Key Parameters

Substitute Part Grouping Explanation

Substitution of the DB101SP-HF is determined by electrical and mechanical parameter equivalence. The critical parameters for substitution are:

• Voltage Rating: Peak reverse voltage of 50 V
• Current Rating: Average rectified current of 1 A
• Forward Voltage Characteristic: Maximum forward voltage of 1.1 V at 1 A
• Reverse Leakage: Maximum reverse leakage current of 10 µA at 50 V
• Diode Configuration: Single-phase bridge rectifier topology
• Package Type: 4-SMD, Gull Wing surface mount configuration (DBS package)
• Operating Temperature Range: -55°C to 150°C

The primary substitute, DB101S-HF, maintains identical electrical specifications and package configuration while offering active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DB101S-HF is the primary substitute for the obsolete DB101SP-HF. Both components are manufactured by Comchip Technology and share identical electrical and mechanical specifications. The DB101S-HF maintains active product status, ensuring long-term availability and supply chain continuity. Both parts comply with ECCN EAR99 and HTSUS 8541.10.0080 classifications.
