S1GLHRVG Equivalent & Substitute Parts

Part Overview

The S1GLHRVG 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.

The S1GLHRVG may require substitution due to inventory constraints, supply chain discontinuation of specific packaging configurations, or application-specific requirements for alternative part variants within the same electrical and mechanical specification family.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S1GLHRVG is permissible with parts that maintain identical electrical characteristics across all critical parameters: 400 V DC reverse voltage rating, 1 A average rectified current, 1.1 V maximum forward voltage at 1 A, 1.8 µs reverse recovery time, 5 µA reverse leakage current at 400 V, and 9 pF capacitance at 4 V and 1 MHz. The package type must remain DO-219AB Sub SMA surface mount configuration. Operating temperature range, RoHS compliance status, and AEC-Q101 qualification must be maintained.

Substitution logic is based on the following key 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

Parameter Comparison

Engineering Selection Recommendations

The S1GL is a parametric equivalent to the S1GLHRVG with identical electrical and mechanical specifications. Both parts are manufactured by Taiwan Semiconductor Corporation and share the same base product number S1G.

The primary distinction between these parts is product status: S1GLHRVG is designated as Active, while S1GL is designated as Not For New Designs. This status difference reflects supply chain positioning rather than technical capability.

For new design implementations, S1GLHRVG is the appropriate selection due to its Active product status, which ensures long-term availability and manufacturer support. The S1GL substitute is suitable for legacy system maintenance, repair operations, or applications where existing inventory must be utilized, provided that the Not For New Designs status aligns with project requirements.

Both parts maintain AEC-Q101 automotive qualification and ROHS3 compliance. The difference in packaging designation (S1GLHRVG supplied in standard packaging versus S1GL supplied in Tape & Reel configuration) reflects distribution format rather than component performance.

Frequently Asked Questions (FAQ)

Q: Can S1GL be used as a direct replacement for S1GLHRVG in production assemblies?

A: S1GL is electrically and mechanically equivalent to S1GLHRVG across all specified parameters. However, S1GL carries a Not For New Designs product status designation. Direct substitution is technically feasible but should be evaluated against project lifecycle requirements and supply chain strategy.

Q: What is the significance of the packaging difference between S1GLHRVG and S1GL?

A: S1GLHRVG is supplied in standard packaging, while S1GL is supplied in Tape & Reel (TR) format. Both configurations use the identical DO-219AB Sub SMA package type. The packaging designation reflects distribution and handling format for manufacturing operations rather than component specifications or performance characteristics.

Q: Are both parts qualified to the same automotive standard?

A: Both S1GLHRVG and S1GL carry AEC-Q101 automotive qualification. This certification applies to both parts regardless of their product status designation.

Q: What inventory considerations apply to these substitute parts?

A: S1GLHRVG has 802 pieces in stock. S1GL has 30,400 pieces in stock. Inventory availability may influence substitution decisions for high-volume requirements or extended lead-time mitigation strategies.

Q: Do both parts comply with environmental and regulatory requirements?

A: Both S1GLHRVG and S1GL are ROHS3 compliant and REACH unaffected. Both carry identical environmental compliance status and are suitable for applications requiring these certifications.

Q: What does the Not For New Designs status mean for S1GL?

A: Not For New Designs indicates that the manufacturer recommends using S1GLHRVG for new product development. S1GL remains available for existing applications and legacy system support but is not recommended for designs entering production for the first time.
