• Contact Configuration: Male pin, square contact shape
• Electrical Ratings: 3A current, 250V voltage minimum
• Mounting Method: Through hole solder termination
• Material Compliance: PBT insulation, brass contacts, UL94 V-0 flammability rating
• Environmental Range: -35°C to 85°C operating temperature

The substitute part MDF7B-11P-2.54DSA(96) maintains all critical parameters within the allowed specifications for this connector category.

Parameter Comparison

Engineering Selection Recommendations

The MDF7B-11P-2.54DSA(96) is the direct active equivalent for the obsolete MDF7B-11P-2.54DSA(01). Both parts maintain identical electrical and mechanical specifications across all critical parameters. The substitute part carries active product status from Hirose Electric Co Ltd, ensuring continued availability and manufacturing support.

Both parts satisfy RoHS compliance requirements and maintain UL94 V-0 flammability certification. The voltage rating specification differs only in notation (250V versus 250VAC), representing the same electrical performance envelope. Overall contact length shows a negligible difference of 0.01mm (22.01mm versus 22.00mm), which falls within standard manufacturing tolerances and does not affect functional compatibility.

Selection of the MDF7B-11P-2.54DSA(96) provides access to active inventory and ongoing manufacturer support while maintaining full electrical and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can MDF7B-11P-2.54DSA(96) be used as a direct replacement for MDF7B-11P-2.54DSA(01)?

A: Yes. Both parts are identical in electrical ratings (3A, 250V), mechanical configuration (11 positions, 2.54mm pitch), and material specifications (PBT insulation, brass contacts, UL94 V-0). The substitute part is the active equivalent.

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

A: The suffix designation (01 versus 96) indicates different manufacturing batches or packaging configurations. The MDF7B-11P-2.54DSA(96) is supplied in bag packaging and carries active product status, while the (01) variant is obsolete.

Q: Are there any compatibility concerns with PCB layout or mating connectors?

A: No. Both parts maintain identical pitch (2.54mm), position count (11), and contact geometry. Existing PCB layouts and mating connectors designed for the (01) variant are fully compatible with the (96) variant.

Q: What is the significance of the voltage rating notation difference (250V versus 250VAC)?

A: Both specifications represent the same voltage performance envelope. The notation difference does not affect electrical compatibility or application suitability.

Q: Is the 0.01mm difference in overall contact length significant?

A: No. This difference (22.01mm versus 22.00mm) falls within standard manufacturing tolerances for connector components and does not affect functional performance or mating characteristics.

Q: Why should the active part be selected over the obsolete part?

A: The MDF7B-11P-2.54DSA(96) carries active product status, ensuring continued availability, manufacturing support, and compliance with current industry standards. The (01) variant is obsolete and subject to supply discontinuation.
