The KYOCERA AVX SR215E223ZAATR1 is a 0.022 µF ceramic capacitor designed for general-purpose circuit applications requiring through-hole mounting and Class II dielectric characteristics. This component belongs to the SkyCap® SR series and combines a compact radial package with Z5U temperature coefficient performance across a 10°C to 85°C operating range.
With a voltage rating of 50V and a tolerance range of -20% to +80%, this capacitor addresses applications where moderate capacitance stability is acceptable in exchange for higher volumetric efficiency. The Z5U dielectric formulation provides predictable capacitance variation under temperature cycling, making it suitable for coupling, decoupling, and bulk energy storage in cost-sensitive designs where tight tolerance control is not the primary constraint.
The radial form factor measures 0.200" L x 0.125" W (5.08mm x 3.18mm) with a maximum seated height of 0.300" (7.62mm) and features formed kinked leads at 0.200" pitch, facilitating reliable PCB insertion and mechanical stability during wave soldering or manual assembly processes. This lead configuration improves board retention and reduces the risk of component displacement during handling or thermal stress.
Supplied in tape and reel packaging, the SR215E223ZAATR1 supports automated pick-and-place workflows in medium to high-volume production environments. The component meets RoHS3 compliance requirements and carries an EAR99 ECCN classification, simplifying integration into globally distributed supply chains and export-controlled product lines.
Engineers selecting this capacitor typically prioritize cost-effective board-level capacitance in power supply filtering, AC line bypassing, or non-critical timing networks where the wide tolerance band and Z5U temperature behavior align with circuit performance margins. The active product status and availability in original factory packaging ensure design longevity and traceability for both prototyping and production phases.

Replacement Planning for KYOCERA AVX SR215E223ZAATR1 0.022 µF 50 V Radial Ceramic Capacitor
When replacing KYOCERA AVX SR215E223ZAATR1, the main challenge is not only matching the nominal capacitance and voltage rating, but also confirming dielectric behavior, lead spacing, board fit, tolerance range, and long-term availability. This part is a 0.022 µF 50 V Z5U radial ceramic capacitor used in general-purpose through-hole circuits, so replacement selection should account for capacitance shift over temperature, DC bias behavior, and whether the circuit can tolerate the wide Z5U tolerance of -20%, +80%.

What Defines KYOCERA AVX SR215E223ZAATR1 as the Original Design Reference
KYOCERA AVX SR215E223ZAATR1 is part of the SkyCap® SR radial ceramic capacitor family. Its main electrical value is 0.022 µF, also written as 22 nF, with a 50 V rated voltage. The original dielectric is Z5U, with a tolerance of -20%, +80%, and an operating temperature range of 10°C to 85°C.
From a replacement perspective, the Z5U dielectric is the most influential characteristic. Z5U capacitors provide compact capacitance at low cost, but capacitance varies significantly with temperature, voltage, and aging. In timing, filtering, coupling, bypass, or non-precision general-purpose circuits, this may be acceptable. In frequency-sensitive, analog accuracy, or temperature-variable environments, a more stable dielectric such as X7R may be a better alternative.
Mechanically, SR215E223ZAATR1 uses a radial through-hole package with 5.08 mm lead spacing, formed kinked leads, an approximate body size of 5.08 mm x 3.18 mm, and a seated height up to 7.62 mm. These details affect whether a substitute will fit without changing PCB hole spacing, insertion height, or assembly process.
Typical applications include general-purpose decoupling, low-frequency bypassing, noise suppression, and signal coupling where tight capacitance accuracy is not the main design constraint. For replacement evaluation, the original part should be treated as a 22 nF, 50 V, radial-leaded ceramic capacitor with relaxed capacitance tolerance and standard through-hole assembly requirements.

Engineering Trade-Offs When Selecting SR215E223ZAATR1 Replacement Options
Replacement selection should balance electrical equivalence, mechanical fit, dielectric behavior, sourcing risk, and assembly compatibility. A part with the same capacitance and voltage rating may still behave differently in the circuit if the dielectric changes from Z5U to X7R.
| Replacement Option | Electrical Compatibility | Mechanical Compatibility | Performance Differences | Reliability and Stability | Package Availability | Cost Considerations | Suitable Application Scenarios | Advantages | Limitations |
|---|---|---|---|---|---|---|---|---|---|
| KYOCERA AVX SR215C223KARTR1 | High for capacitance and voltage; dielectric may differ from SR215E223ZAATR1 | Potentially strong because it is from the same manufacturer and similar radial family | More stable than Z5U if X7R version is used | Better capacitance retention over temperature than Z5U | Depends on current SkyCap availability and suffix | May cost slightly more than basic Z5U parts | General-purpose circuits needing same-brand continuity | Same-brand sourcing path and improved stability | Must verify exact tolerance, lead spacing, and lead style |
| KEMET C315C223M5U5TA | Strong match for 22 nF, 50 V, and Z5U behavior | Good if lead spacing and body height fit the original PCB | Closest dielectric behavior to the original among listed candidates | Similar Z5U aging and temperature variation | Common radial ceramic format | Often cost-effective for general-purpose replacement | Non-precision bypass, coupling, consumer or legacy boards | Maintains similar electrical behavior to SR215E223ZAATR1 | Less stable than X7R alternatives |
| TDK FG28X7R1H223KNT06 | Strong for nominal capacitance and voltage; dielectric upgrade from Z5U | Must confirm lead pitch, case size, and insertion height | Lower capacitance drift across temperature than Z5U | Good stability for control and industrial circuits | Availability depends on TDK leaded MLCC stock | May be higher than Z5U options | Decoupling and filtering where stable capacitance is preferred | Better predictable performance across operating range | Not an exact dielectric equivalent |
| Murata RCE5C1H223J0K1H03B | Good if exact capacitance, voltage, and dielectric code match design needs | Requires PCB footprint verification | Can improve consistency depending on dielectric and tolerance | Suitable for applications needing controlled MLCC performance | Murata leaded ceramic availability should be checked | Pricing depends on stock and packaging | Control boards, instrumentation support, general filtering | Strong manufacturer reputation and MLCC process control | Exact replacement suitability depends on datasheet confirmation |
| Vishay K223K15X7RF5TH5 | Good 22 nF, 50 V class compatibility with X7R behavior | Lead spacing and formed lead style must be checked | More stable than original Z5U across temperature | Good general-purpose reliability | Availability varies by package and lead configuration | May be moderate versus commodity Z5U capacitors | Bypass and coupling circuits where X7R is acceptable | Stable dielectric and radial ceramic format | Not a direct Z5U behavioral match |
If the circuit is a legacy design where capacitance tolerance is broad and original behavior should be preserved, a Z5U candidate such as KEMET
C315C223M5U5TA
is often the safer electrical match. If the circuit benefits from tighter capacitance control, lower temperature drift, or improved predictability, X7R-based options such as KYOCERA AVX
