Frequently Asked Questions (FAQ)

Q: Can MDF7-7P-2.54DSA(96) be used as a direct replacement for MDF7-7P-2.54DSA(01)?

A: Yes. Both parts share identical electrical ratings (3A, 250V), mechanical dimensions, contact configuration (7-position, 2.54mm pitch), and material specifications. The substitute part is functionally equivalent for all applications requiring the original part.

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

A: The primary differences are product status and packaging. MDF7-7P-2.54DSA(01) is obsolete, while MDF7-7P-2.54DSA(96) is active. The substitute part is supplied in bag packaging. All electrical and mechanical specifications remain identical.

Q: Are there any compatibility concerns when switching to MDF7-7P-2.54DSA(96)?

A: No compatibility concerns exist. Both parts maintain the same connector type (header), contact type (male pin), pitch (2.54mm), and mounting method (through-hole solder). PCB footprints and mating connector requirements are identical.

Q: Does the voltage rating specification differ between the parts?

A: Both parts carry a 250V rating. The substitute part specifies 250VAC, while the original lists 250V. This represents a clarification of the voltage type rather than a specification change, as both parts are rated for the same voltage level.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.
