D105F331JO3F Mica Capacitor Equivalent & Substitute Parts

Part Overview

The D105F331JO3F is a 330 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 500 V operation in radial through-hole configuration. This component is classified as Active product status and is suitable for general-purpose applications requiring stable capacitance and high voltage performance. Mica dielectric capacitors are selected for applications demanding low loss, excellent frequency stability, and reliable performance across extended temperature ranges from -55°C to 125°C. Substitute parts are identified when inventory constraints, compliance requirements, or supply chain considerations necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the D105F331JO3F is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

Electrical Parameters (Non-negotiable):

• Capacitance value: 330 pF
• Tolerance: ±5%
• Voltage rating: 500 V (minimum)
• Dielectric material: Mica

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.142" (3.60 mm)
• Physical dimensions: 0.390" L × 0.220" W (9.90 mm × 5.60 mm)
• Maximum seated height: 0.382" (9.70 mm)

Performance Parameters (Required):

• Operating temperature range: -55°C to 125°C (minimum)

Substitute parts identified in this reference maintain complete parametric alignment with the primary component across all specified criteria. Compliance certifications and product status may differ between the main part and substitutes; these differences are documented separately and do not affect electrical or mechanical interchangeability.

Engineering Selection Recommendations

Primary Selection: D105F331JO3F

The D105F331JO3F is the recommended primary selection for new designs and applications requiring full regulatory compliance. This part carries ROHS3 compliance certification and REACH Unaffected status, making it suitable for applications subject to environmental and regulatory restrictions in the European Union and equivalent jurisdictions. Active product status confirms ongoing manufacturer support and availability through established distribution channels.

Substitute Selection: D105F331JO3

The D105F331JO3 is electrically and mechanically identical to the primary part and functions as a direct substitute for applications where RoHS3 compliance is not a requirement. This part is classified as RoHS non-compliant and REACH Affected, indicating it may contain restricted substances or be subject to REACH registration requirements. Selection of this substitute is appropriate for legacy equipment, non-regulated applications, or situations where existing inventory must be utilized. Both parts maintain identical electrical performance, temperature stability, and mechanical compatibility.

Compliance Considerations

Applications subject to RoHS Directive 2011/65/EU or equivalent regulations must specify the D105F331JO3F. Applications without such regulatory constraints may utilize either part based on availability and supply chain considerations. Both parts carry identical ECCN (EAR99) and HTSUS (8532.29.0020) classifications for export control and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can D105F331JO3 be used as a direct replacement for D105F331JO3F in all applications?

A: The D105F331JO3 is electrically and mechanically identical and functions as a direct substitute in applications without RoHS compliance requirements. For applications subject to RoHS Directive 2011/65/EU or equivalent regulations, the D105F331JO3F must be specified. Verify regulatory requirements for your specific application before substitution.

Q: What is the difference between these two part numbers?

A: The primary difference is regulatory compliance status. The D105F331JO3F is ROHS3 Compliant and REACH Unaffected. The D105F331JO3 is RoHS non-compliant and REACH Affected. All electrical parameters, mechanical dimensions, and performance characteristics are identical.

Q: Will the D105F331JO3 fit the same PCB footprint as the D105F331JO3F?

A: Yes. Both parts are radial through-hole capacitors with identical lead spacing of 0.142" (3.60 mm), physical dimensions of 0.390" L × 0.220" W (9.90 mm × 5.60 mm), and maximum seated height of 0.382" (9.70 mm). PCB footprints are interchangeable.

Q: Are there any performance differences between these capacitors?

A: No. Both parts are 330 pF mica capacitors with ±5% tolerance, 500 V rating, and -55°C to 125°C operating temperature range. Electrical performance, frequency stability, and temperature characteristics are identical.

Q: Which part should I specify for new equipment design?

A: Specify D105F331JO3F for new designs. This part carries ROHS3 compliance certification, ensuring compatibility with current and future regulatory requirements in regulated markets. Active product status confirms ongoing manufacturer support.

Q: Can I mix D105F331JO3F and D105F331JO3 in the same production batch?

A: Electrical and mechanical interchangeability is complete. However, mixing parts with different compliance certifications in the same production batch may create documentation and traceability complications. Maintain consistent part selection within production runs when possible.

Q: What does REACH Affected status mean for the D105F331JO3?

A: REACH Affected indicates the part may contain substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. This does not affect electrical performance but may restrict use in certain regulated applications or markets. Verify REACH compliance requirements for your application jurisdiction.

Q: Is the D105F331JO3 still in active production?

A: Yes, both parts are classified as Active product status, indicating ongoing manufacturer production and availability through distribution channels.
