EEU-FC1C682 Equivalent & Substitute Parts

Part Overview

The EEU-FC1C682 is a 6800 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The capacitor is rated for automotive use with AEC-Q200 compliance and operates across a temperature range of -55°C to 105°C with a 5000-hour lifetime at maximum temperature.

Substitute Part Grouping Explanation

Substitution for the EEU-FC1C682 is determined by strict equivalence in the following parameters:

Capacitance: 6800 µF (exact match required)
Voltage Rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.295" (7.50 mm) (exact match required)
Polarization: Polar (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in lifetime rating, ripple current specifications, impedance, and physical dimensions (diameter and height) are secondary considerations that do not prevent functional substitution when the primary parameters align.

Engineering Selection Recommendations

For applications requiring the EEU-FC1C682, the ELXZ160ELL682ML40S (Chemi-Con) is the primary substitute. This part maintains all core electrical and mechanical parameters while offering active product status and extended lifetime (8000 hours at 105°C versus 5000 hours). Both parts carry AEC-Q200 automotive certification and ROHS3 compliance.

The UPJ1C682MHD and UPW1C682MHD (Nichicon) are functionally equivalent substitutes with identical capacitance, voltage, tolerance, and package specifications. Both are marked as "Not For New Designs," indicating limited availability for future production. The UPW1C682MHD offers extended lifetime (8000 hours) comparable to the Chemi-Con alternative.

All substitute parts are through-hole mounted with identical lead spacing (7.50 mm), ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the ELXZ160ELL682ML40S replace the EEU-FC1C682 directly on the PCB?

A: Yes. Both parts share identical lead spacing (0.295" / 7.50 mm), capacitance (6800 µF), voltage rating (16 V), and through-hole mounting type. No PCB layout changes are required.

Q: What is the difference between the Chemi-Con and Nichicon substitutes?

A: The ELXZ160ELL682ML40S (Chemi-Con) has active product status and 8000-hour lifetime at 105°C. The UPJ1C682MHD and UPW1C682MHD (Nichicon) are marked "Not For New Designs." The UPW1C682MHD offers 8000-hour lifetime, while UPJ1C682MHD provides 5000-hour lifetime.

Q: Are all substitutes automotive-rated?

A: The EEU-FC1C682 and ELXZ160ELL682ML40S carry AEC-Q200 automotive certification. The Nichicon parts (UPJ1C682MHD and UPW1C682MHD) are rated for general purpose applications without automotive certification listed.

Q: Do the substitute parts have different physical dimensions?

A: The ELXZ160ELL682ML40S has a maximum seated height of 1.634" (41.50 mm) compared to 1.575" (40.00 mm) for the original. The Nichicon parts have larger diameters (0.709" / 18.00 mm versus 0.630" / 16.00 mm) and different heights. Verify clearance in your application before substitution.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts, including the original EEU-FC1C682 and all substitutes, are ROHS3 compliant.
