Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete P650-U180-WH is determined by the following critical parameters that must remain consistent:

• Series Compatibility: Both parts belong to Bourns Inc.'s TBU® series, ensuring design-level compatibility
• Technology: Internal switch technology maintained across substitutes
• Number of Circuits: 2-circuit configuration preserved
• Application Domain: Ethernet circuit protection maintained
• Mounting Type: Surface mount technology consistent
• Voltage Ratings: Working voltage (300V) and impulse clamping voltage (650V) maintained
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status preserved
• Trade Classification: HTSUS code 8536.30.8000 consistent

The substitute part TBU-DT065-200-WH meets these core substitution criteria while offering active product status and improved moisture sensitivity characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TBU-DT065-200-WH is the qualified substitute for the obsolete P650-U180-WH based on the following engineering criteria:

Product Status: The substitute part maintains active product status with Bourns Inc., ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements for component selection.

Functional Equivalence: The substitute preserves all critical electrical parameters including 300V working voltage, 650V impulse clamping voltage, 2-circuit configuration, and internal switch technology required for Ethernet circuit protection applications.

Moisture Sensitivity: The substitute offers improved moisture sensitivity characteristics (MSL 1 versus MSL 3), providing enhanced reliability during storage and handling phases.

Package Considerations: The substitute utilizes a 4-DFN (5x5) package compared to the 6-DFN (6.25x7.75) package of the main part. PCB layout modifications are required to accommodate the different package footprint and pin configuration.

Frequently Asked Questions (FAQ)

Q: Can TBU-DT065-200-WH be used as a direct replacement for P650-U180-WH without PCB modifications?

A: No. While both parts are functionally equivalent for circuit protection, the package footprints differ. The main part uses a 6-DFN (6.25x7.75) package, while the substitute uses a 4-DFN (5x5) package. PCB layout redesign is required to accommodate the different footprint and pin arrangement.

Q: Are the electrical specifications identical between these two parts?

A: The critical electrical specifications are equivalent. Both parts operate at 300V working voltage with 650V impulse clamping voltage, feature 2-circuit internal switch technology, and are designed for Ethernet circuit protection applications. Current ratings differ (180MA versus 200MA), but both maintain the same voltage protection characteristics.

Q: What is the significance of the MSL rating difference?

A: The substitute part has MSL 1 (unlimited moisture exposure) compared to MSL 3 (168 hours) for the main part. This indicates the substitute has superior moisture resistance and requires less stringent handling and storage conditions, reducing risk during manufacturing and inventory management.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the P650-U180-WH and TBU-DT065-200-WH maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component selection.

Q: What is the base product number relationship?

A: The main part P650-U180-WH has base product number P650-U, while the substitute TBU-DT065-200-WH has base product number TBU-DT065. Both are part of Bourns Inc.'s TBU® series but represent different product lines within the series.
