Engineering Selection Recommendations

The MDF7-15P-2.54DSA(96) is a direct functional substitute for the obsolete MDF7-15P-2.54DSA(01). Both components share identical electrical specifications, mechanical dimensions, and material certifications. The substitute part maintains RoHS compliance and UL94 V-0 flammability rating, ensuring regulatory alignment with the original design.

The primary distinction between these parts is product status: MDF7-15P-2.54DSA(96) is currently active in production, providing supply chain continuity and long-term availability. The voltage rating specification differs slightly in notation (250V versus 250VAC), but both designations represent equivalent electrical performance for this connector class.

The style designation difference (Board to Board versus Board to Cable/Wire) reflects application context rather than fundamental incompatibility. Both connectors maintain identical contact geometry, pitch spacing, and termination characteristics required for PCB-level integration.

Frequently Asked Questions (FAQ)

Q: Can MDF7-15P-2.54DSA(96) be used as a direct replacement for MDF7-15P-2.54DSA(01)?

A: Yes. Both connectors share identical electrical ratings (3A, 250V), mechanical dimensions, contact configuration (15 positions, 0.100" pitch), and material specifications. The substitute part is fully compatible for through-hole solder termination applications.

Q: What is the significance of the style difference (Board to Board versus Board to Cable/Wire)?

A: Style designation indicates the intended mating application context. However, both connectors maintain identical contact geometry and electrical characteristics. The physical compatibility for PCB mounting and signal transmission remains unchanged.

Q: Does the packaging difference affect component functionality?

A: No. Packaging designation (Bag for MDF7-15P-2.54DSA(96)) affects only handling and storage logistics, not electrical or mechanical performance. The connector itself is identical regardless of packaging format.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain RoHS compliance, UL94 V-0 flammability rating, and identical moisture sensitivity level (MSL 1). Regulatory and safety certifications are equivalent.

Q: Why is the original part listed as obsolete?

A: Obsolescence status indicates the part is no longer in active production. MDF7-15P-2.54DSA(96) provides continuity by offering the same connector specifications in an actively manufactured variant.
