Frequently Asked Questions (FAQ)

Q: Can the SAFC1808X7R202-152KNE be used as a direct replacement for the CAS17C152KARGC?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (1500 pF), voltage rating (250VAC), temperature coefficient (X7R), tolerance (±10%), package designation (1808), and safety rating (X2). Physical dimensions are compatible within standard assembly tolerances.

Q: Are there any differences in the physical dimensions between these parts?

A: Minor dimensional variations exist. The CAS17C152KARGC measures 0.177" L × 0.080" W (4.50mm × 2.03mm), while the SAFC1808X7R202-152KNE measures 0.181" L × 0.079" W (4.60mm × 2.00mm). Both have identical maximum thickness of 0.087" (2.20mm). These variations are within standard PCB assembly tolerances and do not affect functionality or mounting compatibility.

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

A: Yes. Both the CAS17C152KARGC and SAFC1808X7R202-152KNE are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. Both are classified with X2 safety ratings for safety applications.

Q: What is the operating temperature range for these capacitors?

A: Both parts operate across the identical temperature range of -55°C to 125°C with X7R temperature coefficient characteristics, ensuring stable capacitance performance throughout this range.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The electrical specifications, package footprint, and safety ratings are identical. No design modifications are required for substitution. Standard PCB assembly processes apply to both parts.

Q: What is the significance of the X7R temperature coefficient?

A: X7R indicates that capacitance variation is limited to ±15% across the -55°C to 125°C operating range. This provides stable performance across wide temperature variations, making these parts suitable for industrial and safety-critical applications.
