Substitute Part Grouping Explanation

Substitution for the UPB1C222MHD1TO is determined by strict equivalence across the following critical parameters:

Capacitance: 2200 µF (exact match required)
Voltage Rating: 16 V minimum (higher ratings acceptable as upgrades)
Tolerance: ±20% (standard for this category)
Package: Radial, Can with Through Hole mounting
Lead Spacing: 0.197" (5.00 mm)
Diameter: 0.492" (12.50 mm) or compatible mechanical envelope
Polarization: Polar (mandatory)
Operating Temperature: -40°C to 105°C minimum

Substitutes are grouped into two categories: direct equivalents matching all mechanical and electrical parameters, and upgrades offering improved lifetime or voltage rating while maintaining physical compatibility.

Engineering Selection Recommendations

Direct Equivalents (Mechanical and Electrical Match):

UPW1C222MHD1TO and EEU-FM1C222B maintain the original 7000-hour lifetime specification while offering extended temperature range (-55°C minimum for UPW1C222MHD1TO) and ROHS3 compliance. Both are suitable for direct replacement where the original height tolerance of 1.043" is acceptable with the slight increase to 1.063".

Upgraded Alternatives (Enhanced Lifetime):

UHE1C222MHD1TO, EEU-EB1C222B, EEU-EB1C222, and 860040378015 provide 10000-hour lifetime at 105°C, extending component reliability. These parts are classified as active or not for new designs, with full ROHS3 compliance. The Würth Elektronik part (860040378015) features a slightly larger diameter (0.512" vs 0.492") but maintains compatible height and lead spacing.

Voltage Upgrade Option:

EEU-FS1E222B offers a 25 V rating with identical physical dimensions and 10000-hour lifetime. This part is suitable for applications requiring higher voltage margin while maintaining backward compatibility with the original PCB layout.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V rated capacitor in place of the 16 V UPB1C222MHD1TO?

A: Yes. EEU-FS1E222B is rated for 25 V and maintains identical capacitance, tolerance, physical dimensions, and lead spacing. Higher voltage ratings provide additional safety margin in the circuit without affecting performance at the original 16 V operating point.

Q: What is the difference between parts marked "Obsolete" and "Not For New Designs"?

A: UPB1C222MHD1TO is obsolete and no longer manufactured. UPW1C222MHD1TO and UHE1C222MHD1TO are not recommended for new designs but remain available. Active parts (EEU-EB1C222B, EEU-FM1C222B, 860040378015, EEU-FS1E222B) are current production items suitable for new applications.

Q: Does the height difference between 1.043" and 1.063" affect PCB compatibility?

A: The 0.020" (0.50 mm) height increase is within typical PCB design tolerances for through-hole radial capacitors. Verify clearance in your specific layout, particularly if space is constrained above the component.

Q: Which substitute offers the best reliability?

A: Parts with 10000-hour lifetime ratings (UHE1C222MHD1TO, EEU-EB1C222B, EEU-EB1C222, 860040378015, EEU-FS1E222B) provide extended operational life compared to the original 7000-hour specification.

Q: Are all substitutes ROHS3 compliant?

A: UPB1C222MHD1TO is REACH Unaffected. All substitute parts listed are ROHS3 Compliant, meeting current environmental and regulatory requirements for new production.

Q: What packaging options are available?

A: Substitutes are supplied in Cut Tape (CT), Tape & Box (TB), or Bulk packaging. Verify packaging requirements for your procurement and assembly process.
