Engineering Selection Recommendations

Direct Equivalents (Nichicon LGN and LQS Series): LGN2V271MELA35 and LQS2V271MELA35 are direct functional equivalents to LLS2V271MELA. Both parts maintain identical physical dimensions, lead spacing, and package configuration. These parts are rated for extended operating temperature range (-25°C to 105°C) and provide equivalent 3000-hour lifetime ratings at their respective temperature specifications. Both are ROHS3 compliant and REACH unaffected. Selection between these Nichicon alternatives depends on thermal environment requirements and ripple current capacity needs.

Similar Alternative (Nichicon LLS2V271MELB): LLS2V271MELB shares the same series designation and thermal rating as the primary part but features different physical dimensions (1.181" diameter, 1.063" height versus 0.984" diameter, 1.457" height). This part is suitable only when PCB layout accommodates the larger diameter and reduced height profile. Lead spacing remains compatible at 0.394" (10.00 mm).

Similar Alternatives (Cornell Dubilier 380LQ Series): 380LQ271M350H042 and 380LQ271M350J022 are cross-manufacturer alternatives from Cornell Dubilier Electronics. Both maintain the required 270 µF, 350 V specifications and snap-in package configuration. These parts operate at 2000-hour lifetime rating at 85°C, which is lower than the Nichicon primary part. Physical dimensions differ: 380LQ271M350H042 features 0.866" diameter and 1.654" height; 380LQ271M350J022 features 0.984" diameter and 1.260" height. Both are ROHS3 compliant and REACH unaffected. ESR is specified at 737 mOhm @ 120 Hz for both CDE parts.

All listed parts maintain Active product status and are suitable for general-purpose applications where the specified electrical and mechanical parameters are compatible with circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can LGN2V271MELA35 or LQS2V271MELA35 be used as direct replacements for LLS2V271MELA?

A: Yes. Both parts are direct functional equivalents. They maintain identical capacitance (270 µF), voltage rating (350 V), tolerance (±20%), physical dimensions, lead spacing (0.394" / 10.00 mm), and package type (Radial, Can - Snap-In). The primary difference is the extended operating temperature range (-25°C to 105°C versus -25°C to 85°C) and corresponding thermal lifetime rating (3000 Hrs @ 105°C). PCB layout and mounting compatibility are identical.

Q: What is the key difference between LLS2V271MELA and LLS2V271MELB?

A: Both parts share the same series designation, capacitance, voltage rating, and thermal specifications. The primary difference is physical dimensions: LLS2V271MELB has a larger diameter (1.181" versus 0.984") but reduced height (1.063" versus 1.457"). Lead spacing remains identical at 0.394" (10.00 mm). Selection depends on available PCB space and mounting constraints.

Q: Are Cornell Dubilier 380LQ parts suitable replacements?

A: 380LQ271M350H042 and 380LQ271M350J022 are compatible alternatives that maintain the required 270 µF, 350 V specifications and snap-in package configuration. However, these parts have a lower lifetime rating (2000 Hrs @ 85°C versus 3000 Hrs @ 85°C for Nichicon parts). Physical dimensions differ between the two CDE options. Selection requires confirmation that the reduced lifetime rating is acceptable for the application.

Q: Does lead spacing remain consistent across all substitute parts?

A: Yes. All listed parts maintain 0.394" (10.00 mm) lead spacing, ensuring PCB footprint compatibility. Physical diameter and height vary between parts, which may affect mounting clearance and thermal management considerations.

Q: What compliance certifications apply to all substitute parts?

A: All listed parts are ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level (MSL) is Not Applicable for Nichicon parts and MSL 1 (Unlimited) for Cornell Dubilier parts.

Q: How do ripple current specifications differ between alternatives?

A: LLS2V271MELA and LLS2V271MELB (Nichicon) provide higher ripple current capacity (1.73–1.8 A @ 120 Hz, 2.4739–2.574 A @ 50 kHz) compared to LGN2V271MELA35 and LQS2V271MELA35 (1.1 A @ 120 Hz, 1.573 A @ 50 kHz). Cornell Dubilier 380LQ parts provide 1.66 A @ 120 Hz and 2.32 A @ 20 kHz. Selection depends on circuit ripple current requirements at specified frequencies.
