Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3A-3P-2DSA(18) is determined by the following critical parameters:

• Connector type (Header)
• Number of positions (3)
• Pitch specification (0.079" / 2.00mm)
• Mounting method (Through Hole)
• Current rating (3A minimum)
• Operating temperature range (-55°C ~ 105°C)
• Shrouding configuration (Shrouded - 4 Wall)
• Contact material and finish (Brass with Tin plating)

The DF3A-3P-2DSA qualifies as a direct substitute based on identical electrical and mechanical specifications across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The DF3A-3P-2DSA serves as the direct functional equivalent to the obsolete DF3A-3P-2DSA(18). Both parts share identical electrical and mechanical specifications, including connector type, position count, pitch, mounting method, current rating, and operating temperature range.

The substitute part offers the advantage of active product status, ensuring ongoing availability and manufacturing support. The DF3A-3P-2DSA maintains full compliance with RoHS3 and REACH requirements, with MSL rating of 1 (Unlimited) matching the original specification. All contact materials, finishes, and insulation properties remain consistent between the two parts.

For applications currently using DF3A-3P-2DSA(18), direct substitution with DF3A-3P-2DSA is electrically and mechanically compatible without design modification.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between DF3A-3P-2DSA(18) and DF3A-3P-2DSA?
