MEC Switches 4ATH961 Equivalent & Substitute Parts

Part Overview

The MEC Switches 4ATH961 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 white LED illumination and IP67 ingress protection. The part is Active status and ROHS3 compliant, making it suitable for sealed applications requiring tactile feedback with visual indication.

Substitute parts become necessary when addressing inventory constraints, packaging requirements, or when design specifications allow for alternative mechanical characteristics within the same functional category.

Substitute Part Grouping Explanation

The MEC Switches 5GTH93561 qualifies as a direct substitute for the 4ATH961 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: Both LED, white
• Illumination voltage: Both 3.05 VDC nominal
• Ingress protection: Both IP67
• Termination style: Both PC pin
• Outline dimensions: Both 10.10mm x 10.10mm
• RoHS compliance: Both ROHS3 compliant
• Mechanical life: Both 10,000,000 cycles

Substitution is valid when design specifications do not impose constraints on the parameters that differ between these parts.

Parameter Comparison

Engineering Selection Recommendations

Both the 4ATH961 and 5GTH93561 are Active status components with identical RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on the following provided specifications:

Actuator height represents the primary dimensional difference. The 4ATH961 provides 8.40mm height, while the 5GTH93561 provides 6.40mm height. PCB layout constraints and enclosure clearance requirements determine which height is appropriate for the application.

Operating force differs at 300gf for the 4ATH961 versus 350gf for the 5GTH93561. Applications with specific tactile feedback requirements should account for this 50gf variance.

Operating temperature range extends to -40°C ~ 160°C for the 5GTH93561 compared to -30°C ~ 85°C for the 4ATH961. Extended temperature applications require the 5GTH93561.

Both parts maintain identical electrical ratings, illumination specifications, and mechanical life cycles, ensuring functional equivalence within their respective parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can the 5GTH93561 replace the 4ATH961 in all applications?

A: Substitution is valid when the design does not impose constraints on actuator height, operating force, or operating temperature range. The 5GTH93561 features a lower actuator height (6.40mm vs 8.40mm), higher operating force (350gf vs 300gf), and extended temperature range (-40°C ~ 160°C vs -30°C ~ 85°C). Verify these parameters against your PCB layout and environmental specifications before substitution.

Q: What are the key electrical parameters that must match for substitution?

A: Circuit configuration (SPST-NO), contact rating (0.05A @ 24VDC), illumination type (LED, white), and illumination voltage (3.05 VDC) must remain constant. Both parts meet these requirements identically.

Q: How do packaging differences affect component selection?

A: The 4ATH961 is supplied in standard packaging, while the 5GTH93561 is supplied in tube packaging. Packaging affects handling, storage, and assembly processes but does not impact electrical or mechanical function.

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

A: Yes. Both parts feature IP67 ingress protection and sealed flux protection, qualifying them for dust-tight and waterproof applications.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8536.50.9031. Moisture sensitivity level is 1 (unlimited) for both parts.
