1812SA102MAT3A Equivalent & Substitute Parts

Part Overview

The 1812SA102MAT3A is a 1000 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 1500V (1.5kV) with C0G/NP0 temperature coefficient and ±20% tolerance. This surface mount MLCC (multilayer ceramic capacitor) in 1812 (4532 metric) package is designed for general-purpose high-voltage applications. The part is active and in stock with 968 units available. Substitute parts are identified when design requirements allow for higher voltage ratings, alternative temperature coefficients, or improved tolerance specifications while maintaining the same capacitance value and package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1812SA102MAT3A are qualified based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 1000 pF (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Voltage Rating: Equal to or greater than 1500V
• Tolerance: ±5%, ±10%, or ±20%
• Temperature Coefficient: C0G/NP0 or X7R
• Manufacturer: KYOCERA AVX or KEMET

Substitutes are organized by voltage rating tier, with higher voltage ratings providing design margin for applications requiring enhanced reliability or future specification changes.

Parameter Comparison

Engineering Selection Recommendations

Same Voltage Rating (1500V): The 1812SC102MAT1A offers identical voltage performance with X7R temperature coefficient instead of C0G/NP0. Both parts are ROHS3 compliant, active status, and MSL 1. The X7R variant provides thinner profile (0.071" vs 0.087") and higher inventory availability (1080 vs 968 units).

Upgraded Voltage Rating (2000V): Three options are available at 2000V: KGM43FCG3D102JV (C0G/NP0, ±5% tolerance), 1812GC102KAT1A (X7R, ±10% tolerance), and 1812GC102MAT1A (X7R, ±20% tolerance). The KGM43FCG3D102JV maintains C0G/NP0 characteristics with improved ±5% tolerance and 6987 units in stock. KEMET's C1812C102KGRAC7800 provides 2000V X7R with lowest profile (0.061") and highest inventory (60226 units).

Higher Voltage Ratings (2500V and 3000V): The 1812WC102KAT1A (2500V, X7R, ±10%) and 1812HC102KAT1A (3000V, X7R, ±10%) provide enhanced voltage margin. KEMET's C1812C102KHRAC7800 offers 3000V X7R performance with 1390 units available. All higher-voltage substitutes maintain ROHS3 compliance and MSL 1 rating.

All substitute parts are active products with confirmed inventory and meet the mandatory matching parameters for direct substitution in the 1812 package footprint.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1812SA102MAT3A with a higher voltage-rated part? A: Yes. Any substitute with equal or higher voltage rating (1500V or greater) qualifies for direct substitution, provided all other mandatory parameters match: 1000 pF capacitance, 1812 package, surface mount MLCC, -55°C to 125°C operating range, ROHS3 compliance, and MSL 1. Higher voltage ratings provide additional design margin without affecting circuit compatibility.

Q: What is the difference between C0G/NP0 and X7R temperature coefficients? A: Both are provided in the substitute list. C0G/NP0 offers superior temperature stability (0 ppm/°C nominal) and is preferred for precision applications. X7R provides acceptable stability (±15% capacitance change over -55°C to 125°C) at lower cost and often with thinner profiles. Selection depends on application requirements.

Q: Does tolerance affect substitution compatibility? A: Tolerance is an allowable variation parameter. The original part specifies ±20%. Substitutes with ±5% or ±10% tolerance are acceptable and provide tighter capacitance control. Parts with ±20% tolerance are also acceptable. Tighter tolerance does not create incompatibility.

Q: Are KYOCERA AVX and KEMET parts interchangeable? A: Yes, when all mandatory parameters match. Both manufacturers produce 1812 package MLLCs with identical footprints, voltage ratings, capacitance values, and operating temperature ranges. KEMET variants (C1812C102KGRAC7800 and C1812C102KHRAC7800) are qualified substitutes with ROHS3 compliance and MSL 1 rating.

Q: What is the impact of thickness variation on PCB assembly? A: Thickness variations (0.061" to 0.110") do not affect electrical compatibility or footprint placement. Thinner parts (0.061" to 0.071") reduce overall board height and may improve thermal performance. Thicker parts (0.087" to 0.110") are mechanically robust. Selection should consider PCB design constraints and assembly equipment capabilities.

Q: Which substitute offers the best inventory availability? A: KEMET's C1812C102KGRAC7800 (2000V, X7R, ±10%) has the highest inventory at 60226 units. KYOCERA AVX's 1812GC102MAT1A (2000V, X7R, ±20%) offers 14533 units. Both are active products suitable for high-volume applications.
