Substitute Part Grouping Explanation
Substitution relationships are established based on the following criteria:
Direct Equivalents maintain identical electrical specifications (150 µF, 16 V, ±20% tolerance, 2000 Hrs @ 105°C) and package footprint (0.260" L x 0.260" W land size, 6.30mm diameter). Variations in height, ripple current handling, and impedance are acceptable within the same voltage and capacitance class.
Upgrade Parts provide higher voltage ratings (25 V) or improved electrical performance (lower impedance, higher ripple current capacity) while maintaining the same capacitance and package footprint. These are suitable for applications requiring additional design margin.
Similar Parts match electrical specifications but differ in packaging format (Cut Tape vs. Tape & Reel) or series designation. Mechanical compatibility remains equivalent.
Parametric Equivalents from alternative manufacturers (Würth Elektronik, Panasonic) meet the same electrical and mechanical requirements with comparable performance characteristics.

Engineering Selection Recommendations
For AEC-Q200 Automotive Applications: UCD1C151MCL1GS, UCM1E151MCL1GS, UUD1C151MCL1GS, EEE-FPC151XAP, EEE-FT1C151AL, EEE-FT1C151AP, and EEE-FKC151XAL all carry AEC-Q200 certification and are suitable for automotive-grade designs. UCM1E151MCL1GS provides upgraded voltage margin (25 V) with improved ripple current handling.
For General Purpose Applications: UWD1C151MCL1GS, UCL1C151MCL1GS, 865060345006, and 865080345010 are qualified for general purpose use without automotive certification. These parts maintain electrical equivalence to the primary specification.
For Height-Constrained Layouts: EEE-FT1C151AL and EEE-FT1C151AP offer reduced height (0.240" / 6.10mm) compared to the standard 0.315" (8.00mm) profile, enabling compact board designs while maintaining electrical performance.
For Improved Electrical Performance: UCL1C151MCL1GS, EEE-FPC151XAP, EEE-FT1C151AL, and EEE-FT1C151AP feature lower impedance (160–260 mOhms) and higher ripple current capacity (300–600 mA @ 100 kHz), beneficial for high-frequency switching applications.
For Supply Chain Continuity: Panasonic (EEE series) and Würth Elektronik (WCAP series) provide independent sourcing alternatives to Nichicon UCD/UWD/UCM/UCL/UUD series, reducing single-source dependency.
Frequently Asked Questions (FAQ)
Q: Can UWD1C151MCL1GS replace UCD1C151MCL1GS in automotive applications?
A: UWD1C151MCL1GS is not AEC-Q200 certified. For automotive designs requiring qualification compliance, use AEC-Q200 rated alternatives: UCD1C151MCL1GS, UUD1C151MCL1GS, UCM1E151MCL1GS, or Panasonic EEE-FT/EEE-FPC/EEE-FKC series.
Q: What is the difference between Tape & Reel and Cut Tape packaging?
A: Tape & Reel packaging is supplied on continuous reels for automated pick-and-place assembly. Cut Tape & Digi-Reel packaging is pre-cut into smaller quantities for manual or lower-volume assembly. Both formats use identical component specifications and land patterns.
Q: Is UCM1E151MCL1GS a direct replacement for UCD1C151MCL1GS?
A: UCM1E151MCL1GS is an upgrade, not a direct replacement. It provides higher voltage rating (25 V vs. 16 V), lower impedance (160 mOhms vs. 320 mOhms), and higher ripple current capacity (600 mA vs. 290 mA @ 100 kHz). It is electrically compatible and physically interchangeable on the same PCB footprint, offering improved performance margin.
Q: Can I use EEE-FT1C151AL instead of UCD1C151MCL1GS in space-constrained designs?
A: Yes. EEE-FT1C151AL is AEC-Q200 certified, matches all electrical specifications (150 µF, 16 V, 2000 Hrs @ 105°C), and uses the same land pattern (0.260" L x 0.260" W). Its reduced height (0.240" vs. 0.315") makes it suitable for compact layouts. Verify PCB clearance above the component.
Q: What are the impedance differences among substitute parts?
A: Impedance ranges from 160 mOhms (UCL1C151MCL1GS, EEE-FPC151XAP, EEE-FT series) to 450 mOhms (865080345010). Lower impedance parts provide better high-frequency performance and lower voltage ripple. Selection depends on circuit requirements for ripple current handling and frequency response.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts carry RoHS3 compliance certification. REACH status varies: Nichicon UCD/UWD/UCM/UUD and Würth Elektronik parts are REACH Affected; Panasonic EEE series and Würth 865060345006 are REACH Unaffected. Verify REACH compliance requirements for your application region.
Q: Can I mix different manufacturers in the same production batch?
A: Yes, provided all parts meet the same electrical specifications (150 µF, 16 V, ±20%, 2000 Hrs @ 105°C) and use identical land patterns (0.260" L x 0.260" W). For automotive applications, ensure all parts carry AEC-Q200 certification. Document manufacturer and part number for traceability.
