• Pitch - Mating: 0.079" (2.00mm) maintained
• Connector Type: Header configuration maintained
• Contact Type: Male Pin maintained
• Mounting Type: Through Hole, Right Angle maintained
• Shrouding: Shrouded - 4 Wall maintained
• Base Product Number: DF3A series maintained

The substitute part DF3A-7P-2DS differs from the obsolete DF3A-7P-2DS(10) only in packaging designation and product status. The electrical and mechanical specifications remain identical, ensuring direct functional replacement in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The DF3A-7P-2DS serves as the direct active substitute for the obsolete DF3A-7P-2DS(10). Selection of this substitute is supported by:

• Product Status Alignment: The substitute maintains the DF3A base product number and series designation, confirming manufacturer continuity within the same connector family.
• Compliance Certifications: The active substitute is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for new manufacturing and repair operations.
• Electrical and Mechanical Compatibility: All critical parameters—position count, pitch, contact type, mounting configuration, and shrouding—are identical between the obsolete and active parts, ensuring direct PCB-level compatibility without design modification.
• Availability: The substitute part is currently in active production with confirmed inventory, eliminating supply chain risk associated with obsolete component sourcing.

Frequently Asked Questions (FAQ)

Q: Can DF3A-7P-2DS be used as a direct replacement for DF3A-7P-2DS(10)?

A: Yes. Both parts share identical electrical and mechanical specifications: 7 positions, 2.00mm pitch, male pin contacts, through-hole right-angle mounting, and 4-wall shrouding. The difference is product status and packaging designation only.

Q: What does the "(10)" designation in DF3A-7P-2DS(10) indicate?

A: The "(10)" suffix typically indicates a specific packaging or tape-reel configuration from the original production run. The base part number DF3A-7P-2DS remains functionally identical regardless of this suffix.

Q: Are there any compliance differences between the obsolete and active parts?

A: The active substitute DF3A-7P-2DS carries ROHS3 Compliant and REACH Unaffected certifications. The obsolete part's compliance status is not specified in available documentation. For new designs or manufacturing, the active substitute meets current regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) difference?

A: The obsolete part lists MSL as Not Applicable. The active substitute is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can this connector be used in high-temperature applications?

A: The active substitute DF3A-7P-2DS is rated for -55°C to 105°C operating temperature. The obsolete part's temperature rating is not specified. Verify your application requirements against this range.

Q: What is the current-carrying capacity?

A: The active substitute DF3A-7P-2DS is rated for 3A per contact. The obsolete part's current rating is not specified. Confirm your circuit requirements do not exceed this limit.
