Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by strict equivalence of electrical and mechanical parameters. The ELXM251VSN331MP40S and its identified substitute LGR2E331MELZ40 share identical specifications across all critical selection criteria:

Electrical Parameters (Must Match):

• Capacitance: 330 µF
• Voltage Rating: 250 V
• Tolerance: ±20%
• Polarization: Polar

Mechanical Parameters (Must Match):

• Package Type: Radial, Can - Snap-In
• Lead Spacing: 0.394" (10.00 mm)
• Diameter: 0.866" (22.00 mm)
• Height: 1.654" (42.00 mm)
• Mounting Type: Through Hole

Both parts are rated for general-purpose applications and maintain RoHS compliance. The substitute part is qualified for direct replacement based on dimensional and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ELXM251VSN331MP40S and LGR2E331MELZ40 are active production parts with full regulatory compliance. Selection between these parts is based on the following criteria:

ELXM251VSN331MP40S (Chemi-Con LXM Series):

• Primary choice when Chemi-Con supply is available
• RoHS Compliant certification
• 7000 hour lifetime rating at 105°C
• Operating temperature range: -25°C to 105°C

LGR2E331MELZ40 (Nichicon LGR Series):

• Direct substitute when Chemi-Con part is unavailable
• ROHS3 Compliant certification (enhanced RoHS standard)
• Extended 10000 hour lifetime rating at 105°C
• Wider operating temperature range: -40°C to 105°C
• Ripple current specifications within 1.6% of primary part

Both parts are suitable for general-purpose applications and maintain identical footprint and electrical ratings. The Nichicon substitute offers extended temperature range and longer operational lifetime, making it suitable for applications requiring enhanced reliability margins.

Frequently Asked Questions (FAQ)

Q: Can LGR2E331MELZ40 be used as a direct replacement for ELXM251VSN331MP40S?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (250 V), tolerance (±20%), and mechanical dimensions (0.866" diameter, 1.654" height, 10.00 mm lead spacing). The snap-in radial can package and through-hole mounting type are identical, ensuring PCB compatibility without layout modifications.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (Chemi-Con vs. Nichicon), lifetime rating (7000 hrs vs. 10000 hrs at 105°C), operating temperature range (-25°C to 105°C vs. -40°C to 105°C), and RoHS certification level (RoHS Compliant vs. ROHS3 Compliant). Ripple current specifications are equivalent within normal manufacturing tolerances.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts have identical lead spacing (10.00 mm) and package dimensions. No PCB modifications or re-qualification is required for substitution.

Q: Which part should be selected for applications requiring extended temperature operation?

A: The LGR2E331MELZ40 supports operation down to -40°C, compared to -25°C for the ELXM251VSN331MP40S. For applications requiring the extended lower temperature range, the Nichicon part is the appropriate selection.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both parts are REACH Unaffected and carry current RoHS certifications (RoHS Compliant and ROHS3 Compliant respectively). Both are suitable for applications subject to environmental compliance requirements.
