EEU-FC1C271B Equivalent & Substitute Parts

Part Overview

The EEU-FC1C271B is a 270 µF, 16 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the FC series. This radial, through-hole component is rated for 2000 hours at 105°C and meets AEC-Q200 automotive qualification standards. The part is currently active and available in Tape & Box packaging with 889 units in stock.

Equivalent and substitute parts are identified when design requirements allow for variations in lead spacing, case diameter, height, ripple current handling, or component lifetime ratings while maintaining the core electrical specifications of 270 µF capacitance at 16 V with ±20% tolerance.

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the core electrical parameters: 270 µF capacitance, 16 V voltage rating, and ±20% tolerance. All identified substitutes maintain these specifications and operate across the -55°C to 105°C temperature range.

Mechanical compatibility is evaluated based on lead spacing and physical dimensions. Parts with identical lead spacing (0.197" / 5.00 mm) and case diameter (0.315" / 8.00 mm) are direct mechanical substitutes. Parts with different lead spacing (0.138" / 4.60 mm) or larger case diameters (0.394" / 10.00 mm) require PCB layout verification before substitution.

Lifetime ratings vary across substitutes, ranging from 2000 hours to 5000 hours at 105°C. Selection depends on application reliability requirements. Ripple current and impedance specifications differ by manufacturer and series, affecting performance in high-frequency or high-current applications.

Compliance certifications (AEC-Q200, RoHS3, REACH status) are documented for each part to support automotive and regulated applications.

Engineering Selection Recommendations

Direct Mechanical Substitutes (Identical Lead Spacing and Case Diameter)

EEU-FC1C271B can be directly substituted with ELXY160ELL271MJC5S and UPJ1C271MPD6 when PCB layout permits the use of parts with identical 0.197" (5.00 mm) lead spacing and 0.315" to 0.394" case diameters. ELXY160ELL271MJC5S offers extended lifetime (5000 hours at 105°C) and is currently active. UPJ1C271MPD6 provides equivalent electrical performance but carries a "Not For New Designs" status.

Compact Footprint Alternatives (Reduced Lead Spacing)

EEU-FC1C271, UPJ1C271MPD, and UPM1C271MPD feature 0.138" (4.60 mm) lead spacing with 0.315" case diameter, enabling use in space-constrained layouts. These parts maintain electrical equivalence but require PCB redesign. EEU-FC1C271 remains active; Nichicon parts are designated "Not For New Designs."

Extended Lifetime Options

ELXY160ELL271MJC5S and UPM1C271MPD6 provide 5000-hour lifetime ratings at 105°C, compared to the 2000-hour rating of EEU-FC1C271B. These parts support applications requiring enhanced reliability margins.

Compliance Considerations

EEU-FC1C271B, EEU-FC1C271, ELXY160ELL271MH12D, ELXY160ELL271MJC5S, UPM1C271MPD, and UPM1C271MPD6 meet AEC-Q200 automotive qualification. UPJ1C271MPD and UPJ1C271MPD6 do not carry AEC-Q200 certification. All parts are RoHS3 compliant. UPM series parts are REACH Affected; all others are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1C271 be used as a direct replacement for EEU-FC1C271B?

A: EEU-FC1C271 matches the electrical specifications and case diameter but uses 0.138" (4.60 mm) lead spacing instead of 0.197" (5.00 mm). Direct substitution requires PCB layout modification. Both parts are from the same Panasonic FC series and maintain 2000-hour lifetime at 105°C.

Q: What is the difference between Nichicon UPJ and UPM series parts?

A: Both series provide 270 µF at 16 V with ±20% tolerance. UPM series carries AEC-Q200 automotive certification and lower impedance (140 mOhms vs. 220 mOhms), making it suitable for automotive applications. Both series are designated "Not For New Designs." UPM is REACH Affected; UPJ is REACH Unaffected.

Q: Why does ELXY160ELL271MJC5S have a larger case diameter?

A: The ELXY160ELL271MJC5S uses a 0.394" (10.00 mm) case diameter to accommodate its 5000-hour lifetime rating at 105°C. This larger package provides extended operational life compared to the 0.315" (8.00 mm) diameter of EEU-FC1C271B. PCB layout verification is required before substitution.

Q: Are all substitute parts currently in production?

A: EEU-FC1C271B, EEU-FC1C271, ELXY160ELL271MH12D, and ELXY160ELL271MJC5S are active products. UPJ1C271MPD, UPJ1C271MPD6, UPM1C271MPD, and UPM1C271MPD6 are designated "Not For New Designs," indicating they are available for existing designs but not recommended for new development.

Q: How do ripple current ratings affect part selection?

A: Ripple current capacity varies across substitutes, ranging from 222.5 mA to 470 mA at 120 Hz. Selection depends on circuit requirements. EEU-FC1C271B handles 360.8 mA at 120 Hz. Parts with higher ripple current ratings provide additional margin in high-current applications.

Q: What packaging options are available?

A: EEU-FC1C271B is supplied in Tape & Box packaging. All substitute parts are available in Bulk packaging. Packaging selection affects procurement and assembly processes but does not alter electrical or mechanical performance.
