Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC86W-1-103 is determined by the following critical parameters:

• Resistance value: 10 kOhms (exact match required)
• Adjustment type: Side Adjustment (functional requirement)
• Mounting type: Through Hole with PC Pins (mechanical compatibility)
• Resistive material: Cermet (performance characteristic)
• Number of turns: 1 (operational specification)
• Temperature coefficient: ±250ppm/°C (thermal stability)

The 3306W-1-103 qualifies as a substitute based on matching all core functional and mechanical parameters. While the power rating differs (0.2W versus 0.3W) and tolerance is wider (±25% versus ±20%), these variations remain within acceptable substitution criteria for this component category.

Parameter Comparison

Engineering Selection Recommendations

The 3306W-1-103 is the designated substitute for the obsolete TC86W-1-103. Both components maintain identical compliance certifications (ROHS3, REACH Unaffected) and moisture sensitivity ratings (MSL 1). The substitute is manufactured by the same supplier (Bourns Inc.) and belongs to the same Trimpot® product family, ensuring design continuity.

The 3306W-1-103 carries active product status, providing long-term availability and supply chain stability compared to the obsolete TC86W-1-103. Physical dimensions differ slightly, requiring verification of PCB layout compatibility. The reduced power rating (0.2W versus 0.3W) necessitates circuit analysis to confirm thermal performance remains acceptable for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the 3306W-1-103 be used as a direct replacement for the TC86W-1-103?

A: The 3306W-1-103 is functionally compatible based on matching resistance, adjustment type, mounting configuration, and resistive material. Physical dimensions differ slightly (0.268" x 0.319" versus 0.303" x 0.268"), requiring PCB layout verification. The lower power rating (0.2W versus 0.3W) must be evaluated against circuit power dissipation requirements.

Q: What are the key differences between these two parts?

A: Primary differences include power rating (0.3W versus 0.2W), tolerance specification (±20% versus ±25%), physical dimensions, and product status (obsolete versus active). Functional parameters including resistance value, temperature coefficient, adjustment type, and mounting configuration remain identical.

Q: Is the 3306W-1-103 available in the same packaging as the TC86W-1-103?

A: The TC86W-1-103 is supplied in standard packaging, while the 3306W-1-103 is available in bulk packaging. Both utilize identical termination styles (PC Pins) and mounting methods (through-hole).

Q: Are both parts RoHS compliant?

A: Yes, both the TC86W-1-103 and 3306W-1-103 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
