Key Parameters

Substitute Part Grouping Explanation

Substitution of the 380LX331M180H012 is determined by strict adherence to the following parameters:

Critical Compatibility Parameters:

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Case Diameter: 22.00 mm (exact match required)
• Height - Seated (Max): 27.00 mm (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Allowable Upgrade Parameters:

• Voltage - Rated: May be equal to or greater than 180 V
• Operating Temperature Range: May extend to higher maximum temperatures
• Lifetime @ Temperature: May be equal to or greater than 3000 Hrs @ 85°C
• ESR: May be equal to or lower than 603 mOhm @ 120Hz

All three substitute parts meet these criteria with identical mechanical dimensions and electrical base specifications while offering enhanced voltage ratings and thermal performance characteristics.

Engineering Selection Recommendations

B43508A2337M000 (EPCOS - TDK Electronics)

This substitute provides a 200 V rated voltage with improved ESR performance of 350 mOhm @ 100Hz compared to the main part's 603 mOhm @ 120Hz. The extended operating temperature range to 105°C and higher inventory availability (2195 units) support applications requiring enhanced thermal stability. ROHS3 compliance and REACH unaffected status maintain regulatory alignment with the original component.

LGN2D331MELZ25 (Nichicon)

This substitute maintains 200 V voltage rating with extended operating temperature to 105°C. Ripple current specifications of 1.2 A @ 120 Hz and 1.8 A @ 50 kHz are provided. ROHS3 compliance and active product status ensure continued availability. Inventory of 1081 units supports component procurement requirements.

LGN2P331MELZ25 (Nichicon)

This substitute offers the highest voltage rating at 220 V with extended operating temperature to 105°C. Ripple current specifications of 1.26 A @ 120 Hz and 1.89 A @ 50 kHz provide enhanced current handling capability. ROHS3 compliance and 1278 units in inventory support long-term supply chain requirements.

All three substitutes maintain identical mechanical compatibility and through-hole mounting configuration, enabling direct board-level replacement without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the B43508A2337M000 directly replace the 380LX331M180H012 on existing PCBs?

A: Yes. Both components share identical lead spacing (10.00 mm), case diameter (22.00 mm), and seated height (27.00 mm). The snap-in radial can configuration and through-hole mounting type are identical, enabling direct replacement without PCB modification.

Q: What is the significance of the voltage rating upgrade from 180 V to 200 V or 220 V?

A: Higher voltage ratings provide increased safety margin in applications operating near the original component's rated voltage. The substitute parts maintain the same capacitance and tolerance specifications while supporting higher voltage stress conditions. This upgrade does not affect circuit functionality in applications operating below the original 180 V specification.

Q: Are the substitute parts compatible with the same circuit board footprint?

A: Yes. All substitute parts maintain the critical mechanical parameters: 10.00 mm lead spacing, 22.00 mm case diameter, and 27.00 mm maximum seated height. The radial, can snap-in package configuration is identical across all parts, ensuring footprint compatibility.

Q: How do the ESR specifications compare between the main part and substitutes?

A: The main part specifies 603 mOhm @ 120Hz. The B43508A2337M000 provides improved ESR of 350 mOhm @ 100Hz. The Nichicon LGN2D331MELZ25 and LGN2P331MELZ25 do not specify ESR values in the provided data. ESR performance affects ripple current handling and thermal characteristics in high-frequency applications.

Q: What is the difference between the LGN2D331MELZ25 and LGN2P331MELZ25?

A: Both are Nichicon LGN series components with identical mechanical dimensions and 330 µF capacitance. The primary difference is voltage rating: LGN2D331MELZ25 is rated 200 V, while LGN2P331MELZ25 is rated 220 V. Both support extended operating temperature to 105°C and provide identical lead spacing and case dimensions.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. All three substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original 380LX331M180H012 component.

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

A: Yes, within the constraints of the application's voltage requirements. All parts maintain identical capacitance (330 µF), tolerance (±20%), lead spacing (10.00 mm), and mechanical dimensions. Component selection should be based on the application's maximum operating voltage: 180 V or below for the main part, 200 V or below for B43508A2337M000 and LGN2D331MELZ25, and 220 V or below for LGN2P331MELZ25.
