ECA-2DM010 Equivalent & Substitute Parts

Part Overview

The ECA-2DM010 is a 1 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This part belongs to the M-A series and is classified as obsolete, with a rated lifetime of 2000 hours at 85°C. Due to its obsolete status, direct replacement with active production equivalents or higher-rated alternatives is necessary for new designs and ongoing procurement.

Substitute Part Grouping Explanation

Substitution for ECA-2DM010 is determined by the following criteria:

Direct Electrical Equivalents (same capacitance, voltage, tolerance, and physical dimensions):

Capacitance: 1 µF (fixed)
Voltage Rating: 200 V (minimum requirement)
Tolerance: ±20% (fixed)
Package: Radial, Can with identical lead spacing and case dimensions
Mounting: Through Hole

Upgrade Substitutes (higher voltage rating with identical physical footprint):

Capacitance: 1 µF (fixed)
Voltage Rating: 250 V, 350 V, or 400 V (higher than original 200 V)
Tolerance: ±20% (fixed)
Package: Radial, Can with identical lead spacing and case dimensions
Mounting: Through Hole

All substitute parts maintain the same physical dimensions (0.248" diameter, 0.480" height, 0.098" lead spacing) to ensure PCB compatibility. Voltage upgrades provide additional design margin without requiring layout changes.

Engineering Selection Recommendations

For Direct Replacement (Same Voltage Rating):

ECA-2DHG010 is the primary active equivalent from Panasonic. It maintains the 200 V rating and 1 µF capacitance while offering improved thermal performance (2000 Hrs @ 105°C versus 85°C) and ROHS3 compliance. The NHG-A series provides enhanced reliability over the obsolete M-A series.

ESMQ201ELL1R0MF11D from Chemi-Con provides an alternative direct equivalent with identical electrical specifications and ROHS3 compliance. This part extends the lower operating temperature to -40°C.

For Voltage Upgrade Substitutes:

ECA-2EM010 and ECA-2EM010I (250 V rating) provide a conservative voltage upgrade while maintaining the same physical footprint and M-A series characteristics.

ECA-2VM010 and ECA-2VM010I (350 V rating) offer increased voltage margin with M-A series thermal performance.

ECA-2GM010 and ECA-2GM010I (400 V rating) deliver maximum voltage headroom within the M-A series.

ECA-2GHG010 (400 V rating) combines maximum voltage rating with enhanced thermal performance (2000 Hrs @ 105°C) and NHG-A series reliability.

ECA-2VHG010 (350 V rating) provides a mid-range voltage upgrade with superior thermal performance.

All Panasonic substitutes are ROHS3 compliant and maintain identical physical dimensions for direct PCB compatibility.

Frequently Asked Questions (FAQ)
