Nichicon USV1C220MFD Equivalent & Substitute Parts

Part Overview

The Nichicon USV1C220MFD is a 22 µF, 16 V aluminum electrolytic capacitor in radial through-hole configuration, rated for 5000 hours at 105°C. This part carries an obsolete product status, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The USV series represents a legacy component line, and identifying compatible alternatives ensures design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution eligibility for the USV1C220MFD is determined by the following core parameters:

Capacitance Value: 22 µF (exact match required)
Voltage Rating: Minimum 16 V (equal or higher acceptable)
Tolerance: ±20% (standard tolerance match)
Mounting Type: Through Hole (mechanical compatibility)
Package Configuration: Radial, Can (footprint compatibility)
Lead Spacing: 0.079" (2.00mm) for direct PCB fit
Physical Dimensions: Compatible with 0.197" diameter and height constraints
Operating Temperature: -40°C ~ 105°C minimum range
RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Substitute parts are grouped into two categories: direct mechanical equivalents (same mounting and footprint) and functional alternatives (same electrical performance with different form factors or enhanced specifications).

Engineering Selection Recommendations

Direct Through-Hole Replacement (Preferred for Legacy Designs)

The UKL1C220MDDANA maintains identical lead spacing (0.079" / 2.00mm), physical diameter (0.197" / 5.00mm), and mounting type. However, its 1000-hour lifetime at 105°C is significantly reduced compared to the original 5000-hour rating. This part is marked "Not For New Designs" and should be used only when PCB layout constraints prohibit other alternatives.

Active Production Alternative (Through-Hole)

The RNS1C220MDS1 is an active Nichicon product with polymer technology, offering superior ripple current handling (190 mA @ 120 Hz vs. 44 mA for the original) and lower ESR (49 mOhm). The lead spacing increases to 0.098" (2.50mm) and diameter to 0.248" (6.30mm), requiring PCB layout verification. The 2000-hour lifetime at 105°C is lower than the original specification.

Higher Voltage Alternative (Through-Hole)

The UHE1H220MDD provides the same 5000-hour lifetime and identical lead spacing and diameter as the USV1C220MFD. The 50 V rating provides voltage margin for applications where supply voltage may exceed 16 V. Height increases to 0.433" (11.00mm), requiring clearance verification. Product status is obsolete.

Surface Mount Alternative (Active Production)

The UUL1C220MCL1GS is an active Nichicon product with 5000-hour lifetime matching the original specification. This part requires surface mount assembly and is suitable only for designs transitioning to SMD technology. Height is reduced to 0.240" (6.10mm), and ripple current capacity is lower (30 mA @ 120 Hz).

All substitute parts maintain ROHS3 compliance and the required operating temperature range of -40°C to 105°C.

Frequently Asked Questions (FAQ)

Q: Can the RNS1C220MDS1 be used as a direct PCB replacement for the USV1C220MFD?

A: No. The RNS1C220MDS1 has different lead spacing (0.098" vs. 0.079") and larger diameter (0.248" vs. 0.197"), requiring PCB layout modification. Verify hole spacing and component clearance before substitution.

Q: Why does the UHE1H220MDD have a higher voltage rating (50 V) than the original (16 V)?

A: Higher voltage ratings provide design margin and are electrically compatible in 16 V applications. The capacitor will function correctly at lower voltages. Verify that the increased height (0.433" vs. 0.315") does not violate PCB clearance constraints.

Q: Is the UUL1C220MCL1GS suitable for through-hole PCB designs?

A: No. The UUL1C220MCL1GS is a surface mount device (SMD) with different land pattern requirements. It is suitable only for designs using surface mount assembly processes.

Q: What is the impact of the RNS1C220MDS1's reduced lifetime (2000 Hrs vs. 5000 Hrs)?

A: The 2000-hour lifetime at 105°C is half the original specification. For applications requiring extended operational life at elevated temperatures, this reduction may impact reliability projections. Verify application duty cycle and thermal environment before selection.

Q: Can the UKL1C220MDDANA be used in new designs?

A: The UKL1C220MDDANA is marked "Not For New Designs." It is suitable only for legacy product maintenance and repair. For new designs, select the RNS1C220MDS1 or UUL1C220MCL1GS, both with active product status.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, meeting regulatory requirements for hazardous substance restrictions.
