Package Type: Radial, Can - Snap-In
Lead Spacing: 0.394" (10.00 mm)
Diameter: 1.378" (35.00 mm)
Mounting Type: Through Hole
Operating Temperature Range: -40°C to 105°C

Acceptable Variations:

Height: Substitute parts may vary in seated height (ranging from 1.063" to 1.457") provided mechanical clearance exists in the application
Lifetime at Temperature: Substitute parts with equal or greater lifetime (3000 Hrs @ 105°C or higher) are acceptable

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height than the original ECO-S2DA102EA?

A: Yes, provided mechanical clearance exists in your application. The original part has a maximum seated height of 1.457" (37.00 mm). Substitute parts range from 1.063" to 1.457" in height. Verify that the selected substitute fits within your PCB layout and enclosure constraints before implementation.

Q: What is the difference between direct equivalents and upgrade options?

A: Direct equivalents match the original 200 V rating and 3000 Hrs @ 105°C lifetime. Upgrade options provide either higher voltage ratings (220 V or 250 V) or extended lifetime (5000 Hrs or 10000 Hrs @ 105°C). Upgrades are backward-compatible with applications designed for the original part but offer enhanced performance margins or reliability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All active substitute parts listed are ROHS3 compliant. The original ECO-S2DA102EA does not specify RoHS status due to its obsolete status. If RoHS compliance is a requirement for your application, select from the active substitute parts provided.

Q: Can I use the 180MXG1000MEFCSN35X25 (180 V) in place of the ECO-S2DA102EA (200 V)?

A: Only if your application operates at voltages not exceeding 180 V. The 180 V part is not suitable for applications designed for 200 V operation. Use this part only when you have confirmed that your circuit voltage will not exceed 180 V under any operating condition, including transient overvoltage events.

Q: What does the ±20% tolerance mean for capacitance?

A: The actual capacitance value will be within ±20% of the nominal 1000 µF rating. This means the capacitance can range from 800 µF to 1200 µF. All substitute parts maintain this same tolerance specification, ensuring compatibility with applications designed for the original part.

Q: Which substitute part offers the best long-term reliability?

A: The LGR2D102MELC35 (Nichicon) provides the longest operational lifetime at 10000 Hrs @ 105°C, compared to 3000 Hrs for most direct equivalents. The B43255A2108M (EPCOS - TDK Electronics) offers an intermediate option with 5000 Hrs @ 105°C. Select based on your application's expected operational life and environmental conditions.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. The LGU2D102MELC (Nichicon) has the highest inventory availability at 273,882 pcs. Most other active substitutes have inventory ranging from 751 to 3,588 pcs. For high-volume production, verify current inventory status with your component supplier.

Q: What is ESR and why does it vary among substitute parts?

A: ESR (Equivalent Series Resistance) affects the capacitor's ability to handle ripple current and heat dissipation. Lower ESR values indicate better performance under AC ripple conditions. The original ECO-S2DA102EA has 216 mOhm @ 120 Hz. The 381LR102M200A022 offers improved ESR at 149 mOhm @ 120 Hz. When ESR is not specified for a substitute part, contact the manufacturer for detailed specifications if ripple current performance is critical to your application.
