1210AC101MAT1A Equivalent & Substitute Parts

Part Overview

The 1210AC101MAT1A is a 100 pF ceramic capacitor rated at 1000V (1kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified when they maintain the same capacitance value, voltage rating compatibility, temperature coefficient, and physical package dimensions while potentially offering improved tolerance specifications or higher voltage ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1210AC101MAT1A is determined by the following critical parameters:

• Capacitance Value: Must be 100 pF
• Temperature Coefficient: Must be X7R to ensure stable performance across the operating temperature range
• Package Dimensions: Must be 1210 (3225 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Voltage Rating: Must be equal to or greater than 1000V (1kV)
• Tolerance: May be equal or tighter (lower tolerance value is acceptable)
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

Two substitute parts meet these criteria: the 1210AC101KAT1A from KYOCERA AVX with improved ±10% tolerance at the same 1kV rating, and the C1210C101KGRAC7800 from KEMET with enhanced 2kV voltage rating and ±10% tolerance.

Parameter Comparison

Engineering Selection Recommendations

1210AC101KAT1A (KYOCERA AVX): This substitute offers direct compatibility with identical voltage rating (1kV) and package specifications. The primary advantage is improved tolerance specification (±10% versus ±20%), providing tighter capacitance control. Both parts are ROHS3 compliant with MSL 1 rating and identical operating temperature ranges. This substitute is suitable for applications where improved tolerance is beneficial and voltage requirements remain at 1kV.

C1210C101KGRAC7800 (KEMET): This substitute provides enhanced voltage rating (2kV versus 1kV) while maintaining the same 100 pF capacitance and X7R temperature coefficient. The improved tolerance (±10%) and low ESL characteristics make this suitable for high-voltage applications or designs requiring additional voltage margin. Physical dimensions are within acceptable tolerance for the 1210 package class. ROHS3 compliance and MSL 1 rating are maintained. This substitute is appropriate for applications where higher voltage capability is required or desired.

Frequently Asked Questions (FAQ)

Q: Can 1210AC101KAT1A replace 1210AC101MAT1A directly?

A: Yes. Both parts share identical capacitance (100 pF), voltage rating (1kV), temperature coefficient (X7R), and package dimensions (1210/3225 Metric). The 1210AC101KAT1A provides tighter tolerance (±10% versus ±20%), making it a direct upgrade with no circuit modifications required.

Q: Is C1210C101KGRAC7800 compatible with circuits designed for 1210AC101MAT1A?

A: Yes, with the understanding that the voltage rating is doubled (2kV versus 1kV). The capacitance value, temperature coefficient, and package dimensions are identical. The higher voltage rating provides additional safety margin and is backward compatible with 1kV-rated circuits. Physical dimensions are within acceptable tolerance for the 1210 package class.

Q: What is the significance of the ±10% tolerance improvement in substitute parts?

A: Tighter tolerance (±10% versus ±20%) reduces capacitance variation across the production batch, improving circuit performance consistency and reducing design margin requirements. This is particularly valuable in precision filtering, timing, and tuning applications.

Q: Are there packaging differences between these parts?

A: The main part (1210AC101MAT1A) is supplied in bulk packaging, while both substitutes (1210AC101KAT1A and C1210C101KGRAC7800) are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and does not affect electrical performance.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) rating. All are classified under ECCN EAR99 and HTSUS 8532.24.0020.

Q: Which substitute should be selected for new designs?

A: For new designs, 1210AC101KAT1A is recommended if the 1kV rating is sufficient, as it provides improved tolerance from the same manufacturer. C1210C101KGRAC7800 is recommended if higher voltage capability is desired or if KEMET supply chain preference exists.
