Key Parameters

Substitute Part Grouping Explanation

The 3FTH924 qualifies as a direct substitute for the 3FTL624 based on matching electrical and mechanical parameters. Substitution eligibility is determined by the following critical parameters:

• Circuit configuration: Both parts are SPST-NO
• Contact rating: Both rated 0.05A @ 24VDC
• Actuator type and orientation: Both feature top-actuated plunger design
• Mounting configuration: Both are through-hole mounted
• Physical dimensions: Identical outline (10.10mm x 10.10mm) and actuator height (10.40mm)
• Illumination specification: Both feature green LED @ 2VDC
• Mechanical characteristics: Matching operating force (300gf), switch travel (1.00mm), and mechanical life (10,000,000 cycles)
• Environmental rating: Both provide IP67 ingress protection
• Termination: Both use PC Pin termination

The primary distinction between these parts is product status and operating temperature range, with the 3FTH924 offering extended temperature capability and active availability.

Parameter Comparison

Engineering Selection Recommendations

The 3FTH924 is the appropriate substitute for the obsolete 3FTL624. Both parts maintain identical electrical specifications, mechanical dimensions, and environmental ratings. The 3FTH924 provides extended operating temperature range (-40°C to 160°C versus -40°C to 115°C) and maintains active product status with current manufacturing availability. Both parts carry ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The substitution is direct for applications requiring the specified electrical and mechanical characteristics without modification to PCB layout or circuit design.

Frequently Asked Questions (FAQ)
