Bourns 3541H-1-502 Potentiometer Equivalent & Substitute Parts

Part Overview

The Bourns 3541H-1-502 is a 5k Ohm, 2W linear panel mount potentiometer featuring Hybritron® resistive material with a 10-turn configuration and solder lug termination. This component is classified as obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

The primary reason for identifying substitute parts is the obsolete status of the original component, which restricts availability through standard distribution channels and may impact long-term supply chain reliability for maintenance and production applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3541H-1-502 is determined by strict equivalence across the following critical parameters:

• Resistance value: 5k Ohm
• Power rating: 2W
• Taper characteristic: Linear
• Number of turns: 10
• Termination style: Solder Lug
• Mounting configuration: Panel Mount
• Physical dimensions: Round body 0.875" diameter
• Bushing thread specification: 3/8-32

The substitute part 3541H-1-502L maintains identical electrical and mechanical specifications across all these parameters, differing only in product status (Active vs. Obsolete) and regulatory compliance certifications.

Parameter Comparison

• Identical electrical performance and mechanical fit within existing circuit designs and mechanical assemblies
• Tray packaging suitable for automated assembly and production environments

The 3541H-1-502L maintains full backward compatibility with applications originally specified for the 3541H-1-502, with no circuit redesign or mechanical modification required.

Frequently Asked Questions (FAQ)

Q: Can the 3541H-1-502L be used as a direct replacement for the 3541H-1-502?

A: Yes. The 3541H-1-502L is electrically and mechanically identical to the 3541H-1-502 across all functional parameters, including resistance value, power rating, taper, number of turns, termination style, and physical dimensions. No circuit or mechanical modifications are required.

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

A: The 3541H-1-502 is obsolete, while the 3541H-1-502L is active. Additionally, the 3541H-1-502L meets ROHS3 compliance and REACH requirements, whereas the original part does not. Packaging differs, with the substitute supplied in Tray format.

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts share identical electrical specifications: 5k Ohm resistance, ±10% tolerance, 2W power rating, ±100ppm/°C temperature coefficient, and 10-turn linear taper configuration.

Q: Will the 3541H-1-502L fit in existing mechanical assemblies designed for the 3541H-1-502?

A: Yes. Physical dimensions, bushing thread specification (3/8-32), actuator dimensions, and mounting configuration are identical between both parts.

Q: What regulatory advantages does the 3541H-1-502L provide?

A: The 3541H-1-502L is ROHS3 compliant and REACH affected, meeting current environmental regulations. The original 3541H-1-502 is RoHS non-compliant and REACH unaffected, making the substitute more suitable for applications subject to modern regulatory requirements.

Q: Is the packaging difference significant for my application?

A: Packaging format (Tray for the 3541H-1-502L versus unspecified for the 3541H-1-502) affects handling, storage, and automated assembly compatibility. Tray packaging is standard for production environments and automated pick-and-place systems.
