ECA-1CM472B Equivalent & Substitute Parts

Part Overview

The ECA-1CM472B is a 4700 µF, 16 V aluminum electrolytic capacitor in radial configuration manufactured by Panasonic Electronic Components. This component is rated for 2000 hours at 85°C and is classified as Active product status. Equivalent and substitute parts are identified based on matching capacitance, voltage rating, tolerance, package type, and mechanical dimensions. Alternative parts may be required due to inventory constraints, application-specific performance requirements, or design optimization needs.

Substitute Part Grouping Explanation

Substitution relationships are established based on the following criteria:

Direct Equivalents match all critical parameters: 4700 µF capacitance, 16 V voltage rating, ±20% tolerance, radial through-hole package, identical lead spacing (7.50 mm), and identical physical dimensions (16.00 mm diameter, 27.00 mm height maximum).

Upgrade Substitutes maintain the same capacitance, voltage, tolerance, package, and dimensions but offer enhanced performance characteristics such as extended lifetime ratings or expanded operating temperature ranges.

Parametric Equivalents satisfy all mechanical and electrical compatibility requirements while originating from different manufacturers.

Parts that differ in voltage rating (25 V instead of 16 V) or lifetime specifications are classified as upgrades and are suitable only when circuit design permits higher voltage ratings.

Engineering Selection Recommendations

For Active Product Status Applications:

EEU-FR1C472B (Panasonic) is the preferred direct substitute. It maintains identical electrical and mechanical specifications while offering extended lifetime (10000 hours at 105°C) and expanded operating temperature range (-40°C to 105°C). Both parts are ROHS3 compliant and REACH unaffected.

ECA-1CHG472 (Panasonic) provides an alternative with expanded operating temperature range (-55°C to 105°C) and is suitable for applications requiring lower temperature operation.

860010380025 (Würth Elektronik) is a direct equivalent from an alternative manufacturer. Physical dimensions are nearly identical with maximum height of 26.50 mm versus 27.00 mm. Both are ROHS3 compliant.

UPA1C472MHD1TN (Nichicon) offers enhanced performance with 5000-hour lifetime at 105°C and expanded operating temperature range (-55°C to 105°C). This part is ROHS3 compliant but REACH affected.

For Legacy or Existing Designs:

UFW1C472MHD1TN, UKW1C472MHD1TN, UVR1C472MHD, and UVR1C472MHD1TN (Nichicon) are marked as "Not For New Designs" and should be used only for replacement or maintenance of existing assemblies.

For Higher Voltage Requirements:

EEU-HD1E472B (Panasonic, 25 V) and UVK1E472MHD1TN (Nichicon, 25 V) are suitable only when circuit design permits 25 V rated components. Both maintain identical physical dimensions and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can EEU-FR1C472B replace ECA-1CM472B directly?

A: Yes. Both parts share identical capacitance (4700 µF), voltage rating (16 V), tolerance (±20%), lead spacing (7.50 mm), and physical dimensions (16.00 mm diameter, 27.00 mm height). EEU-FR1C472B is electrically and mechanically compatible and offers superior lifetime characteristics.

Q: What is the difference between 16 V and 25 V rated parts?

A: Voltage rating indicates the maximum continuous voltage the capacitor can withstand. A 25 V rated capacitor (EEU-HD1E472B or UVK1E472MHD1TN) can be used in circuits designed for 16 V operation, but not vice versa. Use 25 V parts only when circuit design explicitly permits higher voltage ratings.

Q: Why are some parts marked "Not For New Designs"?

A: Parts with "Not For New Designs" status (UFW1C472MHD1TN, UKW1C472MHD1TN, UVR1C472MHD, UVR1C472MHD1TN) are legacy components. They remain available for replacement and maintenance of existing products but should not be selected for new circuit designs. Active status parts are recommended for new applications.

Q: Are all substitute parts ROHS3 compliant?

A: All listed parts are ROHS3 compliant. However, UPA1C472MHD1TN is REACH affected, while all other parts are REACH unaffected. Verify REACH compliance requirements for your specific application.

Q: What is the significance of lifetime ratings (2000 Hrs @ 85°C vs. 10000 Hrs @ 105°C)?

A: Lifetime rating indicates the expected operational duration under specified temperature conditions. EEU-FR1C472B (10000 hours at 105°C) provides longer service life under elevated temperature conditions compared to ECA-1CM472B (2000 hours at 85°C). Select based on application temperature profile and required service life.

Q: Can I use Nichicon parts as direct replacements?

A: Nichicon parts (UPA1C472MHD1TN, UFW1C472MHD1TN, UKW1C472MHD1TN, UVR1C472MHD, UVR1C472MHD1TN) are mechanically and electrically compatible with ECA-1CM472B. All share identical lead spacing and physical dimensions. Verify product status and compliance requirements for your application before selection.

Q: Is the 0.5 mm height difference between 860010380025 and ECA-1CM472B significant?

A: The Würth Elektronik part 860010380025 has a maximum height of 26.50 mm compared to 27.00 mm for ECA-1CM472B. This 0.5 mm difference is within typical PCB layout tolerances and does not affect mechanical compatibility in standard through-hole applications.
