The 5GSH93501 belongs to the Multimec® 5 series and introduces variations in three parameters: reduced actuator height (6.40mm vs 8.40mm), increased operating force (350gf vs 300gf), and extended operating temperature range (-40°C ~ 160°C vs -30°C ~ 85°C).

Parameter Comparison

Engineering Selection Recommendations

Both the 4ASH901 and 5GSH93501 maintain active product status and full ROHS3 compliance. Selection between these parts depends on specific application requirements:

The 4ASH901 is suitable for applications with standard actuator height requirements of 8.40mm and operating conditions within -30°C to 85°C.

The 5GSH93501 is appropriate for designs requiring a lower actuator profile (6.40mm), higher actuation force (350gf), or extended temperature operation from -40°C to 160°C. The increased operating force and reduced height represent design improvements in the Multimec® 5 series.

Both parts share identical electrical ratings, mounting footprint, and environmental sealing specifications, ensuring functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the 5GSH93501 replace the 4ASH901 in existing designs?

A: Electrical and mechanical compatibility is confirmed for circuit-level functionality. However, the 2.00mm reduction in actuator height and 50gf increase in operating force must be evaluated against specific mechanical and ergonomic design constraints. PCB layout and enclosure clearances should be verified.

Q: What is the primary difference between these two parts?

A: The 5GSH93501 features a lower actuator height (6.40mm vs 8.40mm), higher operating force (350gf vs 300gf), and extended operating temperature range (-40°C ~ 160°C vs -30°C ~ 85°C). All electrical parameters and contact ratings remain identical.

Q: Are both parts available in the same packaging?

A: The 4ASH901 is supplied in standard packaging, while the 5GSH93501 is packaged in tubes. Packaging format should be confirmed with procurement requirements.

Q: Do both parts meet the same compliance standards?

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

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

A: The 5GSH93501 supports operation up to 160°C, compared to 85°C for the 4ASH901. For applications exceeding 85°C, the 5GSH93501 is the appropriate selection.
