Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5NR331KABCA is determined by the following critical parameters:

• Capacitance Value: 330 pF (exact match required)
• Voltage Rating: 1000V minimum (equal or higher acceptable)
• Tolerance: ±10% (matching tolerance class)
• Mounting Configuration: Through-hole radial, disc package
• Lead Spacing: 0.197" (5.00mm) for PCB compatibility
• Temperature Coefficient: Y5F or equivalent performance class

The substitute part 562RTST33 meets these core electrical and mechanical requirements, with the primary distinction being the temperature coefficient classification (X7R vs. Y5F) and expanded operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The 562RTST33 serves as a functional equivalent for the obsolete 5NR331KABCA based on matching electrical specifications: identical capacitance (330 pF), tolerance (±10%), and voltage rating (1000V). Both components maintain compatible lead spacing (0.197" / 5.00mm) for through-hole PCB mounting.

The substitute part offers extended product availability as an active component from Vishay Cera-Mite, with ROHS3 compliance certification. The X7R temperature coefficient provides a wider operating temperature range (-55°C ~ 105°C) compared to the Y5F specification (-30°C ~ 85°C), which may provide additional thermal margin in applications.

Physical dimensions differ: the 562RTST33 has a larger diameter (0.252" vs. 0.197") and greater seated height (0.370" vs. 0.157"), requiring verification of available PCB space and component clearance in the target assembly.

Frequently Asked Questions (FAQ)

Q: Can the 562RTST33 directly replace the 5NR331KABCA in existing designs?

A: Electrical substitution is valid based on matching capacitance, tolerance, and voltage rating. Physical layout verification is required due to increased component dimensions (diameter and height). PCB footprint and clearance must be confirmed before implementation.

Q: What is the significance of the temperature coefficient difference (Y5F vs. X7R)?

A: Y5F and X7R are temperature coefficient classifications for ceramic capacitors. X7R provides tighter capacitance stability across temperature (-55°C to +105°C) compared to Y5F (-30°C to +85°C). The substitute part's X7R rating may offer improved performance stability in temperature-sensitive applications.

Q: Are there compliance or regulatory differences between these parts?

A: The 562RTST33 carries ROHS3 compliance certification. Both parts maintain REACH Unaffected status and EAR99 ECCN classification. Compliance requirements for the target application should be verified.

Q: Does lead spacing compatibility ensure PCB mounting compatibility?

A: Matching lead spacing (0.197" / 5.00mm) confirms through-hole pad compatibility. However, the larger body diameter and height of the 562RTST33 may require clearance verification to prevent interference with adjacent components or board features.

Q: What inventory considerations apply to this substitution?

A: The 5NR331KABCA is obsolete with limited stock availability. The 562RTST33 is an active product with established supply channels, supporting long-term design continuity and procurement reliability.
