Parameter Comparison

Engineering Selection Recommendations

All three parts—LGJ2D271MELB, LGU2D271MELZ, and 381LX271M200J012—are electrically equivalent and mechanically compatible for through-hole snap-in applications. All parts are Active in product status, ROHS3 compliant, and REACH unaffected, meeting current regulatory requirements.

Physical dimensions vary among the three parts. The LGJ2D271MELB has a larger diameter (1.181" / 30.00 mm) and shorter height (0.866" / 22.00 mm). The LGU2D271MELZ has a smaller diameter (0.866" / 22.00 mm) and taller height (0.984" / 25.00 mm). The 381LX271M200J012 has an intermediate diameter (0.984" / 25.00 mm) and the greatest height (1.063" / 27.00 mm). PCB layout and available mounting space determine which physical configuration is suitable for a given application.

Ripple current performance at 120 Hz is slightly higher in the LGU2D271MELZ (1.1 A) and 381LX271M200J012 (1.1 A) compared to the LGJ2D271MELB (1.05 A). This difference is within normal manufacturing variation for this capacitor category and does not affect substitution eligibility.

Frequently Asked Questions (FAQ)

Q: Can LGU2D271MELZ be used as a direct replacement for LGJ2D271MELB?

A: Yes. Both parts share identical electrical specifications: 270 µF capacitance, 200 V voltage rating, ±20% tolerance, 3000 hours lifetime at 105°C, and -40°C to 105°C operating temperature range. Both are polar, through-hole, snap-in radial cans with 0.394" (10.00 mm) lead spacing. The primary difference is physical size. Verify that PCB layout accommodates the LGU2D271MELZ dimensions (0.866" diameter × 0.984" height) before substitution.

Q: Can 381LX271M200J012 be used as a direct replacement for LGJ2D271MELB?

A: Yes. The 381LX271M200J012 meets all electrical and mechanical substitution criteria. It is manufactured by Cornell Dubilier Electronics and shares the same capacitance, voltage, tolerance, lifetime, and operating temperature specifications. Physical dimensions differ: 0.984" diameter × 1.063" height. Confirm PCB clearance before installation.

Q: What are the key differences between these three parts?

A: All three parts are electrically identical. Differences are limited to physical dimensions and ripple current performance. The LGJ2D271MELB is the largest in diameter but shortest in height. The LGU2D271MELZ is the smallest in diameter but taller. The 381LX271M200J012 is intermediate in diameter and tallest overall. Ripple current at 120 Hz is 1.05 A for the LGJ2D271MELB and 1.1 A for both substitute parts.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the lead spacing for all three parts?

A: All three parts have identical lead spacing of 0.394" (10.00 mm), ensuring compatibility with standard through-hole PCB footprints designed for this spacing.

Q: Can physical size differences affect circuit performance?

A: Physical size differences do not affect electrical performance. Capacitance, voltage rating, tolerance, and lifetime specifications are identical across all three parts. Size differences may affect PCB layout feasibility and thermal management in space-constrained applications. Verify available mounting space before selecting a substitute.
