Key Parameters

Substitute Part Grouping Explanation

Substitution of the E32D401CSS682MFE3M is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute parts identified maintain identical specifications for capacitance (6800 µF), rated voltage (400 V), tolerance (±20%), ESR (25 mOhm @ 120 Hz), lifetime rating (2000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), ripple current characteristics, physical dimensions, lead spacing, and mounting configuration. All substitute parts are manufactured by Chemi-Con within the U32D series and maintain the same radial, can-mounted screw terminal package type. The primary distinction between the main part and substitutes is product status: the original part is obsolete, while the identified substitutes are active products. Compliance certifications including RoHS compliance, REACH unaffected status, and MSL rating remain consistent across all variants.

Parameter Comparison

Engineering Selection Recommendations

The E32D401CSS682MFE3M is classified as obsolete and should be replaced with an active equivalent for new designs and ongoing procurement. Both identified substitutes—E32D401CSS682MFE3U and E32D401LGN682MFE3U—are active products manufactured by Chemi-Con and maintain complete electrical and mechanical equivalence to the original part.

Selection between the two active substitutes should be based on inventory availability and procurement lead times. E32D401CSS682MFE3U currently has 945 units in stock, while E32D401LGN682MFE3U has 941 units available. Both parts carry identical RoHS compliance certification and REACH unaffected status, ensuring regulatory compliance for applications subject to environmental restrictions. The MSL rating of 1 (Unlimited) for all variants indicates no moisture sensitivity constraints during storage or handling.

For applications currently utilizing the E32D401CSS682MFE3M, direct substitution with either active equivalent is electrically and mechanically compatible without circuit modification or board redesign, provided the screw terminal connection method remains unchanged.

Frequently Asked Questions (FAQ)

Q: Can E32D401CSS682MFE3U or E32D401LGN682MFE3U be used as direct replacements for E32D401CSS682MFE3M?

A: Yes. Both substitute parts are electrically and mechanically equivalent. All critical parameters including capacitance, voltage rating, ESR, ripple current specifications, physical dimensions, lead spacing, and mounting configuration are identical. The screw terminal connection method is unchanged across all three variants.

Q: What is the difference between E32D401CSS682MFE3U and E32D401LGN682MFE3U?

A: Both parts are parametrically identical and interchangeable. The difference in part number designation reflects internal Chemi-Con manufacturing or packaging variations. All electrical specifications, physical dimensions, and performance characteristics are equivalent.

Q: Why is the original part E32D401CSS682MFE3M classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on production discontinuation. The active substitutes E32D401CSS682MFE3U and E32D401LGN682MFE3U represent the current production equivalents within the U32D series.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: No. All three variants maintain identical RoHS compliance status, REACH unaffected designation, and MSL rating of 1 (Unlimited). Regulatory compliance is maintained across all substitution options.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence across capacitance (6800 µF), rated voltage (400 V), tolerance (±20%), ESR (25 mOhm @ 120 Hz), lifetime rating (2000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), ripple current specifications, physical dimensions (3.500" diameter, 5.625" height), lead spacing (1.250"), and package type (radial, can-mounted with screw terminals).

Q: Can these capacitors be used in applications requiring higher ripple current handling?

A: The ripple current specifications are fixed at 20.58 A @ 120 Hz and 31.2816 A @ 50 kHz. Applications requiring higher ripple current capacity require selection of alternative capacitor models with higher ripple current ratings.

Q: Is the screw terminal connection method identical across all variants?

A: Yes. All three parts utilize identical radial, can-mounted screw terminal construction with 1.250" lead spacing, ensuring compatibility with existing PCB layouts and terminal connection hardware.
