CDV16FF181JO3 Equivalent & Substitute Parts

Part Overview

The CDV16FF181JO3 is a 180 pF mica capacitor rated for 1 kV operation in radial through-hole configuration, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and features RF-grade characteristics with high Q and low loss properties suitable for high-frequency applications.

Identification of substitute parts becomes necessary when the primary part number reaches inventory constraints, when compliance requirements change, or when design revisions require updated component certifications. The substitute part maintains electrical and mechanical equivalence while potentially offering improved regulatory compliance or availability.

Substitute Part Grouping Explanation

Substitution of the CDV16FF181JO3 is based on strict equivalence across the following critical parameters:

Capacitance Value: 180 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage Rating: 1 kV (exact match required)
Dielectric Type: Mica (exact match required)
Mounting Configuration: Through Hole Radial (exact match required)
Lead Spacing: 0.234" / 5.94 mm (exact match required)
Temperature Range: -55°C to 150°C (exact match required)
Series Classification: CDV16 (exact match required)

The substitute part CDV16FF181JO3F maintains complete electrical and mechanical equivalence across all specified parameters. Substitution is valid when component selection criteria are limited to these parameters and when regulatory compliance status is a consideration factor.
