Substitute Part Grouping Explanation

The 3329W-1-502LF is a direct substitute for the 3329W-1-502. Substitution is valid based on the following criteria:

• Identical resistance value: 5 kOhms
• Identical power rating: 0.5W (1/2W)
• Identical tolerance: ±10%
• Identical temperature coefficient: ±100ppm/°C
• Identical number of turns: 1
• Identical adjustment type: Side Adjustment
• Identical resistive material: Cermet
• Identical mounting type: Through Hole
• Identical termination style: PC Pins
• Identical physical dimensions: Rectangular - 0.260" x 0.330" Face (6.60mm x 8.38mm)
• Same series: Trimpot® 3329 - Sealed

The primary distinction between these parts is RoHS compliance status, with the 3329W-1-502LF meeting ROHS3 compliance requirements.

Parameter Comparison
