ECK-A3A103KBP Equivalent & Substitute Parts

Part Overview

The ECK-A3A103KBP is a 10000 pF ceramic capacitor rated at 1000V with Y5P temperature coefficient, manufactured by Panasonic Electronic Components in radial disc configuration. This part is classified as obsolete, making substitute identification necessary for ongoing design support and procurement continuity. The radial through-hole mounting and high-voltage rating position this component for general-purpose applications requiring reliable capacitance in legacy or new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECK-A3A103KBP is determined by the following criteria:

Primary Matching Parameters:

• Capacitance value: 10000 pF (exact match required)
• Tolerance: ±10% (standard tolerance maintained)
• Mounting type: Through Hole (mechanical compatibility)
• Lead style: Straight (board layout compatibility)

Allowable Variation Parameters:

• Voltage rating: May exceed 1000V (higher voltage provides design margin and reliability)
• Temperature coefficient: X7R acceptable as alternative to Y5P (both suitable for general-purpose applications)
• Operating temperature range: May extend beyond -25°C ~ 125°C (wider range provides additional operational flexibility)
• Physical dimensions: May differ within radial package constraints (board space permitting)

The SV05HC103KAR qualifies as a substitute based on matching capacitance, tolerance, mounting type, and lead style, while providing enhanced voltage rating (3000V) and extended temperature range (-55°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

The SV05HC103KAR from KYOCERA AVX is a qualified substitute for the obsolete ECK-A3A103KBP. Selection is supported by:

• Functional equivalence: Identical capacitance and tolerance values ensure electrical performance parity
• Enhanced reliability: 3000V rating provides 3× voltage margin over the original 1000V specification
• Extended temperature range: -55°C lower bound supports broader environmental applications
• Active product status: Ensures long-term availability and supply chain continuity
• Compliance certifications: ROHS3 compliance and REACH unaffected status meet current regulatory requirements
• Mechanical compatibility: Through-hole radial configuration with straight leads maintains board-level integration without redesign

Physical dimensions differ (0.469" L × 0.200" W vs. 0.866" Dia), requiring board layout verification for space constraints.

Frequently Asked Questions (FAQ)

Q: Can the SV05HC103KAR directly replace the ECK-A3A103KBP without circuit modification?

A: Yes, for circuits designed around the original 1000V specification. The substitute's higher voltage rating (3000V) and X7R temperature coefficient are compatible with general-purpose applications. Board layout must accommodate the different physical dimensions.

Q: What is the significance of the voltage rating difference (1000V vs. 3000V)?

A: The substitute provides enhanced voltage margin. Circuits operating at or below 1000V will function identically. The higher rating increases component reliability and lifespan under electrical stress.

Q: How do the temperature coefficients Y5P and X7R differ in application?

A: Both are suitable for general-purpose use. Y5P exhibits ±10% capacitance change over temperature; X7R exhibits ±15% change. For applications requiring tighter capacitance stability, circuit performance should be evaluated against actual operating conditions.

Q: Are there physical space considerations when substituting?

A: Yes. The ECK-A3A103KBP is 0.866" diameter (disc); the SV05HC103KAR is 0.469" L × 0.200" W (rectangular radial). Verify board layout accommodates the substitute's footprint and lead spacing (9.52mm vs. 10.00mm).

Q: Is the substitute RoHS compliant?

A: The SV05HC103KAR is ROHS3 compliant and REACH unaffected. Original part compliance status was not specified in available documentation.
