Substitute Part Grouping Explanation

Substitute parts for the DBL151GHC1G are classified based on electrical parameter equivalence and product status. Substitution is valid when the following criteria are met:

Electrical Equivalence Criteria:

• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 A
• Operating Temperature Range: -55°C to 150°C (TJ)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: 4-DIP (0.300", 7.62mm)

Compliance Criteria:

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into two categories:

Direct Manufacturer Substitute: DBL151GH maintains all electrical and mechanical specifications with active product status.

Parametric Equivalent: DBL151G provides identical electrical performance and mechanical compatibility with active product status.

Engineering Selection Recommendations

DBL151GH (Direct Manufacturer Substitute):

The DBL151GH is the primary substitute for the discontinued DBL151GHC1G. This part is manufactured by Taiwan Semiconductor Corporation and maintains identical electrical specifications across all critical parameters: 50 V peak reverse voltage, 1.5 A average rectified current, and 1.1 V forward voltage at 1.5 A. The component shares the same 4-DIP through-hole package configuration and meets automotive-grade AEC-Q101 qualification requirements. Product status is active with 790 units in stock. RoHS3 compliance and MSL 1 rating are maintained. This part is suitable for direct replacement in existing designs without circuit modification.

DBL151G (Parametric Equivalent):

The DBL151G provides parametric equivalence to the DBL151GHC1G with identical electrical performance and mechanical compatibility. This part maintains the same 50 V voltage rating, 1.5 A current rating, and 1.1 V forward voltage specification. The 4-DIP through-hole package is identical. Product status is active with 1022 units in stock. RoHS3 compliance and MSL 1 rating are maintained. This part is suitable for applications requiring equivalent electrical performance and mechanical fit.

Both substitute parts are available from active inventory and support continued production and repair operations for applications previously using the DBL151GHC1G.

Frequently Asked Questions (FAQ)

Q: Can the DBL151GH be used as a direct replacement for the DBL151GHC1G?

A: Yes. The DBL151GH maintains identical electrical specifications (50 V, 1.5 A, 1.1 V forward voltage) and mechanical compatibility (4-DIP through-hole package). Both parts meet automotive-grade AEC-Q101 qualification and RoHS3 compliance requirements. No circuit modification is required.

Q: What is the difference between the DBL151GH and DBL151G?

A: Both parts provide identical electrical performance and mechanical compatibility with the DBL151GHC1G. The primary difference is product designation. Both are active products with equivalent availability and compliance status.

Q: Are the substitute parts compatible with the existing PCB layout?

A: Yes. Both substitute parts use the identical 4-DIP (0.300", 7.62mm) through-hole package configuration. PCB footprints and mounting hole spacing are compatible without modification.

Q: Do the substitute parts meet automotive qualification requirements?

A: The DBL151GH meets automotive-grade specifications with AEC-Q101 qualification. Automotive qualification status for the DBL151G is not specified in the provided data.

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

A: Both substitute parts operate across the temperature range of -55°C to 150°C (TJ), matching the DBL151GHC1G specification.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both DBL151GH and DBL151G are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the reverse leakage current specification for the substitute parts?

A: The DBL151GH and DBL151G specify 2 µA reverse leakage current at 50 V. The original DBL151GHC1G specifies 2 µA at 100 V, indicating the substitute parts maintain leakage performance within the 50 V operating range.
