S1GLHRUG Equivalent & Substitute Parts

Part Overview

The S1GLHRUG 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 automotive-grade qualification under AEC-Q101 standard.

Substitute parts become necessary when the primary part number experiences supply constraints, inventory limitations, or when design flexibility permits selection from qualified alternatives that maintain identical electrical and mechanical specifications. The S1GLHRUG serves as the reference part for identifying functionally equivalent components within the same product family.

Electrical Parameters (Must Match Exactly):

• 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
• Capacitance @ Vr, F: 9 pF @ 4V, 1MHz

Mechanical Parameters (Must Match Exactly):

• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Supplier Device Package: Sub SMA

Environmental & Compliance Parameters (Must Match Exactly):

• Operating Temperature - Junction: -55°C to 175°C
• Technology: Standard
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes for the S1GLHRUG.

Parameter Comparison

Engineering Selection Recommendations

The S1GL is a parametric equivalent to the S1GLHRUG, with all electrical, mechanical, and environmental specifications matching exactly. Both parts are manufactured by Taiwan Semiconductor Corporation and comply with ROHS3 and REACH requirements.

Selection Basis:

The S1GLHRUG carries Active product status, indicating it is the current production part recommended for new designs and ongoing applications. The S1GL is designated as Not For New Designs, reflecting its position as a legacy or transitional part within the product family.

For new circuit designs and production programs, the S1GLHRUG is the appropriate selection. The S1GL may be considered for existing designs or applications where supply continuity is required, provided that the Not For New Designs status does not conflict with program requirements or qualification standards.

Both parts maintain identical compliance certifications, including automotive-grade qualification under AEC-Q101, and are suitable for applications requiring 400 V, 1 A rectification in surface mount configurations.

Frequently Asked Questions (FAQ)

Q: Can S1GL be used as a direct replacement for S1GLHRUG in new designs?

A: S1GL is electrically and mechanically equivalent to S1GLHRUG. However, S1GL carries Not For New Designs status. For new circuit designs, S1GLHRUG is the recommended part number. S1GL may be used in existing designs where supply or inventory considerations apply.

Q: Are the electrical specifications identical between S1GLHRUG and S1GL?

A: Yes. Both parts share identical specifications for voltage rating (400 V), current rating (1 A), forward voltage (1.1 V @ 1 A), reverse recovery time (1.8 µs), reverse leakage current (5 µA @ 400 V), and junction capacitance (9 pF @ 4V, 1MHz).

Q: Do both parts use the same package?

A: Yes. Both S1GLHRUG and S1GL use the DO-219AB package in Sub SMA configuration for surface mount applications. PCB footprints and assembly processes are identical.

Q: What is the difference between S1GLHRUG and S1GL?

A: The primary difference is product status. S1GLHRUG is Active, while S1GL is Not For New Designs. All electrical, mechanical, and compliance parameters are identical. The difference reflects manufacturing and supply lifecycle positioning rather than technical capability.

Q: Are both parts automotive-qualified?

A: Yes. Both S1GLHRUG and S1GL carry automotive-grade classification and AEC-Q101 qualification, making them suitable for automotive and high-reliability applications.

Q: What is the operating temperature range for these parts?

A: Both parts operate across a junction temperature range of -55°C to 175°C, supporting applications in extreme thermal environments.

Q: Are these parts RoHS compliant?

A: Yes. Both S1GLHRUG and S1GL are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What is the moisture sensitivity level?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly.
