Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0603J2002P70BCT is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 2.7 pF
• Tolerance: ±0.1pF
• Temperature coefficient: C0G/NP0
• Package code: 0603 (1608 Metric)
• Mounting type: Surface Mount, MLCC

Allowable Variation Parameters:

• Voltage rating: Equal to or greater than 200V
• Physical thickness: Within component height constraints of the application
• Manufacturer: Different manufacturers acceptable if all mandatory parameters match

The substitute part CQ0603BRNPOYBN2R7 from YAGEO meets all mandatory matching criteria and provides an elevated voltage rating of 250V, making it suitable for applications requiring higher voltage margin or operating in more demanding electrical environments.

Parameter Comparison

Engineering Selection Recommendations

Both the 0603J2002P70BCT and CQ0603BRNPOYBN2R7 are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on the following criteria:

Primary Part (0603J2002P70BCT): Use when the design specifies Knowles Syfer as the preferred manufacturer or when the 200V rating is sufficient for the application voltage margin requirements.

Substitute Part (CQ0603BRNPOYBN2R7): Use when higher voltage margin is required, when YAGEO inventory availability is preferred, or when the application benefits from the High Q feature of the YAGEO component. The 0.90mm maximum thickness must be verified against PCB assembly height constraints.

Both parts maintain identical capacitance, tolerance, temperature coefficient, and operating temperature specifications, ensuring functional equivalence in circuit performance.

Frequently Asked Questions (FAQ)

Q: Can CQ0603BRNPOYBN2R7 be used as a direct replacement for 0603J2002P70BCT?

A: Yes, the CQ0603BRNPOYBN2R7 is functionally equivalent for applications operating at or below 200V. The higher 250V rating provides additional voltage margin. The 0.90mm thickness must be confirmed compatible with your PCB assembly specifications.

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

A: C0G and NP0 are equivalent designations for the same temperature coefficient class, indicating minimal capacitance variation across the -55°C to 125°C operating range. Both parts meet this specification.

Q: Are there any physical compatibility concerns between these parts?

A: Both parts use the 0603 (1608 Metric) package with identical length and width. The thickness difference (0.80mm vs. 0.90mm) must be evaluated against your PCB assembly clearance requirements and solder reflow profile.

Q: Do both parts meet the same compliance standards?

A: Yes, both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings, ensuring equivalent compliance for regulated applications.

Q: What does the ±0.1pF tolerance mean for this 2.7 pF capacitor?

A: The tolerance specifies that the actual capacitance will fall within the range of 2.6 pF to 2.8 pF. Both parts maintain this identical tolerance specification.
