The substitute part carries Active product status, ensuring ongoing availability and manufacturing support from Hirose Electric Co Ltd.

Both parts maintain RoHS compliance and identical moisture sensitivity ratings. The voltage rating specification differs only in notation (250V versus 250VAC), representing the same electrical specification. Packaging configuration differs (Bag versus standard), which does not affect electrical or mechanical performance.

Selection of the MDF7-25P-2.54DSA(96) is appropriate for applications requiring the MDF7-25P-2.54DSA(01), with the advantage of active product status and current manufacturing availability.

Frequently Asked Questions (FAQ)

Q: Can MDF7-25P-2.54DSA(96) be used as a direct replacement for MDF7-25P-2.54DSA(01)?

A: Yes. Both parts share identical electrical ratings (3A, 250V), mechanical dimensions (25 positions, 2.54mm pitch), contact specifications (gold-plated brass, square male pins), and material properties (PBT insulation, UL94 V-0). The substitute part is Active status, ensuring procurement availability.

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

A: The primary differences are product status and packaging. MDF7-25P-2.54DSA(01) is Obsolete with standard packaging, while MDF7-25P-2.54DSA(96) is Active with Bag packaging. All functional and electrical specifications are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts maintain identical contact lengths (mating: 0.394", post: 0.118", overall: 0.612"), insulation height (0.100"), and pitch spacing (0.100"). Through-hole mounting footprints are identical.

Q: Does packaging affect connector performance?

A: No. Packaging configuration (Bag versus standard) does not affect electrical performance, mechanical compatibility, or functional characteristics. Both packaging types provide equivalent protection during storage and transport.
