Key Parameters

Substitute Part Grouping Explanation

The 12101C155MAT2A qualifies as a substitute for the 1210DC155MAT2A based on the following alignment of critical parameters:

Matching Parameters:

• Capacitance: 1.5 µF (identical)
• Tolerance: ±20% (identical)
• Temperature Coefficient: X7R (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Package / Case: 1210 (3225 Metric) (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• Physical Dimensions: 0.126" L x 0.098" W, 0.110" max thickness (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Differing Parameter:

• Voltage - Rated: 12101C155MAT2A is rated at 100V versus 1210DC155MAT2A at 35V

The 12101C155MAT2A represents an upgrade path where the higher voltage rating (100V) provides increased design margin while maintaining all other electrical and mechanical specifications. This substitution is valid for applications where the original 35V rating is sufficient, as the higher-rated component can operate safely in lower voltage environments.

Parameter Comparison

Engineering Selection Recommendations

Both the 1210DC155MAT2A and 12101C155MAT2A are active production components from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The 12101C155MAT2A provides identical electrical performance and mechanical compatibility with the added benefit of a higher voltage rating (100V versus 35V). Selection between these parts depends on circuit voltage requirements and application specifications. The substitute part maintains all compliance certifications and environmental ratings of the original component.

Frequently Asked Questions (FAQ)

Q: Can the 12101C155MAT2A replace the 1210DC155MAT2A in all applications?

A: The 12101C155MAT2A is electrically and mechanically compatible with the 1210DC155MAT2A. The higher voltage rating (100V) does not prevent operation in circuits designed for 35V. Compatibility is determined by circuit voltage requirements and application specifications.

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

A: The sole difference is the voltage rating. The 1210DC155MAT2A is rated at 35V, while the 12101C155MAT2A is rated at 100V. All other parameters—capacitance, tolerance, temperature coefficient, package, and dimensions—are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical length (0.126"), width (0.098"), and maximum thickness (0.110"). They are footprint-compatible for PCB assembly.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1210DC155MAT2A and 12101C155MAT2A are ROHS3 compliant and REACH unaffected.
