LKX2D152MESC40 Equivalent & Substitute Parts

Part Overview

The LKX2D152MESC40 is a 1500 µF, 200 V aluminum electrolytic capacitor manufactured by Nichicon in the LKX series. This radial, snap-in can capacitor is designed for audio applications with a rated lifetime of 2000 hours at 105°C. The part is active and in stock with full RoHS3 compliance.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements demand higher voltage ratings or extended lifetime specifications, or when alternative manufacturers' components meet the same electrical and mechanical parameters within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LKX2D152MESC40 is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 1500 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Size / Dimension: 1.378" Dia (35.00 mm) (exact match required)
• Height - Seated (Max): 1.654" (42.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: Equal to or greater than 200 V
• Lifetime @ Temperature: Equal to or greater than 2000 Hrs @ 105°C
• Operating Temperature Range: Must encompass -40°C ~ 105°C minimum
• RoHS Status: ROHS3 Compliant or equivalent

All substitute parts listed below meet these criteria and are manufactured by Nichicon or Cornell Dubilier Electronics (CDE), both established suppliers of aluminum electrolytic capacitors.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with full RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

LGG2E152MELC40 (Nichicon LGG Series): Provides a 250 V rated voltage, exceeding the 200 V requirement of the main part. Maintains identical 2000-hour lifetime specification and mechanical compatibility. Suitable for direct substitution in applications where higher voltage margin is acceptable.

LGN2P152MELC40 (Nichicon LGN Series): Offers 220 V rated voltage and extended 3000-hour lifetime at 105°C, providing both voltage and reliability improvements over the main part. Maintains full mechanical and electrical compatibility. Suitable for applications requiring enhanced reliability or longer service intervals.

381LR152M200A042 (Cornell Dubilier Electronics 381LR Series): Matches the 200 V voltage rating of the main part while providing extended 3000-hour lifetime. Specifies 99 mOhm ESR at 120 Hz. Suitable for direct substitution where manufacturer diversification is required.

381LX152M200A042 (Cornell Dubilier Electronics 381LX Series): Matches the 200 V voltage rating and provides extended 3000-hour lifetime. Maintains full mechanical and electrical compatibility. Suitable for direct substitution where manufacturer diversification is required.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the original LKX2D152MESC40?

A: Yes. Substitute parts with voltage ratings equal to or greater than 200 V are electrically compatible. Higher voltage ratings provide additional safety margin and do not negatively impact circuit performance. The LGG2E152MELC40 (250 V) and LGN2P152MELC40 (220 V) are both suitable for this application.

Q: What is the significance of the extended lifetime specifications in the substitute parts?

A: The LGN2P152MELC40, 381LR152M200A042, and 381LX152M200A042 all specify 3000 hours at 105°C, compared to 2000 hours for the main part. This extended lifetime indicates improved thermal stability and longer operational reliability under sustained elevated temperature conditions.

Q: Are the mechanical dimensions identical across all listed parts?

A: Yes. All substitute parts maintain identical lead spacing (0.394" / 10.00 mm), can diameter (1.378" / 35.00 mm), and seated height (1.654" / 42.00 mm). All are radial, snap-in through-hole components with identical mounting compatibility.

Q: Can I mix manufacturers in the same circuit board design?

A: Yes. Both Nichicon and Cornell Dubilier Electronics are established manufacturers of aluminum electrolytic capacitors. All listed parts meet ROHS3 compliance and REACH requirements. Mixing manufacturers is acceptable from an engineering and regulatory standpoint.

Q: What does the ±20% tolerance mean for capacitance?

A: The ±20% tolerance indicates that the actual capacitance value may vary between 1200 µF and 1800 µF. This tolerance applies uniformly across all listed parts and is standard for aluminum electrolytic capacitors in this category.

Q: Are there any ripple current differences I should consider?

A: Ripple current specifications vary among the substitute parts. The 381LR152M200A042 specifies the highest ripple current at 120 Hz (4.66 A) and 20 kHz (5.06 A). The LKX2D152MESC40 specifies 2.8 A @ 120 Hz and 4.2 A @ 50 kHz. Selection should be based on the specific ripple current requirements of your application circuit.
