PBPC1004 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The PBPC1004 is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for 400 V peak reverse voltage and 8 A average rectified current. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Bridge rectifiers in this voltage and current class are used in power supply circuits, battery charging systems, and AC-to-DC conversion applications where single-phase rectification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PBPC1004 is determined by the following critical parameters:

• Voltage Rating: Peak reverse voltage must be 400 V or higher
• Current Rating: Average rectified current must be 8 A or higher
• Forward Voltage: Maximum forward voltage drop at rated current must not exceed 1.1 V @ 5 A
• Reverse Leakage: Maximum reverse leakage current must not exceed 10 µA @ 400 V
• Mounting Type: Through-hole mounting required for PCB compatibility
• Package Type: 4-Square package configuration (PBPC-8 or equivalent MP-8)
• Diode Type: Single-phase bridge rectifier topology
• Technology: Standard rectifier technology

The MP1004G-G from Comchip Technology meets all substitution criteria with equivalent or superior electrical characteristics and maintains the same through-hole mounting and package footprint.

Parameter Comparison

Engineering Selection Recommendations

The MP1004G-G is a direct substitute for the PBPC1004 based on the following factors:

• Both components are ROHS3 compliant, meeting environmental and regulatory requirements
• The MP1004G-G maintains identical electrical performance at the critical operating points (voltage rating, forward voltage, reverse leakage)
• The substitute component has a higher current rating (10 A vs. 8 A), providing design margin without compromising performance
• The MP1004G-G has an extended operating temperature range (-55°C ~ 150°C vs. -65°C ~ 125°C), suitable for a broader range of applications
• Both components use identical through-hole mounting and 4-square package configuration, ensuring PCB compatibility without layout modifications
• The MP1004G-G is actively manufactured and in stock, eliminating supply chain risk associated with the obsolete PBPC1004

Frequently Asked Questions (FAQ)

Q: Can the MP1004G-G be used as a direct replacement for the PBPC1004 without PCB modifications?

A: Yes. Both components use through-hole mounting with identical 4-square package footprints (PBPC-8 and MP-8 respectively). No PCB layout changes are required.

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

A: The MP1004G-G is rated for 10 A average rectified current compared to the PBPC1004's 8 A rating. This provides additional design margin and allows the substitute to handle higher load currents without thermal stress, while maintaining identical forward voltage characteristics.

Q: Are there compliance differences between the two parts?

A: Both components are ROHS3 compliant. The PBPC1004 is REACH Affected, while the MP1004G-G is REACH Unaffected. Both carry the same ECCN (EAR99) and HTSUS classifications.

Q: Why is the operating temperature range different?

A: The MP1004G-G has a wider operating temperature range (-55°C ~ 150°C) compared to the PBPC1004 (-65°C ~ 125°C). This extended range does not affect substitution compatibility and may provide benefits in temperature-extreme applications.

Q: What parameters must remain constant for substitution to be valid?

A: Peak reverse voltage (400 V), forward voltage drop (1.1 V @ 5 A), reverse leakage current (10 µA @ 400 V), mounting type (through-hole), and package configuration (4-square) must all be maintained or exceeded for electrical and mechanical compatibility.
