ECK-ATS102ME Equivalent & Substitute Parts

Part Overview

The Panasonic ECK-ATS102ME is a 1000 pF ceramic capacitor rated for 440VAC with Y5U temperature coefficient, designed for safety-critical applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance requirements. The ECK-ATS102ME features X1, Y2 safety ratings and is suitable for through-hole mounting in radial disc configurations.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Capacitance Value: Must be 1000 pF
Tolerance: Must be ±20%
Temperature Coefficient: Must be Y5U (E)
Safety Ratings: Must include X1, Y2
Mounting Type: Must be Through Hole
Package / Case: Must be Radial, Disc

Upgrade Substitutes (VY2102M29Y5UG63V7, VY2102M29Y5US63V7, VY2102M29Y5US6TV7) meet all critical parameters with identical electrical specifications and active product status. These Vishay Beyschlag/Draloric/BC Components parts maintain 440VAC rating and Y5U temperature coefficient with extended operating temperature range (-40°C ~ 125°C).

Similar Substitutes (C901U102MYWDBA7317, C907U102MYWDBA7317) are KEMET parts that match capacitance, tolerance, temperature coefficient, and safety ratings. These parts are rated for 400VAC instead of 440VAC, representing a voltage derating that may be acceptable depending on circuit design margins.

Engineering Selection Recommendations

Upgrade Substitutes (Vishay VY2 Series) are the primary recommendation for direct replacement of the obsolete ECK-ATS102ME. All three Vishay parts maintain identical electrical specifications at 440VAC rating with Y5U temperature coefficient and X1, Y2 safety certifications. These parts carry active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

The three Vishay variants differ only in packaging format: VY2102M29Y5UG63V7 and VY2102M29Y5US63V7 are supplied in bulk packaging, while VY2102M29Y5US6TV7 is supplied in cut tape format. Selection between these should be based on procurement and assembly requirements.

Similar Substitutes (KEMET C900AC Series) are acceptable alternatives where circuit design permits 400VAC operation. Both C901U102MYWDBA7317 and C907U102MYWDBA7317 maintain all safety ratings and temperature coefficient specifications. These parts differ in lead spacing (10.00mm versus 7.50mm) and should be evaluated for PCB layout compatibility. KEMET parts carry active product status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the Vishay VY2102M29Y5UG63V7 directly replace the Panasonic ECK-ATS102ME?

A: Yes. Both parts share identical capacitance (1000 pF), tolerance (±20%), voltage rating (440VAC), temperature coefficient (Y5U), and safety ratings (X1, Y2). The Vishay part features kinked formed leads and a slightly smaller disc diameter (7.50mm versus 8.00mm), which may require PCB layout verification for lead spacing compatibility.

Q: What is the difference between the three Vishay substitute options?

A: VY2102M29Y5UG63V7, VY2102M29Y5US63V7, and VY2102M29Y5US6TV7 are electrically identical. The differences are packaging format: the first two are bulk packaging, while the third is cut tape format. Selection depends on procurement volume and assembly line requirements.

Q: Can KEMET C901U102MYWDBA7317 or C907U102MYWDBA7317 be used as direct replacements?

A: These KEMET parts are functionally compatible for applications where 400VAC operation is acceptable. They maintain the same capacitance, tolerance, temperature coefficient, and safety ratings as the original part. However, the 40VAC voltage derating must be evaluated against circuit design margins. Lead spacing differs between the two KEMET options (10.00mm versus 7.50mm), requiring PCB layout assessment.

Q: Are all substitute parts RoHS compliant?

A: Yes. All Vishay and KEMET substitute parts listed are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the operating temperature range difference between the original and substitute parts?

A: The Panasonic ECK-ATS102ME operates from -25°C to 125°C. All substitute parts extend the lower temperature limit to -40°C, providing improved performance in cold environment applications.
