Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 04023C122MAT2A are grouped based on the following substitution criteria:

Primary Matching Parameters:

• Capacitance: 1200 pF (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature: -55°C ~ 125°C (exact match required)

Allowable Variations:

• Voltage Rating: 25V or higher (50V rated parts are acceptable upgrades)
• Tolerance: ±20%, ±10%, or ±5% (tighter tolerances are acceptable)
• Manufacturer: KYOCERA AVX, KEMET, YAGEO, Samsung Electro-Mechanics, Murata Electronics
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®

Substitutes are organized into two categories: direct replacements at 25V rating and upgraded alternatives at 50V rating with improved tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (25V Rating): C0402C122K3RAC7867 (KEMET) is the primary alternative at 25V rating. This part maintains the same voltage specification as the original while offering improved tolerance (±10% versus ±20%), is currently active for new designs, and maintains full ROHS3 compliance and MSL 1 rating.

For Upgraded Applications (50V Rating): When circuit design permits higher voltage rating, the following active parts provide enhanced performance margins:

• 04025C122KAT2A (KYOCERA AVX): Maintains original manufacturer with ±10% tolerance and 50V rating. Highest inventory availability (62593 pcs).
• C0402C122K5RAC7867 (KEMET): KEMET equivalent with ±10% tolerance and 50V rating. Active status with substantial inventory (46090 pcs).
• CC0402JRX7R9BB122 (YAGEO): ±5% tolerance option at 50V rating with high inventory (47246 pcs).

Parts to Avoid for New Designs: GRM155R71H122KA01D and GRM155R71H122KA01J (Murata Electronics) are marked "Not For New Designs" and should be used only for legacy system maintenance or repair applications.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and -55°C ~ 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can I use a 50V rated capacitor in place of the 25V original? A: Yes. A 50V rated capacitor is a valid substitute for a 25V application. The higher voltage rating provides additional safety margin and does not negatively impact circuit performance. All 50V alternatives listed maintain identical capacitance, package, and temperature coefficient specifications.

Q: What is the difference between ±20%, ±10%, and ±5% tolerance? A: Tolerance specifies the allowable deviation from the nominal 1200 pF value. ±20% allows 960–1440 pF, ±10% allows 1080–1320 pF, and ±5% allows 1140–1260 pF. Tighter tolerances (±5% or ±10%) are suitable for applications requiring more precise capacitance values. The original ±20% tolerance is acceptable for general-purpose applications.

Q: Are Tape & Reel and Cut Tape packaging interchangeable? A: Both packaging formats contain identical components and are electrically equivalent. The difference is in the physical reel format used for automated assembly. Tape & Reel (TR) is standard for high-volume production, while Cut Tape (CT) & Digi-Reel® is used for smaller quantities or mixed component orders. Select based on your procurement and assembly requirements.

Q: Why are some parts marked "Not For New Designs"? A: Parts marked "Not For New Designs" are legacy components that manufacturers no longer recommend for new circuit designs. These parts remain available for existing product support and repairs but should not be selected for new development. Use active-status alternatives instead.

Q: Do all substitute parts have the same physical dimensions? A: Yes. All listed substitutes use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L × 0.020" W / 1.00mm × 0.50mm). Maximum thickness varies slightly (0.022" / 0.56mm for the original; 0.022" / 0.55mm for most substitutes), but this difference is negligible for PCB assembly.

Q: Which substitute offers the best availability? A: 04025C122KAT2A (KYOCERA AVX) offers the highest inventory at 62593 pcs, followed by CC0402JRX7R9BB122 (YAGEO) at 47246 pcs and C0402C122K5RAC7867 (KEMET) at 46090 pcs.
