Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0805J2002P00BUT is determined by the following critical parameters:

• Capacitance Value: Must be 2 pF
• Tolerance: Must be ±0.1pF
• Temperature Coefficient: Must be C0G/NP0
• Package / Case: Must be 0805 (2012 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 2.00mm L x 1.25mm W x 1.30mm Max Thickness
• Operating Temperature Range: Must be -55°C to 125°C

The substitute part 0805J2502P00BUT meets all these criteria. The only parameter that differs is the voltage rating, which is increased from 200V to 250V. A higher voltage rating does not compromise circuit functionality when the original design voltage requirement is 200V or lower, as the component will operate within its specified electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the 0805J2002P00BUT and 0805J2502P00BUT are active production parts with full ROHS3 compliance and REACH unaffected status. The substitute part 0805J2502P00BUT offers the advantage of a higher voltage rating (250V versus 200V) while maintaining identical electrical performance in capacitance, tolerance, and temperature stability. Both parts carry MSL Level 1 rating, indicating unlimited shelf life without moisture sensitivity constraints.

Selection between these parts should be based on circuit voltage requirements. If the design operates at or below 200V, either part is suitable. If design margins or future voltage headroom is required, the 0805J2502P00BUT provides additional voltage safety margin without any compromise to physical form factor or electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can 0805J2502P00BUT be used as a direct replacement for 0805J2002P00BUT?

A: Yes, when circuit voltage requirements are 200V or lower. The substitute part has identical capacitance (2 pF), tolerance (±0.1pF), temperature coefficient (C0G/NP0), package (0805), and physical dimensions. The higher voltage rating (250V) does not affect compatibility.

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

A: The voltage rating indicates the maximum voltage the capacitor can safely withstand. A 250V-rated capacitor can be used in applications rated for 200V or lower without performance degradation. The higher rating provides additional design margin.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 0805 (2012 Metric) package with dimensions of 2.00mm L x 1.25mm W and maximum thickness of 1.30mm. They are mechanically interchangeable on PCBs designed for 0805 components.

Q: Do both parts have the same temperature stability?

A: Yes. Both parts feature C0G/NP0 temperature coefficient and operate across the identical temperature range of -55°C to 125°C, ensuring stable capacitance performance in thermal cycling applications.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 rating. They meet identical regulatory and environmental standards.

Q: Which part should be selected for new designs?

A: Selection depends on circuit voltage requirements. For applications operating at 200V, either part is acceptable. For designs requiring voltage margin or future flexibility, 0805J2502P00BUT is the preferred choice due to its higher voltage rating.
