1808CC103MATBE Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1808CC103MATBE is a 10000 pF (10 nF) high-voltage ceramic capacitor manufactured by KYOCERA AVX in the 1808 (4520 Metric) surface-mount package. This X7R temperature coefficient capacitor operates at 630V rated voltage with ±20% capacitance tolerance and is designed for general-purpose high-voltage applications. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when design requirements allow for higher voltage ratings, improved tolerance specifications, or alternative packaging formats while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1808CC103MATBE are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Capacitance value: 10000 pF (exact match required)
• Temperature coefficient: X7R (exact match required)
• Package / Case: 1808 (4520 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Voltage rating: May be equal to or higher than 630V
• Tolerance: May be ±10% or ±20%
• Physical dimensions: Minor variations within 1808 package specification tolerance
• Manufacturer: KYOCERA AVX or equivalent qualified manufacturer
• Packaging format: Cut Tape (CT), Tape & Reel (TR), or Digi-Reel® formats

Four substitute parts meet these criteria, all rated at 1000V (1kV) with improved or equivalent tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory conformance. Selection among qualified substitutes depends on specific design constraints:

1808AC103KAT1A (KYOCERA AVX): Offers 1000V rating with improved ±10% tolerance in Cut Tape or Digi-Reel® packaging. Maintains original 1.80mm thickness for space-constrained applications.

1808AC103MAT1A (KYOCERA AVX): Provides 1000V rating with ±20% tolerance matching the original part's tolerance specification. Available in Tape & Reel format with highest inventory availability (12789 units). Maintains 1.80mm thickness.

KGM42CR73A103KY (KYOCERA AVX, KGM - HV Series): Delivers 1000V rating with ±10% tolerance in the KGM high-voltage series. Thickness increases to 2.21mm; verify PCB layout clearance before selection.

VPDP102W103K1GV001E (Johanson Dielectrics Inc., HVS-PME Series): Rated for 1000V with ±10% tolerance and specified for SMPS filtering applications. Physical dimensions vary slightly (4.70mm × 2.03mm) with 2.16mm thickness; confirm footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a 1000V-rated substitute in place of the 630V-rated 1808CC103MATBE?

A: Yes. Higher voltage ratings are electrically compatible and provide design margin. Verify that PCB layout accommodates any thickness variations (up to 2.21mm for KGM42CR73A103KY versus 1.80mm original).

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

A: Tolerance specifies the allowable capacitance deviation from the nominal 10000 pF value. ±10% tolerance (8500–11500 pF range) provides tighter capacitance control; ±20% tolerance (8000–12000 pF range) allows wider variation. Select based on circuit performance requirements.

Q: Are there physical size differences I need to consider?

A: All parts conform to the 1808 (4520 Metric) package. The original part and KYOCERA AVX substitutes maintain 1.80mm thickness. KGM42CR73A103KY (2.21mm) and VPDP102W103K1GV001E (2.16mm) are thicker; confirm PCB clearance and component placement constraints.

Q: Which substitute offers the best inventory availability?

A: 1808AC103MAT1A has the highest stock level (12789 units). All substitutes are active production parts with confirmed availability.

Q: Can I mix manufacturers in the same design?

A: Yes. KYOCERA AVX and Johanson Dielectrics Inc. substitutes are electrically and mechanically compatible. Verify procurement and supply chain requirements for multi-source designs.

Q: What packaging formats are available?

A: Original part uses standard packaging. Substitutes are available in Cut Tape (CT), Digi-Reel®, and Tape & Reel (TR) formats. Select based on assembly equipment and volume requirements.
