Key Parameters

Substitute Part Grouping Explanation

Substitution of the MA35-40P-2DS(71) is determined by strict equivalence across the following critical parameters:

• Connector series and manufacturer (MA35, Hirose Electric)
• Electrical specifications: 40 positions, 2 rows, 2.00mm pitch, 2A current, 200VAC voltage
• Mechanical configuration: Through-hole, right-angle mounting, male pin contacts
• Contact material and finish: Brass with tin plating
• Insulation material: Polyamide (PA), Nylon
• Operating temperature range: -55°C to 85°C
• Flammability rating: UL94 V-0

The MA35-40P-2DS(51) qualifies as a direct substitute based on identical electrical and mechanical parameters. The primary distinction is product status and packaging configuration.
