DBLS101G C1G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBLS101G C1G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 50 V peak reverse voltage and 1 A average rectified current. This component is classified as Active product status and is RoHS3 compliant. The device is packaged in a 4-SMD, Gull Wing surface mount configuration suitable for automated assembly processes.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design flexibility is required across multiple suppliers. The DBLS101G C1G maintains parametric equivalence with several alternative bridge rectifier models that share identical electrical ratings and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the DBLS101G C1G is determined by strict parametric matching across the following criteria:

Primary Substitution Criteria:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Operating Temperature Range: -55°C to 150°C (TJ)
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed maintain these electrical and mechanical parameters. Variations in Current - Reverse Leakage @ Vr do not disqualify substitution, as this parameter remains within acceptable operational limits for bridge rectifier applications. Differences in product status (Active versus Obsolete) and packaging format (Tube) are noted for procurement planning but do not affect electrical compatibility.

Engineering Selection Recommendations

Primary Selection (Active Status):

The DBLS101G C1G and DF005S-E3/45 are both classified as Active products. The DF005S-E3/45, manufactured by Vishay General Semiconductor - Diodes Division, is the preferred substitute when long-term availability and continued manufacturer support are required. This part maintains all electrical specifications and is available in higher inventory quantities (5644 Pcs).

Secondary Selection (Obsolete Status):

The DB101S-G (Comchip Technology) and DF005S-G (Comchip Technology) are classified as Obsolete. These parts maintain full parametric equivalence but carry obsolescence risk. Selection of obsolete parts is appropriate only when existing inventory is confirmed available and long-term supply is not a design requirement.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original DBLS101G C1G. Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) is consistent across all options, eliminating moisture-related handling constraints.

Reverse Leakage Variation:

The DBLS101G C1G exhibits the lowest reverse leakage specification at 2 µA @ 50 V. Substitute parts show higher reverse leakage values (5 µA to 10 µA @ 50 V). This variation does not affect substitution eligibility, as all values remain within acceptable operational parameters for standard bridge rectifier applications.

Frequently Asked Questions (FAQ)

Q: Can the DB101S-G replace the DBLS101G C1G in new designs?

A: The DB101S-G is electrically and mechanically equivalent to the DBLS101G C1G. However, DB101S-G carries Obsolete product status. New designs should prioritize Active status parts such as the DBLS101G C1G or DF005S-E3/45 to ensure long-term supply continuity.

Q: What is the significance of the Current - Reverse Leakage difference between parts?

A: The DBLS101G C1G specifies 2 µA @ 50 V reverse leakage, while substitute parts range from 5 µA to 10 µA @ 50 V. All values remain within acceptable limits for bridge rectifier operation. The difference does not affect circuit functionality or reliability in standard applications.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All listed substitute parts share identical mechanical specifications: 4-SMD, Gull Wing package configuration with Surface Mount mounting type. PCB footprints and assembly processes require no modification.

Q: Which substitute part offers the best long-term availability?

A: The DF005S-E3/45 (Vishay General Semiconductor - Diodes Division) is classified as Active with 5644 Pcs in stock inventory. This part is the recommended choice for applications requiring extended supply assurance.

Q: Do substitute parts require different handling or storage procedures?

A: No. All substitute parts share identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), eliminating the need for modified storage or handling protocols.

Q: Can I use DF005S-E3/45 as a direct replacement in existing assemblies?

A: Yes. The DF005S-E3/45 maintains full parametric equivalence with the DBLS101G C1G across all electrical and mechanical specifications. No circuit modifications or re-qualification is required.
