Substitute Part Grouping Explanation

Substitution of the DB154L-BP is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Voltage - Peak Reverse (Max): 400 V
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 A
• Diode Type: Single Phase
• Technology: Standard

Mechanical Specifications:

• Mounting Type: Through Hole
• Package / Case: 4-EDIP (0.321", 8.15mm)

Environmental Specifications:

• Operating Temperature Range: -55°C ~ 150°C (TJ)

A substitute part must match all electrical, mechanical, and environmental parameters listed above. Secondary parameters such as reverse leakage current, compliance certifications, and product status do not disqualify a part from substitution eligibility but may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

The DB154G manufactured by GeneSiC Semiconductor is a direct parametric equivalent to the DB154L-BP. Both components share identical electrical ratings (400V peak reverse voltage, 1.5A average rectified current, 1.1V forward voltage), identical mechanical specifications (4-EDIP through-hole package), and identical operating temperature range (-55°C to 150°C).

The DB154G offers the advantage of Active product status, indicating ongoing manufacturer support and availability. The DB154G also carries RoHS Compliance certification, which may be required for applications subject to environmental regulations. The DB154G exhibits lower reverse leakage current (5 µA versus 10 µA at 400V), representing improved performance characteristics.

Selection of DB154G over DB154L-BP is appropriate for replacement applications where component availability and regulatory compliance are considerations. Both parts are electrically and mechanically interchangeable within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can DB154G directly replace DB154L-BP in existing circuits?

A: Yes. The DB154G meets all electrical and mechanical specifications of the DB154L-BP. Both components are single-phase bridge rectifiers with 400V peak reverse voltage, 1.5A average rectified current, and identical 4-EDIP through-hole packaging. Direct substitution is supported without circuit modification.

Q: What is the significance of the "Not For New Designs" status on DB154L-BP?

A: This status indicates the DB154L-BP is obsolete or being discontinued by the manufacturer. New designs should not incorporate this part. For legacy system maintenance and repair, equivalent parts such as DB154G provide continued functionality with active manufacturer support.

Q: Are there differences in reverse leakage current between DB154L-BP and DB154G?

A: Yes. The DB154L-BP exhibits 10 µA reverse leakage at 400V, while DB154G exhibits 5 µA at the same voltage. This difference does not affect substitution eligibility but indicates improved performance characteristics in the DB154G. Both values remain within acceptable operating parameters for standard bridge rectifier applications.

Q: Does the RoHS Compliance status of DB154G affect compatibility?

A: No. RoHS Compliance is an environmental and regulatory certification that does not alter electrical or mechanical function. The DB154G's RoHS Compliance status makes it suitable for applications subject to environmental regulations, while maintaining full electrical equivalence to the DB154L-BP.

Q: Are the package dimensions identical between DB154L-BP and DB154G?

A: Yes. Both components use the 4-EDIP package with dimensions of 0.321" (8.15mm). Through-hole mounting specifications are identical, ensuring mechanical compatibility in PCB layouts designed for the DB154L-BP.
