Panasonic EEF-UE0D561R Equivalent & Substitute Parts

Part Overview

The Panasonic EEF-UE0D561R is a 560 µF, 2 V aluminum polymer surface mount capacitor in the 2917 (7343 Metric) package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The EEF-UE series has been superseded by active production alternatives within Panasonic's SP-Cap polymer capacitor portfolio, which maintain the same electrical specifications while offering improved performance characteristics and extended component lifecycle.

Substitute Part Grouping Explanation

Substitution of the EEF-UE0D561R is determined by strict equivalence in the following parameters:

Capacitance: 560 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: Aluminum Polymer (exact match required)

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in ESR, lifetime rating, operating temperature range, and ripple current capacity represent performance improvements in active production alternatives and do not preclude substitution compatibility.

Engineering Selection Recommendations

All listed substitute parts are direct functional equivalents to the EEF-UE0D561R based on core electrical and mechanical parameters. Selection among active alternatives should be based on the following criteria:

EEF-CX0D561R: Suitable for applications where ESR tolerance of 15 mOhm is acceptable and extended lifetime (2000 Hrs @ 105°C) is beneficial. ROHS3 compliant.

EEF-LX0D561R: Recommended for designs requiring lower ESR (6 mOhm) and higher ripple current capability (7.5 A @ 100 kHz). Extended operating temperature range (-55°C ~ 105°C). ROHS3 compliant.

EEF-LX0D561R4: Optimal for applications demanding minimum ESR (4.5 mOhm) and maximum ripple current capacity (8.5 A @ 100 kHz). Highest inventory availability (8098 Pcs). ROHS3 compliant.

EEF-SX0D561E4: Equivalent ESR and ripple current performance to EEF-LX0D561R4 (4.5 mOhm, 8.5 A @ 100 kHz) with reduced seated height (2.00 mm vs. 2.10 mm). Largest inventory stock (17440 Pcs). ROHS3 compliant.

All substitute parts carry ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for modern electronics manufacturing.

Frequently Asked Questions (FAQ)

Q: Can the EEF-UE0D561R be directly replaced with any of these substitute parts?

A: Yes. All listed parts maintain identical capacitance (560 µF), voltage rating (2 V), tolerance (±20%), package (2917 / 7343 Metric), and mounting type (Surface Mount). They are direct functional equivalents.

Q: What is the difference between the substitute parts?

A: The primary differences are ESR (ranging from 4.5 mOhm to 15 mOhm), lifetime rating (all substitutes offer 2000 Hrs @ 105°C vs. 1000 Hrs for the main part), ripple current capacity, and seated height. These represent performance enhancements in active production series.

Q: Does lower ESR always mean better performance?

A: Lower ESR reduces heat generation and improves transient response in high-frequency applications. However, selection should be based on specific circuit requirements. All listed parts are electrically compatible.

Q: Are there any height restrictions I should consider?

A: The EEF-UE0D561R has a seated height of 4.20 mm. Substitute parts range from 1.90 mm to 2.10 mm, offering significant height reduction. Verify PCB layout clearance before selection.

Q: Which substitute part has the best availability?

A: EEF-SX0D561E4 has the highest inventory (17440 Pcs), followed by EEF-LX0D561R4 (8098 Pcs).

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards.
