Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD10FA331JO3F is based on the following critical parameters that must remain identical:

• Capacitance Value: 330 pF (exact match required)
• Tolerance: ±5% (defines acceptable range of capacitance deviation)
• Voltage Rating: 100 V (minimum safe operating voltage)
• Dielectric Material: Mica (electrical performance and stability characteristics)
• Mounting Type: Through Hole (assembly compatibility)
• Package / Case: Radial (physical form factor and PCB footprint)
• Lead Spacing: 0.142" (3.60mm) (circuit board hole pattern compatibility)

The CD10FA331JO3 is identified as a parametric equivalent, sharing identical electrical and mechanical specifications while differing in regulatory compliance certifications.

Engineering Selection Recommendations

Primary Specification - CD10FA331JO3F (ROHS3 Compliant)

Select the CD10FA331JO3F for applications requiring compliance with RoHS3 regulations and REACH unaffected status. This variant is the preferred choice for commercial and industrial designs subject to environmental compliance mandates.

Alternative Specification - CD10FA331JO3 (RoHS Non-Compliant)

The CD10FA331JO3 serves as a functional equivalent for legacy systems, military applications, or designs exempt from RoHS3 compliance requirements. While electrically and mechanically identical, this variant is subject to REACH regulations and carries RoHS non-compliant designation.

Both parts are currently in active production with confirmed inventory availability. Selection between variants depends solely on project compliance requirements and regulatory scope.

Frequently Asked Questions (FAQ)

Q: Can CD10FA331JO3 be used as a direct replacement for CD10FA331JO3F?

A: The CD10FA331JO3 is electrically and mechanically equivalent. Direct replacement is possible from a functional standpoint. However, compliance requirements must be evaluated. If RoHS3 compliance is mandatory, the CD10FA331JO3F is the required choice.

Q: What determines if these parts are interchangeable?

A: Interchangeability is determined by matching capacitance (330 pF), tolerance (±5%), voltage rating (100 V), dielectric material (Mica), mounting type (Through Hole), package form (Radial), and lead spacing (0.142" / 3.60mm). All specifications are identical between both variants.

Q: Does the difference in RoHS status affect electrical performance?

A: No. RoHS status is a regulatory classification that indicates manufacturing process compliance, not electrical performance. Both parts deliver identical electrical characteristics and operating specifications.

Q: Are there inventory considerations when selecting between these variants?

A: Yes. CD10FA331JO3F shows 1154 units in stock, while CD10FA331JO3 has 885 units available. Supply availability may influence selection in time-sensitive projects.

Q: What is the significance of lead spacing (0.142" / 3.60mm)?

A: Lead spacing defines the distance between component leads and determines PCB hole pattern compatibility. Both variants share identical spacing, ensuring identical footprint requirements and circuit board mounting compatibility.
