EEF-SX0D471R Equivalent & Substitute Parts

Part Overview

The EEF-SX0D471R is a 470 µF, 2 V aluminum polymer capacitor in 2917 (7343 Metric) surface mount package manufactured by Panasonic Electronic Components. This part operates across -55°C to 105°C with a rated lifetime of 2000 hours at 105°C and is compliant with ROHS3 and REACH standards.

The EEF-SX0D471R carries a "Not For New Designs" product status, indicating it is no longer recommended for new circuit development. Equivalent and substitute parts are available from Panasonic's active product lines, offering improved electrical characteristics or enhanced availability while maintaining core functional parameters.

Substitute Part Grouping Explanation

Substitution for the EEF-SX0D471R is determined by strict adherence to the following core parameters:

Capacitance: 470 µF (exact match required)
Voltage Rating: 2 V (exact match required)
Tolerance: ±20% (exact match required)
Package / Case: 2917 (7343 Metric) (exact match required)
Mounting Type: Surface Mount (exact match required)
Operating Temperature Range: -55°C to 105°C (minimum requirement)
Lifetime @ Temperature: 2000 Hrs @ 105°C (minimum requirement)
Type: Aluminum - Polymer (exact match required)

Parts meeting these criteria are listed as direct substitutes. Secondary parameters such as ESR (Equivalent Series Resistance) and ripple current capability may vary between substitute parts, reflecting different series within Panasonic's product portfolio or alternative manufacturers. These variations do not affect functional substitutability when core parameters are matched.

Engineering Selection Recommendations

For new designs, select from Panasonic's active product status parts: EEF-CX0D471R, EEF-GX0D471R, EEF-LX0D471R, EEF-LX0D471R4, EEF-SX0D471E4, EEF-SX0D471XE, or EEF-SX0D471ER. All maintain ROHS3 compliance and REACH unaffected status.

EEF-SX0D471ER provides parametric equivalence to the original EEF-SX0D471R with identical ESR (9 mOhm) and height (2.00mm) while offering active product status and higher inventory availability (22109 Pcs).

EEF-SX0D471E4 and EEF-SX0D471XE are active alternatives within the SP-Cap SX series, offering reduced ESR values (4.5 mOhm and 6 mOhm respectively) with superior inventory levels (34487 Pcs and 62480 Pcs).

The Murata ECASD60D477M006K00 carries obsolete status and reduced lifetime rating (1000 Hrs @ 105°C versus 2000 Hrs), making it unsuitable for new applications.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0D471E4 replace EEF-SX0D471R directly?

A: Yes. Both parts share identical capacitance (470 µF), voltage rating (2 V), tolerance (±20%), package (2917), and lifetime (2000 Hrs @ 105°C). The EEF-SX0D471E4 features lower ESR (4.5 mOhm versus 9 mOhm), which represents improved electrical performance within the same functional specification.

Q: What is the difference between EEF-LX0D471R and EEF-LX0D471R4?

A: Both are SP-Cap LX series parts with identical core parameters. The primary difference is ESR: EEF-LX0D471R has 6 mOhm while EEF-LX0D471R4 has 4.5 mOhm. The EEF-LX0D471R4 also exhibits higher ripple current capability (8.5 A @ 100 kHz versus 7.5 A @ 100 kHz). Height differs slightly: 2.10mm for both variants.

Q: Why is the Murata ECASD60D477M006K00 not recommended?

A: The Murata part carries obsolete product status and specifies only 1000 hours lifetime at 105°C, compared to 2000 hours for Panasonic equivalents. Additionally, its maximum height (2.80mm) exceeds all Panasonic alternatives, potentially creating PCB layout conflicts.

Q: Are all substitute parts ROHS3 compliant?

A: All Panasonic substitute parts listed are ROHS3 compliant and REACH unaffected. The Murata ECASD60D477M006K00 is also ROHS3 compliant but carries obsolete status.

Q: What is the significance of ESR variation among substitutes?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. Lower ESR values (3 mOhm to 6 mOhm) provide superior high-frequency ripple current capability. The original EEF-SX0D471R at 9 mOhm is matched by the active EEF-SX0D471ER. Selection should consider circuit ripple current requirements and thermal constraints.

Q: Can parts with different heights be used interchangeably on the same PCB?

A: Height differences range from 1.90mm (EEF-CX0D471R) to 2.80mm (Murata ECASD60D477M006K00). PCB land patterns and component placement clearances must accommodate the selected part's maximum height. Verify mechanical fit before substitution.
