Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following parameters: capacitance (270 µF), rated voltage (350 V), tolerance (±20%), polarization (polar), package type (radial, can snap-in), mounting type (through-hole), and lead spacing (10.00mm). Parts meeting these criteria are classified as direct or similar substitutes based on additional performance characteristics including operating temperature range, lifetime rating, ripple current specifications, and physical dimensions.

Direct Substitute Classification:

• LGN2V271MELB25: Identical electrical ratings with extended operating temperature range (-25°C ~ 105°C) and equivalent mechanical compatibility.

Similar Substitute Classification:

• LLS2V271MELA: Same series and electrical specifications with different physical dimensions (25.00mm diameter, 37.00mm height vs. 30.00mm diameter, 27.00mm height).
• 380LQ271M350J022: Different manufacturer (Cornell Dubilier Electronics) with equivalent electrical ratings but reduced lifetime (2000 Hrs @ 85°C) and different physical dimensions (25.00mm diameter, 32.00mm height).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the main part LLS2V271MELB. Selection between substitutes depends on application-specific requirements:

LGN2V271MELB25 is the direct substitute when identical physical dimensions and lead spacing are required. This part extends the operating temperature range to 105°C while maintaining the same 3000-hour lifetime rating at elevated temperature.

LLS2V271MELA is a similar substitute suitable for applications where a smaller diameter (25.00mm vs. 30.00mm) is acceptable but greater height (37.00mm vs. 27.00mm) can be accommodated. This part maintains identical electrical specifications and lifetime rating.

380LQ271M350J022 is a similar substitute from an alternative manufacturer suitable for applications where physical dimensions of 25.00mm diameter and 32.00mm height are compatible. This part has a reduced lifetime rating of 2000 hours at 85°C compared to the 3000-hour rating of the main part.

Frequently Asked Questions (FAQ)

Q: Can LGN2V271MELB25 be used as a direct replacement for LLS2V271MELB?

A: Yes. LGN2V271MELB25 maintains identical capacitance (270 µF), voltage rating (350 V), tolerance (±20%), lead spacing (10.00mm), and physical dimensions (30.00mm diameter, 27.00mm height). The extended operating temperature range (-25°C ~ 105°C) provides additional thermal margin without affecting compatibility.

Q: What are the physical dimension differences between substitute parts?

A: LLS2V271MELB and LGN2V271MELB25 share identical dimensions (30.00mm diameter, 27.00mm height). LLS2V271MELA has a smaller diameter (25.00mm) but greater height (37.00mm). 380LQ271M350J022 has a 25.00mm diameter and 32.00mm height. Verify PCB layout compatibility before selection.

Q: Does 380LQ271M350J022 have equivalent performance to the main part?

A: 380LQ271M350J022 matches electrical specifications but has a reduced lifetime rating of 2000 hours at 85°C versus 3000 hours for LLS2V271MELB. This part is suitable for applications where the shorter lifetime is acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of LLS2V271MELB.

Q: What is the significance of lead spacing in substitution?

A: All substitute parts maintain 10.00mm lead spacing, ensuring compatibility with PCB footprints designed for the main part. Lead spacing is a critical mechanical parameter for through-hole mounting.
