LP182M200H9P3 Equivalent & Substitute Parts

Part Overview

The LP182M200H9P3 is a 1800 µF, 200 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is classified as Active product status and is designed for general-purpose applications requiring high capacitance values at moderate voltage ratings. The part is RoHS3 compliant and REACH unaffected, suitable for industrial and commercial electronic systems.

Substitute parts become necessary when the original component experiences extended lead times, inventory constraints, or when design requirements permit operation at higher voltage ratings while maintaining identical physical dimensions and electrical characteristics.

Substitute Part Grouping Explanation

Substitution of the LP182M200H9P3 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance: 1800 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -40°C to 105°C (exact match required)
• Polarization: Polar (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Size / Dimension: 35.00 mm Dia (exact match required)
• Height - Seated (Max): 50.00 mm (exact match required)
• Mounting Type: Through Hole (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 200 V
• Lifetime @ Temp.: May be equal to or greater than 1000 Hrs @ 105°C
• Ripple Current: May be equal to or greater than specified values

The substitute part LGW2E182MELC50 manufactured by Nichicon meets all critical matching parameters and exceeds allowable variation parameters, qualifying it as a direct substitute.

Engineering Selection Recommendations

The LGW2E182MELC50 (Nichicon) qualifies as a direct substitute for the LP182M200H9P3 (CDE) based on the following engineering criteria:

Compliance and Certification Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in applications subject to environmental directives.

Physical and Electrical Compatibility: Identical physical dimensions (35.00 mm diameter, 50.00 mm height, 10.00 mm lead spacing) and mounting configuration (through-hole, radial snap-in) ensure direct PCB compatibility without layout modifications.

Electrical Performance Enhancement: The substitute part operates at 250 V rated voltage compared to 200 V, providing increased voltage margin in applications operating below 200 V. The extended lifetime rating of 3000 Hrs @ 105°C versus 1000 Hrs @ 105°C indicates improved thermal stability and component longevity.

Ripple Current Capability: Higher ripple current ratings (4.05 A @ 120 Hz and 6.075 A @ 50 kHz) in the substitute part provide additional thermal margin in high-ripple-current applications.

Product Status: Both components maintain Active product status, ensuring continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the LGW2E182MELC50 be used as a direct replacement for the LP182M200H9P3 in existing designs?

A: Yes. The substitute part maintains identical capacitance (1800 µF), tolerance (±20%), operating temperature range (-40 to 105°C), physical dimensions (35.00 mm diameter, 50.00 mm height), lead spacing (10.00 mm), and mounting configuration (through-hole radial snap-in). No PCB modifications are required.

Q: What is the voltage rating difference, and does it affect compatibility?

A: The substitute part is rated at 250 V compared to the original 200 V rating. This higher voltage rating is compatible with all applications designed for 200 V operation, as the component can safely operate at lower voltages than its maximum rating.

Q: Are there differences in thermal performance between these parts?

A: The LGW2E182MELC50 provides extended thermal performance with a 3000 Hrs @ 105°C lifetime rating compared to 1000 Hrs @ 105°C for the LP182M200H9P3. This indicates improved reliability in high-temperature environments.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the LP182M200H9P3 and LGW2E182MELC50 are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory standards.

Q: Is the ripple current rating difference significant?

A: The substitute part provides higher ripple current capability (4.05 A @ 120 Hz versus 3.8 A @ 120 Hz). This additional margin is beneficial in applications with high AC ripple current but does not affect compatibility in designs operating within the original part's ripple current specifications.

Q: Can the parts be intermixed in inventory?

A: Both components are packaged in bulk and maintain identical physical form factors. However, part number identification should be maintained during inventory management to ensure traceability and compliance documentation.
