Operating Temperature Range: -55°C ~ 150°C (identical)
Lifetime @ Temperature: 1000 Hrs @ 150°C (identical)
Polarization: Polar (identical)
Mounting Type: Through Hole (identical)
Package / Case: Radial, Can (identical)
Lead Spacing: 0.197" (5.00mm) (identical)
Physical Dimensions: 0.492" Dia × 1.043" Height (identical)
Series: UBX (identical)
Manufacturer: Nichicon (identical)
RoHS Status: ROHS3 Compliant (identical)

Differing Parameter (Upgrade Characteristic):

Voltage - Rated: 35 V (main part) vs. 63 V (substitute)

The substitute part operates at a higher voltage rating, making it suitable for applications where the original 35 V specification can accommodate a higher-rated component without circuit modification.

Engineering Selection Recommendations

Both the UBX1V221MHL1TO and UBX1J221MHL1TO are active production components with full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance for automotive applications. The substitute part UBX1J221MHL1TO provides identical mechanical and thermal characteristics with an upgraded voltage rating of 63 V compared to the 35 V specification of the main part. This voltage upgrade allows the substitute to function in circuits designed for the original 35 V component without requiring PCB modifications or design changes. The identical physical footprint, lead spacing, and mounting configuration ensure direct board-level compatibility. Selection between these parts depends on circuit voltage requirements and component availability.

Frequently Asked Questions (FAQ)

Q: Can the UBX1J221MHL1TO (63 V) be used as a direct replacement for the UBX1V221MHL1TO (35 V)?

A: Yes. The substitute part maintains identical capacitance (220 µF), tolerance (±20%), physical dimensions, lead spacing, and mounting configuration. The higher voltage rating does not prevent operation in a 35 V circuit; it provides additional voltage margin. No PCB modifications are required.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. Both parts share identical physical dimensions (0.492" diameter, 1.043" maximum height), lead spacing (0.197" / 5.00mm), and radial can package configuration. They are mechanically interchangeable on the PCB.

Q: Do both parts meet the same automotive and compliance standards?

A: Yes. Both components are rated for automotive applications, maintain 1000 hours lifetime at 150°C, operate across -55°C to 150°C, and hold ROHS3 compliance with REACH unaffected status.

Q: What is the difference in ripple current handling between these parts?

A: The substitute part UBX1J221MHL1TO has higher ripple current ratings: 520 mA at 120 Hz (versus 300 mA) and 1.04 A at 100 kHz (versus 600 mA). This increased ripple current capacity is a characteristic of the higher voltage rating but does not affect substitution compatibility.

Q: Are both parts available in the same packaging format?

A: Yes. Both components are supplied in Cut Tape (CT) packaging with identical lead spacing and through-hole mounting configuration.
