Substitute Part Grouping Explanation

Substitution of the DF3A-7P-2DSA(10) is based on electrical and mechanical parameter equivalence within the DF3 series. The substitute part must maintain identical specifications across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (7)
• Mating pitch (0.079" / 2.00mm)
• Shrouding configuration (Shrouded - 4 Wall)
• Mounting method (Through Hole)
• Termination type (Press-Fit, Solder)
• Current rating (3A)
• Operating temperature range (-55°C ~ 105°C)
• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (1)

The direct substitute DF3A-7P-2DSA differs from the main part only in product status (Active vs. Obsolete), packaging configuration (Bulk vs. standard), and insulation color (Black vs. White). These differences do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DF3A-7P-2DSA serves as the direct functional equivalent to the obsolete DF3A-7P-2DSA(10). Both parts are manufactured by Hirose Electric within the DF3 series and maintain identical electrical and mechanical specifications. The substitute part is currently in active production status, ensuring supply chain continuity.

The DF3A-7P-2DSA maintains RoHS3 compliance, exceeding the RoHS compliance level of the original part. Both parts carry identical ECCN and HTSUS classifications. The insulation color difference (Black vs. White) and packaging configuration (Bulk vs. standard) do not affect functional performance or circuit compatibility.

For applications requiring the obsolete DF3A-7P-2DSA(10), the active DF3A-7P-2DSA is the appropriate direct replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Are the DF3A-7P-2DSA(10) and DF3A-7P-2DSA electrically identical?

A: Yes. Both parts maintain identical electrical specifications including 3A current rating, -55°C to 105°C operating temperature range, and UL94 V-0 flammability rating.

Q: Does the insulation color difference affect compatibility?

A: No. Insulation color is a visual identifier only and does not affect electrical or mechanical performance. The color difference does not impact circuit functionality or mating characteristics.

Q: What is the significance of the product status change from Obsolete to Active?

A: The Active status of DF3A-7P-2DSA indicates current manufacturing availability and supply chain support. This ensures reliable sourcing for new production and replacement applications.

Q: Are there mechanical compatibility concerns between these parts?

A: No. Both parts share identical mechanical specifications including 2.00mm pitch, 7-position configuration, through-hole mounting, shrouded 4-wall design, and 5mm mated stacking height.

Q: How does the RoHS3 compliance of the substitute affect compatibility?

A: RoHS3 compliance is a regulatory enhancement that does not affect component functionality. The substitute part meets or exceeds the compliance requirements of the original part.

Q: Is the packaging difference significant for circuit board assembly?

A: Packaging configuration (Bulk vs. standard) affects procurement and handling procedures but does not impact the component's electrical or mechanical performance in the circuit.
