Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0805J2002P00DUT is determined by the following critical parameters:

• Capacitance Value: Must be 2 pF to maintain circuit function
• Temperature Coefficient: Must be C0G/NP0 for frequency stability
• Package / Case: Must be 0805 (2012 Metric) for mechanical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C
• Physical Dimensions: Must match 0.079" L x 0.049" W (2.00mm x 1.25mm) and 0.051" (1.30mm) maximum thickness

The substitute part 0805J2502P00BUT meets all mechanical and electrical compatibility criteria. While the rated voltage is increased to 250V and tolerance is tightened to ±0.1pF, these represent improvements that do not compromise circuit performance in applications rated for 200V operation.

Parameter Comparison

Engineering Selection Recommendations

Both the 0805J2002P00DUT and 0805J2502P00BUT are active production parts from Knowles Syfer with full ROHS3 compliance and REACH unaffected status. The substitute part 0805J2502P00BUT provides identical capacitance and temperature coefficient performance with improved voltage rating (250V versus 200V) and tighter tolerance (±0.1pF versus ±0.5pF). Selection between these parts depends on application voltage requirements and tolerance specifications. For circuits operating at or below 200V with tolerance requirements of ±0.5pF or greater, either part is suitable. For applications requiring higher voltage margin or tighter tolerance control, the 0805J2502P00BUT is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 0805J2502P00BUT be used as a direct replacement for the 0805J2002P00DUT?

A: Yes. Both parts share identical capacitance (2 pF), temperature coefficient (C0G/NP0), package (0805), and physical dimensions. The substitute part has a higher voltage rating (250V) and tighter tolerance (±0.1pF), which are compatible with applications designed for the original part.

Q: What is the difference in tolerance between these parts?

A: The main part has ±0.5pF tolerance, while the substitute has ±0.1pF tolerance. The tighter tolerance of the substitute part does not affect compatibility; it represents improved performance.

Q: Are both parts suitable for RF and microwave applications?

A: Yes. Both parts are specified for RF and microwave applications with identical feature sets: High Q, Low Loss, and Ultra Low ESR.

Q: Do these parts have the same moisture sensitivity level?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can I use the 0805J2502P00BUT in a circuit designed for 200V operation?

A: Yes. The substitute part is rated for 250V, which exceeds the 200V requirement. Higher voltage rating does not compromise performance in lower-voltage applications.

Q: Are there any packaging differences between these parts?

A: The main part packaging is not specified in the provided data. The substitute part is supplied in Tape & Reel (TR) format. Verify packaging compatibility with your assembly process requirements.
