Substitute Part Grouping Explanation

Substitution between the 3386X-1-201 and 3386X-1-201LF is based on identical electrical and mechanical specifications. Both parts share the same core parameters: 200 Ohm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn side adjustment, cermet resistive material, through-hole mounting, PC pin termination, and identical physical dimensions (9.53mm x 9.53mm square form factor).

The primary distinction between these parts lies in regulatory compliance status. The 3386X-1-201LF variant incorporates RoHS3 compliance and REACH unaffected status, whereas the 3386X-1-201 is RoHS non-compliant and REACH affected. Both parts maintain the same ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Parameter Comparison

Engineering Selection Recommendations

Selection between 3386X-1-201 and 3386X-1-201LF should be determined by regulatory and compliance requirements applicable to the end application and target market.

The 3386X-1-201LF is the appropriate choice for applications subject to RoHS3 directives or REACH compliance mandates. This variant is suitable for European Union markets and applications where lead-free and restricted substance compliance is required.

The 3386X-1-201 remains suitable for applications where RoHS3 and REACH compliance are not regulatory requirements. Both parts are active products from Bourns Inc. and maintain identical electrical performance and physical form factors.

Frequently Asked Questions (FAQ)

Q: Are the 3386X-1-201 and 3386X-1-201LF electrically interchangeable?

A: Yes. Both parts have identical electrical specifications: 200 Ohm resistance, 0.5W power rating, ±10% tolerance, and ±100ppm/°C temperature coefficient. They are functionally equivalent in circuit applications.

Q: What does the "LF" suffix indicate in the 3386X-1-201LF part number?

A: The "LF" suffix indicates lead-free construction and RoHS3 compliance. This variant is formulated to meet European Union RoHS directives and REACH regulations.

Q: Can I use 3386X-1-201LF as a direct replacement for 3386X-1-201 in existing designs?

A: Yes, from an electrical and mechanical standpoint. The 3386X-1-201LF maintains identical resistance, power rating, tolerance, temperature coefficient, adjustment type, resistive material, mounting configuration, termination style, and physical dimensions. Substitution is valid for circuit functionality and PCB layout compatibility.

Q: Are there compliance considerations when selecting between these parts?

A: Yes. If your application or target market requires RoHS3 compliance or REACH compliance, the 3386X-1-201LF is the appropriate selection. If these compliance requirements do not apply, either part may be used based on availability and procurement strategy.

Q: Do both parts use the same packaging?

A: Yes. Both the 3386X-1-201 and 3386X-1-201LF are supplied in tube packaging.

Q: What is the physical footprint of these trimmer potentiometers?

A: Both parts have a square form factor measuring 0.375" x 0.375" (9.53mm x 9.53mm). This dimension applies to the face of the component and is consistent across both variants.
