Key Parameters

Substitute Part Grouping Explanation

Substitution of the URS1E331MPD1TD is determined by the following critical parameters:

• Capacitance Value: Must be 330 µF (exact match required)
• Voltage Rating: Substitute must be rated at 25 V or higher
• Tolerance: ±20% tolerance maintained
• Polarization: Polar configuration required
• Package Type: Radial, can package with through-hole mounting
• Lead Spacing: 0.197" (5.00mm) pitch for PCB compatibility
• Diameter: 0.394" (10.00mm) maximum diameter constraint
• Compliance: ROHS3 compliant status required

The Rubycon 35ZLH330MEFCT810X12.5 meets all substitution criteria with identical capacitance, tolerance, polarization, lead spacing, and diameter specifications. The higher voltage rating (35 V vs. 25 V) and improved lifetime rating provide enhanced reliability margins without affecting circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Rubycon 35ZLH330MEFCT810X12.5 is a direct substitute for the obsolete Nichicon URS1E331MPD1TD. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing environments.

The substitute part provides superior performance characteristics: higher voltage rating (35 V), extended operating temperature range (-40°C to 105°C), and significantly improved lifetime rating (10000 Hrs @ 105°C versus 2000 Hrs @ 85°C). These enhancements deliver increased reliability margins without requiring circuit redesign or PCB layout modifications.

Physical compatibility is confirmed across all critical dimensions: identical lead spacing (5.00mm), diameter (10.00mm), and radial can package configuration ensure direct drop-in replacement capability on existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the Rubycon 35ZLH330MEFCT810X12.5 be used as a direct replacement for the Nichicon URS1E331MPD1TD?

A: Yes. Both components share identical capacitance (330 µF), tolerance (±20%), polarization (polar), lead spacing (5.00mm), and physical diameter (10.00mm). The substitute meets all electrical and mechanical compatibility requirements for direct PCB substitution.

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

A: The Rubycon part is rated at 35 V compared to the original 25 V rating. This higher voltage rating provides additional safety margin in the circuit and does not affect compatibility. The component operates safely at the original 25 V circuit voltage.

Q: Are there any height differences between these components?

A: Yes. The Nichicon URS1E331MPD1TD has a maximum seated height of 0.413" (10.50mm), while the Rubycon 35ZLH330MEFCT810X12.5 has a maximum seated height of 0.551" (14.00mm). Verify clearance in the target application before substitution.

Q: Do both parts meet current compliance standards?

A: Yes. Both the original and substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the advantage of the substitute part's extended lifetime rating?

A: The Rubycon substitute is rated for 10000 Hrs @ 105°C compared to 2000 Hrs @ 85°C for the original. This extended lifetime rating indicates improved long-term reliability and reduced failure risk in field applications.
