Equivalent & Substitute Parts for ECA-2DM4R7BJ

Part Overview

The Panasonic ECA-2DM4R7BJ is a 4.7 µF, 200 V aluminum electrolytic capacitor in radial, can package with a rated lifetime of 2000 hours at 85°C. This component is classified as Active product status and is suitable for general-purpose applications requiring polar capacitive filtering and energy storage.

Substitute parts are necessary when the original component becomes unavailable, when design requirements demand higher voltage ratings or extended operating temperature ranges, or when alternative manufacturer sourcing is required for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECA-2DM4R7BJ is determined by the following criteria:

Mandatory Parameters (Must Match):

• Capacitance: 4.7 µF
• Tolerance: ±20%
• Lead Spacing: 0.138" (4.60mm)
• Package / Case: Radial, Can
• Mounting Type: Through Hole
• Polarization: Polar

Allowable Variation Parameters:

• Voltage Rating: Equal to or greater than 200 V
• Operating Temperature Range: Equal to or greater than the original range
• Lifetime @ Temperature: Equal to or greater than 2000 Hrs @ 85°C
• Physical Dimensions: Minor variations acceptable if lead spacing and package type remain constant
• Manufacturer: Alternative manufacturers permitted

Substitute parts are grouped into two categories: direct equivalents (same voltage rating) and upgraded equivalents (higher voltage ratings with compatible mechanical and electrical characteristics).

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Designs:

ECA-2EM4R7 (Panasonic, 250 V) is the preferred direct substitute within the Panasonic M-A series. It maintains manufacturer continuity, Active product status, and provides a 50 V voltage margin above the original specification while preserving identical mechanical and thermal characteristics.

UVC2G4R7MPD1TD (Nichicon, 400 V) is the recommended upgrade substitute for designs requiring extended operating temperature range (-40°C to 105°C) and higher voltage margin. This part maintains Active product status and supports thermal operation up to 105°C, compared to the original 85°C maximum.

For Legacy or Constrained Designs:

UVR2D4R7MPD1TD and UVR2E4R7MPD1TD are functionally compatible substitutes but carry "Not For New Designs" product status. These parts are suitable only for replacement in existing applications where supply continuity is required. UVK2V4R7MPD1TD similarly carries "Not For New Designs" status and should not be selected for new circuit designs.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance. UVC2G4R7MPD1TD carries REACH Affected status, whereas the original part and all other substitutes are REACH Unaffected. This distinction is relevant for applications subject to REACH regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can ECA-2EM4R7 be used as a direct replacement for ECA-2DM4R7BJ?

A: Yes. ECA-2EM4R7 is a direct mechanical and electrical substitute with identical capacitance (4.7 µF), tolerance (±20%), lead spacing (4.60mm), and package type (Radial, Can). The 250 V rating provides additional voltage margin above the original 200 V specification. Both parts maintain Active product status and ROHS3 compliance.

Q: What is the difference between the Panasonic and Nichicon substitute options?

A: Panasonic ECA-2EM4R7 maintains the same manufacturer as the original part and identical thermal characteristics (2000 Hrs @ 85°C, -25°C to 85°C operating range). Nichicon substitutes (UVR2D4R7MPD1TD, UVR2E4R7MPD1TD, UVK2V4R7MPD1TD, UVC2G4R7MPD1TD) offer extended operating temperature range (-40°C to 85°C or -40°C to 105°C) but carry "Not For New Designs" status except for UVC2G4R7MPD1TD, which is Active.

Q: Why do some substitute parts have "Not For New Designs" status?

A: "Not For New Designs" status indicates that the manufacturer has discontinued active development and production planning for these parts. They remain available for replacement in existing applications but should not be selected for new circuit designs. For new designs, select ECA-2EM4R7 or UVC2G4R7MPD1TD, both carrying Active status.

Q: Is the 0.512" (13.00mm) height of Nichicon parts compatible with the original 0.492" (12.50mm) height?

A: The Nichicon substitutes are mechanically compatible in through-hole applications with 0.138" (4.60mm) lead spacing. The 0.020" (0.50mm) height difference does not affect electrical function or standard PCB layout. Verify clearance in your specific application if height-constrained space exists above the component.

Q: Can UVC2G4R7MPD1TD be used in applications requiring only 200 V operation?

A: Yes. UVC2G4R7MPD1TD is rated for 400 V operation, which exceeds the 200 V requirement of the original circuit. Higher voltage rating does not degrade performance in lower-voltage applications. This part is suitable for designs requiring extended temperature operation up to 105°C.

Q: What is the significance of REACH Affected status for UVC2G4R7MPD1TD?

A: REACH Affected status indicates that the part contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory requirements. This distinction is relevant only for applications subject to REACH compliance obligations. For applications without REACH requirements, this status does not affect component selection.
