Engineering Selection Recommendations

Primary Part: CD19FD511FO3

The CD19FD511FO3 is the specified component for new designs and applications where the CD19 series is established. This part is active in production with 660 pieces available in current inventory.

Substitute Part: CM06FD511FO3

The CM06FD511FO3 serves as a direct parametric equivalent when CD19FD511FO3 availability is constrained. Both parts are manufactured by Cornell Dubilier Electronics and comply with identical electrical, mechanical, and environmental specifications. The CM06 series substitute provides 972 pieces in current inventory, offering enhanced availability.

Compliance Considerations:

Both parts carry identical regulatory classifications:

• RoHS non-compliant status
• REACH Affected designation
• EAR99 export classification
• HTSUS code 8532.29.0020

Selection between these parts should be based on inventory availability, lead time requirements, and established design documentation. No functional or performance differences exist between the two part numbers when applied within specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can CM06FD511FO3 be used as a direct replacement for CD19FD511FO3 in existing designs?

A: Yes. The CM06FD511FO3 is a parametric equivalent with identical electrical ratings (510 pF, ±1%, 500 V), dielectric material (mica), mounting configuration (through-hole radial), lead spacing (0.343"), and physical dimensions. Both parts operate across the same temperature range (-55°C to 125°C) and are manufactured by Cornell Dubilier Electronics.

Q: Are there any differences in the physical footprint between these parts?

A: No. Both parts share identical mechanical specifications: 0.650" length x 0.201" width (16.50 mm x 5.10 mm), lead spacing of 0.343" (8.70 mm), and maximum seated height of 0.512" (13.00 mm). PCB layout and mounting hole spacing remain unchanged.

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

A: The series designation indicates the internal product line classification within Cornell Dubilier Electronics. Both series employ mica dielectric technology and meet identical performance specifications for this 510 pF, 500 V application. The series difference does not affect electrical or mechanical compatibility.

Q: Do both parts have the same moisture sensitivity rating?

A: The CD19FD511FO3 lists MSL as Not Applicable, while the CM06FD511FO3 specifies MSL 1 (Unlimited). Both ratings indicate minimal moisture sensitivity typical of mica capacitors. This difference does not affect substitution suitability for general-purpose applications.

Q: Are the regulatory and compliance classifications identical?

A: Yes. Both parts carry identical designations: RoHS non-compliant, REACH Affected, EAR99 export classification, and HTSUS code 8532.29.0020. No compliance differences exist between the two part numbers.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and lead time requirements. Both parts are active in production. The CD19FD511FO3 offers 660 pieces in stock, while the CM06FD511FO3 provides 972 pieces. For applications where either part is acceptable, the CM06FD511FO3 may offer improved availability.
