Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UCS2D100MPD are identified based on the following criteria:

Capacitance value must match exactly at 10 µF. Tolerance must remain ±20%. Polarization must be Polar. Mounting type must be Through Hole with Radial, Can package configuration. Lead spacing must be 0.197" (5.00mm). Physical dimensions (diameter 0.394", height within acceptable mechanical envelope) must accommodate the same PCB footprint. Operating temperature range must span -40°C ~ 105°C minimum. RoHS3 compliance is required. Voltage rating may exceed the original specification, provided all other parameters remain compatible.

Parameter Comparison

Engineering Selection Recommendations

The 450BXW10MEFR10X16 (Rubycon BXW series) qualifies as a direct substitute for the UCS2D100MPD based on matching electrical specifications and mechanical compatibility. Both components are Active product status and ROHS3 compliant. The substitute part provides a higher voltage rating (450 V versus 200 V), which does not compromise circuit function in applications designed for 200 V operation. The substitute offers extended lifetime (10000 Hrs @ 105°C versus 8000 Hrs @ 105°C), representing improved reliability. Physical dimensions remain compatible with identical lead spacing and diameter; height difference of 0.020" (0.50mm) falls within standard PCB assembly tolerances for through-hole radial components.

Frequently Asked Questions (FAQ)

Q: Can the 450BXW10MEFR10X16 replace the UCS2D100MPD in all applications?

A: Yes, provided the circuit is designed for 200 V operation. The substitute part's higher voltage rating (450 V) does not affect performance in lower voltage circuits. All electrical parameters (capacitance, tolerance, temperature range) and mechanical specifications (lead spacing, package type, mounting configuration) are compatible.

Q: What is the significance of the voltage rating difference?

A: The substitute part operates at a higher voltage specification (450 V rated versus 200 V rated). This provides additional safety margin in the application. The component will function correctly in circuits designed for the original 200 V specification.

Q: Are the physical dimensions identical?

A: Diameter and lead spacing are identical (0.394" diameter, 0.197" lead spacing). Height differs by 0.020" (0.50mm), with the substitute measuring 0.709" versus 0.689" for the original. This difference is within standard through-hole assembly tolerances and does not affect PCB footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the UCS2D100MPD and 450BXW10MEFR10X16 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8532.22.0020.

Q: What is the difference in ripple current ratings?

A: The original part specifies 160 mA @ 120 Hz (low frequency) and 320 mA @ 100 kHz (high frequency). The substitute specifies 130 mA @ 120 Hz and 325 mA @ 100 kHz. These differences reflect manufacturer design variations and do not affect substitution compatibility for general purpose applications.
