Substitute Part Grouping Explanation

Substitution of the 794681-8 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

  • Connector type (Header)
  • Contact type (Male Pin)
  • Number of positions (8)
  • Number of rows (2)
  • Pitch spacing (0.118" / 3.00mm)
  • Row spacing (0.118" / 3.00mm)
  • Mounting type (Through Hole)
  • Shrouding configuration (Shrouded - 4 Wall)
  • Fastening type (Locking Ramp)

Electrical Compatibility Parameters:

  • Voltage rating (250V)
  • Operating temperature range (-40°C ~ 105°C)
  • Contact material (Brass)
  • Contact finish - mating surface (Gold)

Termination Parameters:

  • Termination method (Solder)
  • Contact post finish material and thickness

The substitute part 3-794681-8 maintains full equivalence across all mechanical and electrical parameters. The primary differences are product status (Active vs. Obsolete) and packaging format (Tray vs. standard packaging), along with minor contact finish post material variation (Tin vs. Tin-Lead) and regulatory compliance status.
