Substitute Part Grouping Explanation

The 55100-2M-05-A is identified as the manufacturer-recommended substitute for the 55100-2M-05-D. Substitution eligibility is determined by matching the following critical electrical and mechanical parameters:

• Hall Effect Switch type with current output
• South Pole magnet actuator material
• 10 kHz frequency specification
• 3V to 24V supply voltage range
• 14.60mm must operate distance
• -40°C to 100°C operating temperature range
• Module package configuration
• ROHS3 compliance and MSL Level 1 rating

The primary distinction between these parts is the termination style and product status. The 55100-2M-05-D features wire leads with connector termination and is obsolete, while the 55100-2M-05-A uses wire leads termination and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The 55100-2M-05-A is the appropriate selection for applications currently specified with the 55100-2M-05-D. Both components maintain identical electrical performance characteristics, frequency response, and environmental operating ranges. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and MSL Level 1 rating, satisfying regulatory and manufacturing requirements.

The termination style difference—wire leads with connector versus wire leads alone—requires evaluation within the specific application context. Design modifications to accommodate the termination style change may be necessary depending on the existing interconnection scheme.

Frequently Asked Questions (FAQ)

Q: Can the 55100-2M-05-A directly replace the 55100-2M-05-D in existing designs?

A: Electrical and functional compatibility is confirmed across all specified parameters. The termination style difference requires assessment of the application's interconnection requirements. Wire leads with connector termination differs from wire leads termination, necessitating potential connector or wiring modifications.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status indicates ongoing manufacturer support, continued production, and assured long-term availability. This eliminates supply risk associated with obsolete components and provides access to current manufacturing batches.

Q: Are both parts compliant with the same regulatory standards?

A: Both the 55100-2M-05-D and 55100-2M-05-A maintain ROHS3 compliance and MSL Level 1 rating. Regulatory compliance is equivalent across both components.

Q: What packaging differences exist between these parts?

A: The 55100-2M-05-D is supplied in standard packaging, while the 55100-2M-05-A is supplied in box packaging. Both maintain Module package configuration for the component itself.

Q: Are the operating temperature and voltage ranges identical?

A: Both parts operate across -40°C to 100°C temperature range and support 3V to 24V supply voltage. Operating specifications are equivalent.
