Frequently Asked Questions (FAQ)

Q: Are CD10ED430JO3 and CD10ED430JO3F electrically identical?

A: Yes. Both parts feature 43 pF capacitance at ±5% tolerance, 500 V rated voltage, mica dielectric material, and identical operating temperature range (-55°C to 125°C). Electrical performance is equivalent.

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

A: Yes. Both parts share identical physical dimensions (0.370" L x 0.189" W), lead spacing (0.142" / 3.60 mm), and radial through-hole mounting configuration. PCB layout and assembly processes require no modification.

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

A: The primary difference is regulatory compliance status. CD10ED430JO3F is ROHS3 compliant and REACH unaffected, while CD10ED430JO3 is RoHS non-compliant and REACH affected. All electrical and mechanical parameters are identical.

Q: Which part should I specify for new designs?

A: Selection depends on applicable regulatory requirements. For applications subject to RoHS3 or REACH regulations, specify CD10ED430JO3F. For applications without such requirements, either part is acceptable based on availability and cost considerations.

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

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

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

A: Lead spacing is specified as 0.142" (3.60 mm) for both parts. This dimension is critical for PCB hole pattern compatibility and through-hole assembly.
