Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5-520527-3 is determined by strict equivalence across the following critical parameters: connector type (SDL, Plug), position count (8 positions), cable type (ribbon), shielding configuration (shielded), termination method (crimp), wire gauge compatibility (26-28 AWG), current rating (1.5 A), voltage rating (30V), contact finish (gold), and housing material (polycarbonate). The substitute part 5-1761187-3 maintains identical specifications across all these parameters, ensuring functional and mechanical compatibility. The primary distinction between the main part and its substitute is product status: the original part is obsolete, while the substitute is active in production with current RoHS3 compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 5-1761187-3 is the direct functional equivalent of the 5-520527-3 across all electrical and mechanical parameters. Selection of the substitute part is supported by the following factors:

Product Status: The 5-1761187-3 maintains active production status, ensuring long-term component availability and supply chain continuity compared to the obsolete 5-520527-3.

Regulatory Compliance: The 5-1761187-3 carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. The original part is RoHS non-compliant, which may present compliance barriers in new designs or applications subject to RoHS directives.

Electrical and Mechanical Compatibility: Both parts are identical in connector type, position count, shielding, termination method, wire gauge, current rating, voltage rating, contact finish, and housing material. No design modifications are required for substitution.

Packaging: The 5-1761187-3 is supplied in bulk packaging, which may differ from the original part's packaging specification. Verify packaging requirements for your specific procurement and assembly processes.
