Frequently Asked Questions (FAQ)

Q: Are MDF7-14S-2.54DSA and MDF7-14S-2.54DSA(55) mechanically interchangeable?

A: Yes. Both parts share identical connector type, position count, pitch, mounting method, and contact configuration. PCB layouts and mating interfaces are identical.

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

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and packaging format (unspecified vs. tray). All electrical and mechanical specifications are equivalent.

Q: Can I use MDF7-14S-2.54DSA(55) in existing designs specified for MDF7-14S-2.54DSA?

A: Yes. The substitute part maintains all critical parameters required for functional equivalence. No design changes are necessary.

Q: What does the "(55)" designation indicate?

A: The "(55)" suffix indicates the packaging variant (tray packaging) and product revision status within the MDF7 series.

Q: Are there any contact finish differences that affect performance?

A: Both parts feature tin-plated contacts on the mating surface. The substitute part specifies tin plating on the post surface as well, providing enhanced corrosion resistance and solderability.

Q: What is the current inventory status?

A: MDF7-14S-2.54DSA (obsolete): 937 pcs. MDF7-14S-2.54DSA(55) (active): 2133 pcs.
