MEC Switches 4ASH98222 Equivalent & Substitute Parts

Part Overview

The 4ASH98222 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 IP67 ingress protection and LED illumination in green/red. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified when design requirements allow for variations in specific mechanical or electrical parameters while maintaining core functional compatibility for the intended application.

Key Parameters

Substitute Part Grouping Explanation

The 5GSH9358222 qualifies as a direct substitute for the 4ASH98222 based on the following matching parameters:

• Circuit configuration: Both are SPST-NO
• Contact rating: Both rated 0.05A @ 24VDC
• Mounting type: Both surface mount with gull wing termination
• Outline dimensions: Both 10.10mm x 10.10mm
• Illumination: Both feature LED illumination in green/red with 2.0, 2.2 VDC nominal voltage
• Ingress protection: Both IP67 sealed and waterproof
• Switch travel: Both 1.00mm
• Mechanical life: Both 10,000,000 cycles
• Compliance: Both ROHS3 compliant with MSL 1 (unlimited)

Variations between the parts are limited to series designation (Multimec® 4 vs. Multimec® 5), actuator height (8.40mm vs. 6.40mm), operating force (300gf vs. 350gf), and operating temperature range (-30°C ~ 85°C vs. -40°C ~ 160°C). These differences do not affect substitution eligibility when the application requirements fall within the overlapping specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 4ASH98222 and 5GSH9358222 are active production parts with identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Selection between these parts depends on application-specific requirements:

The 4ASH98222 operates within -30°C to 85°C and features an 8.40mm actuator height with 300gf operating force. The 5GSH9358222 extends the operating temperature range to -40°C to 160°C with a lower 6.40mm actuator height and higher 350gf operating force. Both parts maintain identical electrical ratings, mechanical life, and IP67 sealing characteristics.

For applications requiring extended temperature operation or reduced actuator profile, the 5GSH9358222 is suitable. For applications with standard temperature requirements and preference for lower actuation force, the 4ASH98222 remains appropriate. PCB layout constraints related to actuator height should be evaluated during design phase.

Frequently Asked Questions (FAQ)

Q: Can the 5GSH9358222 replace the 4ASH98222 in existing designs?

A: Yes, provided the application requirements fall within the overlapping specifications. The 6.40mm actuator height of the 5GSH9358222 is lower than the 4ASH98222's 8.40mm height, which may affect mechanical clearance. The higher operating force (350gf vs. 300gf) and extended temperature range (-40°C ~ 160°C vs. -30°C ~ 85°C) should be evaluated against design requirements.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Both parts are rated 0.05A @ 24VDC with SPST-NO circuit configuration, identical switch travel (1.00mm), mechanical life (10,000,000 cycles), and LED illumination specifications (green/red, 2.0, 2.2 VDC nominal).

Q: What is the difference in packaging between these parts?

A: The 4ASH98222 is supplied in standard packaging, while the 5GSH9358222 is supplied in tube packaging. Both are surface mount gull wing termination components with identical outline dimensions (10.10mm x 10.10mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, MSL 1 (unlimited), and classified as EAR99 for export purposes. Both carry identical HTSUS code 8536.50.9031.

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

A: The 5GSH9358222 is rated for -40°C to 160°C operation, providing extended upper temperature capability compared to the 4ASH98222's -30°C to 85°C range. Selection should be based on specific application temperature requirements.
