Engineering Selection Recommendations

Both the LGJ2C181MELY and LGJ2D181MELY20 are active production parts from Nichicon with full ROHS3 compliance and REACH unaffected status. The LGJ2D181MELY20 functions as a direct electrical and mechanical substitute with the distinction of a higher rated voltage (200 V versus 160 V). This voltage upgrade maintains all other specifications while providing additional voltage margin in the circuit design. Selection between these parts depends on circuit voltage requirements and application design specifications. Both parts are suitable for general-purpose applications within their respective voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can the LGJ2D181MELY20 replace the LGJ2C181MELY in any application?

A: The LGJ2D181MELY20 is electrically and mechanically compatible with the LGJ2C181MELY. The 200 V rating of the substitute part is suitable for circuits designed for 160 V operation, as it provides additional voltage margin. Verify that your circuit design does not have specific voltage rating constraints that would exclude the higher-rated part.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical mechanical specifications: 0.787" diameter, 0.866" maximum seated height, 0.394" lead spacing, and radial snap-in package configuration. They are mechanically interchangeable on PCBs designed for either part.

Q: Do both parts have the same ripple current ratings?

A: Yes. Both the LGJ2C181MELY and LGJ2D181MELY20 have identical ripple current specifications: 680 mA at 120 Hz and 1.02 A at 50 kHz.

Q: What is the difference between these two parts?

A: The primary difference is the rated voltage: LGJ2C181MELY is rated at 160 V, while LGJ2D181MELY20 is rated at 200 V. All other electrical parameters, mechanical dimensions, and compliance certifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the LGJ2C181MELY and LGJ2D181MELY20 are ROHS3 compliant and REACH unaffected.
