Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3352P-1-202 is determined by strict equivalence across all critical 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 0.210" H), termination style (PC Pins), and mounting configuration (through hole). The primary distinction between the main part and its substitute relates to RoHS compliance status and associated lead-free processing, which does not alter functional performance or mechanical compatibility when all other parameters remain constant.

Engineering Selection Recommendations

The 3352P-1-202LF serves as a direct functional equivalent to the 3352P-1-202, with the primary distinction being RoHS3 compliance. Selection between these parts should be based on regulatory and procurement requirements. The 3352P-1-202 remains suitable for applications without RoHS mandates or for legacy system maintenance. The 3352P-1-202LF is required for new designs or applications subject to RoHS3 regulations. Both parts maintain identical electrical performance, mechanical fit, and thermal characteristics. Current inventory availability shows 1017 units of the standard version and 741 units of the lead-free variant, supporting both procurement scenarios.

Frequently Asked Questions (FAQ)

Q: Are the 3352P-1-202 and 3352P-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 processing and RoHS3 compliance, not functional differences.

Q: Can the 3352P-1-202LF be used as a direct replacement in existing designs using the 3352P-1-202?

A: Yes, provided the application has no specific requirement for the non-compliant version. The mechanical dimensions, termination style, and mounting configuration are identical, ensuring PCB compatibility without redesign.

Q: What is the significance of the "LF" suffix in the 3352P-1-202LF part number?

A: The LF suffix denotes lead-free construction and RoHS3 compliance. This reflects manufacturing process changes to eliminate restricted substances while maintaining all functional and mechanical specifications.

Q: Are there any performance differences between RoHS-compliant and non-compliant versions of this potentiometer?

A: No. RoHS compliance status reflects manufacturing standards and material composition, not electrical or mechanical performance. Both versions operate identically within specified parameters.

Q: What moisture sensitivity level applies to both versions?

A: Both the 3352P-1-202 and 3352P-1-202LF carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
