Key Parameters

Substitute Part Grouping Explanation

Substitution of the UTM1E331MHD1TN is determined by the following critical parameters:

• Capacitance Value: Must be 330 µF (exact match required)
• Voltage Rating: Minimum 25 V; higher ratings are acceptable for backward compatibility
• Tolerance: ±20% (standard tolerance for this category)
• Package Type: Radial, can configuration with through-hole mounting
• Lead Spacing: 0.295" (7.50mm) for PCB compatibility
• Physical Dimensions: Compatible can diameter and height within acceptable mechanical tolerances

The UBX1V331MHL1TN meets these substitution criteria while offering enhanced performance characteristics including higher voltage rating (35 V), extended operating temperature range (-55°C ~ 150°C), and improved lifetime rating (2000 Hrs @ 150°C).

Engineering Selection Recommendations

The UBX1V331MHL1TN is a direct functional substitute for the obsolete UTM1E331MHD1TN. Selection of this substitute is supported by:

• Product Status: The substitute is active and in production, ensuring long-term availability and supply chain continuity
• Electrical Compatibility: Identical capacitance and tolerance values with higher voltage rating provide enhanced design margin
• Mechanical Compatibility: Matching lead spacing (7.50mm) and can diameter (16.00mm) ensure PCB footprint compatibility; maximum height difference of 0.019" (0.50mm) is within standard mechanical tolerances
• Compliance: The substitute carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements
• Performance Enhancement: Extended operating temperature range and improved lifetime rating at elevated temperature provide superior reliability characteristics

Frequently Asked Questions (FAQ)

Q: Can the UBX1V331MHL1TN be used as a direct replacement for the UTM1E331MHD1TN?

A: Yes. Both components share identical capacitance (330 µF), tolerance (±20%), lead spacing (7.50mm), and package type (radial, can, through-hole). The substitute has a higher voltage rating (35 V vs. 25 V) and extended operating temperature range, making it electrically and mechanically compatible.

Q: What is the height difference between these two capacitors?

A: The UTM1E331MHD1TN has a maximum seated height of 1.024" (26.00mm), while the UBX1V331MHL1TN has a maximum seated height of 1.043" (26.50mm). The difference of 0.019" (0.50mm) is within standard mechanical tolerances for through-hole radial capacitors and does not affect PCB assembly compatibility.

Q: Are there any compliance differences between the main part and substitute?

A: The substitute (UBX1V331MHL1TN) is RoHS3 compliant and REACH unaffected. The main part status for these certifications was not provided in the original specifications. Both parts carry the same ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Q: Why is the main part obsolete?

A: The UTM1E331MHD1TN is listed as obsolete. The UBX1V331MHL1TN is an active product from the same manufacturer, ensuring continued availability and support for applications requiring this capacitance and voltage rating.

Q: Does the higher voltage rating of the substitute affect circuit performance?

A: No. A capacitor with a higher voltage rating operates identically to one with a lower rating when used within the lower voltage specification. The 35 V rating of the substitute provides additional design margin without affecting electrical performance in circuits designed for 25 V operation.
