MAX4554ESE Force Sense Switch IC Equivalent & Substitute Parts
Part Overview
The MAX4554ESE is a Force Sense Switch IC manufactured by Analog Devices Inc./Maxim Integrated, designed for interface applications requiring 2-channel force sense switching functionality. This component features a 3PST (3-Pole Single-Throw) switch circuit in a 16-SOIC surface mount package with an on-state resistance maximum of 6Ω.
The MAX4554ESE is classified as obsolete, which necessitates identification of equivalent substitute components for new designs and ongoing production requirements. Active alternatives with identical electrical and mechanical specifications are available to ensure design continuity and supply chain reliability.

Engineering Selection Recommendations
The MAX4554ESE+ is the direct substitute for MAX4554ESE applications. Selection should be based on the following criteria:
Product Status & Availability: The MAX4554ESE is obsolete with no ongoing manufacturing. The MAX4554ESE+ is active and maintains full inventory availability, making it the appropriate choice for new designs and production continuity.
Regulatory Compliance: The MAX4554ESE+ achieves ROHS3 compliance, whereas the original MAX4554ESE is RoHS non-compliant. For applications subject to RoHS regulations, the MAX4554ESE+ is the required selection.
Electrical & Mechanical Equivalence: Both parts maintain identical electrical specifications across supply voltage ranges, on-state resistance, operating temperature, and switch circuit topology. Both utilize the same 16-SOIC package footprint, ensuring direct PCB compatibility without layout modifications.
Packaging Consideration: The MAX4554ESE+ is supplied in tube packaging, which may differ from the original part's packaging format. Verify compatibility with existing assembly and handling procedures.
Frequently Asked Questions (FAQ)
Q: Can MAX4554ESE+ be used as a direct replacement for MAX4554ESE in existing designs?
A: Yes. The MAX4554ESE+ provides complete electrical and mechanical equivalence. Both parts feature identical 3PST switch circuits, 2-channel configuration, 6Ω on-state resistance, supply voltage ranges, operating temperature specifications, and 16-SOIC package geometry. No circuit modifications or PCB redesign is required.
Q: What is the primary reason for substitution?
A: The MAX4554ESE is obsolete and no longer manufactured. The MAX4554ESE+ is the active equivalent from the same manufacturer, ensuring continued supply and design support.
Q: Are there compliance differences between the two parts?
A: Yes. The MAX4554ESE+ is ROHS3 compliant, while the MAX4554ESE is RoHS non-compliant. For applications requiring RoHS compliance, the MAX4554ESE+ is mandatory.
Q: Will the MAX4554ESE+ fit the same PCB footprint?
A: Yes. Both parts use the 16-SOIC package with identical dimensions (0.154" width, 3.90mm). No PCB modifications are necessary for footprint compatibility.
Q: Are there any electrical performance differences?
A: No. Both parts maintain identical on-state resistance (6Ω maximum), supply voltage specifications (9V ~ 40V single, ±4.5V ~ 20V dual), and operating temperature range (-40°C ~ 85°C).
Q: What packaging formats are available?
A: The MAX4554ESE+ is supplied in tube packaging. Verify compatibility with your assembly process and handling requirements.
