Substitute Part Grouping Explanation

Substitution eligibility for the UPW2D470MHD is determined by the following critical parameters:

Primary Substitution Criteria:

Capacitance: 47 µF (exact match required)
Voltage Rating: 200 V minimum (higher voltage ratings are acceptable)
Tolerance: ±20% (exact match)
Polarization: Polar (exact match)
Mounting Type: Through Hole (exact match)
Lead Spacing: 0.197" (5.00 mm) (exact match for PCB compatibility)
Package Type: Radial, Can (exact match)

Secondary Considerations:

Lifetime rating: Higher lifetime ratings provide improved reliability margins
Ripple current capability: Higher ratings indicate better performance under AC stress
Physical dimensions: Case diameter and height must accommodate PCB layout constraints
Product status: Active parts are preferred over obsolete alternatives

Parts are grouped into three categories based on substitution relationship:

Direct Substitutes (Recommended): UCS2D470MHD, UCY2D470MHD3 — identical electrical specifications with improved lifetime ratings and active product status.

Manufacturer Recommended Substitute: UCS2E470MHD — same capacitance and tolerance with elevated voltage rating (250 V), providing additional safety margin.

Similar Alternatives: UAQ2D470MHD6, UAQ2D470MPD, UAS2D470MHD6, UAS2D470MPD, UCY2D470MPD, UPM2D470MHD, URZ2D470MHD — parts meeting core electrical parameters with variations in lifetime, ripple current, or physical dimensions.

Engineering Selection Recommendations

For Direct Replacement (Preferred): UCS2D470MHD and UCY2D470MHD3 are the primary substitutes. Both maintain identical electrical specifications (47 µF, 200 V, ±20% tolerance) with the same lead spacing (5.00 mm) and case diameter (12.50 mm). Both are active products with ROHS3 compliance. UCS2D470MHD offers 10000-hour lifetime at 105°C, while UCY2D470MHD3 provides 12000-hour lifetime. The UCY2D470MHD3 is subject to REACH regulations, whereas UCS2D470MHD is REACH unaffected. Height reduction from 25.00 mm to 21.50 mm improves PCB layout flexibility.

For Elevated Voltage Applications: UCS2E470MHD is the manufacturer-recommended substitute when circuit design permits 250 V operation. This part provides identical form factor and lead spacing with enhanced voltage margin. Active product status and ROHS3 compliance are maintained.

For Space-Constrained Designs: UCY2D470MPD reduces case diameter to 10.00 mm while maintaining 12000-hour lifetime and 200 V rating. Lead spacing remains 5.00 mm. Height increases to 21.50 mm, requiring PCB layout verification.

For Cost-Optimized Designs: UAQ series parts (UAQ2D470MHD6, UAQ2D470MPD, UAS2D470MHD6, UAS2D470MPD) are active alternatives with reduced lifetime ratings (2000 hours at 105°C). These are suitable for non-critical applications where extended operational life is not required. Ripple current capability is lower than the original part.

Parts to Avoid: UPM2D470MHD and URZ2D470MHD have different lead spacing (7.50 mm vs. 5.00 mm), requiring PCB redesign. UPM2D470MHD is obsolete. URZ2D470MHD has minimal lifetime rating (1000 hours).

Frequently Asked Questions (FAQ)

Q: Can UCS2D470MHD directly replace UPW2D470MHD without PCB modification? A: Yes. Both parts share identical lead spacing (5.00 mm), case diameter (12.50 mm), and electrical specifications. UCS2D470MHD is 4.60 mm shorter (21.50 mm vs. 25.00 mm), which does not affect electrical function or mechanical fit on standard PCB layouts.

Q: What is the difference between UCS2D470MHD and UCY2D470MHD3? A: Both are direct substitutes with identical form factor and electrical ratings. UCY2D470MHD3 provides extended lifetime (12000 hours vs. 10000 hours at 105°C) and higher ripple current capability. UCY2D470MHD3 is subject to REACH regulations; UCS2D470MHD is REACH unaffected. Selection depends on regulatory requirements and reliability margins.

Q: Why do some substitute parts have different case diameters? A: Nichicon offers the same capacitance and voltage in multiple physical formats. Parts with 10.00 mm diameter (UCY2D470MPD, UAQ2D470MPD, UAS2D470MPD) are designed for space-constrained applications. These require PCB layout verification to confirm lead spacing and height compatibility.

Q: Can I use UCS2E470MHD (250 V) in place of UPW2D470MHD (200 V)? A: Yes. Higher voltage ratings are electrically compatible with lower voltage designs. UCS2E470MHD maintains identical form factor and lead spacing. This substitution is suitable when circuit design permits the elevated voltage rating and when manufacturer recommendation is acceptable.

Q: What is the impact of using UAQ series parts with 2000-hour lifetime? A: UAQ series parts are suitable for applications where component operational life does not exceed 2000 hours at 105°C. These parts have lower ripple current ratings (195 mA @ 120 Hz vs. 220 mA for the original). Use only in non-critical applications or where thermal stress is minimal.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant. UCY2D470MHD3 and UCY2D470MPD are subject to REACH regulations; all others are REACH unaffected. Verify regulatory compliance requirements for your specific application.

Q: Why is UPM2D470MHD not recommended as a substitute? A: UPM2D470MHD has different lead spacing (7.50 mm vs. 5.00 mm), requiring PCB redesign. Additionally, this part is obsolete, making long-term procurement difficult. Use UCS2D470MHD or UCY2D470MHD3 instead.
