Key Parameters

Substitute Part Grouping Explanation

The DF3-9S-2DSA(55) qualifies as a direct substitute for the DF3-9S-2DSA(50) based on the following critical parameters:

• Connector Series & Type: Both parts belong to the DF3 series and function as 9-position receptacles
• Electrical Specifications: Identical pitch (0.079"/2.00mm), current rating (3A), and voltage rating (30VAC)
• Mechanical Interface: Matching through-hole mounting, solder termination, and friction lock fastening
• Contact Configuration: Both feature gold-plated mating contacts with identical insulation material (Polyamide/Nylon) and contact geometry
• Environmental Ratings: Identical operating temperature range (-30°C ~ 85°C) and flammability rating (UL94 V-0)

The primary distinction is product status: DF3-9S-2DSA(50) is obsolete, while DF3-9S-2DSA(55) is active with current manufacturing availability.
