Key Parameters

Substitute Part Grouping Explanation

Substitution of the UBW1C221MPD is based on the following criteria:

Maintained Parameters (Must Match):

• Capacitance: 220 µF
• Tolerance: ±20%
• Operating Temperature Range: -55°C to 135°C
• Lifetime @ Temperature: 2000 Hrs @ 135°C
• Lead Spacing: 5.00 mm
• Package / Case: Radial, Can
• Mounting Type: Through Hole
• Series: UBW
• Manufacturer: Nichicon

Variable Parameters (Allowed to Differ):

• Voltage - Rated: May increase from 16 V to higher ratings
• Ripple Current: May increase with voltage rating
• Impedance: May decrease with voltage rating
• Physical Dimensions: Remain consistent within series

The UBW1E221MPD qualifies as a direct substitute because it maintains all critical mechanical and thermal specifications while providing enhanced electrical performance through increased voltage rating.

Engineering Selection Recommendations

Both the UBW1C221MPD and UBW1E221MPD maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between these parts depends on circuit voltage requirements:

Select UBW1C221MPD when:

• Circuit maximum voltage does not exceed 16 V
• Space or cost constraints favor the lower voltage rating
• Original design specifications explicitly require 16 V rating

Select UBW1E221MPD when:

• Circuit voltage may reach or exceed 16 V
• Enhanced ripple current handling is required
• Lower impedance performance is beneficial
• Higher voltage margin provides additional design safety

Both parts share identical mechanical footprints, thermal characteristics, and compliance certifications, enabling direct PCB-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can UBW1E221MPD replace UBW1C221MPD in existing designs?

A: Yes. The UBW1E221MPD provides identical mechanical compatibility and thermal performance. The 25 V rating accommodates all applications designed for 16 V operation. No PCB modifications are required.

Q: What is the primary difference between these parts?

A: The voltage rating increases from 16 V to 25 V. This results in improved ripple current capacity (340 mA vs 310 mA @ 120 Hz) and reduced impedance (100 mOhms vs 150 mOhms).

Q: Are the physical dimensions identical?

A: Yes. Both parts maintain 10.00 mm diameter and 14.50 mm maximum seated height. Lead spacing remains 5.00 mm, ensuring identical through-hole mounting compatibility.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both UBW1C221MPD and UBW1E221MPD are rated for automotive applications and maintain ROHS3 and REACH compliance.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 135°C with 2000-hour lifetime rating at 135°C.

Q: Can UBW1C221MPD replace UBW1E221MPD?

A: No. The UBW1C221MPD has a lower voltage rating (16 V vs 25 V) and is not suitable for circuits designed for the higher voltage specification.
