UPJ1C271MPD6 Equivalent & Substitute Parts

Part Overview

The UPJ1C271MPD6 is a 270 µF, 16 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 obsolescence status, equivalent and substitute parts from active manufacturers or alternative packaging configurations are necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the UPJ1C271MPD6 is determined by strict equivalence across the following parameters: capacitance (270 µF), voltage rating (16 V), tolerance (±20%), polarization (polar), mounting type (through hole), and package configuration (radial, can). Parts are grouped into three categories:

Direct Equivalents (Packaging Variant): UPJ1C271MPD6TD differs only in packaging format (Cut Tape vs. Bulk) while maintaining identical electrical specifications and physical dimensions.

Similar Parts (Same Electrical Specs, Different Physical Dimensions or Lifetime): UPJ1C271MPD, UPM1C271MPD, and UPM1C271MPD6 share the same capacitance, voltage, and tolerance but vary in lead spacing, can diameter, height, and/or lifetime ratings. UPM series parts include AEC-Q200 automotive qualification.

Upgrade Parts (Higher Voltage Rating): B41858C5277M000 and B41888C7277M provide higher voltage ratings (25 V and 35 V respectively) while maintaining 270 µF capacitance and 5000+ hour lifetimes. These are suitable for applications requiring voltage margin.

Active Manufacturer Alternatives (Same Specs, Different Manufacturer): ELXY160ELL271MJC5S (Chemi-Con), EEU-FC1C271, EEU-FC1C271B, and EEU-FC1C271BJ (Panasonic) provide equivalent electrical performance with active product status and AEC-Q200 certification.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): UPJ1C271MPD6TD is the direct equivalent, differing only in packaging format (Cut Tape vs. Bulk). Selection depends on assembly process requirements.

For Active Product Status with Equivalent Performance: ELXY160ELL271MJC5S (Chemi-Con) provides identical electrical and physical specifications with Active product status and AEC-Q200 automotive qualification. This part is recommended for new designs and ongoing production requiring a qualified alternative.

For Automotive Applications with Enhanced Reliability: UPM1C271MPD6 (Nichicon UPM series) offers 5000-hour lifetime with AEC-Q200 qualification and lower impedance (140 mOhms vs. 220 mOhms), suitable for automotive environments despite Not For New Designs status.

For Voltage Margin Applications: B41858C5277M000 (25 V) or B41888C7277M (35 V) from EPCOS-TDK provide higher voltage ratings with Active product status, lower impedance, and extended lifetime (7000 hours for 35 V variant). These are suitable when circuit design permits higher voltage components.

For Space-Constrained Applications: EEU-FC1C271BJ (Panasonic) offers the smallest height (0.492") among equivalent parts, though with reduced lifetime (2000 hours) and Active product status with AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can UPJ1C271MPD6 be replaced with UPJ1C271MPD? A: Electrical substitution is possible (same capacitance, voltage, tolerance, and temperature range). However, UPJ1C271MPD has reduced lifetime (3000 hours vs. 5000 hours) and different physical dimensions (smaller diameter and lead spacing). PCB layout verification is required before substitution.

Q: What is the difference between UPJ1C271MPD6 and UPJ1C271MPD6TD? A: These parts are electrically and physically identical. The only difference is packaging: UPJ1C271MPD6 is supplied in Bulk, while UPJ1C271MPD6TD is supplied in Cut Tape (CT). Selection depends on assembly equipment compatibility.

Q: Can I use ELXY160ELL271MJC5S as a direct replacement? A: Yes. ELXY160ELL271MJC5S matches all critical parameters (270 µF, 16 V, ±20%, 5000 hours @ 105°C, identical physical dimensions). It offers the advantage of Active product status and AEC-Q200 automotive qualification, making it suitable for new designs.

Q: Why would I choose a higher voltage part like B41858C5277M000? A: Higher voltage ratings provide design margin for applications subject to voltage transients or where circuit topology benefits from reduced stress on the capacitor. B41858C5277M000 (25 V) and B41888C7277M (35 V) maintain 270 µF capacitance while offering Active product status and improved reliability metrics.

Q: Are Panasonic EEU-FC series parts compatible with the original footprint? A: Compatibility depends on specific part selection. EEU-FC1C271 and EEU-FC1C271BJ have different lead spacing (0.138" vs. 0.197") and smaller diameters than UPJ1C271MPD6, requiring PCB layout modification. EEU-FC1C271B has matching lead spacing (0.197") but different height and diameter.

Q: What does AEC-Q200 qualification mean for capacitor selection? A: AEC-Q200 is an automotive industry standard for passive components. Parts bearing this qualification (UPM1C271MPD6, ELXY160ELL271MJC5S, EEU-FC series) have undergone stress testing and reliability validation for automotive applications. This certification is relevant for automotive or high-reliability applications.

Q: Can I use a 2000-hour lifetime capacitor (Panasonic EEU-FC series) instead of 5000-hour? A: Substitution is possible only if application requirements permit reduced lifetime. The 2000-hour rating at 105°C is significantly lower than the original 5000-hour specification. System reliability analysis is required to determine acceptability.

Q: What is the significance of impedance differences between parts? A: Impedance affects ripple current handling and high-frequency performance. Lower impedance (ELXY160ELL271MJC5S at 120 mOhms, B41888C7277M at 101 mOhms) provides better performance in switching applications. Original UPJ1C271MPD6 impedance is 220 mOhms. Substitution with lower impedance is generally favorable but requires verification that circuit design does not depend on higher impedance characteristics.
