KYOCERA AVX 1210AC103MAT9A Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1210AC103MAT9A is a high-voltage ceramic capacitor rated at 10000 pF with 1000V (1kV) operating voltage and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1210 (3225 Metric) package 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 ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and tolerance optimization for specific circuit requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1210AC103MAT9A is determined by strict equivalence in the following parameters: capacitance value (10000 pF), voltage rating (1000V), temperature coefficient (X7R), package form factor (1210 / 3225 Metric), and surface-mount technology. Tolerance variations (±20% to ±10%) are permitted within the same electrical class. All substitute parts maintain identical operating temperature range (-55°C to 125°C), RoHS3 compliance, and MSL 1 rating. Substitute parts are categorized as upgrade options (improved tolerance) or direct equivalents (same tolerance, alternative manufacturer).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and full ROHS3 compliance with unlimited moisture sensitivity rating. Selection between the main part and substitutes is based on tolerance requirements and manufacturer preference.

The upgrade options 1210AC103KAT1A and KGM32HR73A103KU provide ±10% tolerance compared to the ±20% tolerance of the main part, offering improved capacitance stability for applications requiring tighter value control. Both upgrade parts are manufactured by KYOCERA AVX and are electrically and mechanically equivalent to the main part.

The direct equivalent C1210C103MDRAC7800 from KEMET maintains the same ±20% tolerance as the main part and is suitable for applications where manufacturer diversification is required. This part is functionally interchangeable with the 1210AC103MAT9A while maintaining all electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can 1210AC103KAT1A or KGM32HR73A103KU be used as direct replacements for 1210AC103MAT9A?

A: Yes. Both upgrade parts are direct replacements. They share identical capacitance (10000 pF), voltage rating (1000V), temperature coefficient (X7R), package form factor (1210 / 3225 Metric), and operating temperature range (-55°C to 125°C). The upgrade parts offer improved tolerance (±10% versus ±20%), making them suitable for applications requiring tighter capacitance control.

Q: What is the difference between the KYOCERA AVX and KEMET substitute options?

A: The primary difference is manufacturer. The KEMET part C1210C103MDRAC7800 maintains the same electrical specifications and tolerance (±20%) as the main KYOCERA AVX part. All three parts are mechanically compatible in the 1210 package and meet identical compliance requirements (ROHS3, MSL 1).

Q: Are there physical dimension differences between these parts?

A: The main part 1210AC103MAT9A and the KYOCERA AVX upgrade parts (1210AC103KAT1A and KGM32HR73A103KU) have identical dimensions: 0.130" L x 0.098" W (3.30mm x 2.50mm) with maximum thickness of 0.071" (1.80mm). The KEMET part C1210C103MDRAC7800 has slightly different dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) with maximum thickness of 0.061" (1.55mm). Both sets of dimensions are within the 1210 (3225 Metric) package specification and are suitable for standard PCB layouts.

Q: Which substitute part should be selected for improved capacitance accuracy?

A: For applications requiring improved capacitance stability, select either 1210AC103KAT1A or KGM32HR73A103KU. Both parts offer ±10% tolerance compared to the ±20% tolerance of the main part. The KGM32HR73A103KU is part of the KGM - HV series, which is specifically designed for high-voltage applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts (1210AC103KAT1A, KGM32HR73A103KU, and C1210C103MDRAC7800) are ROHS3 compliant with REACH Unaffected status, matching the compliance profile of the main part 1210AC103MAT9A.
