Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF5A-2P-5DSA(78) is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Number of positions (2)
• Pitch spacing (5.00mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Contact type (Male Pin)
• Termination method (Solder)
• Operating temperature range (-35°C ~ 85°C)
• Material flammability rating (UL94 V-0)
• RoHS compliance status

The DF5A-2P-5DSA(35) meets all substitution criteria as a direct equivalent within the DF5 series.

Parameter Comparison

Engineering Selection Recommendations
