MEC Switches 4ASH922 Equivalent & Substitute Parts

Part Overview

The 4ASH922 is an illuminated tactile switch from MEC Switches' Multimec® 4 series, designed for surface mount applications requiring sealed, waterproof operation. This SPST-NO (Single Pole Single Throw - Normally Open) switch is rated for 0.05A at 24VDC with an integrated green LED indicator and IP67 ingress protection. The part is currently active in production with 834 units in stock. Alternative models may be required due to design revisions, availability constraints, or specific application requirements for different actuator heights or operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

The 5GSH93522 qualifies as a direct substitute for the 4ASH922 based on the following critical parameters that determine functional interchangeability:

• Circuit Configuration: Both parts are SPST-NO with identical switch function (Off-Mom)
• Contact Rating: Both rated 0.05A @ 24VDC
• Mounting Type: Both are surface mount with gull wing termination
• Outline Dimensions: Both measure 10.10mm x 10.10mm
• Illumination: Both feature illuminated green LED at 2.2 VDC nominal
• Ingress Protection: Both provide IP67 sealing
• Actuator Material: Both use Polyphenylene Sulfide (PPS)
• Switch Travel: Both have 1.00mm travel distance
• Mechanical Life: Both rated for 10,000,000 cycles
• Compliance: Both are ROHS3 compliant and REACH unaffected

Differences exist in actuator height (8.40mm vs. 6.40mm), operating force (300gf vs. 350gf), operating temperature range (-30°C ~ 85°C vs. -40°C ~ 160°C), and series designation (Multimec® 4 vs. Multimec® 5). These differences do not prevent substitution when the application tolerates the specified variations.

Parameter Comparison

Engineering Selection Recommendations

Both the 4ASH922 and 5GSH93522 are active production parts with full ROHS3 compliance and REACH unaffected status, making either suitable for new designs and production environments. The 5GSH93522 offers an extended operating temperature range (-40°C ~ 160°C versus -30°C ~ 85°C), which may be advantageous for applications requiring broader thermal performance. The 4ASH922 features a taller actuator profile (8.40mm versus 6.40mm), which may be preferred for applications requiring greater tactile feedback distance or specific mechanical clearance requirements. Selection should be based on PCB layout constraints, actuator height requirements, and thermal operating conditions specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 5GSH93522 be used as a direct replacement for the 4ASH922 in existing designs?

A: Yes, the 5GSH93522 is functionally compatible as a substitute. Both parts share identical electrical ratings (0.05A @ 24VDC), circuit configuration (SPST-NO), mounting type (surface mount), outline dimensions (10.10mm x 10.10mm), and illumination specifications (green LED, 2.2 VDC). PCB layout compatibility is maintained through identical gull wing termination and outline footprint.

Q: What are the key differences between these two parts?

A: The primary differences are actuator height (8.40mm for 4ASH922 versus 6.40mm for 5GSH93522), operating force (300gf versus 350gf), and operating temperature range (-30°C ~ 85°C versus -40°C ~ 160°C). The 5GSH93522 belongs to the Multimec® 5 series while the 4ASH922 is from the Multimec® 4 series.

Q: Does the difference in actuator height affect PCB design?

A: The 2.00mm difference in actuator height may impact mechanical clearance above the PCB. Applications with tight vertical space constraints should verify that the substitute part's actuator height is compatible with the enclosure or overlay design.

Q: Are both parts available in the same packaging?

A: The 4ASH922 is available in standard packaging, while the 5GSH93522 is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Which part should I select for high-temperature applications?

A: The 5GSH93522 supports an extended operating temperature range up to 160°C, making it suitable for high-temperature environments. The 4ASH922 is rated to 85°C maximum.

Q: Are both parts RoHS and REACH compliant?

A: Yes, both the 4ASH922 and 5GSH93522 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
