• Number of turns: 1
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Square - 0.375" x 0.375" (9.53mm x 9.53mm)
• Series: Trimpot® 3386 - Sealed

The 3386F-1-105LF variant meets all electrical and mechanical specifications while offering improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386F-1-105 and 3386F-1-105LF are functionally equivalent across all electrical and mechanical parameters. Selection between these parts should be based on regulatory and compliance requirements:

The 3386F-1-105LF is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to European Union environmental directives. The 3386F-1-105 is RoHS non-compliant and REACH affected, and should be selected only when compliance exemptions apply or when legacy system requirements mandate the original specification.

Both parts are active products with established inventory availability.

Frequently Asked Questions (FAQ)

Q: Are the 3386F-1-105 and 3386F-1-105LF electrically interchangeable?

A: Yes. Both parts have identical resistance values (1 MOhms), power ratings (0.5W), tolerance (±10%), temperature coefficients (±100ppm/°C), and adjustment characteristics. They are direct electrical equivalents.

Q: What is the difference between these two part numbers?

A: The primary difference is compliance status. The 3386F-1-105LF is ROHS3 compliant and REACH unaffected, while the 3386F-1-105 is RoHS non-compliant and REACH affected. All electrical and mechanical specifications are identical.

Q: Can I use the 3386F-1-105LF as a drop-in replacement for the 3386F-1-105?

A: Yes. The parts share identical physical dimensions (0.375" x 0.375"), mounting type (through hole), termination style (PC pins), and adjustment mechanism (top adjustment). No circuit board modifications are required.

Q: Which part should I specify for new designs?

A: For applications subject to RoHS and REACH regulations, specify the 3386F-1-105LF. Both parts are active and available; the LF variant provides enhanced compliance coverage.

Q: Are there any performance differences between these parts?

A: No. Temperature coefficient, tolerance, resistive material (Cermet), and all other performance parameters are identical between the two variants.
