Engineering Selection Recommendations

All listed substitute parts are active products from established manufacturers with full RoHS3 compliance or RoHS compliance status. The EET-HC2G331EA is obsolete; therefore, any of the listed substitutes are suitable for new designs and production continuity.

For applications requiring extended operational life at elevated temperature, the Rubycon 400VXG330MEFC35X30 and Chemi-Con ELXS401VSN331MA25S offer 5000-hour lifetime ratings at 105°C, compared to the original 2000-hour specification.

For applications with space constraints, the EKMS401VSN331MA25S, ELXS401VSN331MA25S, and B43640D9337M000 provide reduced seated heights (1.083" to 1.063") while maintaining all core electrical parameters.

The EPCOS B43640D9337M000 extends the lower operating temperature limit to -40°C, suitable for applications requiring enhanced cold-temperature performance.

Frequently Asked Questions (FAQ)

Q: Can I substitute the EET-HC2G331EA with any of the listed parts?

A: Yes. All listed parts meet the core electrical and mechanical specifications: 330 µF capacitance, 400 V voltage rating, ±20% tolerance, radial snap-in package, 10.00 mm lead spacing, 35.00 mm diameter, and through-hole mounting. Physical fit and electrical performance are equivalent.

Q: What is the difference between parts with different lifetime ratings?

A: Lifetime at temperature indicates the expected operational duration at 105°C before capacitance degradation reaches specified limits. The original EET-HC2G331EA is rated for 2000 hours. Substitutes with 3000-hour or 5000-hour ratings provide extended service life under identical thermal conditions. Selection depends on application requirements.

Q: Do height variations affect compatibility?

A: Height variations exist among substitutes (ranging from 1.063" to 1.260" seated height). Verify available board space before selection. Parts with reduced height may be preferred for space-constrained designs, provided the application does not require the exact original height.

Q: Are all substitutes RoHS compliant?

A: Yes. All active substitute parts carry RoHS3 compliance or RoHS compliance certification. The original EET-HC2G331EA is obsolete and does not carry current compliance status.

Q: Which substitute offers the best performance match to the original part?

A: The 381LR331M400A022 (Cornell Dubilier Electronics) and EKMM401VSN331MA30S (Chemi-Con) provide the closest dimensional and electrical match, with identical seated height (1.260") and equivalent operating parameters.
