Key Parameters

Substitute Part Grouping Explanation

Substitution for the 3386F-1-205 is determined by matching the following critical parameters: resistance value (2 MOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), termination style (PC pins), and physical dimensions (0.375" x 0.375" square face).

The identified substitute part, 3386F-1-205LF, maintains identical electrical and mechanical specifications within the Trimpot® 3386 sealed series. The primary distinction between the main part and substitute relates to RoHS compliance status and REACH regulatory classification, not functional performance or physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386F-1-205 and 3386F-1-205LF are functionally equivalent for circuit applications requiring 2 MOhm trimmer potentiometers with 0.5W power handling and cermet resistive elements. Selection between these parts should be based on regulatory and compliance requirements:

The 3386F-1-205LF is the preferred selection for applications subject to RoHS3 compliance mandates or REACH regulatory frameworks. This variant eliminates restricted substances and reduces regulatory burden in supply chains requiring lead-free and REACH-compliant components.

The 3386F-1-205 remains suitable for applications without RoHS3 or REACH compliance requirements, or where legacy component specifications are mandated by existing design documentation.

Both parts share identical electrical performance, mechanical dimensions, and mounting characteristics, ensuring direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 3386F-1-205LF be used as a direct replacement for the 3386F-1-205 in existing designs?

A: Yes. The 3386F-1-205LF is electrically and mechanically identical to the 3386F-1-205. All electrical parameters, physical dimensions, and mounting specifications are equivalent. Direct substitution is possible without circuit modification or PCB redesign.

Q: What is the difference between the 3386F-1-205 and 3386F-1-205LF?

A: The primary differences are regulatory compliance classifications. The 3386F-1-205LF is ROHS3 compliant and REACH unaffected, while the 3386F-1-205 is RoHS non-compliant and REACH affected. Electrical and mechanical specifications are identical.

Q: Which part should be selected for new designs?

A: For new designs, the 3386F-1-205LF is recommended due to its ROHS3 compliance and REACH unaffected status, providing better alignment with current regulatory requirements and supply chain standards.

Q: Are there any package or form factor differences between these parts?

A: No. Both parts are packaged in tubes and maintain identical physical dimensions of 0.375" x 0.375" square face (9.53mm x 9.53mm). Mounting type, termination style, and all mechanical specifications are identical.

Q: What inventory status should be considered when selecting between these parts?

A: The 3386F-1-205LF has 944 pcs in stock, while the 3386F-1-205 has 851 pcs in stock. Both are available as new original components. Inventory levels should be evaluated based on project timeline and procurement requirements.
