Key Parameters

Substitute Part Grouping Explanation

Substitution of the PB88-BP is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Package / Case: 4-Square, PB-10
• Operating Temperature Range: -55°C to 125°C (minimum)

Electrical Performance Criteria:

• Current - Average Rectified (Io): 8 A (minimum required)
• Voltage - Peak Reverse (Max): Must equal or exceed 800 V
• Voltage - Forward (Vf) (Max) @ If: Must not exceed 1.1 V @ 4 A
• Current - Reverse Leakage @ Vr: Must not exceed 10 µA at rated voltage

The PB810-BP qualifies as a manufacturer-recommended substitute because it maintains identical mechanical compatibility, mounting configuration, and thermal operating range while providing equal or superior electrical performance across all specified parameters.

Engineering Selection Recommendations

The PB810-BP is the manufacturer-recommended substitute for the obsolete PB88-BP. Selection of the PB810-BP is supported by the following factors:

Product Status: The PB810-BP maintains active product status with Micro Commercial Co, ensuring continued availability and supply chain reliability compared to the obsolete PB88-BP.

Electrical Compatibility: The PB810-BP provides a peak reverse voltage rating of 1 kV, which exceeds the 800 V requirement of the original PB88-BP. This higher voltage rating ensures the substitute operates within safe margins in applications designed for the original component.

Mechanical and Thermal Compatibility: Both components share identical mounting type (through hole), package configuration (4-Square, PB-10), and operating temperature range (-55°C to 125°C), ensuring direct physical and thermal compatibility in existing circuit designs.

Electrical Performance: Forward voltage drop, average rectified current, and reverse leakage characteristics are identical between the two components, confirming functional equivalence in rectification performance.

Compliance: Both components maintain identical REACH status (REACH Unaffected) and ECCN classification (EAR99), ensuring regulatory compliance is maintained during substitution.

Frequently Asked Questions (FAQ)

Q: Can the PB810-BP be used as a direct replacement for the PB88-BP in existing designs?

A: Yes. The PB810-BP is mechanically and electrically compatible with the PB88-BP. Both components use identical through-hole mounting in the 4-Square PB-10 package, operate across the same temperature range, and deliver identical rectification performance. The higher voltage rating of the PB810-BP (1 kV versus 800 V) provides additional safety margin without affecting circuit operation.

Q: What is the primary difference between the PB88-BP and PB810-BP?

A: The primary difference is the peak reverse voltage rating. The PB88-BP is rated for 800 V, while the PB810-BP is rated for 1 kV. All other electrical parameters, including forward voltage, current capacity, and reverse leakage, are identical. The PB810-BP also maintains active product status, whereas the PB88-BP is obsolete.

Q: Are there any circuit design considerations when substituting the PB810-BP for the PB88-BP?

A: No design modifications are required. The identical forward voltage drop (1.1 V @ 4 A), average rectified current (8 A), and operating temperature range ensure the PB810-BP functions identically to the PB88-BP in the original circuit. The higher voltage rating of the PB810-BP does not affect circuit performance.

Q: Is the PB810-BP available in the same packaging as the PB88-BP?

A: Yes. Both components use the 4-Square, PB-10 through-hole package. Physical dimensions and pin configuration are identical, enabling direct board-level substitution without layout modifications.

Q: What is the inventory status of the PB810-BP?

A: The PB810-BP is available with 761 pieces in new original stock. As an active product from Micro Commercial Co, ongoing supply is supported compared to the obsolete PB88-BP.

Q: Do regulatory certifications change when substituting the PB810-BP for the PB88-BP?

A: No. Both components maintain identical REACH status (REACH Unaffected) and ECCN classification (EAR99). Regulatory compliance is maintained during substitution.
