Substitute Part Grouping Explanation

The MDF7-12D-2.54DSA(95) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

  • Identical series designation (MDF7)
  • Identical connector type (Receptacle, Bottom Entry)
  • Identical number of positions (12)
  • Identical pitch spacing (0.100" / 2.54mm)
  • Identical row configuration (2 rows with 0.100" spacing)
  • Identical mounting type (Through Hole)
  • Identical termination method (Solder)
  • Identical fastening type (Push-Pull)
  • Identical electrical ratings (3A current, 250VAC voltage)
  • Identical operating temperature range (-35°C ~ 85°C)
  • Identical insulation material and color (Polyamide/Nylon, Black)
  • Identical contact material and finish (Phosphor Bronze, Tin)

The primary distinction is product status: MDF7-12D-2.54DSA(95) is active, whereas MDF7-12D-2.54DSA(55) is obsolete.

Engineering Selection Recommendations

The MDF7-12D-2.54DSA(95) is the direct substitute for the obsolete MDF7-12D-2.54DSA(55). Both parts share identical electrical, mechanical, and thermal specifications within the MDF7 series. The substitute maintains full compatibility across all functional parameters.

The MDF7-12D-2.54DSA(95) carries active product status and ROHS3 compliance, providing supply continuity and regulatory alignment for current production requirements. The original part's RoHS compliance status is superseded by the substitute's ROHS3 certification.

Frequently Asked Questions (FAQ)

Q: Are MDF7-12D-2.54DSA(55) and MDF7-12D-2.54DSA(95) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, pitch spacing (0.100"), row configuration, mounting type (through-hole), and fastening mechanism (push-pull). They are direct mechanical substitutes.

Q: Are the electrical ratings identical?

A: Yes. Both parts are rated for 3A current and 250VAC voltage with identical operating temperature ranges (-35°C ~ 85°C).

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

A: The primary difference is product status. MDF7-12D-2.54DSA(55) is obsolete, while MDF7-12D-2.54DSA(95) is active. The suffix designation (55 vs. 95) reflects this status change within the MDF7 series. RoHS compliance has been updated from RoHS Compliant to ROHS3 Compliant in the active variant.

Q: Can I use MDF7-12D-2.54DSA(95) in place of MDF7-12D-2.54DSA(55) in existing designs?

A: Yes. The substitute part maintains full compatibility with existing PCB layouts, mating connectors, and electrical specifications. No design modifications are required.

Q: What is the packaging difference?

A: MDF7-12D-2.54DSA(55) packaging is not specified. MDF7-12D-2.54DSA(95) is supplied in bag packaging. This does not affect functional compatibility.

Q: Are both parts RoHS compliant?

A: Yes. MDF7-12D-2.54DSA(55) is RoHS Compliant. MDF7-12D-2.54DSA(95) is ROHS3 Compliant, representing an updated compliance certification for the active product variant.
