Bourns 3386P-1-101T Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The Bourns 3386P-1-101T is a 100 Ohm, 0.5W through-hole trimmer potentiometer from the Trimpot® 3386 sealed series. This component is an active product designed for PC pin termination applications requiring precision resistance adjustment. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter set for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386P-1-101T is determined by strict equivalence across the following parameters:

• Resistance value: 100 Ohms
• 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

The Vishay Spectrol M63M101KB30T607 meets all electrical equivalence criteria. Mechanical differences (adjustment type and face dimension variance) do not preclude substitution when PCB layout and adjustment accessibility requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both components are active products with equivalent electrical specifications. The Vishay Spectrol M63M101KB30T607 offers ROHS3 compliance and MSL Level 1 rating, providing advantages for applications subject to RoHS directives and moisture-sensitive environments. The Bourns 3386P-1-101T remains suitable for applications without RoHS compliance requirements. Selection between these parts depends on regulatory compliance mandates and PCB layout constraints related to adjustment accessibility (top finger versus side adjustment) and the 0.02" (0.5mm) increase in face dimension for the Vishay part.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Spectrol M63M101KB30T607 directly replace the Bourns 3386P-1-101T?

A: Electrical substitution is valid when resistance, power rating, tolerance, temperature coefficient, number of turns, resistive material, mounting type, and termination style are identical. The Vishay part meets all these criteria. Physical layout verification is required due to adjustment type difference (side versus top) and a 0.02" increase in face dimension.

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

A: The 3386P-1-101T uses top finger adjustment, while the M63M101KB30T607 uses side adjustment. This affects PCB layout space requirements and accessibility for tuning operations. Confirm that your PCB design accommodates the side adjustment mechanism before substitution.

Q: Does the face dimension difference affect electrical performance?

A: No. The 0.02" (0.5mm) increase in face dimension (from 9.53mm to 10.03mm) is a mechanical characteristic only and does not alter electrical performance. PCB footprint clearance must be verified.

Q: What is the advantage of ROHS3 compliance in the Vishay part?

A: ROHS3 compliance indicates conformance to Restriction of Hazardous Substances directives. If your application or end market requires RoHS certification, the Vishay Spectrol M63M101KB30T607 is the appropriate selection.

Q: Are both parts suitable for high-temperature applications?

A: Both parts share an identical temperature coefficient of ±100ppm/°C. Temperature performance is equivalent between the two components.
