Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0805J2002P70CUT is determined by the following critical parameters:

• Capacitance value must remain 2.7 pF
• Package and case designation must be 0805 (2012 Metric)
• Temperature coefficient must be C0G/NP0
• Operating temperature range must be -55°C to 125°C
• Mounting type must be Surface Mount, MLCC
• Physical dimensions must be identical

The substitute part 0805J2502P70BUT meets all these criteria. The primary difference is an upgrade in voltage rating from 200V to 250V and an improvement in tolerance from ±0.25pF to ±0.1pF. These changes represent enhancements that do not compromise compatibility in applications designed for the original 200V specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 0805J2002P70CUT and 0805J2502P70BUT are active production parts with full regulatory compliance. The 0805J2502P70BUT offers a higher voltage rating (250V versus 200V) and tighter tolerance (±0.1pF versus ±0.25pF) while maintaining identical physical form factor and electrical characteristics for RF and microwave applications. Selection between these parts depends on circuit voltage requirements and tolerance specifications. The substitute part is suitable for applications where the original 200V specification is not a limiting constraint and where improved tolerance performance is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the 0805J2502P70BUT be used as a direct replacement for the 0805J2002P70CUT?

A: Yes, the 0805J2502P70BUT is mechanically and electrically compatible as a substitute. Both parts share identical capacitance values, package dimensions, temperature coefficients, and operating temperature ranges. The substitute features a higher voltage rating and tighter tolerance, which do not create compatibility issues in applications designed for the original part.

Q: What is the primary difference between these two parts?

A: The main differences are voltage rating (250V versus 200V) and tolerance specification (±0.1pF versus ±0.25pF). The substitute part provides enhanced voltage margin and improved capacitance accuracy.

Q: Are both parts available in the same packaging format?

A: The main part is available in standard packaging, while the substitute is supplied in Tape & Reel (TR) format. Both use the identical 0805 (2012 Metric) package case. Packaging format does not affect electrical or mechanical compatibility.

Q: Do these parts meet the same compliance standards?

A: Yes, both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes. Moisture sensitivity level is MSL 1 (Unlimited) for both parts.

Q: Which part should be selected for new designs?

A: Selection is based on circuit voltage requirements. If the application operates at or below 200V, either part is suitable. If higher voltage margin is desired or if tighter tolerance is required, the 0805J2502P70BUT is the appropriate choice.
