Substitute Part Grouping Explanation

Substitution eligibility for the UPB2E220MHD1TO is determined by the following critical parameters:

Primary Compatibility Criteria:

Capacitance value: 22 µF (exact match required)
Tolerance: ±20% (exact match required)
Lead spacing: 0.197" (5.00 mm) (exact match required)
Case diameter: 0.492" (12.50 mm) (exact match required)
Height: 0.846" (21.50 mm) (exact match required)
Mounting type: Through Hole (exact match required)
Package type: Radial, Can (exact match required)

Secondary Compatibility Criteria (Upgrade Allowable):

Voltage rating: 250 V or higher (higher ratings provide design margin)
Operating temperature range: -25°C to 105°C or wider (wider ranges provide flexibility)
Lifetime @ 105°C: 5000 Hrs or longer (longer lifetimes improve reliability)
Ripple current ratings: Equal to or greater than specified values

Substitute parts UCY2V220MHD3 and UCY2V220MHD3TO meet all primary criteria with enhanced voltage rating (350 V), extended lifetime (12000 Hrs @ 105°C), and wider operating temperature range (-40°C to 105°C). Similar part UCS2E220MPD1TD maintains voltage rating equivalence with improved lifetime and temperature range, though with reduced case diameter (0.394" vs 0.492").

Engineering Selection Recommendations

For Direct Replacement (Preferred): UCY2V220MHD3 and UCY2V220MHD3TO are the primary substitutes. Both maintain identical physical dimensions and lead spacing while providing enhanced electrical performance. The 350 V rating offers increased design margin over the original 250 V specification. Extended lifetime (12000 Hrs vs 5000 Hrs @ 105°C) and wider operating temperature range (-40°C to -25°C) improve system reliability. Both parts are ROHS3 compliant and carry active product status, ensuring long-term availability. UCY2V220MHD3TO in Cut Tape packaging offers the highest inventory level (1601 units) for immediate procurement.

For Space-Constrained Applications: UCS2E220MPD1TD maintains the 250 V voltage rating with reduced case diameter (0.394" vs 0.492"), suitable for designs where radial footprint must be minimized. This part provides 8000 Hrs lifetime at 105°C and ROHS3 compliance. However, ripple current ratings are reduced (250 mA @ 120 Hz, 500 mA @ 100 kHz), requiring verification against circuit requirements. Inventory availability is highest at 3200 units.

Compliance Considerations: All substitute parts are ROHS3 compliant, meeting modern environmental and regulatory standards. The original UPB2E220MHD1TO does not specify RoHS status. Substitutes carry REACH Affected or REACH Unaffected designations as applicable.

Frequently Asked Questions (FAQ)

Q: Can UCY2V220MHD3 and UCY2V220MHD3TO be used interchangeably with UPB2E220MHD1TO?

A: Yes. Both parts are direct physical and electrical substitutes. They share identical capacitance (22 µF), tolerance (±20%), lead spacing (5.00 mm), case diameter (12.50 mm), and height (21.50 mm). The 350 V rating is compatible with 250 V circuit requirements, providing additional design margin. The only difference is packaging: UCY2V220MHD3 is supplied in Bulk, while UCY2V220MHD3TO is supplied in Cut Tape (CT).

Q: What is the difference between UCY2V220MHD3 and UCY2V220MHD3TO?

A: Both parts are electrically and physically identical. The difference is packaging format: UCY2V220MHD3 is supplied in Bulk packaging, while UCY2V220MHD3TO is supplied in Cut Tape (CT) format. Selection depends on assembly process requirements and inventory management preferences.

Q: Why does UCS2E220MPD1TD have a smaller case diameter?

A: UCS2E220MPD1TD uses a 0.394" (10.00 mm) case diameter compared to 0.492" (12.50 mm) for the main part. This represents a different physical design within the same capacitance and voltage class. While it maintains lead spacing and height compatibility, the reduced diameter may affect PCB layout. Verify ripple current ratings (250 mA @ 120 Hz, 500 mA @ 100 kHz) against circuit specifications before selection.

Q: Is the higher voltage rating (350 V) of UCY2V220MHD3 and UCY2V220MHD3TO a concern?

A: No. Higher voltage ratings are compatible with lower voltage circuit requirements. The 350 V rating provides additional design margin and stress relief, improving component longevity and reliability in the 250 V application.

Q: What is the significance of the extended lifetime rating?

A: UCY2V220MHD3 and UCY2V220MHD3TO offer 12000 Hrs @ 105°C compared to 5000 Hrs for the original part. This 2.4x improvement in rated lifetime indicates superior capacitor construction and materials, resulting in reduced failure rates and extended system operational life.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. UCY2V220MHD3, UCY2V220MHD3TO, and UCS2E220MPD1TD are all ROHS3 compliant. The original UPB2E220MHD1TO does not specify RoHS status. Modern designs should prioritize ROHS3 compliant substitutes.

Q: Which substitute offers the best inventory availability?

A: UCS2E220MPD1TD has the highest inventory at 3200 units. UCY2V220MHD3TO has 1601 units, and UCY2V220MHD3 has 1070 units. For immediate procurement, UCS2E220MPD1TD provides the largest available stock, though case diameter differences must be verified against PCB layout constraints.
