Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors is determined by strict equivalence across mechanical and electrical parameters. The following criteria establish substitutability for the 536279-2:

Critical Matching Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (60)
• Mating pitch (0.050" / 1.27mm)
• Number of rows (2)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact finish - mating (Gold)
• Operating temperature range (-65°C ~ 125°C)
• Voltage rating (30VAC)
• Series designation (Micro-Strip)
• Style (Board to Board)

Variations in post finish material, product status, and regulatory compliance do not affect mechanical or electrical interchangeability when all critical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5536279-2 is a direct functional equivalent to the 536279-2 across all critical mechanical and electrical parameters. Both connectors share identical mating pitch, row configuration, contact geometry, operating temperature range, and voltage rating.
