CM06FD911JO3 Equivalent & Substitute Parts

Part Overview

The CM06FD911JO3 is a 910 pF mica capacitor rated for 500 V operation in radial through-hole configuration, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as active product status with general-purpose application capability. The mica dielectric material provides stable capacitance across the operating temperature range of -55°C to 125°C with ±5% tolerance.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same functional category. Substitution becomes necessary when the primary part number reaches end-of-life status, inventory constraints occur, or alternative sourcing is required while maintaining identical performance specifications.

Substitute Part Grouping Explanation

Substitution of the CM06FD911JO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (910 pF), tolerance (±5%), and voltage rating (500 V) must be identical. The mica dielectric material ensures consistent performance characteristics across the specified temperature range.

Mechanical Parameters: Radial through-hole mounting configuration, lead spacing of 0.343" (8.70 mm), and physical dimensions of 0.650" L x 0.209" W with maximum seated height of 0.512" must match to ensure direct board-level compatibility without layout modification.

Functional Parameters: General-purpose application classification and operating temperature range of -55°C to 125°C define the functional envelope for substitution.

The CD19FD911JO3F meets all electrical and mechanical equivalence criteria, differing only in series designation (CD19 versus CM06) and compliance certifications, which do not affect electrical or mechanical performance.

Engineering Selection Recommendations

The CD19FD911JO3F provides complete electrical and mechanical equivalence to the CM06FD911JO3 for direct substitution in through-hole circuit board applications. Both components maintain identical capacitance, voltage rating, tolerance, and physical form factor.

The primary distinction between these parts is compliance certification status. The CD19FD911JO3F carries ROHS3 compliance and REACH unaffected status, whereas the CM06FD911JO3 is RoHS non-compliant and REACH affected. Selection between these parts should be based on the regulatory requirements of the end application and target market.

Both components are active products with current manufacturing status and available inventory. The choice between CM06FD911JO3 and CD19FD911JO3F does not affect electrical performance, thermal characteristics, or mechanical compatibility in the circuit design.

Frequently Asked Questions (FAQ)

Q: Can the CD19FD911JO3F replace the CM06FD911JO3 in existing designs?

A: Yes. The CD19FD911JO3F is electrically and mechanically equivalent. Identical capacitance (910 pF), voltage rating (500 V), tolerance (±5%), lead spacing (0.343"), and physical dimensions ensure direct substitution without circuit modification or board layout changes.

Q: What is the difference between the CM06 and CD19 series designations?

A: The series designation indicates the product line within Cornell Dubilier Electronics' mica capacitor portfolio. Both CM06 and CD19 series use identical mica dielectric technology and meet the same electrical specifications for this 910 pF, 500 V rating. The series difference does not affect performance or compatibility.

Q: Are there compliance differences between these parts?

A: Yes. The CD19FD911JO3F is ROHS3 compliant and REACH unaffected, while the CM06FD911JO3 is RoHS non-compliant and REACH affected. Selection should align with the regulatory requirements of the target application and market region.

Q: What are the critical parameters for substitution?

A: Substitution requires matching capacitance (910 pF), voltage rating (500 V), tolerance (±5%), dielectric material (mica), mounting type (through hole), package configuration (radial), and lead spacing (0.343"). All these parameters are identical between the CM06FD911JO3 and CD19FD911JO3F.

Q: Can these parts be used in high-temperature applications?

A: Both components operate across the temperature range of -55°C to 125°C. Mica dielectric material provides stable capacitance performance throughout this range. Application-specific thermal analysis should confirm suitability for the intended operating environment.

Q: Is there any inventory advantage between these parts?

A: Current inventory shows 1046 pieces of CM06FD911JO3 and 1187 pieces of CD19FD911JO3F in stock. Availability may vary based on sourcing requirements and lead time constraints.
