Bourns 3590S-2-103 Wirewound Potentiometer Equivalent & Substitute Parts

Part Overview

The Bourns 3590S-2-103 is a 10k Ohm, 2W wirewound linear potentiometer designed for panel mount applications with a 10-turn adjustment mechanism. This component is classified as obsolete, which necessitates identification of active equivalent parts to maintain supply chain continuity and support ongoing production or repair requirements. The substitute part maintains identical electrical and mechanical specifications while offering improved availability and regulatory compliance.

Substitute Part Grouping Explanation

The 3590S-2-103L qualifies as a direct substitute based on matching all critical electrical and mechanical parameters: identical resistance value (10k Ohm), power rating (2W), taper characteristic (Linear), number of turns (10), resistive material (Wirewound), termination style (Solder Lug), and mounting configuration (Panel Mount). The tolerance (±5%), temperature coefficient (±50ppm/°C), and physical dimensions including bushing thread (3/8-32) and body size (0.875" Dia) are identical across both parts. The primary distinction is product status and regulatory compliance: the original part is obsolete, while the substitute is active in production with improved RoHS and REACH compliance.

Parameter Comparison

Engineering Selection Recommendations

The 3590S-2-103L is the appropriate selection for new designs and component replenishment. The substitute part maintains complete electrical and mechanical compatibility with the original 3590S-2-103 while offering the advantage of active production status and ROHS3 compliance. For applications subject to RoHS or REACH regulatory requirements, the 3590S-2-103L is the mandated choice. The original part's obsolete status and non-compliant regulatory posture make it unsuitable for procurement in current supply chains.

Frequently Asked Questions (FAQ)

Q: Can the 3590S-2-103L be used as a direct replacement for the 3590S-2-103?

A: Yes. All electrical parameters (resistance, power rating, tolerance, temperature coefficient, taper) and mechanical specifications (mounting type, bushing thread, body dimensions, actuator geometry, termination style) are identical. The parts are functionally interchangeable.

Q: What is the difference between these two part numbers?

A: The primary differences are product lifecycle status and regulatory compliance. The 3590S-2-103 is obsolete and RoHS non-compliant, while the 3590S-2-103L is active in production and ROHS3 compliant. The "L" suffix designation indicates the updated compliance variant.

Q: Are there packaging differences between the two parts?

A: The original part is specified with "-" packaging notation, while the substitute is supplied in Bulk packaging. This reflects standard industry practice for active production components and does not affect functional compatibility.

Q: Which part should be specified for new circuit board designs?

A: The 3590S-2-103L should be specified for all new designs. The original part's obsolete status makes it unavailable for new procurement, and the substitute's active status ensures long-term supply chain support.

Q: Is the 3590S-2-103L suitable for applications requiring RoHS compliance?

A: Yes. The 3590S-2-103L carries ROHS3 compliance certification, making it suitable for applications with RoHS regulatory requirements. The original part does not meet this requirement.
