CD15FD391GO3 Equivalent & Substitute Parts

Part Overview

The CD15FD391GO3 is a 390 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 500 V operation in radial through-hole configuration. 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 primary inventory is unavailable, when supply chain optimization is required, or when alternative series within the same manufacturer's portfolio offer identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the CD15FD391GO3 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CM05FD391GO3 qualifies as a parametric equivalent based on the following criteria:

Electrical Equivalence:

• Identical capacitance value: 390 pF
• Identical tolerance specification: ±2%
• Identical rated voltage: 500 V
• Identical dielectric material: Mica
• Identical operating temperature range: -55°C to 125°C

Mechanical Equivalence:

• Identical mounting type: Through Hole
• Identical package configuration: Radial
• Identical lead spacing: 0.232" (5.90mm)
• Identical physical dimensions: 0.469" L × 0.209" W (11.90mm × 5.30mm)
• Identical seated height: 0.390" (9.90mm)

Functional Equivalence:

• Both components serve general-purpose applications
• Both maintain Active product status
• Both are manufactured by Cornell Dubilier Electronics (CDE)

The primary distinction between CD15FD391GO3 and CM05FD391GO3 is the series designation (CD15 versus CM05), reflecting different product lines within CDE's mica capacitor portfolio. This series difference does not affect electrical performance, mechanical compatibility, or functional application suitability.

Frequently Asked Questions (FAQ)

Q: Can CM05FD391GO3 be used as a direct replacement for CD15FD391GO3?

A: Yes. CM05FD391GO3 is a parametric equivalent with identical electrical specifications (390 pF, ±2%, 500 V), identical dielectric material (Mica), identical operating temperature range (-55°C to 125°C), and identical mechanical configuration (radial through-hole with 0.232" lead spacing). The series designation difference (CM05 versus CD15) reflects different product lines within CDE's portfolio but does not affect functional compatibility.

Q: Are there any physical differences between these parts?

A: No. Both parts have identical physical dimensions (0.469" L × 0.209" W), identical lead spacing (0.232" / 5.90mm), and identical seated height (0.390" / 9.90mm). They are mechanically interchangeable in PCB layouts and through-hole applications.

Q: What is the difference in Moisture Sensitivity Level (MSL)?

A: CD15FD391GO3 lists MSL as Not Applicable, while CM05FD391GO3 specifies MSL 1 (Unlimited). This difference reflects classification methodology between product series but does not indicate different moisture performance characteristics. Both are mica dielectric capacitors with inherent moisture resistance.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both CD15FD391GO3 and CM05FD391GO3 share identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8532.29.0020. Regulatory considerations do not differentiate between these two parts.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and supply chain optimization. Both parts are Active products with identical electrical and mechanical specifications. CM05FD391GO3 and CD15FD391GO3 are functionally equivalent for all application purposes.

Q: Are these parts suitable for high-frequency applications?

A: Both parts are specified as general-purpose mica capacitors. Application suitability depends on specific circuit requirements and frequency ranges, which are not differentiated between these two equivalent parts based on provided specifications.
