DBLS103G C1G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBLS103G C1G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, designed for 200 V peak reverse voltage applications with 1 A average rectified current capacity. This component is classified as a standard technology bridge rectifier in surface mount packaging and maintains Active product status. Bridge rectifiers of this specification are essential in power supply circuits requiring full-wave rectification with compact form factors. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitution of the DBLS103G C1G is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

Diode Type: Single Phase
Technology: Standard
Voltage - Peak Reverse (Max): 200 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)

Mechanical Equivalence Criteria:

Mounting Type: Surface Mount
Package / Case: 4-SMD, Gull Wing

Compliance Equivalence Criteria:

RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part DF02S-E3/45 meets all electrical, mechanical, and compliance requirements within the specified parameter tolerances. Reverse leakage current variation (2 µA versus 5 µA @ 200 V) remains within acceptable operational limits for standard bridge rectifier applications and does not preclude functional equivalence.

Engineering Selection Recommendations

Both the DBLS103G C1G and DF02S-E3/45 maintain Active product status and full ROHS3 compliance with identical moisture sensitivity ratings. Selection between these components is based on availability, packaging format, and supply chain requirements rather than electrical or mechanical performance differences.

The DBLS103G C1G is supplied by Taiwan Semiconductor Corporation with 993 pieces in current inventory. The DF02S-E3/45 is supplied by Vishay General Semiconductor - Diodes Division with 3480 pieces in current inventory and is packaged in tube format.

Both components are suitable for direct substitution in 200 V, 1 A single-phase bridge rectifier applications requiring surface mount 4-SMD gull wing packaging. The marginal difference in reverse leakage current (2 µA versus 5 µA @ 200 V) does not impact functional equivalence for standard rectification circuits within the specified operating temperature range of -55°C to 150°C.

Frequently Asked Questions (FAQ)

Q: Can the DF02S-E3/45 be used as a direct replacement for the DBLS103G C1G?

A: Yes. Both components share identical electrical specifications for peak reverse voltage (200 V), average rectified current (1 A), forward voltage drop (1.1 V @ 1 A), and operating temperature range (-55°C to 150°C). Both use identical surface mount 4-SMD gull wing packaging and maintain ROHS3 compliance with MSL 1 rating.

Q: What is the significance of the reverse leakage current difference?

A: The DBLS103G C1G specifies 2 µA reverse leakage at 200 V, while the DF02S-E3/45 specifies 5 µA at the same conditions. This 3 µA difference is within acceptable tolerance for standard bridge rectifier applications and does not affect functional compatibility or circuit performance in typical power supply designs.

Q: Are the packaging formats identical?

A: Both components use 4-SMD gull wing surface mount packaging, ensuring mechanical compatibility with existing PCB layouts and assembly processes. The DBLS103G C1G is supplied in standard packaging, while the DF02S-E3/45 is supplied in tube format. This difference affects only handling and storage procedures, not component functionality or board-level integration.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DBLS103G C1G and DF02S-E3/45 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8541.10.0080. Both maintain MSL 1 (unlimited) moisture sensitivity rating.

Q: What determines whether a substitute part is acceptable?

A: Substitution is determined by equivalence across diode type, technology classification, peak reverse voltage, average rectified current, forward voltage characteristics, operating temperature range, surface mount mounting type, package configuration, and compliance certifications. All these parameters must match or fall within specified tolerances.
