Key Parameters

Substitute Part Grouping Explanation

Substitution of the UBT1H2R2MPD8 is determined by the following critical parameters:

• Capacitance Value: Must be 2.2 µF (±20% tolerance acceptable)
• Voltage Rating: Minimum 50 V; higher voltage ratings are acceptable for circuit compatibility
• Package Geometry: Radial, can package with matching lead spacing (0.138" / 4.60mm) and physical dimensions (0.315" Dia × 0.531" Height Max)
• Polarization: Polar configuration required
• Mounting Type: Through-hole mounting
• Operating Temperature Range: Must support -40°C ~ 125°C minimum
• Compliance: ROHS3 compliance required for equivalent substitution

The substitute part 400LEX2.2MEFC8X11.5 meets these criteria with identical capacitance, tolerance, package geometry, and operating temperature range. The higher voltage rating (400 V vs. 50 V) and extended lifetime rating do not prevent substitution in circuits designed for 50 V operation.

Parameter Comparison

Engineering Selection Recommendations

The 400LEX2.2MEFC8X11.5 (Rubycon LEX series) is a direct substitute for the discontinued UBT1H2R2MPD8. Both components share identical electrical specifications (2.2 µF, ±20% tolerance), matching physical dimensions, and equivalent operating temperature ranges. The substitute part maintains ROHS3 compliance and supports the same through-hole mounting configuration.

The 400 V voltage rating of the substitute part exceeds the original 50 V specification, which is acceptable for circuits designed for 50 V operation. The extended lifetime rating (5000 Hrs @ 125°C vs. 2000 Hrs @ 125°C) provides improved reliability margins without introducing compatibility concerns.

Frequently Asked Questions (FAQ)

Q: Can the 400LEX2.2MEFC8X11.5 be used as a direct replacement for the UBT1H2R2MPD8?

A: Yes. Both parts have identical capacitance (2.2 µF), tolerance (±20%), operating temperature range (-40°C ~ 125°C), and physical dimensions. The matching lead spacing (4.60mm) and package geometry (radial, can) ensure direct PCB compatibility.

Q: Does the higher voltage rating (400 V) of the substitute part affect circuit operation?

A: No. A capacitor with a higher voltage rating operates normally in circuits designed for lower voltages. The 400 V rating provides additional safety margin and does not alter the electrical behavior in a 50 V circuit.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant. The substitute part is REACH Unaffected, while the original is REACH Affected. This difference does not impact electrical substitution.

Q: What is the significance of the extended lifetime rating on the substitute part?

A: The 400LEX2.2MEFC8X11.5 is rated for 5000 hours at 125°C compared to 2000 hours for the UBT1H2R2MPD8. This extended rating indicates improved thermal stability and longer operational life under elevated temperature conditions, providing a reliability advantage without introducing substitution concerns.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both parts have identical case dimensions (0.315" diameter, 0.531" maximum seated height) and lead spacing (0.138" / 4.60mm), ensuring direct PCB footprint compatibility.
