450KXF56MEFC22X20 Equivalent & Substitute Parts

Part Overview

The 450KXF56MEFC22X20 is a 56 µF, 450 V aluminum electrolytic capacitor manufactured by Rubycon in the KXF series. This radial, can-style snap-in capacitor is designed for general purpose applications requiring stable performance across extended operating temperatures from -25°C to 105°C with a rated lifetime of 3000 hours at 105°C. The part is currently active in production and ROHS3 compliant. Identifying equivalent substitute parts is necessary to ensure supply chain flexibility, manage inventory optimization, and maintain design continuity when primary sources experience availability constraints.

Substitute Part Grouping Explanation

Substitute parts for the 450KXF56MEFC22X20 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Capacitance value: 56 µF (exact match required)
• Voltage rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 3000 Hrs @ 105°C (exact match required)
• Operating temperature range: -25°C ~ 105°C (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Physical dimensions: 0.866" Dia × 0.866" Height (exact match required)
• Mounting type: Through Hole (exact match required)
• Polarization: Polar (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The LGJ2W560MELZ20 manufactured by Nichicon meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the 450KXF56MEFC22X20 and LGJ2W560MELZ20 are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability, lead time, and inventory position. The LGJ2W560MELZ20 currently has higher inventory availability (1464 pcs vs. 871 pcs). Both parts meet identical electrical and mechanical specifications for general purpose applications within the specified operating temperature and voltage parameters.

Frequently Asked Questions (FAQ)

Q: Can the LGJ2W560MELZ20 be used as a direct replacement for the 450KXF56MEFC22X20?

A: Yes. Both parts share identical electrical ratings (56 µF, 450 V, ±20% tolerance), thermal specifications (3000 Hrs @ 105°C), mechanical dimensions (0.866" diameter, 0.866" height, 10.00mm lead spacing), and package configuration (Radial, Can - Snap-In, Through Hole). They are functionally interchangeable for general purpose applications.

Q: Are there differences in ripple current handling between these parts?

A: The provided specifications indicate different ripple current values at specific frequencies. The LGJ2W560MELZ20 shows higher ripple current capability at both low frequency (600 mA @ 120 Hz vs. 430 mA @ 120 Hz) and high frequency (858 mA @ 50 kHz vs. 602 mA @ 10 kHz). These differences do not affect substitution eligibility but may be relevant for applications with specific ripple current requirements.

Q: Do both parts have the same compliance certifications?

A: Yes. Both the 450KXF56MEFC22X20 and LGJ2W560MELZ20 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.22.0040.

Q: What is the lead spacing and how does it affect PCB design?

A: Both parts have identical lead spacing of 0.394" (10.00mm). This measurement determines the distance between mounting holes on the PCB. No PCB layout modifications are required when substituting between these parts.

Q: Are both parts suitable for the same temperature range?

A: Yes. Both parts operate across the identical temperature range of -25°C to 105°C with a rated lifetime of 3000 hours at the maximum temperature of 105°C.
