CBR02C309C9GAC Equivalent & Substitute Parts

Part Overview

The CBR02C309C9GAC is a 3 pF ceramic capacitor manufactured by KEMET, rated at 6.3V with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) is designed for RF, microwave, and high-frequency applications requiring high Q factor and ultra-low ESR performance. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the original specification requires higher voltage ratings, improved tolerance specifications, or alternative manufacturer sourcing for supply chain optimization while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CBR02C309C9GAC is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Capacitance value: 3 pF (exact match required)
• Temperature coefficient: C0G/NP0 (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Package / Case: 0201 (0603 Metric) (exact match required)
• Physical dimensions: 0.024" L x 0.012" W, 0.013" max thickness (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)

Allowable Variation Parameters:

• Voltage rating: May be equal to or higher than 6.3V
• Tolerance: May be equal to or tighter than ±0.25pF
• Manufacturer: Alternative qualified manufacturers permitted
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) formats acceptable

All substitute parts listed maintain identical electrical performance at the original 6.3V specification while offering enhanced voltage margin or improved tolerance characteristics. Substitutes are sourced from KEMET and Murata Electronics, both manufacturers with active product status and full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the CBR02C309C9GAC within the specified application parameters. Selection among substitutes is based on the following criteria:

KEMET CBR02C309B3GAC: Direct manufacturer upgrade within the same CBR-SMD RF C0G series. Provides 25V voltage rating with improved ±0.1pF tolerance. Recommended for applications requiring higher voltage margin while maintaining KEMET supply chain continuity. Active product status with full RoHS3 compliance.

Murata GJM0335C1E3R0BB01D: Murata equivalent with 25V rating and ±0.1pF tolerance. Highest inventory availability (238,835 pcs) among all substitutes. Suitable for high-volume production requirements. Cut Tape & Digi-Reel packaging format. Active product status with full RoHS3 compliance.

Murata GJM0335C1E3R0CB01D: Murata equivalent with 25V rating and ±0.25pF tolerance matching the original specification. Lower inventory availability (2,400 pcs). Cut Tape & Digi-Reel packaging format. Active product status with full RoHS3 compliance.

Murata GJM0335C1H3R0BB01D: Murata equivalent with highest voltage rating (50V) and ±0.1pF tolerance. Provides maximum voltage margin for demanding applications. Tape & Reel packaging. Inventory availability of 45,275 pcs. Active product status with full RoHS3 compliance.

Johanson Technology QLCD250Q3R0C1GV001T: Alternative manufacturer option with 25V rating and ±0.25pF tolerance. High inventory availability (58,680 pcs). Cut Tape packaging format. Active product status with full RoHS3 compliance.

All substitutes carry identical ECCN (EAR99), HTSUS (8532.24.0020), REACH Unaffected, and MSL 1 (Unlimited) designations as the original part.

Frequently Asked Questions (FAQ)

Q: Can CBR02C309B3GAC be used as a direct replacement for CBR02C309C9GAC?

A: Yes. The CBR02C309B3GAC is a direct substitute with identical capacitance (3 pF), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), and package dimensions (0201/0603 Metric). The 25V rating exceeds the original 6.3V specification, and the ±0.1pF tolerance is tighter than the original ±0.25pF specification. Both parameters are allowable variations for substitution.

Q: What is the difference between the Murata GJM0335C1E3R0BB01D and GJM0335C1E3R0CB01D?

A: Both parts are Murata GJM series equivalents with identical 3 pF capacitance, 25V voltage rating, C0G/NP0 temperature coefficient, and 0201 package. The primary difference is tolerance: GJM0335C1E3R0BB01D specifies ±0.1pF tolerance, while GJM0335C1E3R0CB01D specifies ±0.25pF tolerance (matching the original part). Selection depends on tolerance requirements for the application.

Q: Why would I select the GJM0335C1H3R0BB01D with 50V rating over the 25V alternatives?

A: The GJM0335C1H3R0BB01D provides the highest voltage margin (50V) among all substitutes. This selection is appropriate for applications requiring enhanced voltage headroom, improved reliability under transient voltage conditions, or design flexibility for future voltage specification changes. All other electrical parameters remain identical to lower-voltage alternatives.

Q: Are all substitute parts available in the same packaging formats as the original?

A: The original CBR02C309C9GAC is supplied in Tape & Reel (TR) format. Substitute parts are available in either Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel formats. Both packaging formats are suitable for automated assembly processes. Verify packaging format requirements with your procurement specification before final selection.

Q: Do all substitute parts meet the same regulatory and compliance standards as the original?

A: Yes. All listed substitute parts carry identical RoHS3 compliance, REACH Unaffected status, ECCN (EAR99), HTSUS (8532.24.0020), and MSL 1 (Unlimited) ratings as the original CBR02C309C9GAC. No additional compliance verification is required for substitution.

Q: Can I mix manufacturers (KEMET, Murata, Johanson) within the same assembly?

A: Yes. All substitute parts meet identical electrical specifications, mechanical dimensions, and regulatory requirements. Multi-source procurement from KEMET, Murata Electronics, and Johanson Technology is permissible within the same assembly, provided design documentation reflects the approved substitute list.

Q: What is the inventory status for each substitute part?

A: Current inventory levels are: CBR02C309B3GAC (24,643 pcs), GJM0335C1E3R0BB01D (238,835 pcs), GJM0335C1E3R0CB01D (2,400 pcs), GJM0335C1H3R0BB01D (45,275 pcs), and QLCD250Q3R0C1GV001T (58,680 pcs). Inventory levels are subject to change; verify current availability with your component supplier.
