Substitute Part Grouping Explanation

Substitution of the ITS60FR3SR is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary contact)
• Contact rating: 0.05A @ 12VDC
• Mounting type: Surface Mount, Right Angle
• Actuator orientation: Side Actuated
• Termination style: SMD (SMT) Tab
• Outline dimensions: 6.70mm x 4.00mm
• Illumination: LED, Green at 3.6 VDC nominal
• Operating force: 220gf
• Operating temperature range: -25°C ~ 70°C
• Switch travel: 0.25mm
• Mechanical life: 50,000 Cycles
• Actuator material: Polyamide (PA), Nylon

The ITS60FR3NSR qualifies as a direct substitute based on complete alignment with all specified electrical, mechanical, and physical parameters. The primary distinction is product status: ITS60FR3NSR is active production, whereas ITS60FR3SR is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The ITS60FR3NSR is the direct equivalent substitute for the obsolete ITS60FR3SR. Both components share identical electrical specifications, mechanical characteristics, and physical dimensions. The ITS60FR3NSR maintains full compatibility with existing PCB layouts and circuit designs.
