTG is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Reverse Recovery Time (trr): 1.8 µs
• Current - Reverse Leakage @ Vr: 5 µA @ 400 V
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Technology: Standard

The S1GL part number is identified as a parametric equivalent to the S1GLHRTG. Both components share identical electrical ratings, recovery characteristics, leakage specifications, and package configuration. The S1GL is supplied in Tape & Reel packaging format, whereas the S1GLHRTG is supplied in standard packaging. Both components are manufactured by Taiwan Semiconductor Corporation and comply with ROHS3 and AEC-Q101 requirements.

Engineering Selection Recommendations

S1GLHRTG (Primary Selection)

The S1GLHRTG is the recommended selection for new designs. This part maintains Active product status, indicating full manufacturer support and continued availability. The component carries AEC-Q101 automotive qualification and ROHS3 compliance, meeting stringent reliability and environmental standards. Standard packaging format provides flexibility for both prototype and production environments.

S1GL (Substitute Selection)

The S1GL is electrically and mechanically equivalent to the S1GLHRTG across all critical parameters. However, this part is designated as Not For New Designs, indicating the manufacturer has transitioned this part number to legacy status. The S1GL is supplied exclusively in Tape & Reel packaging format, which is suitable for high-volume automated assembly operations but may present handling constraints for lower-volume or prototype applications.

Selection of S1GL is appropriate when:

• Existing inventory of S1GL components is available and must be utilized
• High-volume production runs justify Tape & Reel packaging logistics
• Design flexibility permits use of legacy part numbers
• Supply chain constraints on S1GLHRTG necessitate alternative sourcing

Both parts maintain identical electrical performance, thermal operating range, and regulatory compliance. Substitution between these part numbers does not require circuit redesign or performance re-qualification.

Frequently Asked Questions (FAQ)

Q: Are S1GLHRTG and S1GL electrically interchangeable?

A: Yes. Both components share identical electrical specifications across all critical parameters: 400 V reverse voltage rating, 1 A average rectified current, 1.1 V forward voltage drop at 1 A, 1.8 µs reverse recovery time, and 5 µA reverse leakage current at 400 V. No circuit modifications are required for substitution.
