1808WC102MATME Equivalent & Substitute Parts

Part Overview

The 1808WC102MATME is a 1000 pF ceramic capacitor rated at 2500V (2.5kV) with X7R temperature coefficient, manufactured by KYOCERA AVX in 1808 (4520 Metric) surface mount package. This high-voltage multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active and ROHS3 compliant. Equivalent and substitute parts are identified when they maintain the same capacitance value, temperature coefficient, package footprint, and mounting characteristics while potentially offering improved voltage ratings or tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1808WC102MATME are qualified based on the following criteria:

Primary Compatibility Requirements:

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

Allowable Variations:

• Voltage Rating: Equal to or greater than 2500V
• Tolerance: ±10% or ±20%
• Physical Dimensions: Within 1808 package specification tolerances
• Manufacturer: Different manufacturers acceptable if all electrical and mechanical parameters align

The substitute parts identified maintain identical capacitance, temperature coefficient, and package specifications. Variations in voltage rating (2500V or 3000V) and tolerance (±10% or ±20%) are acceptable as these represent equal or improved performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. The 1808WC102MATME can be directly replaced with 1808WC102KAT1A when packaging format (Tape & Reel) is compatible with assembly requirements and tolerance specification of ±10% is acceptable.

For applications requiring enhanced voltage margin, 1808HC102KAT1A and KGM42CR73U102KY provide 3000V rating while maintaining identical capacitance and temperature coefficient. Both are KYOCERA AVX products with ±10% tolerance and active status.

VPDP302W102K1GV001E from Johanson Dielectrics Inc. offers 3000V rating with the same electrical specifications. Physical dimensions show minor variation within 1808 package tolerance (0.185" L x 0.080" W versus 0.181" L x 0.079" W), and thickness is 0.085" (2.16mm) compared to 0.087" (2.20mm). This part is suitable for applications where dimensional tolerance permits the variation.

Frequently Asked Questions (FAQ)

Q: Can 1808WC102MATME be replaced with 1808HC102KAT1A?

A: Yes. Both parts share identical capacitance (1000 pF), temperature coefficient (X7R), package (1808), and operating temperature range (-55°C to 125°C). The 1808HC102KAT1A provides higher voltage rating (3000V versus 2500V) and tighter tolerance (±10% versus ±20%), making it a direct upgrade substitute.

Q: What is the difference between 1808WC102KAT1A and 1808WC102MATME?

A: Both parts are KYOCERA AVX 1000 pF, 2500V, X7R ceramic capacitors in 1808 package. The primary difference is tolerance specification: 1808WC102MATME has ±20% tolerance while 1808WC102KAT1A has ±10% tolerance. Packaging format differs (Cut Tape & Digi-Reel versus standard packaging for the main part).

Q: Is VPDP302W102K1GV001E compatible with the 1808WC102MATME footprint?

A: VPDP302W102K1GV001E is mechanically compatible with 1808 package specifications. Physical dimensions show minor variation: 0.185" L x 0.080" W (4.70mm x 2.03mm) compared to 0.181" L x 0.079" W (4.60mm x 2.00mm). Thickness is 0.085" (2.16mm) versus 0.087" (2.20mm). These variations remain within 1808 package tolerance and do not affect PCB layout compatibility.

Q: Why would I choose KGM42CR73U102KY over other 3000V substitutes?

A: KGM42CR73U102KY is a KYOCERA AVX product from the KGM - HV series, maintaining manufacturer consistency with the original part. It provides 3000V rating, ±10% tolerance, and identical electrical characteristics. Selection depends on supply chain preference and packaging format requirements (Tape & Reel).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (1808HC102KAT1A, 1808WC102KAT1A, KGM42CR73U102KY, and VPDP302W102K1GV001E) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original 1808WC102MATME specifications.
