Substitute Part Grouping Explanation

The 55100-2M-04-D has one manufacturer-recommended substitute: the 55100-2M-05-A. Substitution eligibility is determined by the following critical parameters:

• Hall Effect Switch type with current output
• South Pole magnet actuator material
• Identical voltage supply range (3V ~ 24V)
• Identical frequency specification (10 kHz)
• Identical must-operate distance (14.60mm)
• Identical operating temperature range (-40°C ~ 100°C)
• Same series designation (55100)
• Equivalent RoHS3 compliance and MSL rating

The primary distinction between these parts is the termination style and product status. The 55100-2M-04-D features wire leads with connector termination and is obsolete. The 55100-2M-05-A provides wire leads termination without connector integration and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The 55100-2M-05-A is the direct manufacturer-recommended substitute for the obsolete 55100-2M-04-D. Both components share identical electrical and mechanical specifications across all critical parameters: Hall Effect switching functionality, current output, South Pole magnet actuation, voltage range, frequency response, operating distance, and temperature range.

The primary design consideration is termination style. The 55100-2M-04-D integrates a connector with wire leads, while the 55100-2M-05-A provides wire leads only. System integration must account for this termination difference during component selection and circuit board layout.

The 55100-2M-05-A maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity. Both components meet ROHS3 compliance requirements and carry identical moisture sensitivity ratings, supporting equivalent environmental performance in production and field deployment.

Frequently Asked Questions (FAQ)

Q: Can the 55100-2M-05-A directly replace the 55100-2M-04-D in existing designs?

A: Electrical and magnetic specifications are identical. Termination style differs: the 55100-2M-04-D includes connector integration, while the 55100-2M-05-A provides wire leads only. Circuit board layout and connector interface requirements must be evaluated during integration.

Q: What is the significance of the obsolete status for the 55100-2M-04-D?

A: Obsolete status indicates discontinued manufacturing. The 55100-2M-05-A is the active equivalent, ensuring ongoing availability and manufacturer support for new designs and system maintenance.

Q: Are the operating parameters identical between these two parts?

A: Yes. Voltage supply range (3V ~ 24V), frequency (10 kHz), must-operate distance (14.60mm), and operating temperature range (-40°C ~ 100°C) are identical. Both components use South Pole magnet actuation and current output.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 55100-2M-04-D and 55100-2M-05-A are ROHS3 compliant with MSL rating 1 (Unlimited), supporting equivalent environmental and regulatory requirements.

Q: What packaging differences exist between these parts?

A: The 55100-2M-04-D is supplied in module packaging without specified box designation. The 55100-2M-05-A is supplied in box packaging. Both maintain identical component specifications and performance characteristics.
