Equivalent & Substitute Parts for ECA-2DM101

Part Overview

The ECA-2DM101 is a 100 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This component is rated for 2000 hours at 85°C and is designed for general-purpose applications requiring through-hole mounting. The part is ROHS3 compliant and currently active in production with 752 units in stock.

Substitute parts are identified when electrical parameters (capacitance, voltage rating, tolerance, and operating temperature range) remain compatible with the original design, and mechanical dimensions (lead spacing, case size, and height) allow direct board-level replacement without layout modifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Electrical Compatibility: Capacitance value must be 100 µF. Voltage rating must be equal to or greater than 200 V. Tolerance must be ±20% or tighter. Operating temperature range must encompass or exceed -25°C to 85°C.

Mechanical Compatibility: Lead spacing must be 7.50 mm. Case diameter must be 16.00 mm. Height must not exceed 27.00 mm to ensure board clearance and mounting compatibility.

Functional Compatibility: Mounting type must be through-hole. Package configuration must be radial, can. Polarization must be polar.

Parts are grouped into two categories:

Direct Substitutes: Parts meeting all electrical and mechanical parameters with identical or superior performance characteristics at the same voltage rating (200 V).

Upgrade Substitutes: Parts exceeding the original specifications in voltage rating (250 V) or lifetime rating, providing enhanced reliability margins while maintaining mechanical and electrical compatibility.

Engineering Selection Recommendations

For Active Production Designs:

ECA-2DHG101 (Panasonic) provides direct substitution with extended operating temperature range to 105°C while maintaining identical mechanical dimensions and 200 V rating. This part is recommended for designs requiring thermal margin improvement without component redesign.

ECA-2DM101B (Panasonic) is electrically and mechanically identical to the main part, differing only in packaging format (Cut Tape versus Bulk). Selection depends on procurement and assembly requirements.

ESH107M200AM7AA (KEMET) and ESU107M200AM7AA (KEMET) are compatible substitutes with extended temperature ratings. ESU107M200AM7AA offers 12000-hour lifetime at 105°C, providing enhanced reliability for long-term applications.

UBT2D101MHD8 (Nichicon) is rated for automotive applications with extended temperature range to 125°C and 2000-hour lifetime at that temperature. This part is suitable for high-temperature environments.

For Voltage Margin Enhancement:

250BXC100MEFC16X25 (Rubycon), UCS2E101MHD (Nichicon), and UVK2E101MHD (Nichicon) provide 250 V rating, offering 25% voltage headroom above the original 200 V specification. These parts are mechanically compatible and suitable for designs requiring increased voltage safety margin.

Parts Not Recommended for New Designs:

UVK2D101MHD and UVK2E101MHD carry "Not For New Designs" status and should be used only in legacy system maintenance or repair applications.

Frequently Asked Questions (FAQ)

Q: Can ECA-2DM101 be replaced with a 250 V rated capacitor?

A: Yes. Parts rated for 250 V (250BXC100MEFC16X25, UCS2E101MHD, UVK2E101MHD) are electrically compatible because voltage rating is a maximum specification. A higher-rated capacitor operates safely in a 200 V circuit. Mechanical dimensions must remain compatible.

Q: What is the difference between ECA-2DM101 and ECA-2DM101B?

A: Both parts are electrically and mechanically identical. The difference is packaging: ECA-2DM101 is supplied in Bulk packaging, while ECA-2DM101B is supplied in Cut Tape (CT) format. Selection depends on assembly line requirements and procurement preferences.

Q: Why does UAS2D101MHD6 have a different height (22.00 mm vs 27.00 mm)?

A: UAS2D101MHD6 has a shorter physical height while maintaining the same lead spacing and case diameter. This reduced height is compatible with the original design if board clearance permits. Verify available vertical space before substitution.

Q: Can I use a part rated for 2000 Hrs @ 125°C in place of 2000 Hrs @ 85°C?

A: Yes. UBT2D101MHD8 is rated for 2000 hours at 125°C, which exceeds the original 2000 hours at 85°C specification. Higher temperature ratings indicate superior thermal performance and are compatible with the original application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original ECA-2DM101 specification.

Q: What does "Not For New Designs" mean for UVK2D101MHD and UVK2E101MHD?

A: This status indicates the manufacturer has discontinued these parts for new product development. They remain available for existing system support and repair. For new designs, select from parts marked "Active" status.
