Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DBI20-16B are identified based on strict electrical and mechanical parameter matching. The substitution criteria are established by the following key parameters:

• Diode Type: Three Phase configuration
• Voltage - Peak Reverse (Max): 1.6 kV
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 20 A
• Current - Reverse Leakage @ Vr: 10 µA @ 1600 V
• Operating Temperature Range: -50°C ~ 150°C (TJ)
• Mounting Type: Through Hole
• Package / Case: 5-SIP
• Supplier Device Package: DBI-B

All substitute parts must match these parameters exactly to ensure functional and mechanical compatibility within the target application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the main part DBI20-16B and its substitute maintain active product status with full electrical and mechanical parameter alignment. The substitute part is ROHS3 compliant with REACH information available upon request, providing enhanced regulatory documentation compared to the main part listing. Selection between these parts should be based on inventory availability and supply chain requirements, as both components satisfy identical electrical specifications and package requirements for three-phase bridge rectifier applications operating at 1.6 kV with 3 A average rectified current.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the DBI20-16B?

A: A valid substitute must match all electrical parameters including peak reverse voltage (1.6 kV), average rectified current (3 A), forward voltage (1.3 V @ 20 A), reverse leakage current (10 µA @ 1600 V), and operating temperature range (-50°C ~ 150°C). The substitute must also maintain identical mounting type (Through Hole) and package configuration (5-SIP, DBI-B).

Q: Are there packaging differences between the main part and substitute?

A: The main part is listed with unspecified packaging, while the substitute is supplied in Tube packaging. Both components use the same 5-SIP package case and DBI-B supplier device package, ensuring mechanical compatibility in circuit board applications.

Q: What is the inventory status for each part?

A: The main part DBI20-16B has 849 units in stock, while the substitute DBI20-16B has 1235 units available. Both are new original components.

Q: Does the substitute part have different compliance certifications?

A: The substitute part is ROHS3 compliant with REACH information available upon request. The main part lists RoHS status as not applicable and REACH status as vendor undefined. Applications requiring specific regulatory compliance should reference the substitute part documentation.

Q: Can these parts be used interchangeably in three-phase rectification circuits?

A: Yes. Both parts are three-phase bridge rectifiers with identical electrical specifications, operating temperature ranges, and package configurations. They are functionally interchangeable for applications requiring 1.6 kV peak reverse voltage and 3 A average rectified current.
