Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAQ2P331MELZ40 is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Size / Dimension: 0.866" Dia (22.00 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)
• Polarization: Polar (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 220 V
• Lifetime @ Temperature: May be equal to or greater than 2000 Hrs @ 105°C
• Operating Temperature Range: May be equal to or extend beyond -25°C ~ 105°C
• Ripple Current: May be equal to or greater than specified values
• RoHS Status: Must maintain ROHS3 Compliance or equivalent
• Product Status: Must be Active

The LGR2E331MELZ40 qualifies as a direct substitute based on these criteria, offering enhanced voltage rating and extended operational lifetime while maintaining identical mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the LAQ2P331MELZ40 and LGR2E331MELZ40 are Active products manufactured by Nichicon and maintain ROHS3 compliance. The LGR2E331MELZ40 provides enhanced performance characteristics including a 250 V rated voltage (versus 220 V), extended operational lifetime of 10000 Hrs @ 105°C (versus 2000 Hrs), and expanded operating temperature range to -40°C (versus -25°C minimum). These enhancements do not compromise mechanical compatibility or electrical performance in applications designed for the LAQ2P331MELZ40.

Selection between these parts should be based on application-specific requirements: the LAQ2P331MELZ40 is suitable for standard general-purpose applications with standard thermal and voltage margins, while the LGR2E331MELZ40 is appropriate for applications requiring extended service life, enhanced temperature tolerance, or higher voltage headroom.

Frequently Asked Questions (FAQ)

Q: Can the LGR2E331MELZ40 be used as a direct replacement for the LAQ2P331MELZ40?

A: Yes. The LGR2E331MELZ40 maintains identical mechanical dimensions, lead spacing, mounting configuration, and capacitance specifications. The higher voltage rating and extended lifetime represent performance enhancements that do not create compatibility issues in circuits designed for the LAQ2P331MELZ40.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (250 V versus 220 V), operational lifetime (10000 Hrs versus 2000 Hrs @ 105°C), and minimum operating temperature (-40°C versus -25°C). All other electrical and mechanical parameters remain identical.

Q: Are there any circuit design considerations when substituting the LGR2E331MELZ40 for the LAQ2P331MELZ40?

A: No design modifications are required. The substitute part operates within the same electrical parameters and physical constraints as the original part. The enhanced voltage rating and lifetime provide additional design margin without requiring circuit alterations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LAQ2P331MELZ40 and LGR2E331MELZ40 are ROHS3 compliant and maintain identical regulatory status.

Q: What is the significance of the snap-in package configuration?

A: The snap-in package indicates a through-hole mounting style with mechanical retention features. Both parts utilize identical snap-in configurations with matching lead spacing (10.00 mm) and physical dimensions, ensuring mechanical interchangeability on PCBs designed for either component.
