Substitute Part Grouping Explanation

The 3M 155206-5202-RB qualifies as a direct substitute for the 155206-5302-RB based on identical electrical and mechanical parameters. Both connectors share the same base product number (155206) and series designation (1552), confirming design compatibility within the 3M connector family.

Substitution is valid based on the following matching parameters:

• Connector type, contact type, and contact configuration (6-position, 2-row header with male pins)
• Pitch specifications (0.079" mating pitch and row spacing)
• Mounting method (through-hole, right-angle orientation)
• Shrouding design (4-wall shrouded construction)
• Contact materials and finishes (copper alloy with gold mating surface and tin post finish)
• Insulation material and flammability rating (LCP glass-filled, UL94 V-0)
• Operating temperature range (-55°C ~ 105°C)
• Current rating (1.25A)

The primary distinction between these parts is product status: 155206-5302-RB is obsolete, while 155206-5202-RB is active. The substitute part includes RoHS compliance certification, reflecting current manufacturing standards.

Parameter Comparison

Engineering Selection Recommendations

The 3M 155206-5202-RB is the direct functional equivalent for the obsolete 155206-5302-RB. Selection of the substitute part is based on:
