• Series: Trimpot® 3362 - Sealed

The substitute part 3362W-1-504LF meets all electrical and mechanical parameters required for direct substitution. Differences in RoHS compliance status do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The 3362W-1-504LF is a direct functional equivalent to the 3362W-1-504. Both parts are active products from Bourns Inc. and share identical electrical and mechanical specifications.

Selection between these parts should be based on regulatory requirements:

• Use 3362W-1-504 when RoHS non-compliant components are acceptable or required by application specifications.
• Use 3362W-1-504LF when ROHS3 compliance is mandated by design requirements or customer specifications.

Both parts are subject to REACH regulations and carry the same ECCN (EAR99) and HTSUS (8533.40.8050) classifications. Inventory availability may also influence part selection, with 3362W-1-504LF currently showing higher stock levels (1560 pcs vs. 930 pcs).

Frequently Asked Questions (FAQ)

Q: Can 3362W-1-504LF replace 3362W-1-504 in existing designs?

A: Yes. The 3362W-1-504LF is electrically and mechanically identical to the 3362W-1-504. Both parts have matching resistance, power rating, tolerance, temperature coefficient, adjustment type, and physical dimensions. The only difference is RoHS compliance status.

Q: What does the "LF" suffix indicate in the part number?

A: The "LF" suffix indicates lead-free termination and ROHS3 compliance. This designation reflects the manufacturing process and material composition of the termination, not the functional performance of the component.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts use identical PC pin termination, through-hole mounting, and rectangular form factor. PCB layouts and circuit designs require no modification.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications subject to RoHS directives or customer mandates for lead-free components, use 3362W-1-504LF. For applications without such requirements, either part is acceptable based on availability and cost considerations.

Q: Are both parts still in active production?

A: Yes. Both 3362W-1-504 and 3362W-1-504LF are listed as active products by Bourns Inc.
