EEU-FC1J271 Equivalent & Substitute Parts

Part Overview

The EEU-FC1J271 is a 270 µF, 63 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 standards. The part is currently active in production. Equivalent and substitute parts may be required due to inventory availability, design phase transitions, or specific application requirements where alternative manufacturers' components meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FC1J271 is determined by the following critical parameters:

Electrical Match: Capacitance (270 µF), voltage rating (63 V), and tolerance (±20%) must be identical
Thermal Performance: Lifetime rating at 105°C must meet or exceed 5000 hours
Environmental Compliance: RoHS3 compliance required
Physical Compatibility: Package type (radial, can), mounting type (through hole), lead spacing (7.50mm), and form factor dimensions must accommodate PCB layout constraints
Polarization: Polar configuration required

The substitute parts listed below meet these core criteria while originating from different manufacturers (Nichicon and Chemi-Con). Variations in ripple current ratings, impedance, and product status are noted but do not disqualify substitution when electrical and mechanical parameters align.

Engineering Selection Recommendations

Direct Substitutes (Identical Form Factor)

UPW1J271MHD and EEU-FC1J271 share identical lead spacing (7.50mm), diameter (16.00mm), and height (15.00mm). UPW1J271MHD offers extended lifetime (8000 hours at 105°C) but carries "Not For New Designs" status. This part is suitable for legacy system maintenance or field replacement where the original specification is maintained.

Form Factor Variants (Reduced Footprint)

ELXY630ELL271MK25S and UPM1J271MHD feature smaller physical dimensions (12.50mm diameter, 5.00mm lead spacing, 26.50mm and 27.00mm height respectively). These parts are electrically equivalent but require PCB layout verification due to different mounting hole spacing and increased height. Both maintain AEC-Q200 compliance. ELXY630ELL271MK25S is active in production; UPM1J271MHD is marked "Not For New Designs."

Compliance Considerations

All substitute parts meet ROHS3 compliance. For automotive applications requiring AEC-Q200 certification, ELXY630ELL271MK25S and UPM1J271MHD are qualified. UPW1J271MHD does not carry AEC-Q200 rating and should be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can UPW1J271MHD replace EEU-FC1J271 in a new design?

A: UPW1J271MHD meets all electrical and mechanical specifications for direct substitution. However, it carries "Not For New Designs" status. For new designs, ELXY630ELL271MK25S is recommended as it is active in production and maintains AEC-Q200 automotive qualification.

Q: What is the impact of different lead spacing on PCB compatibility?

A: EEU-FC1J271 and UPW1J271MHD use 7.50mm lead spacing. ELXY630ELL271MK25S and UPM1J271MHD use 5.00mm lead spacing. PCB mounting holes must match the lead spacing of the selected component. Designs using 7.50mm hole spacing cannot accommodate 5.00mm lead spacing without PCB modification.

Q: Are the smaller form factor parts (ELXY630ELL271MK25S, UPM1J271MHD) suitable for space-constrained applications?

A: Yes, electrically. However, these parts have greater height (26.50mm and 27.00mm respectively) compared to the original (15.00mm). Height clearance must be verified against PCB assembly constraints and enclosure design before selection.

Q: Which substitute part is recommended for automotive applications?

A: ELXY630ELL271MK25S is the preferred substitute for automotive applications. It is active in production, maintains AEC-Q200 certification, and meets all electrical specifications of the EEU-FC1J271.

Q: What is the significance of "Not For New Designs" status?

A: Parts marked "Not For New Designs" (UPW1J271MHD, UPM1J271MHD) are suitable for field replacement, legacy system support, and maintenance applications. They should not be selected for new product development unless no other qualified alternatives exist.
