Littelfuse 59150-2-V-02-F Magnetic Reed Switch Equivalent & Substitute Parts

Part Overview

The Littelfuse 59150-2-V-02-F is an active SPST-NO magnetic reed switch designed for flange mount applications with wire leads termination. This component functions as a normally-open contact switch actuated by magnetic field presence, commonly used in proximity sensing and control circuits. The part is currently in active production status with 1,030 units available in inventory. Equivalent parts may be required due to supply chain constraints, design standardization across manufacturing facilities, or specific application requirements where alternative termination styles or operating temperature ranges are acceptable.

Substitute Part Grouping Explanation

Substitution eligibility for the Littelfuse 59150-2-V-02-F is determined by the following critical parameters:

• Switch Type & Output Configuration: Must be SPST-NO reed switch with magnetic actuation
• Package Form Factor: Must be flange mount to ensure mechanical compatibility with existing mounting interfaces
• Actuator Mechanism: Must use magnet-based actuation
• Operating Temperature Range: Acceptable range must encompass or overlap the primary part's -20°C to 105°C specification
• Regulatory Compliance: Must maintain ROHS3 compliance status for equivalent environmental standards
• Electrical Characteristics: Must operate at the specified 9.00 mm actuation distance

The Comus International PSA 240/30 - BLUE meets these substitution criteria as a SPST-NO magnetic reed switch with flange mount configuration and magnet actuation. Termination style differs (cable leads versus wire leads) and operating temperature maximum is reduced to 85°C, representing acceptable trade-offs for applications not requiring the full upper temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both the Littelfuse 59150-2-V-02-F and Comus International PSA 240/30 - BLUE maintain active production status and ROHS3 compliance, ensuring regulatory alignment for current manufacturing standards. Selection between these parts should be based on application-specific thermal requirements: the Littelfuse part supports operation to 105°C, while the Comus part is rated to 85°C maximum. Termination style differences (wire leads versus cable leads) require mechanical interface verification with the intended mounting and connection infrastructure. Both components share identical switch topology (SPST-NO), actuation mechanism (magnet), and package form factor (flange mount), establishing functional equivalence for standard proximity sensing applications within the overlapping temperature range of -20°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can the PSA 240/30 - BLUE directly replace the 59150-2-V-02-F in all applications?

A: Direct replacement is valid for applications operating within -20°C to 85°C. Applications requiring sustained operation above 85°C must use the Littelfuse part. Termination style differences (cable leads versus wire leads) require verification of connector compatibility with existing circuit board or harness interfaces.

Q: What are the critical substitution criteria for these reed switches?

A: Substitution is valid when the replacement part maintains SPST-NO output configuration, magnetic actuation, flange mount package, and operating temperature range compatibility. Both parts meet these criteria within their respective thermal specifications.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. The Comus part includes REACH Unaffected status. No compliance barriers exist for substitution in regulated applications.

Q: How does the termination style difference affect circuit integration?

A: The Littelfuse part uses wire leads for direct soldering or crimping, while the Comus part uses cable leads for pre-assembled harness connections. Circuit board layout and connector specifications must accommodate the selected termination style.

Q: What is the significance of the 9.00 mm must-operate specification?

A: This parameter defines the magnetic actuation distance at which the switch contacts close. Both parts function as magnetic reed switches with this actuation characteristic, ensuring consistent switching behavior in proximity sensing applications.
