Key Parameters

Substitute Part Grouping Explanation

The M80-4122042 qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Identical connector type (Receptacle) and contact type (Female Socket)
• Matching position count (20 positions) and pitch specification (0.079" / 2.00mm)
• Identical row configuration (2 rows) and row spacing (0.079" / 2.00mm)
• Same mounting method (Surface Mount) and termination type (Solder)
• Matching mating contact finish (Gold) and finish thickness (12.0µin / 0.30µm)
• Identical insulation material (Polyphenylene Sulfide, Glass Filled) and color (Black)
• Same operating temperature range (-55°C ~ 125°C) and voltage rating (120V)
• Equivalent mechanical dimensions (Mated Stacking Heights: 7.7mm, 7.95mm)
• Identical features (Mating Flange, Polarizing Key)

The primary distinction is the post contact finish: M80-4122001 uses tin-lead plating while M80-4122042 uses tin plating, along with M80-4122042 being active product status with RoHS3 compliance.
