Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across all critical mechanical and electrical parameters. The following parameters establish the substitution criteria for the 794466-2:

Mechanical Compatibility Parameters:

  • Connector type (Header)
  • Contact type (Male Pin)
  • Number of positions (4)
  • Number of rows (2)
  • Pitch - mating (0.165" / 4.20mm)
  • Row spacing - mating (0.165" / 4.20mm)
  • Mounting type (Through Hole)
  • Shrouding configuration (Shrouded - 4 Wall)
  • Fastening type (Locking Ramp)
  • Insulation height (0.504" / 12.80mm)
  • Contact shape (Square)

Electrical Compatibility Parameters:

  • Voltage rating (600VAC)
  • Operating temperature range (-55°C ~ 105°C)
  • Material flammability rating (UL94 V-0)

Material Specifications:

  • Insulation material (Polyamide / Nylon)
  • Contact material (Copper Alloy)
  • Contact finish - mating (Gold)

Parts meeting all these criteria are classified as direct substitutes. Variations in contact finish post material (Tin-Lead versus Tin) and product status (Obsolete versus Active) do not affect functional substitution capability.

Engineering Selection Recommendations

The 1-794466-2 is a direct functional equivalent to the 794466-2 across all critical mechanical and electrical parameters. Both connectors share identical specifications for connector type, contact configuration, pitch, mounting method, shrouding, fastening mechanism, insulation dimensions, and electrical ratings.

The primary distinction between these parts is product status and regulatory compliance. The 794466-2 is classified as obsolete with RoHS non-compliant status, while the 1-794466-2 is active and RoHS compliant. The 1-794466-2 also carries REACH Unaffected designation compared to the vendor-undefined status of the original part.

A secondary difference exists in the contact finish post material: the 794466-2 uses Tin-Lead while the 1-794466-2 uses Tin. This variation reflects modern manufacturing standards and does not affect functional compatibility or performance within the specified operating parameters.

For applications requiring active product availability, regulatory compliance, or new design implementations, the 1-794466-2 is the appropriate selection. The part maintains full mechanical and electrical interchangeability with the obsolete 794466-2.

Frequently Asked Questions (FAQ)
