Substitute Part Grouping Explanation

Substitute parts for the UPJ2E2R2MPD are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

Capacitance: 2.2 µF (exact match required)
Voltage Rating: 250 V (minimum acceptable rating)
Tolerance: ±20% (standard tolerance class)
Polarization: Polar (electrolytic type)
Package: Radial, Can (through-hole mounting)
Operating Temperature: -40°C ~ 105°C (full range compatibility)
RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Secondary Considerations:

Lead Spacing: 0.197" (5.00mm) preferred for direct PCB compatibility
Physical Dimensions: Diameter 0.248" ~ 0.394" and height 0.492" ~ 0.551" acceptable within board layout constraints
Lifetime Rating: Minimum 1000 Hrs @ 105°C acceptable; higher ratings provide extended service life

Substitutes are grouped into two categories: direct equivalents (identical electrical and mechanical specifications) and compatible alternatives (same electrical performance with minor dimensional variations).

Engineering Selection Recommendations

Direct Equivalent (Preferred for Replacement):

The MAL214232283E3, MAL214252283E3, and MAL214272283E3 from Vishay Beyschlag/Draloric/BC Components are the primary substitutes for the UPJ2E2R2MPD. All three parts share identical electrical specifications (2.2 µF, 250 V, ±20%, -40°C ~ 105°C) and are classified as Active products. These parts are ROHS3 compliant and rated for 2500 hours at 105°C, exceeding the minimum lifetime requirement. The Vishay 142 RHS series provides superior availability and long-term supply continuity compared to the obsolete Nichicon UPJ series.

Alternative Substitute (Higher Voltage Rating):

The Nichicon UVZ2G2R2MPD offers a higher voltage rating (400 V) while maintaining the same 2.2 µF capacitance and ±20% tolerance. This part is suitable for applications where voltage margin is beneficial, though it is classified as Not For New Designs. The UVZ2G2R2MPD has a reduced lifetime rating of 2000 hours at 105°C compared to the original UPJ2E2R2MPD.

Secondary Alternative (Compact Form Factor):

The Chemi-Con EKMG251ELL2R2MF11D is an Active product with identical electrical specifications but features a smaller physical footprint (0.248" diameter vs. 0.394"). This part is suitable only if PCB layout permits the reduced size. The EKMG251ELL2R2MF11D has a lower lifetime rating of 1000 hours at 105°C.

Mechanical Compatibility Note:

The UPJ2E2R2MPD has a lead spacing of 0.197" (5.00mm) and diameter of 0.394" (10.00mm). The UVZ2G2R2MPD maintains identical lead spacing and diameter, providing direct mechanical compatibility. The Vishay MAL214 series and Chemi-Con EKMG series have reduced lead spacing (0.098" / 2.50mm) and smaller diameter (0.248" / 6.30mm), requiring PCB layout verification before substitution.

Frequently Asked Questions (FAQ)

Q: Can the UVZ2G2R2MPD replace the UPJ2E2R2MPD directly?

A: The UVZ2G2R2MPD is electrically compatible as a substitute. It maintains the same 2.2 µF capacitance, ±20% tolerance, and operating temperature range. However, the lifetime rating is reduced from 5000 hours to 2000 hours at 105°C. The part has identical lead spacing (0.197" / 5.00mm) and diameter (0.394" / 10.00mm), ensuring mechanical compatibility. The higher voltage rating (400 V vs. 250 V) provides additional safety margin in the circuit.

Q: What is the difference between the Vishay MAL214232283E3, MAL214252283E3, and MAL214272283E3?

A: All three Vishay parts are electrically identical (2.2 µF, 250 V, ±20%, 2500 Hrs @ 105°C) and belong to the 142 RHS series. The primary differences are packaging format (Tape & Box vs. Bulk) and lead spacing configuration. MAL214232283E3 and MAL214272283E3 are supplied in Tape & Box packaging, while MAL214252283E3 is supplied in Bulk. All three have reduced lead spacing (0.098" / 2.50mm) and smaller diameter (0.248" / 6.30mm) compared to the original UPJ2E2R2MPD.

Q: Is the Chemi-Con EKMG251ELL2R2MF11D suitable for my application?

A: The EKMG251ELL2R2MF11D is electrically compatible with the UPJ2E2R2MPD, maintaining the same 2.2 µF capacitance, 250 V rating, and ±20% tolerance. However, it has a significantly lower lifetime rating of 1000 hours at 105°C compared to the original 5000 hours. The part features a compact form factor (0.248" diameter, 0.098" lead spacing) that may not fit existing PCB layouts designed for the larger UPJ2E2R2MPD (0.394" diameter, 0.197" lead spacing). Verify PCB hole spacing and component clearance before selection.

Q: Why is the UPJ2E2R2MPD obsolete?

A: The Nichicon UPJ series has been discontinued and replaced by newer product lines. The UVZ series from Nichicon and equivalent products from Vishay and Chemi-Con offer comparable or superior performance with active manufacturing status and guaranteed long-term availability.

Q: What are the key parameters I must match when selecting a substitute?

A: The critical parameters for substitution are capacitance (2.2 µF), voltage rating (minimum 250 V), tolerance (±20%), polarization (polar), package type (radial, can), and mounting type (through hole). Operating temperature range (-40°C ~ 105°C) and RoHS compliance (ROHS3) must also be maintained. Lead spacing and physical dimensions should be verified against PCB layout requirements.

Q: Can I use a higher voltage rated capacitor as a substitute?

A: Yes. A capacitor with a higher voltage rating (such as the UVZ2G2R2MPD at 400 V) can replace the UPJ2E2R2MPD (250 V) in the same circuit. Higher voltage ratings provide additional safety margin and do not negatively affect circuit performance. However, verify that the physical dimensions and lead spacing are compatible with the PCB layout.

Q: What is the impact of reduced lifetime rating on part selection?

A: The original UPJ2E2R2MPD is rated for 5000 hours at 105°C. Substitute parts have lower lifetime ratings: UVZ2G2R2MPD (2000 Hrs), Vishay MAL214 series (2500 Hrs), and Chemi-Con EKMG251ELL2R2MF11D (1000 Hrs). For applications requiring extended service life at elevated temperatures, select substitutes with higher lifetime ratings. For general-purpose applications operating below 105°C, lower lifetime ratings are typically acceptable.
