Substitute Part Grouping Explanation

Substitution eligibility for the 3386W-1-201 is determined by strict equivalence across the following critical parameters:

• Resistance value: 200 Ohms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1 Turn
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical size: Square - 0.375" x 0.375" (9.53mm x 9.53mm)
• Series: Trimpot® 3386 - Sealed

The identified substitute part maintains identical electrical and mechanical specifications, with differences limited to RoHS compliance status and REACH regulatory classification.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386W-1-201 and 3386W-1-201LF are functionally equivalent and electrically interchangeable for applications requiring a 200 Ohm, 0.5W trimmer potentiometer with the specified parameters.

Selection between these parts should be based on regulatory and compliance requirements:

• 3386W-1-201LF is the preferred choice for applications subject to RoHS3 compliance mandates or where REACH-unaffected status is required by procurement specifications or end-market regulations.

• 3386W-1-201 remains suitable for applications where RoHS non-compliance is acceptable and REACH-affected status does not present a constraint.

Both parts share identical electrical performance, mechanical dimensions, and packaging specifications. The "LF" suffix in the 3386W-1-201LF designation indicates lead-free termination and RoHS3 compliance.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are identical in resistance value (200 Ohms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), adjustment type (side adjustment), resistive material (cermet), mounting type (through hole), termination style (PC pins), and physical dimensions (0.375" x 0.375"). They are direct electrical and mechanical substitutes.

Q: What is the difference between these two part numbers?

A: The primary differences are regulatory compliance status. The 3386W-1-201LF is ROHS3 compliant and REACH unaffected, while the 3386W-1-201 is RoHS non-compliant and REACH affected. The "LF" designation indicates lead-free construction.

Q: Can I use 3386W-1-201LF as a drop-in replacement for 3386W-1-201?

A: Yes, the 3386W-1-201LF is a direct drop-in replacement from an electrical and mechanical standpoint. Verify that your application's compliance requirements align with the ROHS3 and REACH-unaffected status of the LF variant.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical performance across all specified electrical parameters and mechanical characteristics.

Q: Which part should I specify for new designs?

A: For new designs, specify the 3386W-1-201LF to ensure compliance with current RoHS3 and REACH regulations, unless your application explicitly permits the use of RoHS non-compliant components.

Q: What is the packaging format for both parts?

A: Both parts are supplied in tube packaging.
