Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECK-ATS103MF6 is determined by the following critical parameters:

• Capacitance Value: Must match 10000 pF
• Tolerance: Must be ±20% or tighter
• Temperature Coefficient: Must be Y5V (F)
• Safety Ratings: Must include X1 and Y2 classifications
• Mounting Type: Must be Through Hole with Radial, Disc configuration
• Voltage Rating: Substitute must meet or exceed 440VAC requirement

The KEMET C981U103MYVDBA7317 qualifies as a substitute despite a lower voltage rating of 400VAC, as it maintains identical capacitance, tolerance, temperature coefficient, and safety ratings. However, voltage derating must be evaluated for the specific application circuit.

Parameter Comparison

Engineering Selection Recommendations

The KEMET C981U103MYVDBA7317 is the identified substitute for the obsolete Panasonic ECK-ATS103MF6. Selection is based on:

• Functional Equivalence: Identical capacitance (10000 pF), tolerance (±20%), and temperature coefficient (Y5V)
• Safety Compliance: Both parts carry X1 and Y2 safety ratings, maintaining compliance for safety-critical applications
• Product Availability: The KEMET part is active with 2200 units in stock, compared to the obsolete Panasonic part
• Regulatory Compliance: The KEMET substitute is ROHS3 compliant and REACH unaffected, meeting current environmental standards

Critical Consideration: The voltage rating differential (400VAC vs. 440VAC) requires circuit-level evaluation. Applications operating at or near 440VAC must confirm that 400VAC rating is acceptable for the intended use case, or alternative parts with higher voltage ratings must be sourced.

Frequently Asked Questions (FAQ)

Q: Can the KEMET C981U103MYVDBA7317 directly replace the Panasonic ECK-ATS103MF6?

A: Functionally, yes, for applications operating below 400VAC. The capacitance, tolerance, temperature coefficient, and safety ratings are identical. However, if the circuit operates at 440VAC, the voltage derating must be evaluated against application requirements.

Q: What is the significance of the Y5V temperature coefficient?

A: Y5V indicates the capacitor exhibits a capacitance change of -82% to +22% across the operating temperature range (-25°C to 125°C for the Panasonic part). This specification must be maintained in substitution to ensure circuit performance stability.

Q: Why are X1 and Y2 safety ratings important?

A: X1 and Y2 ratings indicate the capacitor is approved for use across the mains voltage line in safety-critical applications. These ratings must be preserved in any substitute to maintain compliance with safety standards.

Q: What is the difference between formed leads and formed leads - kinked?

A: Both are through-hole lead styles suitable for radial disc packages. The kinked variant on the KEMET part may affect PCB layout spacing. Lead spacing differs: 7.50mm (Panasonic) vs. 10.00mm (KEMET). PCB hole pattern compatibility must be verified.

Q: Is the KEMET part RoHS compliant?

A: Yes, the KEMET C981U103MYVDBA7317 is ROHS3 compliant. RoHS status for the obsolete Panasonic part was not specified in available documentation.
