Key Parameters

Substitute Part Grouping Explanation

Substitute parts are qualified based on identical electrical and mechanical parameters: 50A current rating, 415V AC / 80V DC voltage ratings, two-pole configuration, lever actuation, panel mount design, and magnetic hydraulic delay protection. All substitutes maintain RoHS compliance and MSL 1 rating. Substitution is valid across LEL and IEL series families when these core parameters align. Packaging variations (Bulk or standard) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and full RoHS compliance with MSL 1 rating, matching the original LELHK11-0-SW-50.0-AV-01 specification. Selection among qualified substitutes may be based on packaging preference (Bulk or standard) and current inventory availability. The LEL and IEL series families are interchangeable within this parameter set. ECCN EAR99 and HTSUS 8536.20.0020 classifications apply uniformly across all qualified substitutes.

Frequently Asked Questions (FAQ)

Q: Can LEL series parts substitute for IEL series parts in this application? A: Yes. Both series maintain identical electrical ratings (50A, 415V AC, 80V DC), mechanical configuration (two-pole, lever-actuated, panel mount), and protection type (magnetic hydraulic delay). Series designation does not affect substitution eligibility when core parameters match.

Q: Does packaging type affect compatibility? A: No. Bulk and standard packaging are logistics variants only. Electrical and mechanical specifications remain identical regardless of packaging designation.

Q: What parameters must remain constant for substitution? A: Current rating (50A), AC voltage (415V), DC voltage (80V), pole count (2), mounting type (panel mount), actuator type (lever), and protection mechanism (magnetic hydraulic delay) must all match the original part specification.

Q: Are all substitutes RoHS compliant? A: Yes. All listed substitute parts are RoHS compliant with MSL 1 (Unlimited) rating, matching the original part's environmental and regulatory status.

Q: Can I use a substitute part with different current or voltage ratings? A: No. Substitution is valid only when current and voltage ratings are identical to the original specification. Parts with different electrical ratings are not qualified substitutes for this application.
