1808CC103MAT1A Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 1808CC103MAT1A is a 10000 pF (0.01 µF) high-voltage ceramic capacitor manufactured by KYOCERA AVX with X7R temperature coefficient and 630V rated voltage. This surface-mount multilayer ceramic capacitor (MLCC) in 1808 (4520 Metric) package is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant with MSL 1 rating and is currently in active production status. Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, or meet specific performance requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1808CC103MAT1A are qualified based on the following criteria:

Electrical Parameters (Must Match or Exceed):

• Capacitance: 10000 pF (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Operating Temperature Range: -55°C to 125°C (minimum requirement)
• Voltage Rating: Equal to or greater than 630V
• Tolerance: ±20% or tighter (±10% acceptable as upgrade)

Mechanical Parameters (Must Match or Be Compatible):

• Package / Case: 1808 (4520 Metric) footprint
• Mounting Type: Surface Mount, MLCC
• Physical dimensions: Compatible with 1808 package specifications
• MSL Rating: 1 (Unlimited) or equivalent

Compliance & Status:

• RoHS3 Compliant (required)
• Active production status (preferred)
• REACH Unaffected status (maintained)

All substitute parts listed meet or exceed these criteria. Substitutes with higher voltage ratings (1000V) provide additional design margin. Tolerance variations (±10% vs. ±20%) represent performance upgrades where tighter tolerance is beneficial.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating): The 1808CC103MAT1A operates at 630V rated voltage. No direct equivalent with identical 630V rating is listed among the substitutes. The original part remains the specified choice for 630V applications.

Upgraded Substitutes (Higher Voltage Rating): All four substitute parts operate at 1000V (1kV) rated voltage, providing 370V additional voltage margin above the original 630V specification. These parts are suitable for applications where higher voltage capability is acceptable or beneficial:

• 1808AC103MAT1A: Same manufacturer (KYOCERA AVX), same tolerance (±20%), same thickness (1.80mm). Highest inventory availability (12789 Pcs). Recommended for direct substitution where voltage upgrade is acceptable.

• 1808AC103KAT1A: Same manufacturer (KYOCERA AVX), tighter tolerance (±10%), same thickness (1.80mm). Suitable where improved capacitance tolerance is required.

• KGM42CR73A103KY: Same manufacturer (KYOCERA AVX), tighter tolerance (±10%), increased thickness (2.21mm). Part of KGM HV series. Verify PCB clearance for increased height before selection.

• VPDP102W103K1GV001E: Alternative manufacturer (Johanson Dielectrics Inc.), tighter tolerance (±10%), increased thickness (2.16mm). HVS-PME series optimized for SMPS filtering applications. Verify PCB clearance for increased height before selection.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and active production status.

Frequently Asked Questions (FAQ)

Q: Can I use a 1000V-rated capacitor in place of a 630V-rated capacitor?

A: Yes. A higher voltage rating provides additional safety margin and is electrically compatible. The 1000V substitutes will function correctly in circuits designed for 630V operation. Verify that PCB layout and thermal management remain adequate.

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

A: Tolerance specifies the allowable deviation from the nominal 10000 pF capacitance value. ±20% allows 8000 pF to 12000 pF; ±10% allows 9000 pF to 11000 pF. Tighter tolerance (±10%) is beneficial for precision filtering, timing circuits, or applications with strict capacitance requirements.

Q: Are the thickness differences between substitute parts significant?

A: The original 1808CC103MAT1A has 1.80mm maximum thickness. Substitutes KGM42CR73A103KY (2.21mm) and VPDP102W103K1GV001E (2.16mm) are thicker. Verify PCB clearance, component spacing, and solder reflow profiles before selecting thicker alternatives. The 1808AC103MAT1A and 1808AC103KAT1A maintain the original 1.80mm thickness.

Q: Can I mix different manufacturers in the same design?

A: Yes. All listed parts meet the same electrical specifications, package requirements, and compliance standards. However, verify that your procurement and quality assurance processes accommodate multiple manufacturers if required by your organization's standards.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 indicates Moisture Sensitivity Level 1, the lowest moisture sensitivity rating. These parts have unlimited shelf life and do not require special moisture-control storage or handling procedures.

Q: Which substitute offers the best inventory availability?

A: The 1808AC103MAT1A offers the highest inventory (12789 Pcs), followed by VPDP102W103K1GV001E (5347 Pcs) and KGM42CR73A103KY (4938 Pcs).
