UAS2D470MPD Equivalent & Substitute Parts

Part Overview

The UAS2D470MPD is a 47 µF, 200 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component operates across a temperature range of -40°C to 105°C with a rated lifetime of 2000 hours at 105°C. The part is currently active in production and ROHS3 compliant.

Equivalent and substitute parts are necessary when the original component becomes unavailable, when design requirements demand extended operational lifetime, when voltage margin improvements are needed, or when ripple current handling capacity must be increased for circuit reliability.

Substitute Part Grouping Explanation

Substitution eligibility for the UAS2D470MPD is determined by the following criteria:

Direct Substitutes maintain identical electrical specifications: 47 µF capacitance, 200 V voltage rating, ±20% tolerance, and compatible through-hole radial package with 5.00 mm lead spacing. These parts are electrically interchangeable without circuit modification.

Upgrade Substitutes increase voltage rating to 250 V while maintaining 47 µF capacitance and ±20% tolerance. These provide enhanced voltage margin and are mechanically compatible with the original footprint.

Similar Substitutes share the core electrical parameters (47 µF, 200 V, ±20% tolerance) but differ in one or more of the following: case diameter, height, lifetime rating, ripple current capacity, or product status. These require verification of mechanical fit and thermal performance in the target application.

Cross-Manufacturer Substitutes are sourced from alternative manufacturers (Rubycon, Chemi-Con, Cornell Dubilier Electronics) while maintaining equivalent electrical and mechanical specifications.

Engineering Selection Recommendations

For Direct Replacement with Enhanced Performance: UCY2D470MPD (Nichicon) is the primary direct substitute. It maintains identical electrical ratings (47 µF, 200 V, ±20% tolerance) while providing six times the operational lifetime (12000 hours versus 2000 hours at 105°C). The case diameter and lead spacing remain compatible with the original footprint. Height is reduced from 27.00 mm to 21.50 mm, which is advantageous for space-constrained layouts. Ripple current capacity is significantly increased (360 mA @ 120 Hz, 720 mA @ 100 kHz). Product status is Active with ROHS3 compliance.

For Voltage Margin Improvement: UCY2E470MPD9 (Nichicon) or EKXJ251ELL470MJ25S (Chemi-Con) upgrade the voltage rating to 250 V while maintaining 47 µF capacitance and ±20% tolerance. Both are Active products with ROHS3 compliance and 12000-hour lifetime ratings. UCY2E470MPD9 maintains the 10.00 mm case diameter of the original. EKXJ251ELL470MJ25S carries AEC-Q200 automotive qualification. Height dimensions are compatible with the original footprint.

For Cross-Manufacturer Compatibility: 200PX47MEFC10X20 (Rubycon) provides electrical equivalence with identical case diameter (10.00 mm) and lead spacing (5.00 mm). It is an Active product with ROHS3 compliance and 2000-hour lifetime matching the original specification.

Parts to Avoid for New Designs: UPM2D470MHD, UPW2D470MHD, and UVZ2D470MHD are marked as Obsolete or Not For New Designs. EKXG201ELL470MK20S is Obsolete. These should be used only when existing inventory must be consumed or when legacy system maintenance is required.

Frequently Asked Questions (FAQ)

Q: Can UCY2D470MPD be used as a direct replacement for UAS2D470MPD? A: Yes. Both parts share identical capacitance (47 µF), voltage rating (200 V), tolerance (±20%), lead spacing (5.00 mm), and case diameter (10.00 mm). The UCY2D470MPD offers superior lifetime (12000 hours versus 2000 hours) and higher ripple current capacity. Height is reduced from 27.00 mm to 21.50 mm, which is compatible with most PCB layouts.

Q: What is the difference between direct substitutes and upgrade substitutes? A: Direct substitutes maintain all electrical and mechanical parameters of the original part. Upgrade substitutes increase one or more performance parameters—typically voltage rating or lifetime—while maintaining mechanical compatibility. Upgrade substitutes are backward-compatible but provide enhanced design margin.

Q: Are parts marked as Obsolete still usable? A: Obsolete parts may be used in existing designs or legacy system maintenance when inventory is available. However, they should not be selected for new designs. Active products are recommended for all new development.

Q: Does case diameter affect PCB footprint compatibility? A: Yes. The original UAS2D470MPD has a 10.00 mm case diameter. Substitutes with larger diameters (12.50 mm or 16.00 mm) require verification that the PCB layout accommodates the increased size. Substitutes with identical or smaller diameters are mechanically compatible without layout modification.

Q: What is the significance of ripple current ratings? A: Ripple current capacity determines the maximum AC current the capacitor can handle without exceeding temperature limits. Higher ripple current ratings provide design margin for circuits with significant AC stress. Substitutes with equal or higher ripple current ratings are suitable for the same application.

Q: Can a 250 V rated capacitor replace a 200 V rated capacitor? A: Yes. A higher voltage rating provides additional safety margin and is electrically compatible. The 250 V parts (UCY2E470MPD9, EKXJ251ELL470MJ25S) can replace the 200 V original without circuit modification. This is a conservative design practice.

Q: What does ROHS3 compliance mean? A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All listed substitutes are ROHS3 compliant, ensuring regulatory compatibility.
