Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD15FD301GO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 300 pF (exact match required)
• Tolerance: ±2% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Type: Mica (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Configuration: Through Hole Radial (exact match required)
• Lead Spacing: 0.232" / 5.90 mm (exact match required)
• Physical Envelope: 0.469" L × 0.209" W × 0.390" H max (exact match required)

The CM05FD301GO3 meets all substitution criteria as a parametric equivalent. Both parts are manufactured by Cornell Dubilier Electronics and share identical electrical specifications and mechanical form factors. The primary distinction lies in series designation (CD15 versus CM05) and moisture sensitivity level classification.

Parameter Comparison

Engineering Selection Recommendations

CD15FD301GO3 is the primary specification when this exact part number is called out in design documentation or procurement requirements. This part is Active in product status with established inventory availability (629 units).

CM05FD301GO3 serves as a direct parametric equivalent for applications where component substitution is permitted. Both parts are Active products from the same manufacturer with identical electrical performance and mechanical compatibility. The CM05 series designation and MSL classification difference do not affect electrical or mechanical interchangeability in standard through-hole PCB applications. The CM05FD301GO3 maintains higher inventory availability (850 units), supporting supply chain continuity.

Both parts carry identical compliance designations (RoHS non-compliant, REACH Affected, EAR99, HTSUS 8532.29.0020), ensuring regulatory consistency in applications where these certifications are relevant.

Frequently Asked Questions (FAQ)

Q: Can CM05FD301GO3 be used as a direct replacement for CD15FD301GO3?

A: Yes. The CM05FD301GO3 is a parametric equivalent with identical capacitance (300 pF), tolerance (±2%), voltage rating (500 V), dielectric material (Mica), operating temperature range (-55°C to 125°C), mounting type (Through Hole Radial), lead spacing (0.232" / 5.90 mm), and physical dimensions. Both parts are manufactured by Cornell Dubilier Electronics and are electrically and mechanically interchangeable.

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

A: The CD15 and CM05 are different product series from Cornell Dubilier Electronics. For the 300 pF 500 V mica capacitor configuration, the series designation does not affect electrical performance or mechanical form factor. The CM05 series carries an MSL classification of 1 (Unlimited), while the CD15 series lists MSL as Not Applicable.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both CD15FD301GO3 and CM05FD301GO3 share identical physical dimensions: 0.469" L × 0.209" W (11.90 mm × 5.30 mm) with a maximum seated height of 0.390" (9.90 mm). Lead spacing is 0.232" (5.90 mm) for both parts. PCB layout and mounting hole spacing are compatible without modification.

Q: Do both parts have the same compliance certifications?

A: Yes. Both parts carry identical compliance designations: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8532.29.0020. Regulatory and export control requirements are equivalent for both parts.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may be based on inventory availability, supplier preference, or existing design documentation. The CM05FD301GO3 currently maintains higher inventory (850 units versus 629 units for CD15FD301GO3), supporting procurement lead time reduction.
