BR84 Bridge Rectifier Single Phase 400V 8A Equivalent & Substitute Parts

Part Overview

The BR84 is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 400V peak reverse voltage and 8A average rectified current. This component is designed for through-hole mounting applications requiring AC-to-DC conversion in industrial and power supply circuits. The BR84 maintains active product status with 936 units in current inventory stock.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter ranges for this diode category, maintaining functional compatibility while potentially offering alternative sourcing, packaging, or inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BR84 is determined by the following critical parameters:

Voltage Rating: Peak reverse voltage must equal or exceed 400V. The substitute part MP1004G-G meets this requirement at 400V maximum.

Current Rating: Average rectified current must support the 8A specification. The MP1004G-G is rated for 10A, which exceeds the BR84 requirement and is acceptable for substitution.

Forward Voltage Characteristics: Forward voltage drop must not exceed 1.1V at the specified test current. The MP1004G-G specifies 1.1V @ 5A, which is compatible with the BR84 specification.

Reverse Leakage: Reverse leakage current must not exceed 10µA @ 400V. The MP1004G-G meets this specification exactly.

Mounting Configuration: Both parts utilize through-hole mounting with 4-square package geometry, ensuring mechanical compatibility in circuit board layouts.

Diode Type and Technology: Both parts are single-phase standard technology bridge rectifiers, confirming functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (BR84): Recommended for applications where GeneSiC Semiconductor sourcing is established or preferred. Active product status and RoHS compliance confirm ongoing manufacturing support. Current inventory of 936 units supports immediate availability.

Substitute Part (MP1004G-G): The MP1004G-G from Comchip Technology qualifies as a direct substitute based on electrical parameter equivalence. The higher current rating (10A vs. 8A) provides design margin without compromising performance. ROHS3 compliance and wider operating temperature range (-55°C to 150°C) offer additional environmental flexibility. Higher inventory availability (3295 units) supports supply chain continuity. Both parts carry EAR99 ECCN classification and identical HTSUS codes, confirming regulatory equivalence.

Selection between BR84 and MP1004G-G should be based on supplier availability, lead time requirements, and established procurement relationships rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can MP1004G-G replace BR84 in existing circuit designs?

A: Yes. Both parts meet identical voltage and current specifications for single-phase bridge rectification at 400V and 8A operation. Through-hole mounting and 4-square package geometry ensure mechanical compatibility in standard PCB layouts.

Q: What is the significance of the higher 10A current rating on MP1004G-G?

A: The MP1004G-G 10A rating exceeds the BR84 8A requirement, providing operational margin. This does not create incompatibility; the substitute part simply has higher current capacity than required by the application.

Q: Are there differences in forward voltage drop between these parts?

A: Both parts specify maximum forward voltage of 1.1V. The MP1004G-G measurement is taken at 5A versus 1A for the BR84, but the maximum specification remains equivalent at 1.1V.

Q: Does the wider operating temperature range of MP1004G-G affect compatibility?

A: No. The MP1004G-G range of -55°C to 150°C encompasses the BR84 range of -65°C to 125°C. The substitute part operates across a broader temperature window, which does not create incompatibility with designs specified for the narrower BR84 range.

Q: Are packaging differences between BR-8 and MP-8 a concern?

A: Both use 4-square through-hole package geometry. The different designations (BR-8 vs. MP-8) reflect manufacturer nomenclature but represent mechanically compatible packages suitable for identical PCB footprints.

Q: What compliance certifications apply to both parts?

A: Both BR84 and MP1004G-G are RoHS compliant (BR84: RoHS Compliant; MP1004G-G: ROHS3 Compliant), carry MSL Level 1 (Unlimited) moisture sensitivity rating, and share identical EAR99 ECCN and 8541.10.0080 HTSUS classifications.

Q: Which part should be selected for new designs?

A: Selection should be based on supplier availability, procurement lead times, and inventory status rather than electrical performance. Both parts are functionally equivalent for 400V 8A single-phase bridge rectification applications.
