ECK-DNA332ME Equivalent & Substitute Parts

Part Overview

The ECK-DNA332ME is a 3300 pF ceramic capacitor rated for 250VAC with Y5U temperature coefficient, manufactured by Panasonic Electronic Components. This component is classified as obsolete, making substitute parts necessary for ongoing production and maintenance applications. The part is designed for safety-rated applications with X1, Y1 ratings and features radial, disc-type construction suitable for through-hole mounting.

Substitute Part Grouping Explanation

Substitution for the ECK-DNA332ME is determined by the following critical parameters:

Capacitance Value: Must be 3300 pF
Tolerance: Must be ±20%
Safety Ratings: Must maintain X1, Y1 classification
Mounting Configuration: Must be through-hole radial, disc construction
Physical Dimensions: Lead spacing, diameter, and height must match or be compatible with PCB layout
Voltage Rating: Substitute parts must meet or exceed the 250VAC requirement

The substitute parts identified (DE1E3RB332MA4BR01F and DE1E3RB332MJ4BR01F) satisfy all critical substitution criteria. Both are manufactured by Murata Electronics and maintain identical capacitance, tolerance, safety ratings, and physical dimensions. The substitute parts feature enhanced voltage ratings (500VAC) and improved temperature coefficient specifications (E vs. Y5U), providing superior performance margins in the target application.

Engineering Selection Recommendations

Both Murata substitute parts (DE1E3RB332MA4BR01F and DE1E3RB332MJ4BR01F) are functionally equivalent to the obsolete ECK-DNA332ME. Selection between the two Murata options may be based on packaging preference (both listed as Bulk) and internal part number designation, as electrical and mechanical specifications are identical.

The Murata substitutes provide the following advantages over the original part:

Active Product Status: Both substitutes are currently in active production, ensuring long-term availability
Enhanced Compliance: ROHS3 compliance and REACH unaffected status meet current regulatory requirements
Improved Performance Margins: 500VAC rating provides 2x voltage headroom compared to the 250VAC original specification
Extended Temperature Range: Operating range of -40°C ~ 125°C exceeds the original -25°C ~ 85°C specification
Identical Physical Footprint: Direct PCB layout compatibility with no redesign required

Frequently Asked Questions (FAQ)

Q: Can DE1E3RB332MA4BR01F or DE1E3RB332MJ4BR01F be used as direct replacements for ECK-DNA332ME?

A: Yes. Both Murata parts are direct substitutes. They maintain identical capacitance (3300 pF), tolerance (±20%), safety ratings (X1, Y1), and physical dimensions (lead spacing, diameter, height). The parts are pin-compatible and require no PCB modifications.

Q: What is the difference between DE1E3RB332MA4BR01F and DE1E3RB332MJ4BR01F?

A: Both parts are electrically and mechanically identical. The difference lies in internal Murata part number designation (MA vs. MJ suffix). Selection may depend on supplier availability or internal inventory management practices.

Q: Why do the substitute parts have a higher voltage rating (500VAC vs. 250VAC)?

A: The 500VAC rating of the Murata substitutes provides enhanced performance margins and safety headroom in the application. This higher rating does not affect circuit operation at the original 250VAC design specification and is fully compatible with the application requirements.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both Murata substitutes (DE1E3RB332MA4BR01F and DE1E3RB332MJ4BR01F) are ROHS3 compliant, whereas the original ECK-DNA332ME is RoHS non-compliant. This compliance improvement aligns with current manufacturing and regulatory standards.

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

A: The Murata substitutes operate from -40°C to 125°C, which exceeds the original ECK-DNA332ME range of -25°C to 85°C. This extended range provides additional thermal margin for demanding applications.

Q: Are there any mechanical compatibility concerns with the substitute parts?

A: No. The substitute parts maintain identical physical dimensions: 0.512" (13.00mm) diameter, 0.630" (16.00mm) seated height, and 0.394" (10.00mm) lead spacing. Direct PCB mounting compatibility is confirmed.
