Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3339P-1-202 is determined by strict equivalence across the following parameters: resistance value (2 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (4), adjustment type (top adjustment), resistive material (Cermet), mounting type (through hole), termination style (PC pins), and physical dimensions (0.300" diameter). Variations in RoHS compliance status, packaging format (tube versus bulk), and series designation do not affect electrical or mechanical substitutability. The identified substitute parts maintain all critical performance specifications while differing only in compliance certifications and distribution packaging.

Parameter Comparison

Engineering Selection Recommendations

The 3339P-1-202LF serves as the direct equivalent for applications requiring ROHS3 compliance while maintaining identical electrical specifications and tube packaging. This part is suitable for designs subject to RoHS regulations without modification to PCB layout or circuit design.

The PV12P202A01B00 provides functional equivalence with ROHS3 compliance and bulk packaging availability. The physical dimension variance (0.299" versus 0.300" diameter) represents a 0.01mm difference and does not affect mechanical fit in standard through-hole applications. This part is appropriate for high-volume procurement scenarios where bulk packaging reduces per-unit cost.

Selection between these substitutes depends on compliance requirements and packaging preferences. All three parts maintain identical electrical performance and are suitable for direct substitution in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can 3339P-1-202LF replace 3339P-1-202 in existing designs? A: Yes. The 3339P-1-202LF is electrically and mechanically identical to the 3339P-1-202, differing only in RoHS compliance status and packaging format. No circuit modifications are required.

Q: What is the significance of the 0.01mm dimension difference between 3339P-1-202 and PV12P202A01B00? A: The dimension variance (0.300" versus 0.299" diameter) is within standard manufacturing tolerances for through-hole components and does not affect PCB hole fit or mechanical performance.

Q: Is PV12P202A01B00 compatible with designs specified for 3339P-1-202? A: Yes. The PV12P202A01B00 maintains all critical electrical and mechanical parameters. The difference in series designation (PV12 versus Trimpot® 3339) reflects product line classification only and does not impact functional compatibility.

Q: What packaging differences exist between these parts? A: The 3339P-1-202 and 3339P-1-202LF are supplied in tube packaging. The PV12P202A01B00 is supplied in bulk packaging. Tube packaging is suitable for lower-volume applications, while bulk packaging is optimized for high-volume manufacturing.

Q: Are all three parts suitable for RoHS-regulated applications? A: The 3339P-1-202 is RoHS non-compliant. The 3339P-1-202LF and PV12P202A01B00 are both ROHS3 compliant and suitable for applications subject to RoHS regulations.
