Substitute Part Grouping Explanation

Substitute parts for the 3386P-1-500 are identified based on strict equivalence across the following critical parameters:

• Resistance value: 50 Ohms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1 Turn
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Square - 0.375" x 0.375" (9.53mm x 9.53mm)
• Series: Trimpot® 3386 - Sealed

The 3386P-1-500LF meets all these criteria and is classified as a direct manufacturer substitute. The primary distinction between the main part and its substitute relates to RoHS compliance status and REACH classification, which do not affect electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386P-1-500 and 3386P-1-500LF are active production parts from Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements:

The 3386P-1-500LF is recommended for applications subject to RoHS3 compliance requirements or where REACH-unaffected status is mandated. The 3386P-1-500 remains suitable for applications without RoHS compliance constraints. Both parts are classified under ECCN EAR99 and share the same HTSUS code, indicating equivalent trade classification.

Frequently Asked Questions (FAQ)

Q: Can the 3386P-1-500LF be used as a direct replacement for the 3386P-1-500?

A: Yes. Both parts are electrically and mechanically identical. The 3386P-1-500LF differs only in RoHS and REACH compliance status. Direct substitution is valid for applications where compliance requirements align with the substitute part's certifications.

Q: What is the significance of the "LF" suffix in the 3386P-1-500LF part number?

A: The "LF" designation indicates lead-free construction and RoHS3 compliance. This affects material composition and manufacturing processes but does not alter electrical performance or mechanical fit.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts feature a square form factor of 0.375" x 0.375" (9.53mm x 9.53mm) with identical PC pin termination and through-hole mounting. PCB layout and mechanical clearances are interchangeable.

Q: What are the key parameters that determine substitutability for this trimmer potentiometer?

A: Substitutability is determined by matching resistance value (50 Ohms), 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").

Q: Can these parts be used in applications requiring RoHS compliance?

A: The 3386P-1-500LF is RoHS3 compliant and suitable for RoHS-regulated applications. The 3386P-1-500 is RoHS non-compliant and should not be used in applications with RoHS requirements.
