EEU-FC1C560B Equivalent & Substitute Parts

Part Overview

The EEU-FC1C560B is a 56 µF, 16 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the FC series. This radial, through-hole component is rated for 1000 hours at 105°C and meets AEC-Q200 automotive qualification standards. The part is currently active in production with cut tape packaging available.

Equivalent and substitute parts are identified when electrical specifications (capacitance, voltage rating, tolerance, ripple current, impedance) and mechanical parameters (lead spacing, case size, mounting type) align within acceptable tolerances for the application. This reference provides direct substitution options based on matching core parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FC1C560B is determined by the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 56 µF
• Voltage Rating: 16 V
• Tolerance: ±20%
• Operating Temperature Range: -55°C to 105°C
• Polarization: Polar

Mechanical Parameters (Must Match):

• Case Diameter: 0.197" (5.00 mm)
• Mounting Type: Through Hole, Radial
• Package Type: Radial, Can

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected

The following parts meet these substitution criteria and are listed as equivalent options:

1. EEU-FC1C560 (Panasonic) – Identical electrical specifications, bulk packaging, reduced lead spacing (0.079" vs. 0.197"), slightly shorter height (0.472" vs. 0.571")
2. UPM1C560MDD (Nichicon) – Identical electrical specifications, extended lifetime (2000 hrs @ 105°C), reduced lead spacing, lower impedance (650 mOhms vs. 800 mOhms), obsolete status
3. UPW1C560MDD (Nichicon) – Identical electrical specifications, extended lifetime (2000 hrs @ 105°C), reduced lead spacing, lowest impedance (600 mOhms), obsolete status, general purpose rating

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Recommended for New Designs): EEU-FC1C560 is the preferred substitute when the EEU-FC1C560B is unavailable. Both parts are manufactured by Panasonic, share identical electrical specifications, and maintain AEC-Q200 automotive qualification. The EEU-FC1C560 is currently active in production. The reduced lead spacing (0.079" vs. 0.197") and lower profile height (0.472" vs. 0.571") may require PCB layout verification for existing designs.

Secondary Substitutes (Obsolete Status): UPM1C560MDD and UPW1C560MDD are obsolete Nichicon parts that meet all electrical and mechanical substitution criteria. These parts offer extended lifetime ratings (2000 hours vs. 1000 hours at 105°C) and lower impedance characteristics. UPM1C560MDD maintains AEC-Q200 automotive qualification; UPW1C560MDD is rated for general purpose applications only. Availability is limited to existing inventory.

Lead Spacing Consideration: The EEU-FC1C560B features 0.197" (5.00 mm) lead spacing, while all substitute parts feature 0.079" (2.00 mm) lead spacing. PCB footprint compatibility must be confirmed before substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1C560 be used as a direct replacement for EEU-FC1C560B? A: Yes, electrically and mechanically. Both parts share identical capacitance (56 µF), voltage rating (16 V), tolerance (±20%), operating temperature range (-55°C to 105°C), case diameter (5.00 mm), and mounting type (through-hole radial). Both are AEC-Q200 qualified and ROHS3 compliant. The primary difference is lead spacing: EEU-FC1C560B uses 0.197" spacing while EEU-FC1C560 uses 0.079" spacing. PCB layout compatibility must be verified.

Q: What is the difference between the Panasonic FC series and Nichicon UPM/UPW series? A: All three series meet the core electrical specifications for this substitution. The Nichicon UPM and UPW series offer extended lifetime ratings (2000 hours at 105°C vs. 1000 hours), resulting in lower impedance values. UPM1C560MDD maintains automotive qualification (AEC-Q200); UPW1C560MDD is general purpose rated. Both Nichicon parts are obsolete.

Q: Are the Nichicon UPM1C560MDD and UPW1C560MDD suitable for automotive applications? A: UPM1C560MDD is AEC-Q200 qualified and suitable for automotive use. UPW1C560MDD is rated for general purpose applications and does not carry automotive qualification. For automotive designs, UPM1C560MDD is the appropriate choice among the Nichicon options.

Q: What does the reduced lead spacing on substitute parts mean for my design? A: Lead spacing refers to the distance between the two leads on the capacitor. EEU-FC1C560B has 0.197" (5.00 mm) spacing, while EEU-FC1C560, UPM1C560MDD, and UPW1C560MDD all have 0.079" (2.00 mm) spacing. If your PCB footprint is designed for 5.00 mm spacing, the 2.00 mm lead spacing parts will not fit without PCB modification or adapter solutions.

Q: Why are UPM1C560MDD and UPW1C560MDD listed as obsolete? A: Product status reflects manufacturer availability. Obsolete parts may still be available through existing inventory channels but are no longer in active production. For new designs, active parts (EEU-FC1C560B or EEU-FC1C560) are recommended.

Q: How do impedance differences affect substitution? A: Impedance values (EEU-FC1C560B: 800 mOhms; UPM1C560MDD: 650 mOhms; UPW1C560MDD: 600 mOhms) indicate the capacitor's resistance to AC current flow. Lower impedance generally provides better high-frequency performance. For applications sensitive to impedance characteristics, circuit simulation or testing may be required to confirm performance equivalence.
