CD15FD301GO3F Equivalent & Substitute Parts

Part Overview

The CD15FD301GO3F is a 300 pF mica capacitor rated for 500 V operation, manufactured by Cornell Dubilier Electronics (CDE). This through-hole radial component is designed for general-purpose applications requiring stable capacitance and high voltage performance. The part is currently active in production with 968 units in stock.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or when design requirements permit alternative series within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CD15FD301GO3F is determined by matching the following critical parameters:

Capacitance Value: 300 pF (exact match required)
Tolerance: ±2% (exact match required)
Voltage Rating: 500 V (exact match required)
Dielectric Material: Mica (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)
Physical Dimensions: 0.469" L × 0.209" W (11.90 mm × 5.30 mm) (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)

The CM05FD301GO3 meets all critical electrical and mechanical parameters and is classified as a parametric equivalent. Differences in compliance certifications and product series do not affect functional interchangeability in applications where the specified electrical and mechanical requirements are the primary selection criteria.

Engineering Selection Recommendations

Primary Selection: CD15FD301GO3F is the recommended choice for new designs and applications requiring ROHS3 compliance and REACH unaffected status. This part is actively produced and maintains higher inventory levels.

Substitute Selection: CM05FD301GO3 is electrically and mechanically equivalent and may be selected when CD15FD301GO3F availability is constrained. Selection of the CM05FD301GO3 requires confirmation that the application does not mandate ROHS3 compliance or REACH unaffected status. Both parts are active products from the same manufacturer and share identical electrical performance and physical form factors.

Compliance Considerations: Applications subject to RoHS3 or REACH regulatory requirements must use CD15FD301GO3F. Applications without these compliance mandates may use either part interchangeably based on availability and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Are CD15FD301GO3F and CM05FD301GO3 electrically interchangeable?

A: Yes. Both parts have identical capacitance (300 pF), tolerance (±2%), voltage rating (500 V), dielectric material (mica), and operating temperature range (-55°C to 125°C). They are parametric equivalents.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical lead spacing (0.232" / 5.90 mm), body dimensions (0.469" L × 0.209" W / 11.90 mm × 5.30 mm), and seated height (0.390" / 9.90 mm). They are mechanically interchangeable in through-hole PCB applications.

Q: What is the difference between these two parts?

A: The primary differences are product series designation (CD15 versus CM05), RoHS compliance status (ROHS3 compliant versus non-compliant), REACH status (unaffected versus affected), and moisture sensitivity level classification. Electrical and mechanical specifications are identical.

Q: Which part should I specify for a new design?

A: Specify CD15FD301GO3F for new designs unless regulatory or supply chain constraints require otherwise. This part maintains active production status, higher inventory availability, and ROHS3 compliance.

Q: Can I use CM05FD301GO3 as a replacement in existing assemblies?

A: Yes, provided the application does not have explicit RoHS3 or REACH compliance requirements. The parts are electrically and mechanically equivalent and will function identically in the circuit.

Q: Are both parts available from the same manufacturer?

A: Yes. Both CD15FD301GO3F and CM05FD301GO3 are manufactured by Cornell Dubilier Electronics (CDE) and are active products.

Q: What is the lead spacing tolerance?

A: Both parts have a lead spacing of 0.232" (5.90 mm), which accommodates standard 0.1" grid PCB layouts with appropriate hole positioning.
