Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825AC102MAT3A are qualified based on the following criteria:

Maintained Parameters (Required for Substitution):

• Capacitance: 1000 pF (exact match)
• Package / Case: 1825 (4564 Metric) (exact match)
• Mounting Type: Surface Mount, MLCC (exact match)
• Operating Temperature Range: -55°C ~ 125°C (exact match)
• Physical Dimensions: 0.177" L x 0.252" W (4.50mm x 6.40mm) (exact match)
• RoHS Status: ROHS3 Compliant (maintained)
• Moisture Sensitivity Level: 1 (Unlimited) (maintained)
• Product Status: Active (maintained)

Allowed Variation Parameters:

• Voltage - Rated: May increase from 1000V to 2000V (upgrade)
• Tolerance: May improve from ±20% to ±10% (upgrade)
• Temperature Coefficient: May change from X7R to C0G/NP0 or remain X7R (application-dependent)
• Thickness: May vary within package constraints (2.20mm to 2.54mm)

Two substitute parts meet these criteria with voltage and tolerance upgrades while maintaining all critical electrical and mechanical compatibility parameters.

Parameter Comparison

Engineering Selection Recommendations

1825GC102KAT1A (Preferred Substitute): This part maintains X7R temperature coefficient matching the original 1825AC102MAT3A while providing doubled voltage rating (2000V) and improved tolerance (±10%). Identical thickness specification (0.100" / 2.54mm) ensures direct mechanical compatibility. Highest inventory availability (2556 units) supports production continuity. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are maintained.

1825GA102KAT1A (Alternative Substitute): This part upgrades to C0G/NP0 temperature coefficient with doubled voltage rating (2000V) and improved tolerance (±10%). Reduced thickness (0.087" / 2.20mm) provides additional design margin for space-constrained applications. Adequate inventory (1145 units) supports component sourcing. All compliance certifications are maintained. Selection of this part requires confirmation that C0G/NP0 temperature stability characteristics are acceptable for the application.

Both substitute parts are active products with full compliance documentation and maintain all critical electrical and mechanical parameters required for direct substitution in 1825 (4564 Metric) surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can 1825GA102KAT1A or 1825GC102KAT1A be used as direct replacements for 1825AC102MAT3A?

A: Yes. Both substitute parts maintain identical capacitance (1000 pF), package dimensions (1825 / 4564 Metric), and mounting type (Surface Mount, MLCC). Physical footprint compatibility is confirmed. Electrical performance is enhanced through voltage rating upgrades (1000V to 2000V) and tolerance improvements (±20% to ±10%).

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 identical voltage (2000V) and tolerance (±10%) upgrades. 1825GC102KAT1A has maximum thickness of 0.100" (2.54mm), identical to the original. 1825GA102KAT1A has reduced thickness of 0.087" (2.20mm).

Q: Are there packaging differences between these parts?

A: The main part (1825AC102MAT3A) is supplied in bulk packaging. Both substitute parts are supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. All three parts use identical 1825 (4564 Metric) package / case specifications.

Q: Do all three parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements.

Q: Which substitute part should be selected for new designs?

A: 1825GC102KAT1A is recommended for new designs when X7R temperature coefficient is required. This part maintains temperature coefficient matching while providing voltage and tolerance upgrades. 1825GA102KAT1A is suitable when C0G/NP0 temperature stability is preferred and space constraints benefit from reduced thickness (0.087" vs 0.100").
