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

The identified substitute part maintains full electrical and mechanical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The 3386C-1-504LF serves as a direct electrical and mechanical equivalent to the 3386C-1-504. Both parts are manufactured by Bourns Inc. within the Trimpot® 3386 sealed series and maintain identical specifications across all critical functional parameters: resistance, power rating, tolerance, temperature coefficient, adjustment mechanism, and physical dimensions.

The primary distinction between these parts lies in regulatory compliance status. The 3386C-1-504LF is ROHS3 compliant and REACH unaffected, whereas the 3386C-1-504 is RoHS non-compliant and REACH affected. Selection between these parts should be based on application requirements regarding environmental and regulatory compliance mandates. Both parts carry identical ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Frequently Asked Questions (FAQ)
