Substitute Part Grouping Explanation
Substitution eligibility for the DF3-12P-2DS is determined by the following critical parameters:
- Connector type (Header)
- Contact type (Male Pin)
- Number of positions (12)
- Mating pitch (0.079" / 2.00mm)
- Mounting configuration (Through Hole, Right Angle)
- Shrouding style (Shrouded - 4 Wall)
- Current rating (3A)
- Operating temperature range (-55°C ~ 105°C)
- Termination method (Press-Fit, Solder)
- Fastening type (Push-Pull)
The DF3A-12P-2DS meets all these criteria and qualifies as a direct substitute.

Engineering Selection Recommendations
The DF3A-12P-2DS is a direct functional equivalent to the DF3-12P-2DS. Both parts share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: the DF3A-12P-2DS is currently active in production and carries ROHS3 compliance, whereas the original DF3-12P-2DS is obsolete and RoHS non-compliant. For new designs or ongoing production requiring regulatory compliance, the DF3A-12P-2DS is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part provides equivalent performance.
Frequently Asked Questions (FAQ)
Q: Are the DF3-12P-2DS and DF3A-12P-2DS mechanically interchangeable?
A: Yes. Both connectors share identical mounting type (through hole, right angle), shrouding configuration (4 wall), and physical dimensions including insulation height and contact geometry.
Q: What is the difference between these two part numbers?
A: The DF3A-12P-2DS is the active production variant with ROHS3 compliance. The DF3-12P-2DS is the obsolete predecessor. All electrical and mechanical specifications are identical.
Q: Can I use the DF3A-12P-2DS in place of the DF3-12P-2DS in existing designs?
A: Yes. The DF3A-12P-2DS provides full functional equivalence and is suitable for direct substitution in any application currently using the DF3-12P-2DS.
Q: What is the mating pitch for these connectors?
A: The mating pitch is 0.079 inches (2.00mm), which determines compatibility with corresponding receptacle connectors in the DF3 series.
Q: Are there packaging differences between these parts?
A: The DF3-12P-2DS is listed with no specified packaging, while the DF3A-12P-2DS is supplied in bulk packaging. Verify packaging requirements with your procurement specification.
Q: What is the current rating for this connector?
A: Both parts are rated for 3A continuous current per contact.
Q: What temperature range do these connectors support?
A: Both connectors operate across -55°C to 105°C, suitable for industrial and commercial temperature environments.
