Substitute Part Grouping Explanation
Substitution eligibility for the DF3-7P-2DS is determined by strict equivalence across the following critical parameters:
- Connector type (Header)
- Number of positions (7)
- Pitch specification (0.079" / 2.00mm)
- Contact type (Male Pin)
- Mounting configuration (Through Hole, Right Angle)
- Shrouding design (Shrouded - 4 Wall)
- Current rating (3A)
- Operating temperature range (-55°C ~ 105°C)
- Fastening type (Push-Pull)
- Contact material and finish (Brass with Tin plating)
- Insulation material (Polyamide/Nylon)
The DF3A-7P-2DS meets all these criteria and qualifies as a direct substitute.

Engineering Selection Recommendations
The DF3A-7P-2DS is the direct substitute for the obsolete DF3-7P-2DS. Both parts share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: the DF3A-7P-2DS is active and ROHS3 compliant, whereas the original part is obsolete and RoHS non-compliant. For new designs or ongoing production requiring regulatory compliance, the DF3A-7P-2DS is the appropriate selection. Both parts maintain equivalent performance characteristics, contact ratings, and environmental operating ranges.
Frequently Asked Questions (FAQ)
Q: Can the DF3A-7P-2DS be used as a direct replacement for the DF3-7P-2DS?
A: Yes. The DF3A-7P-2DS is electrically and mechanically equivalent to the DF3-7P-2DS across all specified parameters, including pitch, position count, contact type, mounting configuration, and current rating.
Q: What is the primary difference between these two parts?
A: The DF3A-7P-2DS is an active product with ROHS3 compliance, while the DF3-7P-2DS is obsolete and RoHS non-compliant. Functionally, they are identical.
Q: Are there any compatibility concerns when substituting the DF3A-7P-2DS for the DF3-7P-2DS?
A: No compatibility concerns exist. Both parts feature identical mating pitch (2.00mm), contact geometry, shrouding design, and fastening mechanism. PCB layouts and mating connector specifications remain unchanged.
Q: What packaging is available for the substitute part?
A: The DF3A-7P-2DS is supplied in bulk packaging.
Q: Does the substitute part meet current regulatory requirements?
A: Yes. The DF3A-7P-2DS is ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.
