Substitute Part Grouping Explanation

Substitution of the DF9-9S-1V(20) is based on strict equivalence of the following electrical and mechanical parameters:

• Number of positions: 9
• Pitch: 0.039" (1.00mm)
• Number of rows: 2
• Connector type: Receptacle, Outer Shroud Contacts
• Mounting type: Surface Mount
• Contact finish: Tin
• Mated stacking height: 4.3mm
• Height above board: 0.130" (3.30mm)
• Series: DF9

The substitute part DF9-9S-1V(32) maintains identical electrical and mechanical specifications while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The DF9-9S-1V(32) is the direct substitute for the DF9-9S-1V(20). Both parts share identical electrical and mechanical specifications within the DF9 series. The primary distinction is product status and regulatory compliance: the DF9-9S-1V(32) is active and ROHS3 compliant, whereas the DF9-9S-1V(20) is obsolete and RoHS non-compliant. For new designs and ongoing production, the DF9-9S-1V(32) is the appropriate selection. The substitute part is available in Tape & Reel packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Are the DF9-9S-1V(20) and DF9-9S-1V(32) mechanically interchangeable?

A: Yes. Both parts are 9-position receptacles with identical pitch (1.00mm), row configuration (2 rows), mounting type (surface mount), and physical dimensions (4.3mm mated stacking height, 0.130" height above board).

Q: What is the difference between these two part numbers?

A: The primary differences are product status and regulatory compliance. The DF9-9S-1V(32) is an active product with ROHS3 compliance and specified contact finish thickness (39.4µin / 1.00µm), while the DF9-9S-1V(20) is obsolete and RoHS non-compliant.

Q: Can I use DF9-9S-1V(32) in place of DF9-9S-1V(20) in existing designs?

A: Yes. The substitute part maintains all critical electrical and mechanical parameters required for functional equivalence. Verify PCB layout compatibility with the specified mounting type (surface mount) and connector orientation.

Q: What packaging is available for the substitute part?

A: The DF9-9S-1V(32) is supplied in Tape & Reel (TR) packaging, standard for automated surface mount assembly.

Q: Are there any compliance considerations when switching to the substitute part?

A: The DF9-9S-1V(32) is ROHS3 compliant and REACH unaffected, offering improved regulatory alignment compared to the obsolete DF9-9S-1V(20).
