USV1E220MFD Equivalent & Substitute Parts

Part Overview

The USV1E220MFD is a 22 µF, 25 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This through-hole component is rated for 5000 hours at 105°C and is classified as obsolete. Due to its obsolete status, equivalent substitute parts with maintained or enhanced electrical characteristics are necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitute parts for the USV1E220MFD are selected based on the following criteria:

Electrical Equivalence: Capacitance value (22 µF) and tolerance (±20%) must match exactly. Voltage rating must be equal to or greater than 25 V to ensure safe operation in the original circuit.

Mechanical Compatibility: Lead spacing (2.50mm) and package footprint must accommodate through-hole mounting on existing PCBs. Physical dimensions must not exceed the original envelope constraints.

Thermal & Reliability: Operating temperature range must span -40°C to 105°C minimum. Lifetime rating at 105°C should meet or exceed 5000 hours.

Compliance: RoHS3 compliance is required. REACH unaffected status must be maintained.

Two substitute categories are identified:

Through-Hole Radial Can (Direct Mechanical Replacement): ULD1J220MED maintains identical lead spacing and mounting type with enhanced voltage rating and lifetime.
Surface Mount Alternative (Functional Equivalent): UUL1E220MCL1GS provides electrical equivalence with identical voltage and capacitance but requires PCB redesign due to SMD mounting.

Engineering Selection Recommendations

For Direct Through-Hole Replacement: ULD1J220MED is the preferred substitute when PCB layout cannot be modified. It maintains identical lead spacing (2.50mm) and mounting footprint. The increased voltage rating (63 V vs. 25 V) provides design margin without affecting circuit operation. The doubled lifetime rating (10000 Hrs vs. 5000 Hrs at 105°C) improves long-term reliability. Both parts are ROHS3 compliant and REACH unaffected. The primary consideration is the increased height (12.50mm vs. 8.00mm), which must be verified against available PCB clearance.

For New Designs or PCB Redesign: UUL1E220MCL1GS is suitable when surface mount technology is acceptable. This part is active status, ensuring long-term availability. It maintains electrical equivalence (22 µF, 25 V, ±20%) with identical thermal ratings. The reduced height (6.10mm) provides space savings. Surface mount mounting requires PCB layout modification and updated assembly processes. ROHS3 compliance and REACH unaffected status are maintained.

Frequently Asked Questions (FAQ)

Q: Can ULD1J220MED be used as a direct replacement for USV1E220MFD without PCB modification?

A: Yes, mechanically and electrically. Both parts share identical lead spacing (2.50mm), diameter (6.30mm), and radial can package. The increased height (12.50mm vs. 8.00mm) must be verified against available vertical clearance on the PCB. The higher voltage rating (63 V) is compatible with 25 V circuit designs.

Q: What is the primary difference between ULD1J220MED and USV1E220MFD?

A: Voltage rating (63 V vs. 25 V), lifetime (10000 Hrs vs. 5000 Hrs at 105°C), and height (12.50mm vs. 8.00mm). Capacitance, tolerance, and lead spacing are identical.

Q: Can UUL1E220MCL1GS replace USV1E220MFD without PCB redesign?

A: No. UUL1E220MCL1GS is a surface mount component, while USV1E220MFD is through-hole. PCB layout and assembly process changes are required. This substitution is suitable only for new designs or complete PCB redesigns.

Q: Are all three parts RoHS3 compliant?

A: Yes. USV1E220MFD, ULD1J220MED, and UUL1E220MCL1GS are all ROHS3 compliant and REACH unaffected.

Q: Which substitute has the longest operational lifetime?

A: ULD1J220MED is rated for 10000 hours at 105°C, compared to 5000 hours for both USV1E220MFD and UUL1E220MCL1GS.

Q: Is UUL1E220MCL1GS available for production use?

A: Yes. UUL1E220MCL1GS has active product status, ensuring ongoing availability. USV1E220MFD and ULD1J220MED are both obsolete.
