Key Parameters

Substitute Part Grouping Explanation

Substitution of the 128LBA160M2ED is determined by strict equivalence in the following critical parameters:

Mandatory Equivalence Parameters:

• Capacitance: 1200 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Physical Dimensions: 1.378" Dia (35.00mm) and 1.260" Height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: Equal to or greater than 160 V
• Operating Temperature: Equal to or greater than the specified range
• Lifetime @ Temp.: May vary based on manufacturer design
• ESR (Equivalent Series Resistance): May vary within acceptable limits
• Ripple Current: May vary based on manufacturer specifications

The substitute part LGN2D122MELC30 meets all mandatory equivalence criteria and provides enhanced electrical performance through higher voltage rating (200 V) and extended operating temperature range (-40°C ~ 105°C).

Engineering Selection Recommendations

Primary Part: 128LBA160M2ED

The Cornell Dubilier 128LBA160M2ED is suitable for applications operating at or below 160 V with ambient temperatures not exceeding 85°C. This component carries Active product status and maintains full ROHS3 compliance and REACH unaffected designation, confirming regulatory alignment for industrial and commercial deployment.

Substitute Part: LGN2D122MELC30

The Nichicon LGN2D122MELC30 provides direct functional substitution with enhanced performance margins. The 200 V voltage rating provides 25% additional voltage headroom above the primary part specification. The extended operating temperature range to 105°C accommodates applications requiring elevated thermal performance. Both components maintain identical mechanical form factor, lead spacing, and mounting configuration, ensuring direct PCB compatibility without layout modification. Both parts carry Active product status with ROHS3 compliance and REACH unaffected status.

Selection between these parts depends on application voltage requirements and thermal operating conditions. The substitute part is appropriate for circuits operating at voltages up to 200 V or in environments where sustained temperatures approach or exceed 85°C.

Frequently Asked Questions (FAQ)

Q: Can the LGN2D122MELC30 be used as a direct replacement for the 128LBA160M2ED in all applications?

A: The LGN2D122MELC30 is mechanically and electrically compatible for direct substitution in circuits where the operating voltage does not exceed 200 V and ambient temperature does not exceed 105°C. The identical physical dimensions, lead spacing, and snap-in mounting configuration permit direct PCB installation without modification.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The LGN2D122MELC30 is rated for 200 V compared to the 160 V rating of the primary part. This higher voltage rating provides additional safety margin in circuits operating near the maximum voltage specification of the primary part. The substitute part remains fully functional in circuits designed for 160 V operation.

Q: Are there differences in ripple current handling between these parts?

A: Ripple current specifications differ between the two parts. The 128LBA160M2ED specifies 3.2 A @ 120 Hz and 4.704 A @ 10 kHz. The LGN2D122MELC30 specifies 2.65 A @ 120 Hz and 3.975 A @ 50 kHz. Applications requiring specific ripple current performance should verify compatibility with the substitute part's ratings.

Q: Do both parts meet the same regulatory requirements?

A: Both the 128LBA160M2ED and LGN2D122MELC30 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.22.0040. Regulatory compliance is equivalent between the two parts.

Q: What is the difference in lifetime specifications?

A: The 128LBA160M2ED specifies 2000 hours at 85°C. The LGN2D122MELC30 specifies 3000 hours at 105°C. The substitute part demonstrates extended operational life at higher temperature, indicating enhanced thermal stability in the component design.

Q: Can these parts be used interchangeably in existing designs without PCB modification?

A: Yes. Both parts share identical physical dimensions (1.378" diameter, 1.260" height), lead spacing (0.394" / 10.00mm), and snap-in mounting configuration. Direct substitution on existing PCBs is possible without layout changes.

Q: What is the capacitance tolerance for both parts?

A: Both the 128LBA160M2ED and LGN2D122MELC30 carry ±20% capacitance tolerance. This tolerance applies equally to both parts and should be considered in circuit design calculations.
