CD17FD151JO3 Equivalent & Substitute Parts

Part Overview

The CD17FD151JO3 is a 150 pF mica capacitor rated for 500 V operation in radial through-hole configuration, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is designed for RF applications requiring high Q factor and low loss characteristics. The mica dielectric provides excellent stability across the operating temperature range of -55°C to 150°C.

Substitute parts are identified when electrical parameters, mechanical dimensions, and mounting characteristics remain within the allowed specifications for this product category. The primary reason for identifying alternatives is to ensure design continuity when the original part number becomes unavailable or when supply chain optimization is required.

Substitute Part Grouping Explanation

Substitute parts for the CD17FD151JO3 are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match Exactly):

Capacitance: 150 pF
Tolerance: ±5%
Voltage Rating: 500 V
Dielectric Material: Mica

Mechanical Parameters (Must Match Exactly):

Mounting Type: Through Hole
Package Configuration: Radial
Lead Spacing: 0.232" (5.90mm)
Physical Dimensions: 0.461" L x 0.189" W (11.70mm x 4.80mm)
Maximum Seated Height: 0.370" (9.40mm)

Performance Characteristics (Must Match):

Operating Temperature Range: -55°C ~ 150°C
Features: RF, High Q, Low Loss

Parts that satisfy all these parameters are classified as parametric equivalents and direct substitutes. Compliance certifications (RoHS, REACH, ECCN) are secondary considerations and do not affect functional substitutability.
