0603J2001P10BUT Equivalent & Substitute Parts

Part Overview

The 0603J2001P10BUT is a 1.1 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 MLCC operates across -55°C to 125°C with C0G/NP0 temperature stability and 200V rated voltage. The part is currently active in production with 1138 units in stock. Substitute parts are identified to provide design flexibility when the primary part is unavailable or when design requirements permit higher voltage ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0603J2001P10BUT is determined by the following critical parameters:

Capacitance value must match exactly at 1.1 pF with tolerance of ±0.1pF. Temperature coefficient must be C0G or NP0 to ensure frequency stability across the operating temperature range of -55°C to 125°C. Package and case must be 0603 (1608 Metric) for mechanical and electrical compatibility with existing PCB layouts. Mounting type must be surface mount MLCC. Voltage rating may exceed the 200V specification without compromising functionality, as higher voltage-rated components operate safely at lower applied voltages. Physical dimensions must remain within the specified footprint to ensure assembly compatibility.

The identified substitute CBR06C119BAGAC from KEMET meets all mandatory substitution criteria while providing an elevated 250V voltage rating, offering enhanced design margin in high-voltage applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 0603J2001P10BUT and CBR06C119BAGAC are active production parts with full ROHS3 compliance and unlimited moisture sensitivity rating. The primary distinction is the voltage rating differential: the KEMET substitute provides 250V versus the Knowles Syfer original at 200V. This 50V margin increase does not alter electrical performance at the specified operating voltage and may provide additional design margin in applications approaching the 200V limit. Both parts maintain identical capacitance, tolerance, temperature coefficient, and thermal operating range. The thickness differential of 0.005" (0.10mm) between parts is negligible for standard PCB assembly processes. Selection between these parts should be based on supply chain availability, cost considerations, and specific application voltage requirements.

Frequently Asked Questions (FAQ)

Q: Can CBR06C119BAGAC replace 0603J2001P10BUT in all applications? A: Yes, provided the application operates at or below 200V. The substitute's 250V rating is compatible with all circuits designed for the original 200V specification.

Q: Are the physical dimensions identical between these parts? A: The length and width are identical at 0.063" x 0.031" (1.60mm x 0.80mm). The thickness differs by 0.005" (0.10mm), with the KEMET part at 0.035" maximum versus 0.031" for the Knowles Syfer part. This difference is within standard PCB assembly tolerances.

Q: Do both parts have the same temperature stability? A: Yes. Both employ C0G/NP0 temperature coefficient and operate across -55°C to 125°C with identical frequency stability characteristics.

Q: What is the significance of the ±0.1pF tolerance? A: This tight tolerance ensures precise capacitance values critical for RF and microwave circuit tuning and impedance matching applications.

Q: Are packaging differences between these parts significant? A: The original ships in standard packaging while the substitute is supplied in Tape & Reel format. Both are suitable for automated assembly; tape and reel packaging is standard for high-volume production environments.

Q: Can these parts be used interchangeably on the same PCB? A: Yes. Both parts share identical footprints and mounting requirements for 0603 (1608 Metric) surface mount assembly.
