ECO-S2GA331DA Equivalent & Substitute Parts

Part Overview

The ECO-S2GA331DA is a 330 µF, 400 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the TS-HA series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring 3000 hours of operational life at 105°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing system support and component procurement.

Engineering Selection Recommendations

All listed substitute parts are active production components with ROHS3 compliance, providing long-term availability and regulatory alignment. Selection among substitutes should be based on:

Height Constraint Consideration: The original ECO-S2GA331DA has a maximum seated height of 2.047" (52.00mm). Substitute parts with reduced heights (ranging from 1.260" to 1.850") are mechanically compatible with applications designed for the original part, as they occupy less vertical space. Applications with strict height limitations should prioritize parts with the smallest height ratings.

Lifetime Rating: Parts designated with 5000 Hrs @ 105°C (Rubycon VXG and VXH series) provide extended operational life compared to the original 3000 Hrs specification. These are direct upgrades for applications requiring enhanced reliability.

Manufacturer Availability: Cornell Dubilier 381LR and 381LX series, Rubycon HXG/MXG/MXK/VXG/VXH series, and EPCOS B43254 series all maintain active production status with substantial inventory levels, ensuring consistent supply chain access.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height than the original ECO-S2GA331DA?

A: Yes. The original part has a maximum seated height of 2.047" (52.00mm). All listed substitutes have heights ranging from 1.260" to 1.850", which are mechanically compatible. Verify that your PCB layout and mechanical enclosure accommodate the substitute part's height before installation.

Q: What is the difference between 3000 Hrs and 5000 Hrs lifetime ratings?

A: Both ratings specify operational life at 105°C. The 3000 Hrs rating is equivalent to the original part's specification. The 5000 Hrs rating (Rubycon VXG and VXH series) represents extended operational life and is a direct upgrade for applications requiring higher reliability margins.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active production substitutes listed are ROHS3 compliant. The original ECO-S2GA331DA does not specify RoHS status due to its obsolete status.

Q: Do substitute parts have the same lead spacing and diameter as the original?

A: Yes. All substitute parts maintain the same lead spacing of 0.394" (10.00mm) and diameter of 1.181" (30.00mm) as the original ECO-S2GA331DA, ensuring direct PCB footprint compatibility.

Q: Which substitute offers the best availability?

A: Rubycon 400HXG330MEFC30X35 and 400MXG330MEFCSN30X35 have the highest inventory levels (273,782 and 656,750 units respectively), providing optimal supply chain security.

Q: Can I substitute a part with higher voltage rating than 400 V?

A: The substitution list is limited to 400 V rated parts. Higher voltage ratings are not included as they represent different electrical specifications outside the scope of direct equivalency for this application category.
