Key Parameters

Substitute Part Grouping Explanation

The 3590S-1-202L qualifies as a direct substitute based on identical electrical and mechanical specifications. Substitution criteria are determined by the following parameters:

• Resistance value: 2k Ohm (exact match required)
• Power rating: 2W (exact match required)
• Taper characteristic: Linear (exact match required)
• Number of turns: 10 (exact match required)
• Resistive material: Wirewound (exact match required)
• Termination style: Solder Lug (exact match required)
• Mounting configuration: Panel Mount (exact match required)
• Tolerance: ±5% (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Physical dimensions: Round body 0.875" diameter, 3/8-32 bushing thread (exact match required)

The 3590S-1-202L maintains full compatibility across all specified electrical and mechanical parameters, enabling direct substitution in existing designs and applications.

Parameter Comparison

Engineering Selection Recommendations

The 3590S-1-202L is the appropriate selection for applications requiring the 2k Ohm, 2W wirewound potentiometer specification. The substitute part maintains complete electrical and mechanical compatibility while offering the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance satisfies current regulatory requirements for new designs and manufacturing
• REACH affected status indicates compliance with chemical substance regulations

The obsolete status of the 3590S-1-202 necessitates transition to the 3590S-1-202L for all new procurement and design implementations.

Frequently Asked Questions (FAQ)

Q: Can the 3590S-1-202L be used as a direct replacement for the 3590S-1-202?

A: Yes. The 3590S-1-202L provides complete electrical and mechanical compatibility. All specified parameters including resistance, power rating, taper, number of turns, termination style, and physical dimensions are identical.

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

A: The primary differences are product status and compliance certifications. The 3590S-1-202 is obsolete and RoHS non-compliant, while the 3590S-1-202L is an active product with ROHS3 compliance and REACH affected status.

Q: Are there packaging differences between these parts?

A: The 3590S-1-202L is supplied in bulk packaging, whereas the main part number does not specify a packaging designation. This does not affect electrical or mechanical performance.

Q: Will the 3590S-1-202L work in existing circuit designs using the 3590S-1-202?

A: Yes. Identical electrical specifications and physical dimensions ensure full compatibility in existing designs without circuit modifications or mechanical redesign.

Q: What is the significance of the ROHS3 compliance on the 3590S-1-202L?

A: ROHS3 compliance indicates the part meets current Restriction of Hazardous Substances regulations, making it suitable for applications subject to environmental and regulatory compliance requirements.
