Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CM06FD821FO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value must equal 820 pF. Tolerance must be ±1% or tighter. Voltage rating must be 500 V or higher. Dielectric material must be mica to ensure equivalent electrical characteristics, stability, and frequency response.

Mechanical Parameters: Mounting type must be through-hole. Package configuration must be radial. Lead spacing must be 0.343" (8.70 mm) to ensure PCB compatibility. Physical dimensions must match or be smaller to fit within allocated board space. Height when seated must not exceed 0.512" (13.00 mm).

Environmental Parameters: Operating temperature range must encompass -55°C to 125°C or be equivalent. Moisture sensitivity level must be compatible with assembly and storage processes.

The substitute part CD19FD821FO3F meets all these criteria and qualifies as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CD19FD821FO3F qualifies as a direct parametric equivalent to the CM06FD821FO3 based on identical electrical, mechanical, and environmental specifications. Both components are manufactured by Cornell Dubilier Electronics and maintain active product status.

A significant distinction exists in regulatory compliance posture. The CD19FD821FO3F achieves ROHS3 compliance and REACH unaffected status, whereas the CM06FD821FO3 is RoHS non-compliant and REACH affected. For applications subject to RoHS or REACH regulatory requirements, the CD19FD821FO3F provides superior compliance alignment.

Both parts carry identical ECCN (EAR99) and HTSUS (8532.29.0020) classifications, indicating equivalent export control and tariff treatment.

Inventory availability shows CD19FD821FO3F at 2831 pieces compared to CM06FD821FO3 at 1152 pieces, providing greater supply security for the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the CD19FD821FO3F be used as a direct replacement for the CM06FD821FO3 in existing designs?

A: Yes. The CD19FD821FO3F is a parametric equivalent with identical capacitance (820 pF), tolerance (±1%), voltage rating (500 V), dielectric material (mica), mounting type (through-hole radial), lead spacing (0.343"), physical dimensions, and operating temperature range (-55°C to 125°C). No circuit redesign or PCB layout modification is required.

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

A: The series designation reflects the internal product line classification within Cornell Dubilier Electronics. Both series employ identical mica dielectric technology and meet the same electrical specifications for this 820 pF 500 V application. The series difference does not affect electrical performance or mechanical compatibility.

Q: Why does the CD19FD821FO3F show ROHS3 compliance while the CM06FD821FO3 does not?

A: This reflects different manufacturing batches or production dates. The CD19FD821FO3F represents a more recent production variant that meets current RoHS3 requirements. For applications requiring RoHS compliance, the CD19FD821FO3F is the appropriate selection.

Q: Are there any lead spacing or footprint differences between these parts?

A: No. Both parts specify identical lead spacing of 0.343" (8.70 mm) and identical physical dimensions of 0.650" L x 0.209" W (16.50 mm x 5.30 mm). PCB footprints are interchangeable.

Q: What is the significance of the MSL (Moisture Sensitivity Level) difference?

A: The CM06FD821FO3 specifies MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or assembly. The CD19FD821FO3F lists MSL as Not Applicable, which is consistent with mica capacitor technology that inherently exhibits minimal moisture absorption. Both parts are suitable for standard assembly processes without special moisture control measures.

Q: Can I mix CM06FD821FO3 and CD19FD821FO3F components in the same production batch?

A: Yes. Both parts are electrically and mechanically identical and can be used interchangeably within the same assembly. However, for traceability and quality documentation purposes, it is standard practice to maintain consistent part sourcing within a single production lot when possible.
