S1BLHRUG Equivalent & Substitute Parts

Part Overview

The S1BLHRUG 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. 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 locations. The S1BL represents a parametrically equivalent alternative with identical electrical specifications but carries a Not For New Designs product status, making it suitable for legacy system support and maintenance applications only.

Substitute Part Grouping Explanation

Substitution eligibility for the S1BLHRUG is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 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 @ 100 V
• Capacitance @ Vr, F: 9 pF @ 4V, 1MHz
• Operating Temperature - Junction: -55°C to 175°C
• Package / Case: DO-219AB
• Mounting Type: Surface Mount

The S1BL part number meets all electrical parameter requirements and maintains identical package specifications. This part is classified as a parametric equivalent and serves as a direct functional substitute for the S1BLHRUG in applications where product status constraints do not prohibit its use.

Engineering Selection Recommendations

For New Designs: The S1BLHRUG is the appropriate selection. This part carries Active product status and maintains full AEC-Q101 automotive qualification, ensuring long-term availability and compliance with current design standards.

For Legacy System Support and Maintenance: The S1BL substitute part is electrically and mechanically equivalent to the S1BLHRUG and carries identical electrical specifications, package configuration, and compliance certifications (ROHS3, REACH Unaffected). However, the S1BL is designated as Not For New Designs, restricting its use to replacement and repair applications for existing systems.

Compliance Considerations: Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical moisture sensitivity levels. The S1BLHRUG carries explicit AEC-Q101 automotive qualification; the S1BL specification does not reference this qualification status in the provided data.

Frequently Asked Questions (FAQ)

Q: Can the S1BL be used as a direct replacement for the S1BLHRUG in new product designs?

A: No. The S1BL carries a Not For New Designs product status designation. New designs must use the S1BLHRUG, which maintains Active status and ensures long-term supply chain stability.

Q: Are the electrical characteristics identical between S1BLHRUG and S1BL?

A: Yes. Both parts share identical electrical specifications: 100 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 100 V.

Q: Do both parts use the same package and mounting configuration?

A: Yes. Both the S1BLHRUG and S1BL use the DO-219AB package in Sub SMA form factor with surface mount mounting type. PCB layout and assembly processes are identical.

Q: What is the difference in inventory availability between these parts?

A: The S1BLHRUG has 979 pieces in stock. The S1BL has 15,200 pieces in stock. Inventory levels are subject to change and should be verified at time of procurement.

Q: Are there compliance or certification differences between the two parts?

A: Both parts are ROHS3 compliant and REACH Unaffected. The S1BLHRUG carries explicit AEC-Q101 automotive qualification. The S1BL specification data does not reference AEC-Q101 qualification status.

Q: Can the S1BL be used in automotive applications?

A: The S1BL electrical specifications are equivalent to an AEC-Q101 qualified part. However, the S1BL is designated Not For New Designs. Automotive applications requiring new designs must use the S1BLHRUG. Existing automotive systems using the S1BL may continue with this part for maintenance purposes.

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

A: Both the S1BLHRUG and S1BL operate across a junction temperature range of -55°C to 175°C, supporting industrial and automotive temperature environments.
