1808HC102MATME High Voltage Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1808HC102MATME is a 1000 pF, 3000V (3kV) ceramic capacitor manufactured by KYOCERA AVX with X7R temperature coefficient and 1808 (4520 Metric) package form factor. This high-voltage surface mount multilayer ceramic capacitor (MLCC) is designed for general purpose applications requiring stable capacitance across a wide 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). Alternative equivalent and substitute parts are necessary when addressing supply chain constraints, inventory availability, or when design specifications permit tolerance upgrades from ±20% to ±10%.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808HC102MATME is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match Exactly):

• Capacitance: 1000 pF
• Voltage Rating: 3000V (3kV)
• Temperature Coefficient: X7R
• Package / Case: 1808 (4520 Metric)
• Operating Temperature Range: -55°C to 125°C
• Mounting Type: Surface Mount, MLCC

Allowable Variation Parameters:

• Tolerance: ±20% (main part) to ±10% (substitute parts) - tighter tolerance is acceptable as an upgrade
• Manufacturer: Different manufacturers permitted if all critical parameters match
• Packaging Format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR) formats are interchangeable for component selection purposes

Compliance Requirements:

• RoHS3 Compliant (all parts meet this requirement)
• Moisture Sensitivity Level: 1 (Unlimited) - all parts meet this requirement

The substitute parts listed below meet all critical electrical and mechanical parameters. Tolerance improvements from ±20% to ±10% represent upgrades that enhance circuit performance without requiring design modification.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active production components with ROHS3 compliance and unlimited moisture sensitivity rating, meeting the regulatory and environmental requirements of the 1808HC102MATME.

1808HC102KAT1A (KYOCERA AVX): Direct manufacturer equivalent with identical physical dimensions and improved tolerance specification (±10% versus ±20%). Same manufacturer ensures consistent quality and reliability characteristics. Available in Cut Tape and Digi-Reel® packaging formats.

KGM42CR73U102KY (KYOCERA AVX, KGM - HV Series): Same manufacturer high-voltage series component with ±10% tolerance upgrade. Thickness specification of 2.21mm represents negligible variation from the main part. Available in Tape & Reel format.

VPDP302W102K1GV001E (Johanson Dielectrics Inc., HVS-PME Series): Cross-manufacturer substitute with ±10% tolerance upgrade. Dimensional variations are within acceptable mechanical tolerances: length 4.70mm (versus 4.60mm), width 2.03mm (versus 2.00mm), and thickness 2.16mm (versus 2.20mm). Specified for SMPS filtering applications. Available in Tape & Reel format.

CHV1808N3K0102MXT (Cal-Chip Electronics, Inc., CHV Series): Parametric equivalent maintaining the original ±20% tolerance specification. Identical physical dimensions and electrical characteristics to the main part. Available in Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1808HC102KAT1A for 1808HC102MATME in my design?

A: Yes. The 1808HC102KAT1A is a direct equivalent from the same manufacturer with identical electrical and mechanical specifications. The tolerance improvement from ±20% to ±10% represents an upgrade that enhances circuit performance without requiring design modification.

Q: What is the difference between the tolerance ratings of ±20% and ±10%?

A: Tolerance defines the allowable deviation of actual capacitance from the nominal 1000 pF value. A ±20% tolerance permits capacitance between 800 pF and 1200 pF. A ±10% tolerance permits capacitance between 900 pF and 1100 pF. Tighter tolerance (±10%) provides more precise capacitance values and is suitable as a direct substitute for ±20% applications.

Q: Are there dimensional differences between substitute parts?

A: Most substitute parts maintain identical dimensions of 4.60mm length x 2.00mm width x 2.20mm thickness. The VPDP302W102K1GV001E has minor dimensional variations (4.70mm x 2.03mm x 2.16mm) that remain within acceptable mechanical tolerances for 1808 package form factor applications and standard PCB footprints.

Q: Can I use VPDP302W102K1GV001E if my PCB layout is tight?

A: The dimensional variations of the VPDP302W102K1GV001E are minimal and within standard 1808 package tolerances. However, verify your specific PCB footprint design to confirm accommodation of the slightly larger length (4.70mm versus 4.60mm) and width (2.03mm versus 2.00mm) dimensions.

Q: What packaging formats are available for these substitute parts?

A: 1808HC102KAT1A is available in Cut Tape (CT) and Digi-Reel® formats. KGM42CR73U102KY, VPDP302W102K1GV001E, and CHV1808N3K0102MXT are available in Tape & Reel (TR) format. Select packaging based on your procurement and assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts meet ROHS3 compliance requirements and carry unlimited moisture sensitivity rating (MSL 1), matching the environmental and regulatory specifications of the 1808HC102MATME.

Q: Which substitute part should I select for new designs?

A: For new designs, 1808HC102KAT1A or KGM42CR73U102KY are recommended as they provide ±10% tolerance improvement from the same manufacturer (KYOCERA AVX), ensuring consistent quality and reliability. VPDP302W102K1GV001E is suitable if cross-manufacturer sourcing is required. CHV1808N3K0102MXT maintains the original ±20% tolerance specification and is suitable for direct replacement scenarios.
