1210YC155MAT2A Equivalent & Substitute Parts

Part Overview

The 1210YC155MAT2A is a 1.5 µF ceramic capacitor manufactured by KYOCERA AVX, rated for 16V operation with X7R temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) 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 in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance is required but higher voltage ratings or alternative specifications better suit specific circuit requirements.

Substitute Part Grouping Explanation

The 12101C155MAT2A qualifies as a direct substitute based on the following criteria:

Matching Parameters (Substitution Basis):

• Capacitance: 1.5 µF (identical)
• Tolerance: ±20% (identical)
• Temperature Coefficient: X7R (identical)
• Operating Temperature Range: -55°C to 125°C (identical)
• Package / Case: 1210 (3225 Metric) (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• Manufacturer: KYOCERA AVX (identical)
• RoHS Status: RoHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Differing Parameter (Upgrade Characteristic):

• Voltage - Rated: 100V (versus 16V in main part)

The substitute part maintains all critical electrical and mechanical specifications while providing enhanced voltage rating capability. This represents an upgrade path for applications requiring higher voltage margin or operating in elevated voltage environments.

Parameter Comparison

Engineering Selection Recommendations

Both the 1210YC155MAT2A and 12101C155MAT2A are active production parts with full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current and future applications.

The 1210YC155MAT2A is the appropriate selection for circuits with 16V maximum operating voltage and space-constrained designs where the 1.40mm maximum thickness is required.

The 12101C155MAT2A serves as a substitute when higher voltage margin is needed or when circuits operate at voltages approaching the 16V rating of the main part. The increased thickness (2.79mm maximum) must be accommodated in the PCB layout and assembly process. Both parts maintain identical capacitance, tolerance, temperature coefficient, and thermal operating range, ensuring functional equivalence in the capacitive circuit role.

Frequently Asked Questions (FAQ)

Q: Can 12101C155MAT2A replace 1210YC155MAT2A in any application?

A: The 12101C155MAT2A can replace 1210YC155MAT2A in applications where the increased thickness (2.79mm versus 1.40mm) does not create PCB layout or assembly conflicts. The higher 100V rating provides additional voltage margin but does not affect capacitive performance at lower voltages.

Q: What is the primary difference between these two parts?

A: The primary difference is the voltage rating: 1210YC155MAT2A is rated 16V while 12101C155MAT2A is rated 100V. The substitute also has greater thickness. All other electrical and mechanical specifications remain identical.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts maintain the same operating temperature range of -55°C to 125°C with X7R temperature coefficient, ensuring stable capacitance performance across this range.

Q: Do these parts require special handling during assembly?

A: Both parts have MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or assembly. Standard surface mount assembly processes apply to both parts.

Q: Can the 1210YC155MAT2A be used in place of 12101C155MAT2A?

A: The 1210YC155MAT2A has a lower voltage rating (16V versus 100V) and should not be used as a substitute for 12101C155MAT2A in applications requiring the higher voltage rating. The lower voltage rating limits its use to circuits with maximum operating voltages at or below 16V.
