Littelfuse 59075-010 Magnetic Reed Switch Equivalent & Substitute Parts

Part Overview

The Littelfuse 59075-010 is an active SPST-NO magnetic reed switch with wire leads, housed in a cylinder threaded package. This component functions as a magnetically actuated switch suitable for applications requiring contact closure upon magnetic field detection. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to address inventory availability, packaging preferences, or specific operational parameter requirements while maintaining functional equivalence within the reed switch category.

Substitute Part Grouping Explanation

The Littelfuse 59075-1-U-03-A qualifies as a manufacturer-recommended substitute for the 59075-010 based on the following substitution criteria:

Functional Equivalence Parameters:

• Identical output type: SPST-NO (Single Pole Single Throw, Normally Open)
• Identical actuator material: Magnet
• Identical termination style: Wire Leads
• Identical package form: Cylinder, Threaded
• Identical series designation: 59075
• Identical category: Magnetic Sensors / Reed Switch

Operational Parameter Variance:

• Must Operate distance: 59075-010 operates at 10.00 mm; 59075-1-U-03-A operates at 19.00 mm
• Must Release distance: 59075-010 releases at 30.00 mm; 59075-1-U-03-A specification not provided

Compliance & Certification Alignment:

• Both parts maintain RoHS3 compliance
• Both parts carry MSL rating of 1 (Unlimited)
• Both parts hold active product status

The substitute part is suitable for applications where the increased must-operate distance (19.00 mm vs. 10.00 mm) is acceptable or beneficial for the intended magnetic field detection range.

Parameter Comparison

Engineering Selection Recommendations

Both the 59075-010 and 59075-1-U-03-A maintain active product status with full RoHS3 compliance and identical MSL ratings. Selection between these parts depends on the specific magnetic detection distance requirement for the application:

• 59075-010 is appropriate for applications requiring actuation at 10.00 mm magnetic field distance with release at 30.00 mm.
• 59075-1-U-03-A is appropriate for applications where a 19.00 mm actuation distance is acceptable or required, offering extended magnetic field detection range.

Both parts are manufactured by Littelfuse Inc. within the same 59075 series and share identical electrical output characteristics (SPST-NO), actuator type (Magnet), termination method (Wire Leads), and physical form factor (Cylinder, Threaded). The substitute part is available in bulk packaging, which may provide cost or supply chain advantages for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the 59075-1-U-03-A directly replace the 59075-010 in my application?

A: Direct replacement is possible only if your application can accommodate the increased must-operate distance of 19.00 mm compared to the original 10.00 mm specification. Both parts share identical output type (SPST-NO), package form, and wire lead termination. Verify that your magnetic field source and circuit design support the longer actuation distance before substitution.

Q: What is the primary difference between these two parts?

A: The primary difference is the must-operate distance: the 59075-010 actuates at 10.00 mm, while the 59075-1-U-03-A actuates at 19.00 mm. Both parts are SPST-NO magnetic reed switches with wire leads in a cylinder threaded package from the same manufacturer series.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance status, MSL rating of 1 (Unlimited), and active product status. There are no compliance or certification barriers to substitution.

Q: What does the packaging difference mean?

A: The 59075-010 packaging specification is not provided in the available data. The 59075-1-U-03-A is supplied in bulk packaging. Bulk packaging typically indicates loose component supply without individual packaging, which may affect handling, storage, and cost considerations for your procurement process.

Q: How do I determine which part is suitable for my circuit?

A: Evaluate the magnetic field distance in your application. If your magnet source is positioned at or closer than 10.00 mm from the switch, use the 59075-010. If your application allows or requires detection at distances up to 19.00 mm, the 59075-1-U-03-A is suitable. Both parts will function identically once actuated, as they share the same SPST-NO output characteristics.
