1825SC102MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1825SC102MAT1A is a 1000 pF ceramic capacitor rated at 1500V with X7R temperature coefficient, manufactured by KYOCERA AVX in 1825 (4564 Metric) surface mount package. This component is active and in stock, designed for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Substitute parts are identified when equivalent capacitance and package dimensions are maintained while allowing for rated voltage upgrades and tolerance improvements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825SC102MAT1A are qualified based on the following criteria:

Fixed Parameters (Must Match):

• Capacitance: 1000 pF
• Package / Case: 1825 (4564 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature: -55°C ~ 125°C
• Physical dimensions: 0.177" L x 0.252" W (4.50mm x 6.40mm)

Allowable Variations:

• Voltage - Rated: May be equal to or greater than 1500V
• Tolerance: May be equal to or tighter than ±20%
• Temperature Coefficient: X7R or C0G/NP0 (both acceptable for general-purpose applications)
• Thickness: Variation permitted within mechanical constraints

Two substitute parts meet these criteria:

1. 1825GC102KAT1A - Maintains X7R temperature coefficient with upgraded voltage rating (2000V) and improved tolerance (±10%)
2. 1825GA102KAT1A - Upgrades to C0G/NP0 temperature coefficient with higher voltage rating (2000V) and improved tolerance (±10%)

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating, matching the environmental and regulatory requirements of the main part.

1825GC102KAT1A maintains identical temperature coefficient (X7R) and thickness specifications while providing increased voltage margin (2000V vs. 1500V) and tighter tolerance (±10% vs. ±20%). This part is the direct functional upgrade within the same temperature coefficient family.

1825GA102KAT1A provides the highest voltage rating (2000V) and tighter tolerance (±10%) but uses C0G/NP0 temperature coefficient instead of X7R. This part is thinner (0.087" vs. 0.100") and is suitable for applications where superior temperature stability is required. The C0G/NP0 coefficient provides lower capacitance variation across temperature compared to X7R.

Selection between substitutes depends on circuit requirements for temperature stability and available PCB clearance for component thickness.

Frequently Asked Questions (FAQ)

Q: Can 1825GC102KAT1A directly replace 1825SC102MAT1A?

A: Yes. Both parts share identical capacitance (1000 pF), package (1825), temperature coefficient (X7R), and physical dimensions. The substitute has higher voltage rating (2000V vs. 1500V) and tighter tolerance (±10% vs. ±20%), making it functionally compatible and superior in voltage margin.

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

A: Both have identical capacitance, voltage rating, tolerance, and package. The primary difference is temperature coefficient: 1825GC102KAT1A uses X7R (matching the original part), while 1825GA102KAT1A uses C0G/NP0 (superior temperature stability). Additionally, 1825GA102KAT1A is thinner (0.087" vs. 0.100").

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed—1825SC102MAT1A, 1825GC102KAT1A, and 1825GA102KAT1A—are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Can I use a substitute with higher voltage rating in my circuit?

A: Yes. Using a capacitor with higher voltage rating than required does not degrade circuit performance. The 2000V rated substitutes are suitable for any application requiring 1500V or less.

Q: Does package thickness affect PCB layout?

A: Yes. 1825GA102KAT1A has reduced thickness (0.087" vs. 0.100"), which may affect clearance in space-constrained designs. Verify PCB layout compatibility before substitution.

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

A: The main part 1825SC102MAT1A packaging is listed as "-" (not specified). Both substitutes are available in Tape & Reel (TR) format. Confirm packaging requirements for your procurement process.
