Key Parameters

Substitute Part Grouping Explanation

Substitution for the 3386W-1-504 is determined by matching the following critical parameters:

• Resistance value: 500 kOhms
• Power rating: 0.5W
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Square - 0.375" x 0.375" face

The 3386W-1-504LF meets all these electrical and mechanical parameters and is classified as a direct manufacturer substitute within the Bourns Trimpot® 3386 sealed series.

Parameter Comparison

Engineering Selection Recommendations

The 3386W-1-504LF is a direct electrical and mechanical equivalent to the 3386W-1-504. Both parts are manufactured by Bourns Inc. and share identical functional specifications within the Trimpot® 3386 sealed series.

The primary distinction between these parts is regulatory compliance status. The 3386W-1-504LF carries ROHS3 compliance and REACH Unaffected status, whereas the 3386W-1-504 is RoHS non-compliant and REACH Affected. Selection between these parts should be based on the regulatory requirements of the target application and end market.

Both parts are active products with current manufacturing status and equivalent inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 3386W-1-504LF be used as a direct replacement for the 3386W-1-504?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value, power rating, tolerance, temperature coefficient, adjustment type, resistive material, mounting configuration, and physical dimensions. The primary difference is regulatory compliance status.

Q: What is the difference between the 3386W-1-504 and 3386W-1-504LF?

A: The 3386W-1-504LF is ROHS3 compliant and REACH Unaffected, while the 3386W-1-504 is RoHS non-compliant and REACH Affected. All electrical and mechanical parameters are identical.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance or REACH compliance, use the 3386W-1-504LF. For applications without these regulatory constraints, either part is functionally equivalent.

Q: Are the physical dimensions identical?

A: Yes. Both parts have a square face measuring 0.375" x 0.375" (9.53mm x 9.53mm) and are through-hole mounted with PC pin termination.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts have identical mounting footprints, pin configurations, and adjustment mechanisms. No PCB redesign is required when substituting between these parts.
