Parameter Comparison

Engineering Selection Recommendations

Both the 4ATH98222 and 5GTH9358222 are active production parts with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on the following criteria:

4ATH98222 (Multimec® 4 Series): Select when the original design specification calls for an 8.40mm actuator height and 300gf operating force. This part maintains the exact mechanical profile of the original design.

5GTH9358222 (Multimec® 5 Series): Select when design requirements allow for a reduced actuator height of 6.40mm, increased operating force of 350gf, or extended operating temperature range (-40°C ~ 160°C). The Multimec® 5 series represents a newer generation with enhanced thermal performance.

Both parts share identical electrical ratings, circuit configuration, mounting type, and ingress protection rating. The decision between them depends on mechanical envelope constraints and thermal operating requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 5GTH9358222 be used as a direct replacement for the 4ATH98222 in existing designs?

A: The 5GTH9358222 is electrically and functionally compatible with the 4ATH98222. However, the 2.00mm reduction in actuator height and 50gf increase in operating force must be evaluated against the specific mechanical and ergonomic requirements of the application. PCB layout and enclosure clearance should be verified before substitution.

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

A: The primary differences are: 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 generation (Multimec® 4 vs. Multimec® 5). All other electrical and mechanical parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the 4ATH98222 and 5GTH9358222 are ROHS3 compliant with MSL rating 1 (Unlimited moisture sensitivity level).

Q: Does the packaging format affect compatibility?

A: Packaging format (tube for the 5GTH9358222) affects handling, storage, and procurement logistics but does not affect electrical or mechanical compatibility. Verify packaging requirements for your assembly process.

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

A: The 5GTH9358222 is rated for operating temperatures up to 160°C, compared to 85°C for the 4ATH98222. For applications requiring extended thermal performance, the 5GTH9358222 is the appropriate selection.

Q: Are the illumination specifications identical?

A: Yes, both parts feature identical LED illumination (green/red) with nominal voltage of 2.0 and 2.2 VDC.
