LPX122M200E4P3 Equivalent & Substitute Parts

Part Overview

The LPX122M200E4P3 is a 1200 µF, 200 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is designed for general-purpose applications requiring high capacitance at 200 V rated voltage with a through-hole mounting configuration. The part is Active status and ROHS3 compliant.

Substitute parts are identified when equivalent electrical performance can be achieved through alternative manufacturers or series while maintaining core functional parameters: capacitance value, voltage rating, tolerance, polarization, and mounting type. Substitutes may offer improved thermal performance, extended operational lifetime, or enhanced ripple current handling.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following core parameters:

Primary Substitution Criteria:

• Capacitance: 1200 µF (exact match required)
• Voltage Rating: 200 V minimum (equal or higher acceptable)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)

Secondary Performance Parameters (may vary):

• ESR (Equivalent Series Resistance)
• Lifetime @ Temperature
• Operating Temperature Range
• Ripple Current ratings
• Physical dimensions (height and diameter)

All identified substitutes meet the primary criteria. Variations in secondary parameters reflect different manufacturer designs and thermal performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Same Voltage Rating - 200 V):

SLPX122M200E7P3 and SLPX122M200H5P3 are Cornell Dubilier Electronics components within the SLPX series. Both maintain identical electrical specifications to the LPX122M200E4P3 (capacitance, voltage, tolerance, ESR) while offering extended thermal lifetime (3000 Hrs @ 85°C versus 1000 Hrs @ 85°C). SLPX122M200E7P3 maintains the original 30mm diameter with reduced height (40mm). SLPX122M200H5P3 features increased diameter (35mm) and reduced height (35mm). Both are ROHS3 compliant and Active status.

LLS2D122MELB is a Nichicon component (LLS series) providing equivalent electrical performance with 3000 Hrs @ 85°C lifetime. Physical dimensions are 30mm diameter and 35mm height. ROHS3 compliant and Active status.

LGW2D122MELB40 is a Nichicon component (LGW series) rated for extended temperature operation (-40°C ~ 105°C) with 3000 Hrs @ 105°C lifetime. Maintains 30mm diameter and 40mm height. ROHS3 compliant and Active status.

Upgrade Option (Higher Voltage Rating - 250 V):

LAR2E122MELB45 is a Nichicon component with 250 V rated voltage, providing voltage margin above the 200 V requirement. Rated for 2000 Hrs @ 105°C with extended temperature range (-40°C ~ 105°C). Maintains 30mm diameter and 45mm height. ROHS3 compliant and Active status. This part is suitable for applications requiring additional voltage safety margin.

All identified substitutes are ROHS3 compliant, REACH unaffected, and carry Active product status.

Frequently Asked Questions (FAQ)

Q: Can SLPX122M200E7P3 or SLPX122M200H5P3 be used as direct replacements for LPX122M200E4P3?

A: Yes. Both SLPX series parts maintain identical capacitance (1200 µF), voltage rating (200 V), tolerance (±20%), ESR (166 mOhm @ 120Hz), polarization, package type, and lead spacing. The primary difference is extended thermal lifetime (3000 Hrs @ 85°C versus 1000 Hrs @ 85°C) and reduced physical height. Verify PCB layout accommodates the height variation: SLPX122M200E7P3 is 40mm height; SLPX122M200H5P3 is 35mm height.

Q: What is the difference between LGW2D122MELB40 and LLS2D122MELB?

A: Both are Nichicon 1200 µF, 200 V snap-in capacitors with identical lead spacing and diameter (30mm). LGW2D122MELB40 operates to 105°C with 3000 Hrs @ 105°C rating and 40mm height. LLS2D122MELB operates to 85°C with 3000 Hrs @ 85°C rating and 35mm height. Select LGW2D122MELB40 for applications requiring higher temperature operation; select LLS2D122MELB for space-constrained designs.

Q: When should LAR2E122MELB45 be selected instead of direct equivalents?

A: LAR2E122MELB45 features 250 V rated voltage, providing 50 V margin above the 200 V requirement. Select this part for applications where voltage transient protection or design safety margin is required. Note: ripple current rating is lower (2.3 A @ 120 Hz) compared to the main part (3.5 A @ 120 Hz).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (SLPX122M200E7P3, SLPX122M200H5P3, LGW2D122MELB40, LLS2D122MELB, LAR2E122MELB45) are ROHS3 compliant and REACH unaffected.

Q: What physical dimensions must be verified before substitution?

A: Verify two dimensions: (1) Diameter: all substitutes maintain 30mm except SLPX122M200H5P3 (35mm); (2) Height: LPX122M200E4P3 is 45mm, SLPX122M200E7P3 is 40mm, SLPX122M200H5P3 is 35mm, LGW2D122MELB40 is 40mm, LLS2D122MELB is 35mm, LAR2E122MELB45 is 45mm. Confirm PCB layout and clearance accommodate selected substitute height.

Q: Can substitutes be mixed in the same assembly?

A: All substitutes meet identical electrical specifications for capacitance, voltage, tolerance, and polarization. However, physical height variations may require separate PCB layout considerations. Consult design documentation to determine if mixed substitutes are acceptable for your application.
