Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825CC103MAT1A are qualified based on the following criteria:

• Identical Capacitance: All substitutes maintain 10000 pF capacitance value
• Identical Package: All substitutes use 1825 (4564 Metric) surface-mount package with matching physical dimensions (4.50mm × 6.40mm × 2.54mm max thickness)
• Identical Temperature Coefficient: All substitutes maintain X7R temperature coefficient and -55°C to 125°C operating range
• Higher Voltage Ratings: Substitute parts provide elevated voltage ratings (1500V, 2000V, 3000V) compared to the main part (630V)
• Improved Tolerance: Substitute parts offer ±10% tolerance compared to the main part's ±20% tolerance
• Compliance Alignment: All substitutes maintain ROHS3 compliance, MSL 1 rating, and identical regulatory classifications

The substitution logic is based on voltage derating capability: higher-rated capacitors can operate safely in lower-voltage applications, making them suitable replacements when circuit requirements or design margins necessitate increased voltage headroom.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are active production components with ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility with the main part. Selection among substitutes should be based on circuit voltage requirements:

• 1825SC103KAT1A (1500V): Suitable for applications requiring moderate voltage margin above 630V specification
• 1825GC103KAT1A (2000V): Appropriate for designs requiring substantial voltage derating capability
• 1825HC103KAT1A (3000V): Optimal for maximum voltage headroom and design safety margin

All substitutes provide improved ±10% tolerance compared to the main part's ±20% tolerance, supporting tighter capacitance specifications where required. Identical package dimensions and thermal characteristics ensure direct board-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the 1825SC103KAT1A, 1825GC103KAT1A, or 1825HC103KAT1A be used as direct replacements for the 1825CC103MAT1A?

A: Yes. All substitute parts maintain identical 10000 pF capacitance, X7R temperature coefficient, 1825 package dimensions, and operating temperature range. Higher voltage ratings do not prevent operation in lower-voltage circuits and provide additional design margin.

Q: What is the primary difference between the main part and substitute parts?

A: The main part (1825CC103MAT1A) is rated at 630V with ±20% tolerance. Substitute parts offer higher voltage ratings (1500V, 2000V, or 3000V) and improved ±10% tolerance, enabling use in higher-voltage applications or designs requiring tighter capacitance control.

Q: Are all parts surface-mount compatible with the same PCB footprint?

A: Yes. All parts use the 1825 (4564 Metric) surface-mount package with identical physical dimensions (4.50mm L × 6.40mm W × 2.54mm max thickness), ensuring compatibility with existing PCB layouts without modification.

Q: Do substitute parts have the same moisture sensitivity and compliance ratings?

A: Yes. All parts maintain MSL 1 (Unlimited) moisture sensitivity level, ROHS3 compliance, and identical regulatory classifications (REACH Unaffected, ECCN EAR99, HTSUS 8532.24.0020).

Q: Which substitute part offers the best availability?

A: The 1825HC103KAT1A (3000V rating) has the highest inventory availability at 25145 pieces, followed by 1825GC103KAT1A (2400 pieces) and 1825SC103KAT1A (1356 pieces).
