KBJ2504G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBJ2504G is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 400 V peak reverse voltage and 25 A average rectified current. This component is designed for through-hole mounting in the standard KBJ package configuration and operates across the temperature range of -55°C to 125°C. The part maintains Active product status and is RoHS Compliant with unlimited moisture sensitivity level classification.

Substitute parts become necessary when the primary component experiences supply constraints, inventory limitations, or when design requirements permit operation at lower current ratings while maintaining the same voltage class and package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBJ2504G is constrained by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - Peak Reverse (Max): 400 V
• Mounting Type: Through Hole
• Package / Case: 4-SIP, KBJ
• Diode Type: Single Phase
• Technology: Standard

Flexible Parameters (Lower Ratings Acceptable):

• Current - Average Rectified (Io): Substitute parts may operate at lower current ratings provided the application does not exceed the substitute's rated current capacity
• Operating Temperature Range: Substitute parts with extended or equivalent temperature ranges are acceptable
• Voltage - Forward (Vf): Minor variations within the 400 V class are acceptable
• Current - Reverse Leakage: Lower leakage values are acceptable

The KBJ2504G can be substituted with lower-current-rated bridge rectifiers in the same voltage class and package when circuit design permits reduced current capacity. The substitute parts KBJ404G and KBJ604G maintain the 400 V rating and KBJ package configuration but operate at 4 A and 6 A respectively, making them suitable for applications with lower current demands.

Parameter Comparison

Engineering Selection Recommendations

KBJ2504G (Primary Component): The KBJ2504G is the specified component for applications requiring 25 A average rectified current at 400 V. This part maintains Active product status, RoHS Compliance, and is available in bulk packaging with 859 pieces in stock.

KBJ404G (Substitute for Lower Current Applications): The KBJ404G is suitable for applications where the circuit design permits operation at 4 A average rectified current. This part is manufactured by Diodes Incorporated, maintains ROHS3 Compliance, and features an extended operating temperature range of -65°C to 150°C. The KBJ404G is available in tube packaging with 928 pieces in stock.

KBJ604G (Substitute for Moderate Current Applications): The KBJ604G is suitable for applications where the circuit design permits operation at 6 A average rectified current. This part is manufactured by Diodes Incorporated, maintains ROHS3 Compliance, and features an extended operating temperature range of -65°C to 150°C. The KBJ604G is available in tube packaging with 2294 pieces in stock.

Both substitute parts maintain the 400 V voltage rating, single-phase diode type, standard technology classification, and KBJ package configuration. Selection between KBJ404G and KBJ604G depends on the specific current requirements of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the KBJ404G or KBJ604G be used in place of the KBJ2504G?

A: The KBJ404G and KBJ604G can be used as substitutes only if the application circuit operates at or below their respective current ratings (4 A and 6 A). The KBJ2504G is rated for 25 A; substitution with lower-rated parts is only valid when the actual circuit current demand does not exceed the substitute's rating.

Q: What are the key compatibility requirements for substitution?

A: Substitute parts must maintain the following parameters: 400 V peak reverse voltage rating, single-phase diode type, standard technology, through-hole mounting, and 4-SIP KBJ package configuration. All listed substitutes meet these requirements.

Q: Are there differences in compliance certifications between the main part and substitutes?

A: The KBJ2504G is RoHS Compliant. The KBJ404G and KBJ604G are ROHS3 Compliant, which represents a more recent compliance standard. Both compliance levels are acceptable for equivalent substitution purposes.

Q: How do the operating temperature ranges compare?

A: The KBJ2504G operates from -55°C to 125°C. The KBJ404G and KBJ604G operate from -65°C to 150°C, providing an extended temperature range. Applications operating within the KBJ2504G temperature range will function within the substitute parts' ranges.

Q: What is the difference between bulk and tube packaging?

A: The KBJ2504G is supplied in bulk packaging (859 pieces in stock). The KBJ404G and KBJ604G are supplied in tube packaging (928 and 2294 pieces respectively). Packaging format does not affect electrical or mechanical compatibility; selection depends on procurement and assembly requirements.

Q: Can the KBJ404G and KBJ604G be used interchangeably with each other?

A: The KBJ404G and KBJ604G are not interchangeable with each other due to different current ratings (4 A versus 6 A). Selection between these two parts depends on the specific current requirements of the application circuit.
