Bourns 3366P-1-502 Equivalent & Substitute Parts

Part Overview

The Bourns 3366P-1-502 is a 5 kOhm, 0.5W through-hole trimmer potentiometer with PC pin termination and top adjustment. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The 3366 series has been superseded by the Trimpot® 3362 sealed series, which maintains electrical compatibility while offering improved availability and active product status.

Substitute Part Grouping Explanation

The 3366P-1-502 has one manufacturer-recommended substitute: the Bourns 3362P-1-502. This substitution is valid based on the following matching parameters:

  • Resistance value: 5 kOhms (identical)
  • Power rating: 0.5W / 1/2W (identical)
  • Tolerance: ±10% (identical)
  • Temperature coefficient: ±100ppm/°C (identical)
  • Number of turns: 1 Turn (identical)
  • Adjustment type: Top Adjustment (identical)
  • Resistive material: Cermet (identical)
  • Mounting type: Through Hole (identical)
  • Termination style: PC Pins (identical)

The 3362P series represents the active product line replacement, with sealed construction providing enhanced environmental protection compared to the obsolete 3366P series.

Engineering Selection Recommendations

The 3362P-1-502 is the manufacturer-recommended substitute for the obsolete 3366P-1-502. All critical electrical parameters are identical, ensuring functional equivalence in circuit applications. The 3362P series is classified as active product status with current manufacturing and distribution support.

The 3362P-1-502 carries RoHS non-compliant and REACH Affected designations. Applications requiring RoHS compliance or REACH compliance must evaluate alternative component families outside this substitution group.

Physical dimensions differ slightly between the two models. The 3366P-1-502 features a square face (7.00mm x 7.00mm), while the 3362P-1-502 has a rectangular face (6.99mm x 6.60mm). PCB layout verification is required to confirm mechanical fit in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 3362P-1-502 directly replace the 3366P-1-502 in existing designs?

A: Electrical substitution is valid. All resistance, power, tolerance, and temperature coefficient specifications are identical. Physical dimensions differ slightly; PCB layout must be verified for mechanical compatibility.

Q: What is the primary difference between the 3366P and 3362P series?

A: The 3362P series features sealed construction, providing enhanced environmental protection. The 3366P series is obsolete; the 3362P is the active manufacturer product line.

Q: Are there compliance differences between these parts?

A: The 3362P-1-502 is RoHS non-compliant and REACH Affected. Applications with compliance requirements must evaluate alternative component families.

Q: What packaging is available for the 3362P-1-502?

A: The 3362P-1-502 is supplied in Tube packaging.

Q: Are the PC pin terminations identical between both models?

A: Yes. Both models use PC pin termination style for through-hole mounting. Physical pin spacing should be verified against PCB design files.
