DBL209G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBL209G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 1.4 kV peak reverse voltage and 2 A average rectified current. This component is designed for through-hole mounting in 4-DIP package configuration and operates across the temperature range of -55°C to 150°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Bridge rectifiers serve as essential components in AC-to-DC conversion circuits. Identifying equivalent and substitute parts is necessary when managing inventory constraints, addressing supply chain disruptions, or accommodating design revisions that require alternative qualified sources while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the DBL209G is determined by strict parametric matching across the following critical criteria:

Electrical Parameters (Must Match Exactly):

• Voltage - Peak Reverse (Max): 1.4 kV
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 2 A
• Current - Reverse Leakage @ Vr: 2 µA @ 1400 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Mechanical Parameters (Must Match Exactly):

• Diode Type: Single Phase
• Mounting Type: Through Hole
• Package / Case: 4-DIP (0.300", 7.62mm)
• Technology: Standard

Compliance Parameters:

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

The DBL209GH qualifies as a parametric equivalent substitute because it satisfies all electrical, mechanical, and compliance requirements specified above. The presence of automotive-grade qualification (AEC-Q101) in the substitute part represents an enhanced specification that does not compromise compatibility with standard applications.

Selection of this part number is suitable when standard-grade qualification is sufficient and cost optimization is a primary consideration.

DBL209GH Selection Criteria: The DBL209GH provides identical electrical and mechanical performance to the DBL209G while incorporating automotive-grade qualification (AEC-Q101). This substitute part is appropriate for applications requiring enhanced reliability assurance, automotive-sector compliance, or environments with more stringent quality requirements. The DBL209GH maintains superior inventory availability (6032 pcs in stock) and identical ROHS3 compliance and MSL rating.

Both parts are manufactured by Taiwan Semiconductor Corporation and share the same base product number (DBL209), ensuring design continuity and interchangeability within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can DBL209GH be used as a direct replacement for DBL209G in existing designs?

A: Yes. The DBL209GH is a parametric equivalent substitute that matches all critical electrical specifications (1.4 kV peak reverse voltage, 2 A average rectified current, 1.3 V forward voltage, 2 µA reverse leakage) and mechanical requirements (4-DIP through-hole package, -55°C to 150°C operating range). No circuit modifications are required.

Q: What is the difference between DBL209G and DBL209GH?

A: The primary difference is qualification level. The DBL209GH carries AEC-Q101 automotive-grade qualification, while the DBL209G is standard-grade. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical performance, forward voltage characteristics, reverse leakage specifications, and package configuration.

Q: Are there any package or pinout differences between these parts?

A: No. Both the DBL209G and DBL209GH use the identical 4-DIP (0.300", 7.62mm) package configuration with through-hole mounting. Pinout and physical dimensions are identical, enabling direct board-level substitution without layout modifications.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the DBL209G and DBL209GH are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level. Both parts are REACH unaffected and carry the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For standard industrial applications, the DBL209G provides cost-effective performance. For automotive applications or designs requiring enhanced reliability documentation, the DBL209GH with AEC-Q101 qualification is the appropriate choice. Both parts maintain Active product status and adequate inventory levels.

Q: Are there any temperature or thermal performance differences?

A: No. Both parts operate across the identical temperature range of -55°C to 150°C (TJ) with matching thermal characteristics and reverse leakage specifications at rated voltage conditions.
