Substitute Part Grouping Explanation

Substitution eligibility for the UVZ2W2R2MPD is determined by the following critical parameters:

Electrical Match: Capacitance (2.2 µF), voltage rating (450 V), and tolerance (±20%) must be identical
Thermal Performance: Lifetime rating at 105°C must meet or exceed 2000 hours
Physical Compatibility: Lead spacing (5.00 mm), diameter (10.00 mm), and height must accommodate the original PCB layout without modification
Package Configuration: Radial, can package with through-hole mounting required
Compliance: RoHS3 compliance and REACH unaffected status maintained across all substitutes

Based on these criteria, the following parts qualify as direct substitutes:

Group 1 - Nichicon Series (Same Manufacturer)

UPS2W2R2MPD (UPS series, 2000 Hrs @ 105°C, height 22.00 mm - physical incompatibility)
UVY2W2R2MPD (UVY series, 1000 Hrs @ 105°C - thermal downgrade)

Group 2 - Panasonic Series (Cross-Manufacturer)

ECA-2WHG2R2 (NHG-A series, 2000 Hrs @ 105°C, height 14.60 mm - physical incompatibility)
ECA-2WHG2R2B (NHG-A series, 2000 Hrs @ 105°C, height 14.60 mm - physical incompatibility, automotive rated)

Engineering Selection Recommendations

ECA-2WHG2R2 (Panasonic NHG-A Series)

The ECA-2WHG2R2 is the preferred substitute for new procurement. It maintains electrical equivalence (2.2 µF, 450 V, ±20%), meets the 2000-hour thermal requirement at 105°C, and carries Active product status. RoHS3 compliance is confirmed. Physical dimensions differ slightly in height (14.60 mm vs. 12.50 mm), requiring PCB layout verification for clearance. Lead spacing and diameter match the original specification. Inventory availability is high (23,662 units).

ECA-2WHG2R2B (Panasonic NHG-A Series, Automotive)

This variant is electrically and thermally identical to ECA-2WHG2R2 but includes AEC-Q200 automotive qualification and is supplied in Cut Tape packaging. Height dimension is identical (14.60 mm). Selection is appropriate for automotive applications or where AEC-Q200 certification is required. Inventory is lower (2,629 units).

UPS2W2R2MPD (Nichicon UPS Series)

This Nichicon substitute maintains electrical and thermal specifications (2000 Hrs @ 105°C) but exhibits a significant height increase (22.00 mm vs. 12.50 mm). Product status is Obsolete. Physical incompatibility with the original PCB layout is likely. Selection is not recommended without mechanical redesign verification.

UVY2W2R2MPD (Nichicon UVY Series)

This part represents a thermal downgrade, with lifetime reduced to 1000 hours at 105°C. Lead spacing is reduced to 4.60 mm, creating electrical incompatibility with standard 5.00 mm pitch PCB layouts. Selection is not recommended.

Frequently Asked Questions (FAQ)

Q: Can I use ECA-2WHG2R2 as a direct replacement without PCB modification?

A: Electrical and thermal specifications are fully compatible. However, the height dimension increases from 12.50 mm to 14.60 mm. Verify clearance above the component on your PCB. Lead spacing (5.00 mm) and diameter (10.00 mm) remain unchanged, so through-hole mounting holes require no adjustment.

Q: What is the difference between ECA-2WHG2R2 and ECA-2WHG2R2B?

A: Both parts are electrically and thermally identical with matching physical dimensions. ECA-2WHG2R2B includes AEC-Q200 automotive qualification and is supplied in Cut Tape packaging instead of Bulk. Select ECA-2WHG2R2B for automotive applications or where tape packaging is required.

Q: Why is UPS2W2R2MPD not recommended as a substitute?

A: While UPS2W2R2MPD maintains the required 2000-hour thermal rating at 105°C, its height of 22.00 mm exceeds the original 12.50 mm specification by 9.50 mm. This creates a significant physical incompatibility with the original PCB layout. Additionally, UPS2W2R2MPD is classified as Obsolete, limiting future availability.

Q: Is UVY2W2R2MPD suitable for my application?

A: UVY2W2R2MPD is not recommended. It provides only 1000 hours at 105°C, which is half the thermal rating of the original part. Additionally, its lead spacing of 4.60 mm is incompatible with the standard 5.00 mm PCB pitch, requiring PCB rework.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts—UPS2W2R2MPD, UVY2W2R2MPD, ECA-2WHG2R2, and ECA-2WHG2R2B—are RoHS3 compliant and REACH unaffected.

Q: What is the inventory status for each substitute?

A: ECA-2WHG2R2 has the highest availability (23,662 units). UVY2W2R2MPD has 9,681 units. UPS2W2R2MPD has 1,049 units. ECA-2WHG2R2B has 2,629 units. The original UVZ2W2R2MPD has 3,431 units remaining.
