Littelfuse 59010-1-S-02-B Magnetic Reed Switch Equivalent & Substitute Parts

Part Overview

The Littelfuse 59010-1-S-02-B is a magnetic reed switch sensor with SPST-NO (Single Pole Single Throw - Normally Open) output configuration, designed for magnetic actuation applications. This component features wire lead termination and operates across an industrial temperature range of -40°C to 85°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional and electrical compatibility for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 59010-1-S-02-B is determined by strict equivalence across the following critical parameters:

• Functional Output: SPST-NO configuration (identical switching behavior)
• Magnetic Actuation: Magnet-actuated reed switch technology
• Operational Distance: 6.00mm must-operate specification
• Temperature Range: -40°C to 85°C operating envelope
• Regulatory Compliance: ROHS3 compliance and EAR99 classification
• Series Compatibility: Littelfuse 59010 series platform

The identified substitutes maintain full functional equivalence while differing only in product status (active vs. obsolete) and termination connector configuration. Both substitute parts are manufactured by Littelfuse Inc. and are currently in active production status with confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

59010-1-S-02-A is the direct functional equivalent for applications requiring standard wire lead termination. This part maintains identical electrical and mechanical specifications while offering active product status and higher inventory availability. Selection of this substitute eliminates obsolescence risk and ensures long-term supply chain continuity.

59010-1-S-02-F provides equivalent magnetic reed switch functionality with integrated connector termination on the wire leads. This variant is suitable for applications where connector-based integration is preferred or required. The integrated connector does not alter the core switching characteristics or operational parameters.

Both substitutes carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. Selection between 59010-1-S-02-A and 59010-1-S-02-F depends solely on termination interface requirements within the target application.

Frequently Asked Questions (FAQ)

Q: Can 59010-1-S-02-A directly replace 59010-1-S-02-B in existing designs?

A: Yes. Both parts are functionally identical across all critical parameters: SPST-NO output, 6.00mm magnetic actuation distance, -40°C to 85°C operating range, and probe package configuration. The primary difference is product status (active vs. obsolete) and packaging format (bulk vs. original).

Q: What is the difference between 59010-1-S-02-A and 59010-1-S-02-F?

A: The termination style differs. 59010-1-S-02-A features standard wire leads, while 59010-1-S-02-F includes integrated connector termination on the wire leads. Both maintain identical switching specifications and operating parameters.

Q: Are there electrical performance differences between these substitutes?

A: No. All three parts share identical electrical characteristics: SPST-NO switching configuration, 6.00mm must-operate distance, and -40°C to 85°C temperature range. Differences are limited to product lifecycle status and physical termination interface.

Q: Which substitute should be selected for new designs?

A: Either 59010-1-S-02-A or 59010-1-S-02-F is appropriate for new designs, as both are active products with confirmed inventory. Selection depends on whether standard wire leads (59010-1-S-02-A) or connector-integrated termination (59010-1-S-02-F) aligns with the application's interface requirements.

Q: Do all three parts meet current regulatory compliance?

A: The main part (59010-1-S-02-B) and both substitutes are ROHS3 compliant. The substitutes additionally carry REACH Unaffected status, confirming compliance with current environmental regulations.
