Frequently Asked Questions (FAQ)

Q: Can CS45-B2GA471K-NKA be used as a direct replacement for CS45-B2GA471K-GKA?

A: Yes. Both parts are identical in electrical specifications (470 pF, ±10%, 440VAC), temperature coefficient (B), operating temperature range (-25°C ~ 125°C), and mechanical configuration (Through Hole, Radial Disc, 7.00mm diameter, 7.50mm lead spacing). They share the same safety ratings (X1, Y2) and regulatory compliance (ROHS3).

Q: Are there any differences in lead formation or packaging between these parts?

A: No. Both parts feature Formed Leads - Kinked configuration and are supplied in Bulk packaging. Physical dimensions and lead spacing are identical.

Q: Do both parts meet the same safety and compliance standards?

A: Yes. Both parts carry X1, Y2 safety ratings and are ROHS3 compliant. The CS45-B2GA471K-NKA additionally carries REACH Unaffected status.

Q: What is the basis for substitution between these two part numbers?

A: Substitution is based on complete equivalence across capacitance value, voltage rating, tolerance, temperature coefficient, operating temperature range, mounting type, package configuration, lead style, and safety certifications. No electrical or mechanical parameters differ between the two parts.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Identical through-hole mounting specifications, lead spacing (0.295" / 7.50mm), and component dimensions ensure direct PCB compatibility without layout modifications.
