Substitute Part Grouping Explanation

Substitution for the UVR2W2R2MPD1TD is determined by strict equivalence across the following electrical and mechanical parameters:

Capacitance Value: 2.2 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Package Configuration: Radial, Can (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Case Diameter: 0.394" (10.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)

Two substitute parts meet these core electrical and mechanical criteria. The substitutes are differentiated by their thermal performance characteristics and product status:

ECA-2WM2R2B (Panasonic): Direct equivalent with identical electrical specifications and Active product status
ECA-2WHG2R2B (Panasonic): Upgraded variant with extended temperature range and automotive-grade certification

Engineering Selection Recommendations

For Direct Replacement (Maintenance/Legacy Support): The ECA-2WM2R2B is the appropriate choice for direct substitution. It maintains identical electrical specifications and thermal performance to the UVR2W2R2MPD1TD while offering Active product status from Panasonic. This part is suitable for applications requiring exact performance matching in existing designs. The slightly reduced maximum height (14.60 mm vs. 14.00 mm) presents no compatibility issues for standard through-hole PCB layouts.

For Design Upgrades (New Designs/Enhanced Reliability): The ECA-2WHG2R2B is recommended for applications requiring extended operating temperature range or automotive-grade reliability. This part carries AEC-Q200 certification and supports operation to 105°C, providing enhanced thermal margin and long-term reliability. The extended temperature capability makes this part suitable for harsh environment applications while maintaining full electrical equivalence.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can ECA-2WM2R2B be used as a direct drop-in replacement for UVR2W2R2MPD1TD? A: Yes. The ECA-2WM2R2B is electrically and mechanically equivalent. Both parts share identical capacitance (2.2 µF), voltage rating (450 V), tolerance (±20%), lead spacing (5.00 mm), and case diameter (10.00 mm). The height difference of 0.5 mm (14.60 mm vs. 14.00 mm) does not affect PCB compatibility for standard through-hole designs.

Q: What is the difference between ECA-2WM2R2B and ECA-2WHG2R2B? A: Both parts are electrically equivalent at the rated specifications. The primary differences are: (1) ECA-2WHG2R2B supports extended operating temperature to 105°C versus 85°C for ECA-2WM2R2B; (2) ECA-2WHG2R2B carries AEC-Q200 automotive certification; (3) ECA-2WHG2R2B is rated for 2000 hours at 105°C versus 85°C for ECA-2WM2R2B. Select ECA-2WHG2R2B for applications requiring higher temperature performance or automotive compliance.

Q: Are there any PCB layout considerations when substituting these parts? A: No. All three parts use identical lead spacing (5.00 mm) and case diameter (10.00 mm). The substitute parts are slightly shorter (14.60 mm vs. 14.00 mm), which presents no clearance issues for standard through-hole mounting. Existing PCB designs require no modification.

Q: Why is the UVR2W2R2MPD1TD marked as Not For New Designs? A: This designation indicates the part has been discontinued from Nichicon's active product line. For new designs, select either ECA-2WM2R2B (direct equivalent, Active status) or ECA-2WHG2R2B (upgraded performance, Active status, automotive-grade).

Q: Do these parts have different ripple current ratings? A: Yes. At 120 Hz, ECA-2WM2R2B is rated for 44 mA, ECA-2WHG2R2B for 29 mA, and the original UVR2W2R2MPD1TD for 35 mA. For applications with specific ripple current requirements, verify the substitute part meets or exceeds the design specification. ECA-2WM2R2B provides the highest ripple current capability at low frequency.
