Key Parameters

Substitute Part Grouping Explanation

Substitution of the LKS-50 is based on the following criteria derived from the provided parameters:

• Manufacturer Alignment: Both the main part and substitute are manufactured by Eaton - Bussmann Electrical Division, ensuring consistency in design standards and quality protocols.
• Regulatory Compliance: Both parts maintain RoHS compliance and share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications, confirming equivalence for export and procurement purposes.
• Moisture Sensitivity: The substitute part carries an MSL rating of Not Applicable, which does not conflict with the main part's MSL 1 rating and presents no compatibility concerns.
• Product Status Transition: The substitute part (LPS-RK-50SP) holds Active product status, providing long-term availability and supply chain continuity for applications currently using the obsolete LKS-50.

Parameter Comparison

Engineering Selection Recommendations

Selection between the LKS-50 and LPS-RK-50SP should be based on the following factors:

• Obsolescence Management: The LKS-50 is classified as obsolete. For new designs or long-term system support, the LPS-RK-50SP is the appropriate selection due to its Active product status and assured continued availability.
• Regulatory Compliance: Both parts satisfy RoHS requirements and carry identical export classifications (EAR99, HTSUS 8536.10.0040), making either part suitable for regulated procurement environments.
• Supply Chain Continuity: The LPS-RK-50SP maintains higher current inventory levels (886 Pcs) compared to the LKS-50 (743 Pcs), supporting consistent procurement timelines.
• Moisture Handling: Both parts present equivalent moisture management profiles. The LKS-50's MSL 1 rating and the LPS-RK-50SP's Not Applicable MSL rating do not present storage or handling conflicts.

Frequently Asked Questions (FAQ)

Q: Can the LPS-RK-50SP directly replace the LKS-50 in existing applications?

A: Both parts are manufactured by Eaton - Bussmann Electrical Division and share identical regulatory classifications (RoHS, ECCN, HTSUS). Substitution is supported based on the provided parameters. Application-specific electrical and mechanical requirements must be verified against the detailed specifications of each fuse type.

Q: Why is the LKS-50 listed as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this part number. The LPS-RK-50SP represents the active alternative within the Eaton - Bussmann product line.

Q: What is the significance of the different packaging specifications?

A: The LKS-50 is listed with packaging designation "-" (unspecified), while the LPS-RK-50SP is supplied in Bulk packaging. Packaging selection should align with procurement volume requirements and internal inventory management protocols.

Q: Are there any moisture sensitivity concerns with either part?

A: The LKS-50 carries an MSL rating of 1 (Unlimited), indicating minimal moisture sensitivity. The LPS-RK-50SP carries an MSL rating of Not Applicable. Neither part presents moisture-related handling or storage constraints.

Q: How do the inventory levels affect component selection?

A: Current inventory for the LKS-50 is 743 Pcs, while the LPS-RK-50SP maintains 886 Pcs. For procurement planning, the LPS-RK-50SP offers marginally higher immediate availability. Long-term sourcing should prioritize the active part (LPS-RK-50SP) to ensure sustained supply chain access.
