Bourns 3386F-1-201 Trimmer Potentiometer: Equivalent & Substitute Parts

Part Overview

The Bourns 3386F-1-201 is a 200 Ohm, 0.5W through-hole trimmer potentiometer with PC pin termination, top adjustment, and cermet resistive material. This sealed Trimpot® 3386 series component is designed for applications requiring precision variable resistance in compact form factors. The part is currently active in production. Equivalent and substitute parts may be required due to inventory availability, compliance requirements, or specific application constraints such as package dimensions or regulatory certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386F-1-201 is determined by matching the following core electrical and mechanical parameters: 200 Ohm resistance value, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, single-turn adjustment, top adjustment type, cermet resistive material, through-hole mounting, and PC pin termination.

The identified substitute parts maintain these critical parameters. Variations in physical dimensions (face size or form factor) and packaging format (tube versus bulk) do not affect electrical compatibility but may impact mechanical fit and procurement logistics. Compliance certifications (RoHS, REACH) differ between parts and should be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

3386F-1-201LF (Bourns Inc.): Direct equivalent from the same manufacturer with identical electrical specifications and form factor. Offers improved compliance status with ROHS3 certification and REACH unaffected designation. Recommended for new designs or applications with regulatory compliance requirements.

25PR200LF (TT Electronics/BI): Electrically equivalent with all core parameters matched. Smaller physical footprint (0.270" square versus 0.375" square) requires PCB layout verification for mechanical fit. RoHS compliant and REACH unaffected. Suitable for space-constrained applications.

82PR200LF (TT Electronics / BI Technologies): Electrically equivalent with all core parameters matched. Round form factor (0.250" diameter) differs from original square geometry and requires mechanical compatibility assessment. ROHS3 compliant and REACH unaffected. Supplied in bulk packaging rather than tube format.

Frequently Asked Questions (FAQ)

Q: Can the 3386F-1-201 be directly replaced with the 3386F-1-201LF? A: Yes. Both parts are manufactured by Bourns Inc., share identical electrical specifications, and have the same physical dimensions. The primary difference is improved compliance status (ROHS3 and REACH unaffected) in the 3386F-1-201LF variant.

Q: Are the TT Electronics parts (25PR200LF and 82PR200LF) electrically compatible with the Bourns 3386F-1-201? A: Yes. All substitute parts maintain the same resistance value (200 Ohms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), adjustment type (top), resistive material (cermet), mounting method (through hole), and termination style (PC pins). Electrical performance is equivalent.

Q: What are the mechanical differences between substitute parts? A: The 3386F-1-201 and 3386F-1-201LF are square (0.375" x 0.375"). The 25PR200LF is smaller and square (0.270" x 0.270"). The 82PR200LF is round (0.250" diameter). These dimensional differences may affect PCB layout compatibility and should be verified before substitution.

Q: Does packaging format affect part selection? A: Packaging format (tube versus bulk) affects procurement and handling but does not impact electrical or mechanical performance. The 3386F-1-201, 3386F-1-201LF, and 25PR200LF are supplied in tubes. The 82PR200LF is supplied in bulk. Selection should align with inventory management and assembly process requirements.

Q: Which substitute part should be selected for new designs? A: For new designs, the 3386F-1-201LF is recommended as the primary choice due to identical form factor and improved compliance certifications (ROHS3 and REACH unaffected). Alternative parts may be selected if specific dimensional constraints or packaging requirements necessitate different form factors.

Q: Are there compliance differences between the parts? A: Yes. The original 3386F-1-201 is RoHS non-compliant and REACH affected. The 3386F-1-201LF, 25PR200LF, and 82PR200LF are all RoHS compliant (or ROHS3 compliant) and REACH unaffected. Applications subject to regulatory compliance mandates should specify compliant variants.
