1206PC472MAT1A Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 1206PC472MAT1A is a 4700 pF ceramic capacitor manufactured by KYOCERA AVX with X7R temperature coefficient and 250V rated voltage. This surface mount multilayer ceramic capacitor (MLCC) in 1206 (3216 metric) package is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active and ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the original part becomes unavailable, when design requirements demand higher voltage ratings, improved tolerance specifications, or when alternative manufacturers offer better inventory availability or cost optimization while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Specifications):

1206PC472KAT1A is the primary direct substitute, offering identical voltage and capacitance with improved ±10% tolerance. Both parts are KYOCERA AVX products with Active status and ROHS3 compliance. This part provides the best compatibility with existing designs.

For Voltage Margin Enhancement:

KGM31DR72H472KU, CC1206KKX7RBBB472, and VJ1206Y472KXEAC provide 500V rating while maintaining ±10% tolerance and X7R characteristics. These are suitable when circuit design permits higher voltage components or when additional safety margin is required. All three are Active status products with ROHS3 compliance.

C3216X7R2J472K115AA (TDK) offers 630V rating with ±10% tolerance and Active status, providing maximum voltage headroom within the X7R family.

For Legacy or Constrained Applications:

KGM31DR72H472MU maintains the original ±20% tolerance with 500V upgrade, suitable for designs where tolerance matching is critical.

C3216X7R2J472M115AA (TDK) provides 630V with ±20% tolerance but carries Not For New Designs status; use only for legacy system maintenance.

GRM31BR72J472KW01L and GRM31BR73A472KW01L (Murata) are Not For New Designs products; reserve for existing production support only.

For Superior Stability Requirements:

C3216C0G2E472J115AA (TDK) uses C0G/NP0 temperature coefficient with ±5% tolerance and 250V rating. This part is recommended when circuit performance demands superior temperature stability and tighter capacitance tolerance, though it differs from the original X7R specification.

Compliance Verification:

All recommended substitutes maintain ROHS3 compliance, MSL 1 rating, and operating temperature range of -55°C to 125°C minimum. All are suitable for surface mount assembly on standard PCB equipment.

Frequently Asked Questions (FAQ)

Q: Can I use a 500V or 630V rated capacitor in place of the 250V 1206PC472MAT1A?

A: Yes. Higher voltage ratings are electrically compatible and provide additional safety margin. The capacitor will function correctly in circuits designed for 250V operation. Verify PCB layout accommodates any thickness variations (typically 0.049" to 0.067" maximum).

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance change across -55°C to 125°C operating range. C0G/NP0 provides superior stability with ±0.3% change per °C, resulting in tighter overall tolerance. C0G/NP0 is preferred for precision timing and filtering circuits; X7R is standard for general purpose applications.

Q: Are KYOCERA AVX, TDK, YAGEO, Murata, and Vishay Vitramon parts interchangeable?

A: Yes, provided all electrical parameters (capacitance, tolerance, voltage, temperature coefficient) and mechanical specifications (package, size, thickness) match. All listed manufacturers produce ROHS3 compliant MLCC components meeting identical industry standards.

Q: Does tolerance improvement from ±20% to ±10% affect circuit performance?

A: Tighter tolerance improves circuit predictability and reduces performance variation across production batches. For general purpose applications, both tolerances are acceptable. For precision filtering, timing, or resonant circuits, ±10% tolerance is preferred.

Q: What does "Not For New Designs" product status mean?

A: Parts marked "Not For New Designs" are in mature or end-of-life phases. They remain available for existing production support and legacy system maintenance but should not be selected for new circuit designs. Use Active status parts for new designs.

Q: Can I substitute VJ1206Y472KXEAC if my circuit operates above 125°C?

A: VJ1206Y472KXEAC has operating temperature range of -55°C to 150°C, extending the upper limit by 25°C. This is acceptable if your circuit requires operation above 125°C. Verify all other circuit components support this extended temperature range.

Q: What is the significance of different thicknesses (0.049" to 0.067")?

A: Thickness variation is within normal 1206 package tolerance. Verify PCB solder paste thickness, reflow profile, and component placement equipment accommodate the specific thickness of your selected part. Consult assembly process specifications if thickness exceeds ±0.010" from your original design.

Q: Are all listed parts available in Tape & Reel packaging?

A: Most substitute parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel packaging suitable for automated assembly. Verify packaging format with your distributor before ordering to ensure compatibility with your pick-and-place equipment.
