1808AC183KAT3A Equivalent & Substitute Parts

Part Overview

The 1808AC183KAT3A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 0.018 µF with 1000V (1kV) voltage rating and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide temperature range (-55°C to 125°C). The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808AC183KAT3A is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.018 µF
• Capacitance tolerance: ±10%
• Voltage rating: 1000V (1kV) minimum
• Temperature coefficient: X7R
• Package footprint: 1808 (4520 Metric)
• Mounting technology: Surface Mount, MLCC
• Compliance certifications: ROHS3, REACH Unaffected

The substitute part VPDP102W183K1GV001E from Johanson Dielectrics Inc. meets all specified electrical and mechanical parameters, enabling direct substitution in applications where the 1808AC183KAT3A is designated.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808AC183KAT3A and VPDP102W183K1GV001E are active production parts with ROHS3 compliance and REACH Unaffected status. Selection between these parts is based on availability, lead time, and packaging format. The KYOCERA AVX part is available in standard packaging, while the Johanson Dielectrics substitute is supplied in Tape & Reel (TR) format. Both parts satisfy identical electrical performance requirements and mechanical compatibility within the 1808 (4520 Metric) footprint. Inventory levels and procurement timelines should guide final part selection.

Frequently Asked Questions (FAQ)

Q: Can VPDP102W183K1GV001E be used as a direct replacement for 1808AC183KAT3A?

A: Yes. Both parts share identical electrical specifications (0.018 µF, ±10%, 1000V, X7R) and mechanical compatibility (1808 package footprint). Physical dimensions are within acceptable tolerances for surface-mount assembly.

Q: What are the key parameters that determine substitution eligibility?

A: Capacitance value, tolerance, voltage rating, temperature coefficient, package footprint, and mounting technology must match exactly. Both parts meet these criteria.

Q: Are there differences in physical dimensions between these parts?

A: Minor dimensional variations exist within the 1808 package specification. The KYOCERA AVX part measures 4.60mm × 2.00mm × 2.20mm (max thickness), while the Johanson Dielectrics part measures 4.70mm × 2.03mm × 2.16mm (max thickness). These variations remain within standard 1808 package tolerances and do not affect PCB layout compatibility.

Q: What is the difference in packaging format?

A: The 1808AC183KAT3A is supplied in standard packaging, while VPDP102W183K1GV001E is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume automated assembly operations.

Q: Do both parts have the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.
