Key Parameters

Substitute Part Grouping Explanation

Substitution of the ULD2G2R2MPD6 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 2.2 µF (exact match required)
• Voltage rating: 400 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lifetime rating: 12000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Lead spacing: 0.138" (4.60mm) (exact match required for PCB compatibility)
• Package diameter: 0.315" Dia (8.00mm) (exact match required for mechanical fit)
• Height - Seated (Max): 0.433" (11.00mm) (exact match required for mechanical fit)
• Mounting type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The 400LLE2R2MEFC8X9 manufactured by Rubycon meets all critical substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 400LLE2R2MEFC8X9 (Rubycon) is a direct parametric equivalent to the obsolete ULD2G2R2MPD6 (Nichicon). Both components satisfy identical electrical and mechanical specifications, including capacitance, voltage rating, tolerance, lifetime rating, operating temperature range, and physical dimensions. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The Rubycon substitute carries a product status of "Not For New Designs," indicating it is also in end-of-life phase. For new system designs, consultation with component suppliers for current production alternatives meeting the same electrical and mechanical parameters is recommended.

Frequently Asked Questions (FAQ)

Q: Can the 400LLE2R2MEFC8X9 be used as a direct replacement for the ULD2G2R2MPD6?

A: Yes. Both components share identical electrical ratings (2.2 µF, 400 V, ±20% tolerance), identical thermal specifications (12000 Hrs @ 105°C, -40°C ~ 105°C operating range), and identical mechanical dimensions (0.315" diameter, 0.433" height, 0.138" lead spacing). Through-hole mounting compatibility is confirmed.

Q: Are there differences in ripple current ratings between these parts?

A: The ripple current at low frequency (120 Hz) differs slightly: ULD2G2R2MPD6 is rated at 33 mA, while 400LLE2R2MEFC8X9 is rated at 36 mA. This difference does not affect substitution eligibility, as the Rubycon part provides equal or superior performance in this parameter.

Q: Do both parts meet current compliance standards?

A: Yes. Both the ULD2G2R2MPD6 and 400LLE2R2MEFC8X9 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the significance of the "Not For New Designs" status on the Rubycon part?

A: This designation indicates the component is in end-of-life phase and is not recommended for incorporation into new product designs. It remains suitable for repair and maintenance of existing systems. For new designs, current production alternatives with equivalent specifications should be sourced.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both components have identical lead spacing (0.138" / 4.60mm), package diameter (0.315" / 8.00mm), and maximum seated height (0.433" / 11.00mm), ensuring direct mechanical compatibility in through-hole PCB applications.
