Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical 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), and termination style (PC pins). All identified substitutes meet these electrical and mechanical requirements. Packaging format and RoHS compliance status are secondary considerations that do not affect functional interchangeability in the circuit.

Parameter Comparison

Engineering Selection Recommendations

The 3339H-1-202LF is a direct substitute within the Trimpot® 3339 - Sealed series, offering identical electrical specifications and mechanical form factor. The primary distinction is RoHS3 compliance, making this part suitable for applications subject to RoHS regulations.

The PV12P202A01B00 from the PV12 series provides functional equivalence across all critical electrical parameters and maintains mechanical compatibility within tolerance. The dimensional difference of 0.001" (0.02mm) in diameter is negligible for through-hole mounting applications. This part is supplied in bulk packaging and carries ROHS3 compliance. Selection between series should be based on procurement requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 3339H-1-202LF be used as a direct replacement for 3339H-1-202? A: Yes. Both parts share identical electrical specifications, tolerance, temperature coefficient, and mechanical form factor. The LF suffix indicates lead-free termination and RoHS3 compliance. Functional interchangeability is complete.

Q: Is PV12P202A01B00 compatible with 3339H-1-202 in circuit applications? A: Yes. The PV12P202A01B00 meets all critical electrical parameters: 2 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 4-turn adjustment, and cermet construction. The 0.001" dimensional variance does not affect through-hole mounting compatibility.

Q: What is the difference between tube and bulk packaging? A: Tube packaging provides individual component protection and is standard for smaller order quantities. Bulk packaging is used for larger volume shipments. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Does RoHS compliance affect electrical performance? A: No. RoHS3 compliance relates to material composition and environmental standards, not electrical characteristics. Parts with different RoHS statuses are electrically equivalent when all other parameters match.

Q: Are there dimensional concerns when substituting between series? A: The PV12P202A01B00 has a diameter of 0.299" compared to 0.300" for the 3339H series. This 0.001" difference is within standard manufacturing tolerance and does not impact through-hole PCB mounting or mechanical fit.
