The substitute parts identified maintain these core electrical and mechanical parameters, ensuring direct compatibility in circuit applications designed for the UCS2V101MHD.

Parameter Comparison

Engineering Selection Recommendations

UCY2V101MHD3 (Direct Substitute - Nichicon)

The UCY2V101MHD3 is a direct equivalent from the same manufacturer. It maintains identical electrical specifications (100 µF, 350 V, ±20% tolerance) and mechanical compatibility. The UCY2V101MHD3 offers extended lifetime (12000 Hrs @ 105°C versus 10000 Hrs), providing improved reliability in the same form factor. Both parts are Active status and ROHS3 compliant. This substitute is suitable for direct replacement without circuit redesign.

400BXW100MEFR18X25 (Upgrade Substitute - Rubycon)

The Rubycon 400BXW100MEFR18X25 is classified as an upgrade substitute due to its higher voltage rating (400 V versus 350 V). This part maintains the same capacitance (100 µF), tolerance (±20%), and operating temperature range. The 400 V rating provides additional voltage margin in applications where the circuit design permits higher-rated components. Physical dimensions are compatible with a maximum seated height of 1.063" (27.00mm), which is within acceptable tolerance for standard PCB layouts. The part is Active status and ROHS3 compliant. Selection of this upgrade is appropriate when enhanced voltage headroom is beneficial to circuit performance or reliability.

Frequently Asked Questions (FAQ)

Q: Can the UCY2V101MHD3 be used as a direct replacement for the UCS2V101MHD?

A: Yes. The UCY2V101MHD3 maintains identical capacitance (100 µF), voltage rating (350 V), tolerance (±20%), and mechanical dimensions. Both are Nichicon products with Active status and ROHS3 compliance. The UCY2V101MHD3 offers extended lifetime specification (12000 Hrs @ 105°C), making it a compatible direct substitute.

Q: What is the difference between the UCS2V101MHD and the 400BXW100MEFR18X25?

A: The primary difference is the voltage rating. The UCS2V101MHD is rated at 350 V, while the 400BXW100MEFR18X25 is rated at 400 V. Both maintain 100 µF capacitance and ±20% tolerance. The 400BXW100MEFR18X25 is manufactured by Rubycon and provides higher voltage margin. Physical dimensions are compatible, with the Rubycon part having a maximum seated height of 1.063" (27.00mm) compared to 1.043" (26.50mm) for the Nichicon part.

Q: Are there any compliance differences between these substitute parts?

A: All three parts (UCS2V101MHD, UCY2V101MHD3, and 400BXW100MEFR18X25) are ROHS3 compliant. The UCS2V101MHD and 400BXW100MEFR18X25 are REACH Unaffected. The UCY2V101MHD3 is REACH Affected. All parts carry EAR99 ECCN classification and 8532.22.0020 HTSUS code.

Q: Can the 400BXW100MEFR18X25 be used in place of the UCS2V101MHD in all applications?

A: The 400BXW100MEFR18X25 is mechanically and electrically compatible for applications designed for 350 V or lower. The higher 400 V rating does not create incompatibility. However, verify that the maximum seated height of 1.063" (27.00mm) accommodates your PCB layout, as it is 0.020" taller than the UCS2V101MHD specification.

Q: What are the ripple current specifications for these parts?

A: All three parts support similar ripple current performance. At 120 Hz, ripple currents range from 710 mA to 790 mA. At 100 kHz, ripple currents range from 1.575 A to 1.598 A. These specifications are within acceptable variance for general-purpose applications.
