Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0805J2002P70BUT is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Capacitance: 2.7 pF
• Tolerance: ±0.1pF
• Temperature Coefficient: C0G, NP0
• Package / Case: 0805 (2012 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C

Allowable Variation Parameters:

• Voltage - Rated: Equal or higher voltage rating
• Manufacturer: Same manufacturer (Knowles Syfer)
• Packaging Format: May differ (Tape & Reel vs. bulk)

The identified substitute part 0805J2502P70BUT maintains all critical electrical and mechanical parameters while providing an upgraded voltage rating of 250V, compared to the original 200V specification. This upgrade is permissible in applications where the higher voltage rating does not create design conflicts.

Parameter Comparison

Engineering Selection Recommendations

Both the 0805J2002P70BUT and 0805J2502P70BUT are active production components manufactured by Knowles Syfer with ROHS3 compliance and REACH unaffected status. The substitute part 0805J2502P70BUT provides identical electrical performance and mechanical compatibility with an elevated voltage rating of 250V. Selection between these components depends on circuit voltage requirements: the original 200V rating is suitable for applications operating at or below 200V, while the 250V substitute accommodates designs requiring higher voltage margins or operating in elevated voltage environments. Both components maintain identical capacitance, tolerance, temperature stability, and physical form factor, ensuring direct PCB-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can 0805J2502P70BUT replace 0805J2002P70BUT in all applications?

A: The 0805J2502P70BUT is electrically and mechanically compatible with 0805J2002P70BUT. The higher voltage rating (250V vs. 200V) does not create incompatibility in circuits designed for 200V operation. Substitution is valid when circuit voltage requirements do not exceed 250V.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components use the 0805 (2012 Metric) package with identical dimensions: 2.00mm length, 1.25mm width, and 1.30mm maximum thickness. PCB footprints and assembly processes remain unchanged.

Q: What is the significance of the C0G/NP0 temperature coefficient?

A: C0G and NP0 designations indicate negligible temperature coefficient characteristics, ensuring capacitance stability across the -55°C to 125°C operating range. Both substitute parts maintain this specification identically.

Q: Does the packaging format difference affect component selection?

A: The main part uses standard packaging while the substitute is available in Tape & Reel (TR) format. This difference affects supply chain logistics and handling but does not impact electrical or mechanical performance. Component selection should consider procurement and assembly requirements.

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

A: Yes. Both the 0805J2002P70BUT and 0805J2502P70BUT are specified for RF and microwave applications with high Q, low loss, and ultra-low ESR characteristics. Electrical performance in these applications remains equivalent.
