APEM Inc. 3CTL9 Tactile Switch SPST-NO Equivalent & Substitute Parts

Part Overview

The APEM Inc. 3CTL9 is a tactile switch with SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration, rated for 0.05A at 24VDC. This component features top actuation, through-hole mounting, and sealed construction with IP67 ingress protection. The 3CTL9 is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3CTL9 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Contact rating (0.05A @ 24VDC)
• Mounting type (Through Hole)
• Actuator orientation (Top Actuated)
• Physical outline (10.10mm x 10.10mm)
• Ingress protection level (IP67)
• Termination style (PC Pin)
• Switch travel (1.00mm)
• Operating force (300gf)

The 3CTH9G qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions, and functional characteristics. Variations in actuator material, operating temperature range, and product status do not preclude substitution when electrical and mechanical compatibility is maintained.

Parameter Comparison

Engineering Selection Recommendations

The 3CTH9G is the direct substitute for the obsolete 3CTL9. Both components maintain identical electrical ratings, mechanical dimensions, and functional specifications within the Multimec® 3 series. The 3CTH9G carries active product status, ensuring ongoing availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The 3CTH9G features an extended operating temperature range (-40°C to 160°C versus -40°C to 115°C) and uses Polyphenylene Sulfide (PPS) actuator material in place of Polybutylene Terephthalate (PBT), providing enhanced thermal stability without compromising electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 3CTH9G be used as a direct replacement for the 3CTL9 in existing designs?

A: Yes. The 3CTH9G maintains identical electrical specifications (0.05A @ 24VDC), circuit configuration (SPST-NO), mechanical dimensions (10.10mm x 10.10mm), and mounting characteristics (through-hole, top actuated). Pin-for-pin compatibility is confirmed.

Q: What is the primary difference between these two parts?

A: The 3CTL9 is obsolete; the 3CTH9G is active. The 3CTH9G features an extended operating temperature range and uses PPS actuator material instead of PBT. These differences do not affect electrical or mechanical substitution.

Q: Are there packaging differences between the 3CTL9 and 3CTH9G?

A: The 3CTL9 is supplied in standard packaging; the 3CTH9G is supplied in tray packaging. Both configurations are suitable for through-hole assembly processes.

Q: Do both parts meet current compliance standards?

A: Yes. Both the 3CTL9 and 3CTH9G are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the mechanical life expectancy for these switches?

A: Both parts are rated for 10,000,000 mechanical cycles, providing equivalent durability and operational lifespan.
