Engineering Selection Recommendations

For General Purpose Applications: UPJ1E271MPD6 provides extended lifetime (5000 hours at 105°C) while maintaining Nichicon series continuity and Not For New Designs status. This option is suitable for legacy system maintenance where design refresh is not planned.

For Automotive Applications with AEC-Q200 Compliance: UPM1E271MPD6 offers automotive-grade qualification with superior impedance characteristics (110 mOhms) and extended lifetime. This part is appropriate for automotive circuit designs requiring formal compliance documentation.

For Active Product Status and Immediate Availability: EEU-FC1E271 and EEU-FC1E271B from Panasonic Electronic Components are classified as Active products with AEC-Q200 automotive ratings. These parts provide the lowest impedance (90 mOhms) and are suitable for new designs or system upgrades. EEU-FC1E271B is available in Cut Tape packaging for automated assembly processes.

Physical Fit Consideration: The UPJ1E271MPD features a smaller footprint (8.00mm diameter, 21.00mm height) compared to all substitute parts (10.00mm diameter, 12.50–17.00mm height). PCB layout verification is required before substitution to confirm lead spacing and mounting hole compatibility.

Frequently Asked Questions (FAQ)

Q: Can UPJ1E271MPD be directly replaced with UPJ1E271MPD6?

A: Yes. Both parts are Nichicon UPJ series components with identical electrical specifications (270 µF, 25 V, ±20%). UPJ1E271MPD6 provides extended lifetime (5000 hours versus 3000 hours at 105°C). Lead spacing differs (5.00mm versus 4.60mm), requiring PCB layout verification.

Q: What is the primary difference between Nichicon and Panasonic substitutes?

A: Nichicon UPJ and UPM series parts maintain the original manufacturer lineage. Panasonic EEU-FC series parts offer Active product status, lower impedance (90 mOhms), and AEC-Q200 automotive qualification. Panasonic parts feature reduced physical height, improving space efficiency in compact designs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and meet environmental regulatory requirements.

Q: Which substitute part has the lowest impedance?

A: EEU-FC1E271 and EEU-FC1E271B both feature 90 mOhms impedance, the lowest among all listed parts. This characteristic reduces voltage ripple and improves transient response in power supply applications.

Q: Can EEU-FC1E271B be used in automated assembly?

A: Yes. EEU-FC1E271B is packaged in Cut Tape (CT) format, suitable for pick-and-place automated assembly equipment. EEU-FC1E271 is available in Bulk packaging for manual assembly or tape-and-reel conversion.

Q: Is UPM1E271MPD6 suitable for automotive applications?

A: Yes. UPM1E271MPD6 carries AEC-Q200 automotive qualification and is rated for automotive applications. This part is appropriate for automotive circuit designs requiring formal compliance documentation.

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

A: Lead spacing affects PCB hole positioning and mounting compatibility. UPJ1E271MPD uses 4.60mm spacing; all substitute parts use 5.00mm spacing. PCB redesign or adapter solutions may be required for direct mechanical substitution.
