Substitute Part Grouping Explanation

Substitution relationships are established based on the following criteria:

Upgrade Substitutes — Parts with identical capacitance, voltage rating, and package, but with tighter tolerance specifications (±5% or ±10% versus ±20%). These provide improved circuit performance where tolerance-sensitive applications require higher precision.

Parametric Equivalents — Parts from the same manufacturer series with identical electrical and mechanical specifications but different packaging designations or lead configurations, maintaining full functional interchangeability.

Direct Substitutes — Parts from alternative manufacturers (YAGEO, KEMET) with matching capacitance, voltage, temperature coefficient, and package dimensions. These provide cross-manufacturer compatibility for supply chain flexibility.

Voltage-Upgraded Substitutes — Parts with identical capacitance and tolerance but higher voltage ratings (200V or 250V). These are suitable for applications requiring increased voltage margin while maintaining the same physical footprint.

Manufacturer Recommended Substitutes — Parts from TDK Corporation designated as manufacturer-recommended alternatives, though marked as Not For New Designs status.

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): KGM21AR72A223MU (KYOCERA AVX parametric equivalent) or CC0805MRX7R0BB223 (YAGEO direct substitute) maintain identical electrical performance with 0.022 µF ±20% at 100V. Both are ROHS3 compliant and MSL 1 rated. The YAGEO part offers reduced thickness (1.00mm vs 1.45mm), beneficial for space-constrained layouts.

For Improved Tolerance: KGM21AR72A223JU (±5%) or KGM21AR72A223KL (±10%) from KYOCERA AVX provide tighter tolerance specifications while maintaining 100V rating and Active product status. These are preferred when circuit design requires reduced capacitance variation.

For Cross-Manufacturer Compatibility: CC0805KRX7R0BB223 (YAGEO, ±10%) or C0805C223K1RAC7800 (KEMET, ±10%) offer equivalent performance with established supply chain alternatives. Both maintain Active status and ROHS3 compliance.

For Voltage Margin Applications: C0805C223K2RAC7800 (200V) or C0805C223KARAC7800 (250V) from KEMET provide higher voltage ratings within the same 0805 package footprint, suitable for designs requiring increased voltage headroom.

Not Recommended for New Designs: C2012X7R2A223M125AA (TDK Corporation) is marked Not For New Designs and should be avoided in new product development despite parametric equivalence.

All recommended substitutes are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.

Frequently Asked Questions (FAQ)

Q: Can KGM21AR72A223JU replace KGM21AR72A223ML directly? A: Yes. Both parts share identical capacitance (0.022 µF), voltage rating (100V), temperature coefficient (X7R), and 0805 package. The KGM21AR72A223JU offers tighter ±5% tolerance versus ±20%, making it a direct upgrade with improved precision.

Q: What is the difference between KYOCERA AVX and YAGEO substitutes? A: Both manufacturers produce equivalent 0.022 µF 100V X7R 0805 capacitors meeting the same electrical specifications. YAGEO parts (CC series) typically feature reduced thickness (0.95–1.00mm) compared to KYOCERA AVX (1.45mm), offering space savings in compact designs. All are ROHS3 compliant.

Q: Can I use C0805C223K2RAC7800 (200V) instead of the 100V rated part? A: Yes, for direct substitution. The 200V rating provides additional voltage margin while maintaining identical capacitance, tolerance (±10%), and package dimensions. This is suitable when circuit design permits higher voltage components.

Q: Are all substitute parts in Active product status? A: All recommended substitutes except C2012X7R2A223M125AA (TDK, Not For New Designs) are Active status. Active status ensures ongoing manufacturer support and supply availability.

Q: What does MSL 1 (Unlimited) mean for these capacitors? A: MSL 1 indicates Moisture Sensitivity Level 1, the lowest moisture sensitivity classification. These parts require no special moisture control during storage, handling, or assembly, simplifying logistics and manufacturing processes.

Q: How do tolerance specifications affect circuit performance? A: Tolerance defines the acceptable capacitance range around the nominal value. ±20% allows ±0.0044 µF variation, while ±5% allows ±0.0011 µF. Tighter tolerances (±5% or ±10%) are required for precision filtering, timing, or frequency-critical applications.

Q: Are KEMET C0805C series parts compatible with the 0805 footprint? A: Yes. All KEMET C0805C parts conform to 0805 (2012 Metric) package dimensions (0.079" L × 0.049" W). Reduced thickness (0.035" vs 0.057") may require PCB design verification for clearance in high-density layouts.
