Substitute Part Grouping Explanation

Substitute parts for the DBL201GHC1G are classified based on electrical and mechanical parameter equivalence. All substitute parts must satisfy the following criteria to ensure direct interchangeability:

Mandatory Equivalence Parameters:

• Diode Type: Single Phase
• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.15 V @ 2 A
• Operating Temperature Range: -55°C to 150°C (TJ)
• Mounting Type: Through Hole
• Package / Case: 4-DIP (0.300", 7.62mm)
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

Substitute Classification:

Direct Manufacturer Equivalent: DBL201GH meets all mandatory equivalence parameters. This part is manufactured by Taiwan Semiconductor Corporation and maintains identical electrical ratings and package specifications. Current - Reverse Leakage @ Vr is specified at 50 V (compared to 5 V in the main part), representing a more stringent measurement condition.

Parametric Equivalent: DBL201G meets all mandatory equivalence parameters. This part is manufactured by Taiwan Semiconductor Corporation and maintains identical electrical ratings and package specifications. Current - Reverse Leakage @ Vr is specified at 50 V. Grade and Qualification parameters are not specified in the provided data but do not contradict equivalence based on available parameters.

Engineering Selection Recommendations

DBL201GH (Direct Manufacturer Equivalent):

The DBL201GH is the primary substitute for the discontinued DBL201GHC1G. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain identical electrical specifications across all critical parameters: 50 V peak reverse voltage, 2 A average rectified current, 1.15 V forward voltage drop at 2 A, and -55°C to 150°C operating temperature range. The DBL201GH is currently in active production status with 702 units in stock. This part carries automotive-grade qualification (AEC-Q101) and ROHS3 compliance, meeting the same regulatory and quality standards as the main part. The 4-DIP through-hole package is identical, ensuring direct mechanical compatibility in existing PCB layouts.

DBL201G (Parametric Equivalent):

The DBL201G provides an alternative substitute option with identical electrical performance specifications. This part maintains the same 50 V / 2 A rating, 1.15 V forward voltage characteristic, and -55°C to 150°C operating temperature range. The DBL201G is in active production with 1,134 units in stock, offering superior availability. The 4-DIP through-hole package configuration is identical to the main part. ROHS3 compliance and EAR99 export classification are maintained. Grade and Qualification parameters are not specified in available documentation for this part number variant.

Selection Basis:

Both substitute parts satisfy all mandatory equivalence parameters for direct interchangeability with the DBL201GHC1G. Selection between DBL201GH and DBL201G should be based on inventory availability, lead time requirements, and internal qualification status within the design organization. The DBL201GH maintains explicit automotive-grade and AEC-Q101 documentation alignment with the original part specification.

Frequently Asked Questions (FAQ)

Q: Can DBL201GH be used as a direct replacement for DBL201GHC1G in existing designs?

A: Yes. The DBL201GH maintains identical electrical specifications (50 V peak reverse voltage, 2 A average rectified current, 1.15 V forward voltage at 2 A) and identical package configuration (4-DIP through-hole, 0.300" / 7.62mm). Both parts are manufactured by Taiwan Semiconductor Corporation and carry automotive-grade AEC-Q101 qualification. Pin-to-pin compatibility is maintained.

Q: What is the difference between DBL201GH and DBL201G?

A: Both parts meet identical electrical specifications for voltage, current, and temperature range. The primary difference is in reverse leakage current measurement conditions: DBL201GH specifies 2 µA @ 50 V, while DBL201G also specifies 2 µA @ 50 V. DBL201G has higher inventory availability (1,134 units versus 702 units). Grade and Qualification parameters are explicitly documented for DBL201GH but not provided for DBL201G in available data.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both DBL201GH and DBL201G are ROHS3 compliant, matching the compliance status of the original DBL201GHC1G part.

Q: Can these parts be used in automotive applications?

A: Yes. Both substitute parts carry automotive-grade classification and AEC-Q101 qualification, identical to the original part. These certifications confirm suitability for automotive-grade applications.

Q: Is the 4-DIP package identical across all three part numbers?

A: Yes. The DBL201GHC1G, DBL201GH, and DBL201G all use the 4-DIP package with 0.300" (7.62mm) lead spacing. PCB footprints and through-hole mounting requirements are identical.

Q: What is the operating temperature range for substitute parts?

A: Both substitute parts operate across -55°C to 150°C (TJ), identical to the original DBL201GHC1G specification.
