EEF-SD0D331ER Equivalent & Substitute Parts

Part Overview

The EEF-SD0D331ER is a 330 µF, 2 V aluminum polymer capacitor in 2917 (7343 Metric) surface mount package manufactured by Panasonic Electronic Components. This part operates across -40°C to 105°C with a rated lifetime of 1000 hours at 105°C and is classified as Obsolete. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following parameters: capacitance (330 µF), voltage rating (2 V), tolerance (±20%), package type (2917 / 7343 Metric), and mounting configuration (Surface Mount). All substitute parts maintain identical footprint and land pattern compatibility.

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalents (Panasonic SP-Cap Series): Parts with identical electrical specifications and active product status, suitable for direct replacement in new designs.

Parametric Equivalents: Parts from alternative manufacturers meeting the same electrical and mechanical specifications, with consideration for product lifecycle status and compliance certifications.

Engineering Selection Recommendations

For new designs, select from Panasonic SP-Cap series parts with Active product status: EEF-SX0D331XE, EEF-GX0D331R, EEF-LX0D331R, EEF-LX0D331R4, or EEF-SX0D331E4. All are ROHS3 compliant and offer extended lifetime ratings of 2000 hours at 105°C compared to the obsolete EEF-SD0D331ER.

For existing production requiring direct replacement of EEF-SD0D331ER, EEF-SX0D331ER and EEF-LX0D331R provide equivalent electrical performance with improved specifications and active availability.

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

The Murata ECASD60D337M007K00 provides parametric equivalence with identical ESR and ripple current specifications but carries obsolete status; it is not recommended for new designs.

Frequently Asked Questions (FAQ)

Q: Can EEF-SD0D331ER be directly replaced with any of the listed substitutes?

A: Yes, all listed parts maintain identical capacitance (330 µF), voltage rating (2 V), tolerance (±20%), and package footprint (2917 / 7343 Metric). Physical mounting compatibility is guaranteed. However, electrical performance characteristics such as ESR and ripple current handling vary across series.

Q: What is the primary difference between substitute part series?

A: Substitute parts differ in ESR (ranging from 3 to 15 mOhm), ripple current capacity (4.6 to 10.2 A @ 100 kHz), and lifetime ratings. EEF-GX0D331R offers the lowest ESR (3 mOhm) and highest ripple current (10.2 A), while EEF-CX0D331R has the highest ESR (15 mOhm) but maintains 2000-hour lifetime.

Q: Are all substitute parts RoHS3 compliant?

A: All Panasonic SP-Cap series substitutes (EEF-SX, EEF-CX, EEF-GX, EEF-LX) are ROHS3 compliant. The original EEF-SD0D331ER and Murata ECASD60D337M007K00 do not carry RoHS3 certification.

Q: What is the height difference between the original part and substitutes?

A: The original EEF-SD0D331ER has a seated height of 2.80 mm. Most substitutes are lower: EEF-SX series at 2.00 mm, EEF-CX at 1.90 mm, and EEF-LX at 2.10 mm. This reduction in height may provide design benefits in space-constrained applications while maintaining identical footprint.

Q: Which substitute offers the best performance for high-ripple-current applications?

A: EEF-GX0D331R provides the highest ripple current capacity at 10.2 A @ 100 kHz with the lowest ESR at 3 mOhm, making it optimal for applications requiring superior high-frequency performance.

Q: Can parts marked "Not For New Designs" be used in production?

A: Parts with "Not For New Designs" status (EEF-SX0D331R, EEF-SX0D331XR) are restricted to legacy system support and maintenance only. They should not be selected for new product development.
