Substitute Part Grouping Explanation

Substitute parts for the UPW2C2R2MEH are categorized based on the following allowed electrical and mechanical parameters:

Direct Equivalent (Same Voltage Rating):

Capacitance: 2.2 µF
Tolerance: ±20%
Voltage: 160 V
Lifetime: 2000 Hrs @ 105°C
Lead Spacing: 0.098" (2.50mm)
Package: Radial, Can
Mounting: Through Hole

Upgrade Substitutes (Higher Voltage Rating):

Capacitance: 2.2 µF
Tolerance: ±20%
Voltage: 200 V or 250 V
Lifetime: 2000 Hrs @ 105°C
Lead Spacing: 0.098" (2.50mm)
Package: Radial, Can
Mounting: Through Hole

Higher voltage-rated parts are functionally compatible in circuits designed for 160 V operation, as they provide additional voltage margin while maintaining identical capacitance, tolerance, and physical footprint.

Engineering Selection Recommendations

Direct Replacement (Same Electrical Performance): UPW2C2R2MED offers identical electrical specifications to the UPW2C2R2MEH with ROHS3 compliance. This part is the preferred direct substitute for applications requiring no design modification.

SEK2R2M160ST provides parametric equivalence with identical voltage and capacitance ratings. This part carries active product status and ROHS3 compliance, making it suitable for long-term procurement stability.

Upgrade Substitutes (Enhanced Voltage Margin): UPW2D2R2MED and SEK2R2M200ST provide 200 V ratings, offering 25% additional voltage headroom over the original 160 V specification. Both parts maintain identical capacitance, tolerance, and thermal characteristics.

SEK2R2M250ST provides 250 V rating, offering 56% additional voltage margin. This part is suitable for applications requiring maximum voltage safety margin while maintaining the same capacitive value and thermal performance.

Product Status Consideration: SEK2R2M160ST, SEK2R2M200ST, and SEK2R2M250ST carry active product status, ensuring long-term availability and supply chain continuity compared to obsolete Nichicon alternatives.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated substitute in place of the UPW2C2R2MEH? A: Yes. Higher voltage-rated parts (200 V or 250 V) are functionally compatible in circuits designed for 160 V operation. The capacitance, tolerance, and physical footprint remain identical, and higher voltage ratings provide additional circuit margin.

Q: What is the difference between UPW2C2R2MED and SEK2R2M160ST? A: Both parts are parametric equivalents with identical electrical specifications (2.2 µF, ±20%, 160 V, 2000 Hrs @ 105°C). UPW2C2R2MED is manufactured by Nichicon; SEK2R2M160ST is manufactured by Cornell Dubilier Electronics. SEK2R2M160ST carries active product status, while UPW2C2R2MED is obsolete.

Q: Are there physical differences between substitute parts? A: SEK2R2M200ST and SEK2R2M250ST have a maximum seated height of 0.453" (11.50mm) compared to 0.433" (11.00mm) for the original part and other substitutes. Verify PCB layout clearance before selection.

Q: Which substitute offers the best long-term availability? A: SEK2R2M160ST, SEK2R2M200ST, and SEK2R2M250ST all carry active product status from Cornell Dubilier Electronics, ensuring ongoing availability and supply chain support.

Q: Are all substitutes RoHS compliant? A: The original UPW2C2R2MEH is RoHS non-compliant. All listed substitutes (UPW2C2R2MED, UPW2D2R2MED, SEK2R2M160ST, SEK2R2M200ST, SEK2R2M250ST) are ROHS3 compliant.
