Bourns 3386C-1-202 Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The Bourns 3386C-1-202 is a 2 kOhms, 0.5W through-hole trimmer potentiometer with PC pin termination and side adjustment capability. This sealed Trimpot® 3386 series component is designed for applications requiring precision resistance adjustment in compact form factors. The part is currently active in production. Alternative models may be required due to RoHS compliance requirements, inventory availability, or specific regulatory certifications needed for end-use applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386C-1-202 is determined by strict equivalence across all critical electrical and mechanical parameters: resistance value (2 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), and physical dimensions (0.375" x 0.375" square face).

The 3386C-1-202LF qualifies as a direct substitute because it maintains identical specifications across all these parameters while belonging to the same Trimpot® 3386 sealed series. The primary distinction between these parts is regulatory compliance status: the 3386C-1-202 is RoHS non-compliant and REACH-affected, whereas the 3386C-1-202LF is RoHS3 compliant and REACH-unaffected.

Parameter Comparison

Engineering Selection Recommendations

The 3386C-1-202LF is the appropriate selection for applications subject to RoHS3 or REACH compliance requirements. Both parts are active products from Bourns Inc. and are electrically and mechanically identical. Selection between these parts should be based solely on regulatory compliance obligations applicable to the end-use application and geographic market. The 3386C-1-202LF carries RoHS3 compliance and REACH-unaffected status, making it suitable for European Union markets and applications with mandatory RoHS requirements. The 3386C-1-202 remains available for applications without such regulatory constraints.

Frequently Asked Questions (FAQ)

Q: Can the 3386C-1-202LF be used as a direct replacement for the 3386C-1-202?

A: Yes. Both parts are electrically and mechanically identical with matching resistance, power rating, tolerance, temperature coefficient, adjustment type, resistive material, mounting configuration, and physical dimensions. The difference is regulatory compliance status only.

Q: What is the primary reason to substitute the 3386C-1-202 with the 3386C-1-202LF?

A: RoHS3 compliance and REACH regulatory status. The 3386C-1-202LF is RoHS3 compliant and REACH-unaffected, whereas the 3386C-1-202 is RoHS non-compliant and REACH-affected. Selection depends on application regulatory requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical square form factors measuring 0.375" x 0.375" (9.53mm x 9.53mm) with PC pin through-hole termination, ensuring identical PCB footprint compatibility.

Q: Do these parts have the same electrical performance specifications?

A: Yes. Both parts maintain identical 2 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, and 1-turn side adjustment with cermet resistive material.

Q: What packaging format is used for both parts?

A: Both the 3386C-1-202 and 3386C-1-202LF are supplied in tube packaging.
