Parameter Comparison

Engineering Selection Recommendations

Both CD15FD251FO3 and CD15FD251FO3F are Active product status parts from Cornell Dubilier Electronics' CD15 series with identical electrical and mechanical specifications. The primary differentiation lies in regulatory compliance:

CD15FD251FO3F is the preferred substitute for designs subject to ROHS3 compliance requirements, as it meets ROHS3 standards while the original part is RoHS non-compliant. Additionally, CD15FD251FO3F is REACH Unaffected, offering reduced regulatory complexity in supply chain management. Current inventory levels for CD15FD251FO3F are higher (1093 Pcs) compared to CD15FD251FO3 (631 Pcs).

For applications without RoHS3 or REACH compliance requirements, both parts provide equivalent electrical and mechanical performance and may be selected based on inventory availability or procurement lead time.

Frequently Asked Questions (FAQ)

Q: Are CD15FD251FO3 and CD15FD251FO3F electrically identical? A: Yes. Both parts have identical capacitance (250 pF), tolerance (±1%), voltage rating (500 V), dielectric material (Mica), and operating temperature range (-55°C to +125°C).

Q: Can these parts be used interchangeably in circuit board designs? A: Yes. Both parts have identical mechanical specifications: radial through-hole package, 0.232" lead spacing, 0.469" L x 0.209" W body dimensions, and 0.390" maximum seated height. No PCB layout modifications are required.

Q: What is the difference between these two parts? A: The primary differences are RoHS and REACH compliance status. CD15FD251FO3F is ROHS3 Compliant and REACH Unaffected, while CD15FD251FO3 is RoHS non-compliant and REACH Affected. Both are manufactured by Cornell Dubilier Electronics and belong to the CD15 series.

Q: Which part should I select for a new design? A: Selection depends on regulatory requirements. For designs requiring RoHS3 compliance, use CD15FD251FO3F. Both parts are suitable for general-purpose applications within the specified electrical and thermal parameters.

Q: Are there any performance differences related to temperature or voltage operation? A: No. Both parts have identical operating temperature ranges (-55°C to +125°C) and are rated for 500 V operation. Temperature and voltage performance is equivalent.
