Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386P-1-204LF is determined by strict equivalence across the following critical parameters:

• Resistance value: 200 kOhms
• 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
• Regulatory compliance: RoHS3 compliant, REACH unaffected

The 82PR200KLF from TT Electronics/BI meets all electrical and mechanical substitution criteria. Physical dimensions differ (square 0.375" face versus round 0.250" diameter), but both configurations accommodate standard through-hole PC pin mounting on circuit boards with appropriate pad spacing.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386P-1-204LF and 82PR200KLF are active products with full regulatory compliance. Selection between these parts should be based on:

• Circuit board layout constraints: The 3386P-1-204LF features a square 0.375" x 0.375" (9.53mm x 9.53mm) footprint, while the 82PR200KLF presents a round 0.250" diameter (6.35mm) footprint. Verify PCB pad spacing and component clearance requirements before substitution.
• Packaging requirements: The 3386P-1-204LF is supplied in tube packaging; the 82PR200KLF is supplied in bulk packaging. Confirm procurement and assembly process compatibility.
• Inventory availability: Current stock levels differ between manufacturers and distributors.

Both parts satisfy identical electrical specifications and regulatory requirements for direct functional substitution in 200 kOhms, 0.5W trimmer potentiometer applications.

Frequently Asked Questions (FAQ)

Q: Can the 82PR200KLF replace the 3386P-1-204LF in existing designs?

A: Yes, provided that the physical footprint difference (square versus round body, different diameters) is compatible with the circuit board layout. All electrical parameters, resistance value, power rating, tolerance, temperature coefficient, and regulatory compliance are equivalent.

Q: What is the primary difference between these two parts?

A: The main differences are physical form factor (square body for 3386P-1-204LF, round body for 82PR200KLF) and packaging format (tube versus bulk). Electrical performance and specifications are identical.

Q: Are both parts RoHS3 compliant?

A: Yes, both the 3386P-1-204LF and 82PR200KLF are ROHS3 compliant and REACH unaffected.

Q: What parameters must remain constant for substitution?

A: Resistance (200 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (top), resistive material (cermet), mounting type (through hole), and termination style (PC pins) must all remain unchanged for functional equivalence.

Q: Does packaging format affect electrical performance?

A: No. Tube and bulk packaging formats do not affect component electrical characteristics. Packaging selection is determined by procurement, storage, and assembly process requirements.
