Substitute Part Grouping Explanation

The 3386C-1-502LF is a direct substitute for the 3386C-1-502 based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Resistance value: 5 kOhms (exact match)
• Power rating: 0.5W / 1/2W (exact match)
• Tolerance: ±10% (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Number of turns: 1 (exact match)
• Adjustment type: Side Adjustment (exact match)
• Resistive material: Cermet (exact match)
• Mounting type: Through Hole (exact match)
• Termination style: PC Pins (exact match)
• Physical dimensions: Square - 0.375" x 0.375" Face (9.53mm x 9.53mm) (exact match)
• Series: Trimpot® 3386 - Sealed (exact match)

The primary distinction between these parts is regulatory compliance status and lead-free termination processing.

Parameter Comparison

Engineering Selection Recommendations

Selection between 3386C-1-502 and 3386C-1-502LF is determined by regulatory compliance requirements:

The 3386C-1-502LF is the preferred selection for applications subject to RoHS3 compliance mandates or REACH-restricted substance regulations. This variant maintains full electrical and mechanical equivalence while meeting current environmental compliance standards.

The 3386C-1-502 remains suitable for applications without RoHS3 or REACH compliance requirements. Both parts are active products from Bourns Inc. and share identical functional specifications.
