1812HC102MATME Equivalent & Substitute Parts

Part Overview

The 1812HC102MATME is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 1000 pF with 3000V (3kV) operating voltage and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1812 (4532 Metric) package is designed for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support design flexibility, inventory optimization, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812HC102MATME is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 1000 pF
• Voltage Rating: 3000V (3kV)
• Temperature Coefficient: X7R
• Package / Case: 1812 (4532 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C to 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±20% (main part) to ±10% (upgrade substitutes) — tighter tolerance is acceptable as an upgrade
• Packaging Format: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, or equivalent — packaging format does not affect electrical performance
• Thickness: Minor variations within 0.087" ± 0.01" are acceptable for 1812 package variants
• Manufacturer: KYOCERA AVX or KEMET — both manufacturers produce equivalent X7R high-voltage MLCCs to industry standards

Substitute Categories:

1. Direct Manufacturer Equivalent (KGM43FR73U102MV): Same manufacturer (KYOCERA AVX), identical electrical specifications, different packaging format (Tape & Reel).

2. Upgrade Substitutes (1812HC102KAT1A, KGM43FR73U102KV): Same manufacturer, tighter tolerance (±10% vs. ±20%), identical voltage and capacitance ratings. These provide improved precision for applications requiring tighter capacitance control.

3. Parametric Equivalent (1812HC102MAT1A): Same manufacturer, identical electrical specifications, different packaging format (Cut Tape & Digi-Reel®).

4. Cross-Manufacturer Upgrade (C1812C102KHRAC7800): KEMET equivalent with ±10% tolerance, Low ESL feature, and slightly different physical dimensions (4.50mm × 3.20mm × 1.80mm vs. 4.60mm × 3.20mm × 2.20mm). Acceptable for applications where Low ESL performance is beneficial.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): Select 1812HC102MAT1A or KGM43FR73U102MV when packaging format compatibility permits. Both maintain the original ±20% tolerance specification and are ROHS3 compliant with MSL 1 rating. KGM43FR73U102MV offers higher inventory availability (1476 pcs) in Tape & Reel format for automated assembly.

For Upgraded Precision Applications: Select 1812HC102KAT1A or KGM43FR73U102KV when tighter capacitance tolerance (±10%) is required. Both are KYOCERA AVX products with identical voltage and temperature specifications. KGM43FR73U102KV provides the highest inventory level (3091 pcs) and is available in Tape & Reel format.

For Cross-Manufacturer Substitution: Select C1812C102KHRAC7800 (KEMET) when supply constraints require alternative sourcing. This part offers ±10% tolerance and Low ESL characteristics. Physical dimensions differ slightly (4.50mm length, 1.80mm thickness vs. 4.60mm and 2.20mm); verify PCB layout compatibility before selection. All parts maintain ROHS3 compliance and MSL 1 rating.

Compliance Verification: All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All maintain operating temperature range of -55°C to 125°C and unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1812HC102MATME with KGM43FR73U102MV? A: Yes. Both parts are KYOCERA AVX products with identical electrical specifications (1000 pF, ±20%, 3000V, X7R). The primary difference is packaging format (Tape & Reel vs. Bulk). Verify your assembly process accommodates Tape & Reel format.

Q: What is the difference between ±20% and ±10% tolerance parts? A: Tolerance defines the allowable capacitance variation from the nominal 1000 pF value. ±20% allows 800–1200 pF; ±10% allows 900–1100 pF. Parts with ±10% tolerance (1812HC102KAT1A, KGM43FR73U102KV, C1812C102KHRAC7800) provide tighter capacitance control and are suitable for precision applications. They are direct upgrades to the ±20% specification.

Q: Is the KEMET part C1812C102KHRAC7800 a direct replacement? A: C1812C102KHRAC7800 is a cross-manufacturer equivalent with identical electrical performance (1000 pF, 3000V, X7R, ±10% tolerance). Physical dimensions differ slightly: 4.50mm × 3.20mm × 1.80mm versus 4.60mm × 3.20mm × 2.20mm. Verify PCB footprint and height clearance before substitution.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, and Bulk packaging formats do not affect electrical specifications. Selection depends on assembly equipment compatibility and supply chain requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original 1812HC102MATME specification.

Q: Which substitute part has the highest inventory availability? A: KGM43FR73U102KV (KYOCERA AVX) has the highest inventory at 3091 pcs, available in Tape & Reel format with ±10% tolerance upgrade.
