Key Parameters

Substitute Part Grouping Explanation

Substitution for the KSA0V511LFT is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Switch function (Off-Mom momentary operation)
• Contact rating (0.05A @ 32VDC)
• Mounting type (Through Hole, Right Angle)
• Actuator orientation (Side Actuated)
• Physical outline (8.00mm x 8.00mm)
• Actuator length (3.23mm)
• Operating force (500gf)
• Switch travel (0.70mm)
• Mechanical life (100,000 Cycles)
• Operating temperature range (-40°C ~ 90°C)
• Ingress protection (IP60)
• Termination style (PC Pin)
• Compliance certifications (ROHS3, REACH Unaffected)

The substitute part KSA0V511 LFTR maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The KSA0V511 LFTR is a direct functional equivalent to the KSA0V511LFT. Both parts are manufactured by C&K within the KSA series and maintain identical electrical specifications, mechanical dimensions, and performance characteristics. The primary distinction is product status: the KSA0V511LFT is discontinued, while the KSA0V511 LFTR maintains active status with confirmed inventory availability.

Both parts satisfy ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications in consumer electronics, industrial control systems, and telecommunications equipment. The identical contact rating (0.05A @ 32VDC), operating temperature range (-40°C ~ 90°C), and mechanical life (100,000 cycles) confirm full interchangeability for circuit design and PCB layout purposes.
