ECK-A3F471KBP Equivalent & Substitute Parts

Part Overview

The ECK-A3F471KBP is a 470 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 equivalent substitute parts necessary for ongoing design support and procurement continuity. Substitute parts must maintain identical electrical specifications (capacitance, voltage rating, tolerance, temperature coefficient) and compatible mechanical dimensions for through-hole radial mounting applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECK-A3F471KBP is determined by strict equivalence across the following parameters:

• Capacitance value: 470 pF (exact match required)
• Voltage rating: 3000V minimum (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: Y5P (B) (exact match required)
• Mounting type: Through Hole radial configuration (exact match required)
• Lead configuration: Formed leads compatible with standard PCB hole spacing

All substitute parts listed are manufactured by Vishay Beyschlag/Draloric/BC Components under the S-series designation. These parts maintain full electrical equivalence to the original Panasonic component while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

All three Vishay substitute parts (S471K33Y5PR63K6R, S471K33Y5PR63K7R, S471K33Y5PR65K7R) provide full electrical equivalence to the ECK-A3F471KBP. Selection among these options is determined by mechanical fit requirements:

S471K33Y5PR63K6R features a 0.252" (6.40mm) lead spacing and 0.335" (8.50mm) diameter body, suitable for compact PCB layouts with tighter component spacing.

S471K33Y5PR63K7R and S471K33Y5PR65K7R both feature 0.295" (7.50mm) lead spacing, matching the original ECK-A3F471KBP lead spacing of 0.295" (7.50mm), and are recommended for direct board-level replacement without PCB modification. Both maintain 0.335" (8.50mm) diameter bodies.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting modern environmental and regulatory requirements. The Vishay parts operate across -30°C to 125°C, providing extended low-temperature performance compared to the original -25°C to 125°C range.

Frequently Asked Questions (FAQ)

Q: Can S471K33Y5PR63K6R be used as a direct replacement for ECK-A3F471KBP?

A: S471K33Y5PR63K6R is electrically equivalent but features different lead spacing (6.40mm vs. 7.50mm). Direct PCB replacement requires lead spacing compatibility. Verify PCB hole pattern before selection.

Q: What is the difference between the three Vishay substitute parts?

A: All three parts are electrically identical (470 pF, 3kV, Y5P, ±10%). The primary difference is lead spacing: S471K33Y5PR63K6R uses 6.40mm spacing, while S471K33Y5PR63K7R and S471K33Y5PR65K7R use 7.50mm spacing matching the original part. Body diameter remains 8.50mm for all three.

Q: Are the Vishay substitutes suitable for high-temperature applications?

A: Yes. All substitute parts maintain the Y5P temperature coefficient and operate across -30°C to 125°C, covering the original operating range and extending to lower temperatures.

Q: Do the substitute parts meet current compliance standards?

A: Yes. All Vishay substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for new designs and procurement.

Q: What is the lead style difference between the original and substitutes?

A: The ECK-A3F471KBP uses standard formed leads, while Vishay substitutes use formed leads with kinked configuration. Both are compatible with standard through-hole PCB mounting; kinked leads provide improved mechanical retention during assembly.
