Substitute Part Grouping Explanation

Substitution for the UPW2W2R2MPD is determined by strict electrical and mechanical compatibility criteria. All substitute parts must maintain the following parameters:

Capacitance: 2.2 µF (exact match)
Tolerance: ±20% (exact match)
Voltage Rating: 450 V (exact match or higher)
Polarization: Polar (exact match)
Lead Spacing: 0.197" (5.00mm) (exact match)
Diameter: 0.394" (10.00mm) (exact match)
Mounting Type: Through Hole (exact match)
Package Type: Radial, Can (exact match)
RoHS Compliance: ROHS3 Compliant (exact match)

Substitutes are grouped into three categories based on manufacturer and product status: MFR Recommended (Nichicon UVZ2W2R2MPD), Similar alternatives (Nichicon UPS2W2R2MPD and UVY2W2R2MPD), and Direct equivalents (Panasonic ECA-2WHG2R2 and ECA-2WHG2R2B). Lifetime ratings and ripple current specifications vary among substitutes but do not affect basic electrical compatibility for general-purpose applications.

Engineering Selection Recommendations

For applications currently using the UPW2W2R2MPD, the Panasonic ECA-2WHG2R2 and ECA-2WHG2R2B represent the most suitable long-term alternatives. Both parts maintain active product status and full ROHS3 compliance, ensuring continued availability and regulatory alignment. The ECA-2WHG2R2B variant includes AEC-Q200 automotive qualification, making it appropriate for automotive-grade applications.

The Nichicon UVZ2W2R2MPD serves as the manufacturer-recommended substitute within the Nichicon product family. While classified as "Not For New Designs," it provides direct electrical compatibility with reduced height (0.492" vs. 0.787") and lower lifetime rating (2000 hours vs. 5000 hours).

The Nichicon UPS2W2R2MPD and UVY2W2R2MPD are classified as similar alternatives. The UPS2W2R2MPD maintains identical ripple current specifications but exhibits greater height (0.866"). The UVY2W2R2MPD features reduced physical dimensions (0.315" diameter, 0.512" height) and lower ripple current ratings, requiring PCB layout verification before implementation.

For new designs, selection should prioritize active-status components: ECA-2WHG2R2 or ECA-2WHG2R2B from Panasonic.

Frequently Asked Questions (FAQ)

Q: Can UVY2W2R2MPD be used as a direct replacement for UPW2W2R2MPD?

A: UVY2W2R2MPD is not a direct replacement due to mechanical incompatibility. The lead spacing is 0.138" (4.60mm) versus the required 0.197" (5.00mm), and the diameter is 0.315" (8.00mm) versus 0.394" (10.00mm). PCB layout modification is required.

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

A: Both parts are electrically and mechanically identical. ECA-2WHG2R2B includes AEC-Q200 automotive qualification and is supplied in Cut Tape (CT) packaging, while ECA-2WHG2R2 is supplied in Bulk packaging. Selection depends on application requirements and packaging preference.

Q: Why does UPW2W2R2MPD have a longer lifetime rating than substitute parts?

A: The UPW series is rated for 5000 hours at 105°C, while most substitutes are rated for 2000 hours or less. This difference reflects design generation and manufacturing process evolution. For applications requiring extended lifetime performance, verify that the substitute's 2000-hour rating meets system requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, ensuring regulatory alignment with current environmental standards.

Q: Which substitute part has the smallest physical footprint?

A: The Nichicon UVY2W2R2MPD has the smallest dimensions at 0.315" diameter and 0.512" height. However, its non-standard lead spacing (0.138" vs. 0.197") requires PCB redesign.
