KBP204 Bridge Rectifier Single Phase 400V 2A Equivalent & Substitute Parts

Part Overview

The KBP204 is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 400V peak reverse voltage and 2A average rectified current. This component is designed for through-hole mounting applications requiring standard bridge rectification in AC-to-DC conversion circuits. The part maintains Active product status with 865 units in current inventory stock.

Substitute parts are identified when electrical specifications and mechanical compatibility align within the defined tolerance parameters for this diode category. Substitution becomes necessary due to supply chain availability, inventory levels, or specific packaging requirements while maintaining functional equivalence in the target application.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KBP204 are qualified based on strict electrical and mechanical parameter alignment. The substitution logic requires equivalence in the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Peak Reverse (Max): 400 V (exact match required)
• Current - Average Rectified (Io): 2 A (exact match required)
• Diode Type: Single Phase (exact match required)
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A (exact match required)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (exact match required)
• Package / Case: KBP form factor (exact match required)

Compliance Criteria:

• RoHS Status: Compliant or equivalent certification
• ECCN Classification: EAR99 (matching export control classification)

The KBP204G from SMC Diode Solutions satisfies all substitution criteria and qualifies as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

KBP204 (GeneSiC Semiconductor) is the primary specification part with Active product status and confirmed inventory availability. This part is suitable for direct procurement when GeneSiC supply chain access is established and bulk packaging meets assembly requirements.

KBP204G (SMC Diode Solutions) qualifies as a direct electrical and mechanical substitute. This part maintains Active product status with higher inventory levels (1230 units versus 865 units). The KBP204G demonstrates equivalent RoHS compliance (ROHS3 Compliant) and matching ECCN classification (EAR99). The extended operating temperature range (-55°C to 150°C versus -50°C to 150°C) provides additional thermal margin for applications requiring lower temperature operation. The lower reverse leakage current (5 µA @ 400 V versus 10 µA @ 50 V) indicates improved leakage characteristics.

Both parts are suitable for selection based on availability, supply chain preference, and packaging format requirements. The choice between KBP204 and KBP204G depends on procurement lead time, inventory allocation, and whether bulk or tube packaging aligns with assembly operations.

Frequently Asked Questions (FAQ)

Q: Can KBP204G replace KBP204 in existing circuit designs?

A: Yes. The KBP204G meets all critical electrical specifications: 400V peak reverse voltage, 2A average rectified current, 1.1V forward voltage drop at 2A, and single-phase bridge rectification topology. Both parts use through-hole mounting with KBP package compatibility. No circuit redesign is required.

Q: What is the difference between 4-SIP and 4-ESIP packaging?

A: Both designations refer to 4-pin Single In-line Package variants within the KBP form factor. The physical footprint and pin spacing remain compatible for through-hole PCB mounting. The "E" designation in 4-ESIP indicates an enhanced or variant specification within the same mechanical envelope. Both packages are mechanically interchangeable on standard KBP footprints.

Q: Does the lower reverse leakage current in KBP204G affect circuit performance?

A: The KBP204G exhibits lower reverse leakage (5 µA @ 400 V) compared to KBP204 (10 µA @ 50 V). Lower leakage current reduces standby power dissipation and improves circuit efficiency. This characteristic is beneficial in all applications and does not introduce compatibility issues.

Q: Are there temperature range differences between these parts?

A: The KBP204G operating range extends to -55°C (versus -50°C for KBP204) at the lower limit, while both maintain 150°C upper limit. The KBP204G provides additional thermal margin for applications requiring operation below -50°C. For standard industrial temperature ranges (-40°C to 85°C or -50°C to 125°C), both parts are functionally equivalent.

Q: What packaging format should be selected for high-volume assembly?

A: KBP204 is supplied in Bulk packaging, while KBP204G is supplied in Tube packaging. Tube packaging is standard for automated pick-and-place assembly operations. Bulk packaging is suitable for manual assembly or when component trays are used. Selection depends on assembly process requirements and handling procedures.

Q: Are both parts RoHS compliant?

A: Yes. KBP204 is RoHS Compliant, and KBP204G is ROHS3 Compliant. Both meet RoHS directive requirements for hazardous substance restrictions. ROHS3 represents the current RoHS 2.0/3.0 standard. Both parts are suitable for applications requiring RoHS compliance.

Q: What is the REACH status of these parts?

A: KBP204G is marked as REACH Affected, indicating it falls under REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory scope. KBP204 REACH status is not specified in available documentation. For applications requiring REACH compliance verification, KBP204G provides explicit compliance documentation.
