Substitute Part Grouping Explanation

Substitution of the LAQ2P331MELB25 is determined by strict equivalence in the following parameters:

• Capacitance value: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package configuration: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Physical dimensions: 1.181" diameter × 1.063" height maximum (exact match required)
• Mounting type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

The substitute part LGR2E331MELB25 meets all mechanical compatibility requirements and maintains identical capacitance, tolerance, package type, lead spacing, and physical dimensions. The substitute differs in voltage rating (250 V vs. 220 V), lifetime rating (10,000 Hrs @ 105°C vs. 2,000 Hrs @ 105°C), operating temperature range (-40°C to 105°C vs. -25°C to 105°C), and ripple current specifications. These differences represent performance enhancements rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

Both the LAQ2P331MELB25 and LGR2E331MELB25 are active production parts manufactured by Nichicon and maintain ROHS3 compliance. The LAQ2P331MELB25 is specified for 220 V applications with a 2,000-hour lifetime at 105°C. The LGR2E331MELB25 provides identical mechanical and electrical compatibility with enhanced performance characteristics: higher voltage rating (250 V), extended lifetime (10,000 hours at 105°C), and wider operating temperature range (-40°C to 105°C).

Selection between these parts depends on application requirements. The LAQ2P331MELB25 is appropriate for designs operating at or below 220 V with standard lifetime expectations. The LGR2E331MELB25 is suitable for applications requiring higher voltage margin, extended service life, or operation in lower temperature environments. Both parts are suitable for direct substitution in through-hole PCB designs with 10.00 mm lead spacing and 30.00 mm diameter snap-in mounting.

Frequently Asked Questions (FAQ)

Q: Can LGR2E331MELB25 replace LAQ2P331MELB25 in existing designs?

A: Yes. Both parts share identical capacitance (330 µF), tolerance (±20%), package configuration (radial, can snap-in), lead spacing (10.00 mm), and physical dimensions (1.181" diameter × 1.063" height). PCB layouts and mechanical mounting are fully compatible. The substitute part offers enhanced voltage rating and lifetime specifications.

Q: What are the key differences between these parts?

A: The primary differences are voltage rating (220 V vs. 250 V), lifetime at 105°C (2,000 hours vs. 10,000 hours), operating temperature range (-25°C to 105°C vs. -40°C to 105°C), and high-frequency ripple current capability (1.44 A @ 10 kHz vs. 1.8 A @ 50 kHz). Mechanical and electrical compatibility remain unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both LAQ2P331MELB25 and LGR2E331MELB25 are ROHS3 compliant and meet REACH requirements.

Q: What mounting considerations apply to these snap-in capacitors?

A: Both parts are through-hole mounted with 10.00 mm lead spacing and 30.00 mm diameter snap-in cans. Mounting hardware and PCB hole patterns are identical. No design modifications are required for substitution.

Q: Which part should be selected for high-temperature or extended-life applications?

A: The LGR2E331MELB25 is specified for extended operation with 10,000-hour lifetime at 105°C and operates to -40°C minimum temperature, compared to 2,000 hours and -25°C for the LAQ2P331MELB25. Selection depends on specific application temperature and service life requirements.
