Substitute Part Grouping Explanation

Substitution of the 3366P-1-202 is determined by strict equivalence across the following critical parameters:

  • Resistance value: 2 kOhms
  • 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-1-202 meets all these criteria and is the manufacturer-recommended substitute. The 3362 series represents the active, current-generation equivalent to the obsolete 3366 series, with identical electrical specifications and compatible mechanical form factors for PC pin through-hole applications.

Engineering Selection Recommendations

The 3362P-1-202 is the appropriate substitute for the obsolete 3366P-1-202 based on the following factors:

  • Electrical equivalence: All critical electrical parameters (resistance, power rating, tolerance, temperature coefficient) are identical.
  • Mechanical compatibility: Both parts feature PC pin through-hole termination with comparable face dimensions (7.00mm vs. 6.99mm x 6.60mm), suitable for standard PCB layouts designed for the 3366 series.
  • Product status: The 3362P-1-202 is active and in production, ensuring long-term availability and supply chain continuity.
  • Regulatory compliance: The 3362P-1-202 is RoHS non-compliant and REACH Affected. Design teams must evaluate regulatory requirements for their specific applications and markets.

Frequently Asked Questions (FAQ)

Q: Can the 3362P-1-202 be used as a direct replacement for the 3366P-1-202?

A: Yes. The 3362P-1-202 meets all electrical specifications of the 3366P-1-202 and is mechanically compatible for PC pin through-hole PCB applications. Minor dimensional differences (face size) are within acceptable tolerances for standard PCB layouts.

Q: What is the primary reason for substitution?

A: The 3366P-1-202 is obsolete. The 3362P-1-202 is the active, manufacturer-recommended equivalent from Bourns Inc.

Q: Are there differences in packaging between these parts?

A: The 3366P-1-202 packaging is not specified in available documentation. The 3362P-1-202 is supplied in Tube packaging. Confirm packaging requirements with your procurement or supply chain team.

Q: What compliance certifications apply to the 3362P-1-202?

A: The 3362P-1-202 is RoHS non-compliant and REACH Affected. Verify compliance requirements for your target markets and applications before design implementation.

Q: Are the face dimensions identical between the two parts?

A: No. The 3366P-1-202 has a square face of 0.276" x 0.276" (7.00mm x 7.00mm), while the 3362P-1-202 has a rectangular face of 0.275" x 0.260" (6.99mm x 6.60mm). Both dimensions are compatible with standard through-hole PCB layouts for trimmer potentiometers.
