Substitute Part Grouping Explanation

The MDF7-11P-2.54DS(95) qualifies as a direct substitute based on the following critical parameters:

  • Identical manufacturer (Hirose Electric Co Ltd) and base series (MDF7)
  • Matching connector specifications: 11-position header, 0.100" (2.54mm) pitch, male pin contact type
  • Identical electrical ratings: 3A current, 250V voltage, -35°C ~ 85°C operating temperature
  • Matching mechanical specifications: through-hole, right-angle mounting, solder termination, push-pull fastening
  • Identical material composition: brass contacts with tin finish, PBT insulation
  • Equivalent compliance: RoHS compliant, UL94 V-0 flammability rating, MSL 1

The primary difference is application style: MDF7-11P-2.54DS(55) is configured for board-to-board connections, while MDF7-11P-2.54DS(95) is configured for board-to-cable/wire connections. Both maintain identical electrical and mechanical interface parameters at the mating surface.

Engineering Selection Recommendations

The MDF7-11P-2.54DS(95) is the appropriate substitute for the obsolete MDF7-11P-2.54DS(55). Both parts maintain identical electrical performance (3A at 250V), mechanical interface specifications (11-position, 0.100" pitch, right-angle through-hole), and compliance certifications (RoHS compliant, UL94 V-0). The MDF7-11P-2.54DS(95) carries active product status, ensuring long-term availability and supply chain continuity. The minor variation in contact length at the mating surface (0.293" versus 0.292") falls within standard manufacturing tolerances and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can MDF7-11P-2.54DS(95) directly replace MDF7-11P-2.54DS(55) in existing designs?

A: Yes. Both parts share identical electrical ratings (3A, 250V), mechanical pitch (0.100"), position count (11), and mounting configuration (through-hole, right-angle). The contact length variation of 0.001" is within standard tolerance ranges and does not impact mating compatibility.

Q: What is the primary difference between these two parts?

A: The MDF7-11P-2.54DS(55) is configured for board-to-board applications, while the MDF7-11P-2.54DS(95) is configured for board-to-cable/wire applications. Both maintain identical mating interface specifications.

Q: Are there compliance or certification differences?

A: No. Both parts are RoHS compliant, carry UL94 V-0 flammability rating, and maintain MSL 1 moisture sensitivity level. Electrical and thermal specifications are equivalent.

Q: Why is MDF7-11P-2.54DS(55) listed as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The MDF7-11P-2.54DS(95) provides functional equivalence with active product status, ensuring continued availability and support.

Q: Are packaging differences significant for component selection?

A: The MDF7-11P-2.54DS(55) is unspecified for packaging, while MDF7-11P-2.54DS(95) is supplied in bag packaging. This affects logistics and storage but does not impact electrical or mechanical performance.
