EEU-FC1A272B Equivalent & Substitute Parts

Part Overview

The EEU-FC1A272B is a 2700 µF, 10 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 Tape & Box packaging.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required, or when design requirements permit selection from qualified alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FC1A272B is determined by the following criteria:

Primary Substitution Parameters:

• Capacitance: 2700 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Size / Dimension: 0.492" Dia (12.50mm) (exact match required)

Secondary Substitution Parameters (allowable variation):

• Height - Seated (Max): Variation permitted within mechanical envelope constraints
• Lifetime @ Temperature: Equal or greater duration acceptable
• Ripple Current ratings: Equal or greater capacity acceptable
• Impedance: Equal or lower values acceptable
• Product Status: Active preferred; Not For New Designs acceptable for existing designs

Panasonic EEU-FC series parts with identical electrical specifications but different packaging formats (Bulk vs. Tape & Box) are direct substitutes. Nichicon UPA, UPW, UPJ, and UPM series parts meeting all primary parameters are functionally equivalent alternatives.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Designs: EEU-FC1A272 (Panasonic, Bulk packaging) is the primary direct substitute, offering identical electrical specifications and active product status. EEU-FC1A272S (Panasonic) is electrically equivalent but features different mechanical dimensions (lead spacing and height); verify PCB layout compatibility before selection. UPA1A272MHD1TO (Nichicon, Cut Tape) maintains active status and meets all electrical requirements with marginally lower impedance (29 mOhms vs. 30 mOhms).

For Existing Designs: UPW1A272MHD (Nichicon) provides extended lifetime (7000 Hrs @ 105°C) and is acceptable for existing designs despite Not For New Designs status. UPJ1A272MHD and UPM1A272MHD (Nichicon) are functionally equivalent but carry Not For New Designs designation; use only when primary alternatives are unavailable and design is established.

Compliance Considerations: All listed substitutes maintain ROHS3 compliance. EEU-FC1A272B and EEU-FC1A272 carry AEC-Q200 automotive ratings; Nichicon UPM1A272MHD also meets AEC-Q200. For automotive applications requiring AEC-Q200 certification, select from Panasonic FC series or Nichicon UPM series exclusively.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1A272S be used as a direct replacement for EEU-FC1A272B?

A: EEU-FC1A272S is electrically equivalent but has different mechanical dimensions. Lead spacing is 0.295" (7.50mm) versus 0.197" (5.00mm), and height is 0.591" (15.00mm) versus 1.063" (27.00mm). PCB layout must accommodate these differences before substitution.

Q: What is the difference between Tape & Box and Bulk packaging?

A: Tape & Box packaging (EEU-FC1A272B) is supplied on tape in a box, suitable for automated assembly. Bulk packaging (EEU-FC1A272) is supplied loose in a container, typically for manual assembly or lower-volume applications. Electrical specifications are identical.

Q: Are Nichicon UPA, UPW, UPJ, and UPM series parts suitable for automotive applications?

A: Only Nichicon UPM1A272MHD carries AEC-Q200 automotive rating. UPA1A272MHD1TO, UPW1A272MHD, and UPJ1A272MHD are rated for general purpose applications. For automotive designs, use Panasonic FC series or Nichicon UPM series.

Q: Can I use UPW1A272MHD (7000 Hrs @ 105°C) instead of EEU-FC1A272B (5000 Hrs @ 105°C)?

A: Yes. Extended lifetime is acceptable as a substitute parameter. UPW1A272MHD provides greater thermal endurance and is functionally superior for the same electrical requirements. However, it carries Not For New Designs status; use only in established designs.

Q: What does "Not For New Designs" mean?

A: This designation indicates the manufacturer is phasing out the product. While functionally equivalent and available in inventory, these parts should not be selected for new product designs. Use active status parts (EEU-FC1A272, UPA1A272MHD1TO) for new designs.

Q: Are all substitutes compatible with the same PCB footprint?

A: No. Lead spacing and height vary across substitutes. EEU-FC1A272 and UPA1A272MHD1TO share identical lead spacing (0.197" / 5.00mm) and similar heights, making them footprint-compatible. EEU-FC1A272S has different lead spacing (0.295" / 7.50mm) and requires PCB layout verification.

Q: What is impedance, and why does it vary among substitutes?

A: Impedance (ESR-related parameter) affects ripple current handling and thermal performance. Lower impedance is preferable. EEU-FC1A272B and EEU-FC1A272 both have 30 mOhms. UPA1A272MHD1TO has 29 mOhms (slightly better). EEU-FC1A272S has 38 mOhms (higher); verify ripple current requirements before selection.
