Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KBJ402G is determined by strict equivalence across critical electrical and mechanical parameters. The following parameters must match or exceed the main part specifications:

Critical Parameters (Must Match Exactly):

• Voltage - Peak Reverse (Max): 200V
• Current - Average Rectified (Io): 4A
• Diode Type: Single Phase
• Mounting Type: Through Hole
• Package / Case: 4-SIP, KBJ

Important Parameters (Must Meet or Exceed):

• Operating Temperature Range: minimum -55°C, maximum 150°C
• Voltage - Forward (Vf): must not exceed specified limits at rated current
• Current - Reverse Leakage: must not exceed specified limits at rated voltage
• RoHS Compliance: must maintain regulatory status

The KBJ402G manufactured by Diodes Incorporated qualifies as a direct substitute based on identical electrical ratings, matching package configuration, and compatible thermal and compliance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the GeneSiC Semiconductor KBJ402G and Diodes Incorporated KBJ402G are active products suitable for direct substitution in applications requiring single-phase bridge rectification at 200V, 4A specifications.

GeneSiC Semiconductor KBJ402G is the primary specified component with RoHS compliance and an operating temperature range of -55°C to 150°C. This part is currently in active production status with 907 units available in stock.

Diodes Incorporated KBJ402G qualifies as a direct substitute with identical electrical ratings and package configuration. This variant offers an extended lower operating temperature limit of -65°C, providing enhanced performance in cold-temperature environments. The forward voltage specification of 1V @ 2A indicates superior efficiency characteristics compared to the main part. ROHS3 compliance status meets current regulatory requirements. Current inventory shows 669 units available in tube packaging.

Selection between these two sources should be based on:

• Supply chain availability and lead time requirements
• Packaging preference (bulk versus tube)
• Thermal environment of the application
• Regulatory compliance documentation requirements

Both parts maintain identical critical electrical parameters and mechanical compatibility, ensuring direct PCB-level interchangeability without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the Diodes Incorporated KBJ402G be used as a direct replacement for the GeneSiC Semiconductor KBJ402G?

A: Yes. Both parts share identical part numbers, electrical ratings (200V peak reverse voltage, 4A average rectified current), and 4-SIP KBJ package configuration. The Diodes Incorporated variant offers extended low-temperature operation (-65°C minimum versus -55°C) and superior forward voltage characteristics, making it electrically and mechanically compatible for direct substitution.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by five critical parameters: Voltage - Peak Reverse (Max) of 200V, Current - Average Rectified (Io) of 4A, Single Phase diode type, Through Hole mounting type, and 4-SIP KBJ package configuration. Any deviation in these parameters disqualifies a part from direct substitution.

Q: Does packaging format affect substitution compatibility?

A: Packaging format (bulk versus tube) does not affect electrical or mechanical compatibility. Both formats contain identical components with the same electrical specifications and physical dimensions. Packaging selection is based on procurement, storage, and assembly process requirements rather than functional compatibility.

Q: Are there temperature-related considerations when substituting between these parts?

A: The Diodes Incorporated variant operates from -65°C to 150°C, while the GeneSiC part operates from -55°C to 150°C. For applications operating below -55°C, the Diodes Incorporated part provides extended capability. For standard temperature-range applications (-55°C to 150°C), both parts are functionally equivalent.

Q: What compliance certifications apply to these parts?

A: The GeneSiC Semiconductor KBJ402G carries RoHS compliance certification. The Diodes Incorporated KBJ402G carries ROHS3 compliance certification and is REACH Unaffected. Both parts meet current regulatory requirements for electronic component manufacturing and use.

Q: Can these parts be mixed in the same production batch or assembly?

A: Yes. Both parts are electrically and mechanically identical at the component level. Mixed sourcing from GeneSiC Semiconductor and Diodes Incorporated does not create compatibility issues, though standard quality assurance practices should verify component traceability and documentation for each source.
