EEU-FC1C272B Equivalent & Substitute Parts

Part Overview

The EEU-FC1C272B is a 2700 µF, 16 V aluminum electrolytic capacitor in radial configuration manufactured by Panasonic Electronic Components. This component is rated for 5000 hours at 105°C and meets AEC-Q200 automotive specifications. The part is currently active and available in Cut Tape packaging.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required, or when design revisions call for components with enhanced performance characteristics such as extended lifetime ratings or improved electrical properties.

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FC1C272B is determined by strict equivalence across the following critical parameters:

Capacitance value: 2700 µF (exact match required)
Voltage rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting type: Through Hole (exact match required)
Package type: Radial, Can (exact match required)
Operating temperature range: -55°C ~ 105°C (exact match required)

Substitute parts are grouped into three categories:

Direct Substitutes (Packaging Variant): EEU-FC1C272 differs only in packaging format (Bulk vs. Cut Tape) and seated height (0.787" vs. 0.866"), maintaining identical electrical specifications and lifetime rating.

Similar Substitutes (Dimensional Variant): EEU-FC1C272L maintains all electrical parameters but features different lead spacing (0.197" vs. 0.295"), diameter (0.492" vs. 0.630"), and height (1.181" vs. 0.866"), with marginally improved ripple current and impedance characteristics.

Cross-Manufacturer Substitutes (Nichicon Series): UPM1C272MHD, UPJ1C272MHD, UPW1C272MHD, and UPW1C272MHD6 are Nichicon equivalents with identical electrical ratings. UPW1C272MHD6 offers extended lifetime (8000 Hrs vs. 5000 Hrs). Dimensional variations exist across these parts.

Engineering Selection Recommendations

For Active Production: EEU-FC1C272B remains the primary choice as an active product with AEC-Q200 automotive certification. EEU-FC1C272 serves as the direct substitute when Bulk packaging is acceptable, with identical electrical performance and only minor height variation (0.787" vs. 0.866").

For Dimensional Constraints: EEU-FC1C272L is suitable when reduced footprint is required. The smaller diameter (0.492" vs. 0.630") and tighter lead spacing (0.197" vs. 0.295") accommodate compact PCB layouts, though increased height (1.181" vs. 0.866") must be verified against available vertical clearance.

For Extended Lifetime Applications: UPW1C272MHD6 provides 8000-hour lifetime at 105°C compared to the standard 5000-hour rating, with identical dimensional and electrical characteristics to EEU-FC1C272. However, this part carries "Not For New Designs" status and should be used only in legacy system maintenance or when extended operational life is contractually mandated.

Cross-Manufacturer Alternatives: Nichicon UPM1C272MHD, UPJ1C272MHD, and UPW1C272MHD are electrically equivalent but carry "Not For New Designs" designation. These parts feature different physical dimensions and should be selected only when primary Panasonic options are unavailable and design revision is feasible. UPM1C272MHD maintains AEC-Q200 certification; UPJ1C272MHD and UPW1C272MHD do not.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1C272 replace EEU-FC1C272B directly on the PCB?

A: Yes, with one consideration. EEU-FC1C272 has a seated height of 0.787" compared to EEU-FC1C272B's 0.866". Verify that the reduced height does not create clearance issues with adjacent components or enclosure constraints. All electrical parameters and lead spacing are identical.

Q: What is the difference between EEU-FC1C272L and EEU-FC1C272B?

A: EEU-FC1C272L has a smaller physical footprint (0.492" diameter vs. 0.630", 0.197" lead spacing vs. 0.295") and taller profile (1.181" vs. 0.866"). Electrical ratings are identical. This part is suitable for space-constrained designs but requires PCB layout modification.

Q: Why do Nichicon parts show "Not For New Designs" status?

A: This designation indicates that the manufacturer has discontinued these series for new applications. While electrically equivalent, they should be used only for replacement or legacy system support. For new designs, Panasonic FC series parts are recommended.

Q: Is UPW1C272MHD6 compatible with automotive applications?

A: UPW1C272MHD6 does not carry AEC-Q200 certification, unlike EEU-FC1C272B and UPM1C272MHD. For automotive applications requiring AEC-Q200 compliance, use EEU-FC1C272B or UPM1C272MHD.

Q: Can I use UPW1C272MHD6 for its extended 8000-hour lifetime?

A: UPW1C272MHD6 offers 8000-hour lifetime at 105°C versus the standard 5000-hour rating. However, it carries "Not For New Designs" status. Use this part only when extended operational life is a contractual requirement and design revision is acceptable. Verify that the 0.787" height matches your PCB layout.

Q: What are the ripple current differences, and do they matter?

A: Ripple current ratings vary slightly across substitutes (1.874 A to 2.0 A @ 120 Hz). These differences are within normal manufacturing tolerance and do not affect substitution eligibility. Select based on your circuit's actual ripple current requirements; all listed parts exceed typical application demands.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed parts are ROHS3 compliant. Environmental compliance is consistent across the entire substitute group.
