3386Y-1-201LF Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The Bourns 3386Y-1-201LF is a 200 Ohm, 0.5W through-hole trimmer potentiometer with cermet resistive material, top adjustment, and PC pin termination. This component is part of the Trimpot® 3386 sealed series and maintains Active product status. Equivalent and substitute parts are identified when component availability is limited, procurement lead times are extended, or design flexibility permits alternative form factors while maintaining electrical and mechanical compatibility within specified parameters.

Substitute Part Grouping Explanation

Substitute parts for the 3386Y-1-201LF are qualified based on matching the following critical electrical and mechanical parameters:

• Resistance value: 200 Ohms
• Power rating: 0.5W (1/2W)
• 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

The identified substitutes (25PR200LF and 82PR200LF) satisfy all electrical parameters and core mechanical requirements. Variations in physical dimensions and packaging format do not affect functional equivalence within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and satisfy RoHS compliance requirements. The 3386Y-1-201LF and 82PR200LF are both ROHS3 Compliant, while the 25PR200LF is RoHS Compliant. Selection between the main part and substitutes depends on physical space constraints and packaging requirements:

• The 3386Y-1-201LF (square, 9.53mm) is the primary specification.
• The 25PR200LF (square, 6.86mm) provides a smaller footprint within the same form factor.
• The 82PR200LF (round, 6.35mm) offers the most compact profile and is available in bulk packaging.

All parts share identical electrical specifications and are suitable for direct functional replacement in applications where the specified parameters govern performance.

Frequently Asked Questions (FAQ)

Q: Can the 25PR200LF or 82PR200LF be used as direct replacements for the 3386Y-1-201LF?

A: Yes. All three parts match the critical electrical parameters: 200 Ohms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, top adjustment, cermet material, through-hole mounting, and PC pin termination. Functional equivalence is established through these parameters.

Q: What are the physical differences between these parts?

A: The 3386Y-1-201LF has a square face of 9.53mm x 9.53mm. The 25PR200LF has a smaller square face of 6.86mm x 6.86mm. The 82PR200LF has a round form factor with a 6.35mm diameter. These dimensional variations do not affect electrical performance but may impact PCB layout and available mounting space.

Q: Are there packaging differences?

A: The 3386Y-1-201LF and 25PR200LF are supplied in Tube packaging. The 82PR200LF is supplied in Bulk packaging. Packaging format does not affect component functionality.

Q: Do all parts meet the same compliance standards?

A: The 3386Y-1-201LF and 82PR200LF are ROHS3 Compliant. The 25PR200LF is RoHS Compliant. All three parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: Which substitute should be selected if PCB space is limited?

A: The 82PR200LF offers the smallest physical footprint with its 6.35mm round form factor. If a square form factor is required, the 25PR200LF provides a smaller square profile (6.86mm) compared to the original 3386Y-1-201LF (9.53mm).
