Parameter Comparison

Engineering Selection Recommendations

Selection between CD10FD121JO3 and CD10FD121JO3F is determined by compliance requirements and regulatory status applicable to the end application.

CD10FD121JO3 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material status does not present regulatory constraints. This part maintains full Active product status with 979 units currently in inventory.

CD10FD121JO3F is the appropriate selection for applications requiring ROHS3 compliance and REACH-unaffected material status. This variant is also Active and maintains 735 units in current inventory. The CD10FD121JO3F provides equivalent electrical and mechanical performance while meeting enhanced regulatory compliance standards.

Both parts share identical electrical characteristics, physical dimensions, and thermal operating parameters. Selection should be based solely on the compliance and regulatory requirements of the target application and end-use market.

Frequently Asked Questions (FAQ)

Q: Are CD10FD121JO3 and CD10FD121JO3F electrically interchangeable?

A: Yes. Both parts are rated at 120 pF capacitance with ±5% tolerance, 500 V rated voltage, and operate across the identical temperature range of -55°C to 125°C. Electrical performance is equivalent.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts feature identical radial through-hole packages with 0.142" (3.60mm) lead spacing, 0.382" L x 0.201" W body dimensions, and 0.350" (8.90mm) maximum seated height. PCB footprints and mounting requirements are identical.

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

A: The primary difference is regulatory compliance status. CD10FD121JO3F is ROHS3 compliant and REACH unaffected, while CD10FD121JO3 is RoHS non-compliant and REACH affected. Electrical and mechanical specifications are identical.

Q: Which part should be selected for new designs?

A: Selection depends on the regulatory requirements of the target market and application. For applications requiring ROHS3 compliance or REACH compliance, CD10FD121JO3F is the appropriate choice. For applications without these compliance requirements, either part is suitable based on availability and inventory status.

Q: Are there any temperature or voltage derating considerations between these parts?

A: No. Both parts operate identically across the -55°C to 125°C temperature range and maintain the same 500 V rated voltage specification. No derating differences exist between the two parts.

Q: What is the lead spacing specification for these radial capacitors?

A: Lead spacing is 0.142" (3.60mm) for both parts. This specification determines PCB hole pattern and component placement requirements.
