Engineering Selection Recommendations

ELXM201VSN331MP30S (Chemi-Con LXM Series, 200 V)

This substitute provides voltage uprating from 180 V to 200 V while maintaining identical capacitance, tolerance, and physical dimensions. The part is manufactured by the same supplier (Chemi-Con) within the same LXM series, ensuring design continuity. Both parts share identical ripple current ratings and operating temperature ranges. RoHS compliance is maintained. This substitute is suitable for applications where the 200 V rating provides additional design margin without requiring circuit board modifications.

LGR2D331MELZ30 (Nichicon LGR Series, 200 V)

This substitute offers voltage uprating to 200 V, extended operating temperature range (-40°C to 105°C versus -25°C to 105°C), and increased lifetime rating (10000 hours versus 7000 hours at 105°C). Physical dimensions and lead spacing remain identical. Ripple current ratings are marginally increased (1.2 A at 120 Hz and 1.8 A at 50 kHz). The part is manufactured by Nichicon and carries ROHS3 compliance. This substitute is suitable for applications requiring enhanced thermal performance, extended operational life, or broader temperature operating range.

All substitute parts maintain through-hole mounting compatibility, snap-in package configuration, and polar capacitor characteristics. Selection between substitutes depends on supply availability, manufacturer preference, and performance requirements specific to the application circuit.

Frequently Asked Questions (FAQ)

Q: Can ELXM201VSN331MP30S be used as a direct replacement for ELXM181VSN331MP30S?

A: Yes. Both parts share identical capacitance (330 µF), tolerance (±20%), physical dimensions (22.00 mm diameter, 32.00 mm height), lead spacing (10.00 mm), and mounting configuration (through-hole, radial, snap-in). The ELXM201VSN331MP30S operates at 200 V versus 180 V, providing voltage uprating. No circuit board modifications are required.

Q: What is the difference between the Chemi-Con and Nichicon substitutes?

A: Both substitutes maintain 330 µF capacitance and 200 V rating with identical physical dimensions. The Nichicon LGR2D331MELZ30 provides extended operating temperature range (-40°C to 105°C), increased lifetime (10000 hours at 105°C), and marginally higher ripple current ratings. Manufacturer selection depends on supply chain requirements and design specifications.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts (ELXM181VSN331MP30S, ELXM201VSN331MP30S, and LGR2D331MELZ30) share identical lead spacing (10.00 mm), diameter (22.00 mm), and maximum seated height (32.00 mm). All are through-hole, radial, snap-in configuration capacitors. No PCB layout modifications are necessary for substitution.

Q: Does voltage uprating affect circuit performance?

A: Voltage uprating (from 180 V to 200 V) does not degrade circuit performance. Higher voltage rating provides additional design margin and does not alter capacitance value, tolerance, or ripple current handling. The capacitor operates within its rated specifications in circuits designed for 180 V operation.

Q: Are there compliance differences between the substitutes?

A: All three parts are RoHS compliant and REACH unaffected. ELXM181VSN331MP30S and ELXM201VSN331MP30S carry RoHS compliance status. LGR2D331MELZ30 carries ROHS3 compliance status, representing the current RoHS standard. All parts carry identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications.

Q: What is the significance of the 7000-hour versus 10000-hour lifetime rating?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches specified limits. The LGR2D331MELZ30 (10000 hours) provides extended operational life compared to the 7000-hour rating of the main part and ELXM201VSN331MP30S. Selection depends on application duty cycle and maintenance intervals.

Q: Can the main part ELXM181VSN331MP30S be substituted with LGR2D331MELZ30 in existing designs?

A: Yes. The LGR2D331MELZ30 maintains all mechanical and electrical compatibility parameters. The extended temperature range (-40°C to 105°C) and increased lifetime provide performance enhancement. No design modifications are required for direct substitution in through-hole applications.
