Equivalent & Substitute Parts for 0603J2003P60CUT

Part Overview

The 0603J2003P60CUT is a 3.6 pF ceramic capacitor manufactured by Knowles Syfer, designed for RF and microwave applications requiring high Q, low loss, and ultra-low ESR characteristics. This surface mount multilayer ceramic capacitor (MLCC) operates at 200V rated voltage with C0G/NP0 temperature coefficient, ensuring stable performance across -55°C to 125°C. The part is currently active in production with 641 pieces in stock and maintains full RoHS3 and REACH compliance. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design requirements permit higher voltage ratings or improved tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0603J2003P60CUT is determined by the following critical parameters:

• Capacitance Value: Must be 3.6 pF (exact match required)
• Temperature Coefficient: Must be C0G or NP0 (interchangeable designations for the same characteristic)
• Package / Case: Must be 0603 (1608 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Voltage Rating: Must be equal to or greater than 200V
• Compliance: Must maintain RoHS3 and REACH compliance status

The substitute part CBR06C369BAGAC meets all substitution criteria. It maintains identical capacitance, temperature coefficient, package, and mounting specifications while providing an upgraded voltage rating of 250V and improved tolerance of ±0.1pF compared to the original ±0.25pF specification.

Parameter Comparison

Engineering Selection Recommendations

The CBR06C369BAGAC from KEMET is a direct substitute for the 0603J2003P60CUT. Both parts maintain active production status and full compliance with RoHS3 and REACH regulations. The KEMET substitute provides a higher voltage rating (250V versus 200V) and tighter tolerance specification (±0.1pF versus ±0.25pF), making it suitable for applications where the original part is unavailable. The maximum thickness difference of 0.004" (0.10mm) remains within typical PCB assembly tolerances for 0603 packages. Selection between these parts should be based on availability, lead time, and packaging requirements (the substitute is supplied in Tape & Reel format).

Frequently Asked Questions (FAQ)

Q: Can CBR06C369BAGAC replace 0603J2003P60CUT in all applications?

A: Yes, provided the circuit design does not require the specific lower thickness of the original part. The substitute's 0.035" maximum thickness is within standard 0603 package specifications and compatible with standard PCB assembly processes.

Q: What is the significance of the voltage rating difference (200V vs. 250V)?

A: The higher voltage rating of the substitute part provides additional safety margin in the circuit. A 250V-rated capacitor can be used in applications designed for 200V operation without performance degradation.

Q: Are the tolerance specifications interchangeable?

A: The substitute's ±0.1pF tolerance is tighter than the original ±0.25pF specification. In applications where the original tolerance is acceptable, the substitute will perform equivalently or better. In applications requiring the specific ±0.25pF tolerance, the substitute's tighter tolerance remains compatible.

Q: What packaging format differences exist between these parts?

A: The original part is supplied in standard packaging, while the substitute (CBR06C369BAGAC) is supplied in Tape & Reel (TR) format. Both are suitable for automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.24.0020.
