Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3A-7P-2DSA(16) is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (7)
• Number of rows (1)
• Pitch - mating (0.079" / 2.00mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Press-Fit, Solder)
• Current rating (3A)
• Operating temperature range (-55°C ~ 105°C)
• Contact material (Brass)
• Insulation material (Polyamide/Nylon)
• Flammability rating (UL94 V-0)
• Mated stacking height (5mm)

The substitute part DF3A-7P-2DSA meets all these criteria and belongs to the same DF3 series, ensuring mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DF3A-7P-2DSA serves as the direct substitute for the obsolete DF3A-7P-2DSA(16). Both parts are manufactured by Hirose Electric Co Ltd and maintain identical electrical and mechanical specifications across all critical parameters.

The substitute part DF3A-7P-2DSA carries active product status, ensuring ongoing availability and supply chain support. The part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both parts maintain UL94 V-0 flammability certification and unlimited moisture sensitivity level (MSL 1), suitable for standard storage and handling conditions.

Selection of the active DF3A-7P-2DSA eliminates obsolescence risk while maintaining full compatibility with existing designs and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Are DF3A-7P-2DSA(16) and DF3A-7P-2DSA mechanically interchangeable?
