0603J2002P40CUT Equivalent & Substitute Parts

Part Overview

The 0603J2002P40CUT is a 2.4 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 a rated voltage of 200V and C0G/NP0 temperature coefficient. The part is currently active in production with 647 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, lead time considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0603J2002P40CUT is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 2.4 pF
• Temperature coefficient: C0G/NP0
• Package / Case: 0603 (1608 Metric)
• Mounting type: Surface Mount, MLCC
• Operating temperature range: -55°C ~ 125°C
• Applications: RF, Microwave, High Frequency

Allowable Variations:

• Voltage rating: Equal to or greater than 200V
• Tolerance: Equal to or tighter than ±0.25pF
• Physical dimensions: Within 0603 package specifications
• Compliance certifications: ROHS3 and REACH status maintained

The CBR06C249BAGAC from KEMET meets all mandatory matching criteria and exceeds performance specifications in voltage rating (250V vs. 200V) and tolerance (±0.1pF vs. ±0.25pF), making it a direct electrical and mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

The CBR06C249BAGAC is a qualified substitute for the 0603J2002P40CUT based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical capacitance (2.4 pF), temperature coefficient (C0G/NP0), and operating temperature range (-55°C ~ 125°C). The substitute's higher voltage rating (250V) and tighter tolerance (±0.1pF) provide enhanced performance margins without compromising circuit design requirements.

Mechanical Compatibility: Both parts conform to the 0603 (1608 Metric) package standard with identical length and width dimensions (1.60mm x 0.80mm). The substitute's maximum thickness of 0.90mm remains within acceptable PCB assembly tolerances for 0603 components.

Compliance & Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for production and distribution. Moisture sensitivity level 1 (unlimited) is identical across both parts, eliminating special handling requirements.

Product Status: Both parts are active in production with confirmed inventory availability, supporting immediate design implementation and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the CBR06C249BAGAC replace the 0603J2002P40CUT in RF and microwave circuits?

A: Yes. Both parts are rated for RF and microwave applications with identical high Q, low loss, and ultra-low ESR characteristics. The substitute's higher voltage rating and tighter tolerance provide equivalent or superior performance in these applications.

Q: Are there any physical compatibility issues with the substitute part?

A: No. Both parts use the 0603 (1608 Metric) package with identical length and width (1.60mm x 0.80mm). The substitute's maximum thickness of 0.90mm is within standard PCB assembly tolerances for this package class and does not affect placement or reflow processes.

Q: Do both parts require identical handling and storage procedures?

A: Yes. Both parts have moisture sensitivity level 1 (unlimited), eliminating special moisture control requirements during storage, handling, or assembly.

Q: What is the tolerance difference between these parts?

A: The original part has ±0.25pF tolerance, while the substitute has ±0.1pF tolerance. The tighter tolerance of the substitute provides improved capacitance accuracy without affecting circuit compatibility.

Q: Are regulatory certifications identical?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status for production and distribution.

Q: What voltage margin does the substitute provide?

A: The substitute is rated for 250V compared to the original part's 200V rating, providing a 50V safety margin for applications operating at or near the original 200V specification.
