Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching key parameters including capacitance, tolerance, voltage rating, temperature coefficient, X1/Y2 safety ratings, package/case size (2211, 5728 Metric), surface mount type, and regulatory compliance (RoHS3, MSL 1). Only parts meeting all these criteria qualify for direct replacement without deviation from required standards or form factor.

Key substitution parameters:

• Capacitance: 330 pF
• Tolerance: ±10%
• Voltage Rating: 250VAC
• Temperature Coefficient: X7R
• Safety Ratings: X1, Y2
• Package/Case: 2211 (5.70mm x 2.80mm), 0.071" (1.80mm) thickness max
• Mounting Type: Surface Mount, MLCC
• Compliance: RoHS3, MSL 1

Parameter Comparison

Frequently Asked Questions (FAQ)

Q1: What key parameters define interchangeability for safety capacitors in this category?
A1: Interchangeability is defined by matching capacitance, tolerance, AC voltage rating, temperature coefficient, X1/Y2 safety ratings, physical package size (2211), and mounting style. Regulatory compliance (RoHS, REACH, MSL) must also be identical.

Q2: Are the KEMET CAS26C331KARFC and Murata GA352QR7GF331KW31L footprint-compatible?
A2: Both components have the same package (2211, 5728 Metric), identical physical dimensions (0.224" x 0.110"), and maximum thickness (0.071"/1.80mm), making them footprint-compatible.

Q3: Can the substitute be used in the same safety-critical AC line suppression applications?
A3: Both parts carry X1/Y2 safety ratings and a 250VAC voltage rating, making them suitable for equivalent application use based on provided parameters.

Q4: Are RoHS and REACH statuses matched between these parts?
A4: Both parts are RoHS3 compliant and REACH unaffected, allowing use in applications with these regulatory requirements.

Q5: Does substituting with the Murata GA352QR7GF331KW31L affect moisture sensitivity handling?
A5: Both parts have an MSL 1 (unlimited) rating, ensuring no change in handling or storage conditions concerning moisture sensitivity.
