Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC86W-1-201 is based on the following critical parameters that must remain consistent or compatible:

• Resistance value: 200 Ohms (exact match required)
• Adjustment type: Side Adjustment (functional requirement)
• Resistive material: Cermet (performance characteristic)
• Mounting type: Through Hole with PC Pins (board integration requirement)
• Number of turns: 1 (operational specification)
• Temperature coefficient: ±250ppm/°C (thermal stability requirement)

The 3306W-1-201 meets these core substitution criteria. While the power rating differs (0.2W versus 0.3W), the 3306W-1-201 maintains all critical electrical and mechanical parameters necessary for functional equivalence in applications where the lower power rating is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The 3306W-1-201 is the primary substitute for the obsolete TC86W-1-201. Both components are manufactured by Bourns Inc. and maintain identical resistance, temperature coefficient, adjustment type, and resistive material specifications. The 3306W-1-201 is currently in active production status, ensuring long-term availability and supply chain continuity.

Key considerations for selection:

• Power rating: The 3306W-1-201 operates at 0.2W compared to the TC86W-1-201 at 0.3W. Substitution is appropriate for applications where the circuit dissipation does not exceed 0.2W.
• Tolerance: The 3306W-1-201 has ±25% tolerance versus ±20% for the original part. Applications requiring tighter tolerance control should evaluate this difference.
• Physical dimensions: The 3306W-1-201 has slightly different face dimensions (0.268" x 0.319" versus 0.303" x 0.268"). PCB layout verification is required to confirm fit within existing mounting footprints.
• Compliance: Both components maintain ROHS3 compliance and unlimited MSL rating, ensuring compatibility with modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3306W-1-201 directly replace the TC86W-1-201 in all applications?

A: The 3306W-1-201 is functionally equivalent for applications where the circuit power dissipation does not exceed 0.2W. If the original design requires the full 0.3W power rating, the 3306W-1-201 may not be suitable. PCB layout verification is also required due to dimensional differences.

Q: What is the significance of the tolerance difference between these parts?

A: The TC86W-1-201 has ±20% tolerance while the 3306W-1-201 has ±25% tolerance. For applications requiring precise resistance values, this difference should be evaluated against circuit performance requirements.

Q: Are there any compliance or environmental differences between these parts?

A: Both components are ROHS3 compliant and have MSL rating 1 (unlimited moisture sensitivity level). No compliance or environmental differences exist between the two parts.

Q: What are the physical mounting considerations?

A: The 3306W-1-201 has face dimensions of 0.268" x 0.319" (6.81mm x 8.10mm) compared to the TC86W-1-201 at 0.303" x 0.268" (7.70mm x 6.80mm). Both use through-hole PC pin termination. PCB footprint verification is necessary to confirm fit within existing mounting holes and clearance requirements.

Q: Why is the TC86W-1-201 obsolete?

A: The TC86W-1-201 is classified as obsolete by the manufacturer. The 3306W-1-201 from the active Trimpot® 3306 series provides equivalent functionality and is recommended for new designs and ongoing procurement.
