ECK-A3F222KBP Equivalent & Substitute Parts

Part Overview

The ECK-A3F222KBP is a 2200 pF ceramic capacitor rated for 3000V (3kV) with Y5P temperature coefficient, manufactured by Panasonic Electronic Components in radial disc configuration. This part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

The primary reason for identifying substitute parts is the obsolete status of the original Panasonic component. Active equivalent parts with identical electrical specifications ensure design continuity and system reliability in applications requiring high-voltage ceramic capacitors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECK-A3F222KBP is determined by strict equivalence across the following critical parameters:

• Capacitance value: 2200 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 3000V minimum (equal or higher acceptable)
• Temperature coefficient: Y5P (B) (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial, Disc (exact match required)

The substitute part S222K59Y5PR63K7R meets all substitution criteria. Both parts share identical electrical specifications and mechanical mounting requirements, with the substitute part maintaining active product status and full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The S222K59Y5PR63K7R is a direct functional equivalent to the ECK-A3F222KBP. Selection of this substitute part is supported by:

• Identical electrical specifications (capacitance, tolerance, voltage rating, temperature coefficient)
• Matching mechanical configuration (through-hole radial disc package)
• Active product status ensuring long-term availability
• ROHS3 compliance and REACH unaffected status providing regulatory alignment
• Extended lower operating temperature limit (-30°C vs. -25°C) offering broader environmental compatibility

Physical dimensions differ slightly between the two parts. The Panasonic original measures 0.669" diameter with 0.394" lead spacing, while the Vishay substitute measures 0.591" diameter with 0.295" lead spacing. PCB layout verification is necessary to confirm mechanical fit within existing designs.

Frequently Asked Questions (FAQ)

Q: Can the S222K59Y5PR63K7R be used as a direct replacement for the ECK-A3F222KBP?

A: Yes, the S222K59Y5PR63K7R meets all electrical substitution criteria. Both parts share identical capacitance (2200 pF), tolerance (±10%), voltage rating (3000V), and temperature coefficient (Y5P). Physical dimensions differ, requiring PCB layout verification for mechanical compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are physical dimensions and lead configuration. The Vishay part features kinked formed leads and smaller overall dimensions (0.591" diameter vs. 0.669"). The Vishay part also provides ROHS3 compliance and a lower minimum operating temperature (-30°C vs. -25°C).

Q: Is the operating temperature range difference significant?

A: The Vishay substitute extends the lower operating temperature to -30°C compared to the Panasonic original at -25°C. Both parts maintain the same upper temperature limit of 125°C. This difference is not significant for most applications and represents an improvement in environmental tolerance.

Q: What should be verified before implementing this substitution?

A: Verify PCB layout compatibility with the smaller physical dimensions and different lead spacing of the Vishay part. Confirm that the kinked lead style accommodates existing mounting holes and component placement requirements.

Q: Are there any compliance or regulatory considerations?

A: The Vishay substitute is ROHS3 compliant and REACH unaffected, providing regulatory alignment for modern manufacturing and distribution requirements. The original Panasonic part does not specify these certifications.
