Bourns 3386Y-1-105TLF Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The Bourns 3386Y-1-105TLF is a 1 MOhm, 0.5W through-hole trimmer potentiometer with cermet resistive material and top finger adjustment. This component is classified as Active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications, mechanical mounting compatibility, and regulatory certifications align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386Y-1-105TLF is determined by the following critical parameters:

• Electrical Match: Resistance value (1 MOhms), power rating (0.5W), tolerance (±10%), and temperature coefficient (±100ppm/°C) must be identical
• Material Composition: Cermet resistive material required for thermal stability and performance characteristics
• Mechanical Compatibility: Through-hole mounting with PC pin termination style
• Regulatory Compliance: RoHS3 compliance mandatory for equivalent substitution
• Functional Turns: Single-turn (1.0 Turn) adjustment mechanism

The Vishay Spectrol M63M105KB30T607 meets all electrical and material specifications. The primary design difference is adjustment type (side adjustment versus top finger adjustment) and minor dimensional variation (0.395" vs 0.375" face dimension).

Parameter Comparison

Engineering Selection Recommendations

Both components maintain Active product status and full regulatory compliance under RoHS3 and REACH standards. Electrical performance parameters are identical across resistance, power dissipation, tolerance, and temperature coefficient specifications. The Vishay Spectrol M63M105KB30T607 is electrically and functionally equivalent for applications requiring 1 MOhm, 0.5W cermet trimmer potentiometers with through-hole PC pin termination.

Design consideration: The adjustment mechanism differs between the two parts (top finger versus side adjustment). PCB layout and mechanical access requirements should be evaluated to confirm compatibility with the intended application. The Vishay part has a marginally larger face dimension (0.395" versus 0.375"), which may affect board space allocation in compact designs.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Spectrol M63M105KB30T607 directly replace the Bourns 3386Y-1-105TLF?

A: Electrical substitution is valid. Both parts share identical resistance (1 MOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), and cermet material composition. Mechanical compatibility depends on PCB layout tolerance for the 0.02" (0.5mm) larger face dimension and adjustment mechanism accessibility (side adjustment versus top finger adjustment).

Q: Are there compliance or regulatory differences between these parts?

A: No. Both components are RoHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8533.40.8050) codes.

Q: What is the primary design difference between these two trimmer potentiometers?

A: The adjustment interface differs. The Bourns 3386Y uses top finger adjustment, while the Vishay Spectrol M63M105KB30T607 uses side adjustment. This affects operator access and PCB layout considerations but does not impact electrical performance.

Q: Do both parts use the same resistive material?

A: Yes. Both employ cermet resistive material, ensuring equivalent thermal stability, frequency response, and long-term reliability characteristics.

Q: Are packaging formats interchangeable?

A: Both parts use through-hole PC pin termination and are suitable for wave soldering and manual assembly. Packaging format differs (Bourns supplied in Tube; Vishay in Box), but this does not affect component functionality or PCB integration.
