Key Parameters

Substitute Part Grouping Explanation

The 55100-2M-01-A qualifies for direct substitution with the 55100-2M-02-A based on the following critical parameters:

• Identical manufacturer (Littelfuse)
• Same series designation (55100)
• Matching sensor type (Hall Effect Switch)
• Identical output type (Current)
• Identical termination style (Wire Leads)
• Identical actuator material (Magnet, South Pole)
• Matching voltage supply range (3V ~ 24V)
• Matching operating temperature range (-40°C ~ 100°C)
• Identical frequency specification (10 kHz)
• Identical must operate distance (14.60mm)
• Identical package classification (Module)

The primary distinction is product status: the 55100-2M-01-A is obsolete, while the 55100-2M-02-A is active production. The 55100-2M-02-A represents the current manufacturing equivalent with full availability and ongoing support.

Parameter Comparison

Engineering Selection Recommendations

The 55100-2M-02-A is the direct active equivalent for the obsolete 55100-2M-01-A. Both components maintain identical electrical and mechanical specifications across all critical parameters. The 55100-2M-02-A carries active product status with current manufacturing support and full ROHS3 compliance certification. Selection of the 55100-2M-02-A ensures continuity of supply and compliance with current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 55100-2M-02-A directly replace the 55100-2M-01-A in existing designs?

A: Yes. All electrical parameters, mechanical dimensions, and functional specifications are identical. No circuit modifications or design changes are required.

Q: What is the primary reason for substitution?

A: The 55100-2M-01-A is classified as obsolete. The 55100-2M-02-A is the active production equivalent with ongoing availability and manufacturer support.

Q: Are there packaging differences between these parts?

A: Both components use Module packaging. The 55100-2M-01-A specifies no packaging detail, while the 55100-2M-02-A is supplied in Box packaging. This represents a logistics difference only and does not affect functional compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 55100-2M-01-A and 55100-2M-02-A are ROHS3 compliant with identical moisture sensitivity levels (MSL 1, Unlimited).

Q: What is the operating distance specification?

A: Both parts require a 14.60mm must operate distance for reliable magnetic field detection with south pole magnet actuation.

Q: Are there any supply chain considerations?

A: The 55100-2M-02-A has significantly higher inventory availability (4833 Pcs) compared to the obsolete 55100-2M-01-A (1083 Pcs). For new production and long-term supply assurance, the 55100-2M-02-A is the recommended selection.
