Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF9-11S-1V(20) is determined by strict equivalence across the following parameters:

• Series designation (DF9)
• Number of positions (11)
• Pitch specification (1.00mm)
• Number of rows (2)
• Connector type (Receptacle, Outer Shroud Contacts)
• Mounting type (Surface Mount)
• Contact finish material (Tin)
• Mated stacking height (4.3mm)
• Height above board (3.30mm)
• Features (Board Guide, Solder Retention)

The DF9-11S-1V(32) meets all these criteria and is identified as a direct substitute. The primary distinction between these parts is product status and packaging configuration, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The DF9-11S-1V(32) is the direct functional equivalent of the DF9-11S-1V(20). All electrical and mechanical parameters are identical. Selection between these parts should be based on the following criteria:

Product Status: The DF9-11S-1V(20) is obsolete. The DF9-11S-1V(32) is active and maintains current manufacturing support from Hirose Electric Co Ltd.

Regulatory Compliance: The DF9-11S-1V(32) is RoHS compliant, whereas the DF9-11S-1V(20) is RoHS non-compliant. Applications subject to RoHS requirements must use the DF9-11S-1V(32).

Packaging: The DF9-11S-1V(32) is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The DF9-11S-1V(20) is supplied in bulk packaging.

For new designs and production continuity, the DF9-11S-1V(32) is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are the DF9-11S-1V(20) and DF9-11S-1V(32) electrically interchangeable?

A: Yes. Both parts are 11-position receptacles with identical pitch (1.00mm), row configuration (2), contact finish (Tin), and mated stacking height (4.3mm). They are electrically and mechanically interchangeable.

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

A: The primary differences are product status, RoHS compliance, and packaging. The DF9-11S-1V(20) is obsolete and RoHS non-compliant, supplied in bulk. The DF9-11S-1V(32) is active, RoHS compliant, and supplied in Tape & Reel format.

Q: Can I use the DF9-11S-1V(32) as a direct replacement in existing assemblies?

A: Yes. The DF9-11S-1V(32) is a direct substitute with identical form, fit, and function. No design modifications are required.

Q: Why is the contact finish thickness specified for only one part?

A: Contact finish thickness is provided for the DF9-11S-1V(32) (39.4µin / 1.00µm) but not for the DF9-11S-1V(20). Both parts use Tin contact finish and are functionally equivalent for interconnection purposes.

Q: Which part should I specify for new production?

A: Specify the DF9-11S-1V(32). It is active, RoHS compliant, and maintains manufacturing availability.
