Substitute Part Grouping Explanation

Substitution for the UPW2C3R3MPD is determined by the following critical parameters: capacitance value (3.3 µF), tolerance (±20%), voltage rating (160 V minimum), mounting type (through hole), and package configuration (radial, can). Lead spacing and physical dimensions are secondary considerations for PCB layout compatibility.

The substitute parts are grouped into three categories:

MFR Recommended: UVY2V3R3MPD offers higher voltage rating (350 V) with identical capacitance and tolerance, maintaining the same lead spacing and mounting type. Lifetime is reduced to 1000 hours at 105°C.

Upgrade: UPW2D3R3MPD shares the same series designation and lifetime rating (3000 Hrs @ 105°C) with increased voltage rating (200 V), same lead spacing, and identical physical dimensions.

Similar: UVZ2C3R3MED and EKMG161ELL3R3MF11D match the 160 V rating and 3.3 µF capacitance but feature reduced lead spacing (0.098" / 2.50mm) and smaller physical dimensions (0.248" Dia / 6.30mm). SEK3R3M160ST from Cornell Dubilier Electronics provides equivalent electrical specifications with documented ESR characteristics.

Engineering Selection Recommendations

For applications requiring direct form-factor compatibility with existing PCB layouts, UPW2D3R3MPD maintains identical lead spacing (0.138" / 4.60mm) and physical dimensions while providing increased voltage margin (200 V) and equivalent lifetime rating (3000 Hrs @ 105°C). This part remains within the Nichicon UPW series.

For new designs or where PCB layout permits reduced footprint, EKMG161ELL3R3MF11D from Chemi-Con offers active product status with compact dimensions (0.248" Dia / 6.30mm) and reduced lead spacing (0.098" / 2.50mm). This part maintains 160 V rating and ±20% tolerance with 1000-hour lifetime at 105°C.

SEK3R3M160ST from Cornell Dubilier Electronics provides an alternative from a different manufacturer with active product status, compact form factor, and documented ESR specification (60.32 Ohm @ 120 Hz). Lifetime rating is 2000 hours at 105°C.

UVY2V3R3MPD offers higher voltage capability (350 V) with maintained lead spacing but increased height (0.512" / 13.00mm) and reduced lifetime (1000 Hrs @ 105°C). This part is classified as "Not For New Designs."

All substitute parts are ROHS3 compliant and REACH unaffected, matching the original part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can UPW2D3R3MPD directly replace UPW2C3R3MPD on existing boards?

A: Yes. UPW2D3R3MPD maintains identical lead spacing (0.138" / 4.60mm), physical dimensions (0.315" Dia / 8.00mm), and height (0.453" / 11.50mm). The increased voltage rating (200 V vs. 160 V) provides additional design margin. Both parts share the same series designation and 3000-hour lifetime at 105°C.

Q: What is the primary difference between the Nichicon and Chemi-Con alternatives?

A: EKMG161ELL3R3MF11D (Chemi-Con) features a more compact footprint with reduced lead spacing (0.098" / 2.50mm) and smaller diameter (0.248" / 6.30mm). It maintains active product status and equivalent electrical specifications (3.3 µF, 160 V, ±20% tolerance) but with reduced lifetime (1000 Hrs @ 105°C vs. 3000 Hrs for UPW2C3R3MPD).

Q: Does UVY2V3R3MPD provide a suitable upgrade path?

A: UVY2V3R3MPD increases voltage rating to 350 V with identical capacitance and tolerance. However, it introduces height increase (0.512" / 13.00mm vs. 0.453" / 11.50mm) and reduced lifetime (1000 Hrs @ 105°C). This part is classified as "Not For New Designs." Use only if voltage margin is critical and PCB layout accommodates increased height.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of UPW2C3R3MPD.

Q: What is the lead spacing consideration for compact designs?

A: UVZ2C3R3MED, EKMG161ELL3R3MF11D, and SEK3R3M160ST feature reduced lead spacing (0.098" / 2.50mm) compared to the original part (0.138" / 4.60mm). These parts require PCB layout modification and are suitable only for new designs or boards with compatible hole spacing.
