Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB252 is determined by electrical and mechanical parameter equivalence across the following criteria:

Voltage rating equivalence: Peak reverse voltage of 200V maximum Current rating equivalence: Average rectified current of 25A Forward voltage characteristics: Maximum forward voltage of 1.1V at 12.5A Reverse leakage current: Maximum 10µA at 200V Temperature operating range: -55°C to 150°C junction temperature Diode configuration: Single-phase bridge rectifier with standard technology Mounting and packaging: QC terminal with 4-Square package footprint Regulatory compliance: ROHS3 compliance requirement

The KBPC2502-G from Comchip Technology meets all specified electrical parameters and maintains compatibility with the original MB252 design requirements.

Parameter Comparison

Engineering Selection Recommendations

The KBPC2502-G maintains active product status with Comchip Technology, ensuring ongoing availability and supply chain continuity. Both parts carry ROHS3 compliance certification and identical moisture sensitivity ratings, supporting regulatory and environmental requirements. The QC terminal mounting and 4-Square package configuration remain consistent between the two devices, allowing direct substitution in existing PCB layouts without modification.

Frequently Asked Questions (FAQ)

Q: Can the KBPC2502-G replace the MB252 in existing designs? A: Yes. The KBPC2502-G meets all electrical and mechanical specifications of the MB252, including voltage rating, current capacity, forward voltage characteristics, reverse leakage current, operating temperature range, and package configuration. Direct substitution is supported without circuit redesign.

Q: What is the primary reason for substitution? A: The MB252 is classified as obsolete. The KBPC2502-G is an active product with equivalent specifications, providing procurement continuity and long-term supply availability.

Q: Are there any compliance differences between the two parts? A: Both the MB252 and KBPC2502-G are ROHS3 compliant with identical moisture sensitivity levels. The KBPC2502-G is REACH unaffected, while the MB252 is REACH affected. Both carry the same ECCN and HTSUS classifications.

Q: Does the package footprint differ between these parts? A: No. Both components use QC terminal mounting with 4-Square package configuration. PCB layout modifications are not required for substitution.

Q: What are the key electrical parameters that define substitution eligibility? A: Peak reverse voltage (200V), average rectified current (25A), forward voltage (1.1V @ 12.5A), reverse leakage current (10µA @ 200V), and operating temperature range (-55°C to 150°C) must remain identical for direct substitution.
