Substitute Part Grouping Explanation

Substitution for the UPW2C2R2MED is determined by the following critical parameters:

Capacitance: Must be 2.2 µF (±20% tolerance acceptable)
Voltage Rating: Minimum 160 V; higher voltage ratings are acceptable as upgrades
Package / Case: Radial, can configuration required
Mounting Type: Through hole required
Lead Spacing: 0.098" (2.50mm) required for PCB compatibility
Operating Temperature Range: Must support -40°C ~ 105°C minimum
Lifetime: 2000 hours @ 105°C minimum
Polarization: Polar configuration required

Substitute parts are grouped into two categories:

Upgrade Substitutes: Parts with identical or superior electrical characteristics and higher voltage ratings (200 V or 250 V), maintaining full mechanical and thermal compatibility.

Parametric Equivalents: Parts with identical electrical and mechanical specifications, offering direct replacement capability.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent):

SEK2R2M160ST is the parametric equivalent to UPW2C2R2MED, offering identical electrical specifications and mechanical dimensions. This part is manufactured by Cornell Dubilier Electronics and maintains active product status, ensuring long-term availability. Both parts meet ROHS3 compliance and operate within the same temperature range. The SEK2R2M160ST is suitable for applications requiring exact specification matching.

For Upgraded Performance:

UPW2D2R2MED provides a voltage upgrade to 200 V while maintaining all other specifications of the original part. This Nichicon part is also obsolete but offers higher voltage margin for circuits operating near the 160 V rating.

SEK2R2M200ST and SEK2R2M250ST are active Cornell Dubilier Electronics products offering voltage upgrades to 200 V and 250 V respectively. Both parts maintain mechanical compatibility with the original design. SEK2R2M250ST provides the highest voltage margin and is recommended for applications requiring enhanced reliability or future design flexibility. Note that SEK2R2M200ST and SEK2R2M250ST have a maximum seated height of 0.453" (11.50mm), compared to 0.433" (11.00mm) for the original part; PCB layout clearance must be verified.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SEK2R2M160ST be used as a direct replacement for UPW2C2R2MED?

A: Yes. SEK2R2M160ST is a parametric equivalent with identical capacitance (2.2 µF), voltage rating (160 V), tolerance (±20%), thermal rating (2000 Hrs @ 105°C), and mechanical dimensions. Lead spacing, package type, and mounting configuration are identical. Direct substitution is possible without circuit modification.

Q: What is the difference between upgrade substitutes and parametric equivalents?

A: Parametric equivalents (SEK2R2M160ST) match all electrical and mechanical specifications of the original part. Upgrade substitutes (UPW2D2R2MED, SEK2R2M200ST, SEK2R2M250ST) provide higher voltage ratings while maintaining or exceeding other performance characteristics. Upgrade substitutes offer enhanced reliability margins but may require PCB layout verification due to dimensional changes.

Q: Are there height differences between substitute parts?

A: Yes. UPW2C2R2MED and SEK2R2M160ST have a maximum seated height of 0.433" (11.00mm). SEK2R2M200ST and SEK2R2M250ST have a maximum seated height of 0.453" (11.50mm). PCB clearance must be verified before substitution with the taller variants.

Q: Why is UPW2C2R2MED obsolete while SEK2R2M160ST is active?

A: Product status reflects manufacturer production and support decisions. Cornell Dubilier Electronics maintains active production of the SEK series, while Nichicon has discontinued the UPW series. For new designs and long-term availability, active products are preferred.

Q: Can SEK2R2M250ST be used in place of UPW2C2R2MED?

A: Yes. SEK2R2M250ST exceeds all electrical requirements of the original part with a 250 V rating (versus 160 V), identical capacitance and tolerance, and equivalent thermal performance. Mechanical compatibility is maintained with the exception of height (0.453" versus 0.433"). This part is recommended for applications requiring maximum voltage margin and long-term availability.

Q: What compliance certifications apply to these parts?

A: All listed parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
