1808AC103MATME Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1808AC103MATME is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 10000 pF with 1000V (1kV) operating voltage and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1808 (4520 Metric) package is designed for general-purpose applications requiring high-voltage performance. 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 is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance: 10000 pF (exact match required)
• Voltage Rating: 1000V (1kV) minimum (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package / Case: 1808 (4520 Metric) (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)

Secondary Compatibility Parameters:

• Tolerance: ±20% or tighter (±10% acceptable as upgrade)
• Physical Dimensions: Nominal match within standard manufacturing tolerances
• Thickness: Variation acceptable within board assembly constraints
• RoHS Status: ROHS3 Compliant (required)
• Moisture Sensitivity Level: MSL 1 (required)

Substitute parts are grouped into two categories:

Upgrade Parts (Tighter Tolerance): Parts with ±10% tolerance provide improved capacitance stability compared to the ±20% main part specification. These are direct functional upgrades maintaining all other electrical and mechanical parameters.

Parametric Equivalent Parts (Identical Tolerance): Parts with matching ±20% tolerance and identical electrical specifications, differing only in packaging format or manufacturer.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity. Selection between equivalent parts should be based on the following factors:

Same-Manufacturer Substitutes (KYOCERA AVX): Parts 1808AC103KAT1A and 1808AC103MAT1A provide direct substitution with established supply relationships. The 1808AC103KAT1A offers improved tolerance (±10%) while maintaining identical physical dimensions. The 1808AC103MAT1A provides parametric equivalence with matching ±20% tolerance.

Cross-Manufacturer Upgrade (KEMET): The C1808C103KDRAC7800 delivers ±10% tolerance with the lowest thickness profile (0.069"), suitable for space-constrained applications. Low ESL characteristics are documented for this part.

Cross-Manufacturer Upgrade (Johanson Dielectrics): The VPDP102W103K1GV001E from the HVS-PME series provides ±10% tolerance with documented SMPS filtering application suitability.

Thickness Considerations: The KGM42CR73A103KY exhibits maximum thickness of 0.087" (2.21mm), which exceeds the main part specification. This part is suitable only where board assembly height constraints permit the additional thickness.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1808AC103KAT1A for 1808AC103MATME in my design?

A: Yes. The 1808AC103KAT1A is a direct electrical and mechanical substitute with identical capacitance (10000 pF), voltage rating (1000V), temperature coefficient (X7R), and package (1808). The ±10% tolerance is tighter than the ±20% specification of the main part, providing improved capacitance stability. Physical dimensions and thickness are identical.

Q: What is the difference between the KYOCERA AVX parts listed?

A: The 1808AC103MATME and 1808AC103MAT1A are parametric equivalents with identical electrical specifications (10000 pF, ±20%, 1000V, X7R). Both are KYOCERA AVX products with the same physical dimensions and thickness. The 1808AC103KAT1A differs by offering ±10% tolerance instead of ±20%, representing an upgrade in capacitance accuracy.

Q: Are cross-manufacturer parts (KEMET, Johanson Dielectrics) fully compatible?

A: Yes. The KEMET C1808C103KDRAC7800 and Johanson Dielectrics VPDP102W103K1GV001E meet all electrical and mechanical substitution criteria: 10000 pF capacitance, 1000V rating, X7R temperature coefficient, 1808 package, and -55°C to 125°C operating range. Both are ROHS3 compliant with MSL 1 rating. Thickness variations are within acceptable assembly tolerances.

Q: Does thickness variation affect board assembly compatibility?

A: Thickness variations among listed parts range from 0.069" to 0.087". The main part and most substitutes are 0.071" (1.80mm). The KGM42CR73A103KY at 0.087" (2.21mm) is suitable only where board design accommodates the additional height. The C1808C103KDRAC7800 at 0.069" (1.75mm) is compatible with all standard 1808 package assembly processes.

Q: Which substitute offers the best tolerance specification?

A: All upgrade parts (1808AC103KAT1A, KGM42CR73A103KY, C1808C103KDRAC7800, VPDP102W103K1GV001E) provide ±10% tolerance, compared to the ±20% specification of the main part. Selection among these should be based on manufacturer preference, packaging format, and physical dimension requirements.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts, including the main part 1808AC103MATME and all substitutes, are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity) rating.
