UCA2D100MPD Equivalent & Substitute Parts

Part Overview

The Nichicon UCA2D100MPD is a 10 µF, 200 V aluminum electrolytic capacitor in radial, can package with a rated lifetime of 10,000 hours at 105°C. This part is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for production and field replacement applications. Substitute parts maintain the same capacitance and voltage rating while offering improved product status, extended operating temperature ranges, or higher voltage ratings for enhanced circuit reliability.

Substitute Part Grouping Explanation

Substitution of the UCA2D100MPD is determined by the following critical parameters: capacitance (10 µF), voltage rating (200 V minimum), tolerance (±20%), polarization (polar), package type (radial can), lead spacing (5.00 mm), and physical dimensions (10.00 mm diameter, 17.50 mm height maximum). Parts are grouped into three categories:

Direct Equivalents (Same Voltage Rating): Parts maintaining 200 V rating with identical electrical and mechanical specifications. These include UCA2D100MPD1TD (Nichicon, cut tape packaging) and 200BXC10MEFC10X16 (Rubycon, bulk packaging).

Manufacturer Recommended Substitutes (Active Status): UCS2D100MPD (Nichicon, active product status) operates at 200 V with 8,000 hour lifetime at 105°C and extended operating temperature range (-40°C to 105°C).

Voltage Upgrades (Higher Voltage Rating): Parts rated at 250 V, 350 V, 400 V, or 450 V maintain the same 10 µF capacitance and physical dimensions while providing increased voltage margin. These include Rubycon BXC series (250BXC10MEFC10X16, 350BXC10MEFC10X16, 400BXC10MEFC10X16, 450BXC10MEFC10X16), Nichicon UCY2G100MPD (400 V), Rubycon BXW series (450BXW10MEFR10X16), and Chemi-Con EKXJ401ELL100MJ16S (400 V, automotive rated).
