CBR02C109C8GAC Equivalent & Substitute Parts

Part Overview

The CBR02C109C8GAC is a 1 pF ceramic capacitor manufactured by KEMET, designed for RF and microwave applications requiring high Q and ultra-low ESR characteristics. This C0G/NP0 temperature coefficient capacitor operates across -55°C to 125°C with a rated voltage of 10V and tolerance of ±0.25pF. The part is actively produced and ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection. Substitute parts are identified for applications requiring higher voltage ratings, improved tolerance specifications, or alternative packaging formats while maintaining electrical compatibility in RF circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria applied strictly to the provided parameters:

Mandatory Matching Parameters:

• Capacitance value: 1 pF (exact match required)
• Temperature Coefficient: C0G/NP0 (exact match required)
• Package/Case: 0201 (0603 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Acceptable Upgrade Parameters:

• Voltage Rating: May exceed 10V (higher ratings provide additional safety margin)
• Tolerance: May be tighter than ±0.25pF (improved precision is acceptable)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats are interchangeable

All four substitute parts meet these criteria and are classified as direct electrical equivalents with enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are electrically and mechanically compatible with the CBR02C109C8GAC based on provided specifications. Selection among substitutes depends on application-specific requirements:

CBR02C109B3GAC (KEMET): Maintains manufacturer continuity with KEMET while providing 25V voltage rating and improved ±0.1pF tolerance. Suitable for designs requiring single-source qualification or KEMET-specific supply chain requirements.

GJM0335C1E1R0CB01D (Murata Electronics): Provides 25V rating with ±0.25pF tolerance matching the original specification. Tape & Reel packaging maintains original format compatibility.

GJM0335C1E1R0WB01D (Murata Electronics): Offers 25V rating with superior ±0.05pF tolerance for applications requiring enhanced frequency stability. Cut Tape & Digi-Reel® packaging provides alternative supply format.

GJM0335C1H1R0WB01D (Murata Electronics): Delivers highest voltage rating at 50V with ±0.05pF tolerance for maximum design margin and precision. Suitable for applications with elevated voltage stress or future design upgrades.

All parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status. Product status is active for all options, ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can CBR02C109B3GAC replace CBR02C109C8GAC in all applications?

A: Yes. CBR02C109B3GAC is electrically and mechanically compatible. The 25V rating exceeds the 10V requirement, and ±0.1pF tolerance is tighter than the original ±0.25pF specification. Both parts share identical capacitance, temperature coefficient, package dimensions, and operating temperature range.

Q: What is the difference between KEMET and Murata substitute options?

A: KEMET CBR02C109B3GAC maintains manufacturer continuity. Murata GJM series parts provide equivalent electrical performance with different tolerance grades and voltage ratings. All meet identical compliance and MSL requirements. Selection depends on supply chain, qualification, or performance requirements.

Q: Are the Murata GJM parts with ±0.05pF tolerance necessary for RF applications?

A: Tolerance selection depends on circuit requirements. GJM0335C1E1R0WB01D and GJM0335C1H1R0WB01D offer ±0.05pF tolerance for applications requiring tighter frequency control. The original ±0.25pF tolerance is acceptable for many RF designs; tighter tolerance provides additional margin for frequency-critical circuits.

Q: Can packaging format be changed between Tape & Reel and Cut Tape?

A: Yes. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats are interchangeable for the same electrical part. Format selection depends on assembly equipment and volume requirements. All substitute parts maintain identical 0201 (0603 Metric) package dimensions.

Q: What voltage rating should be selected for new designs?

A: Selection depends on circuit voltage stress. The original 10V rating is minimum for the specified application. CBR02C109B3GAC and GJM0335C1E1R0CB01D/WB01D provide 25V rating. GJM0335C1H1R0WB01D provides 50V rating for maximum design margin. Higher ratings do not affect electrical performance in 10V applications.

Q: Are all parts suitable for high-frequency RF and microwave applications?

A: Yes. All parts are specified for RF and microwave applications with high Q and low loss characteristics. C0G/NP0 temperature coefficient ensures frequency stability across -55°C to 125°C operating range. Electrical performance is equivalent across all options.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Unlimited) indicates the component requires no moisture sensitivity protection during storage or handling. All parts share this rating, eliminating moisture-related reliability concerns for both original and substitute parts.
