Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSA0M512 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
• Actuator height: 4.70mm
• Outline dimensions: 6.20mm x 6.20mm
• Operating force: 500gf
• Ingress protection: IP65
• Operating temperature range: -40°C ~ 85°C
• Switch travel: 0.70mm
• Mechanical life: 100,000 Cycles
• Termination style: PC Pin
• Series: KSA MKII

The KSA0M512LFT meets all these criteria and is classified as a direct substitute. The primary distinction between these parts is product status and packaging configuration, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The KSA0M512LFT is the direct functional equivalent of the KSA0M512. Both parts share identical electrical and mechanical specifications across all critical parameters. The KSA0M512LFT is the preferred selection for new designs and ongoing production due to its active product status and ROHS3 compliance. The KSA0M512 is obsolete and should be replaced with the KSA0M512LFT in all applications where component availability and regulatory compliance are considerations.
