Engineering Selection Recommendations

LGU2C122MELC (Direct Equivalent - Nichicon)

This part is a direct equivalent to the LPX122M160H3P3. All mechanical dimensions, lead spacing, package configuration, and electrical base specifications are identical. The LGU2C122MELC maintains the same 160 V voltage rating and 1200 µF capacitance with ±20% tolerance. The substitute offers extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C) and significantly improved lifetime rating (3000 Hrs @ 105°C versus 1000 Hrs @ 85°C). Both parts are ROHS3 Compliant and Active product status. This substitute is suitable for direct replacement in applications where the original part is unavailable.

LAR2D122MELC30 (Upgrade - Nichicon)

This part is classified as an upgrade substitute due to its higher voltage rating of 200 V compared to the 160 V main part. All other mechanical specifications remain identical: 1200 µF capacitance, ±20% tolerance, 10.00 mm lead spacing, 35.00 mm diameter, 30.00 mm maximum seated height, radial snap-in package, and through-hole mounting. The LAR2D122MELC30 extends the operating temperature range to -40°C ~ 105°C and provides 2000 Hrs @ 105°C lifetime. The higher voltage rating provides additional design margin in applications operating at or near 160 V. Both parts are ROHS3 Compliant and Active product status. This substitute is suitable for replacement in applications where voltage headroom is beneficial or required.

Frequently Asked Questions (FAQ)

Q: Can LGU2C122MELC be used as a direct replacement for LPX122M160H3P3?

A: Yes. The LGU2C122MELC is a direct equivalent. All critical parameters match: 1200 µF capacitance, ±20% tolerance, 160 V voltage rating, 10.00 mm lead spacing, 35.00 mm diameter, 30.00 mm height, radial snap-in package, through-hole mounting, and ROHS3 compliance. The substitute offers improved thermal performance and extended lifetime.

Q: What is the difference between the direct equivalent and upgrade substitute?

A: The LGU2C122MELC is a direct equivalent with identical 160 V voltage rating. The LAR2D122MELC30 is an upgrade with a higher 200 V voltage rating. Both maintain identical mechanical dimensions and capacitance specifications. The upgrade provides additional voltage margin for applications requiring higher safety factor or operating near maximum voltage limits.

Q: Are the mechanical dimensions identical across all three parts?

A: Yes. The LPX122M160H3P3, LGU2C122MELC, and LAR2D122MELC30 all share identical mechanical specifications: 35.00 mm diameter, 30.00 mm maximum seated height, 10.00 mm lead spacing, radial snap-in package, and through-hole mounting configuration. All parts are mechanically interchangeable on PCB layouts designed for the original part.

Q: Can the 200 V rated LAR2D122MELC30 be used in a circuit designed for 160 V?

A: Yes. The LAR2D122MELC30 with 200 V rating is suitable for use in circuits designed for 160 V operation. Higher voltage-rated capacitors are backward compatible with lower voltage applications. The 200 V rating provides additional design margin and does not negatively impact circuit performance at 160 V operation.

Q: What is the lead spacing and how does it affect PCB compatibility?

A: All three parts have 10.00 mm lead spacing. This dimension defines the distance between the two radial leads and directly corresponds to the PCB footprint hole pattern. Identical lead spacing ensures mechanical compatibility without PCB redesign.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The LPX122M160H3P3, LGU2C122MELC, and LAR2D122MELC30 are all ROHS3 Compliant. All parts meet regulatory requirements for hazardous substance restrictions.

Q: What is the difference in operating temperature range?

A: The main part LPX122M160H3P3 operates from -40°C to 85°C. Both substitutes (LGU2C122MELC and LAR2D122MELC30) operate from -40°C to 105°C. The extended upper temperature limit of the substitutes provides improved performance in higher ambient temperature environments.

Q: How do the lifetime ratings compare?

A: The LPX122M160H3P3 is rated for 1000 Hrs @ 85°C. The LGU2C122MELC provides 3000 Hrs @ 105°C. The LAR2D122MELC30 provides 2000 Hrs @ 105°C. Higher lifetime ratings indicate longer expected operational life under specified thermal conditions.
