Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3500S-2-102 is determined by matching the following critical parameters:

• Resistance value: 1k Ohm
• Power rating: 2W
• Tolerance: ±3%
• Number of turns: 10
• Taper characteristic: Linear
• Resistive material: Wirewound
• Termination style: Solder Lug
• Mounting configuration: Panel Mount
• Actuator type: Slotted
• Temperature coefficient: ±50ppm/°C
• Mechanical dimensions: Bushing thread 3/8-32, body diameter 0.875" (22.23mm)

The 3500S-2-102L meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and regulatory compliance, not functional or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 3500S-2-102L is the direct functional equivalent of the 3500S-2-102. All electrical and mechanical parameters are identical. Selection between these parts should be based on the following factors:

Product Status: The 3500S-2-102 is obsolete. The 3500S-2-102L carries active product status, ensuring ongoing availability and manufacturer support.

Regulatory Compliance: The 3500S-2-102L is ROHS3 compliant, whereas the 3500S-2-102 is non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 3500S-2-102L is the appropriate selection.

REACH Compliance: The 3500S-2-102L is REACH affected, indicating it has been evaluated under REACH regulations. The original part is REACH unaffected. Applications requiring REACH-compliant components should specify the 3500S-2-102L.

Packaging: The 3500S-2-102L is supplied in bulk packaging, which may affect procurement workflows and inventory management compared to the original part specification.

Frequently Asked Questions (FAQ)

Q: Can the 3500S-2-102L be used as a direct replacement for the 3500S-2-102?

A: Yes. All functional, electrical, and mechanical parameters are identical. The 3500S-2-102L is a direct substitute with no circuit or mechanical redesign required.

Q: What is the primary reason to transition from 3500S-2-102 to 3500S-2-102L?
