LGU2P271MELY Equivalent & Substitute Parts

Part Overview

The LGU2P271MELY is a 270 µF, 220 V aluminum electrolytic capacitor manufactured by Nichicon in the LGU series. This radial, can-style snap-in capacitor is designed for general-purpose applications with a rated lifetime of 3000 hours at 105°C and an operating temperature range of -40°C to 105°C. The part is currently active in production status. Equivalent and substitute parts are identified when design requirements allow for higher voltage ratings or when inventory constraints necessitate alternative sourcing while maintaining functional compatibility.

Substitute Part Grouping Explanation

Substitution of the LGU2P271MELY is permissible when the following conditions are met:

Primary Substitution Criteria:

• Capacitance value remains 270 µF (±20% tolerance maintained)
• Voltage rating is equal to or greater than 220 V
• Polarization remains polar
• Package type remains radial, can-style snap-in
• Mounting type remains through-hole
• Physical dimensions (lead spacing, diameter, height) remain identical
• Operating temperature range encompasses -40°C to 105°C
• Lifetime rating is 3000 hours or greater at 105°C
• RoHS3 compliance is maintained

The LGU2E271MELY qualifies as a direct substitute based on these parameters, with the distinction of a higher voltage rating (250 V versus 220 V), which provides additional design margin without affecting functional compatibility in the original application.

Parameter Comparison

Engineering Selection Recommendations

Both the LGU2P271MELY and LGU2E271MELY are active production parts with ROHS3 compliance and REACH unaffected status. The LGU2E271MELY operates at a higher voltage rating (250 V) while maintaining identical physical dimensions, capacitance value, tolerance, and thermal characteristics. Selection between these parts should be based on circuit voltage requirements and application constraints. The higher voltage rating of the substitute part does not introduce incompatibility with circuits designed for 220 V operation. Both parts maintain equivalent mechanical fit and electrical performance within their respective voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can the LGU2E271MELY replace the LGU2P271MELY in a 220 V circuit?

A: Yes. The LGU2E271MELY is rated for 250 V, which exceeds the 220 V requirement of the original circuit. Higher voltage-rated capacitors are functionally compatible in lower-voltage applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical lead spacing (10.00mm), diameter (20.00mm), and maximum seated height (35.00mm), ensuring mechanical compatibility on PCBs designed for the LGU2P271MELY.

Q: What is the difference in ripple current ratings?

A: The LGU2P271MELY carries ripple current ratings of 1.15 A @ 120 Hz and 1.725 A @ 50 kHz. The LGU2E271MELY carries 1.1 A @ 120 Hz and 1.65 A @ 50 kHz. Both ratings remain within acceptable ranges for general-purpose applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LGU2P271MELY and LGU2E271MELY are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: Is the capacitance tolerance the same?

A: Yes. Both parts maintain ±20% capacitance tolerance, ensuring equivalent performance in tolerance-sensitive circuits.

Q: What is the thermal lifetime specification?

A: Both parts are rated for 3000 hours at 105°C, providing identical thermal endurance characteristics across the operating temperature range of -40°C to 105°C.
