Key Parameters

Substitute Part Grouping Explanation

The Bourns 3590S-2-102L qualifies as a direct substitute based on the following criteria:

All electrical parameters are identical: 1kΩ resistance, 2W power rating, ±5% tolerance, 10-turn configuration, linear taper, and ±50ppm/°C temperature coefficient.

All mechanical parameters are identical: wirewound resistive material, solder lug termination, panel mount configuration, 3/8-32 bushing thread, 0.875" round body diameter, 0.812" slotted actuator length, and 0.2497" actuator diameter.

The substitute part maintains the same series designation (3590) and base product number (3590S), confirming design compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 3590S-2-102L is the appropriate selection for new designs and component replacement applications. The obsolete status of the 3590S-2-102 creates supply chain risk and limits procurement options. The substitute part is currently in active production with 15,280 units in stock, compared to 1,153 units of the obsolete variant.

The 3590S-2-102L achieves ROHS3 compliance, meeting current environmental and regulatory requirements for electronic components. The REACH Affected status of the substitute part indicates compliance with European chemical safety regulations, whereas the original part's REACH Unaffected status reflects its obsolete classification.

Both parts carry identical ECCN (EAR99) and HTSUS (8533.31.0000) classifications, confirming equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 3590S-2-102L be used as a direct replacement for the 3590S-2-102?

A: Yes. All electrical parameters (resistance, power rating, tolerance, temperature coefficient) and mechanical parameters (mounting, termination, actuator dimensions) are identical. The parts are mechanically and electrically interchangeable.

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

A: The primary difference is product status and regulatory compliance. The 3590S-2-102 is obsolete and RoHS non-compliant. The 3590S-2-102L is active production and ROHS3 compliant. The "L" suffix in the part number indicates the updated variant.

Q: Does packaging differ between these parts?

A: The 3590S-2-102 is supplied in standard packaging, while the 3590S-2-102L is supplied in bulk packaging. Both are suitable for solder lug termination and panel mount installation.

Q: Are there any performance differences?

A: No. Both parts deliver identical performance across all specified electrical and mechanical parameters, including resistance tolerance, power dissipation, temperature stability, and adjustment range.

Q: Which part should be specified for new designs?

A: The 3590S-2-102L should be specified for all new designs. It offers superior availability, active production status, and current regulatory compliance.
