Substitute Part Grouping Explanation

Substitute parts for the 1825AC103MAT3A are qualified based on the following criteria:

• Identical Capacitance: All substitutes maintain 10000 pF capacitance value
• Matching Package: All substitutes use the 1825 (4564 Metric) surface-mount package with identical physical dimensions (0.177" L x 0.252" W, 4.50mm x 6.40mm) and maximum thickness (0.100" / 2.54mm)
• Compatible Temperature Coefficient: All substitutes employ X7R temperature coefficient, ensuring stable performance across -55°C to 125°C operating range
• Voltage Rating Variations: Substitute parts offer rated voltages of 1500V, 2000V, and 3000V, all exceeding or matching the original 1000V specification
• Tolerance Improvement: Substitute parts feature ±10% tolerance compared to the original ±20% tolerance
• Compliance Alignment: All substitutes maintain ROHS3 compliance, MSL 1 rating, and Active product status

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original component. Selection among substitute options depends on circuit voltage requirements:

• 1825SC103KAT1A (1500V rating): Suitable for applications requiring voltage margin above the original 1000V specification while maintaining compact 1825 package footprint
• 1825GC103KAT1A (2000V rating): Appropriate for circuits operating at elevated voltage levels with enhanced safety margin
• 1825HC103KAT1A (3000V rating): Designated for high-voltage applications requiring maximum voltage headroom within the 1825 package constraint

All substitutes provide improved ±10% tolerance compared to the original ±20% tolerance, enhancing circuit performance predictability. Identical physical dimensions and thermal characteristics ensure direct board-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can 1825AC103MAT3A be directly replaced with any of the listed substitutes?

A: Direct replacement is possible when circuit voltage requirements are met. All substitutes share identical capacitance (10000 pF), package dimensions (1825 / 4564 Metric), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). Verify that the substitute's rated voltage meets or exceeds your circuit's maximum operating voltage.

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

A: The main part (1825AC103MAT3A) is rated at 1000V with ±20% tolerance. Substitute parts offer higher voltage ratings (1500V, 2000V, or 3000V) and improved ±10% tolerance, while maintaining all other electrical and mechanical specifications.

Q: Are all parts available in the same packaging format?

A: The main part is supplied in standard packaging, while all substitute parts are available in Tape & Reel (TR) format. Both formats are compatible with automated assembly processes and provide equivalent component functionality.

Q: Do substitute parts require any circuit design modifications?

A: No circuit design modifications are required. All parts maintain identical physical footprints, thermal characteristics, and capacitance values. Higher voltage ratings in substitutes provide additional safety margin without affecting circuit operation.

Q: Which substitute should be selected for maximum voltage headroom?

A: The 1825HC103KAT1A (3000V rating) provides the highest voltage rating within the 1825 package constraint, offering maximum voltage margin for high-voltage applications.
