MEC Switches 4ATH982 Equivalent & Substitute Parts

Part Overview

The 4ATH982 is an illuminated tactile switch from MEC Switches' Multimec® 4 series, designed for applications requiring momentary contact switching at 0.05A 24VDC. This SPST-NO (Single Pole Single Throw - Normally Open) switch features top actuation, through-hole mounting, and integrated red LED illumination with IP67 ingress protection. The part is currently active in production with 1062 units in stock.

Identifying equivalent and substitute parts is necessary when addressing supply chain constraints, design revisions requiring different actuator heights, or when transitioning between product series while maintaining functional compatibility.

Substitute Part Grouping Explanation

The 5GTH93582 qualifies as a direct substitute for the 4ATH982 based on the following critical parameters:

• Circuit Configuration: Both parts are SPST-NO with identical contact ratings (0.05A @ 24VDC)
• Switch Function: Both operate as momentary (Off-Mom) switches
• Mounting & Termination: Identical through-hole mounting with PC pin termination
• Outline Dimensions: Both measure 10.10mm x 10.10mm, ensuring PCB footprint compatibility
• Actuator Orientation: Both feature top actuation
• Illumination: Both include red LED illumination at 2VDC nominal
• Ingress Protection: Both maintain IP67 sealing
• Switch Travel: Both have 1.00mm travel distance
• Mechanical Life: Both rated for 10,000,000 cycles
• Compliance: Both are ROHS3 compliant with REACH unaffected status

The 5GTH93582 represents an evolution within the Multimec® product family (series 5 versus series 4), offering improved specifications while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the 4ATH982 and 5GTH93582 are active production parts with full ROHS3 compliance and REACH unaffected status, making either suitable for new designs and production applications.

The 5GTH93582 offers an extended operating temperature range (-40°C to 160°C versus -30°C to 85°C), making it the preferred choice for applications subject to extreme thermal conditions. The higher operating force (350gf versus 300gf) may be relevant for applications requiring increased tactile feedback or resistance to accidental actuation.

The primary design consideration is actuator height: the 4ATH982 provides 8.40mm height while the 5GTH93582 provides 6.40mm height. This 2.00mm difference must be evaluated against enclosure geometry and user interface requirements. Both parts maintain identical PCB footprint dimensions and electrical characteristics, ensuring straightforward substitution at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can the 5GTH93582 be used as a direct replacement for the 4ATH982 in existing designs?

A: Yes, provided the 2.00mm difference in actuator height does not conflict with enclosure constraints or user interface specifications. All electrical parameters, mounting footprint, and functional characteristics are identical.

**Q: What is the significance of the different operating force ratings?

A: The 4ATH982 requires 300gf of force to actuate, while the 5GTH93582 requires 350gf. This difference affects tactile feedback and resistance to unintended activation. Select based on application ergonomics and environmental conditions.

Q: Are there packaging differences between these parts?

A: The 4ATH982 uses standard packaging while the 5GTH93582 is supplied in tube packaging. This affects handling, storage, and automated assembly processes but does not impact electrical or mechanical function.

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

A: The 5GTH93582 is rated for -40°C to 160°C operation, compared to the 4ATH982's -30°C to 85°C range. For applications exceeding 85°C, the 5GTH93582 is the appropriate selection.

Q: Do both parts maintain the same illumination specifications?

A: Yes. Both feature red LED illumination at 2VDC nominal voltage with identical brightness and color characteristics.

Q: What is the mechanical life expectancy for both parts?

A: Both the 4ATH982 and 5GTH93582 are rated for 10,000,000 mechanical cycles, providing equivalent durability for high-cycle applications.
