Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDV16FF331JO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 330 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 1 kV (exact match required)
• Dielectric Material: Mica (exact match required)
• Operating Temperature Range: -55°C to 150°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial (exact match required)
• Series Family: CDV16 (same manufacturer series)

The CDV16FF331JO3F qualifies as a direct substitute based on full alignment with all critical electrical and mechanical parameters. Minor variations in lead spacing (0.234" vs. 0.232") and physical dimensions remain within acceptable tolerances for through-hole radial mounting applications.

Engineering Selection Recommendations

CDV16FF331JO3F as Primary Substitute:

The CDV16FF331JO3F is electrically and mechanically equivalent to the CDV16FF331JO3 across all functional parameters. Selection between these parts should be based on regulatory and compliance requirements:

• For RoHS3-compliant applications: CDV16FF331JO3F is the appropriate selection, as it meets ROHS3 compliance requirements while the original part does not.
• For REACH-regulated environments: CDV16FF331JO3F is unaffected by REACH restrictions, whereas the original part is REACH Affected.
• For applications without compliance constraints: Either part is functionally equivalent; selection may be based on inventory availability or lead time.

Both parts share identical electrical characteristics (330 pF, ±5%, 1 kV), dielectric material (mica), operating temperature range (-55°C to 150°C), and mounting configuration (through-hole radial). The minor lead spacing variation (0.234" vs. 0.232") is within acceptable tolerance for PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can CDV16FF331JO3F be used as a direct replacement for CDV16FF331JO3 in existing designs?

A: Yes. The CDV16FF331JO3F is electrically and mechanically equivalent. All critical parameters—capacitance, tolerance, voltage rating, dielectric material, temperature range, and mounting type—are identical. The lead spacing difference (0.234" vs. 0.232") is a minor variation that does not affect PCB compatibility for standard through-hole radial mounting.

Q: What is the primary difference between these two parts?

A: The primary differences are compliance-related. The CDV16FF331JO3F is ROHS3 compliant and REACH unaffected, while the CDV16FF331JO3 is RoHS non-compliant and REACH affected. Electrically and mechanically, the parts are identical.

Q: Are there any performance differences between CDV16FF331JO3 and CDV16FF331JO3F?

A: No. Both parts exhibit identical RF performance, high Q characteristics, and low loss properties. They are manufactured from the same mica dielectric material and operate across the same temperature range (-55°C to 150°C).

Q: Which part should I specify for new designs?

A: For new designs, CDV16FF331JO3F is recommended due to its ROHS3 compliance and REACH unaffected status, which align with current regulatory standards and reduce future compliance risks.

Q: Is the lead spacing difference significant for PCB layout?

A: No. The lead spacing variation (0.234" vs. 0.232", or 5.94mm vs. 5.90mm) is negligible for standard through-hole radial capacitor footprints and does not require PCB redesign.

Q: Can I mix CDV16FF331JO3 and CDV16FF331JO3F in the same assembly?

A: Yes, from an electrical and mechanical standpoint. However, if the assembly is subject to RoHS or REACH compliance requirements, mixing compliant and non-compliant parts may create documentation and traceability issues. Consistency is recommended for compliance-regulated applications.
