ECK-A3D471KBP Equivalent & Substitute Parts

Part Overview

The ECK-A3D471KBP is a 470 pF ceramic capacitor rated for 2000V (2kV) 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. Vishay Beyschlag/Draloric/BC Components offers multiple active alternatives that maintain electrical and mechanical compatibility within the specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the ECK-A3D471KBP is determined by strict equivalence across the following critical parameters:

Capacitance value: 470 pF
Tolerance: ±10%
Voltage rating: 2000V (2kV)
Temperature coefficient: Y5P (B)
Package configuration: Radial, Disc
Physical dimensions: 0.295" Dia (7.50mm)
Mounting type: Through Hole

All qualified substitutes maintain these core electrical and mechanical specifications. Variations in lead spacing (0.197" vs 0.295") and lead style (Formed Leads vs Formed Leads - Kinked) represent secondary design considerations that do not affect electrical performance but may impact PCB layout compatibility. Packaging format (Bulk vs Tape & Reel) and inventory availability are procurement variables independent of functional equivalence.

Engineering Selection Recommendations

All four Vishay Beyschlag/Draloric/BC Components substitutes (S471K29Y5PP63K5R, S471K29Y5PP63L5R, S471K29Y5PP6TK5R, S471K29Y5PP6TK7R) are active products with ROHS3 compliance and REACH unaffected status, providing regulatory continuity for new designs and production runs.

Selection between substitutes depends on PCB layout requirements and procurement format:

For designs with 7.50mm lead spacing (matching original ECK-A3D471KBP footprint), use S471K29Y5PP6TK7R. This part maintains identical lead spacing and requires no PCB layout modification.

For designs accommodating 5.00mm lead spacing, S471K29Y5PP63K5R, S471K29Y5PP63L5R, or S471K29Y5PP6TK5R are suitable. These parts offer higher inventory availability and flexible packaging options (Bulk or Tape & Reel).

All substitutes provide expanded operating temperature range (-30°C to 125°C versus -25°C to 125°C), offering improved thermal margin in applications approaching temperature extremes.

Frequently Asked Questions (FAQ)

Q: Can S471K29Y5PP6TK7R be used as a direct replacement without PCB modification?

A: Yes. S471K29Y5PP6TK7R maintains the 0.295" (7.50mm) lead spacing of the original ECK-A3D471KBP, enabling direct PCB footprint compatibility without layout changes.

Q: What is the difference between the Vishay substitutes with 5.00mm and 7.50mm lead spacing?

A: Lead spacing affects PCB hole pattern and component placement. The 5.00mm lead spacing variants (S471K29Y5PP63K5R, S471K29Y5PP63L5R, S471K29Y5PP6TK5R) require PCB redesign if the original design used 7.50mm spacing. Electrical performance is identical across all variants.

Q: Are Bulk and Tape & Reel packaging options electrically equivalent?

A: Yes. Packaging format (Bulk versus Tape & Reel) is a procurement and handling specification only. Electrical and mechanical parameters remain identical. Selection depends on assembly process requirements and order quantity.

Q: Does the kinked lead style of Vishay parts affect circuit performance?

A: No. Lead style (Formed Leads versus Formed Leads - Kinked) is a mechanical design feature that does not alter electrical characteristics. Kinked leads may provide improved mechanical retention during assembly but do not affect capacitance, voltage rating, or temperature coefficient.

Q: Why do Vishay substitutes have a wider operating temperature range?

A: Vishay parts specify -30°C to 125°C versus the original -25°C to 125°C. This represents a design specification difference between manufacturers and provides additional thermal margin. Both ranges satisfy Y5P temperature coefficient requirements.

Q: Are all substitutes RoHS compliant?

A: Yes. All four Vishay substitutes are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronics manufacturing.
