Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1210CC103MAT9A are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Identical capacitance value: 10000 pF
• Identical package / case: 1210 (3225 Metric)
• Identical mounting type: Surface Mount, MLCC
• Identical temperature coefficient: X7R
• Identical operating temperature range: -55°C to 125°C
• Identical physical dimensions: 3.30mm L × 2.50mm W × 1.80mm Max Thickness
• Identical RoHS and REACH compliance status

Allowable Variation Parameters:

• Voltage rating: Equal to or greater than 630V
• Tolerance: Equal to or tighter than ±20%
• Manufacturer: Different manufacturers acceptable if all other parameters match

The identified substitute parts (1210AC103KAT1A and KGM32HR73A103KU) maintain all mandatory compatibility parameters while offering improved voltage ratings (1000V vs. 630V) and tighter tolerance specifications (±10% vs. ±20%), making them direct functional upgrades suitable for direct replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with full ROHS3 compliance and REACH unaffected designation, ensuring regulatory compliance across current and future applications. The 1210AC103KAT1A and KGM32HR73A103KU represent functional upgrades to the 1210CC103MAT9A, offering higher voltage ratings (1000V vs. 630V) and improved tolerance specifications (±10% vs. ±20%) while maintaining identical physical form factor and thermal characteristics. Selection between substitute parts should be based on application voltage requirements and tolerance specifications. The KGM32HR73A103KU belongs to the KGM - HV series, indicating optimization for high-voltage applications. All parts are suitable for direct PCB replacement without layout or assembly modifications.

Frequently Asked Questions (FAQ)

Q: Can 1210AC103KAT1A or KGM32HR73A103KU be used as direct replacements for 1210CC103MAT9A?

A: Yes. Both substitute parts maintain identical capacitance, package dimensions, mounting type, temperature coefficient, and operating temperature range. The higher voltage ratings (1000V vs. 630V) and tighter tolerances (±10% vs. ±20%) make them functionally compatible upgrades for direct PCB replacement without circuit redesign.

Q: What is the difference between 1210AC103KAT1A and KGM32HR73A103KU?

A: Both parts share identical electrical specifications (10000 pF, ±10%, 1000V, X7R). The KGM32HR73A103KU is part of the KGM - HV series, specifically designated for high-voltage applications. Selection between these parts should be based on availability, packaging preference (both supplied in Tape & Reel), and application-specific requirements.

Q: Are there any physical compatibility concerns when substituting these parts?

A: No. All three parts use the identical 1210 (3225 Metric) package with matching dimensions (3.30mm L × 2.50mm W × 1.80mm Max Thickness). No PCB layout modifications or assembly process changes are required.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification with identical HTSUS codes (8532.24.0020).

Q: What is the significance of the tighter tolerance in substitute parts?

A: The substitute parts offer ±10% tolerance compared to ±20% for the original part. This provides improved capacitance accuracy, beneficial for applications requiring tighter circuit performance specifications while maintaining backward compatibility.
