DBLS101G RDG Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBLS101G RDG is a single-phase bridge rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V peak reverse voltage and 1 A average rectified current. This component is classified as an active product and is RoHS3 compliant. Bridge rectifier diodes are essential in power supply circuits for converting alternating current to direct current. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across different manufacturers and packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DBLS101G RDG are qualified based on the following criteria:

Electrical Parameters (Critical for Substitution):

• 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 ~ 150°C (TJ)
• Diode Type: Single Phase
• Technology: Standard

Mechanical Parameters (Required for Compatibility):

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

Compliance Parameters:

• RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional equivalence in circuit applications. Variations in reverse leakage current (within acceptable ranges) and packaging format (Tape & Reel versus Bulk) do not affect electrical substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (DF005S-E3/77, DF005S1, and DF005SA-E3/77) are electrically and mechanically equivalent to the DBLS101G RDG for bridge rectifier applications requiring 50 V, 1 A single-phase rectification.

DF005S-E3/77 and DF005SA-E3/77 are manufactured by Vishay General Semiconductor - Diodes Division and are supplied in Tape & Reel packaging format. Both parts are RoHS3 compliant, REACH unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity rating. These parts are suitable for automated assembly processes.

DF005S1 is manufactured by Fairchild Semiconductor and is supplied in Bulk packaging format. This part maintains the same electrical specifications and 4-SMD, Gull Wing package configuration. Bulk packaging is suitable for manual assembly or lower-volume applications.

All substitute parts maintain active product status and are available in significant inventory quantities. Selection between substitutes should be based on packaging format requirements (Tape & Reel for automated assembly, Bulk for manual assembly) and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can DF005S-E3/77 replace DBLS101G RDG in a circuit design?

A: Yes. Both parts share identical electrical specifications: 50 V peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A, and -55°C to 150°C operating temperature range. Both use 4-SMD, Gull Wing surface mount packaging. The primary difference is the packaging format (Tape & Reel versus unspecified) and manufacturer.

Q: What is the difference between DF005S1 and DF005S-E3/77?

A: Both parts are electrically equivalent with identical voltage and current ratings. The primary differences are manufacturer (Fairchild Semiconductor versus Vishay), packaging format (Bulk versus Tape & Reel), and reverse leakage current specification (3 µA versus 5 µA at 50 V). All differences fall within acceptable substitution parameters.

Q: Are all substitute parts RoHS3 compliant?

A: DF005S-E3/77 and DF005SA-E3/77 are explicitly RoHS3 compliant. DF005S1 does not specify RoHS status in the provided data. Compliance verification is required if RoHS3 certification is a design requirement.

Q: What packaging format should I select for automated assembly?

A: DF005S-E3/77 and DF005SA-E3/77 are supplied in Tape & Reel format, which is standard for automated pick-and-place assembly. DF005S1 is supplied in Bulk format, which is suitable for manual assembly or lower-volume applications.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, all substitute parts use identical 4-SMD, Gull Wing surface mount packaging and can be placed on the same PCB footprint without modification.

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

A: The DBLS101G RDG specifies 2 µA reverse leakage at 50 V, while DF005S-E3/77 and DF005SA-E3/77 specify 5 µA, and DF005S1 specifies 3 µA. These variations are within acceptable ranges for standard bridge rectifier applications and do not affect functional substitution.

Q: Are moisture sensitivity levels equivalent across all parts?

A: DF005S-E3/77, DF005SA-E3/77, and DBLS101G RDG all specify MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. DF005S1 does not specify MSL in the provided data.
