CAS17C331KARGC Equivalent & Substitute Parts

Part Overview

The CAS17C331KARGC is a 330 pF ±10% 250VAC ceramic capacitor manufactured by KEMET, classified as a safety-rated (X2) component in the 1808 (4520 Metric) package. This multilayer ceramic capacitor (MLCC) is designed for surface mount applications requiring X7R temperature stability across -55°C to 125°C operating range. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications where this specific manufacturer's part may be unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAS17C331KARGC is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 pF
• Tolerance: ±10%
• Voltage rating: 250VAC minimum
• Temperature coefficient: X7R
• Safety rating: X2
• Package: 1808 (4520 Metric)
• Mounting type: Surface Mount, MLCC
• Compliance: ROHS3 Compliant

The substitute part SAFC1808X7R202-331KNE (Venkel) meets all mandatory electrical and mechanical specifications. Physical dimensions show minor variations within acceptable tolerances for the 1808 package class. Both parts maintain identical electrical performance characteristics and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the CAS17C331KARGC and SAFC1808X7R202-331KNE are active production parts with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

• Availability and lead time requirements
• Procurement cost and volume pricing
• Existing supplier relationships and qualification status
• PCB assembly process compatibility with minor dimensional variations in the 1808 package

The Venkel substitute (SAFC1808X7R202-331KNE) provides functional equivalence with higher current inventory availability (6736 pcs vs. 908 pcs), supporting expedited procurement scenarios.

Frequently Asked Questions (FAQ)

Q: Can SAFC1808X7R202-331KNE be used as a direct replacement for CAS17C331KARGC?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 330 pF capacitance, ±10% tolerance, 250VAC rating, X7R temperature coefficient, X2 safety rating, and 1808 package format. Both maintain ROHS3 compliance and MSL 1 rating.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within the 1808 package class. CAS17C331KARGC measures 4.50mm L × 2.03mm W × 1.80mm thickness; SAFC1808X7R202-331KNE measures 4.60mm L × 2.00mm W × 2.20mm thickness. These variations are within standard 1808 package tolerances and do not affect PCB layout or assembly compatibility.

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

A: Yes. Both parts carry X2 safety rating for AC applications, ROHS3 compliance, and EAR99 export classification. Moisture sensitivity level is identical (MSL 1, Unlimited).

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on supplier availability, cost, and existing qualification status within your organization's supply chain.
