UPJ1V271MPD Equivalent & Substitute Parts

Part Overview

The UPJ1V271MPD is a 270 µF, 35 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This part is classified as "Not For New Designs," indicating it has reached end-of-life status. Finding equivalent or substitute parts is necessary for maintenance, repair, and legacy system support where original components are no longer readily available or when design flexibility permits component selection from active product lines.

Substitute Part Grouping Explanation

Substitution eligibility for the UPJ1V271MPD is determined by the following critical parameters:

Electrical Match: Capacitance (270 µF), voltage rating (35 V), and tolerance (±20%) must be identical
Physical Compatibility: Lead spacing (5.00mm) and case diameter (10.00mm) must match for direct PCB mounting without layout modification
Thermal Performance: Operating temperature range (-55°C ~ 105°C) must be maintained
Regulatory Compliance: ROHS3 compliance required for environmental standards

Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Equivalents maintain identical electrical and mechanical specifications with only packaging format differences (Bulk vs. Cut Tape).

Similar Substitutes share core electrical parameters and physical dimensions but may differ in series designation, lifetime rating, impedance characteristics, or application focus (general purpose vs. automotive).

Upgrade Substitutes exceed the performance specifications of the original part while maintaining physical and electrical compatibility, offering extended lifetime or improved electrical characteristics.

Engineering Selection Recommendations

Direct Equivalent Selection: UPJ1V271MPD1TD is the direct equivalent of UPJ1V271MPD, differing only in packaging format (Cut Tape vs. Bulk). Both parts share identical electrical specifications and physical dimensions. Selection between these two depends solely on procurement and assembly requirements.

Nichicon Series Upgrade: UPM1V271MPD offers improved impedance performance (70 mOhms vs. 110 mOhms) while maintaining identical capacitance, voltage, and tolerance specifications. The UPM series includes AEC-Q200 automotive qualification, though both UPJ and UPM series are classified as "Not For New Designs." Height increases by 0.50mm (22.00mm vs. 21.50mm), requiring PCB clearance verification.

Active Product Line Substitutes: B41890A7277M (EPCOS - TDK Electronics), EEU-FC1V271, EEU-FC1V271B (Panasonic), and ELXZ350ELL271MH20D (Chemi-Con) are all active products suitable for new designs. These parts maintain the core electrical specifications (270 µF, 35 V, ±20%) and standard lead spacing (5.00mm).

Performance Considerations: B41890A7277M provides the longest operational lifetime (10000 Hrs @ 105°C vs. 5000 Hrs) and lowest impedance (62 mOhms), making it suitable for applications requiring extended reliability. EEU-FC1V271 and EEU-FC1V271B offer compact height (16.00mm and 17.00mm respectively) compared to the original part (21.50mm), beneficial for space-constrained designs. Both Panasonic parts carry AEC-Q200 automotive qualification.

Physical Constraint: ELXZ350ELL271MH20D has reduced lead spacing (4.60mm vs. 5.00mm) and smaller case diameter (8.00mm vs. 10.00mm), requiring PCB layout modification and is not recommended as a direct substitute without design review.

Frequently Asked Questions (FAQ)

Q: Can UPJ1V271MPD1TD be used as a direct replacement for UPJ1V271MPD?

A: Yes. UPJ1V271MPD1TD is electrically and mechanically identical to UPJ1V271MPD. The only difference is packaging format: UPJ1V271MPD1TD is supplied in Cut Tape (CT) format while UPJ1V271MPD is supplied in Bulk. Both parts are suitable for identical applications without any circuit or PCB modifications.

Q: What is the difference between the UPJ and UPM series from Nichicon?

A: Both UPJ and UPM series share identical electrical specifications for the 270 µF, 35 V rating. The UPM series offers lower impedance (70 mOhms vs. 110 mOhms) and includes AEC-Q200 automotive qualification. The UPM series has a maximum height of 22.00mm compared to 21.50mm for the UPJ series. Both series are classified as "Not For New Designs."

Q: Why is ELXZ350ELL271MH20D not recommended as a direct substitute?

A: ELXZ350ELL271MH20D has different physical dimensions: lead spacing of 4.60mm (vs. 5.00mm) and case diameter of 8.00mm (vs. 10.00mm). These differences require PCB layout modification and cannot be used as a drop-in replacement without design review and potential rework.

Q: Which substitute part is best for new designs?

A: B41890A7277M (EPCOS - TDK Electronics) is recommended for new designs requiring maximum reliability, offering 10000 Hrs lifetime at 105°C and the lowest impedance (62 mOhms). For applications requiring automotive qualification, EEU-FC1V271 or EEU-FC1V271B (Panasonic) are suitable alternatives with AEC-Q200 certification and active product status.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, meeting environmental regulatory requirements equivalent to the original UPJ1V271MPD.

Q: What is the impact of different impedance values on circuit performance?

A: Impedance affects ripple current handling and high-frequency performance. Lower impedance values (62-80 mOhms) provide better performance in high-frequency applications. The original UPJ1V271MPD has 110 mOhms impedance. Substitutes with lower impedance values (B41890A7277M at 62 mOhms, EEU-FC series at 68 mOhms) offer improved electrical characteristics for the same capacitance and voltage rating.

Q: Can I use a substitute part with different height dimensions?

A: Height differences require PCB clearance verification. EEU-FC1V271 (16.00mm) and EEU-FC1V271B (17.00mm) are shorter than the original (21.50mm), which is generally acceptable. UPM1V271MPD (22.00mm) and B41890A7277M (22.00mm) are slightly taller and require confirmation that no components or enclosure interference exists at the increased height.
