Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPB2V151MHD is determined by the following critical parameters:

• Capacitance Value: Must remain 150 µF to maintain circuit function
• Tolerance: ±20% tolerance is acceptable for general-purpose applications
• Voltage Rating: Substitute must meet or exceed 350 V rated voltage
• Physical Dimensions: Lead spacing, diameter, and height must match for PCB compatibility
• Mounting Type: Through-hole radial configuration required
• Thermal Characteristics: Operating temperature range and lifetime rating must support application requirements

The UPT2G151MHD qualifies as a direct substitute based on matching capacitance, tolerance, physical dimensions, lead spacing, mounting type, and thermal operating range. The higher voltage rating (400 V) provides additional design margin while maintaining identical mechanical compatibility.

Engineering Selection Recommendations

The UPT2G151MHD is the qualified substitute for the obsolete UPB2V151MHD. Selection is based on the following factors:

• Product Status: The UPT2G151MHD is active and currently available, whereas the UPB2V151MHD is obsolete
• Electrical Compatibility: Identical capacitance and tolerance values ensure circuit performance equivalence
• Voltage Margin: The 400 V rating of the substitute exceeds the 350 V requirement, providing additional design margin
• Mechanical Compatibility: Identical physical dimensions, lead spacing, and mounting configuration ensure direct PCB compatibility without layout modifications
• Thermal Performance: Matching operating temperature range and lifetime rating maintain reliability characteristics
• Compliance: The UPT2G151MHD carries RoHS3 compliance certification, meeting modern regulatory requirements

Frequently Asked Questions (FAQ)

Q: Can the UPT2G151MHD be used as a direct replacement for the UPB2V151MHD?

A: Yes. The UPT2G151MHD is a direct substitute. Both parts share identical capacitance (150 µF), tolerance (±20%), physical dimensions, lead spacing, and mounting configuration. No PCB modifications are required.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The UPT2G151MHD is rated for 400 V compared to the 350 V rating of the UPB2V151MHD. This higher voltage rating provides additional design margin and does not negatively impact circuit operation when the original design calls for 350 V.

Q: Are there any thermal performance differences between these parts?

A: Both parts are rated for 5000 hours at 105°C and share the same operating temperature range of -25°C to 105°C. Thermal performance is equivalent.

Q: Why is the UPB2V151MHD marked as obsolete?

A: The UPB2V151MHD is an older series component. The UPT2G151MHD represents the current active equivalent from Nichicon, offering the same electrical and mechanical specifications with modern compliance certifications.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in radial, can package with through-hole mounting. The UPT2G151MHD is available in bulk packaging, consistent with standard component procurement practices.
