Substitute Part Grouping Explanation

Substitute parts for the CAS18C222KARGC are qualified based on strict equivalence across the following critical parameters:

• Capacitance value: 2200 pF
• Tolerance: ±10%
• Rated voltage: 250VAC
• Temperature coefficient: X7R
• Safety rating: X2
• Package: 1812 (4532 Metric)
• Mounting type: Surface Mount, MLCC
• Operating temperature range: -55°C ~ 125°C
• Compliance certifications: ROHS3 Compliant, REACH Unaffected, EAR99

Two substitute parts meet these criteria: SAFC1812X7R202-222KNE (Venkel) and KGH43JR73E222KV (KYOCERA AVX). Both components maintain identical electrical specifications and safety classifications, with minor dimensional variations within acceptable tolerances for the 1812 package form factor.

Parameter Comparison

Engineering Selection Recommendations

All three components—CAS18C222KARGC, SAFC1812X7R202-222KNE, and KGH43JR73E222KV—are active products with full ROHS3 compliance and REACH unaffected status. Selection among these parts should be based on availability, lead time, and procurement cost, as electrical and safety specifications are equivalent. The SAFC1812X7R202-222KNE exhibits a slightly reduced maximum thickness (0.102" vs. 0.110"), which may be advantageous in space-constrained applications. The KGH43JR73E222KV maintains identical dimensions to the original CAS18C222KARGC, ensuring direct mechanical compatibility without PCB layout modifications.

Frequently Asked Questions (FAQ)

Q: Can SAFC1812X7R202-222KNE be used as a direct replacement for CAS18C222KARGC?

A: Yes. Both components share identical electrical specifications (2200 pF, ±10%, 250VAC, X7R, X2 rating) and package classification (1812 Metric). The SAFC variant has a slightly larger length (0.181" vs. 0.177") and reduced thickness (0.102" vs. 0.110"), which are within acceptable tolerances for the 1812 package form factor and do not affect electrical performance.

Q: What is the difference between KGH43JR73E222KV and the original CAS18C222KARGC?

A: The KGH43JR73E222KV is a parametric equivalent with identical electrical specifications and physical dimensions. The primary difference is the manufacturer (KYOCERA AVX vs. KEMET). Both components are active products with equivalent compliance certifications.

Q: Are all three parts suitable for safety-critical applications?

A: Yes. All three components carry the X2 safety rating and are classified for safety applications. Each maintains ROHS3 compliance and EAR99 export classification.

Q: Does the thickness variation between parts affect PCB assembly?

A: The thickness variation (0.102" to 0.110") is within standard 1812 package tolerances and does not affect reflow soldering or component placement. PCB design accommodations are not required.

Q: What is the moisture sensitivity level for these components?

A: All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
