Equivalent & Substitute Parts for EEF-UE0D561LR

Part Overview

The EEF-UE0D561LR is a 560 µF, 2 V aluminum polymer capacitor manufactured by Panasonic Electronic Components in the 2917 (7343 Metric) surface mount package. This part is classified as obsolete, making identification of suitable alternatives essential for ongoing design support and production continuity. The SP-Cap UE series has been superseded by newer polymer capacitor generations with improved performance characteristics and extended operational lifetimes.

Substitute Part Grouping Explanation

Substitution eligibility for the EEF-UE0D561LR is determined by strict equivalence in the following parameters:

Capacitance Value: 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, and operating temperature range are permitted within the scope of direct substitution, as these represent performance enhancements or extended operational capabilities rather than functional incompatibilities.

Engineering Selection Recommendations

All three substitute parts—EEF-SX0D561E4, EEF-LX0D561R, and EEF-LX0D561R4—are active products from Panasonic Electronic Components and are suitable direct replacements for the obsolete EEF-UE0D561LR based on electrical and mechanical parameter equivalence.

EEF-SX0D561E4 offers the lowest ESR at 4.5 mOhm and the highest ripple current capability at 8.5 A @ 100 kHz, combined with the most compact height of 2.00 mm. This part is ROHS3 compliant and REACH unaffected.

EEF-LX0D561R provides a mid-range ESR of 6 mOhm with a ripple current rating of 7.5 A @ 100 kHz and a height of 2.10 mm. This part is ROHS3 compliant and REACH unaffected.

EEF-LX0D561R4 matches the performance of EEF-SX0D561E4 with 4.5 mOhm ESR and 8.5 A ripple current capability, with a height of 2.10 mm. This part is ROHS3 compliant and REACH unaffected.

All substitute parts feature extended lifetime ratings of 2000 Hrs @ 105°C compared to the original 1000 Hrs @ 105°C, and all support an expanded operating temperature range of -55°C ~ 105°C.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0D561E4, EEF-LX0D561R, or EEF-LX0D561R4 be used as direct replacements for EEF-UE0D561LR?

A: Yes. All three parts maintain identical capacitance (560 µF), voltage rating (2 V), tolerance (±20%), package (2917 / 7343 Metric), and mounting type (surface mount). They are functionally equivalent for circuit applications designed for the original part.

Q: What are the key differences between the substitute parts?

A: The primary differences are ESR and ripple current capability. EEF-SX0D561E4 and EEF-LX0D561R4 both feature 4.5 mOhm ESR and 8.5 A ripple current, while EEF-LX0D561R has 6 mOhm ESR and 7.5 A ripple current. Physical height also varies: EEF-SX0D561E4 is 2.00 mm, while both LX variants are 2.10 mm.

Q: Does the reduced height of EEF-SX0D561E4 affect PCB layout compatibility?

A: No. The reduced height of 2.00 mm (compared to the original 4.20 mm) is a design improvement that provides greater PCB layout flexibility. The footprint remains identical at 7.30 mm × 4.30 mm, ensuring direct compatibility with existing land patterns.

Q: Are all substitute parts RoHS and REACH compliant?

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

Q: Which substitute part should be selected for applications requiring maximum ripple current handling?

A: Both EEF-SX0D561E4 and EEF-LX0D561R4 support 8.5 A ripple current @ 100 kHz, the highest rating among the available substitutes.
