Equivalent & Substitute Parts for E36D401CSS472MEA5M

Part Overview

The E36D401CSS472MEA5M is a 4700 µF, 400 V aluminum electrolytic capacitor manufactured by Chemi-Con, featuring screw terminals and radial can packaging. This component is classified as obsolete, indicating that direct procurement of this specific part number is no longer supported by the manufacturer. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, making it suitable for general-purpose applications requiring high-capacitance energy storage in industrial and power conversion circuits.

Due to its obsolete status, equivalent substitute parts from both Chemi-Con and alternative manufacturers are necessary to maintain design continuity and ensure component availability for repair, replacement, and new production applications.

Engineering Selection Recommendations

Chemi-Con U36D Series Substitutes (E36D401CAS472MEA5U, E36D401CDS472MEA5U, E36D401CSS472MEA5U, E36D401HLS472MEA5U, E36D401HPN472MEA5U)

These five Chemi-Con parts are direct electrical and mechanical equivalents to the obsolete E36D401CSS472MEA5M. All maintain identical capacitance, voltage rating, tolerance, ESR, lifetime specification, ripple current ratings, and physical dimensions. The primary distinction is product status: all five substitute parts are Active, ensuring long-term availability and supply chain continuity. All substitute parts meet ROHS3 compliance, providing enhanced environmental and regulatory alignment compared to the original part's standard RoHS designation.

Selection among these five Chemi-Con alternatives should be based on inventory availability and internal part numbering conventions. From a technical standpoint, all five parts are functionally interchangeable with the original E36D401CSS472MEA5M without design modification.

Nichicon LNC Series Substitutes (LNC2G472MSEH, LNC2G472MSEHBB, LNC2G472MSEHBN, LNC2G472MTEH)

The Nichicon LNC series parts offer enhanced performance characteristics while maintaining all primary equivalence criteria. These parts feature a 5000-hour lifetime at 85°C (compared to 2000 hours for the original part), representing a 2.5× improvement in rated operational life. Ripple current ratings are significantly higher: 18.3 A at 120 Hz and 25.62 A at 10 kHz, compared to 11.06 A and 15.484 A respectively for the original part. Physical height is reduced to 3.661 inches, providing a more compact form factor while maintaining the required 3.000-inch diameter and compatible lead spacing of 1.252 inches.

All four LNC variants are Active products with ROHS3 compliance. Selection among LNC2G472MSEH, LNC2G472MSEHBB, LNC2G472MSEHBN, and LNC2G472MTEH should be based on packaging and terminal configuration requirements specific to the application.

Nichicon LNY Series Substitute (LNY2G472MSEH)

The Nichicon LNY2G472MSEH provides an intermediate performance option between the original Chemi-Con specification and the enhanced LNC series. This part maintains the 2000-hour lifetime at 85°C matching the original part, while offering improved ripple current ratings of 16.2 A at 120 Hz and 22.68 A at 10 kHz. Physical height is 3.740 inches, slightly taller than the LNC series but shorter than the original part. Lead spacing of 1.252 inches and diameter of 3.000 inches remain compatible with the original design envelope.

The LNY2G472MSEH is an Active product with ROHS3 compliance, suitable for applications where the enhanced ripple current capability of the LNC series is not required but improved performance over the original part is desired.

Frequently Asked Questions (FAQ)

Q: Can I directly replace E36D401CSS472MEA5M with any of the Chemi-Con U36D series substitutes without circuit modification?

A: Yes. The five Chemi-Con U36D series parts (E36D401CAS472MEA5U, E36D401CDS472MEA5U, E36D401CSS472MEA5U, E36D401HLS472MEA5U, E36D401HPN472MEA5U) are complete electrical and mechanical equivalents. All parameters including capacitance, voltage rating, tolerance, ESR, lifetime, ripple current, and physical dimensions are identical. No circuit design changes are required.

Q: What are the key differences between Chemi-Con and Nichicon substitute options?

A: Chemi-Con U36D series parts maintain exact specification parity with the original part. Nichicon LNC series parts offer extended lifetime (5000 hours vs. 2000 hours at 85°C) and higher ripple current ratings, with a more compact physical height. Nichicon LNY series provides a middle-ground option with improved ripple current but matching lifetime. All substitutes meet the same voltage, capacitance, tolerance, and mounting requirements.

Q: Are there any physical installation differences between the original part and Nichicon substitutes?

A: Lead spacing differs slightly: the original part specifies 1.250 inches, while Nichicon parts specify 1.252 inches. This 0.002-inch difference is within standard mechanical tolerance for screw terminal spacing and does not require PCB or mounting hardware modification. Physical height varies: the original part is 4.125 inches tall, Nichicon LNC series is 3.661 inches, and Nichicon LNY series is 3.740 inches. All parts maintain the required 3.000-inch diameter. Verify that the reduced height of Nichicon options does not conflict with enclosure or thermal management design constraints.

Q: Which substitute part should I select for maximum performance?

A: Selection depends on application requirements. For direct replacement with no performance enhancement, any Chemi-Con U36D series part is appropriate. For extended operational life and higher ripple current capability, Nichicon LNC series parts (LNC2G472MSEH, LNC2G472MSEHBB, LNC2G472MSEHBN, LNC2G472MTEH) are recommended. For improved ripple current with matching lifetime specification, Nichicon LNY2G472MSEH is suitable.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed meet ROHS3 compliance. The original E36D401CSS472MEA5M meets standard RoHS compliance. All five Chemi-Con U36D series substitutes and all five Nichicon substitutes are ROHS3 compliant, providing enhanced environmental and regulatory alignment.

Q: What is the inventory status of these substitute parts?

A: All substitute parts are classified as Active products with current inventory availability. Chemi-Con U36D series parts range from 716 to 950 pieces in stock. Nichicon LNC series parts range from 684 to 1073 pieces in stock. Nichicon LNY2G472MSEH has 692 pieces in stock. Verify current availability with your component supplier before finalizing procurement decisions.

Q: Can I use Nichicon parts in applications originally designed for Chemi-Con?

A: Yes. All Nichicon substitutes meet or exceed the electrical specifications of the original Chemi-Con part. The primary consideration is physical height: Nichicon parts are shorter than the original, which is generally advantageous for space-constrained designs. Verify that the reduced height does not create thermal management or mechanical clearance issues in your specific application.

Q: What is the significance of the different Nichicon LNC part number suffixes (MSEH, MSEHBB, MSEHBN, MTEH)?

A: These suffixes indicate variations in terminal configuration, packaging format, or internal construction. All four variants maintain identical electrical specifications (4700 µF, 400 V, ±20%, 5000 hours at 85°C). Selection should be based on your specific terminal and packaging requirements. Consult detailed datasheets for terminal configuration specifics.
