Substitute Part Grouping Explanation

Substitution of the 3352T-1-202 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical resistance value (2 kOhms), power rating (0.5W), tolerance (±20%), number of turns (1), adjustment type (top adjustment), physical dimensions (0.350" Dia x 0.150" H), termination style (PC Pins), and mounting configuration (through hole). The primary distinction between the main part and its substitute lies in RoHS compliance status and resulting inventory availability. The 3352T-1-202LF variant meets ROHS3 compliance requirements while preserving all functional and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 3352T-1-202LF serves as the direct substitute for the 3352T-1-202 when RoHS3 compliance is required. Both parts maintain identical electrical performance and mechanical compatibility. Selection between these variants depends on regulatory requirements: the 3352T-1-202 is suitable for applications without RoHS compliance mandates, while the 3352T-1-202LF is required for designs subject to ROHS3 regulations. Inventory considerations favor the 3352T-1-202LF, which maintains higher stock levels (3894 Pcs versus 1144 Pcs). Both parts carry Active product status and are manufactured by Bourns Inc., ensuring continued availability and technical support.

Frequently Asked Questions (FAQ)

Q: Are the 3352T-1-202 and 3352T-1-202LF electrically interchangeable?

A: Yes. Both parts deliver identical electrical performance with 2 kOhms resistance, 0.5W power rating, and ±20% tolerance. The "LF" designation indicates lead-free construction for RoHS3 compliance, not a change in electrical characteristics.

Q: What is the physical compatibility between these parts?

A: Complete physical compatibility exists. Both parts share identical dimensions (0.350" Dia x 0.150" H), PC pin termination, through-hole mounting configuration, and top adjustment mechanism. Direct PCB substitution is possible without layout modifications.

Q: When should I select the 3352T-1-202LF over the 3352T-1-202?

A: Select the 3352T-1-202LF when your application or supply chain requires ROHS3 compliance. This includes most consumer electronics, automotive applications subject to EU regulations, and OEM procurement standards that mandate lead-free components.

Q: Does the RoHS compliance difference affect performance or reliability?

A: No. RoHS compliance reflects manufacturing process and material composition (lead-free solder and termination), not functional performance. Both variants maintain identical electrical specifications and moisture sensitivity ratings.

Q: Are there any packaging or ordering differences?

A: Both parts are supplied in bulk packaging. The primary difference is inventory availability, with the 3352T-1-202LF maintaining higher stock levels. Consult current inventory status for procurement planning.
