Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Capacitance value: 3 pF (exact match required)
• Temperature coefficient: C0G or NP0 (functionally equivalent designations)
• Package / Case: 0201 (0603 Metric) (mechanical and footprint compatibility)
• Mounting type: Surface Mount, MLCC
• Operating temperature range: -55°C to 125°C (minimum requirement)
• RoHS3 compliance and MSL 1 rating (regulatory and environmental compatibility)

Secondary Tolerance Consideration:

• Tolerance of ±0.25pF is the baseline specification for the main part
• Parts with tighter tolerance (±0.1pF) are classified as upgrades and are fully substitutable
• Tolerance is not a limiting factor for substitution; tighter tolerances represent enhanced performance

Voltage Rating Consideration:

• The main part is rated at 25V
• Parts rated at 25V are direct equivalents
• Parts rated at 50V are upgrades and are fully substitutable (higher voltage rating provides additional design margin)

All substitute parts listed meet or exceed the electrical and mechanical requirements of CBR02C309C3GAC.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and active product status. Selection should be based on procurement availability, lead time requirements, and application-specific tolerance or voltage margin needs.

Frequently Asked Questions (FAQ)

Q: Can GJM0335C1E3R0CB01D replace CBR02C309C3GAC directly? A: Yes. GJM0335C1E3R0CB01D is a direct equivalent with identical capacitance (3 pF), tolerance (±0.25pF), voltage rating (25V), temperature coefficient (C0G/NP0), package (0201), and physical dimensions. No circuit modifications are required.

Q: What is the difference between the KEMET CBR02C309B3GAC and the main part CBR02C309C3GAC? A: Both parts are identical except for tolerance. CBR02C309B3GAC offers tighter tolerance (±0.1pF) compared to CBR02C309C3GAC (±0.25pF). This makes CBR02C309B3GAC suitable for applications requiring improved capacitance accuracy and stability.

Q: Is GJM0335C1H3R0BB01D compatible with a 25V circuit design? A: Yes. GJM0335C1H3R0BB01D is rated at 50V, which exceeds the 25V requirement. Higher voltage rating provides additional safety margin and is fully compatible with 25V circuit designs. This part is suitable for applications where future voltage margin or design flexibility is beneficial.

Q: Are all substitute parts available in the same packaging format? A: All substitute parts use 0201 (0603 Metric) package with identical physical dimensions (0.60mm × 0.30mm × 0.33mm max thickness). Packaging formats differ: CBR02C309C3GAC and GJM0335C1H3R0BB01D are supplied in Tape & Reel (TR); CBR02C309B3GAC is supplied in Tape & Reel (TR); GJM0335C1E3R0CB01D and GJM0335C1E3R0BB01D are supplied in Cut Tape (CT) & Digi-Reel®; QLCD250Q3R0C1GV001T is supplied in Cut Tape (CT).
