CAS26C151KAGFC Equivalent & Substitute Parts

Part Overview

The CAS26C151KAGFC is a 150 pF ±10% 250VAC ceramic capacitor manufactured by KEMET, classified as a safety-rated component with C0G/NP0 temperature coefficient. This Surface Mount MLCC (Multilayer Ceramic Capacitor) in 2211 (5728 Metric) package is designed for safety applications requiring X1, Y2 ratings. The part is currently in Active product status with 673 units available in stock. Substitute parts become necessary when primary inventory is depleted, when supply chain constraints occur, or when design flexibility across qualified manufacturers is required while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAS26C151KAGFC is determined by strict equivalence across the following critical parameters:

• Capacitance value: 150 pF
• Tolerance: ±10%
• Voltage rating: 250VAC
• Temperature coefficient: C0G, NP0
• Safety ratings: X1, Y2
• Package type: 2211 (5728 Metric)
• Mounting configuration: Surface Mount, MLCC
• Operating temperature range: -55°C ~ 125°C
• RoHS3 compliance

The substitute part ES2211N151K502NTM from Knowles Novacap meets all electrical and mechanical requirements for direct substitution. Both parts share identical capacitance, tolerance, voltage rating, temperature coefficient, safety ratings, and package specifications. Physical dimensions are within acceptable tolerance for the same package classification.

Parameter Comparison

Engineering Selection Recommendations

The CAS26C151KAGFC from KEMET is the primary selection for new designs, as it maintains Active product status and demonstrates ongoing manufacturer support. The ES2211N151K502NTM from Knowles Novacap is classified as Not For New Designs but remains a valid substitute for existing applications, maintenance, or when KEMET inventory is unavailable.

Both parts satisfy ROHS3 compliance requirements. The KEMET part carries REACH Unaffected status, while the Knowles Novacap part is REACH Affected. For applications subject to REACH regulations, this distinction may influence procurement decisions. Both components are rated for safety applications with X1, Y2 classifications and operate across the full -55°C to 125°C temperature range.

Physical dimensions between the two parts are equivalent within standard manufacturing tolerances for the 2211 package classification, ensuring PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can ES2211N151K502NTM be used as a direct replacement for CAS26C151KAGFC?

A: Yes. Both parts share identical electrical specifications (150 pF, ±10%, 250VAC, C0G/NP0), safety ratings (X1, Y2), package type (2211), and operating temperature range (-55°C ~ 125°C). Physical dimensions are within acceptable tolerance for the same package classification.

Q: What is the significance of "Not For New Designs" status on the Knowles Novacap part?

A: This designation indicates the manufacturer is not actively promoting the part for new product development. However, it remains functionally equivalent and suitable for existing applications or as a substitute when primary inventory is constrained.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity. The KEMET part is REACH Unaffected, while the Knowles Novacap part is REACH Affected. Applications subject to REACH regulations should account for this distinction during procurement planning.

Q: Will the dimensional differences affect PCB assembly?

A: No. The dimensional variance (KEMET: 5.70mm x 2.80mm vs. Knowles Novacap: 5.58mm x 2.79mm) falls within standard manufacturing tolerances for the 2211 (5728 Metric) package classification and does not require PCB layout modification.

Q: What packaging format is available for both parts?

A: Both parts are supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
