MEC Switches 3ATL6Q Tactile Switch - Equivalent & Substitute Parts

Part Overview

The MEC Switches 3ATL6Q is a tactile switch with SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration, rated for 0.05A at 24VDC. This through-hole mounted component features a top-actuated plunger design with sealed construction for IP67 ingress protection. The 3ATL6Q is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The 3ATH9Q serves as a direct substitute for the 3ATL6Q based on matching electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Circuit configuration: SPST-NO (identical)
• Contact rating: 0.05A @ 24VDC (identical)
• Mounting type: Through Hole (identical)
• Actuator height: 6.40mm (identical)
• Outline dimensions: 10.10mm x 10.10mm (identical)
• Operating force: 300gf (identical)
• Switch travel: 1.00mm (identical)
• Ingress protection: IP67 (identical)
• Termination style: PC Pin (identical)

The 3ATH9Q is classified as Active product status, providing ongoing availability and supply chain continuity for applications currently using the obsolete 3ATL6Q.

Parameter Comparison

Engineering Selection Recommendations

The 3ATH9Q is the appropriate substitute for the obsolete 3ATL6Q. Both components maintain identical electrical specifications, mechanical dimensions, and contact ratings. The 3ATH9Q offers an extended operating temperature range (-40°C to 160°C versus -40°C to 115°C) and uses polyphenylene sulfide actuator material instead of polybutylene terephthalate, providing enhanced thermal stability. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The 3ATH9Q's active product status ensures continued availability and supply chain support.

Frequently Asked Questions (FAQ)

Q: Can the 3ATH9Q directly replace the 3ATL6Q in existing designs?

A: Yes. The 3ATH9Q maintains identical electrical ratings (0.05A @ 24VDC), circuit configuration (SPST-NO), mechanical dimensions (10.10mm x 10.10mm), actuator height (6.40mm), operating force (300gf), and switch travel (1.00mm). Through-hole mounting and PC pin termination are identical. Both components provide IP67 ingress protection.

Q: What are the differences between these two parts?

A: The primary differences are product status (3ATL6Q is obsolete; 3ATH9Q is active), operating temperature range (3ATH9Q extends to 160°C versus 115°C for 3ATL6Q), actuator material composition (PPS versus PBT), and packaging (3ATH9Q supplied in tube format).

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Both are classified under ECCN EAR99 and HTSUS 8536.50.9031.

Q: What is the impact of the different actuator materials?

A: The 3ATH9Q uses polyphenylene sulfide (PPS) actuator material, which provides improved thermal stability compared to the polybutylene terephthalate (PBT) material in the 3ATL6Q. This material change supports the extended operating temperature range of the 3ATH9Q.

Q: Should packaging format be considered in the substitution decision?

A: Packaging format (tube for 3ATH9Q) does not affect electrical or mechanical compatibility. Selection should be based on procurement and assembly process requirements.
