ECK-ANA332ME Equivalent & Substitute Parts

Part Overview

The ECK-ANA332ME is a 3300 pF ceramic capacitor rated for 440VAC with Y5U temperature coefficient, manufactured by Panasonic Electronic Components. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. 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 for the ECK-ANA332ME is determined by the following critical parameters:

• Capacitance value: 3300 pF (exact match required)
• Tolerance: ±20% (exact match required)
• Temperature Coefficient: Y5U (E) (exact match required)
• Safety Ratings: X1, Y1 (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Disc (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)

Voltage rating may vary within acceptable design margins for the application, provided the substitute meets or exceeds the minimum voltage requirement of the original circuit. Operating temperature range and physical dimensions are secondary considerations when primary electrical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts meet the core electrical specifications of the ECK-ANA332ME. Selection between C951U332MUWDBA7317 and VY1332M59Y5UQ63V0 depends on circuit voltage margin requirements:

The C951U332MUWDBA7317 (KEMET) operates at 400VAC, which is below the original 440VAC rating. This part is suitable only for applications where the actual operating voltage does not exceed 400VAC.

The VY1332M59Y5UQ63V0 (Vishay) operates at 760VAC, exceeding the original 440VAC specification. This part provides additional voltage margin and is suitable for all applications originally designed for the ECK-ANA332ME.

Both substitute parts are RoHS3 compliant and REACH unaffected, with active product status ensuring long-term availability. The Vishay part offers superior voltage headroom and extended operating temperature range (-40°C minimum versus -25°C).

Frequently Asked Questions (FAQ)

Q: Can C951U332MUWDBA7317 replace ECK-ANA332ME in all applications?

A: No. The KEMET part is rated for 400VAC, which is 40VAC below the original specification. Use only in applications where operating voltage does not exceed 400VAC.

Q: Is VY1332M59Y5UQ63V0 a direct replacement?

A: Yes. The Vishay part matches all critical electrical parameters and exceeds the voltage rating. Physical dimensions differ slightly (15.00mm diameter versus 13.00mm), but lead spacing and mounting type remain compatible.

Q: What is the significance of the Y5U temperature coefficient?

A: Y5U specifies capacitance change limits across the operating temperature range. All three parts share this specification, ensuring equivalent thermal performance.

Q: Are both substitutes suitable for safety-critical applications?

A: Yes. Both substitute parts carry X1, Y1 safety ratings identical to the original part, qualifying them for safety applications.

Q: Does packaging format affect substitution?

A: The KEMET part is supplied in Tape & Box format, while Vishay is supplied in Bulk. Both are compatible with through-hole assembly processes. Verify packaging compatibility with your procurement and assembly requirements.
