CD19FD302GO3 Equivalent & Substitute Parts

Part Overview

The CD19FD302GO3 is a 3000 pF mica capacitor rated for 500 V operation in a radial through-hole package. Manufactured by Cornell Dubilier Electronics (CDE), this component is classified as Active product status and is suitable for general-purpose applications requiring stable capacitance and high voltage performance. Mica dielectric capacitors are selected for applications demanding low loss, excellent frequency stability, and reliable performance across extended temperature ranges from -55°C to 125°C. Identification of equivalent substitute parts becomes necessary when inventory constraints, lead time requirements, or specific packaging preferences necessitate alternative sourcing while maintaining identical electrical and mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the CD19FD302GO3 and CM06FD302GO3 are Active product status components manufactured by Cornell Dubilier Electronics and carry identical regulatory compliance designations (REACH Affected, ECCN EAR99, HTSUS 8532.29.0020). Selection between these parts is based on availability and inventory status rather than electrical or mechanical performance differentiation.

The CD19FD302GO3 (CD19 series) currently maintains 715 units in stock. The CM06FD302GO3 (CM06 series) maintains 1226 units in stock. Both components are RoHS non-compliant and share identical electrical specifications, thermal performance, and mechanical footprints. Component selection should prioritize availability requirements and supply chain lead time considerations. No performance degradation or functional compromise results from substitution between these parts.

Frequently Asked Questions (FAQ)

Q: Can CM06FD302GO3 be used as a direct replacement for CD19FD302GO3?

A: Yes. The CM06FD302GO3 is a parametric equivalent with identical capacitance (3000 pF), voltage rating (500 V), tolerance (±2%), dielectric material (Mica), operating temperature range (-55°C to 125°C), and mechanical dimensions. Direct substitution requires no circuit modification or PCB redesign.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components share identical dimensions: 0.681" L x 0.280" W (17.30 mm x 7.10 mm), with maximum seated height of 0.551" (14.00 mm), and lead spacing of 0.343" (8.70 mm). PCB footprints are interchangeable.

Q: What is the difference between the CD19 and CM06 series designations?

A: The series designation reflects internal CDE product line classification. Both series employ identical mica dielectric technology and performance characteristics for this specific part number. The series difference does not affect electrical performance or mechanical compatibility.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both components carry identical regulatory status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8532.29.0020. Compliance documentation and certifications are equivalent.

Q: Which part should be selected based on availability?

A: Selection should be based on current inventory status and supply chain requirements. The CM06FD302GO3 currently maintains higher inventory (1226 units) compared to the CD19FD302GO3 (715 units). No technical justification exists for preferring one part over the other.

Q: Is the Moisture Sensitivity Level (MSL) difference significant?

A: The CD19FD302GO3 lists MSL as Not Applicable, while the CM06FD302GO3 lists MSL 1 (Unlimited). For mica dielectric capacitors, this difference reflects classification methodology rather than functional performance variation. Both parts are suitable for standard handling and storage conditions without special moisture control requirements.
