Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC86W-1-102 is determined by the following critical parameters:

• Resistance value: 1 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-1-102 qualifies as a substitute based on matching all critical parameters. While the power rating differs (0.2W vs. 0.3W), the 3306W-1-102 operates within the same functional category and maintains electrical and mechanical compatibility for applications where the lower power rating is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The 3306W-1-102 is an active product from Bourns Inc. and represents the primary substitute for the obsolete TC86W-1-102. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility.

Selection of the 3306W-1-102 is appropriate for applications where the power dissipation requirement does not exceed 0.2W. The slightly higher tolerance (±25% vs. ±20%) should be evaluated against circuit design margins. Both components share identical temperature coefficient specifications and resistive material composition, supporting equivalent thermal and long-term stability performance.

Frequently Asked Questions (FAQ)

Q: Can the 3306W-1-102 directly replace the TC86W-1-102 in all applications?

A: Direct replacement is possible when the application power dissipation does not exceed 0.2W. The 3306W-1-102 has a lower power rating (0.2W vs. 0.3W) and slightly wider tolerance (±25% vs. ±20%). Circuit analysis is required to confirm these differences are acceptable for the specific application.

Q: Are there mechanical compatibility concerns between these two parts?

A: Both components use through-hole PC pin termination and side adjustment configuration. Physical dimensions differ slightly (TC86W-1-102: 7.70mm x 6.80mm; 3306W-1-102: 6.81mm x 8.10mm). PCB layout and mounting clearance should be verified before implementation.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the TC86W-1-102 and 3306W-1-102 are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8533.40.8050.

Q: What is the primary advantage of using the 3306W-1-102?

A: The 3306W-1-102 is an active product with current manufacturing and availability, whereas the TC86W-1-102 is obsolete. This ensures long-term supply chain reliability and support.

Q: How do the temperature coefficients compare?

A: Both components have identical temperature coefficients of ±250ppm/°C, ensuring equivalent thermal stability and drift characteristics across operating temperature ranges.
