Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DBL201G C1G are identified based on electrical and mechanical parameter equivalence. The substitution logic is structured as follows:

Direct Electrical Equivalence: Parts must match the core electrical specifications: 50 V peak reverse voltage, 2 A average rectified current, 1.15 V forward voltage drop at 2 A, and 2 µA reverse leakage current.

Mechanical Compatibility: Parts must utilize identical through-hole mounting and 4-DIP package configuration (0.300", 7.62mm) to ensure direct board-level compatibility without layout modifications.

Temperature and Compliance: Parts must operate within the -55°C to 150°C temperature range and maintain ROHS3 compliance and MSL 1 rating.

Key Parameters for Substitution:

• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.15 V @ 2 A
• Package / Case: 4-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Operating Temperature: -55°C ~ 150°C (TJ)

Engineering Selection Recommendations

DBL201G (Direct Equivalent)

The DBL201G is the primary substitute for the discontinued DBL201G C1G. This part maintains active product status and carries identical electrical and mechanical specifications. All core parameters—voltage rating, current capacity, forward voltage drop, reverse leakage, temperature range, and package configuration—are equivalent. The part is ROHS3 compliant with MSL 1 rating, ensuring compatibility with existing design requirements and supply chain standards.

DBL201GH (Parametric Equivalent with Automotive Qualification)

The DBL201GH provides parametric equivalence with the addition of automotive-grade qualification (AEC-Q101). This part meets all electrical and mechanical requirements of the original DBL201G C1G and is suitable for applications requiring automotive-level reliability and traceability. The automotive qualification does not alter the core electrical performance but indicates enhanced quality assurance and testing protocols. This part is appropriate for designs requiring automotive compliance or higher reliability standards.

Both substitute parts are manufactured by Taiwan Semiconductor Corporation and are currently in active production status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the DBL201G be used as a direct replacement for the DBL201G C1G?

A: Yes. The DBL201G provides direct electrical and mechanical equivalence. All specified parameters—50 V peak reverse voltage, 2 A average rectified current, 1.15 V forward voltage drop, operating temperature range, and 4-DIP through-hole package—are identical. The part is currently in active production status.

Q: What is the difference between DBL201G and DBL201GH?

A: Both parts are electrically and mechanically equivalent. The DBL201GH carries automotive-grade qualification (AEC-Q101) and is designated for automotive applications. For standard industrial applications, either part is suitable. For automotive or high-reliability applications, the DBL201GH is the appropriate selection.

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

A: No. All three parts utilize the identical 4-DIP (0.300", 7.62mm) through-hole package configuration. No board layout modifications or pin reassignment is required when substituting between these parts.

Q: Do these substitute parts maintain RoHS3 compliance?

A: Yes. Both DBL201G and DBL201GH are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the compliance profile of the original DBL201G C1G.

Q: What is the reverse leakage current specification difference noted in the parameter table?

A: The original DBL201G C1G specifies 2 µA reverse leakage at 5 V, while the substitute parts specify 2 µA at 50 V. Both measurements indicate equivalent leakage performance; the substitute parts provide the specification at the full rated voltage, which is the standard industry practice for bridge rectifier documentation.

Q: Are these parts suitable for high-temperature applications?

A: Yes. All three parts operate across the temperature range of -55°C to 150°C (TJ), supporting both low-temperature and high-temperature industrial applications.

Q: What inventory levels are available for these substitute parts?

A: The DBL201G has 1134 pieces in stock. The DBL201GH has 702 pieces in stock. Both parts are in active production and available for immediate procurement.
