Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HR10A-7P-4SC is determined by strict equivalence across the following critical parameters:

• Connector type (Plug Housing for Female Sockets)
• Number of positions (4)
• Shell size - insert (7)
• Contact size (1.0mm)
• Mounting type (Free Hanging In-Line)
• Fastening type (Push-Pull)
• Orientation (Keyed)
• Shell material and finish (Zinc Alloy, Nickel)
• Operating temperature range (-20°C ~ 85°C)
• Material flammability rating (UL94 V-0)
• Contact type (Crimp)

The HR10A-7P-4SC(73) meets all these criteria and qualifies as a direct substitute. The primary distinction between the main part and its substitute is product status and regulatory compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The HR10A-7P-4SC(73) is the direct substitute for the obsolete HR10A-7P-4SC. Both parts are electrically and mechanically identical across all functional parameters.

The HR10A-7P-4SC(73) offers the advantage of active product status, ensuring ongoing manufacturer support and availability. Additionally, the HR10A-7P-4SC(73) achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the HR10A-7P-4SC(73) is the appropriate selection.

The HR10A-7P-4SC(73) is REACH Affected, compared to the original part's REACH Unaffected status. This distinction reflects updated regulatory classification and does not affect functional compatibility.
