Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC86P-1-101 is based on the following critical parameters that must remain consistent or compatible:

• Resistance value: 100 Ohms (exact match required)
• Adjustment type: Top 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 3306P-1-101 qualifies as a substitute based on matching these core parameters. Variations in power rating (0.3W vs. 0.2W), tolerance (±20% vs. ±25%), and physical dimensions (7.70mm x 6.80mm vs. 8.10mm x 6.80mm) are within acceptable engineering tolerances for this component category, provided the application circuit design accommodates these differences.

Parameter Comparison

Engineering Selection Recommendations

The 3306P-1-101 is the primary substitute for the obsolete TC86P-1-101. Both components are manufactured by Bourns Inc. and maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification). The 3306P-1-101 carries active product status, ensuring continued availability and supply chain reliability.

Key considerations for substitution:

The 3306P-1-101 operates at a lower power rating (0.2W vs. 0.3W). Circuit designs must confirm that the application does not exceed 0.2W dissipation at the trimmer potentiometer. The slightly larger physical footprint (8.10mm vs. 7.70mm width) requires verification of PCB layout compatibility. The increased tolerance specification (±25% vs. ±20%) may impact circuit calibration precision in applications requiring tighter resistance accuracy.

Both components share identical temperature coefficient performance and MSL ratings, ensuring equivalent thermal and moisture handling characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 3306P-1-101 be used as a direct replacement for the TC86P-1-101?

A: The 3306P-1-101 is functionally compatible as a substitute provided the application circuit operates within the 0.2W power dissipation limit and accommodates the 0.4mm increase in component width. Both components feature identical resistance, adjustment type, mounting configuration, and thermal characteristics.

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

A: The lower power rating of the 3306P-1-101 requires circuit analysis to confirm that trimmer potentiometer dissipation does not exceed 0.2W during normal operation. Applications designed for the TC86P-1-101 with higher dissipation margins must be re-evaluated.

Q: Does the tolerance difference (±20% vs. ±25%) affect circuit performance?

A: The 3306P-1-101 tolerance of ±25% is wider than the TC86P-1-101 specification of ±20%. Applications requiring precise resistance calibration must account for this increased tolerance band during design validation and production testing.

Q: Are there physical mounting differences between these components?

A: Both components use identical through-hole PC pin termination and top adjustment configuration. The 3306P-1-101 is 0.4mm wider (8.10mm vs. 7.70mm). PCB layout must be verified to accommodate this dimensional difference.

Q: What is the supply status of each component?

A: The TC86P-1-101 is obsolete with limited remaining inventory. The 3306P-1-101 is active production with established supply availability, making it the recommended choice for new designs and ongoing production support.
