Frequently Asked Questions (FAQ)

Q: What makes DF11-2428SCFA(04) a direct substitute for DF11-2428SCFA(43)?

A: Both parts share identical specifications for wire gauge (24-28 AWG), contact type (socket), termination method (crimp), and series designation (DF11). The primary difference is the contact finish and product status, with the substitute offering gold plating and active availability.

Q: Are there any compatibility concerns when switching from DF11-2428SCFA(43) to DF11-2428SCFA(04)?

A: No compatibility concerns exist. The parts are mechanically and electrically interchangeable within the DF11 series framework. The gold contact finish of the substitute provides enhanced performance characteristics.

Q: What is the significance of the MSL rating difference?

A: The original part lists MSL as Not Applicable, while the substitute specifies MSL 1 (Unlimited). This indicates the substitute part has defined moisture sensitivity handling with unlimited floor life, providing clearer storage and handling requirements for manufacturing environments.

Q: Does the RoHS compliance status affect substitution decisions?

A: RoHS compliance on the substitute part ensures adherence to current environmental and regulatory standards. This is a beneficial characteristic for new designs and procurement cycles.

Q: What is the packaging difference between these parts?

A: The substitute part DF11-2428SCFA(04) is supplied in Cut Tape (CT) packaging, which is standard for component distribution and automated assembly processes.
