Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2066046-2 is based on strict equivalence of the following critical parameters:

• Current Rating: 20 A (electrical compatibility)
• Fuse Size: 0.433" L x 0.152" W (11.00mm x 3.85mm) (mechanical fit)
• Fuse Type: Blade (connector interface standard)
• Number of Circuits: 2 (circuit configuration)
• Orientation: Vertical (mounting and installation)
• Termination Style: Quick Connect (electrical connection method)
• Fuseholder Type: Holder (functional classification)
• For Use With: Miniature (ATM) (application category)

The substitute part 2066046-4 meets all these criteria. While the 2066046-4 includes a specified voltage rating of 24V and carries active product status with ROHS3 compliance, these attributes represent enhancements to the original specification rather than deviations. The mechanical and electrical core parameters remain identical, permitting direct substitution in applications where the original 2066046-2 was specified.

Parameter Comparison

Engineering Selection Recommendations

The 2066046-4 serves as the direct substitute for the obsolete 2066046-2 based on identical core electrical and mechanical specifications. Selection of the 2066046-4 is supported by the following factors:

Product Status: The 2066046-4 maintains active product status, ensuring continued availability and manufacturing support. The 2066046-2 is classified as obsolete, limiting future procurement options.

Compliance: The 2066046-4 carries ROHS3 compliance certification, representing current regulatory alignment. Both parts are RoHS compliant and carry EAR99 ECCN classification.

Electrical Equivalence: Both parts are rated for 20 A operation with identical fuse dimensions (0.433" L x 0.152" W), ensuring electrical performance parity in 2-circuit blade fuse applications.

Mechanical Compatibility: Vertical orientation, quick connect termination, and miniature (ATM) fuse compatibility are identical between both parts, permitting direct installation without mechanical modification.

Voltage Rating: The 2066046-4 specifies 24V operation, whereas the 2066046-2 does not include a voltage specification. This represents a defined operational envelope for the substitute part and does not restrict its use in applications where the original part was employed.
