LAQ2P331MELA30 Equivalent & Substitute Parts

Part Overview

The LAQ2P331MELA30 is a 330 µF, 220 V aluminum electrolytic capacitor manufactured by Nichicon in the LAQ series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring through-hole mounting with a 2000-hour lifetime rating at 105°C. The part is currently active in production. Equivalent and substitute parts may be required due to inventory availability, extended operational requirements, or design optimization needs while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LAQ2P331MELA30 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Capacitance: 330 µF
• Tolerance: ±20%
• Polarization: Polar
• Package Type: Radial, Can - Snap-In
• Mounting Type: Through Hole
• Lead Spacing: 0.394" (10.00 mm)
• Case Diameter: 0.984" (25.00 mm)
• Height (Max): 1.260" (32.00 mm)

Allowable Variations:

• Voltage Rating: May be equal to or greater than 220 V
• Operating Temperature Range: May be equal to or wider than -25°C to 105°C
• Lifetime @ 105°C: May be equal to or greater than 2000 Hrs
• Manufacturer: Different manufacturer acceptable if all parameters align

The substitute part B43504C2337M000 meets all critical parameters with allowable variations in voltage rating (250 V), operating temperature range (-40°C to 105°C), and lifetime (3000 Hrs @ 105°C).

Parameter Comparison

Engineering Selection Recommendations

The B43504C2337M000 is electrically and mechanically compatible with the LAQ2P331MELA30 for direct substitution in existing designs. The substitute part provides higher voltage rating (250 V vs. 220 V) and extended lifetime (3000 Hrs vs. 2000 Hrs at 105°C), making it suitable for applications requiring enhanced reliability margins.

The B43504C2337M000 carries a "Not For New Designs" product status, indicating it is available for replacement and legacy applications but should not be selected for new product development. For new designs, the LAQ2P331MELA30 (Active status) is the preferred choice.

Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can B43504C2337M000 be used as a direct replacement for LAQ2P331MELA30?

A: Yes. Both parts share identical capacitance (330 µF), tolerance (±20%), package type (Radial, Can - Snap-In), mounting type (Through Hole), and physical dimensions (lead spacing, case diameter, and height). The substitute has higher voltage rating and longer lifetime, which are allowable variations.

Q: What is the difference in voltage rating between these parts?

A: The LAQ2P331MELA30 is rated at 220 V, while the B43504C2337M000 is rated at 250 V. The higher voltage rating of the substitute provides additional safety margin in applications operating at or below 220 V.

Q: Are there differences in operating temperature range?

A: Yes. The LAQ2P331MELA30 operates from -25°C to 105°C, while the B43504C2337M000 operates from -40°C to 105°C. The substitute supports a wider lower temperature range, suitable for applications requiring extended cold-temperature performance.

Q: What does "Not For New Designs" mean for the B43504C2337M000?

A: This product status indicates the part is available for replacement, repair, and legacy applications but is not recommended for new product development. For new designs, select the LAQ2P331MELA30 (Active status).

Q: Are both parts physically interchangeable on the PCB?

A: Yes. Both parts have identical lead spacing (0.394" / 10.00 mm), case diameter (0.984" / 25.00 mm), and maximum height (1.260" / 32.00 mm), ensuring direct mechanical compatibility with existing through-hole snap-in footprints.

Q: Do both parts meet current compliance standards?

A: Yes. Both the LAQ2P331MELA30 and B43504C2337M000 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
