Bourns 3366P-1-201 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The Bourns 3366P-1-201 is a 200 Ohm, 0.5W through-hole trimmer potentiometer with PC pin termination and top adjustment. This part is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and component procurement. The 3366 series represents an earlier generation of Bourns trimmer potentiometers, with the 3362 series providing the current active equivalent.

Substitute Part Grouping Explanation

Substitution of the 3366P-1-201 is determined by matching the following critical parameters:

  • Resistance value: 200 Ohms
  • Power rating: 0.5W
  • Tolerance: ±10%
  • Temperature coefficient: ±100ppm/°C
  • Number of turns: 1 Turn
  • Adjustment type: Top Adjustment
  • Resistive material: Cermet
  • Mounting type: Through Hole
  • Termination style: PC Pins

The Bourns 3362P-1-201 meets all these criteria and serves as the manufacturer-recommended substitute. Minor dimensional variations between the square face of the 3366P and rectangular face of the 3362P are acceptable within standard PCB layout tolerances for through-hole trimmer potentiometers.

Engineering Selection Recommendations

The 3362P-1-201 is the appropriate substitute for the obsolete 3366P-1-201. Both parts share identical electrical specifications and functional characteristics. The 3362P-1-201 is currently in active production status, ensuring long-term availability and supply chain continuity.

The dimensional difference between the square face of the 3366P and the rectangular face of the 3362P requires PCB layout verification. The 3362P-1-201 footprint is slightly smaller in one axis (0.260" versus 0.276"), which may require minor PCB artwork adjustments depending on existing layout constraints.

The 3362P-1-201 is RoHS non-compliant and REACH Affected. If RoHS compliance is required for your application, alternative part families must be evaluated outside the scope of this direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the 3362P-1-201 be used as a direct replacement for the 3366P-1-201?

A: Yes. Both parts have identical electrical specifications: 200 Ohms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, top adjustment, cermet material, through-hole mounting, and PC pin termination. PCB layout verification is required due to minor dimensional differences.

Q: What is the dimensional difference between these parts?

A: The 3366P-1-201 has a square face of 0.276" x 0.276" (7.00mm x 7.00mm). The 3362P-1-201 has a rectangular face of 0.275" x 0.260" (6.99mm x 6.60mm). The 3362P is slightly smaller in one axis.

Q: Why is the 3366P-1-201 obsolete?

A: The 3366 series has been superseded by the 3362 series in Bourns' product portfolio. The 3362 series offers improved sealing and is the current active offering for this class of trimmer potentiometer.

Q: Are there any compliance differences between these parts?

A: The 3362P-1-201 is RoHS non-compliant and REACH Affected. If your application requires RoHS compliance, alternative part families must be evaluated.

Q: What packaging is available for the 3362P-1-201?

A: The 3362P-1-201 is supplied in Tube packaging.
