TC86W-1-101 Equivalent & Substitute Parts

Part Overview

The TC86W-1-101 is a 100 Ohm, 0.3W through-hole trimmer potentiometer manufactured by Bourns Inc. as part of the Trimpot® TC86 series. This component features cermet resistive material, side adjustment capability, and PC pin termination for through-hole mounting applications. The TC86W-1-101 is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC86W-1-101 is determined by the following critical parameters:

• Resistance Value: 100 Ohms (exact match required)
• Adjustment Type: Side Adjustment (functional requirement)
• Mounting Type: Through Hole with PC Pins (mechanical compatibility)
• Resistive Material: Cermet (performance characteristic)
• Temperature Coefficient: ±250ppm/°C (thermal stability requirement)
• Number of Turns: 1 (adjustment range specification)

The 3306W-1-101 meets these core substitution criteria. Variations in power rating (0.3W vs. 0.2W), tolerance (±20% vs. ±25%), and physical dimensions represent acceptable trade-offs within the allowed parameter range for this product category, provided circuit design accommodates the lower power specification.

Parameter Comparison

Engineering Selection Recommendations

The 3306W-1-101 is the primary substitute for the obsolete TC86W-1-101. Both components are manufactured by Bourns Inc. and maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification). The 3306W-1-101 carries active product status, ensuring continued availability and supply chain support.

The 3306W-1-101 is suitable for applications where the TC86W-1-101 was previously specified, subject to the following circuit-level considerations:

• Power dissipation in the application must not exceed 0.2W continuous operation
• Tolerance variation (±25% vs. ±20%) must be acceptable for the circuit function
• Physical dimensions differ slightly; PCB layout verification is required to confirm mechanical fit within the allocated space

Frequently Asked Questions (FAQ)

Q: Can the 3306W-1-101 directly replace the TC86W-1-101 in existing designs?

A: The 3306W-1-101 is electrically and mechanically compatible for through-hole PCB mounting. The primary design consideration is power dissipation; if the circuit operates the trimmer potentiometer below 0.2W, substitution is valid. Physical dimensions differ slightly, requiring PCB layout verification.

Q: What is the significance of the power rating difference (0.3W vs. 0.2W)?

A: Power rating indicates maximum continuous power dissipation. The 3306W-1-101 at 0.2W is suitable for lower-power applications. If the original design requires sustained operation above 0.2W, the 3306W-1-101 is not appropriate.

Q: Are tolerance differences (±20% vs. ±25%) critical for substitution?

A: Tolerance differences depend on circuit requirements. If the original design accommodates ±20% tolerance, the wider ±25% tolerance of the 3306W-1-101 may be acceptable. Circuit analysis is required to confirm functional performance.

Q: Why is the TC86W-1-101 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 3306W-1-101, with active product status, represents the current equivalent offering from Bourns Inc. for this resistance and power class.

Q: Are both components RoHS compliant?

A: Yes. Both the TC86W-1-101 and 3306W-1-101 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
