Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LPX182M160H7P3 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Capacitance: 1800 µF
• Tolerance: ±20%
• Lead Spacing: 10.00 mm (0.394")
• Diameter: 35.00 mm (1.378")
• Height - Seated (Max): 40.00 mm (1.575")
• Mounting Type: Through Hole
• Package / Case: Radial, Can - Snap-In
• Polarization: Polar

Allowable Variation Parameters:

• Voltage - Rated: Equal to or greater than 160 V
• Operating Temperature Range: Equal to or greater than -40°C to 85°C
• Lifetime @ Temperature: Equal to or greater than 1000 Hrs @ 85°C
• ESR: Equal to or lower than 111 mOhm @ 120Hz
• Ripple Current: Equal to or greater than specified values

Both substitute parts (LAR2D182MELC40 and LLS2D182MELC) maintain identical mechanical dimensions and electrical capacitance specifications while offering rated voltages of 200 V, exceeding the original 160 V specification. This voltage upgrade provides enhanced safety margin and extended operational lifetime.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are classified as Active product status, ensuring continued manufacturer support and availability. Selection between LAR2D182MELC40 and LLS2D182MELC depends on application-specific thermal and ripple current requirements.

LAR2D182MELC40 Selection Criteria:

• Applications requiring extended operating temperature range to 105°C
• Designs with thermal management constraints at elevated temperatures
• Systems where 2000 Hrs @ 105°C lifetime specification meets or exceeds design requirements
• Moderate ripple current environments

LLS2D182MELC Selection Criteria:

• Applications operating at standard 85°C temperature with extended lifetime requirement
• High ripple current environments requiring 4.59 A @ 120 Hz or 6.885 A @ 50 kHz capability
• Designs prioritizing low-frequency ripple current performance
• Systems where 3000 Hrs @ 85°C lifetime specification provides enhanced reliability margin

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original LPX182M160H7P3. The 200 V rated voltage of both substitutes exceeds the original 160 V specification, providing increased electrical safety margin without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can LAR2D182MELC40 or LLS2D182MELC be directly substituted for LPX182M160H7P3 without PCB modification?

A: Yes. Both substitute parts maintain identical mechanical dimensions (35.00 mm diameter, 40.00 mm height, 10.00 mm lead spacing) and mounting type (through-hole, radial snap-in). Direct board-level substitution is mechanically compatible without PCB redesign.

Q: What is the significance of the 200 V rated voltage on substitute parts versus the original 160 V specification?

A: The 200 V rating on LAR2D182MELC40 and LLS2D182MELC represents a 25% voltage margin increase over the original LPX182M160H7P3. This higher voltage rating does not affect circuit operation at 160 V or lower; it provides enhanced electrical safety margin and typically extends component lifetime under identical thermal conditions.

Q: How do the lifetime specifications differ between the three parts?

A: LPX182M160H7P3 specifies 1000 Hrs @ 85°C. LAR2D182MELC40 specifies 2000 Hrs @ 105°C, indicating extended lifetime at higher temperature. LLS2D182MELC specifies 3000 Hrs @ 85°C, providing the longest lifetime at standard operating temperature. Selection depends on application thermal profile and required reliability margin.

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

A: Yes. At 120 Hz, LPX182M160H7P3 handles 3.7 A, LAR2D182MELC40 handles 3.08 A, and LLS2D182MELC handles 4.59 A. At 50 kHz, LPX182M160H7P3 handles 4.07 A, LAR2D182MELC40 handles 4.62 A, and LLS2D182MELC handles 6.885 A. Applications with high low-frequency ripple current should select LLS2D182MELC.

Q: Do all three parts meet the same regulatory compliance standards?

A: Yes. LPX182M160H7P3, LAR2D182MELC40, and LLS2D182MELC are all ROHS3 compliant, REACH unaffected, classified as EAR99, and share HTSUS code 8532.22.0040. Regulatory substitution is fully supported.

Q: What is the difference between the LAR and LLS series from Nichicon?

A: Both are Nichicon aluminum electrolytic capacitors in identical physical packages. LAR2D182MELC40 prioritizes extended high-temperature operation (105°C). LLS2D182MELC prioritizes extended lifetime at standard temperature (85°C) with superior ripple current handling. Series selection depends on thermal environment and ripple current demands.

Q: Can these parts be used interchangeably in the same design?

A: Mechanical and electrical interchangeability is confirmed for direct substitution. However, thermal and ripple current performance characteristics differ. Design validation should confirm that the selected substitute meets specific application thermal and current requirements.
