Engineering Selection Recommendations

For new designs, select from parts with Active product status. The EEF-GX0D331R offers the lowest ESR at 3mOhm with extended lifetime (2000 Hrs @ 105°C) and widened operating temperature range (-55°C ~ 105°C). The EEF-SX0D331E4 and EEF-LX0D331R4 provide balanced ESR performance at 4.5mOhm with high inventory availability.

Parts marked "Not For New Designs" (EEF-SX0D331R, EEF-SX0D331XR) are suitable for legacy system maintenance only. The Murata ECASD60D337M007K00 is obsolete and should not be selected for new applications.

All active Panasonic substitutes carry ROHS3 compliance and REACH Unaffected status. The EEF-UE0D331XR and ECASD60D337M007K00 share identical operating temperature ranges (-40°C ~ 105°C) and 1000-hour lifetime ratings, making them functionally equivalent for legacy replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can I use EEF-GX0D331R as a direct replacement for EEF-UE0D331XR?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (2 V), tolerance (±20%), and package (2917 Metric). The EEF-GX0D331R offers superior ESR performance (3mOhm vs 10mOhm) and extended lifetime (2000 Hrs vs 1000 Hrs @ 105°C).

Q: What is the difference between EEF-SX0D331E4 and EEF-LX0D331R4?

A: Both parts have identical electrical specifications (330 µF, 2 V, 4.5mOhm ESR, 2000 Hrs @ 105°C). The difference is in physical height: EEF-SX0D331E4 is 2.00mm seated height, while EEF-LX0D331R4 is 2.10mm. Select based on PCB layout constraints.

Q: Why is the operating temperature range wider on substitute parts?

A: Active Panasonic substitutes (SP-Cap CX, GX, LX, SX series) support -55°C ~ 105°C, compared to the obsolete UE series at -40°C ~ 105°C. This expanded range does not affect compatibility for applications within the original -40°C ~ 105°C specification.

Q: Are all substitute parts RoHS compliant?

A: All active Panasonic substitutes are ROHS3 compliant. The obsolete EEF-UE0D331XR and Murata ECASD60D337M007K00 do not carry RoHS certification in the provided data.

Q: Which substitute has the best ripple current performance?

A: EEF-GX0D331R supports 10.2 A @ 100 kHz, the highest among all listed parts. EEF-LX0D331R and EEF-SX0D331XE support 7.5 A @ 100 kHz. Select based on application ripple current requirements.
