Key Parameters

Substitute Part Grouping Explanation

The DF3EA-3P-2V(21) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Identical series designation (DF3)
• Matching connector type (Header) and contact type (Male Pin)
• Same number of positions (3) and mating pitch (0.079" / 2.00mm)
• Identical mounting type (Surface Mount) and shrouding configuration (Shrouded - 4 Wall)
• Matching termination method (Solder) and fastening type (Push-Pull)
• Equivalent insulation height (0.232" / 5.90mm)
• Same insulation material (Polyamide/Nylon) and color (Beige)
• Identical flammability rating (UL94 V-0)
• Same moisture sensitivity level (MSL 1)

The substitute part maintains all critical mechanical and electrical interface parameters required for direct replacement in board-to-board or cable applications.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-3P-2V(21) is the appropriate substitute for the discontinued DF3DZ-3P-2V(75). Both parts share identical mechanical and electrical interface specifications, ensuring direct compatibility in existing designs.

The substitute part offers enhanced specifications in several areas: extended operating temperature range (-55°C to 105°C versus -30°C to 85°C), explicit voltage rating of 250VAC, and upgraded RoHS3 compliance status. The substitute is currently in active production with established supply availability in Tape & Reel packaging format.

Selection of the DF3EA-3P-2V(21) eliminates obsolescence risk while maintaining full functional equivalence for board-to-board and cable connector applications requiring 3-position, 2.00mm pitch shrouded headers with solder termination.

Frequently Asked Questions (FAQ)

Q: Are the DF3DZ-3P-2V(75) and DF3EA-3P-2V(21) mechanically interchangeable?
