EEU-FC1J180 Equivalent & Substitute Parts

Part Overview

The EEU-FC1J180 is an 18 µF, 63 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This part is rated for 1000 hours at 105°C and meets AEC-Q200 automotive qualification standards. The product status is obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the EEU-FC1J180 is determined by the following critical parameters:

Capacitance value: 18 µF (exact match required)
Voltage rating: 63 V (minimum acceptable)
Polarization: Polar (electrolytic type)
Mounting type: Through Hole (radial leads)
Package style: Radial, Can
Operating temperature range: -55°C ~ 105°C (minimum)
AEC-Q200 automotive qualification

Substitute parts must match all electrical specifications and maintain through-hole radial mounting compatibility. Physical dimensions (diameter, height, lead spacing) may vary within acceptable PCB layout tolerances.

Engineering Selection Recommendations

EEU-FC1J180B and EEU-FC1J180H are direct Panasonic equivalents with active product status and ROHS3 compliance. Both maintain identical electrical specifications and AEC-Q200 automotive qualification. Selection between these two depends on lead spacing requirements: EEU-FC1J180B features 0.197" (5.00mm) lead spacing, while EEU-FC1J180H uses 0.098" (2.50mm) lead spacing.

ELXY630ELL180MFB5D from Chemi-Con is an alternative substitute meeting all core electrical and compliance requirements. This part offers extended lifetime (2000 hours at 105°C versus 1000 hours) and lower impedance (1 Ohm versus 1.3 Ohms), providing enhanced performance characteristics. Lead spacing is 0.098" (2.50mm), matching EEU-FC1J180H.

All substitute parts maintain AEC-Q200 automotive qualification and ROHS3 compliance, ensuring suitability for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1J180B and EEU-FC1J180H be used interchangeably with the original EEU-FC1J180?

A: Both parts are electrically equivalent with identical capacitance, voltage rating, tolerance, and lifetime specifications. Physical differences exist in lead spacing and height. PCB layout compatibility must be verified before substitution.

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

A: The Chemi-Con ELXY630ELL180MFB5D provides extended thermal lifetime (2000 hours at 105°C) and lower impedance (1 Ohm). All parts meet AEC-Q200 automotive standards and maintain identical electrical core specifications.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All listed substitutes carry AEC-Q200 qualification and ROHS3 compliance, meeting automotive industry requirements.

Q: What is the significance of lead spacing differences?

A: Lead spacing affects PCB footprint compatibility. EEU-FC1J180B uses 5.00mm spacing, while EEU-FC1J180H and ELXY630ELL180MFB5D use 2.50mm spacing. Verify PCB design specifications before selection.

Q: Can the Chemi-Con part replace the Panasonic part in all applications?

A: The Chemi-Con ELXY630ELL180MFB5D meets all core electrical and compliance requirements. Physical dimensions differ slightly; verify PCB layout compatibility and lead spacing requirements.
