EEU-FC1H271 Equivalent & Substitute Parts

Part Overview

The EEU-FC1H271 is a 270 µF, 50 V aluminum electrolytic capacitor in radial can package manufactured by Panasonic Electronic Components. This component is rated for 3000 hours at 105°C and meets AEC-Q200 automotive standards. The part is currently active in production. Equivalent and substitute parts are necessary when the primary part is unavailable, when design requirements demand extended operational lifetime, or when alternative manufacturer sourcing is required for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FC1H271 is determined by the following criteria:

Core Electrical Parameters (Must Match):

• Capacitance: 270 µF
• Voltage Rating: 50 V
• Tolerance: ±20%
• Polarization: Polar

Core Mechanical Parameters (Must Match):

• Package Type: Radial, Can
• Lead Spacing: 0.197" (5.00 mm)
• Diameter: 0.394" (10.00 mm)
• Mounting Type: Through Hole

Allowable Variations:

• Height: Variations permitted within PCB layout constraints
• Lifetime @ 105°C: Extended lifetime acceptable
• Ripple Current: Variations acceptable if application requirements are met
• Impedance: Variations acceptable within application tolerance
• Manufacturer: Different manufacturers acceptable if electrical and mechanical parameters align

The three substitute parts listed below meet all core electrical and mechanical parameters and are therefore functionally equivalent for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs: The EEU-FC1H271 remains the primary selection as it carries Active product status and AEC-Q200 automotive qualification. This part is recommended for new automotive applications requiring established supply chain continuity.

For Extended Lifetime Requirements: UPW1H271MPD, UPJ1H271MPD, and UPM1H271MPD all provide 5000-hour lifetime at 105°C, compared to 3000 hours for the EEU-FC1H271. These parts are suitable for replacement in existing designs where extended operational life is required. Note that all three Nichicon alternatives carry "Not For New Designs" status.

For Automotive Applications with AEC-Q200 Requirement: Both EEU-FC1H271 and UPM1H271MPD meet AEC-Q200 certification. UPM1H271MPD provides extended lifetime and lower impedance (65 mOhms versus 82 mOhms) but is marked "Not For New Designs." For new automotive designs, EEU-FC1H271 is the appropriate selection.

For PCB Layout Constraints: UPW1H271MPD maintains the same height as the EEU-FC1H271 (0.984" / 25.00 mm), making it the preferred substitute when vertical clearance is limited. UPJ1H271MPD and UPM1H271MPD are taller (33.00 mm and 34.60 mm respectively) and require PCB layout verification before substitution.

For General Purpose Applications: All three Nichicon parts are suitable for general purpose applications where automotive qualification is not required. Selection should be based on available inventory, height constraints, and lifetime requirements.

Frequently Asked Questions (FAQ)

Q: Can UPW1H271MPD, UPJ1H271MPD, or UPM1H271MPD be used as direct replacements for EEU-FC1H271?

A: Yes, all three parts meet the core electrical parameters (270 µF, 50 V, ±20% tolerance) and mechanical parameters (radial can package, 5.00 mm lead spacing, 10.00 mm diameter, through-hole mounting). However, height differences must be verified against PCB layout. UPW1H271MPD matches the original height; UPJ1H271MPD and UPM1H271MPD are taller and require layout confirmation.

Q: What is the difference between the three Nichicon substitutes?

A: All three share identical electrical ratings (270 µF, 50 V, ±20% tolerance, 5000-hour lifetime at 105°C). Differences include: UPW1H271MPD matches the original height (25.00 mm); UPJ1H271MPD and UPM1H271MPD are taller (33.00 mm and 34.60 mm). UPM1H271MPD has lower impedance (65 mOhms) and carries AEC-Q200 automotive certification. UPJ1H271MPD has slightly higher impedance (85 mOhms) and lacks automotive certification.

Q: Why are the Nichicon parts marked "Not For New Designs"?

A: Product status reflects manufacturer recommendations for design phase selection. These parts remain functionally equivalent and suitable for replacement in existing designs or where supply constraints require alternative sourcing. For new designs, EEU-FC1H271 is the recommended primary selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all four parts (EEU-FC1H271, UPW1H271MPD, UPJ1H271MPD, and UPM1H271MPD) are ROHS3 compliant.

Q: Which substitute part should I use if my PCB has limited vertical clearance?

A: UPW1H271MPD is the only substitute that maintains the original height of 0.984" (25.00 mm). UPJ1H271MPD and UPM1H271MPD are approximately 8 mm taller and require PCB layout verification before use.

Q: Can I use UPM1H271MPD in automotive applications?

A: Yes, UPM1H271MPD carries AEC-Q200 automotive certification and is suitable for automotive applications. However, it is marked "Not For New Designs," so it is appropriate for replacement in existing automotive designs rather than new development.
