3386M-1-202LF Trimmer Potentiometer: Equivalent & Substitute Parts

Part Overview

The Bourns 3386M-1-202LF is a 2 kOhm, 0.5W through-hole trimmer potentiometer with cermet resistive material, top adjustment, and PC pin termination. This component is classified as Active product status. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from equivalent alternatives that maintain identical electrical specifications and mechanical compatibility within the application circuit.

Substitute Part Grouping Explanation

Substitution eligibility for the 3386M-1-202LF is determined by strict equivalence across the following critical parameters: resistance value (2 kOhms), 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), and termination style (PC pins). All identified substitute parts—25PR2KLF, 72PR2KLF, and 82PR2KLF—satisfy these electrical and functional requirements. Physical dimensions and packaging formats may vary within the substitute group; however, these variations do not affect electrical performance or circuit functionality when applied within standard PCB design constraints.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and satisfy regulatory compliance requirements (RoHS and REACH). Selection among 3386M-1-202LF, 25PR2KLF, 72PR2KLF, and 82PR2KLF is determined by physical form factor constraints within the PCB layout. The 3386M-1-202LF and 72PR2KLF share identical square footprints (9.53mm x 9.53mm), enabling direct mechanical substitution. The 25PR2KLF features a smaller square footprint (6.86mm x 6.86mm), suitable for space-constrained applications. The 82PR2KLF employs a round form factor (6.35mm diameter), requiring PCB layout modification. Packaging format (tube versus bulk) reflects inventory and procurement considerations and does not affect component performance.

Frequently Asked Questions (FAQ)

Q: Can 25PR2KLF replace 3386M-1-202LF in an existing PCB design? A: Electrical substitution is valid; however, the 25PR2KLF footprint (6.86mm x 6.86mm square) differs from the 3386M-1-202LF footprint (9.53mm x 9.53mm square). PCB layout modification is required.

Q: What is the primary difference between 72PR2KLF and 3386M-1-202LF? A: Both parts share identical electrical specifications and square footprints (9.53mm x 9.53mm). The primary difference is packaging format: 3386M-1-202LF is supplied in tubes, while 72PR2KLF is supplied in bulk.

Q: Is 82PR2KLF mechanically compatible with 3386M-1-202LF? A: Electrical compatibility is confirmed. Mechanical compatibility requires PCB redesign due to the round form factor (6.35mm diameter) versus the square form factor (9.53mm x 9.53mm) of the 3386M-1-202LF.

Q: Do all substitute parts meet the same regulatory standards? A: All parts are RoHS compliant and REACH unaffected. The 3386M-1-202LF, 72PR2KLF, and 82PR2KLF carry ROHS3 certification, while 25PR2KLF carries RoHS certification. All share identical ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Q: Are there inventory differences among the substitute parts? A: Yes. Current inventory levels are: 3386M-1-202LF (864 pcs), 25PR2KLF (5508 pcs), 72PR2KLF (1401 pcs), and 82PR2KLF (1993 pcs). Availability may influence procurement decisions.
