KBU1002 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBU1002 is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 200 V peak reverse voltage and 10 A average rectified current. This component is designed for through-hole mounting applications requiring AC-to-DC conversion in industrial and power supply circuits. The part maintains Active product status with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified based on matching voltage ratings, mounting type, and package compatibility while accounting for current rating variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KBU1002 is determined by the following criteria:

Primary Matching Parameters:

• Voltage - Peak Reverse (Max): 200 V
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Secondary Consideration Parameters:

• Current - Average Rectified (Io): Equal or greater rating
• Package / Case: Compatible 4-SIP form factor
• RoHS Compliance: Active compliance status

The GBU602-G from Comchip Technology qualifies as a substitute based on matching voltage rating (200 V), single-phase configuration, standard technology, through-hole mounting, and identical operating temperature range. The current rating of 6 A is lower than the KBU1002's 10 A specification; therefore, the GBU602-G is suitable only for applications requiring 6 A or less average rectified current.

Engineering Selection Recommendations

KBU1002 Selection Criteria:

• Applications requiring 10 A average rectified current at 200 V peak reverse voltage
• Circuits where forward voltage drop of 1.05 V @ 10 A is acceptable
• Systems operating within -55°C to 150°C junction temperature range
• RoHS-compliant designs requiring GeneSiC Semiconductor sourcing

GBU602-G Selection Criteria:

• Applications requiring 6 A or less average rectified current at 200 V peak reverse voltage
• Circuits where lower reverse leakage current (5 µA @ 200 V) is beneficial
• Systems requiring Comchip Technology component sourcing
• ROHS3 compliance requirements
• Through-hole PCB assembly with 4-SIP package compatibility

Both parts maintain Active product status and meet environmental compliance standards. Selection between KBU1002 and GBU602-G depends on circuit current requirements and manufacturer sourcing constraints.

Frequently Asked Questions (FAQ)

Q: Can GBU602-G directly replace KBU1002 in all applications?

A: No. The GBU602-G has a maximum average rectified current rating of 6 A compared to the KBU1002's 10 A rating. Direct replacement is only suitable for applications requiring 6 A or less. Exceeding this current rating will cause component failure.

Q: Are the package dimensions identical between KBU1002 and GBU602-G?

A: Both parts use 4-SIP through-hole package form factors. While the physical footprint is compatible for PCB mounting, the KBU package and GBU package designations indicate manufacturer-specific package specifications. Verify mechanical dimensions with respective datasheets before final assembly.

Q: What is the significance of the different forward voltage test conditions?

A: The KBU1002 specifies Vf at 10 A, while GBU602-G specifies Vf at 3 A. These different test conditions reflect the parts' rated current capabilities. Direct voltage comparison is not valid due to different test currents. Consult full datasheets for forward voltage characteristics across the operating current range.

Q: Are both parts RoHS compliant?

A: Yes. The KBU1002 is RoHS Compliant, and the GBU602-G is ROHS3 Compliant. Both meet environmental compliance requirements for restricted substance use.

Q: What is the moisture sensitivity level for both parts?

A: Both the KBU1002 and GBU602-G have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Can I use KBU1002 in place of GBU602-G?

A: Yes, the KBU1002 can substitute for GBU602-G in applications requiring up to 10 A average rectified current. The KBU1002 provides higher current capacity and is backward compatible with GBU602-G applications. Verify that circuit design accommodates the higher forward voltage drop characteristics.
