Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCS2D100MPD1TD is determined by the following critical parameters:

• Capacitance Value: Must remain 10 µF (no tolerance deviation acceptable for direct substitution)
• Tolerance: Must be ±20% or tighter
• Polarization: Must be Polar (same as original)
• Lead Spacing: Must be 0.197" (5.00mm) for PCB compatibility
• Physical Dimensions: Must match 0.394" Dia × 0.689" Height (Max) for mechanical fit
• Mounting Type: Must be Through Hole Radial configuration
• Operating Temperature Range: Must support -40°C ~ 105°C minimum
• Voltage Rating: May be equal to or higher than 200 V (uprating is acceptable)
• Compliance: Must maintain ROHS3 compliance

The UCY2G100MPD1TD qualifies as a substitute based on matching all critical parameters while providing enhanced voltage rating (400 V) and extended lifetime (10000 Hrs @ 105°C).

Parameter Comparison

Engineering Selection Recommendations

The UCY2G100MPD1TD is a direct substitute for the UCS2D100MPD1TD in applications where the circuit design permits voltage uprating. Both components maintain Active product status and ROHS3 compliance. The substitute part provides increased voltage margin (400 V vs. 200 V) and extended operational lifetime (10000 Hrs vs. 8000 Hrs at 105°C), making it suitable for applications requiring enhanced reliability or operating in sustained high-temperature conditions. Physical footprint compatibility is confirmed across all mechanical dimensions and lead spacing specifications.

Frequently Asked Questions (FAQ)

Q: Can UCY2G100MPD1TD replace UCS2D100MPD1TD in any circuit?

A: The UCY2G100MPD1TD is mechanically and electrically compatible as a direct substitute. The higher voltage rating (400 V) does not degrade performance in circuits designed for 200 V operation. Verify that your circuit design does not depend on the specific ESR or ripple current characteristics of the original part.

Q: Are there physical dimension differences between these parts?

A: No. Both parts share identical lead spacing (0.197" / 5.00mm), diameter (0.394" / 10.00mm), and maximum seated height (0.689" / 17.50mm). PCB layout modifications are not required.

Q: What is the difference in ripple current handling?

A: The UCS2D100MPD1TD specifies 160 mA @ 120 Hz and 320 mA @ 100 kHz. The UCY2G100MPD1TD specifies 150 mA @ 120 Hz and 300 mA @ 100 kHz. Applications with ripple current demands exceeding 150 mA @ 120 Hz should retain the original part specification.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. The UCY2G100MPD1TD is REACH Affected, while the UCS2D100MPD1TD is REACH Unaffected. Verify REACH compliance requirements for your end application.

Q: Is the ±20% tolerance maintained in the substitute?

A: Yes. Both parts maintain ±20% capacitance tolerance, ensuring equivalent performance in tolerance-sensitive circuit designs.
