Littelfuse 59150-2-T-02-F Equivalent & Substitute Parts

Part Overview

The Littelfuse 59150-2-T-02-F is a magnetic reed switch with SPST-NO (Single Pole Single Throw - Normally Open) output configuration, designed for flange mount applications with wire leads termination. This component operates across a temperature range of -20°C to 105°C and features a must-operate specification of 17 ~ 23AT. The part is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure ongoing component availability for new production and field replacements.

Substitute Part Grouping Explanation

Substitution of the Littelfuse 59150-2-T-02-F is determined by the following critical parameters:

• Output Type: SPST-NO configuration is mandatory for functional equivalence
• Actuator Material: Magnet-actuated operation must be maintained
• Package / Case: Flange mount form factor ensures mechanical compatibility
• RoHS Compliance: ROHS3 compliance aligns with regulatory requirements
• Operating Temperature Range: The substitute must support the application's thermal environment
• Product Status: Active status ensures ongoing availability and supply chain continuity

The Comus International PSA 240/30 - BLUE satisfies these core substitution criteria through matching output type, actuator material, package configuration, and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The Comus International PSA 240/30 - BLUE is the designated manufacturer-recommended substitute for the obsolete Littelfuse 59150-2-T-02-F. Both components share identical output type (SPST-NO), actuator material (magnet), package configuration (flange mount), and regulatory compliance (ROHS3). The substitute maintains active product status, ensuring reliable supply chain availability.

The primary design consideration is the operating temperature range differential: the Littelfuse component operates to 105°C, while the Comus substitute operates to 85°C. Applications requiring operation above 85°C require thermal environment verification prior to substitution.

Termination style differs between the two components: the original uses wire leads while the substitute uses cable leads. This difference may require mechanical interface adaptation depending on the application's connection methodology.

Frequently Asked Questions (FAQ)

Q: Can the Comus PSA 240/30 - BLUE directly replace the Littelfuse 59150-2-T-02-F?

A: The Comus component is the manufacturer-recommended substitute and shares critical functional parameters including SPST-NO output, magnet actuation, flange mount packaging, and ROHS3 compliance. Termination style differs (cable leads versus wire leads), requiring connection method evaluation. Operating temperature range differs (85°C maximum versus 105°C maximum).

Q: What is the significance of the termination style difference?

A: The original Littelfuse component features wire leads, while the Comus substitute features cable leads. This affects the physical connection interface. Applications must accommodate the cable lead configuration or employ appropriate adapters.

Q: Are both components RoHS compliant?

A: Yes. Both the Littelfuse 59150-2-T-02-F and Comus PSA 240/30 - BLUE are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: What is the operating temperature consideration for substitution?

A: The Littelfuse component operates from -20°C to 105°C, while the Comus substitute operates from -20°C to 85°C. Applications requiring sustained operation above 85°C must evaluate thermal requirements before substitution.

Q: Why is the original part listed as obsolete?

A: Obsolete status indicates the Littelfuse 59150-2-T-02-F is no longer in active production. The Comus PSA 240/30 - BLUE maintains active status, providing ongoing availability for new designs and field replacements.
