ECK-ATS332ME Equivalent & Substitute Parts

Part Overview

The Panasonic ECK-ATS332ME is a 3300 pF ceramic capacitor rated for 440VAC with Y5U temperature coefficient, designed for safety-critical applications. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance requirements. The part features X1, Y2 safety ratings and is suitable for through-hole mounting in radial disc configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Capacitance Value: Must be 3300 pF
• Tolerance: Must be ±20%
• Temperature Coefficient: Must be Y5U (E)
• Safety Ratings: Must include X1, Y2
• Mounting Type: Must be Through Hole
• Package Type: Must be Radial, Disc

Voltage rating substitution is permitted when the substitute part meets or exceeds the original 440VAC specification. Lead spacing and physical dimensions may vary within the constraints of through-hole radial disc packaging, provided mechanical compatibility is maintained in the target application.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Preferred)

VY2332M41Y5US65V7 and VY2332M41Y5US63V7 from Vishay are direct functional equivalents. Both maintain the 440VAC voltage rating, matching the original specification. Both are active products with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory alignment. The extended operating temperature range (-40°C ~ 125°C) provides improved performance margin compared to the original part.

Functional Alternatives

C941U332MYWDBA7317 and C947U332MYWDBA7317 from KEMET meet all critical electrical parameters but operate at 400VAC. These parts are suitable for applications where the circuit voltage does not exceed 400VAC. Both are active products with ROHS3 compliance. The primary distinction between these KEMET options is packaging format: C941U332MYWDBA7317 is supplied in Tape & Box format, while C947U332MYWDBA7317 is supplied in Cut Tape format with significantly higher inventory availability.

Frequently Asked Questions (FAQ)

Q: Can I use a 400VAC rated substitute in place of the 440VAC original?

A: Only if your circuit operates at or below 400VAC. The KEMET parts (C941U332MYWDBA7317 and C947U332MYWDBA7317) are rated for 400VAC and must not be used in circuits requiring 440VAC operation. The Vishay parts maintain the 440VAC rating and are preferred for direct replacement.

Q: What is the difference between VY2332M41Y5US65V7 and VY2332M41Y5US63V7?

A: Both parts are electrically and mechanically identical. The difference lies in the suffix designation within the Vishay part numbering system. Both are active products with equivalent availability and specifications.

Q: Are there packaging differences between the KEMET substitutes?

A: Yes. C941U332MYWDBA7317 is supplied in Tape & Box (TB) packaging, while C947U332MYWDBA7317 is supplied in Cut Tape (CT) packaging. C947U332MYWDBA7317 has significantly higher inventory (9150 pcs vs. 994 pcs). Select based on your assembly process requirements and volume needs.

Q: Do all substitutes meet the same safety certifications?

A: Yes. All substitute parts maintain X1, Y2 safety ratings required for the original application. The Vishay and KEMET parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the impact of the extended operating temperature range in substitute parts?

A: The substitute parts operate from -40°C to 125°C compared to the original -25°C to 125°C. This extended lower temperature limit provides additional performance margin and is not a limitation for applications designed for the original part.

Q: Can I mix different substitute parts in the same assembly?

A: Yes, provided all parts meet the circuit voltage requirements. For 440VAC circuits, use only Vishay parts. For 400VAC or lower circuits, KEMET parts are acceptable. Mixing is permissible from a functional standpoint, though standardizing on a single substitute part is recommended for inventory management.
