Engineering Selection Recommendations

Both DF11-32DP-2DSA(24) and DF11-32DP-2DSA(01) are functionally equivalent to the obsolete DF11-32DP-2DSA(20) for all electrical and mechanical applications. Selection between substitute parts should be based on the following criteria:

DF11-32DP-2DSA(24) is suitable for applications requiring ROHS3 compliance with tin contact finish and tube packaging. This variant maintains the same electrical performance and mechanical compatibility as the original part.

DF11-32DP-2DSA(01) is suitable for applications requiring ROHS3 compliance with gold contact finish and bulk packaging. The gold contact finish provides enhanced corrosion resistance compared to tin finish.

The original DF11-32DP-2DSA(20) is RoHS non-compliant and obsolete. For new designs or ongoing production requiring regulatory compliance, either substitute part is appropriate based on contact finish and packaging requirements.

Frequently Asked Questions (FAQ)

Q: Are DF11-32DP-2DSA(24) and DF11-32DP-2DSA(01) fully compatible with DF11-32DP-2DSA(20)?

A: Yes. Both substitute parts maintain identical electrical ratings (2A, 250V), mechanical dimensions, pitch (2.00mm), number of positions (32), row configuration (2 rows), mounting type (through-hole), and termination method (solder). All three parts are from the same DF11 series and are mechanically and electrically interchangeable.

Q: What is the difference between the contact finishes?

A: DF11-32DP-2DSA(20) and DF11-32DP-2DSA(24) use tin contact finish. DF11-32DP-2DSA(01) uses gold contact finish. Gold finish provides superior corrosion resistance and is preferred for high-reliability applications or environments with moisture exposure.

Q: Why is the original part marked as obsolete?

A: The DF11-32DP-2DSA(20) is obsolete due to its RoHS non-compliant status. Both substitute parts are active products with ROHS3 compliance, making them the current production alternatives.

Q: Does packaging format affect electrical or mechanical performance?

A: No. Packaging format (tube for DF11-32DP-2DSA(24) and bulk for DF11-32DP-2DSA(01)) affects only handling, storage, and ordering logistics. Electrical and mechanical performance are identical regardless of packaging.

Q: Can I use DF11-32DP-2DSA(01) in place of DF11-32DP-2DSA(24)?

A: Yes. Both parts are functionally equivalent. The choice between them depends on packaging preference and whether gold contact finish is required for your application.
