Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSL0M512 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically to establish a valid substitute relationship:

• Circuit configuration (SPST-NO)
• Contact rating (0.05A @ 32VDC)
• Switch function (Off-Mom)
• Mounting type (Through Hole)
• Actuator height (9.90mm)
• Outline dimensions (7.40mm x 7.40mm)
• Operating force (500gf)
• Ingress protection rating (IP65)
• Operating temperature range (-40°C ~ 90°C)
• Switch travel (0.70mm)
• Mechanical life (100,000 Cycles)
• Termination style (PC Pin)
• Series designation (KSL MKII)

The KSL0M512LFT meets all these criteria and qualifies as a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The KSL0M512LFT is the direct substitute for the obsolete KSL0M512. Both components are electrically and mechanically identical across all specified parameters, ensuring pin-for-pin and functional compatibility in existing designs.

A key distinction exists in regulatory compliance: the KSL0M512LFT carries ROHS3 compliance, whereas the KSL0M512 is RoHS non-compliant. For applications subject to RoHS directives or equivalent environmental regulations, the KSL0M512LFT is the appropriate selection. Both components maintain identical REACH and ECCN classifications.

The KSL0M512LFT is currently in active production status with significantly higher inventory availability (5311 pieces) compared to the obsolete KSL0M512 (827 pieces). For new designs or ongoing production requirements, the KSL0M512LFT is the recommended selection.
