Substitute Part Grouping Explanation

Substitute parts for the ULD2G2R2MPD are qualified based on strict electrical and mechanical parameter matching:

Electrical Parameters (Critical for Substitution):

Capacitance: 2.2 µF (exact match required)
Voltage Rating: 400 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 15000 Hrs @ 105°C (exact match required)
Operating Temperature: -40°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
Ripple Current @ 120 Hz: 40 mA (exact match required)

Mechanical Parameters (Critical for Substitution):

Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.138" (4.60mm) (exact match required)
Diameter: 0.315" (8.00mm) (exact match required)

The two substitute parts listed—400LLE2.2MEFC8X11.5 and 400LLE2R2MEFC8X11.5 (both Rubycon LLE series)—meet all critical electrical and mechanical parameters. Minor dimensional variations in height (0.512" vs. 0.531") remain within acceptable tolerance for through-hole PCB applications.

Engineering Selection Recommendations

For Legacy System Maintenance: Both Rubycon LLE series substitutes (400LLE2.2MEFC8X11.5 and 400LLE2R2MEFC8X11.5) are qualified replacements for the ULD2G2R2MPD. The Rubycon parts carry Active product status, ensuring continued availability and supply chain stability compared to the Nichicon part's Not For New Designs classification.

Compliance Considerations: All three parts maintain ROHS3 compliance. The Rubycon substitutes offer improved REACH status (REACH Unaffected) compared to the original Nichicon part (REACH Affected), providing regulatory advantage in applications subject to REACH restrictions.

Mechanical Fit: The 0.019" (0.50mm) reduction in maximum height on the Rubycon substitutes does not impact through-hole PCB mounting compatibility. Lead spacing and diameter remain identical, ensuring direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can 400LLE2.2MEFC8X11.5 and 400LLE2R2MEFC8X11.5 be used interchangeably with ULD2G2R2MPD?

A: Yes. Both Rubycon parts meet all critical electrical specifications (2.2 µF, 400 V, ±20% tolerance, 15000 Hrs @ 105°C) and mechanical requirements (radial can package, through-hole mounting, 4.60mm lead spacing, 8.00mm diameter). The minor height difference (0.512" vs. 0.531") does not affect PCB mounting compatibility.

Q: What is the difference between 400LLE2.2MEFC8X11.5 and 400LLE2R2MEFC8X11.5?

A: Both parts are Rubycon LLE series capacitors with identical electrical and mechanical specifications. The part number variation reflects internal Rubycon designation; functionally, they are equivalent for this application. 400LLE2R2MEFC8X11.5 has significantly higher inventory availability (99967 Pcs vs. 1492 Pcs).

Q: Are there any compliance differences between the original and substitute parts?

A: All three parts are ROHS3 compliant. The Rubycon substitutes are REACH Unaffected, whereas the original Nichicon part is REACH Affected. This provides regulatory advantage in applications subject to REACH substance restrictions.

Q: Why is the ULD2G2R2MPD marked "Not For New Designs"?

A: This designation indicates Nichicon has discontinued this part for new product development. Substituting with active Rubycon LLE series parts ensures long-term supply chain availability and ongoing manufacturer support.

Q: Will the slightly shorter height of the Rubycon parts affect circuit performance?

A: No. The 0.50mm height reduction does not impact electrical performance or PCB mounting. Through-hole lead spacing and diameter remain identical, ensuring proper component seating and solder joint formation.
