Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF11-12DS-2V(20) is based on electrical and mechanical compatibility across the following critical parameters:

• 12-position receptacle configuration with 0.079" (2.00mm) pitch mating
• 2-row arrangement with 0.079" (2.00mm) row spacing
• Surface mount solder termination with friction lock fastening
• 2A current rating and 250V voltage rating
• Operating temperature range of -30°C to 85°C
• UL94 V-0 flammability rating
• Tin contact finish on mating surface

The DF11Z-12DS-2V(20) meets all these criteria and is identified as a direct substitute. Both parts share the same electrical performance envelope, mechanical interface dimensions, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The DF11Z-12DS-2V(20) is the direct substitute for the obsolete DF11-12DS-2V(20). Both connectors are electrically and mechanically identical across all critical parameters: 12-position receptacle configuration, 0.079" (2.00mm) pitch, 2A/250V ratings, and identical operating temperature range.

The DF11Z-12DS-2V(20) offers improved compliance status, meeting ROHS3 requirements compared to the non-compliant original part. The substitute maintains identical mechanical interface dimensions and electrical performance, ensuring drop-in compatibility in existing designs.

For new designs or redesigns, the DF11Z-12DS-2V(20) is the appropriate selection due to its active Last Time Buy status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can DF11Z-12DS-2V(20) be used as a direct replacement for DF11-12DS-2V(20)?

A: Yes. Both connectors share identical electrical ratings (2A, 250V), mechanical dimensions (12-position, 0.079" pitch, 2-row configuration), operating temperature range (-30°C to 85°C), and surface mount solder termination. The connectors are mechanically and electrically interchangeable.

Q: What is the difference between DF11-12DS-2V(20) and DF11Z-12DS-2V(20)?

A: The primary differences are product status and regulatory compliance. The DF11-12DS-2V(20) is obsolete and RoHS non-compliant, while the DF11Z-12DS-2V(20) is Last Time Buy and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The DF11Z-12DS-2V(20) is supplied in tube packaging, while packaging information for the DF11-12DS-2V(20) is not specified. This does not affect electrical or mechanical compatibility.

Q: What contact materials are used in each connector?

A: The DF11-12DS-2V(20) uses brass contacts, while the DF11Z-12DS-2V(20) uses phosphor bronze contacts. Both maintain tin finish on mating surfaces and are compatible with the same mating interfaces.

Q: Should new designs use DF11Z-12DS-2V(20) instead of DF11-12DS-2V(20)?

A: Yes. The DF11Z-12DS-2V(20) is the recommended selection for new designs due to its active Last Time Buy status and ROHS3 compliance. The original part is obsolete and should not be specified for new applications.
