LGU2F561MELB Equivalent & Substitute Parts

Part Overview

The LGU2F561MELB is a 560 µF, 315 V aluminum electrolytic capacitor manufactured by Nichicon in a radial, can snap-in configuration. This component is designed for general-purpose applications requiring high-capacitance energy storage in compact form factors. The part maintains Active product status with 92,600 units in current inventory. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to supply constraints, application voltage headroom needs, or extended lifetime requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the LGU2F561MELB is determined by strict adherence to the following criteria:

Primary Matching Parameters:

Capacitance: 560 µF (exact match required)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.394" (10.00mm) (exact match required)
Case Diameter: 1.181" (30.00mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Polarization: Polar (exact match required)

Allowable Variation Parameters:

Voltage Rating: Equal to or greater than 315 V
Height (Seated Max): Equal to or less than 1.870" (47.50mm)
Lifetime @ Temperature: Equal to or greater than 3000 Hrs @ 105°C
Operating Temperature Range: Equal to or broader than -25°C ~ 105°C
RoHS Status: ROHS3 Compliant (required)

All three identified substitute parts meet these criteria and are therefore electrically and mechanically compatible with the LGU2F561MELB.

Engineering Selection Recommendations

All three substitute parts maintain Active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the LGU2F561MELB.

450MXK560MEFC30X45 (Rubycon MXK Series): Offers elevated voltage rating of 450 V, providing 135 V margin above the original specification. Maintains identical physical dimensions and 3000-hour lifetime rating. Suitable for applications requiring enhanced voltage headroom.

B43642A9567M000 (EPCOS - TDK B43642 Series): Provides 400 V voltage rating with 85 V margin. Extends operating temperature range to -40°C lower bound. Maintains 3000-hour lifetime and identical mechanical footprint. ESR specification of 180 mOhm @ 100 Hz is provided.

ELXS401VSN561MR45S (Chemi-Con LXS Series): Delivers 400 V voltage rating with 85 V margin and extended 5000-hour lifetime at 105°C, representing 67% longer operational life than the original part. Height specification of 1.870" (47.50mm) remains within acceptable tolerance for snap-in mounting. Suitable for applications prioritizing extended service life.

Frequently Asked Questions (FAQ)

Q: Can these substitute parts be used interchangeably with the LGU2F561MELB?

A: Yes, all three substitute parts are mechanically and electrically compatible. They share identical capacitance (560 µF), tolerance (±20%), lead spacing (10.00mm), case diameter (30.00mm), and mounting configuration (radial, can snap-in through-hole). Physical height variations remain within acceptable limits for PCB assembly.

Q: What is the significance of higher voltage ratings in the substitute parts?

A: The substitute parts rated at 400 V and 450 V provide voltage margin above the original 315 V specification. This margin protects against transient overvoltage conditions and extends component reliability in applications subject to voltage stress. Higher voltage ratings do not alter capacitance or physical compatibility.

Q: How does the extended lifetime of ELXS401VSN561MR45S affect selection?

A: The ELXS401VSN561MR45S provides 5000 hours at 105°C compared to 3000 hours for the original part. This extended lifetime applies only to thermal aging at the specified temperature. Selection should be based on application duty cycle and expected service life requirements.

Q: Are there packaging differences between these parts?

A: The LGU2F561MELB is supplied in Bulk packaging, while 450MXK560MEFC30X45 is supplied in Tray packaging. B43642A9567M000 and ELXS401VSN561MR45S are supplied in Bulk packaging. Packaging format does not affect component performance or PCB compatibility.

Q: Do all parts meet the same compliance standards?

A: All four parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements. All carry EAR99 ECCN classification and 8532.22.0040 HTSUS code.
