Engineering Selection Recommendations

Primary Part: CDV16FF241JO3

The CDV16FF241JO3 is the baseline reference part. It is active in production with established inventory (874 units). This part is RoHS non-compliant and REACH Affected, which may impact procurement for regulated applications.

Substitute Part: CDV16FF241JO3F

The CDV16FF241JO3F is a direct electrical and mechanical equivalent with the following distinctions:

RoHS Compliance: ROHS3 Compliant (versus non-compliant baseline)
REACH Status: REACH Unaffected (versus REACH Affected baseline)
Lead Spacing: 0.232" (5.90mm) versus 0.234" (5.94mm) — variance of 0.002" is within standard PCB tolerance for through-hole radial capacitors
Inventory: 761 units available

Selection Criteria:

Use CDV16FF241JO3F when RoHS3 compliance or REACH exemption is required for the end application. Both parts are electrically and mechanically interchangeable for circuit performance. The lead spacing variance does not affect PCB footprint compatibility for standard through-hole radial layouts.

Use CDV16FF241JO3 when compliance certifications are not a procurement requirement and baseline inventory is prioritized.

Frequently Asked Questions (FAQ)

Q: Can CDV16FF241JO3F replace CDV16FF241JO3 on an existing PCB design?

A: Yes. The CDV16FF241JO3F is mechanically and electrically equivalent. The lead spacing difference of 0.002" (0.05mm) is within standard PCB manufacturing tolerance for through-hole radial capacitor footprints and does not require PCB redesign.

Q: What is the difference between these two parts?

A: The parts are identical in electrical performance and mechanical dimensions. The primary differences are RoHS and REACH compliance status. CDV16FF241JO3F is ROHS3 Compliant and REACH Unaffected, while CDV16FF241JO3 is non-compliant and REACH Affected.

Q: Are there any performance differences between CDV16FF241JO3 and CDV16FF241JO3F?

A: No. Both parts have identical capacitance (240 pF), tolerance (±5%), voltage rating (1 kV), operating temperature range (-55°C to 150°C), and RF characteristics (High Q, Low Loss).

Q: Which part should I specify for new designs?

A: Specify CDV16FF241JO3F for new designs requiring RoHS3 compliance or REACH exemption. Both parts are suitable for RF applications with identical electrical performance.

Q: Is the lead spacing difference significant?

A: No. The 0.002" (0.05mm) difference in lead spacing between the two parts is within standard PCB manufacturing tolerance for radial capacitor footprints and does not affect board-level compatibility.

Q: Can I mix these parts in the same production batch?

A: Yes. Both parts are mechanically and electrically interchangeable. However, verify compliance requirements for your specific application before mixing parts with different RoHS and REACH status.

Q: What is the moisture sensitivity level for these capacitors?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
