UPW2C330MHD Equivalent & Substitute Parts

Part Overview

The UPW2C330MHD is a 33 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The UPW series has been discontinued, requiring engineers to identify functionally compatible alternatives from active product lines or equivalent series that maintain electrical and mechanical compatibility within the application requirements.

Substitute Part Grouping Explanation

Substitution for the UPW2C330MHD is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Capacitance: 33 µF (exact match required)
Voltage Rating: 160 V (minimum; higher voltage ratings are acceptable)
Tolerance: ±20% (standard tolerance match)
Polarization: Polar (required for electrolytic type)
Lead Spacing: 0.197" (5.00 mm) (mechanical compatibility)
Mounting Type: Through Hole (PCB assembly compatibility)
Package Type: Radial, Can (form factor compatibility)
Operating Temperature: -40°C ~ 105°C (functional range)

Secondary Considerations:

Lifetime @ 105°C: Substitutes may have different rated lifetimes; selection depends on application duty cycle
Ripple Current Ratings: Substitutes may have different ripple current capabilities; selection depends on circuit requirements
Physical Dimensions: Substitutes may vary in diameter and height; mechanical fit must be verified
Product Status: Active parts are preferred for new designs; obsolete or "Not For New Designs" parts are acceptable for legacy system support

Substitutes are grouped by their ability to meet these criteria while maintaining functional equivalence in the application circuit.

Engineering Selection Recommendations

For Active Product Line Preference:

UCY2C330MPD (Nichicon, Active) is the primary recommended substitute. This part maintains identical electrical specifications (33 µF, 160 V, ±20% tolerance) with superior lifetime rating (12000 Hrs @ 105°C versus 7000 Hrs). Mechanical dimensions are reduced (0.394" diameter, 0.689" height), requiring verification of PCB layout clearance. Lead spacing remains compatible at 0.197" (5.00 mm).

EKXG161ELL330MJ20S (Chemi-Con, Active) provides an alternative from a different manufacturer with equivalent electrical performance and 8000 Hrs lifetime rating. Physical dimensions are similar to UCY2C330MPD with slightly increased height (0.787" versus 0.689"), offering better mechanical stability in some applications.

For Voltage Margin Applications:

UVZ2E330MHD (Nichicon, Not For New Designs) provides 250 V rating, suitable for applications requiring voltage derating margin. Height increases to 0.866" (22.00 mm); mechanical fit must be verified. Lifetime is reduced to 2000 Hrs @ 105°C.

For Legacy System Support:

UVY2C330MPD (Nichicon, Not For New Designs) maintains exact voltage and capacitance specifications with reduced physical footprint. This part is acceptable for sustaining production of existing designs where component qualification has been completed.

SEK330M160ST (Cornell Dubilier Electronics, Active) provides cross-manufacturer equivalence with documented ESR specification (6.03 Ohm @ 120 Hz). This part is suitable for applications where ripple current performance is critical.

All substitute parts are ROHS3 compliant and maintain -40°C ~ 105°C operating temperature range compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use UVZ2E330MHD as a direct replacement for UPW2C330MHD?

A: UVZ2E330MHD is electrically compatible with higher voltage rating (250 V versus 160 V), which is acceptable in most applications. However, physical height increases from 0.787" to 0.866", requiring PCB layout verification. Lifetime rating decreases to 2000 Hrs @ 105°C; confirm application duty cycle compatibility.

Q: What is the difference between UCY2C330MPD and UVY2C330MPD?

A: Both parts share identical electrical specifications (33 µF, 160 V, ±20%) and physical dimensions (0.394" diameter, 0.689" height). UCY2C330MPD is an active product with 12000 Hrs lifetime; UVY2C330MPD is not recommended for new designs with 2000 Hrs lifetime. For new designs, UCY2C330MPD is the preferred choice.

Q: Will EKXG161ELL330MJ20S fit in the same PCB footprint as UPW2C330MHD?

A: Lead spacing is identical (0.197" / 5.00 mm), ensuring electrical connection compatibility. Diameter is reduced (0.394" versus 0.492"), and height is increased (0.787" versus 0.787"), requiring mechanical clearance verification around the component location. Verify PCB layout for any height or diameter constraints.

Q: Why does SEK330M160ST have an ESR specification while others do not?

A: ESR (Equivalent Series Resistance) is a documented parameter for SEK330M160ST (6.03 Ohm @ 120 Hz). This specification is relevant for applications with high ripple current or noise-sensitive circuits. Other substitutes do not have ESR values provided in the data; contact manufacturers for detailed specifications if ESR performance is critical.

Q: Can I use these substitutes interchangeably in production?

A: All listed substitutes meet the core electrical and mechanical requirements for the UPW2C330MHD application. However, component qualification, thermal testing, and reliability assessment should be completed before production transition. Lead spacing and physical dimensions must be verified against PCB design constraints for each substitute.

Q: Which substitute has the longest operational lifetime?

A: UCY2C330MPD offers the longest rated lifetime at 12000 Hrs @ 105°C, compared to 7000 Hrs for the original UPW2C330MHD. This extended lifetime may reduce field failure rates in applications with continuous operation at elevated temperatures.
