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

Part Overview

The Bourns 3386U-1-105TLF is a 1 MOhm, 0.5W through-hole trimmer potentiometer with cermet resistive material, designed for PC pin termination and top finger adjustment. This component is part of the Trimpot® 3386 sealed series and maintains active product status. Equivalent and substitute parts may be required due to inventory availability, lead time considerations, or specific application requirements where alternative adjustment mechanisms or packaging formats are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 3386U-1-105TLF is permissible when the following core electrical and mechanical parameters remain constant:

• Resistance value: 1 MOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• RoHS compliance: ROHS3 Compliant

Variations in adjustment type (top finger versus side adjustment) and face dimensions within acceptable mechanical tolerances do not prevent functional substitution, provided the component fits within the available PCB space and adjustment accessibility requirements of the application.

Parameter Comparison

Engineering Selection Recommendations

Both the Bourns 3386U-1-105TLF and Vishay Spectrol M63M105KB30T607 meet identical electrical specifications and regulatory compliance requirements. Selection between these components should be based on:

1. Physical space constraints: The Vishay Spectrol component has a slightly larger face dimension (10.03mm versus 9.53mm). Verify PCB layout accommodates the larger footprint.

2. Adjustment accessibility: The Bourns component features top finger adjustment, while the Vishay Spectrol component features side adjustment. Confirm the application design permits the required adjustment orientation.

3. Inventory and lead time: Both components maintain active product status with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications.

Frequently Asked Questions (FAQ)

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

A: Yes, provided the application accommodates the side adjustment mechanism and the slightly larger face dimension (10.03mm versus 9.53mm). All electrical parameters, power rating, tolerance, and temperature coefficient are identical.

Q: What is the significance of the adjustment type difference?

A: The Bourns component uses top finger adjustment, accessed from above the PCB. The Vishay Spectrol component uses side adjustment, accessed from the side. The choice depends on PCB layout and accessibility requirements during calibration or field adjustment.

Q: Are both components RoHS compliant?

A: Yes. Both the Bourns 3386U-1-105TLF and Vishay Spectrol M63M105KB30T607 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What packaging formats are available?

A: The Bourns 3386U-1-105TLF is supplied in tube packaging. The Vishay Spectrol M63M105KB30T607 is supplied in box packaging. Confirm packaging requirements with procurement or supply chain specifications.

Q: Are there any electrical performance differences between these components?

A: No. Both components share identical resistance (1 MOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), and cermet resistive material. Electrical performance is equivalent.
