Key Parameters

Substitute Part Grouping Explanation

The 3306P-1-201 qualifies as a functional substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Resistance value: 200 Ohms (identical)
• Temperature coefficient: ±250ppm/°C (identical)
• Number of turns: 1 (identical)
• Adjustment type: Top Adjustment (identical)
• Resistive material: Cermet (identical)
• Mounting type: Through Hole (identical)
• Termination style: PC Pins (identical)
• RoHS compliance: ROHS3 Compliant (identical)
• MSL rating: 1 (Unlimited) (identical)

Allowable Variations:

• Power rating: 0.3W (TC86P-1-201) vs. 0.2W (3306P-1-201) — The substitute has lower power dissipation capacity, suitable for applications not exceeding 0.2W
• Tolerance: ±20% (TC86P-1-201) vs. ±25% (3306P-1-201) — The substitute has wider tolerance
• Physical dimensions: Minor variation in face width (0.303" vs. 0.319") within acceptable PCB layout tolerances
• Product status: Obsolete (TC86P-1-201) vs. Active (3306P-1-201) — The substitute is currently in active production

Parameter Comparison

Engineering Selection Recommendations

The 3306P-1-201 is suitable as a substitute for the obsolete TC86P-1-201 in applications where the following conditions are met:

• Circuit design does not require power dissipation exceeding 0.2W at the trimmer potentiometer
• Application tolerance stack-up can accommodate ±25% resistance tolerance
• PCB layout can accept the 0.016" (0.4mm) increase in component width
• Both components maintain identical compliance certifications (ROHS3, MSL 1)

The 3306P-1-201 is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete TC86P-1-201.

Frequently Asked Questions (FAQ)

Q: Can the 3306P-1-201 directly replace the TC86P-1-201 in existing designs?

A: Direct replacement is possible if the application power requirement does not exceed 0.2W. The 0.016" width difference requires PCB layout verification. All other electrical and mechanical parameters are compatible.

Q: What is the impact of the wider tolerance (±25% vs. ±20%) on circuit performance?

A: The tolerance difference affects initial resistance accuracy. Applications requiring tighter tolerance control should evaluate circuit sensitivity to the additional ±5% tolerance band.

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

A: Both components are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings. No compliance differences exist.

Q: Why is the TC86P-1-201 obsolete?

A: The TC86P-1-201 is classified as obsolete by the manufacturer. The 3306P-1-201 from the active Trimpot® 3306 series provides equivalent functionality with ongoing production support.

Q: How should PCB layout be adjusted for the dimensional difference?

A: The 3306P-1-201 is 0.016" wider (8.10mm vs. 7.70mm). Verify that the component footprint and surrounding circuit elements accommodate this width increase without interference.
