Substitute Part Grouping Explanation

The Rubycon 35NXA220MEFC10X20 qualifies as a substitute for the UES1C221MPM based on the following alignment of critical parameters:

• Capacitance Match: Both parts are 220 µF
• Tolerance Match: Both maintain ±20% tolerance
• Polarization Match: Both are bi-polar configurations
• Lead Spacing Match: Both use 0.197" (5.00mm) lead spacing
• Case Diameter Match: Both use 0.394" (10.00mm) diameter
• Mounting Type Match: Both are through-hole radial components
• Package Type Match: Both are radial, can configurations
• Compliance Match: Both are ROHS3 compliant

The 35NXA220MEFC10X20 provides enhanced electrical performance with a higher voltage rating (35 V vs. 16 V) and extended operating temperature range (-55°C ~ 105°C vs. -40°C ~ 85°C), making it suitable for applications requiring the original part's specifications while offering improved reliability margins.

Parameter Comparison

Engineering Selection Recommendations

The 35NXA220MEFC10X20 is suitable as a direct substitute for the UES1C221MPM in applications requiring the original specifications. Both components meet ROHS3 compliance requirements. The Rubycon part carries an "Active" product status, ensuring continued availability and supply chain stability compared to the Nichicon part's "Not For New Designs" designation. The marginal height difference (0.020" / 0.50mm) falls within typical PCB layout tolerances for through-hole radial components. The higher voltage rating and extended temperature range of the substitute provide additional operational margin without compromising form factor compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 35NXA220MEFC10X20 be used as a direct replacement for the UES1C221MPM?

A: Yes. Both components share identical capacitance (220 µF), tolerance (±20%), lead spacing (5.00mm), case diameter (10.00mm), and mounting configuration (through-hole radial). The substitute's higher voltage rating (35 V) and extended temperature range do not prevent direct substitution in circuits designed for the original 16 V, 85°C specification.

Q: What is the height difference between these parts?

A: The UES1C221MPM has a maximum seated height of 0.846" (21.50mm), while the 35NXA220MEFC10X20 measures 0.866" (22.00mm). The 0.020" (0.50mm) difference is negligible for standard PCB layouts and does not affect mechanical clearance in typical applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the UES1C221MPM and 35NXA220MEFC10X20 are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Why does the substitute have a higher voltage rating?

A: The 35NXA220MEFC10X20 is rated for 35 V compared to the original part's 16 V rating. This higher voltage specification does not affect compatibility in 16 V applications and provides additional safety margin against voltage transients or overvoltage conditions.

Q: What is the difference in operating temperature ranges?

A: The UES1C221MPM operates from -40°C to 85°C, while the 35NXA220MEFC10X20 operates from -55°C to 105°C. The substitute's extended range accommodates applications in more extreme thermal environments without performance degradation.
