Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for aluminum electrolytic capacitors is determined by strict electrical and mechanical parameter matching. The following criteria establish whether a component qualifies as an equivalent or direct substitute:

Primary Electrical Parameters:

• Capacitance value: Must match at 1800 µF
• Tolerance specification: Must match at ±20%
• Rated voltage: Must match at 200 V
• Equivalent series resistance: Component-specific; lower or equal values indicate equivalent or superior performance characteristics

Secondary Performance Parameters:

• Lifetime @ temperature: Equal or extended lifetime indicates equivalent or upgraded capability
• Operating temperature range: Must encompass or match -40°C ~ 85°C
• Ripple current ratings: Equal or higher values indicate equivalent or superior performance

Mechanical Parameters:

• Lead spacing: Must match at 0.394" (10.00 mm) for direct PCB compatibility
• Size / dimension (diameter): Must match at 1.378" (35.00 mm)
• Height - seated (max): Height tolerance within mechanical envelope constraints
• Mounting type: Must match through-hole configuration
• Package / case: Must match radial, can-type snap-in design

Compliance Parameters:

• RoHS3 compliance required
• Moisture sensitivity level compatibility

The substitute parts listed below satisfy these parameter requirements and maintain full electrical and mechanical interchangeability within the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

Both 380LX182M200A452 and LLS2D182MELC qualify as functional equivalents and direct substitutes for LPX182M200H4P3 based on electrical and mechanical parameter compatibility.

380LX182M200A452 (Cornell Dubilier Electronics, 380LX Series)

This component maintains identical electrical specifications to the primary part with identical ESR values and matching capacitance, tolerance, and voltage ratings. The key differentiator is the extended operational lifetime of 3000 Hrs @ 85°C compared to the 1000 Hrs @ 85°C lifetime of LPX182M200H4P3. The slightly increased maximum height of 1.850" (47.00 mm) versus 1.772" (45.00 mm) requires verification within the target application's spatial constraints. Enhanced ripple current capability at high frequency (6 A @ 20 kHz) supports designs with elevated thermal stress requirements. ROHS3 compliance and active product status confirm regulatory and supply chain viability.

LLS2D182MELC (Nichicon, LLS Series)

This Nichicon component provides electrical equivalence with a 3000 Hrs @ 85°C operational lifetime. Lead spacing and can diameter match exactly. The more compact seated height of 1.575" (40.00 mm) offers superior spatial compatibility within confined mounting envelopes. Enhanced ripple current capacity (6.885 A @ 50 kHz) exceeds the primary part's specifications. ESR data is not specified in technical documentation. ROHS3 compliance and not-applicable MSL classification (standard for this manufacturer's product line) confirm environmental compliance. The exceptionally high inventory level of 273,982 units indicates supply chain security and rapid availability.

Both substitutes are classified as Active products with ROHS3 compliance, supporting deployment in regulated applications requiring full environmental compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can 380LX182M200A452 replace LPX182M200H4P3 in existing PCB layouts?

A: Yes, with spatial consideration. The core electrical parameters (capacitance, voltage, ESR) and lead spacing match exactly, ensuring functional compatibility. The increased maximum height of 1.850" (47.00 mm) compared to 1.772" (45.00 mm) requires verification against the PCB enclosure clearance. The extended 3000 Hrs @ 85°C lifetime represents enhanced reliability compared to the original 1000 Hrs specification.

Q: Can LLS2D182MELC replace LPX182M200H4P3 in existing PCB layouts?

A: Yes, with confirmed spatial advantage. Identical electrical parameters, matching lead spacing and can diameter, combined with a more compact height of 1.575" (40.00 mm), offer superior fit within height-restricted applications. Enhanced ripple current ratings provide additional design margin for thermal performance.

Q: Are there differences in ESR (Equivalent Series Resistance) between these substitutes?

A: LPX182M200H4P3 and 380LX182M200A452 maintain identical ESR specifications at 111 mOhm @ 120 Hz. LLS2D182MELC does not specify ESR in available technical documentation, though the higher ripple current ratings suggest comparable or superior internal impedance characteristics typical of Nichicon components in this category.

Q: What is the significance of the operational lifetime difference (1000 Hrs vs. 3000 Hrs @ 85°C)?

A: Operational lifetime at elevated temperature is a primary reliability indicator for aluminum electrolytic capacitors. The 380LX182M200A452 and LLS2D182MELC both offer 3000 Hrs @ 85°C, indicating a three-fold improvement in accelerated aging performance compared to the LPX182M200H4P3 specification of 1000 Hrs @ 85°C. This translates to extended field life and reduced maintenance requirements in applications operating near rated voltage and temperature limits.

Q: How do ripple current ratings affect component selection?

A: Ripple current capacity determines the maximum AC current component a capacitor can withstand at specified frequencies without excessive temperature rise. Both substitute parts exceed LPX182M200H4P3 ripple current specifications across frequency ranges, providing additional design margin. LLS2D182MELC demonstrates 6.885 A @ 50 kHz versus the primary part's 4.4 A @ 50 kHz, representing 56% higher capacity at this frequency.

Q: Are all three parts RoHS3 compliant?

A: Yes. LPX182M200H4P3, 380LX182M200A452, and LLS2D182MELC are all RoHS3 compliant, confirming compliance with directive 2011/65/EU and supporting unrestricted deployment in regulated markets.

Q: What is the difference in inventory availability?

A: LPX182M200H4P3 shows 1,060 units in stock. 380LX182M200A452 provides 2,321 units. LLS2D182MELC demonstrates substantially higher availability at 273,982 units in stock, offering significant supply chain security and rapid procurement advantage.
