Bourns 3296P-1-202 Trimmer Potentiometer: Equivalent & Substitute Parts

Part Overview

The Bourns 3296P-1-202 is a 2 kOhm, 0.5W through-hole trimmer potentiometer with PC pin termination and side adjustment capability. This sealed Trimpot® 3296 series component features cermet resistive material and 25-turn adjustment resolution, designed for precision tuning applications in electronic circuits. The part is currently active in production. Substitute parts may be required due to inventory availability, RoHS compliance requirements, or dimensional constraints in specific PCB layouts.

Substitute Part Grouping Explanation

Substitute parts for the 3296P-1-202 are classified based on electrical parameter equivalence and mechanical compatibility. All substitute candidates maintain identical electrical specifications: 2 kOhm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 25-turn adjustment, side adjustment type, cermet material, through-hole mounting, and PC pin termination. Substitution eligibility is determined by these core electrical and functional parameters. Dimensional variations and RoHS compliance status are secondary considerations that may influence selection based on application requirements.

Engineering Selection Recommendations

3296P-1-202LF: This part is electrically and mechanically identical to the main part number with identical face dimensions (9.53mm x 4.83mm). The primary distinction is ROHS3 compliance status. Selection of this substitute is appropriate when RoHS3 compliance is a design requirement or regulatory mandate.

3299P-1-202: This part maintains all electrical specifications but features a different dimensional footprint (6.10mm x 9.53mm face). The Trimpot® 3299 series geometry differs from the 3296 series. This substitute is suitable only when PCB layout constraints accommodate the alternative dimensions and the Trimpot® 3299 series form factor is acceptable.

PV36P202C01B00: This part maintains all electrical specifications with dimensions (9.60mm x 5.00mm) that approximate the main part. The PV36 series represents an alternative product line from Bourns. This substitute is suitable when ROHS3 compliance is required and dimensional tolerance of approximately ±0.1mm is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can 3296P-1-202LF be used as a direct replacement for 3296P-1-202?

A: Yes. The 3296P-1-202LF is electrically and dimensionally identical to the 3296P-1-202. The only difference is RoHS3 compliance status. Direct substitution is possible without circuit modification.

Q: What is the primary difference between 3299P-1-202 and 3296P-1-202?

A: Both parts share identical electrical specifications. The 3299P-1-202 belongs to the Trimpot® 3299 series and has different face dimensions (6.10mm x 9.53mm versus 9.53mm x 4.83mm). PCB layout compatibility must be verified before substitution.

Q: Is PV36P202C01B00 compatible with the original 3296P-1-202 design?

A: PV36P202C01B00 maintains all electrical specifications and has similar dimensions (9.60mm x 5.00mm). The part belongs to the PV36 series rather than the Trimpot® 3296 series. Dimensional tolerance of approximately ±0.1mm exists. Mechanical fit verification is recommended.

Q: Which substitute should be selected for RoHS3 compliance?

A: Both 3296P-1-202LF and PV36P202C01B00 carry ROHS3 compliance status. The 3296P-1-202LF is preferred if identical series and dimensions are required. PV36P202C01B00 is an alternative if series flexibility exists.

Q: Are all substitutes rated for the same power dissipation?

A: Yes. All parts listed maintain 0.5W power rating, ±10% tolerance, and ±100ppm/°C temperature coefficient. Electrical performance is equivalent across all substitutes.

Q: What inventory levels are available for each part?

A: 3296P-1-202: 2100 pcs; 3296P-1-202LF: 3900 pcs; 3299P-1-202: 893 pcs; PV36P202C01B00: 911 pcs.
