Substitute Part Grouping Explanation

Substitution eligibility for the UPW2E220MHD1TO is determined by strict equivalence across the following parameters:

• Capacitance value: 22 µF (exact match required)
• Voltage rating: 250 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package configuration: Radial, Can (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.197" (5.00 mm) (exact match required)
• Operating temperature range: -40°C to 105°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The Würth Elektronik part 860241178002 meets all mandatory substitution criteria. While physical dimensions and ripple current ratings differ, these variations remain within acceptable tolerance for through-hole radial capacitor substitution where the core electrical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 860241178002 is a direct electrical equivalent to the UPW2E220MHD1TO. Both components satisfy identical core specifications: 22 µF capacitance, 250 V voltage rating, ±20% tolerance, polar configuration, and through-hole radial mounting with 5.00 mm lead spacing.

The substitute part carries Active product status, whereas the original part is designated Not For New Designs. This status difference reflects Nichicon's product lifecycle management and does not affect functional compatibility in existing applications.

Both parts maintain ROHS3 compliance and operate across the identical temperature range of -40°C to 105°C. The Würth Elektronik part provides extended operational lifetime (10000 hours at 105°C versus 7000 hours), representing an enhancement over the original specification.

Physical dimensions show minor variation: the Würth part measures 0.512" diameter (13.00 mm) and 0.846" height (21.50 mm) compared to the Nichicon part at 0.492" diameter (12.50 mm) and 1.063" height (27.00 mm). These dimensional differences remain within acceptable tolerance for through-hole PCB mounting applications where lead spacing is the controlling constraint.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 860241178002 be used as a direct replacement for the UPW2E220MHD1TO?

A: Yes. Both parts share identical electrical specifications: 22 µF capacitance, 250 V voltage rating, ±20% tolerance, polar configuration, and 5.00 mm lead spacing. Through-hole mounting compatibility is maintained.

Q: What is the significance of the "Not For New Designs" status on the original part?

A: This designation indicates the UPW2E220MHD1TO has been superseded in Nichicon's active product line. It does not affect functionality in existing applications but signals that the manufacturer recommends using current-generation alternatives for new designs.

Q: Do the physical dimension differences between these parts affect PCB compatibility?

A: Lead spacing remains identical at 5.00 mm, which is the primary constraint for through-hole PCB mounting. Variations in can diameter and height do not impact electrical function or board-level compatibility in standard applications.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the UPW2E220MHD1TO and 860241178002 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the advantage of the extended lifetime specification on the substitute part?

A: The Würth Elektronik part provides 10000 hours operational lifetime at 105°C compared to 7000 hours for the original part. This extended rating provides additional margin in applications subject to sustained elevated temperature operation.
