LGU2F271MELZ Equivalent & Substitute Parts

Part Overview

The LGU2F271MELZ is a 270 µF, 315 V aluminum electrolytic capacitor manufactured by Nichicon in the LGU series. This radial, can-style snap-in capacitor is designed for general-purpose applications with a rated lifetime of 3000 hours at 105°C and an operating temperature range of -25°C to 105°C. The part is currently active in production status and ROHS3 compliant.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter tolerances for this capacitor category. Alternative models may be required due to inventory availability, performance upgrades, or specific application requirements.

Substitute Part Grouping Explanation

Substitute parts for the LGU2F271MELZ are classified based on the following substitution criteria:

Direct Equivalent (Same Electrical & Mechanical Specifications):

• LGU2F271MELB (Nichicon): Maintains identical capacitance (270 µF), voltage rating (315 V), tolerance (±20%), and operating temperature range. Lead spacing and mounting type are identical. Physical dimensions differ (1.181" Dia × 1.063" Height vs. 0.866" Dia × 1.850" Height), but both are radial snap-in packages suitable for through-hole mounting.

Upgrade Alternative (Enhanced Performance):

• 400VXH270MEFCSN22X45 (Rubycon): Provides the same capacitance (270 µF) and tolerance (±20%) with an increased voltage rating of 400 V (versus 315 V). Lifetime is extended to 5000 hours at 105°C (versus 3000 hours). Physical dimensions match the main part (0.866" Dia × 1.850" Height). Lead spacing and mounting type are identical. This part functions as a performance upgrade while maintaining mechanical compatibility.

All substitute parts maintain the same polarization (polar), package style (radial snap-in), and through-hole mounting configuration. All are ROHS3 compliant and REACH unaffected.

Engineering Selection Recommendations

LGU2F271MELB Selection Criteria: The LGU2F271MELB is a direct equivalent suitable for applications where inventory availability of the primary part is limited. Both parts are manufactured by Nichicon, maintain identical electrical specifications (270 µF, 315 V, ±20% tolerance), and share the same operating temperature range and lifetime rating. The primary difference is physical dimension; the LGU2F271MELB has a larger diameter (1.181" vs. 0.866") but reduced height (1.063" vs. 1.850"). This part is appropriate only when PCB layout accommodates the larger radial footprint. Both parts are ROHS3 compliant and active in production.

400VXH270MEFCSN22X45 Selection Criteria: The 400VXH270MEFCSN22X45 is an upgrade alternative manufactured by Rubycon. It maintains identical capacitance, tolerance, and physical dimensions to the main part, ensuring direct mechanical compatibility. The upgrade provides increased voltage headroom (400 V vs. 315 V) and extended lifetime (5000 hours vs. 3000 hours at 105°C). This part is suitable for applications requiring enhanced reliability or operation in higher voltage environments while maintaining the same form factor. The part is ROHS3 compliant and active in production.

All three parts are suitable for general-purpose applications and maintain compliance with applicable regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can LGU2F271MELB be used as a direct replacement for LGU2F271MELZ? A: Yes, the LGU2F271MELB is electrically equivalent with identical capacitance (270 µF), voltage rating (315 V), tolerance (±20%), and operating temperature range. However, physical dimensions differ; the LGU2F271MELB is larger in diameter (1.181" vs. 0.866") but shorter in height (1.063" vs. 1.850"). Verify PCB layout compatibility before substitution.

Q: What is the advantage of using 400VXH270MEFCSN22X45 over LGU2F271MELZ? A: The 400VXH270MEFCSN22X45 provides two performance enhancements: increased voltage rating (400 V vs. 315 V) and extended lifetime (5000 hours vs. 3000 hours at 105°C). Physical dimensions and lead spacing are identical, ensuring direct mechanical compatibility. This part is suitable for applications requiring higher voltage margins or longer operational life.

Q: Are all three parts mechanically compatible with the same PCB footprint? A: LGU2F271MELZ and 400VXH270MEFCSN22X45 share identical physical dimensions and lead spacing, making them directly interchangeable on the PCB. LGU2F271MELB has different dimensions and requires layout verification before use.

Q: Do all substitute parts meet the same compliance standards? A: Yes, all three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All are active in production status.

Q: What is the lead spacing for all three parts? A: All three parts have identical lead spacing of 0.394" (10.00mm), supporting through-hole mounting on standard PCB layouts.

Q: Can 400VXH270MEFCSN22X45 be used in applications designed for 315 V operation? A: Yes. The 400VXH270MEFCSN22X45 has a higher voltage rating (400 V) and will operate safely in circuits designed for 315 V. The higher voltage rating provides additional safety margin without affecting circuit performance.
