The KYOCERA AVX CC05CX1R2C is a ceramic capacitor designed for through-hole mounting in radial lead configuration. This component serves applications where conventional surface-mount devices may not be suitable due to mechanical stress requirements, repair accessibility, or legacy board compatibility. The radial lead format provides self-supporting mechanical stability and simplifies manual assembly or prototype development workflows.
As a ceramic capacitor, this device utilizes dielectric ceramic materials to achieve capacitive energy storage in a compact form factor. Ceramic capacitors are characterized by low equivalent series resistance, minimal leakage current, and stable performance across varying temperature and frequency conditions. These electrical properties make them suitable for decoupling, filtering, and timing applications in analog and digital circuits. The radial construction allows the component to be mounted perpendicular to the PCB surface, which can be advantageous in high-density layouts or when vertical clearance is less constrained than board area.
The CC05CX1R2C is supplied in bulk packaging, which is commonly specified for high-volume production environments where automated or semi-automated insertion equipment is used. Bulk packaging reduces per-unit cost and simplifies handling in manufacturing lines equipped with radial component feeders. This packaging method is distinct from tape-and-reel or tube formats and is selected based on assembly process requirements and throughput targets.
It should be noted that this component carries a RoHS non-compliant designation, indicating the presence of restricted substances as defined under EU Directive 2011/65/EU. This classification affects product selection for projects requiring full environmental compliance and may limit applicability in certain markets or end-use equipment categories. Design teams working under RoHS mandates should verify regulatory alignment during component qualification phases.
The device is classified under ECCN code EAR99, which represents items subject to U.S. Export Administration Regulations but not specifically controlled beyond standard commercial terms. The HTSUS classification 8532.24.0060 corresponds to ceramic dielectric fixed capacitors for international trade and customs purposes.
With 1169 pieces available as new original stock, the CC05CX1R2C supports both prototype evaluation and production procurement requirements. The component's active product status from KYOCERA AVX indicates ongoing manufacturing support and supply chain availability, which contributes to long-term design stability and reduces obsolescence risk in multi-year production cycles.
Replacement Planning for KYOCERA AVX CC05CX1R2C Radial Ceramic Capacitors
When KYOCERA AVX CC05CX1R2C becomes difficult to source, reaches end-of-life risk in a bill of materials, or creates compliance concerns because of its RoHS non-compliant status, selecting a replacement is not just a matter of matching capacitance. A practical equivalent must be checked against dielectric behavior, capacitance tolerance, voltage rating, lead spacing, body size, RF behavior, soldering process, qualification needs, and long-term availability.
For CC05CX1R2C replacement evaluation, commonly considered alternative part numbers include:
| Manufacturer | Candidate Part Number |
|---|---|
| KYOCERA AVX | SR151A1R2CAA |
| KEMET | C315C1R2C5G5TA |
| Murata | RCE5C1H1R2C0A2H03B |
| TDK | FG18C0G1H1R2CNT06 |
| Vishay | K120J15C0GF5TH5 |
These parts are not automatically drop-in replacements in every design. They should be evaluated as radial leaded ceramic capacitor alternatives for CC05CX1R2C, especially where the original component is used in RF tuning, timing, impedance compensation, filtering, or low-capacitance coupling circuits.
What KYOCERA AVX CC05CX1R2C Means in the Original Circuit
KYOCERA AVX CC05CX1R2C is identified as a radial leaded ceramic capacitor supplied in bulk packaging. The available product data indicates an active product status, EAR99 classification, HTSUS 8532.24.0060, and RoHS non-compliant status. The capacitance code “1R2” typically indicates 1.2 pF, while the “C” tolerance code is commonly associated with tight low-pF tolerance such as ±0.25 pF, depending on the exact KYOCERA AVX series coding.
| Parameter | CC05CX1R2C Engineering Relevance |
|---|---|
| Manufacturer | KYOCERA AVX |
| Component type | Radial leaded ceramic capacitor |
| Nominal capacitance | Typically interpreted as 1.2 pF from “1R2” code |
| Tolerance class | Likely tight tolerance; confirm against original datasheet or drawing |
| Mounting style | Through-hole radial |
| Packaging | Bulk |
| Compliance status | RoHS non-compliant |
| MSL | Not applicable |
| Product status | Active |
| Inventory reference | 1169 pcs new original in stock |
Because CC05CX1R2C is a very low-capacitance ceramic capacitor, parasitic effects can become comparable to the nominal capacitance. Lead length, lead pitch, pad geometry, and board layout may shift circuit behavior more than expected. In RF networks, oscillator tanks, impedance matching, detector circuits, or high-frequency compensation paths, replacing CC05CX1R2C with a physically different capacitor can alter resonance, insertion loss, Q factor, or phase response.
The RoHS non-compliant status also affects replacement decisions. Legacy equipment may require exact material compatibility, while new production often requires a RoHS-compliant equivalent. If the capacitor is used in repair work, an original CC05CX1R2C may be preferred. If it is used in new manufacturing, a RoHS-compliant radial ceramic capacitor with matching capacitance, tolerance, dielectric, voltage rating, and lead spacing is usually the more practical choice.
Candidate Equivalent Parts for KYOCERA AVX CC05CX1R2C Replacement
The following table compares practical candidate replacements for KYOCERA AVX CC05CX1R2C. The listed alternatives are selected around the likely 1.2 pF radial ceramic capacitor requirement, but each candidate should be validated against the original schematic, PCB footprint, voltage stress, and environmental requirements.
| Manufacturer | Part Number | Key Specifications | Product Features | Typical Applications | Why It Can Replace the Original Part | Main Differences or Limitations | Recommended Usage |
|---|---|---|---|---|---|---|---|
| KYOCERA AVX | SR151A1R2CAA | 1.2 pF class radial ceramic capacitor, C0G/NP0-type dielectric, tight tolerance class, through-hole radial format | Stable low-capacitance ceramic construction, low temperature coefficient, suitable for precision circuits | RF tuning, impedance matching, timing compensation, low-level signal coupling | Same manufacturer ecosystem as CC05CX1R2C and similar radial ceramic capacitor function | Exact package dimensions, voltage rating, and lead spacing must be confirmed against CC05CX1R2C | Preferred first-choice alternative when maintaining KYOCERA AVX sourcing consistency |
| KEMET | C315C1R2C5G5TA | 1.2 pF radial leaded ceramic capacitor, C0G/NP0 dielectric, tight tolerance, typically 50 V class depending on suffix | Good capacitance stability, low loss, established radial ceramic capacitor family | RF filters, oscillators, timing circuits, instrumentation | Matches the low-pF ceramic capacitor function and stable dielectric behavior needed for CC05CX1R2C substitution | Body style and lead configuration may differ from KYOCERA AVX CC05 package | Suitable when stable electrical behavior is more important than exact mechanical duplication |
| Murata | RCE5C1H1R2C0A2H03B | 1.2 pF radial monolithic ceramic capacitor, C0G/NP0 class, 50 V class indicated by “1H” code, tight tolerance coding | Compact radial MLCC construction, stable temperature behavior, RoHS-oriented supply options | RF coupling, resonance adjustment, high-frequency bypass in low-capacitance nodes | Provides similar capacitance value and stable dielectric characteristics for low-pF replacement | Mechanical footprint and lead forming may require PCB fit verification | Good choice for designs requiring modern supply availability and stable C0G performance |
| TDK | FG18C0G1H1R2CNT06 | 1.2 pF radial leaded MLCC, C0G dielectric, 50 V class, tight tolerance class depending on suffix | Low-loss dielectric, radial leaded format, suitable for high-frequency circuits | RF modules, filters, signal conditioning, oscillator support networks | C0G dielectric and 1.2 pF capacitance make it a practical electrical alternative to CC05CX1R2C | Lead pitch and body size may not match the original KYOCERA AVX part exactly | Recommended where C0G stability and broad component availability are priorities |
| Vishay | K120J15C0GF5TH5 | 1.2 pF class radial ceramic capacitor, C0G/NP0-type dielectric option, through-hole construction | Low capacitance ceramic device, stable dielectric option, radial mounting | RF trimming networks, tuned circuits, low-capacitance coupling | Can serve the same circuit role if capacitance, tolerance, voltage, and footprint are confirmed | Part-family coding must be checked carefully because suffixes affect tolerance, voltage, and packaging | Use when Vishay sourcing is preferred and mechanical validation is completed |
For an electrical equivalent to CC05CX1R2C, the strongest matching factors are capacitance value, dielectric class, and tolerance. In a 1.2 pF circuit position, X7R or general-purpose high-K dielectrics are usually poor substitutes because capacitance shift with voltage, temperature, and aging can exceed the intended tuning margin. C0G/NP0-type dielectric candidates such as SR151A1R2CAA, C315C1R2C5G5TA, RCE5C1H1R2C0A2H03B, FG18C0G1H1R2CNT06, and K120J15C0GF5TH5 are more appropriate for precision and RF-sensitive applications.
Mechanical compatibility should be checked before approving any substitute. A radial capacitor that is electrically suitable may still require lead forming, PCB pad adjustment, or body clearance review. This is especially relevant in older boards where CC05CX1R2C may have been selected for a specific radial lead pitch or coated body profile.
