Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1812PC224MAT3A are qualified based on the following criteria:

Electrical Compatibility:

• Capacitance: 0.22 µF (exact match required)
• Voltage Rating: 250V (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Operating Temperature: -55°C ~ 125°C (exact match required)

Mechanical Compatibility:

• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Size / Dimension: 0.177" L x 0.126" W (4.50mm x 3.20mm) (exact match required)

Allowed Variations:

• Tolerance: ±20%, ±10%, or ±5% (tighter tolerances are acceptable upgrades)
• Thickness: Variations permitted within component height constraints
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) acceptable for equivalent function
• Product Status: Active preferred; Not For New Designs acceptable for equivalent function

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes (Active Status):

1812PC224KAT1A (KYOCERA AVX) — Same manufacturer as primary part with improved ±10% tolerance and reduced thickness. Recommended for direct replacement in new designs.

C1812C224JARAC7800 (KEMET) — Tightest tolerance specification (±5%) with thinner profile (0.065"). Suitable where tolerance margin is critical.

C1812C224KARAC7800 (KEMET) — ±10% tolerance with compact form factor. Active status supports new design implementation.

C4532X7R2E224K230KA (TDK Corporation) — Active status with ±10% tolerance. Thicker profile (0.098") requires PCB layout verification.

GRM43DR72E224KW01L (Murata Electronics) — Active status with ±10% tolerance and moderate thickness (0.087"). Suitable for space-constrained applications.

Legacy Substitutes (Not For New Designs):

C4532X7R2E224M230KA (TDK Corporation) — Equivalent ±20% tolerance to primary part. Use only for legacy system maintenance.

C4532X7R2E224K230KM (TDK Corporation) — Not recommended for new designs despite ±10% tolerance.

QMK432B7224KM-T (Taiyo Yuden) — Not recommended for new designs. Thicker profile (0.106") may conflict with space constraints.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1812PC224MAT3A with any of these parts directly?

A: Yes, all listed parts are electrically and mechanically compatible. However, verify PCB layout clearance for thickness variations. Parts with reduced thickness (KEMET series at 0.065") offer better clearance margins. Parts with increased thickness (QMK432B7224KM-T at 0.106") require confirmation of available board space.

Q: What is the difference between ±20%, ±10%, and ±5% tolerance?

A: Tolerance specifies the acceptable deviation from the nominal 0.22 µF capacitance value. ±20% allows 0.176–0.264 µF; ±10% allows 0.198–0.242 µF; ±5% allows 0.209–0.231 µF. Tighter tolerances (±5%, ±10%) are suitable for applications requiring precise capacitance values and are direct upgrades to the ±20% primary part.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Tape & Reel (TR) and Cut Tape (CT) formats contain identical components and are functionally equivalent.

Q: Why are some parts marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued or is phasing out the product line. These parts remain functionally equivalent but should not be selected for new product development. Use Active status parts for new designs.

Q: What does X7R temperature coefficient mean?

A: X7R specifies the capacitance change over temperature range -55°C to 125°C. X7R tolerance is ±15% across this range, making it suitable for general purpose applications. All listed substitutes maintain X7R specification.

Q: Can I use a substitute with different thickness in my existing PCB design?

A: Thickness variations must be evaluated against PCB layout constraints. Thinner parts (KEMET at 0.065") provide additional clearance. Thicker parts (QMK432B7224KM-T at 0.106") require verification that component height does not interfere with adjacent board features or enclosure constraints.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed parts maintain ROHS3 Compliant status and REACH Unaffected designation, ensuring regulatory compliance for current manufacturing standards.
