UCD1H100MCL1GS Equivalent & Substitute Parts

Part Overview

The UCD1H100MCL1GS is a 10 µF, 50 V aluminum electrolytic capacitor manufactured by Nichicon in the UCD series. This surface mount radial can capacitor is rated for 2000 hours at 105°C and meets AEC-Q200 automotive qualification standards. The part is active and available in Tape & Reel packaging with 951 units in stock.

Substitute parts are identified when design requirements allow flexibility in packaging format, thermal lifetime rating, voltage rating, or manufacturer selection while maintaining core electrical and mechanical compatibility within the 10 µF, 50 V parameter space and compatible physical dimensions.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Substitutes (Same Electrical & Mechanical Specifications): Parts sharing identical capacitance (10 µF), voltage rating (50 V), tolerance (±20%), physical dimensions (0.248" Dia, 0.240" height max), surface mount land size (0.260" L x 0.260" W), and thermal lifetime (2000 Hrs @ 105°C) are classified as direct substitutes. Packaging format differences (Tape & Reel vs. Cut Tape) do not affect electrical compatibility.

Direct Substitutes with Packaging Variation: UUD1H100MCL1GS (Nichicon) differs only in packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel) and minor ripple current specifications (82.5 mA vs. 85 mA @ 120 Hz; 165 mA vs. 170 mA @ 100 kHz). All other parameters remain identical.

Upgrade Substitutes (Enhanced Thermal Lifetime): UUA1H100MCL1GS (Nichicon) provides extended thermal lifetime (3000 Hrs @ 105°C vs. 2000 Hrs) while maintaining all other core specifications. Height is reduced to 0.228" (5.80mm), remaining within mechanical compatibility.

Parametric Equivalents (Same Electrical, Voltage-Upgraded Options): AFK106M63D16T-F and EEE-FK1J100P operate at 63 V rating (vs. 50 V), providing voltage margin while maintaining 10 µF capacitance and 2000 Hrs @ 105°C lifetime. These are suitable where higher voltage headroom is acceptable.

Parametric Equivalents (Same Electrical, Same Voltage): 50TZV10M6.3X6.1, 50SGV10M6.3X6.1, EEE-FK1H100L, EEE-FK1H100P, and EMZA500ARA100MF61G maintain identical 10 µF, 50 V, 2000 Hrs @ 105°C specifications with compatible physical dimensions across multiple manufacturers (Rubycon, Panasonic, Chemi-Con).

Engineering Selection Recommendations

For Automotive Applications (AEC-Q200 Required): UCD1H100MCL1GS, UUD1H100MCL1GS, AFK106M50D16T-F, AFK106M63D16T-F, 50TZV10M6.3X6.1, 50SGV10M6.3X6.1, EEE-FK1H100L, EEE-FK1H100P, and EEE-FK1J100P all meet AEC-Q200 qualification. UUA1H100MCL1GS does not carry AEC-Q200 rating and is classified for general purpose applications.

For Extended Thermal Life (3000 Hrs @ 105°C): UUA1H100MCL1GS is the only option providing 3000-hour thermal lifetime. This part is suitable for applications where extended operational life at elevated temperature is required, provided AEC-Q200 automotive qualification is not mandatory.

For Voltage Margin (63 V Rating): AFK106M63D16T-F and EEE-FK1J100P provide 63 V rating while maintaining 10 µF capacitance and 2000 Hrs @ 105°C lifetime. These are suitable where circuit design allows higher voltage components or where voltage stress margin is a design consideration.

For Direct Replacement (Identical Specifications): UUD1H100MCL1GS is a direct electrical equivalent differing only in packaging format. Selection depends on procurement and assembly requirements for Cut Tape & Digi-Reel® versus Tape & Reel formats.

For Multi-Manufacturer Sourcing: EEE-FK1H100P (Panasonic) and 50TZV10M6.3X6.1 (Rubycon) offer high inventory availability (86,159 and 4,620 units respectively) and identical electrical specifications to the main part, supporting supply chain diversification.

Frequently Asked Questions (FAQ)

Q: Can UUD1H100MCL1GS replace UCD1H100MCL1GS directly? A: Yes. Both parts share identical electrical specifications (10 µF, 50 V, ±20%, 2000 Hrs @ 105°C) and physical dimensions. The only difference is packaging format: UUD uses Cut Tape & Digi-Reel® while UCD uses Tape & Reel. Selection depends on assembly equipment compatibility.

Q: Is UUA1H100MCL1GS suitable for automotive applications? A: UUA1H100MCL1GS does not carry AEC-Q200 automotive qualification and is rated for general purpose applications. It is not recommended for automotive designs requiring AEC-Q200 compliance. However, it provides extended thermal lifetime (3000 Hrs @ 105°C vs. 2000 Hrs) if automotive qualification is not a requirement.

Q: Can I use a 63 V rated capacitor (AFK106M63D16T-F or EEE-FK1J100P) in place of the 50 V UCD1H100MCL1GS? A: Yes, from an electrical standpoint. Both 63 V parts maintain 10 µF capacitance, ±20% tolerance, and 2000 Hrs @ 105°C lifetime. Higher voltage rating provides additional voltage stress margin. Verify circuit design allows the higher voltage component and confirm physical dimensions are compatible with PCB layout.

Q: What is the difference between EEE-FK1H100L and EEE-FK1H100P? A: Both are Panasonic EEE-FK series parts with identical electrical specifications (10 µF, 50 V, ±20%, 2000 Hrs @ 105°C, AEC-Q200). EEE-FK1H100L is designated as Halogen Free. EEE-FK1H100P has significantly higher inventory (86,159 units vs. 8,243 units). Selection depends on halogen-free material requirements and availability.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance status. UCD1H100MCL1GS and all direct and parametric equivalent substitutes meet ROHS3 requirements.

Q: What is the physical compatibility of substitute parts with the original PCB layout? A: All substitute parts maintain identical or compatible physical dimensions: 0.248" diameter (6.30mm), height between 0.228" and 0.240" (5.80mm to 6.10mm), and surface mount land size of 0.260" L x 0.260" W (6.60mm x 6.60mm). UUA1H100MCL1GS has slightly reduced height (0.228" vs. 0.240") but remains within mechanical compatibility. AFK106M63D16T-F and EEE-FK1J100P have surface mount land width of 0.307" W (7.80mm) versus 0.260" W (6.60mm); verify PCB pad layout compatibility before substitution.

Q: Which substitute offers the best inventory availability? A: EEE-FK1H100P (Panasonic) has the highest inventory with 86,159 units in stock, followed by EMZA500ARA100MF61G (Chemi-Con) with 42,305 units. Both maintain identical electrical specifications to UCD1H100MCL1GS.
