Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the LPX122M160C4P3 is based on the following mandatory alignment criteria:

Critical Matching Parameters:

• Capacitance value: 1200 µF (exact match required)
• Voltage rating: 160 V (substitute must equal or exceed)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Mounting type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Acceptable Variation Parameters:

• Physical dimensions (diameter and height) may vary within mechanical compatibility limits
• ESR values may differ based on manufacturer design
• Ripple current ratings may exceed the original specification
• Lifetime at temperature may exceed the original specification
• Operating temperature range may extend beyond the original specification

Substitute parts identified for the LPX122M160C4P3 are classified into two categories:

Direct Equivalent: LLG2C122MELZ40 (Nichicon) - Matches all critical parameters with extended lifetime performance (2000 Hrs @ 85°C).

Upgrade Equivalent: LGU2C122MELA (Nichicon) - Matches all critical parameters with enhanced thermal performance (3000 Hrs @ 105°C) and extended operating temperature range (-40°C ~ 105°C).

Parameter Comparison

Engineering Selection Recommendations

LLG2C122MELZ40 (Nichicon) - Direct Equivalent:

This substitute maintains identical electrical and mechanical specifications to the LPX122M160C4P3 while providing doubled lifetime performance (2000 Hrs @ 85°C versus 1000 Hrs @ 85°C). The component is ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements. Physical dimensions differ slightly (0.866" diameter versus 0.984" diameter), requiring verification of available PCB space. Lead spacing and mounting type remain identical, ensuring direct footprint compatibility. This option is suitable for applications where the original specification is adequate but extended component life is beneficial.

LGU2C122MELA (Nichicon) - Upgrade Equivalent:

This substitute provides enhanced thermal performance with a 3000-hour lifetime at 105°C and an extended operating temperature range (-40°C ~ 105°C). Physical dimensions match the original part exactly (0.984" diameter, 1.772" height), ensuring identical PCB footprint compatibility. ROHS3 compliance and REACH unaffected status maintain regulatory alignment. This option is recommended for applications requiring extended temperature operation or enhanced reliability margins. The upgrade classification reflects superior performance characteristics within the same mechanical envelope.

Both substitutes are Active product status with current inventory availability, ensuring procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can LLG2C122MELZ40 be used as a direct replacement for LPX122M160C4P3?

A: Yes. The LLG2C122MELZ40 matches all critical electrical parameters (1200 µF, 160 V, ±20% tolerance) and package specifications (radial snap-in, 10.00mm lead spacing, through-hole mounting). The primary difference is reduced physical diameter (22.00mm versus 25.00mm), which requires verification that available PCB space accommodates the smaller component. Lifetime performance is superior (2000 Hrs @ 85°C).

Q: What is the difference between the two substitute parts?

A: LLG2C122MELZ40 provides equivalent electrical performance with doubled lifetime at 85°C. LGU2C122MELA provides the same lifetime advantage plus extended operating temperature range (to 105°C) and identical physical dimensions to the original part. Selection depends on thermal environment requirements and available PCB space.

Q: Are both substitutes RoHS and REACH compliant?

A: Yes. Both LLG2C122MELZ40 and LGU2C122MELA are ROHS3 compliant and REACH unaffected, matching the regulatory status of the LPX122M160C4P3.

Q: Does the smaller diameter of LLG2C122MELZ40 affect circuit performance?

A: Diameter reduction does not affect electrical performance. All critical parameters (capacitance, voltage, tolerance, ESR characteristics, ripple current ratings) remain within specification. Physical diameter affects only PCB layout compatibility and available mounting space.

Q: Can these substitutes be used in applications operating above 85°C?

A: LLG2C122MELZ40 is rated for -40°C ~ 85°C operation, matching the original part's temperature range. LGU2C122MELA extends the upper operating limit to 105°C and is suitable for elevated-temperature applications. Verify application thermal requirements before selection.

Q: Are all three parts available in current inventory?

A: Yes. LPX122M160C4P3 (1005 Pcs), LLG2C122MELZ40 (1022 Pcs), and LGU2C122MELA (1017 Pcs) are all listed as new original stock with active product status.
