MEC Switches 4ASH982 Equivalent & Substitute Parts

Part Overview

The 4ASH982 is an illuminated tactile switch from MEC Switches' Multimec® 4 series, designed for surface mount applications requiring SPST-NO (Single Pole Single Throw - Normally Open) switching functionality. This component operates at 0.05A @ 24VDC with IP67 ingress protection, making it suitable for sealed, dust-tight and waterproof applications. The part is currently Active in production status with 756 units in stock. Substitute parts become necessary when design requirements demand alternative mechanical characteristics, extended operating temperature ranges, or different series specifications while maintaining core electrical and functional compatibility.

Substitute Part Grouping Explanation

The 5GSH93582 qualifies as a direct substitute for the 4ASH982 based on matching core electrical and functional parameters: identical SPST-NO circuit configuration, 0.05A @ 24VDC contact rating, momentary switch function, surface mount termination, top actuated orientation, 10.10mm x 10.10mm footprint, red LED illumination at 2VDC nominal, IP67 ingress protection, 1.00mm switch travel, and 10,000,000 cycle mechanical life rating. Both parts are ROHS3 compliant and REACH unaffected. Substitution is valid when the following mechanical and environmental differences are acceptable: the 5GSH93582 features a reduced actuator height (6.40mm vs 8.40mm), increased operating force (350gf vs 300gf), and an extended operating temperature range (-40°C ~ 160°C vs -30°C ~ 85°C). The 5GSH93582 belongs to the newer Multimec® 5 series and is supplied in tube packaging versus the 4ASH982's standard packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the 4ASH982 and 5GSH93582 maintain Active product status with full ROHS3 compliance and REACH unaffected certification, ensuring regulatory compliance for current and future applications. Selection between these parts should be based on specific design constraints:

The 4ASH982 is appropriate for applications with standard operating temperature requirements (-30°C ~ 85°C) and lower actuator force tolerance (300gf). The 5GSH93582 is suitable for designs requiring extended temperature operation (-40°C ~ 160°C), higher actuator force specification (350gf), or reduced actuator height (6.40mm vs 8.40mm) for space-constrained PCB layouts. Both parts share identical electrical ratings, footprint dimensions, and mechanical life specifications, ensuring functional interchangeability within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can the 5GSH93582 be used as a direct replacement for the 4ASH982 in existing designs?

A: Yes, provided the design accommodates the mechanical differences. The 5GSH93582 has a lower actuator height (6.40mm vs 8.40mm) and higher operating force (350gf vs 300gf). Verify that your enclosure design and user interface requirements accept these changes. Electrical and functional specifications are identical.

Q: What is the primary difference between the Multimec® 4 and Multimec® 5 series?

A: The 5GSH93582 from the Multimec® 5 series offers an extended operating temperature range (-40°C ~ 160°C) compared to the Multimec® 4 series 4ASH982 (-30°C ~ 85°C). The Multimec® 5 also features a lower profile actuator design.

Q: Are there packaging differences between these parts?

A: Yes. The 4ASH982 uses standard packaging, while the 5GSH93582 is supplied in tube packaging. Verify compatibility with your assembly and handling processes.

Q: Do both parts maintain the same footprint for PCB layout?

A: Yes. Both parts have identical outline dimensions of 10.10mm x 10.10mm and use gull wing termination, ensuring PCB layout compatibility.

Q: What operating force difference should I consider for user interface design?

A: The 5GSH93582 requires 350gf actuator force compared to 300gf for the 4ASH982. This 50gf increase may be perceptible to end users and should be evaluated for tactile feedback consistency in your application.

Q: Are both parts suitable for sealed, waterproof applications?

A: Yes. Both parts carry IP67 ingress protection rating and sealed flux protection features, making them suitable for dust-tight and waterproof applications.
