Substitute Part Grouping Explanation

Substitution logic for the P10R223K5 is based on strict equivalence across all critical electrical and mechanical parameters. The following grouping categories apply:

Direct Equivalents (X7R Temperature Coefficient, ±10% Tolerance): Direct substitutes maintain identical capacitance (0.022 µF), voltage rating (50V), tolerance (±10%), and temperature coefficient (X7R). These parts are interchangeable at the circuit level with no performance deviation. All direct equivalents feature the same axial through-hole configuration and operating temperature range (-55°C ~ 125°C).

Tighter Tolerance Variants (X7R Temperature Coefficient, ±5% Tolerance): Parts with ±5% tolerance provide improved capacitance accuracy while maintaining all other electrical specifications. These are functionally compatible substitutes offering enhanced precision for applications requiring tighter component tolerances.

Upgraded Alternatives (C0G/NP0 Temperature Coefficient): C0G (NP0) temperature coefficient variants provide superior temperature stability compared to X7R. These upgrades maintain 0.022 µF capacitance and 50V rating but offer lower capacitance drift across the operating temperature range. Voltage-rated upgrades (100V) provide additional design margin while maintaining the same capacitance value.

Critical Substitution Parameters:

Capacitance: 0.022 µF (exact match required)
Voltage Rating: 50V minimum (100V acceptable as upgrade)
Temperature Coefficient: X7R (or C0G/NP0 for upgraded performance)
Mounting: Through Hole Axial (form factor must match)
Size: 0.100" Dia x 0.170" L or compatible axial dimensions
Operating Temperature: -55°C ~ 125°C minimum

Engineering Selection Recommendations

Primary Direct Substitutes (Identical Electrical Performance):

SA105C223KAA and SA105C223KAA-LF are the preferred direct replacements for P10R223K5. Both parts are manufactured by KYOCERA AVX, maintain identical capacitance (0.022 µF), voltage rating (50V), tolerance (±10%), and temperature coefficient (X7R). These components feature active product status, ensuring long-term availability and supply chain stability. SA105C223KAA-LF carries ROHS3 compliance, meeting modern environmental and regulatory requirements. The physical dimensions (0.100" Dia x 0.170" L) are identical, ensuring direct PCB layout compatibility.

Compliance-Driven Selection:

For applications requiring RoHS3 compliance, SA105C223KAA, SA105C223KAA-LF, and all KEMET C410C and C420C variants are compliant alternatives. The original P10R223K5 is RoHS non-compliant; migration to compliant substitutes is necessary for new designs and regulated applications.

Tighter Tolerance Alternative:

SA105C223JAA provides ±5% tolerance while maintaining all other electrical specifications. This variant is suitable for applications requiring improved capacitance accuracy without performance upgrades.

Upgraded Performance Options:

KEMET C410C series (C410C223F5G5TA, C410C223G5G5TA, C410C223J5G5TA, C410C223K5G5TA) offer C0G (NP0) temperature coefficient with superior temperature stability. These upgrades maintain 50V rating and 0.022 µF capacitance across multiple tolerance grades (±1%, ±2%, ±5%, ±10%). Physical dimensions are slightly reduced (0.095" Dia x 0.170" L), requiring PCB layout verification.

Voltage-Rated Upgrade:

C420C223F1G5TA provides 100V rating with ±1% tolerance and C0G temperature coefficient. This upgrade is suitable for applications requiring additional voltage margin or enhanced temperature stability. Physical dimensions increase to 0.100" Dia x 0.200" L, requiring board space verification.

Frequently Asked Questions (FAQ)

Q: Can SA105C223KAA directly replace P10R223K5 without circuit modification?

A: Yes. SA105C223KAA maintains identical capacitance (0.022 µF), voltage rating (50V), tolerance (±10%), temperature coefficient (X7R), and operating temperature range (-55°C ~ 125°C). Physical dimensions and axial lead configuration are identical. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between X7R and C0G temperature coefficients?

A: X7R provides ±15% capacitance change across the -55°C ~ 125°C operating range. C0G (NP0) provides ±30 ppm/°C, resulting in significantly lower capacitance drift. C0G variants are upgrades offering superior temperature stability for precision applications.

Q: Are KEMET C410C series parts physically compatible with the original P10R223K5?

A: C410C series parts have slightly reduced diameter (0.095" vs. 0.100") but maintain the same length (0.170"). PCB hole spacing and lead insertion compatibility must be verified. The reduced diameter may allow use in tighter board layouts but requires confirmation that existing PCB holes accommodate the smaller lead diameter.

Q: Why is RoHS3 compliance important for substitution?

A: RoHS3 compliance indicates the part meets current environmental and regulatory standards for hazardous substance restrictions. The original P10R223K5 is RoHS non-compliant. New designs and regulated applications require compliant alternatives such as SA105C223KAA or KEMET C410C/C420C series.

Q: Can I use C420C223F1G5TA (100V) in place of P10R223K5 (50V)?

A: Yes, from an electrical standpoint. The 100V rating provides additional voltage margin and is backward-compatible with 50V circuits. However, physical dimensions increase to 0.100" Dia x 0.200" L (vs. 0.170" L original). PCB layout space must accommodate the longer axial length.

Q: What packaging options are available for substitutes?

A: KYOCERA AVX SA105C223KAA is available in Tape & Reel (TR) for automated assembly. SA105C223KAA-LF is available in Bulk. KEMET C410C and C420C series are available in Bulk. Packaging selection depends on assembly process requirements and order quantities.

Q: Are all substitute parts in active production status?

A: Yes. All listed substitutes (KYOCERA AVX SA105C series and KEMET C410C/C420C series) are active products with confirmed ongoing availability. The original P10R223K5 is obsolete, making active substitutes essential for procurement continuity.

Q: What tolerance should I select for my application?

A: The original P10R223K5 specifies ±10% tolerance. Direct substitutes with ±10% tolerance (SA105C223KAA, SA105C223KAC, SA105C223KAN, C410C223K5G5TA) maintain identical circuit performance. Tighter tolerances (±5%, ±2%, ±1%) are available for applications requiring improved capacitance accuracy but are not required for direct replacement.
