ECA-2DM010B Equivalent & Substitute Parts

Part Overview

The ECA-2DM010B 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. Due to its obsolete status, equivalent and substitute parts with improved specifications or active product status are necessary for new designs and ongoing production requirements.

Engineering Selection Recommendations

For Direct Replacement (Same Voltage, Active Status): ECA-2DHG010B is the primary direct substitute. It maintains the 200 V rating and identical mechanical footprint while offering extended operating temperature range (-25°C ~ 105°C) and improved thermal performance (2000 Hrs @ 105°C). Product status is Active with RoHS3 compliance.

For Voltage Margin Enhancement: ECA-2EM010B, ECA-2VHG010B, ECA-2VHG010B, ECA-2GHG010B, and ECA-2GM010B provide higher voltage ratings (250 V, 350 V, 400 V respectively) while maintaining identical mechanical dimensions and capacitance. These are suitable for applications requiring increased voltage safety margin. All are Active status with RoHS3 compliance.

For Extended Temperature Performance: ECA-2DHG010B, ECA-2EHG010B, ECA-2GHG010B, and ECA-2VHG010B offer extended operating temperature range to 105°C, compared to the original 85°C maximum. These NHG-A series parts support higher thermal environments.

For Cross-Manufacturer Compatibility: MAL214231085E3 (Vishay Beyschlag/Draloric/BC Components) provides 350 V rating with extended lifetime (2500 Hrs @ 105°C) and wider operating temperature range (-40°C ~ 105°C). Height variance is 0.492" (12.50mm) versus 0.480" (12.20mm), acceptable for most through-hole applications. RoHS3 compliant and Active status.

SK010M200ST (Cornell Dubilier Electronics) maintains 200 V rating and identical capacitance. Lead spacing differs at 0.098" (2.50mm) versus 0.197" (5.00mm), and height is 0.512" (13.00mm). This part requires PCB layout verification before selection. Active status with RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can ECA-2DHG010B directly replace ECA-2DM010B without circuit modification?

A: Yes. ECA-2DHG010B maintains identical capacitance (1 µF), tolerance (±20%), voltage rating (200 V), and mechanical footprint (lead spacing 0.197", height 0.480"). The extended operating temperature range and improved lifetime are backward compatible. No circuit modification is required.

Q: Why would I select a higher voltage-rated part like ECA-2GM010B (400 V) instead of ECA-2DHG010B (200 V)?

A: Higher voltage ratings provide increased safety margin in applications subject to voltage transients or overshoot conditions. ECA-2GM010B offers 400 V rating with identical mechanical compatibility. Selection depends on circuit voltage stress analysis and reliability requirements.

Q: What is the difference between the M-A and NHG-A series?

A: M-A series parts (ECA-2DM010B, ECA-2EM010B, ECA-2GM010B, ECA-2VM010B) operate to 85°C maximum with 2000 Hrs lifetime at that temperature. NHG-A series parts (ECA-2DHG010B, ECA-2EHG010B, ECA-2GHG010B, ECA-2VHG010B) operate to 105°C maximum with 2000 Hrs lifetime at that temperature. Both series maintain identical mechanical dimensions and electrical characteristics at rated voltage.

Q: Is SK010M200ST compatible with the original ECA-2DM010B footprint?

A: Partial compatibility exists. Capacitance, voltage, and tolerance match. However, lead spacing differs (0.098" versus 0.197") and height is 0.512" versus 0.480". PCB layout verification is required before selection. This part is suitable only if the PCB can accommodate the different lead spacing.

Q: Can MAL214231085E3 be used in high-temperature applications?

A: Yes. MAL214231085E3 supports operating temperature range of -40°C ~ 105°C with 2500 Hrs lifetime at 105°C, exceeding the original part's -25°C ~ 85°C range and 2000 Hrs lifetime. This part is suitable for extended thermal environments.

Q: Are all substitute parts RoHS3 compliant?

A: All Panasonic substitute parts (ECA-2DHG010B, ECA-2EHG010B, ECA-2EM010B, ECA-2GHG010B, ECA-2GM010B, ECA-2VHG010B, ECA-2VM010B) are RoHS3 compliant. MAL214231085E3 and SK010M200ST are also RoHS3 compliant. The original ECA-2DM010B does not specify RoHS status.

Q: What packaging options are available for these substitutes?

A: Panasonic M-A series parts are supplied in Cut Tape (CT) packaging. Panasonic NHG-A series parts are supplied in Tape & Box (TB) packaging. MAL214231085E3 is supplied in Tape & Box (TB). SK010M200ST packaging is not specified. Verify packaging requirements for your procurement and assembly process.
