MP504W Bridge Rectifier Single Phase 400V 50A Equivalent & Substitute Parts

Part Overview

The MP504W is a single-phase bridge rectifier rated for 400V peak reverse voltage with 50A average rectified current capacity. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and component procurement. The MP504W operates across a wide temperature range of -50°C to 150°C and is housed in a 4-Square MP-50W through-hole package. Due to its obsolete status, equivalent parts with identical electrical and mechanical specifications are required for system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP504W is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part MP504W-BP maintains identical specifications for voltage rating, current capacity, forward voltage characteristics, reverse leakage current, operating temperature range, and physical package configuration. Both parts are manufactured by Micro Commercial Co and utilize standard bridge rectifier technology in the 4-Square MP-50W form factor.

The primary distinction between the main part and substitute is packaging format (tape and reel versus bulk) and product status classification. The MP504W-BP is designated as "Not For New Designs," while the original MP504W is obsolete. Both parts meet the same electrical and thermal requirements for direct substitution in existing applications.

Parameter Comparison

Engineering Selection Recommendations

The MP504W-BP serves as a direct electrical and mechanical equivalent to the MP504W. All critical performance parameters—voltage rating, current capacity, forward voltage drop, reverse leakage, temperature range, and package dimensions—are identical between the two parts.

The MP504W-BP carries ROHS3 compliance status, whereas the original MP504W is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements. The MP504W-BP is classified as "Not For New Designs," indicating limited long-term availability, while the MP504W is obsolete. Both parts are manufactured by Micro Commercial Co and share the same REACH and ECCN classifications.

Selection between these parts should be based on regulatory compliance requirements and procurement availability. The MP504W-BP is suitable for applications requiring RoHS3 compliance. Both parts are electrically and mechanically interchangeable for through-hole PCB assembly applications requiring 400V, 50A single-phase bridge rectification.

Frequently Asked Questions (FAQ)

Q: Can MP504W-BP replace MP504W in existing applications? A: Yes. The MP504W-BP is electrically and mechanically equivalent. All electrical parameters, operating temperature range, and package configuration are identical. Direct substitution is possible for through-hole PCB assembly.

Q: What is the difference between MP504W and MP504W-BP? A: The primary differences are packaging format and product status. MP504W-BP is supplied in bulk packaging, while MP504W uses standard packaging. MP504W-BP is ROHS3 compliant; MP504W is RoHS non-compliant. Both are manufactured by Micro Commercial Co with identical electrical specifications.

Q: Are there any compliance considerations when substituting these parts? A: Yes. If your application requires RoHS3 compliance, MP504W-BP is the appropriate choice. The original MP504W does not meet RoHS requirements. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: Will MP504W-BP fit the same PCB footprint as MP504W? A: Yes. Both parts use the 4-Square MP-50W through-hole package configuration. PCB layout and mounting requirements are identical.

Q: What is the current availability status of these parts? A: MP504W is obsolete. MP504W-BP is classified as "Not For New Designs," indicating limited future availability. Procurement planning should account for these status classifications.
