1206ZC155MAT2A Equivalent & Substitute Parts

Part Overview

The 1206ZC155MAT2A is a 1.5 µF ceramic capacitor manufactured by KYOCERA AVX, designed for general-purpose applications in surface-mount configurations. This part operates across a wide temperature range (-55°C to 125°C) with X7R temperature coefficient stability and is rated for 10V operation. The product is currently active and ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the original manufacturer part becomes unavailable, when design requirements demand higher voltage ratings, or when alternative suppliers offer improved lead times and inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1206ZC155MAT2A is determined by the following mandatory parameters:

• Capacitance: Must be 1.5 µF (exact match required)
• Package / Case: Must be 1206 (3216 Metric) for mechanical and electrical compatibility
• Temperature Coefficient: Must be X7R for thermal stability equivalence
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Mounting Type: Must be Surface Mount, MLCC
• Voltage Rating: Must be equal to or greater than 10V (higher ratings provide design margin)

The substitute parts listed below meet all mandatory parameters. Tolerance variations (±10% vs ±20%) and voltage rating increases represent acceptable substitutions for general-purpose applications, as these parameters do not compromise circuit functionality when the circuit design accommodates them.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Recommended for New Designs):

• C1206C155K8RAC7800 (KEMET): Exact voltage match at 10V with active product status. Tighter tolerance (±10%) and lower profile (0.043" thickness) provide improved performance margin. Suitable for direct replacement in production designs.

• C1206C155K4RAC7800 (KEMET): 16V rating provides additional voltage margin over the original 10V specification. Active product status and ±10% tolerance support long-term supply chain stability.

• CL31B155KOFNNNE (Samsung Electro-Mechanics): 16V rating with active product status. Meets all electrical and mechanical requirements. Available in Cut Tape and Digi-Reel packaging options.

Alternative Substitute (Limited Application):

• C3216X7R1E155K160AA (TDK): Meets all electrical specifications with 25V rating. Product status is "Not For New Designs," limiting suitability for new development. Acceptable only for legacy system maintenance or where existing inventory constraints require its use.

All substitute parts maintain ROHS3 compliance, unlimited MSL rating, and identical operating temperature ranges, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the original 10V specification?

A: Yes. Higher voltage ratings (16V or 25V) are acceptable substitutes. Ceramic capacitors with higher voltage ratings maintain the same capacitance and temperature coefficient while providing additional electrical margin. Circuit performance is not compromised by this substitution.

Q: What is the significance of the ±10% tolerance versus ±20% tolerance?

A: The original part specifies ±20% tolerance, while most substitutes offer ±10% tolerance. The tighter ±10% tolerance provides improved capacitance accuracy and is a beneficial substitution for applications requiring tighter component specifications. Circuits designed for ±20% tolerance will function correctly with ±10% components.

Q: Are there physical compatibility concerns with the thickness variations shown in the parameter table?

A: The 1206 (3216 Metric) package footprint is identical across all parts. Thickness variations (0.037" to 0.071") do not affect PCB mounting compatibility. Verify clearance in your specific assembly if height-constrained applications exist, but standard PCB designs accommodate all listed thicknesses without modification.

Q: Why is the TDK part marked "Not For New Designs"?

A: Product status indicates manufacturer lifecycle phase. "Not For New Designs" means the manufacturer is not actively promoting this part for new applications, though existing inventory remains available. For new product development, select parts with "Active" status: C1206C155K8RAC7800, C1206C155K4RAC7800, or CL31B155KOFNNNE.

Q: Do all substitute parts maintain the same RoHS and MSL compliance?

A: Yes. All listed substitutes are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original part's environmental and regulatory certifications.

Q: Which substitute should I select for production designs?

A: For active product status and supply chain continuity, select either C1206C155K8RAC7800 (KEMET) for exact 10V voltage match or C1206C155K4RAC7800 (KEMET) for 16V margin. Both are actively manufactured and support long-term availability.
