Substitute Part Grouping Explanation

The 55505-00-02-C has one manufacturer-recommended substitute: the 55505-00-02-B. Substitution eligibility is determined by the following critical parameters:

• Sensor Type & Output: Both parts are Hall effect sensors with digital output
• Actuator Material Compatibility: Both detect ferrous metals and gear teeth
• Termination Configuration: Both feature wire leads with connector termination
• Electrical Specifications: Identical supply voltage range (4.75V ~ 25.2V) and frequency response (15 kHz)
• Environmental Ratings: Matching operating temperature range (-40°C ~ 125°C)
• Mechanical Form Factor: Both use flange mount packaging
• Regulatory Compliance: Both are ROHS3 compliant

The primary distinction between these parts is product status: the 55505-00-02-C is obsolete, while the 55505-00-02-B is active with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The 55505-00-02-B is the direct manufacturer-recommended substitute for the obsolete 55505-00-02-C. Both parts share identical electrical, mechanical, and environmental specifications, ensuring functional equivalence in applications requiring ferrous metal or gear tooth detection with digital output.

The 55505-00-02-B is the preferred selection for new designs and ongoing production due to its active product status and higher inventory availability. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, supporting deployment in standard industrial environments.

Frequently Asked Questions (FAQ)

Q: Can the 55505-00-02-B directly replace the 55505-00-02-C in existing applications?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including supply voltage range, frequency response, operating temperature, and flange mount configuration. No circuit modifications are required.

Q: What is the difference between these two part numbers?
