Substitute Part Grouping Explanation
Substitution eligibility for the DF3-10P-2DS is determined by strict alignment of the following critical parameters:
- Connector type (Header)
- Contact type (Male Pin)
- Mating pitch (0.079" / 2.00mm)
- Number of positions (10)
- Number of rows (1)
- Mounting configuration (Through Hole, Right Angle)
- Shrouding design (Shrouded - 4 Wall)
- Current rating (3A minimum)
- Operating temperature range (-55°C ~ 105°C minimum)
- Insulation material (Polyamide/Nylon)
- Flammability rating (UL94 V-0)
The DF3A-10P-2DS meets all substitution criteria as a direct equivalent from the same manufacturer series, with identical electrical and mechanical specifications. The primary distinction is product status: DF3A-10P-2DS is active production, whereas DF3-10P-2DS is obsolete.

Engineering Selection Recommendations
The DF3A-10P-2DS is the direct substitute for the obsolete DF3-10P-2DS. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in existing designs. The DF3A-10P-2DS offers the advantage of active production status and ROHS3 compliance, whereas the original part is RoHS non-compliant. Selection between these parts depends on regulatory requirements: applications subject to RoHS3 mandates must use DF3A-10P-2DS, while legacy systems may continue with either variant based on inventory availability and compliance scope.
Frequently Asked Questions (FAQ)
Q: Can DF3A-10P-2DS directly replace DF3-10P-2DS in existing assemblies?
A: Yes. Both parts are electrically and mechanically identical. The DF3A-10P-2DS maintains the same 10-position, 2.00mm pitch, 3A current rating, through-hole right-angle mounting, and shrouded 4-wall construction. No design modifications are required.
Q: What is the primary difference between these two parts?
A: Product status and RoHS compliance. DF3-10P-2DS is obsolete and RoHS non-compliant. DF3A-10P-2DS is in active production and ROHS3 compliant. Both maintain identical functional specifications.
Q: Are there packaging differences between DF3-10P-2DS and DF3A-10P-2DS?
A: The main part is listed without specified packaging, while DF3A-10P-2DS is supplied in bulk packaging. Confirm packaging requirements with your procurement process.
Q: Does the RoHS3 compliance of DF3A-10P-2DS affect electrical performance?
A: No. RoHS3 compliance relates to material composition and environmental regulations, not electrical or mechanical performance. Both parts operate identically within the specified -55°C ~ 105°C temperature range and 3A current rating.
Q: What is the moisture sensitivity level for these connectors?
A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
