Key Parameters

Substitute Part Grouping Explanation

The 3306P-1-102 qualifies as a substitute for the TC86P-1-102 based on the following alignment of critical parameters:

• Resistance value: Both rated at 1 kOhms
• Temperature coefficient: Both specified at ±250ppm/°C
• Number of turns: Both single-turn designs
• Adjustment type: Both feature top adjustment
• Resistive material: Both utilize cermet construction
• Mounting type: Both are through-hole components
• Termination style: Both employ PC pins
• RoHS compliance: Both ROHS3 compliant
• Moisture sensitivity: Both MSL 1 (Unlimited)

The primary differences are power rating (0.3W vs. 0.2W), tolerance (±20% vs. ±25%), physical dimensions (7.70mm x 6.80mm vs. 8.10mm x 6.80mm), and product status (obsolete vs. active). These differences must be evaluated within the context of the specific application circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The 3306P-1-102 is available as an active product with established supply chain presence, whereas the TC86P-1-102 is obsolete. Both components meet ROHS3 compliance and carry identical moisture sensitivity ratings, ensuring regulatory and environmental consistency.

When evaluating substitution feasibility, consider the following provided specifications:

• Power dissipation requirements: The TC86P-1-102 is rated for 0.3W while the 3306P-1-102 is rated for 0.2W. Applications requiring power dissipation above 0.2W may exceed the substitute's thermal capability.
• Tolerance requirements: The TC86P-1-102 specifies ±20% tolerance versus ±25% for the 3306P-1-102. Circuits with tight tolerance requirements may be affected by the wider tolerance band of the substitute.
• Physical space constraints: The 3306P-1-102 has a slightly larger face dimension (8.10mm vs. 7.70mm width). PCB layout compatibility must be verified.

Both components share identical temperature coefficient, resistive material, termination style, and mounting methodology, supporting functional equivalence in applications where power and tolerance margins permit.

Frequently Asked Questions (FAQ)

Q: Can the 3306P-1-102 directly replace the TC86P-1-102 in all applications?

A: Direct substitution depends on application-specific requirements. Both components share identical resistance, temperature coefficient, adjustment type, and termination style. However, the lower power rating (0.2W vs. 0.3W) and wider tolerance (±25% vs. ±20%) of the 3306P-1-102 must be verified against circuit specifications before implementation.

Q: What is the significance of the power rating difference?

A: Power rating indicates maximum continuous power dissipation. If the circuit design requires dissipation above 0.2W, the 3306P-1-102 may operate outside its rated specification. Circuit analysis is required to determine actual power dissipation at the trimmer potentiometer.

Q: Are there physical mounting considerations?

A: The 3306P-1-102 has a width of 8.10mm compared to 7.70mm for the TC86P-1-102. Both share identical height (6.80mm) and employ PC pin through-hole termination. PCB layout must accommodate the slightly larger width dimension.

Q: Do both components meet the same compliance standards?

A: Yes. Both the TC86P-1-102 and 3306P-1-102 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Why is the TC86P-1-102 listed as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. The 3306P-1-102, as an active product within the same Trimpot® family, represents the current production alternative for equivalent 1 kOhms trimmer potentiometer applications.
