CD19FD511FO3F Mica Capacitor Equivalent & Substitute Parts

Part Overview

The CD19FD511FO3F is a 510 pF mica capacitor rated for 500 V with ±1% tolerance, manufactured by Cornell Dubilier Electronics (CDE). This through-hole radial component operates across a temperature range of -55°C to 125°C and is classified as Active product status. Mica capacitors in this specification are used in general-purpose applications requiring stable capacitance and low dielectric loss. Substitute parts are identified to address inventory availability, compliance requirements, or series discontinuation scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD19FD511FO3F is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 510 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Material: Mica (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.343" / 8.70 mm (exact match required)
• Physical Dimensions: 0.650" L x 0.201" W / 16.50 mm x 5.10 mm (exact match required)
• Height - Seated (Max): 0.512" / 13.00 mm (exact match required)

The CM06FD511FO3 meets all electrical and mechanical parameters required for direct substitution. Differences in RoHS compliance status, REACH classification, and moisture sensitivity level do not affect functional equivalence but must be evaluated within the context of the end-application regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

CD19FD511FO3F is the primary selection for applications requiring ROHS3 compliance and REACH unaffected status. This part is Active and maintains full regulatory alignment for restricted substance directives.

CM06FD511FO3 is functionally equivalent across all electrical and mechanical parameters and serves as a direct substitute when CD19FD511FO3F inventory is unavailable. However, this part is RoHS non-compliant and REACH Affected. Selection of CM06FD511FO3 is appropriate only in applications where RoHS3 compliance and REACH compliance are not contractual or regulatory requirements. Both parts are Active status and share identical electrical performance characteristics, temperature operating range, and physical form factor.

The choice between these two parts must be driven by the end-application's compliance obligations and supply chain constraints, not by electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can CM06FD511FO3 be used as a direct replacement for CD19FD511FO3F in all applications?

A: CM06FD511FO3 is electrically and mechanically equivalent to CD19FD511FO3F. However, it is RoHS non-compliant and REACH Affected, whereas CD19FD511FO3F is ROHS3 Compliant and REACH Unaffected. Substitution is valid only when regulatory compliance requirements do not mandate RoHS3 or REACH compliance.

Q: Are the physical dimensions identical between CD19FD511FO3F and CM06FD511FO3?

A: Yes. Both parts share identical lead spacing (0.343" / 8.70 mm), overall dimensions (0.650" L x 0.201" W / 16.50 mm x 5.10 mm), and maximum seated height (0.512" / 13.00 mm). PCB layout and mounting procedures are interchangeable.

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

A: CD19 and CM06 are different product series within Cornell Dubilier Electronics' mica capacitor portfolio. Both series contain the 510 pF, 500 V, ±1% specification. Series designation does not affect electrical performance or mechanical compatibility for this capacitance value and voltage rating.

Q: Does the difference in Moisture Sensitivity Level (MSL) affect substitution?

A: CD19FD511FO3F has MSL listed as Not Applicable, while CM06FD511FO3 has MSL 1 (Unlimited). For mica dielectric capacitors, MSL is not a limiting factor in substitution decisions. Both parts are suitable for standard storage and handling conditions.

Q: Are both parts currently in active production?

A: Yes. Both CD19FD511FO3F and CM06FD511FO3 are listed as Active product status, indicating ongoing manufacturing and availability.

Q: What is the tolerance specification, and is it identical between both parts?

A: Both parts carry ±1% tolerance on the 510 pF capacitance value. This tight tolerance is maintained across both the CD19 and CM06 series for this specification.
