CM05FD910FO3 Mica Capacitor Equivalent & Substitute Parts

Part Overview

The CM05FD910FO3 is a 91 pF mica capacitor rated for 500 V with radial through-hole mounting, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as active and currently in production. The CM05 series represents a general-purpose mica capacitor line designed for applications requiring stable capacitance values and high voltage performance across extended temperature ranges.

Identification of equivalent and substitute parts becomes necessary when the primary part number reaches end-of-life status, experiences supply constraints, or when design requirements permit selection from alternative product lines that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CM05FD910FO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 91 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage rating: 500 V (exact match required)
• Dielectric material: Mica (exact match required)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 5.90 mm (exact match required)
• Physical dimensions: 11.70 mm L × 4.60 mm W, 9.10 mm height maximum (exact match required)

Environmental Parameters:

• Operating temperature range: -55°C to 125°C (exact match required)

The CD15FD910FO3F qualifies as a parametric equivalent because it maintains identical values across all electrical, mechanical, and environmental specifications listed above. Both components belong to Cornell Dubilier Electronics' mica capacitor portfolio and share the same functional classification as general-purpose capacitors.

Engineering Selection Recommendations

Primary Selection: CM05FD910FO3

The CM05FD910FO3 remains the primary component choice when supply availability and cost considerations are not constraining factors. This part is active in production and maintains full inventory availability.

Substitute Selection: CD15FD910FO3F

The CD15FD910FO3F serves as a direct parametric equivalent for applications where the CM05FD910FO3 is unavailable. This substitute maintains complete electrical and mechanical compatibility with identical capacitance, voltage rating, tolerance, temperature range, and physical form factor.

Compliance Consideration:

The CD15FD910FO3F offers improved regulatory compliance status. It is ROHS3 compliant and REACH unaffected, whereas the CM05FD910FO3 is RoHS non-compliant and REACH affected. For new designs or applications subject to environmental regulations, the CD15FD910FO3F is the preferred selection. For legacy systems or applications without regulatory constraints, either part is functionally equivalent.

Both components are manufactured by Cornell Dubilier Electronics and carry the same ECCN (EAR99) and HTSUS (8532.29.0020) classifications.
