ERWE401LGC682MEF5M Equivalent & Substitute Parts

Part Overview

The ERWE401LGC682MEF5M is a 6800 µF, 400 V aluminum electrolytic capacitor manufactured by Chemi-Con, featuring radial, can-type construction with screw terminals. This component is classified as obsolete, with 1020 units currently in stock. The part is designed for general-purpose applications requiring high capacitance and voltage ratings in chassis-mounted configurations.

Identification of equivalent and substitute parts is necessary due to the obsolete product status of the ERWE401LGC682MEF5M. Active alternatives from the same manufacturer series provide continued availability while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the ERWE401LGC682MEF5M are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Capacitance: 6800 µF
• Voltage Rating: 400 V
• Tolerance: ±20%
• Lifetime: 2000 Hrs @ 85°C
• Operating Temperature Range: -25°C ~ 85°C
• Ripple Current @ 120 Hz: 17.3 A
• Ripple Current @ 3 kHz: 24.22 A

Mechanical Parameters (Must Match Exactly):

• Lead Spacing: 1.240" (31.50 mm)
• Case Diameter: 3.000" (76.20 mm)
• Height - Seated (Max): 6.102" (155.00 mm)
• Mounting Type: Chassis Mount
• Package / Case: Radial, Can - Screw Terminals

Compliance Parameters (Must Match):

• RoHS Compliant
• Polarization: Polar

All substitute parts listed maintain identical electrical performance, physical dimensions, and regulatory compliance with the main part number.

Engineering Selection Recommendations

ERWE401LGC682MEF5U (Direct Substitute): This part is the primary direct substitute for the obsolete ERWE401LGC682MEF5M. It maintains active product status with Chemi-Con and provides the highest inventory availability at 3300 units. All electrical specifications, mechanical dimensions, and compliance certifications are identical to the main part. The packaging designation differs (Bulk versus unspecified), but this does not affect electrical or mechanical compatibility. This part is suitable for direct replacement in all applications.

ERWE401LGN682MEF5U (Upgrade Substitute): This part provides an alternative substitute with active product status. It is functionally equivalent to both the main part and the direct substitute across all critical parameters. Inventory availability is lower at 966 units. This part may be selected when ERWE401LGC682MEF5U is unavailable or when specific packaging requirements necessitate an alternative designation.

Selection Basis:

• Both substitute parts are active products, ensuring long-term availability and supply chain continuity
• Both maintain full RoHS compliance and regulatory alignment
• Electrical performance, thermal ratings, and mechanical fit are identical across all three part numbers
• Selection between substitutes should be based on inventory availability and packaging requirements

Frequently Asked Questions (FAQ)

Q: Can ERWE401LGC682MEF5U be used as a direct replacement for ERWE401LGC682MEF5M?

A: Yes. ERWE401LGC682MEF5U is a direct substitute with identical electrical specifications (6800 µF, 400 V, ±20% tolerance), thermal ratings (2000 Hrs @ 85°C), ripple current performance (17.3 A @ 120 Hz, 24.22 A @ 3 kHz), and mechanical dimensions (3.000" diameter, 6.102" height, 1.240" lead spacing). Both parts feature screw terminal connections and chassis mount configuration. The primary difference is product status: ERWE401LGC682MEF5U is active while ERWE401LGC682MEF5M is obsolete.

Q: What is the difference between ERWE401LGC682MEF5U and ERWE401LGN682MEF5U?

A: Both parts are functionally equivalent substitutes with identical electrical and mechanical parameters. The difference lies in the part number designation (C versus N in the suffix) and inventory levels. ERWE401LGC682MEF5U has higher inventory availability (3300 units) compared to ERWE401LGN682MEF5U (966 units). Both are active products from Chemi-Con's RWE series.

Q: Are these parts interchangeable in PCB layouts and mechanical assemblies?

A: Yes. All three part numbers share identical lead spacing (1.240"), case diameter (3.000"), and maximum seated height (6.102"). They are all chassis-mount components with radial, can-type construction and screw terminals. No layout modifications or mechanical redesign is required when substituting between these parts.

Q: Do the substitute parts maintain the same operating temperature range?

A: Yes. All three parts operate across the identical temperature range of -25°C to 85°C with a rated lifetime of 2000 hours at 85°C. Thermal performance and derating characteristics are equivalent.

Q: Are there any compliance or certification differences between the parts?

A: No. All three parts are RoHS Compliant with identical REACH and ECCN classifications (EAR99). Regulatory compliance is uniform across the main part and both substitutes.

Q: What is the significance of the packaging designation difference?

A: ERWE401LGC682MEF5U is designated as Bulk packaging, while ERWE401LGC682MEF5M and ERWE401LGN682MEF5U do not have specified packaging designations in the provided data. This designation reflects distribution and handling methods but does not affect the electrical or mechanical properties of the component itself.
