CD15FD131GO3 Equivalent & Substitute Parts

Part Overview

The CD15FD131GO3 is a 130 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 a general-purpose mica capacitor suitable for applications requiring stable capacitance across wide temperature ranges and high voltage tolerance. The part is currently active in production with 773 units in stock. Equivalent substitute parts are identified to provide procurement flexibility, extended availability, or alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require alternative selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD15FD131GO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 130 pF (exact match required)
• Tolerance: ±2% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Material: Mica (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial (exact match required)
• Lead Spacing: 0.232" / 5.90 mm (exact match required)

The substitute part CM05FD131GO3 meets all critical electrical and mechanical parameters. The primary difference between the main part and substitute is the series designation (CD15 versus CM05) and minor variations in moisture sensitivity level classification. Both parts are manufactured by Cornell Dubilier Electronics and share identical functional specifications for capacitance, voltage rating, tolerance, temperature range, and physical dimensions.

Engineering Selection Recommendations

Primary Selection: CD15FD131GO3

The CD15FD131GO3 is the specified part number and should be selected as the primary choice when available. This part is active in production with confirmed inventory of 773 units.

Substitute Selection: CM05FD131GO3

The CM05FD131GO3 is a direct functional equivalent suitable for substitution when CD15FD131GO3 availability is constrained. This part meets all critical electrical and mechanical specifications. The CM05FD131GO3 offers higher inventory availability (1119 units in stock) and represents the same manufacturer's alternative series designation. Both parts share identical compliance status (RoHS non-compliant, REACH Affected, EAR99 classification).

Compliance Considerations

Both parts are RoHS non-compliant and REACH Affected. Selection between these parts should account for application-specific regulatory requirements and end-use market restrictions. No compliance advantage exists between the two options.

Frequently Asked Questions (FAQ)

Q: Can CM05FD131GO3 be used as a direct replacement for CD15FD131GO3 in existing designs?

A: Yes. The CM05FD131GO3 is electrically and mechanically equivalent to the CD15FD131GO3. Both parts have identical capacitance (130 pF), tolerance (±2%), voltage rating (500 V), temperature range (-55°C to 125°C), lead spacing (0.232" / 5.90 mm), and physical dimensions. Direct substitution is supported without circuit modification.

Q: What is the difference between the CD15 and CM05 series designations?

A: The series designation indicates the product line within Cornell Dubilier Electronics' mica capacitor portfolio. Both CD15 and CM05 series are active production lines. The series difference does not affect electrical performance or mechanical compatibility for this specific part number combination.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both CD15FD131GO3 and CM05FD131GO3 have identical dimensions: 0.461" L x 0.181" W (11.70 mm x 4.60 mm) with a maximum seated height of 0.370" (9.40 mm). Lead spacing is 0.232" (5.90 mm) for both parts. PCB layout and mechanical mounting are fully compatible.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection may be based on inventory availability, supplier preference, or procurement lead time. Both parts are active in production and carry identical compliance classifications.

Q: Are there any temperature or voltage derating considerations between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C) and are rated for 500 V. No derating differences exist between the two options.

Q: What is the moisture sensitivity level difference between these parts?

A: The CD15FD131GO3 lists MSL as Not Applicable, while the CM05FD131GO3 is classified as MSL 1 (Unlimited). This difference does not affect substitution eligibility for general-purpose applications. MSL classification is relevant only for surface-mount components or moisture-sensitive storage environments; both parts are through-hole radial components.
