MEC Switches 3ATL6 Tactile Switch SPST-NO Equivalent & Substitute Parts

Part Overview

The MEC Switches 3ATL6 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 part is currently obsolete, making identification of compatible substitute components essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3ATL6 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)
• Actuator height off PCB (6.40mm)
• Switch travel (1.00mm)
• Ingress protection rating (IP67)
• Termination style (PC Pin)
• Mechanical life rating (10,000,000 Cycles)
• Regulatory compliance (ROHS3 Compliant)

The MEC Switches 5GTH935 meets all substitution criteria as a direct equivalent component from the same manufacturer, with enhanced specifications in operating temperature range and actuator material composition.

Parameter Comparison

Engineering Selection Recommendations

The 5GTH935 is a direct functional equivalent to the obsolete 3ATL6. Both components maintain identical electrical ratings, mechanical dimensions, and ingress protection specifications. The 5GTH935 is currently in active production status, ensuring supply chain continuity and long-term availability.

The 5GTH935 offers enhanced operating temperature range (-40°C to 160°C versus -40°C to 115°C) and upgraded actuator material composition (Polyphenylene Sulfide versus Polybutylene Terephthalate), providing improved thermal stability and chemical resistance. Both parts carry equivalent regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99).

The operating force differential (350gf versus 300gf) represents a minor specification variance within the same product family and does not affect functional compatibility for standard applications.

Frequently Asked Questions (FAQ)

Q: Can the 5GTH935 be used as a direct replacement for the 3ATL6 in existing designs?

A: Yes. The 5GTH935 maintains identical electrical ratings (0.05A @ 24VDC), circuit configuration (SPST-NO), physical dimensions (10.10mm x 10.10mm), actuator height (6.40mm), and ingress protection rating (IP67). PCB footprint and mounting compatibility are preserved.

Q: What are the differences between the 3ATL6 and 5GTH935?

A: The primary differences are product status (obsolete versus active), operating temperature range (-40°C to 115°C versus -40°C to 160°C), actuator material (PBT versus PPS), and operating force (300gf versus 350gf). All critical electrical and mechanical parameters remain equivalent.

Q: Does the higher operating force of the 5GTH935 affect compatibility?

A: The 50gf increase in operating force (from 300gf to 350gf) is a minor specification variance within the Multimec product family. This does not compromise functional compatibility for standard tactile switch applications.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 3ATL6 and 5GTH935 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What packaging is available for the 5GTH935?

A: The 5GTH935 is supplied in Tube packaging, with 23,969 pieces currently in stock.
