Parameter Comparison

Engineering Selection Recommendations

Both the CD30FD123FO3 and CD30FD123FO3F are electrically and mechanically equivalent components suitable for the same circuit applications. The primary distinction between the two parts is their compliance status:

• CD30FD123FO3F is ROHS3 compliant and REACH unaffected, making it the preferred selection for applications subject to environmental and regulatory compliance requirements in the European Union and other jurisdictions with RoHS and REACH mandates.

• CD30FD123FO3 remains RoHS non-compliant and REACH affected. This part may be appropriate for legacy systems, non-regulated applications, or where existing stock must be utilized within the design lifecycle.

Both parts are Active status components with adequate inventory availability. The CD30FD123FO3F offers superior compliance posture and higher current inventory levels (1088 Pcs vs. 679 Pcs), supporting extended supply chain planning.

Frequently Asked Questions (FAQ)

Q: Are CD30FD123FO3 and CD30FD123FO3F electrically identical?

A: Yes. Both parts have identical electrical specifications: 0.012 µF capacitance, ±1% tolerance, 500 V rated voltage, and mica dielectric material with operating temperature range of -55°C to 125°C.

Q: Can these parts be used interchangeably on a PCB?

A: Yes. The parts share identical mechanical parameters including radial through-hole mounting, lead spacing of 0.437" (11.10 mm), and physical dimensions of 0.799" L x 0.358" W. No PCB design modifications are required when substituting between these parts.

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

A: The CD30FD123FO3F is ROHS3 compliant and REACH unaffected, while the CD30FD123FO3 is not. For applications requiring regulatory compliance, the CD30FD123FO3F is the appropriate selection.

Q: Are there any temperature or voltage derating considerations when using the substitute part?

A: No. Both parts operate identically across the full -55°C to 125°C temperature range at 500 V rated voltage. No derating or operational adjustments are required.

Q: Can the CD30FD123FO3 be used in designs certified for ROHS or REACH compliance?

A: No. The CD30FD123FO3 is not ROHS3 compliant and is REACH affected. Designs requiring compliance certifications must use the CD30FD123FO3F substitute part.
