Substitute Part Grouping Explanation

Substitution of the MB2505W-BP is determined by the following critical parameters:

  • Diode Type: Single Phase (required match)
  • Voltage - Peak Reverse (Max): 50 V (required match)
  • Current - Average Rectified (Io): 25 A (required match)
  • Mounting Type: Through Hole (required match)
  • Package / Case: 4-Square configuration (required match)
  • Technology: Standard (required match)

The KBPC25005W-G qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Both components share identical voltage and current ratings, single-phase rectification topology, through-hole mounting, and 4-square package configuration. Compliance certifications (ROHS3, MSL 1, REACH Unaffected) are equivalent across both parts.

Engineering Selection Recommendations

The KBPC25005W-G is a qualified substitute for the obsolete MB2505W-BP. Selection is based on the following factors:

Electrical Equivalence: Both components meet identical voltage (50V peak reverse) and current (25A average rectified) specifications. The KBPC25005W-G exhibits a lower forward voltage drop (1.1V vs 1.2V @ 12.5A), which represents improved efficiency characteristics.

Compliance Status: The KBPC25005W-G maintains ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, matching the regulatory profile of the original part.

Product Availability: The KBPC25005W-G is classified as Active, ensuring long-term procurement availability and supply chain continuity compared to the obsolete MB2505W-BP.

Operating Temperature: The KBPC25005W-G supports an extended operating temperature range (-55°C ~ 150°C) relative to the MB2505W-BP (-55°C ~ 125°C), providing additional thermal margin in applications.

Package Compatibility: Both components use 4-square through-hole packages with identical mechanical footprints, enabling direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the KBPC25005W-G directly replace the MB2505W-BP in existing designs?

A: Yes. Both components share identical voltage ratings (50V), current ratings (25A), diode type (single phase), mounting method (through hole), and package configuration (4-square). PCB layouts and mechanical mounting require no modification.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Micro Commercial Co vs Comchip Technology), product status (obsolete vs active), forward voltage drop (1.2V vs 1.1V @ 12.5A), and maximum operating temperature (125°C vs 150°C). The KBPC25005W-G offers improved efficiency and extended thermal operating range.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical compliance certifications: ROHS3 Compliant, MSL 1 (Unlimited), and REACH Unaffected status.

Q: Why is the MB2505W-BP classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Micro Commercial Co. The KBPC25005W-G provides functional and electrical equivalence for applications requiring continued component supply.

Q: Does the lower forward voltage of the KBPC25005W-G affect circuit design?

A: The 0.1V difference in forward voltage drop (1.1V vs 1.2V @ 12.5A) represents improved efficiency but does not require circuit redesign. This characteristic is beneficial for power dissipation and thermal management in rectification applications.

Q: Are the package dimensions identical between MB-35W and KBPC-W?

A: Both packages are classified as 4-square through-hole configurations with identical mechanical footprints, enabling direct PCB compatibility without layout modification.
