Substitute Part Grouping Explanation
The MDF7C-12P-2.54DSA(96) qualifies as a direct substitute based on the following critical parameters:
- Same manufacturer (Hirose Electric Co., Ltd.)
- Identical series designation (MDF7)
- Matching position count (12 positions)
- Identical pitch specification (0.100" / 2.54mm)
- Single row configuration
- Through-hole mounting type
- Solder termination
- Gold contact finish on mating surfaces
- Matching overall contact length (0.984" / 25.00mm)
- Identical post length (0.118" / 3.00mm)
- RoHS compliant
- MSL rating of 1 (Unlimited)
The primary distinction is product status: MDF7C-12P-2.54DSA(01) is obsolete, while MDF7C-12P-2.54DSA(96) maintains active status with current manufacturing availability.

Frequently Asked Questions (FAQ)
Q: Are these connectors electrically interchangeable?
A: Yes. Both parts share identical electrical specifications including 3A current rating, 250VAC voltage rating, and gold contact finish on mating surfaces.
Q: Will the substitute part fit existing PCB designs?
A: Yes. The MDF7C-12P-2.54DSA(96) maintains identical mechanical dimensions, pitch spacing (0.100" / 2.54mm), overall contact length (0.984" / 25.00mm), and through-hole mounting configuration as the original part.
Q: What is the difference between the two part numbers?
A: The primary difference is product status. MDF7C-12P-2.54DSA(01) is obsolete, while MDF7C-12P-2.54DSA(96) is actively manufactured. The suffix designation (01 vs. 96) indicates different manufacturing batches or packaging configurations, but electrical and mechanical specifications remain identical.
Q: Are both parts RoHS compliant?
A: Yes. Both MDF7C-12P-2.54DSA(01) and MDF7C-12P-2.54DSA(96) are RoHS compliant with MSL rating of 1 (Unlimited).
Q: Can I use the substitute part in existing assemblies?
A: Yes. The substitute part is a direct replacement with no design or assembly process modifications required.
