LGJ2F680MELZ Equivalent & Substitute Parts

Part Overview

The LGJ2F680MELZ is a 68 µF, 315 V aluminum electrolytic capacitor manufactured by Nichicon in the LGJ 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 with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when equivalent capacitance and tolerance are maintained while other electrical parameters may be upgraded or adjusted to meet specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the LGJ2F680MELZ and LGJ2G680MELZ20 are active production parts with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current applications. The LGJ2G680MELZ20 provides a higher voltage rating (400 V versus 315 V) and increased ripple current capacity at both low and high frequencies, making it suitable for applications requiring enhanced electrical performance margins. Selection between these parts depends on the specific voltage and ripple current requirements of the target application. Both parts maintain identical mechanical compatibility, physical dimensions, and thermal characteristics, allowing direct substitution in through-hole PCB designs without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the LGJ2G680MELZ20 be used as a direct replacement for the LGJ2F680MELZ?

A: Yes. Both parts share identical capacitance (68 µF), tolerance (±20%), physical dimensions (0.866" diameter × 0.866" height), lead spacing (10.00mm), and mounting configuration (radial, can-style snap-in through-hole). The substitute part is mechanically and electrically compatible for direct PCB substitution.

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

A: The primary differences are the rated voltage (315 V for LGJ2F680MELZ versus 400 V for LGJ2G680MELZ20) and ripple current capacity. The substitute part provides higher voltage rating and increased ripple current handling at both 120 Hz (620 mA versus 450 mA) and 50 kHz (886.6 mA specified for substitute only).

Q: Are there any thermal or operating temperature differences?

A: No. Both parts operate across the identical temperature range of -25°C to 105°C and maintain the same lifetime specification of 3000 hours at 105°C.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the LGJ2F680MELZ and LGJ2G680MELZ20 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the lead spacing and can these parts fit existing PCB designs?

A: Both parts have identical lead spacing of 0.394" (10.00mm) and physical dimensions of 0.866" diameter with 0.866" seated height. They are fully compatible with PCB designs originally specified for either part number.
