Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3E-2P-2V(20) is determined by strict equivalence across the following critical parameters:

• Connector Type & Series: Must be DF3 series header connector
• Position Count & Pitch: Exactly 2 positions at 0.079" (2.00mm) mating pitch
• Mounting Technology: Surface mount configuration required
• Electrical Ratings: 250VAC voltage rating and -55°C ~ 105°C operating temperature range
• Mechanical Design: Shrouded 4-wall design with push-pull fastening
• Contact Configuration: Male pin contacts with tin finish on brass material
• Termination Method: Solder termination with board guide and solder retention features

The DF3E-2P-2V(24) meets all substitution criteria as a direct equivalent within the DF3 series, with identical electrical and mechanical specifications. The primary distinction is product status and packaging configuration.
