Parameter Comparison

Engineering Selection Recommendations

Both the LGU2E271MELY and 381LR271M250H022 maintain Active product status with identical RoHS3 and REACH compliance certifications. The 381LR271M250H022 demonstrates superior ripple current handling at 1.42 A @ 120 Hz compared to the LGU2E271MELY at 1.1 A @ 120 Hz, while maintaining all core electrical and mechanical specifications. The substitute part features a documented ESR value of 737 mOhm @ 120 Hz, providing additional performance transparency. Both components are qualified for general-purpose applications across the full -40°C to 105°C operating temperature range with equivalent 3000-hour lifetime ratings at 105°C. Selection between these parts should be based on supply availability and inventory management requirements, as both satisfy identical functional and compliance criteria.

Frequently Asked Questions (FAQ)

Q: Can the 381LR271M250H022 be used as a direct replacement for the LGU2E271MELY in existing designs?

A: Yes. Both parts share identical capacitance (270 µF), voltage rating (250 V), tolerance (±20%), polarization (Polar), package type (Radial, Can - Snap-In), mounting configuration (Through Hole), lead spacing (10.00mm), and operating temperature range (-40°C ~ 105°C). Mechanical and electrical compatibility is confirmed.

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

A: The LGU2E271MELY has a diameter of 0.787" (20.00mm) and height of 1.378" (35.00mm). The 381LR271M250H022 has a diameter of 0.866" (22.00mm) and height of 1.260" (32.00mm). Both maintain the same 0.394" (10.00mm) lead spacing. PCB layout verification is required to confirm fit within available board space.

Q: Are there compliance or certification differences between these parts?

A: Both parts are RoHS3 Compliant and REACH Unaffected. No compliance differentiation exists between the LGU2E271MELY and 381LR271M250H022.

Q: How do the ripple current ratings compare?

A: The LGU2E271MELY is rated for 1.1 A @ 120 Hz and 1.65 A @ 50 kHz. The 381LR271M250H022 is rated for 1.42 A @ 120 Hz and 2.03 A @ 20 kHz. The substitute part provides higher ripple current capacity at low frequencies.
