MEC Switches 4ATH942 Equivalent & Substitute Parts

Part Overview

The MEC Switches 4ATH942 is an illuminated tactile switch with SPST-NO circuit configuration, rated for 0.05A at 24VDC. This through-hole mounted component features a top-actuated plunger design with yellow LED illumination and IP67 ingress protection. The part is Active status and ROHS3 compliant, making it suitable for industrial and commercial applications requiring sealed, waterproof switching functionality.

Substitute parts become necessary when addressing inventory constraints, extended lead times, or when design specifications allow for alternative configurations within the same functional category while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The 5GTH93542 qualifies as a direct substitute for the 4ATH942 based on the following matching parameters:

• Circuit configuration: Both SPST-NO
• Contact rating: Both 0.05A @ 24VDC
• Mounting type: Both through-hole
• Actuator orientation: Both top-actuated
• Illumination type and voltage: Both LED yellow at 2 VDC
• Ingress protection: Both IP67
• Termination style: Both PC pin
• Outline dimensions: Both 10.10mm x 10.10mm
• Switch travel: Both 1.00mm
• Mechanical life: Both 10,000,000 cycles
• Compliance: Both ROHS3 compliant, REACH unaffected

The 5GTH93542 represents a newer generation (Multimec® 5 series) variant of the 4ATH942 (Multimec® 4 series) with controlled parameter variations that do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 4ATH942 and 5GTH93542 maintain Active product status and full ROHS3 compliance with REACH unaffected designation. Selection between these parts should be based on the following provided specifications:

The 5GTH93542 offers an extended operating temperature range (-40°C to 160°C versus -30°C to 85°C), making it suitable for applications requiring broader thermal performance. The 5GTH93542 features a reduced actuator height of 6.40mm compared to 8.40mm on the 4ATH942, which may be relevant for space-constrained PCB layouts. The 5GTH93542 has a higher operating force specification (350gf versus 300gf), which affects tactile feedback characteristics.

Both parts share identical electrical ratings, mechanical life, ingress protection, and dimensional footprint, supporting direct substitution in standard applications where the noted parameter differences do not conflict with design requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5GTH93542 directly replace the 4ATH942 in existing designs?

A: Yes, for applications where the parameter differences do not create constraints. The 5GTH93542 has a lower actuator height (6.40mm vs 8.40mm) and higher operating force (350gf vs 300gf). Verify that your PCB layout accommodates the reduced height and that the increased actuation force is acceptable for your user interface requirements.

Q: What is the significance of the actuator height difference?

A: The 5GTH93542 has a 2.00mm lower actuator height. This affects the vertical clearance required above the PCB and may influence the design of any protective caps or overlays used with the switch.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts are rated for 0.05A @ 24VDC, feature SPST-NO circuits, identical switch travel (1.00mm), and identical mechanical life (10,000,000 cycles). Illumination specifications are also identical: LED yellow at 2 VDC nominal.

Q: What packaging differences exist?

A: The 4ATH942 is supplied in standard packaging, while the 5GTH93542 is supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Which part should be selected for high-temperature applications?

A: The 5GTH93542 supports an extended operating temperature range of -40°C to 160°C, compared to -30°C to 85°C for the 4ATH942. For applications exceeding 85°C, the 5GTH93542 is the appropriate selection.

Q: Are both parts RoHS compliant?

A: Yes. Both the 4ATH942 and 5GTH93542 are ROHS3 compliant with REACH unaffected status, meeting current environmental and regulatory requirements.
