Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPJ2F470MHD is determined by the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Capacitance value must equal or exceed 47 µF
• Voltage rating must be equal to or greater than 315 V
• Tolerance must be ±20% or tighter
• Polarization must remain polar

Mechanical Compatibility Criteria:

• Lead spacing must match 0.295" (7.50mm)
• Package type must be radial, can configuration
• Mounting type must be through hole
• Physical dimensions must accommodate existing PCB footprints

Regulatory & Compliance Criteria:

• RoHS3 compliance required
• REACH unaffected status maintained

The substitute part UCS2W330MHD meets these criteria with enhanced performance specifications in voltage rating and operational lifetime.

Parameter Comparison

Engineering Selection Recommendations

The UCS2W330MHD is an active product from Nichicon and serves as the direct substitute for the obsolete UPJ2F470MHD. Selection of this substitute is supported by the following factors:

Voltage Margin: The UCS2W330MHD provides 450 V rating versus the original 315 V requirement, delivering a 43% voltage safety margin for the application.

Operational Lifetime: The substitute offers 10000 Hrs @ 105°C compared to 5000 Hrs, doubling the thermal lifetime specification.

Physical Compatibility: Both components share identical lead spacing of 0.295" (7.50mm) and through-hole mounting configuration. The substitute features a smaller diameter (0.630" vs 0.709") and reduced height (1.043" vs 1.457"), allowing direct PCB footprint compatibility with potential space savings.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring continued regulatory alignment.

Capacitance Consideration: The UCS2W330MHD provides 33 µF versus the original 47 µF. Circuit design review is required to confirm that 33 µF capacitance meets functional requirements for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the UCS2W330MHD directly replace the UPJ2F470MHD without circuit modification?

A: Direct replacement requires verification that 33 µF capacitance is functionally equivalent to the original 47 µF specification. The 30% capacitance reduction may affect circuit performance depending on application requirements. Lead spacing and mounting type are identical, enabling physical PCB compatibility.

Q: What is the voltage margin provided by the substitute part?

A: The UCS2W330MHD operates at 450 V versus the original 315 V requirement, providing a 135 V (43%) voltage safety margin. This enhanced rating supports higher transient voltage conditions and improves component reliability.

Q: Are there physical dimension constraints with the substitute part?

A: The UCS2W330MHD is physically smaller than the UPJ2F470MHD. The substitute measures 0.630" diameter and 1.043" height compared to 0.709" diameter and 1.457" height. This reduction in size allows installation in the original footprint with potential clearance improvements.

Q: What is the operational lifetime difference between these components?

A: The UCS2W330MHD provides 10000 Hrs @ 105°C thermal lifetime, compared to 5000 Hrs for the UPJ2F470MHD. This doubling of operational life extends component reliability and reduces maintenance intervals.

Q: Are both components RoHS compliant?

A: Both the UPJ2F470MHD and UCS2W330MHD are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment for current manufacturing and distribution requirements.

Q: What is the operating temperature range difference?

A: The UPJ2F470MHD operates from -40°C to 105°C, while the UCS2W330MHD operates from -25°C to 105°C. The substitute has a narrower low-temperature range by 15°C. Applications requiring operation below -25°C require alternative component selection.
