Equivalent & Substitute Parts for UTT1C221MPD1TD

Part Overview

The UTT1C221MPD1TD is a 220 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 5000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The product status is obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UTT1C221MPD1TD is determined by the following critical parameters:

• Capacitance Value: 220 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: Minimum 16 V (equal or higher acceptable)
• Package Type: Radial, Can through-hole configuration
• Physical Dimensions: Compatible with 0.315" diameter and lead spacing of 0.138" (4.60mm)
• Operating Temperature Range: -40°C ~ 105°C (minimum requirement)
• Compliance: ROHS3 compliant

The substitute part 25YXH220MEFCTA8X11.5 (Rubycon YXH series) meets all substitution criteria with a higher voltage rating (25 V) and improved lifetime specification (7000 Hrs @ 105°C), providing enhanced reliability margins for the same capacitance and tolerance values.

Parameter Comparison

Engineering Selection Recommendations

The 25YXH220MEFCTA8X11.5 from Rubycon is a direct functional substitute for the obsolete UTT1C221MPD1TD. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The substitute part provides improved specifications: higher voltage rating (25 V vs. 16 V) and extended lifetime (7000 Hrs vs. 5000 Hrs at 105°C). These enhancements offer increased design margin and reliability.

Physical compatibility requires verification: the substitute has a taller seated height (0.512" vs. 0.413") and wider lead spacing (0.197" vs. 0.138"). PCB layout and mechanical clearance must be confirmed before implementation.

Frequently Asked Questions (FAQ)

Q: Can the 25YXH220MEFCTA8X11.5 be used as a direct replacement for UTT1C221MPD1TD?

A: Electrically, yes. Both components have identical capacitance (220 µF) and tolerance (±20%), with the substitute offering higher voltage rating and longer lifetime. Physical dimensions differ; lead spacing and height must be verified against PCB design.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (25 V vs. 16 V), lifetime specification (7000 Hrs vs. 5000 Hrs @ 105°C), lead spacing (0.197" vs. 0.138"), and seated height (0.512" vs. 0.413"). Capacitance, tolerance, and operating temperature range are identical.

Q: Are both parts compliant with current regulations?

A: Yes. Both the UTT1C221MPD1TD and 25YXH220MEFCTA8X11.5 are ROHS3 compliant and REACH unaffected.

Q: What should be considered when selecting between these parts?

A: Verify PCB layout compatibility with the substitute's lead spacing and height. Confirm that the higher voltage rating (25 V) is acceptable for the application. Assess availability; the Nichicon part is obsolete while the Rubycon part is Last Time Buy status.

Q: Can the substitute be used in applications originally designed for 16 V operation?

A: Yes. The 25 V rated substitute is suitable for 16 V applications, as voltage rating indicates maximum operating voltage, not a requirement.
