Substitute Part Grouping Explanation

Substitution for the EEF-UD0D471LR is determined by strict equivalence in the following 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)
Type: Polymer (exact match required)

Substitute parts may vary in ESR, lifetime rating, operating temperature range, and product status, provided they maintain the core electrical and mechanical specifications above. Parts are grouped by their current product status and compliance certifications.

Engineering Selection Recommendations

For new designs, select from parts with Active product status and ROHS3 compliance. The following Panasonic SP-Cap series parts are recommended as direct substitutes:

EEF-SX0D471ER is the primary equivalent, offering identical ESR (9 mOhm) to the original part with doubled lifetime rating (2000 hours at 105°C) and extended operating temperature range (-55°C to 105°C). This part carries Active status and full ROHS3 compliance.

For applications requiring lower ESR performance, EEF-GX0D471R (3 mOhm ESR) and EEF-SX0D471E4 (4.5 mOhm ESR) are available with Active status. Both provide 2000-hour lifetime ratings and ROHS3 compliance.

For mid-range ESR requirements, EEF-LX0D471R (6 mOhm ESR) and EEF-SX0D471XE (6 mOhm ESR) are suitable alternatives with Active status and equivalent performance characteristics.

Parts marked "Not For New Designs" (EEF-SX0D471R, EEF-SX0D471XR) are available for legacy system support only. The Murata ECASD60D477M006K00 is obsolete and should not be selected for new applications.

Frequently Asked Questions (FAQ)

Q: Can EEF-UD0D471LR be directly replaced with any of these substitute parts?

A: Yes. All listed substitute parts maintain the core specifications: 470 µF capacitance, 2 V voltage rating, ±20% tolerance, 2917 (7343 Metric) package, and surface mount configuration. Physical footprint and electrical characteristics are compatible.

Q: What is the difference between the various Panasonic SP-Cap series (UD, SX, CX, GX, LX)?

A: These represent different product generations and performance tiers within Panasonic's polymer capacitor portfolio. The primary differences are ESR values, lifetime ratings, and product status. All maintain identical capacitance, voltage, tolerance, and package specifications.

Q: Why does EEF-SX0D471ER have a longer lifetime than the original EEF-UD0D471LR?

A: EEF-SX0D471ER belongs to an active product line with improved formulation, delivering 2000 hours at 105°C compared to the original 1000 hours. This represents a design improvement in the polymer capacitor technology.

Q: Is the operating temperature range difference significant?

A: The original part operates from -40°C to 105°C. Most active substitutes extend this to -55°C to 105°C, providing broader environmental compatibility. This is a performance enhancement with no negative impact on existing applications.

Q: Which substitute should I select for high-ripple-current applications?

A: ESR directly affects ripple current handling. EEF-GX0D471R (3 mOhm ESR) supports 10.2 A at 100 kHz, the highest among available options. EEF-SX0D471E4 and EEF-LX0D471R4 support 8.5 A at 100 kHz. Lower ESR values enable higher ripple current capacity.

Q: Are all active substitutes ROHS3 compliant?

A: Yes. All parts with Active product status carry ROHS3 compliance and REACH Unaffected certification, meeting current regulatory requirements for electronics manufacturing.

Q: Can I use ECASD60D477M006K00 from Murata as a substitute?

A: ECASD60D477M006K00 is obsolete and should not be selected for new designs. It is listed for reference only to identify equivalent legacy parts in existing systems.
