1825AC102MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1825AC102MAT1A is a 1000 pF ceramic capacitor rated for 1000V (1kV) with X7R temperature coefficient, manufactured by KYOCERA AVX in 1825 (4564 Metric) surface mount package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent capacitance and package dimensions are maintained while allowing for rated voltage upgrades and tolerance improvements within the same physical footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825AC102MAT1A is determined by the following criteria:

Mandatory Parameters (Must Match):

• Capacitance: 1000 pF
• Package / Case: 1825 (4564 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Voltage - Rated: May be equal to or greater than 1000V
• Tolerance: May be equal to or tighter than ±20%
• Temperature Coefficient: May differ (X7R or C0G/NP0)
• Thickness: May be equal to or less than 0.100" (2.54mm)

Two substitute parts meet these criteria: 1825GA102KAT1A (2kV, C0G/NP0, ±10% tolerance) and 1825GC102KAT1A (2kV, X7R, ±10% tolerance).

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are Active product status with full ROHS3 compliance and REACH Unaffected designation, matching the compliance profile of the main part.

1825GA102KAT1A Selection: This substitute provides doubled voltage rating (2kV) with improved tolerance (±10%) and C0G/NP0 temperature coefficient. The reduced thickness (0.087" vs 0.100") offers design flexibility for space-constrained applications. This part is suitable for applications requiring superior temperature stability and tighter capacitance tolerance.

1825GC102KAT1A Selection: This substitute maintains the X7R temperature coefficient of the main part while providing doubled voltage rating (2kV) and improved tolerance (±10%). Thickness remains at 0.100", ensuring direct mechanical compatibility. This part is suitable for applications requiring consistent X7R performance characteristics with enhanced voltage margin.

Both substitutes are available in Tape & Reel packaging and maintain identical footprint dimensions (0.177" L x 0.252" W), ensuring PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can 1825GA102KAT1A or 1825GC102KAT1A be used as direct replacements for 1825AC102MAT1A?

A: Both parts are direct substitutes. They maintain identical capacitance (1000 pF), package footprint (1825 / 4564 Metric), and operating temperature range (-55°C ~ 125°C). The substitutes provide higher voltage ratings (2kV vs 1kV) and tighter tolerance (±10% vs ±20%), which are compatible with applications designed for the original part.

Q: What is the difference between 1825GA102KAT1A and 1825GC102KAT1A?

A: The primary difference is temperature coefficient: 1825GA102KAT1A uses C0G/NP0 (superior temperature stability), while 1825GC102KAT1A uses X7R (matching the original part). Both provide 2kV rating and ±10% tolerance. 1825GA102KAT1A has reduced thickness (0.087" vs 0.100"), while 1825GC102KAT1A maintains the original thickness.

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

A: Both substitutes fit the 1825 (4564 Metric) package with identical length and width (0.177" L x 0.252" W). 1825GA102KAT1A is thinner (0.087" vs 0.100"), which presents no compatibility issues. Both are surface mount MLCC components with identical mounting requirements.

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

A: Yes. Both 1825GA102KAT1A and 1825GC102KAT1A are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) rating, matching the original part's compliance profile.

Q: What is the significance of the voltage rating upgrade from 1kV to 2kV?

A: The doubled voltage rating provides increased design margin for applications operating near the original 1kV specification. This upgrade does not affect capacitance value or physical dimensions, making it a direct substitution with enhanced electrical performance headroom.

Q: How does tolerance improvement from ±20% to ±10% affect circuit performance?

A: Tighter tolerance (±10%) reduces capacitance variation across the production batch, improving circuit predictability and performance consistency. This is particularly beneficial for precision filtering, timing, and frequency-dependent applications.
