EEU-FC1C272 Equivalent & Substitute Parts

Part Overview

The EEU-FC1C272 is a 2700 µF, 16 V aluminum electrolytic capacitor in radial configuration manufactured by Panasonic Electronic Components. This capacitor is rated for 5000 hours at 105°C and meets AEC-Q200 automotive qualification standards. The part is actively produced and widely used in automotive applications requiring reliable energy storage and filtering.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements shift between automotive and general-purpose applications. The substitute parts listed maintain electrical equivalence while offering variations in physical dimensions, packaging formats, and thermal ratings.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict electrical parameter matching: capacitance value (2700 µF), voltage rating (16 V), tolerance (±20%), polarization (polar), and mounting type (through hole). All listed substitutes meet these core electrical requirements.

Substitutes are grouped into two categories based on provided data:

Panasonic FC Series Variants: EEU-FC1C272B and EEU-FC1C272L maintain identical electrical specifications but differ in packaging format (Cut Tape vs. Bulk) and physical dimensions. Both retain AEC-Q200 automotive qualification.

Nichicon UPW/UPJ/UPM Series: These parts provide electrical equivalence with variations in thermal lifetime ratings (5000–8000 hours at 105°C), physical footprints, and product status designations. UPM1C272MHD retains AEC-Q200 automotive qualification; UPW and UPJ series are designated "Not For New Designs."

Engineering Selection Recommendations

For Active Production Designs: EEU-FC1C272B and EEU-FC1C272L are preferred substitutes. Both are Panasonic FC series parts with Active product status and AEC-Q200 automotive qualification. EEU-FC1C272B provides a direct footprint match with identical lead spacing and diameter; EEU-FC1C272L offers a compact footprint with reduced lead spacing (5.00 mm vs. 7.50 mm) and lower impedance (25 mOhms vs. 29 mOhms).

For Automotive Applications Requiring AEC-Q200: UPM1C272MHD is the only Nichicon substitute that maintains AEC-Q200 qualification. However, it carries "Not For New Designs" status and features a different physical footprint with tighter lead spacing (5.00 mm) and extended height (37.50 mm).

For General-Purpose Applications: UPW1C272MHD and UPW1C272MHD6 offer extended thermal lifetime (7000–8000 hours at 105°C) but lack AEC-Q200 certification and carry "Not For New Designs" designation. UPW1C272MHD6 maintains the original footprint dimensions. UPJ1C272MHD is not recommended due to absence of AEC-Q200 qualification and "Not For New Designs" status.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1C272L be used as a direct replacement for EEU-FC1C272?

A: Electrical substitution is valid; however, physical footprint differs. EEU-FC1C272L uses 5.00 mm lead spacing versus 7.50 mm on the original part. PCB layout modification is required. Both parts maintain AEC-Q200 automotive qualification and identical electrical ratings.

Q: What is the difference between EEU-FC1C272B and EEU-FC1C272?

A: The primary difference is packaging format: EEU-FC1C272B is supplied in Cut Tape (CT) format, while EEU-FC1C272 is supplied in Bulk. Electrical specifications are identical. Physical height differs slightly (0.866" vs. 0.787"), which may affect PCB clearance in space-constrained designs.

Q: Why are Nichicon UPW and UPJ series marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued these series for new product development. While electrically equivalent, these parts should be used only for legacy system maintenance or when inventory of active-status alternatives is unavailable.

Q: Is UPM1C272MHD suitable for automotive applications?

A: UPM1C272MHD maintains AEC-Q200 automotive qualification and is electrically equivalent. However, it carries "Not For New Designs" status. For new automotive designs, EEU-FC1C272, EEU-FC1C272B, or EEU-FC1C272L are recommended.

Q: What does impedance variation (25–31 mOhms) mean for circuit performance?

A: Lower impedance (25 mOhms) provides superior high-frequency ripple current handling and reduced voltage ripple. Substitutes with 25 mOhms impedance (EEU-FC1C272L, UPM1C272MHD, UPW series) offer improved performance in switching power supplies and high-frequency filtering applications compared to the 29 mOhms baseline.

Q: Can UPW1C272MHD6 replace EEU-FC1C272 in automotive circuits?

A: Electrical and physical footprint compatibility exists; however, UPW1C272MHD6 lacks AEC-Q200 automotive qualification and carries "Not For New Designs" status. Use is restricted to non-automotive applications or legacy system support.
