CM05FD111FO3 Equivalent & Substitute Parts

Part Overview

The CM05FD111FO3 is a 110 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 Active product status and is suitable for general-purpose applications requiring high-voltage, precision capacitance in compact form factors. Mica dielectric capacitors are selected for applications demanding stable capacitance across temperature ranges, low loss characteristics, and reliable performance in demanding electrical environments. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across alternative product lines or when compliance requirements necessitate component revision.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CM05FD111FO3 is based on electrical and mechanical parameter equivalence. The following criteria determine valid substitution:

Electrical Parameters (Must Match):

• Capacitance: 110 pF
• Tolerance: ±1%
• Voltage Rating: 500 V
• Dielectric Material: Mica

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: Radial
• Lead Spacing: 0.232" (5.90mm)
• Physical Dimensions: 0.461" L x 0.181" W (11.70mm x 4.60mm)
• Height - Seated (Max): 0.370" (9.40mm)

Environmental Parameters (Must Match):

• Operating Temperature Range: -55°C to 125°C

The CD15FD111FO3F qualifies as a parametric equivalent substitute because all electrical, mechanical, and environmental specifications are identical to the CM05FD111FO3. Both components are manufactured by Cornell Dubilier Electronics and maintain the same functional performance characteristics.

Engineering Selection Recommendations

CM05FD111FO3 Selection Criteria: The CM05FD111FO3 is appropriate for applications where RoHS non-compliance is acceptable and REACH-affected material status does not present regulatory constraints. This component maintains Active product status with established supply availability (898 pcs in stock).

CD15FD111FO3F Selection Criteria: The CD15FD111FO3F is the preferred substitute when RoHS3 compliance is required or when REACH-unaffected material status is mandated by design specifications or regulatory requirements. This component is also Active product status with available inventory (712 pcs in stock). The CD15 series represents an updated product line with enhanced compliance certifications while maintaining identical electrical and mechanical performance.

Compliance Considerations: Selection between these two components should be driven by regulatory requirements applicable to the end application. Both components are manufactured by the same supplier and deliver equivalent functional performance. The primary differentiation is compliance certification status.

Frequently Asked Questions (FAQ)

Q: Can the CD15FD111FO3F be used as a direct replacement for the CM05FD111FO3 in existing designs?

A: Yes. The CD15FD111FO3F is a direct parametric equivalent. All electrical specifications (capacitance, tolerance, voltage rating, dielectric material, temperature range) and mechanical specifications (mounting type, package, lead spacing, physical dimensions, height) are identical. The component will function identically in the circuit and occupy the same physical space on the printed circuit board.

Q: What is the primary difference between these two components?

A: The primary differences are compliance certifications. The CD15FD111FO3F is RoHS3 compliant and REACH unaffected, while the CM05FD111FO3 is RoHS non-compliant and REACH affected. Electrical and mechanical performance are identical.

Q: Are there any lead spacing or footprint differences?

A: No. Both components have identical lead spacing of 0.232" (5.90mm) and identical physical dimensions of 0.461" L x 0.181" W (11.70mm x 4.60mm). The radial package configuration is identical for both parts.

Q: Which component should be selected for new designs?

A: For new designs, the CD15FD111FO3F is the appropriate selection due to its RoHS3 compliance and REACH-unaffected status, which align with current regulatory standards and supply chain requirements.

Q: Are both components still in active production?

A: Yes. Both the CM05FD111FO3 and CD15FD111FO3F maintain Active product status with current inventory availability.

Q: Do these components have different moisture sensitivity levels?

A: The CM05FD111FO3 has Moisture Sensitivity Level (MSL) 1 (Unlimited). The CD15FD111FO3F has MSL listed as Not Applicable. Both classifications indicate minimal moisture sensitivity concerns for handling and storage.
