Substitute Part Grouping Explanation

Substitute parts for the DBL103GHC1G are classified based on electrical and mechanical parameter matching within the bridge rectifier diode category. Substitution eligibility is determined by the following criteria:

Primary Matching Parameters:

• Voltage - Peak Reverse (Max): 200 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Current - Reverse Leakage @ Vr: 2 µA @ 200 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Mounting Type: Through Hole
• Package / Case: 4-DIP (0.300", 7.62mm)
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed maintain identical electrical performance characteristics and mechanical compatibility with the original DBL103GHC1G component.

Engineering Selection Recommendations

DBL103GH (Direct Substitute)

The DBL103GH is the primary direct substitute for the discontinued DBL103GHC1G. This part maintains active product status and is manufactured by Taiwan Semiconductor Corporation with identical electrical specifications and automotive-grade AEC-Q101 qualification. The DBL103GH is suitable for direct replacement in all applications where the DBL103GHC1G was originally specified. Current inventory availability is 900 pieces.

DBL103G (Parametric Equivalent)

The DBL103G provides parametric equivalence to the DBL103GHC1G with matching electrical performance and mechanical compatibility. This part is also manufactured by Taiwan Semiconductor Corporation and maintains active product status. The DBL103G is suitable for applications requiring identical electrical and thermal characteristics. Current inventory availability is 685 pieces.

Both substitute parts comply with ROHS3 requirements, maintain unlimited moisture sensitivity classification (MSL 1), and are unaffected by REACH regulations. Selection between DBL103GH and DBL103G should be based on availability and supply chain requirements, as both parts deliver equivalent performance in the 200 V, 1 A bridge rectifier application.
