Key Parameters

Substitute Part Grouping Explanation

The 3M 952K (BULK) serves as a direct substitute based on the following alignment criteria:

Both components function as terminal connectors within the terminals category. The 952K is an active product with established supply availability, addressing the obsolescence status of the 30243. Substitution is valid where the application requires inline tap connector functionality with IDC termination for wire gauges 14-18 AWG. Both parts maintain ROHS3 compliance, ensuring regulatory consistency in applications subject to RoHS requirements. The 952K's fully insulated construction and flame retardant features provide equivalent electrical safety characteristics for connector splice applications.

Parameter Comparison

Engineering Selection Recommendations

The 3M 952K (BULK) is the specified substitute for the obsolete Littelfuse 30243. Selection of this substitute is supported by:

Active product status ensures ongoing availability and supply chain reliability. ROHS3 compliance alignment maintains regulatory conformance in applications subject to RoHS directives. The 952K's MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions, suitable for standard storage and handling conditions. Fully insulated construction and flame retardant properties provide equivalent safety performance for connector splice applications.

Frequently Asked Questions (FAQ)

Q: Why is the Littelfuse 30243 being replaced? A: The 30243 is classified as an obsolete product. The 3M 952K (BULK) is an active substitute that maintains functional equivalence while ensuring supply availability.

Q: Are the Littelfuse 30243 and 3M 952K mechanically compatible? A: Both components are terminal connectors within the terminals category. The 952K is specified as an inline tap connector with IDC termination for 14-18 AWG wire gauges. Mechanical compatibility depends on the specific connector interface requirements of the application.

Q: Do both parts meet the same regulatory requirements? A: Yes. Both the Littelfuse 30243 and 3M 952K are ROHS3 compliant, ensuring regulatory consistency in applications subject to RoHS directives.

Q: What is the packaging difference between these parts? A: The Littelfuse 30243 packaging is not specified. The 3M 952K is supplied in bulk packaging, suitable for high-volume applications and inventory management.

Q: What wire gauge range does the 3M 952K support? A: The 3M 952K is rated for 14-18 AWG wire gauges with IDC termination. Verify that the application wire gauge falls within this range before substitution.
