DBLS101GHRDG Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBLS101GHRDG is a single-phase bridge rectifier diode manufactured by Taiwan Semiconductor Corporation. This component is classified as a standard bridge rectifier rated for 50 V peak reverse voltage and 1 A average rectified current, packaged in a 4-SMD Gull Wing surface mount configuration. The part maintains active product status and carries AEC-Q101 automotive qualification with ROHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter range.

Substitute Part Grouping Explanation

Substitution of the DBLS101GHRDG is determined by strict equivalence across the following critical parameters:

Electrical Equivalence 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)

Mechanical Equivalence Criteria:

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

Compliance Criteria:

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

All substitute parts listed maintain these parameters within the specified tolerances. Reverse leakage current variation does not disqualify substitution when all primary electrical and mechanical parameters remain equivalent.

Engineering Selection Recommendations

All listed substitute parts maintain electrical and mechanical equivalence to the DBLS101GHRDG across the critical parameters that define bridge rectifier functionality: peak reverse voltage, average rectified current, forward voltage drop, and operating temperature range.

DF005S-E3/77 and DF005SA-E3/77 are manufactured by Vishay General Semiconductor - Diodes Division and carry ROHS3 compliance with MSL 1 rating. Both parts are supplied in Tape & Reel packaging and maintain identical electrical specifications to the main part.

DF005S1 is manufactured by Fairchild Semiconductor and supplied in Bulk packaging. This part maintains all critical electrical parameters and surface mount configuration. RoHS and MSL specifications are not provided in the available data.

All substitute parts carry active product status, confirming ongoing availability and manufacturing support. Selection among these alternatives is determined by packaging requirements, inventory availability, and supplier preference rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can DF005S-E3/77 replace DBLS101GHRDG in automotive applications?

A: Yes. Both parts maintain identical electrical specifications (50 V peak reverse, 1 A average rectified current, 1.1 V forward voltage), identical operating temperature range (-55°C to 150°C), and identical surface mount 4-SMD Gull Wing packaging. DF005S-E3/77 carries ROHS3 compliance and MSL 1 rating equivalent to the main part.

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

A: The primary difference is packaging format. DF005S1 is supplied in Bulk packaging, while DF005S-E3/77 is supplied in Tape & Reel (TR) format. Electrical specifications and mechanical package configuration are identical. RoHS and MSL data are not provided for DF005S1.

Q: Are there differences in reverse leakage current between the main part and substitutes?

A: Yes. DBLS101GHRDG specifies 2 µA reverse leakage at 50 V, while DF005S-E3/77 and DF005SA-E3/77 specify 5 µA, and DF005S1 specifies 3 µA. All values remain within acceptable operating parameters for standard bridge rectifier applications. This variation does not affect substitution eligibility.

Q: Can DF005SA-E3/77 be used as a direct replacement for DBLS101GHRDG?

A: Yes. DF005SA-E3/77 maintains all critical electrical parameters, operating temperature range, surface mount configuration, and compliance certifications (ROHS3, MSL 1) required for direct substitution.

Q: What packaging considerations apply when selecting a substitute?

A: DBLS101GHRDG is supplied in standard packaging (not specified as Tape & Reel or Bulk). DF005S-E3/77 and DF005SA-E3/77 are supplied in Tape & Reel format, suitable for automated assembly. DF005S1 is supplied in Bulk format. Packaging selection depends on production volume and assembly process requirements.

Q: Are all substitute parts currently in active production?

A: Yes. All substitute parts maintain active product status, confirming current manufacturing availability and ongoing supplier support.
