ECK-ANA101MB Equivalent & Substitute Parts

Part Overview

The ECK-ANA101MB is a 100 pF ceramic capacitor rated for 440VAC with Y5P temperature coefficient, manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part is designed for safety-critical applications with X1, Y1 ratings and operates across a temperature range of -25°C to 125°C in radial, disc configuration with through-hole mounting.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECK-ANA101MB is determined by the following critical parameters:

• Capacitance Value: 100 pF (exact match required)
• Voltage Rating: Minimum 440VAC (equal or higher acceptable)
• Temperature Coefficient: Y5P or Y5S (both acceptable for safety applications)
• Mounting Configuration: Through-hole radial, disc package with 0.394" (10.00mm) lead spacing
• Safety Ratings: X1, Y1 compliance required
• Operating Temperature Range: Must support -25°C to 125°C minimum

The substitute part VY1101K31Y5SQ6XT0 meets these criteria with equivalent capacitance, higher voltage rating (760VAC), compatible temperature coefficient (Y5S), matching lead spacing, and identical safety ratings. The substitute maintains through-hole radial mounting and supports the required operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The VY1101K31Y5SQ6XT0 is a direct substitute for the obsolete ECK-ANA101MB. The substitute part offers improved specifications including higher voltage rating (760VAC vs. 440VAC), tighter tolerance (±10% vs. ±20%), and extended lower temperature operating range (-40°C vs. -25°C). Both parts maintain identical lead spacing (10.00mm), through-hole radial mounting, and X1, Y1 safety ratings required for the application.

The substitute part is currently in active production status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory compliance. The substitute's higher voltage rating provides additional design margin without affecting circuit performance in applications originally specified for 440VAC operation.

Frequently Asked Questions (FAQ)

Q: Can VY1101K31Y5SQ6XT0 be used as a direct replacement for ECK-ANA101MB?

A: Yes. Both parts share identical capacitance (100 pF), lead spacing (10.00mm), mounting type (through-hole radial), and safety ratings (X1, Y1). The substitute's higher voltage rating and tighter tolerance represent improvements over the original specification.

Q: What are the physical compatibility considerations?

A: Both parts use radial, disc package configuration with 0.394" (10.00mm) lead spacing and through-hole mounting. The substitute has a smaller body diameter (0.315" vs. 0.433"), which may reduce PCB footprint requirements but does not affect electrical compatibility or mounting hole spacing.

Q: Are there temperature range differences that affect application suitability?

A: The substitute supports -40°C to 125°C versus the original -25°C to 125°C. This extended lower temperature range provides additional operational margin and does not restrict use in applications originally specified for the ECK-ANA101MB.

Q: How do tolerance differences impact circuit performance?

A: The substitute's ±10% tolerance is tighter than the original ±20%. For 100 pF capacitance, this represents a maximum deviation of ±10 pF versus ±20 pF. In safety-critical filtering applications, the improved tolerance may enhance circuit stability without requiring design modifications.

Q: What is the significance of the Y5P versus Y5S temperature coefficient difference?

A: Both Y5P and Y5S are acceptable temperature coefficients for safety-rated ceramic capacitors in this application category. Y5S represents a slightly different temperature stability characteristic but maintains compatibility with X1, Y1 safety ratings and the specified operating temperature range.
