68-position MDR versus 68-contact VHDCI

Is the 68-contact legacy interface MDR or the narrower VHDCI family?

How they differ

  • 68-position Mini Delta Ribbon (MDR) connector Confirm the MDR series and 68-contact variant from markings or component documentation; do not identify it from contact count alone.
  • 68-contact VHDCI SCSI connector Identify the narrow VHDCI shell and verify a documented VHDCI SCSI assembly rather than selecting by “68-pin SCSI” wording alone.

Then askIs the 68-contact legacy interface MDR or the narrower VHDCI family?

Key distinctionA 68-contact MDR shell is not the same mechanical family as VHDCI merely because both can expose 68 contacts.A 68-contact count does not make VHDCI interchangeable with MDR or other 68-position interfaces; shell and mating family must match.
