Parameter Comparison

Engineering Selection Recommendations

The 3296W-1-100LF is a direct electrical and mechanical equivalent to the 3296W-1-100. Selection between these parts should be based on compliance requirements and supply chain considerations:

• For applications requiring RoHS3 compliance, the 3296W-1-100LF is the appropriate selection.
• For applications with no RoHS compliance requirement, either part is functionally equivalent.
• The 3296W-1-100LF offers significantly higher inventory availability (30,300 units versus 4,400 units), supporting extended production runs and supply chain continuity.
• Both parts maintain identical electrical performance, mechanical fit, and thermal characteristics within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 3296W-1-100LF be used as a direct replacement for the 3296W-1-100?

A: Yes. The 3296W-1-100LF is electrically and mechanically identical to the 3296W-1-100. All functional parameters, including resistance, power rating, tolerance, temperature coefficient, adjustment mechanism, and physical dimensions, are equivalent. The primary difference is RoHS3 compliance status.

Q: What does the "LF" suffix in the part number 3296W-1-100LF indicate?

A: The "LF" suffix indicates lead-free construction, which is associated with RoHS3 compliance. This designation reflects the manufacturing process and material composition used to meet regulatory requirements.

Q: Are there any performance differences between the 3296W-1-100 and 3296W-1-100LF?

A: No. Both parts deliver identical electrical performance across all specified parameters: 10 Ohm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, and 25-turn adjustment mechanism. Mechanical fit and thermal behavior are also equivalent.

Q: Which part should be selected for new designs?

A: For new designs, the 3296W-1-100LF is the recommended selection due to RoHS3 compliance and superior inventory availability. This part supports regulatory alignment and supply chain stability.

Q: Are both parts available in the same packaging format?

A: Yes. Both the 3296W-1-100 and 3296W-1-100LF are supplied in tube packaging, ensuring consistent handling and storage requirements.

Q: What is the impact of the temperature coefficient on circuit performance?

A: The ±100ppm/°C temperature coefficient indicates the resistance change per degree Celsius. For the 10 Ohm base resistance, this results in a maximum resistance variation of ±0.001 Ohm per degree Celsius. This specification applies identically to both parts.
