1825SC102MAT3A\SB Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 1825SC102MAT3A\SB is a 1000 pF, 1.5 kV ceramic capacitor manufactured by KYOCERA AVX with X7R temperature coefficient characteristics. This surface mount MLCC (Multilayer Ceramic Capacitor) in 1825 package format is designed for general purpose high voltage applications. The part maintains active product status with 803 units in current inventory. Substitute parts are identified when design requirements allow for higher voltage ratings, improved tolerance specifications, or alternative temperature coefficient options while maintaining the same capacitance value and package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825SC102MAT3A\SB is determined by the following criteria:

Fixed Parameters (Non-Negotiable):

• Capacitance: 1000 pF (exact match required)
• Package / Case: 1825 (4564 Metric) (physical compatibility required)
• Mounting Type: Surface Mount, MLCC (assembly compatibility required)
• Operating Temperature Range: -55°C ~ 125°C (functional requirement)

Allowable Variation Parameters:

• Voltage Rating: May be equal or higher than 1500V
• Tolerance: May be tighter (lower) than ±20%
• Temperature Coefficient: X7R or C0G/NP0 (both acceptable for general purpose applications)
• RoHS and REACH Compliance: Must maintain ROHS3 Compliant and REACH Unaffected status

The three identified substitute parts meet all fixed parameters while offering enhanced specifications in voltage rating (2000V) and tolerance (±5% or ±10%), with temperature coefficient options of either X7R or C0G/NP0.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full ROHS3 compliance with REACH unaffected designation, ensuring regulatory continuity with the original 1825SC102MAT3A\SB specification.

1825GA102JAT1A Selection: This substitute offers the highest voltage rating upgrade (2000V) combined with the tightest tolerance specification (±5%) and C0G/NP0 temperature coefficient. The reduced thickness (0.087" vs 0.100") provides design flexibility for space-constrained applications. Suitable for designs requiring enhanced voltage margin and superior capacitance stability.

1825GA102KAT1A Selection: This substitute provides 2000V voltage rating with ±10% tolerance and C0G/NP0 temperature coefficient. The reduced thickness (0.087") matches 1825GA102JAT1A. Appropriate for applications where voltage upgrade is required with moderate tolerance requirements and stable temperature performance.

1825GC102KAT1A Selection: This substitute maintains the X7R temperature coefficient of the original part while upgrading voltage rating to 2000V and tightening tolerance to ±10%. The thickness specification (0.100") matches the original part exactly. Optimal for designs requiring voltage upgrade while preserving X7R temperature characteristics and maintaining identical physical profile.

Frequently Asked Questions (FAQ)

Q: Can 1825GA102JAT1A be used as a direct replacement for 1825SC102MAT3A\SB?

A: Yes, 1825GA102JAT1A is electrically and mechanically compatible. It provides higher voltage rating (2000V vs 1500V), superior tolerance (±5% vs ±20%), and C0G/NP0 temperature coefficient. The reduced thickness (0.087" vs 0.100") requires verification of available PCB clearance in the assembly.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance change across the -55°C to 125°C operating range. C0G/NP0 provides ±30 ppm/°C, resulting in significantly lower capacitance drift. Both are acceptable for general purpose applications; C0G/NP0 is preferred for precision circuits requiring stable capacitance across temperature variations.

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

A: All substitute parts use 1825 (4564 Metric) package with identical length and width (0.177" L x 0.252" W). Thickness varies: 1825GA102JAT1A and 1825GA102KAT1A are 0.087" maximum, while 1825GC102KAT1A matches the original at 0.100" maximum. Verify PCB layout clearance before selection.

Q: Do substitute parts maintain the same moisture sensitivity level?

A: Yes, all substitute parts maintain MSL 1 (Unlimited) rating, identical to the original 1825SC102MAT3A\SB. No special moisture handling or baking procedures are required.

Q: Which substitute part provides the best voltage safety margin?

A: All three substitute parts provide identical 2000V voltage rating, representing a 33% increase over the original 1500V specification. Selection should be based on tolerance and temperature coefficient requirements rather than voltage margin, as all three exceed the original rating equally.
