CD19FD561JO3F Mica Capacitor 560 pF 500V Radial - Equivalent & Substitute Parts

Part Overview

The CD19FD561JO3F is a 560 pF mica capacitor rated for 500 V with radial through-hole mounting, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is ROHS3 compliant. Mica capacitors in this specification are used in general-purpose applications requiring stable capacitance, low loss, and high voltage performance across extended temperature ranges (-55°C to 125°C). Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when alternative compliance certifications are required, or when design flexibility across CDE series offerings is needed.

Engineering Selection Recommendations

CD19FD561JO3F Selection Criteria: Select the CD19FD561JO3F when ROHS3 compliance and REACH Unaffected status are mandatory requirements. This part is suitable for applications subject to European Union environmental directives and RoHS regulations. Current inventory of 1056 units supports immediate procurement.

CD19FD561JO3 Selection Criteria: The CD19FD561JO3 is electrically and mechanically identical to the CD19FD561JO3F but does not carry ROHS3 compliance certification. This part is suitable for applications where RoHS compliance is not required. The part remains Active status with 828 units in stock. Use this substitute only when regulatory compliance requirements do not apply.

CM06FD561JO3 Selection Criteria: The CM06FD561JO3 represents an alternative CDE series offering with identical electrical and mechanical specifications. This part is RoHS non-compliant and REACH Affected. The CM06 series designation indicates a different product line within CDE's mica capacitor portfolio. This substitute is suitable for applications where series flexibility is acceptable and compliance certifications are not required. Inventory availability is highest at 1199 units.

All three parts share identical electrical performance, physical dimensions, and thermal operating range. Selection between substitutes depends solely on regulatory compliance requirements and series preference.

Frequently Asked Questions (FAQ)

Q: Can CD19FD561JO3 be used as a direct replacement for CD19FD561JO3F?

A: CD19FD561JO3 is electrically and mechanically identical to CD19FD561JO3F. The primary difference is RoHS compliance status. CD19FD561JO3 is RoHS non-compliant, while CD19FD561JO3F is ROHS3 compliant. Direct substitution is possible only in applications where RoHS compliance is not a requirement.

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

A: Both CD19 and CM06 are CDE mica capacitor series. For the 560 pF 500V radial specification, both series offer identical electrical characteristics, physical dimensions, lead spacing, and operating temperature range. The series designation reflects different product line classifications within CDE's portfolio. Selection between series is based on application requirements and compliance certifications rather than electrical performance.

Q: Are all three parts physically interchangeable on a PCB?

A: Yes. All three parts (CD19FD561JO3F, CD19FD561JO3, and CM06FD561JO3) have identical lead spacing (0.343" / 8.70 mm), package dimensions (0.650" L x 0.201" W), and height (0.512" max). They are physically interchangeable in through-hole radial mounting applications.

Q: Which substitute should I select if RoHS compliance is required?

A: Only CD19FD561JO3F carries ROHS3 compliance certification. If RoHS compliance is mandatory, use CD19FD561JO3F. The other two substitutes (CD19FD561JO3 and CM06FD561JO3) are RoHS non-compliant and are not suitable for applications requiring RoHS certification.

Q: What does "REACH Unaffected" mean for CD19FD561JO3F?

A: REACH Unaffected status indicates that the CD19FD561JO3F is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory requirements. The substitute parts CD19FD561JO3 and CM06FD561JO3 are marked as REACH Affected, meaning they fall under REACH regulatory scope.

Q: Can I mix these three part numbers in the same circuit design?

A: Yes, from an electrical and mechanical standpoint, all three parts are functionally equivalent for the 560 pF 500V specification. However, mixing part numbers in production may complicate supply chain management and compliance documentation. Standardize on a single part number based on your regulatory requirements.

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

A: CD19FD561JO3F and CD19FD561JO3 list MSL as Not Applicable, indicating mica capacitors are inherently moisture-resistant. CM06FD561JO3 lists MSL 1 (Unlimited), which also indicates no moisture sensitivity restrictions. This difference does not affect substitution suitability.
