FS03 Force Sensor Equivalent & Substitute Parts

Part Overview

The FS03 is a surface-mount resistive force sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for pushbutton applications with a 3 lbs (1.36 kgf) operating force rating. The sensor delivers 1V output at 5V supply voltage and operates across a compensated temperature range of 5°C to 50°C.

The FS03 carries an Obsolete product status. Identifying equivalent and substitute components is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FS03 is determined by the following critical parameters:

Force Rating: Operating force of 1.36 kgf (3 lbs) must be maintained to ensure functional compatibility with the original application.

Sensor Type: Resistive sensor technology must be preserved to maintain signal conditioning and output characteristics.

Output Specification: 1V output at 5V supply voltage establishes the signal level and power requirements.

Actuator Configuration: Round pushbutton actuator with 12.2 mm size defines the mechanical interface and form factor.

Temperature Compensation: Compensated temperature range of 5°C to 50°C must be supported to maintain accuracy within the specified operating window.

Compliance Requirements: RoHS compliance and MSL rating of 1 (Unlimited) must be retained for regulatory and manufacturing process compatibility.

The FSAGPNXX003LCAC5 qualifies as a direct substitute based on matching force rating, sensor type, output specification, actuator configuration, temperature compensation range, and compliance certifications. The transition from FS series to FSA series represents an evolution within the same product family from the same manufacturer.

Engineering Selection Recommendations

Primary Selection: FSAGPNXX003LCAC5 is the qualified substitute for FS03 applications.

Justification: The FSAGPNXX003LCAC5 maintains electrical and mechanical parameter equivalence with the FS03 across all critical specifications: force rating, sensor type, output voltage, supply voltage, actuator configuration, and temperature compensation range. Both components are manufactured by Honeywell Sensing and Productivity Solutions and carry RoHS compliance certification with MSL rating of 1 (Unlimited).

Product Status Consideration: The FS03 is classified as Obsolete, while FSAGPNXX003LCAC5 maintains Active product status. This transition ensures continued availability, manufacturing support, and supply chain reliability for new production and replacement applications.

Packaging Transition: The substitute part is supplied in Tube packaging, which may require adjustment to receiving and handling procedures if the original FS03 packaging format differs.

Accuracy Specification: The FSAGPNXX003LCAC5 specifies ±3% accuracy. Applications requiring accuracy verification should confirm this specification meets system-level performance requirements.

Frequently Asked Questions (FAQ)

Q: Can FSAGPNXX003LCAC5 directly replace FS03 in existing designs?

A: Yes. The FSAGPNXX003LCAC5 maintains electrical and mechanical equivalence across all specified parameters: 1.36 kgf (3 lbs) operating force, 1V output at 5V supply, resistive sensor type, round 12.2 mm pushbutton actuator, and 5°C to 50°C compensated temperature range. No circuit or mechanical redesign is required.

Q: What is the difference between FS03 and FSAGPNXX003LCAC5?

A: Both sensors are functionally equivalent. The primary differences are: (1) FS03 is Obsolete; FSAGPNXX003LCAC5 is Active; (2) FSAGPNXX003LCAC5 specifies ±3% accuracy; (3) FSAGPNXX003LCAC5 is supplied in Tube packaging; (4) FSAGPNXX003LCAC5 uses the FSA series designation, representing a product line evolution within Honeywell's force sensor portfolio.

Q: Are there any compliance or certification differences?

A: No. Both components are RoHS Compliant with MSL rating of 1 (Unlimited). Both carry ECCN classification EAR99. Regulatory and manufacturing process compatibility is maintained.

Q: Does packaging format affect component selection?

A: Packaging format does not affect electrical or mechanical performance. FSAGPNXX003LCAC5 is supplied in Tube packaging. Organizations should verify that receiving, storage, and handling procedures accommodate this packaging format.

Q: Is the ±3% accuracy specification of FSAGPNXX003LCAC5 a concern for FS03 replacement?

A: The FS03 does not specify an accuracy value in available documentation. The ±3% accuracy of FSAGPNXX003LCAC5 represents a defined performance characteristic. Applications should confirm that ±3% accuracy meets system-level requirements. If accuracy specifications for the original FS03 are available, direct comparison should be performed.

Q: Can FSAGPNXX003LCAC5 be used in applications with operating temperatures outside 5°C to 50°C?

A: The compensated temperature range is 5°C to 50°C for both components. The FS03 specifies an operating temperature range of 0°C to 70°C. Applications requiring operation outside the compensated range should verify that sensor performance remains acceptable, as temperature compensation is not active in those regions.
