Substitute Part Grouping Explanation

Substitution of the KSA0M212 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

• Circuit configuration (SPST-NO)
• Switch function (Off-Mom momentary operation)
• Contact rating (0.05A @ 32VDC)
• Mounting method (Through Hole)
• Actuator orientation (Top Actuated)
• Physical dimensions (6.20mm x 6.20mm outline, 4.70mm height)
• Operating force (130gf)
• Switch travel distance (0.50mm)
• Ingress protection rating (IP65)
• Operating temperature range (-40°C ~ 85°C)
• Mechanical life specification (100,000 Cycles)
• Termination style (PC Pin)

The KSA0M212LFT is classified as a direct substitute based on complete parameter alignment across all specified electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The KSA0M212LFT is the direct substitute for the obsolete KSA0M212. Both components are electrically and mechanically identical across all specified parameters. The primary distinction is product status and regulatory compliance.

The KSA0M212LFT offers the following advantages:

• Active product status ensures ongoing availability and manufacturer support
• ROHS3 compliance satisfies current regulatory requirements for new designs and production
• Identical electrical performance and mechanical specifications ensure drop-in compatibility
• Same series designation (KSA MKII) confirms design continuity

For applications currently using the KSA0M212, transition to the KSA0M212LFT is supported by complete parameter equivalence. No circuit redesign or PCB layout modification is required.
