1206CC103MAT9A Equivalent & Substitute Parts

Part Overview

The 1206CC103MAT9A is a 10000 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 630V with X7R temperature coefficient in 1206 (3216 Metric) surface mount package. This part is currently active and widely used in general purpose applications requiring high voltage performance. Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, temperature coefficient) and mechanical compatibility (package size, mounting type, form factor).

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following parameters:

Capacitance: Must be 10000 pF
Voltage Rating: Must be 630V or higher
Temperature Coefficient: Must be X7R
Package / Case: Must be 1206 (3216 Metric)
Mounting Type: Must be Surface Mount, MLCC
Operating Temperature Range: Must support -55°C ~ 125°C

Parts are grouped into two categories:

Upgrade Parts (±10% tolerance): Offer tighter tolerance than the main part (±20%), providing improved capacitance accuracy while maintaining all other electrical and mechanical specifications.

Direct Equivalents (±20% tolerance): Match the tolerance of the main part but may have different product status or manufacturer specifications.

Engineering Selection Recommendations

For Active Designs: Select from parts with Active product status. The 1206CC103KAT1A (KYOCERA AVX), KGM31ER72J103KU (KYOCERA AVX), CL31B103KHFNFNE (Samsung Electro-Mechanics), and CL31B103KHFNNNE (Samsung Electro-Mechanics) are all suitable replacements. The upgrade parts with ±10% tolerance provide improved capacitance accuracy compared to the original ±20% specification.

For Legacy or Maintenance Applications: Parts marked "Not For New Designs" (C3216X7R2J103M115AA from TDK Corporation, SMK316B7103MF-T and SMK316B7103KF-T from Taiyo Yuden) remain electrically and mechanically compatible but should not be selected for new circuit designs.

Compliance Considerations: All listed parts are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1206CC103MAT9A with a part having ±10% tolerance?

A: Yes. Parts with ±10% tolerance (1206CC103KAT1A, KGM31ER72J103KU, CL31B103KHFNFNE, CL31B103KHFNNNE, SMK316B7103KF-T) are direct upgrades, offering tighter capacitance accuracy while maintaining all electrical and mechanical specifications.

Q: Are there physical size differences between substitute parts?

A: All parts use the 1206 (3216 Metric) package with identical length (0.126" to 0.130") and width (0.063"). Thickness varies between 0.049" (1.25mm) and 0.071" (1.80mm). Verify PCB layout clearance if thickness is critical to your application.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging?

A: Both are surface mount packaging formats suitable for automated assembly. Cut Tape is typically used for smaller quantities or manual placement, while Tape & Reel is standard for high-volume production. Electrical and mechanical performance are identical.

Q: Can I use parts marked "Not For New Designs"?

A: These parts (TDK C3216X7R2J103M115AA and Taiyo Yuden SMK316B7103MF-T and SMK316B7103KF-T) are electrically and mechanically compatible but should only be used for maintenance, repair, or legacy system support. New circuit designs should use Active status parts.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts carry ROHS3 compliance and are REACH unaffected, meeting current environmental and regulatory requirements.
