UPJ1H271MPD Equivalent & Substitute Parts

Part Overview

The UPJ1H271MPD is a 270 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 5000 hours at 105°C and is classified as not for new designs. Due to its discontinued status and limited availability for new applications, equivalent substitute parts from both Nichicon and alternative manufacturers are available to maintain design continuity and ensure supply chain flexibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Capacitance: Must be 270 µF
Voltage Rating: Must be 50 V or higher
Tolerance: Must be ±20%
Polarization: Must be Polar
Package Type: Must be Radial, Can
Mounting Type: Must be Through Hole
Lead Spacing: Must be 0.197" (5.00 mm)
Operating Temperature Range: Must support -55°C to 105°C
RoHS Compliance: Must be ROHS3 Compliant

All substitute parts listed meet these core electrical and mechanical parameters. Variations in lifetime rating, ripple current specifications, impedance, physical height, and application certifications do not preclude substitution but may affect performance in specific use cases.

Engineering Selection Recommendations

Nichicon UPJ Series (Main Part) The UPJ1H271MPD offers 5000-hour lifetime at 105°C with general-purpose application rating. This part is not recommended for new designs but remains available for legacy system support and maintenance applications.

Nichicon UPM Series (AEC-Q200 Automotive) The UPM1H271MPD provides equivalent electrical performance with AEC-Q200 automotive qualification and lower impedance (65 mOhms). This part is suitable for automotive applications requiring higher reliability standards, though it maintains not-for-new-designs status.

Nichicon UPW Series (Compact Profile) The UPW1H271MPD delivers the same electrical specifications with a reduced height of 0.984" (25.00 mm), making it suitable for space-constrained applications. This part offers the highest current inventory availability (3259 Pcs).

Panasonic EEU-FC Series (Active Production) Both EEU-FC1H271 and EEU-FC1H271B are actively produced Panasonic alternatives with AEC-Q200 automotive certification. These parts feature 3000-hour lifetime ratings and are available in standard (Bulk) and tape & box packaging options. Height variations (0.984" and 1.063") accommodate different PCB layout requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute UPJ1H271MPD with any of the listed alternatives? A: Yes, all listed parts meet the core electrical and mechanical substitution criteria: 270 µF capacitance, 50 V voltage rating, ±20% tolerance, polar radial can package, 5.00 mm lead spacing, and through-hole mounting. Physical height and lifetime ratings differ but do not prevent functional substitution.

Q: What is the difference between Nichicon UPJ, UPM, and UPW series? A: All three Nichicon series share identical electrical ratings (270 µF, 50 V, 5000 Hrs @ 105°C). The UPM series includes AEC-Q200 automotive certification. The UPW series has a compact 0.984" height compared to UPJ (1.299") and UPM (1.319"). Impedance values vary slightly: UPJ at 85 mOhms, UPM at 65 mOhms, and UPW at 82 mOhms.

Q: Why do Panasonic EEU-FC parts have lower lifetime ratings? A: The EEU-FC series is rated for 3000 hours at 105°C, compared to 5000 hours for Nichicon parts. Both ratings meet standard industrial requirements. The Panasonic parts offer active production status and AEC-Q200 automotive qualification, making them suitable for new designs in automotive applications.

Q: What packaging options are available? A: Nichicon UPJ, UPM, and UPW series are supplied in Bulk packaging. Panasonic EEU-FC1H271 is supplied in Bulk packaging, while EEU-FC1H271B is supplied in Tape & Box (TB) packaging for automated assembly processes.

Q: Are all substitute parts RoHS3 compliant? A: Yes, all listed parts are ROHS3 compliant. The UPJ1H271MPD and UPW1H271MPD are REACH Unaffected, while UPM1H271MPD is REACH Affected. All Panasonic EEU-FC parts are REACH Unaffected.

Q: Which substitute offers the best availability? A: The UPW1H271MPD has the highest inventory at 3259 pieces. Among Panasonic alternatives, both EEU-FC variants have comparable availability (944 and 939 pieces respectively).
