UVC2G180MPD Equivalent & Substitute Parts

Part Overview

The UVC2G180MPD is a 18 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as Active product status and is designed for general purpose applications requiring polarized capacitive energy storage and filtering. The UVC series operates across -40°C to 105°C with a rated lifetime of 2000 hours at 105°C. Equivalent and substitute parts are identified when identical electrical specifications (capacitance, voltage rating, tolerance, and polarization) are maintained while allowing variations in physical dimensions, ripple current ratings, and operational lifetime to accommodate different circuit requirements and availability constraints.

Substitute Part Grouping Explanation

Substitution eligibility for the UVC2G180MPD is determined by strict equivalence of core electrical parameters: capacitance value (18 µF), rated voltage (400 V), tolerance (±20%), and polarization type (Polar). All identified substitutes maintain these critical specifications. Variations in the following parameters are permissible within the substitute group:

• Lifetime @ Temperature (2000 Hrs, 10000 Hrs, or 12000 Hrs @ 105°C)
• Height - Seated (Max) (0.866" to 1.043")
• Ripple Current ratings at specified frequencies
• Manufacturer and series designation
• REACH compliance status

Lead spacing (5.00mm), diameter (10.00mm), mounting type (Through Hole), and package configuration (Radial, Can) remain consistent across all substitutes to ensure mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three components meet ROHS3 compliance requirements. The UVC2G180MPD and UCY2G180MPD are both Nichicon products with REACH Affected status, while the 400BXW18MEFR10X20 (Rubycon) carries REACH Unaffected status. Selection between these substitutes depends on circuit design constraints:

The UVC2G180MPD and 400BXW18MEFR10X20 share identical maximum seated height (0.866" / 22.00mm), making them directly interchangeable in space-constrained PCB layouts. The UCY2G180MPD exhibits increased height (1.043" / 26.50mm) and extended operational lifetime (12000 Hrs @ 105°C), suitable for applications requiring enhanced thermal endurance.

Ripple current handling varies across the group. The 400BXW18MEFR10X20 provides the highest ripple current capacity at high frequency (550 mA @ 100 kHz), followed by UCY2G180MPD (470 mA @ 100 kHz). The UVC2G180MPD supports 300 mA @ 10 kHz. Component selection should align with circuit ripple current demands at the operating frequency.

Frequently Asked Questions (FAQ)

Q: Can UCY2G180MPD replace UVC2G180MPD in all applications?

A: UCY2G180MPD is electrically equivalent to UVC2G180MPD across all critical parameters (18 µF, 400 V, ±20%, Polar). The primary difference is increased height (26.50mm vs 22.00mm) and extended lifetime (12000 Hrs vs 2000 Hrs @ 105°C). Substitution is valid if PCB layout accommodates the additional 4.5mm height and if the extended lifetime does not introduce cost or supply chain constraints.

Q: Is 400BXW18MEFR10X20 compatible with UVC2G180MPD?

A: Yes. The 400BXW18MEFR10X20 maintains identical electrical specifications and physical footprint (22.00mm height, 5.00mm lead spacing, 10.00mm diameter). The Rubycon component offers higher ripple current capacity (550 mA @ 100 kHz) and REACH Unaffected status. Mechanical and electrical compatibility is confirmed.

Q: What is the impact of different ripple current ratings?

A: Ripple current rating indicates the maximum AC current the capacitor can sustain at specified frequency without exceeding temperature limits. Higher ripple current capacity (400BXW18MEFR10X20 at 550 mA @ 100 kHz) provides design margin in high-frequency switching applications. Selection should match or exceed the circuit's actual ripple current demand at the operating frequency.

Q: Are all substitutes RoHS and REACH compliant?

A: All three components are ROHS3 Compliant. REACH status differs: UVC2G180MPD and UCY2G180MPD are REACH Affected; 400BXW18MEFR10X20 is REACH Unaffected. For applications subject to REACH restrictions, the Rubycon component is the preferred choice.

Q: Can height variation affect circuit performance?

A: Height variation (22.00mm vs 26.50mm) is a mechanical consideration affecting PCB layout and component placement density. Electrical performance is not affected. Substitution is valid if the PCB design accommodates the physical dimensions of the selected component.
