Key Parameters

Substitute Part Grouping Explanation

The 3306F-1-201 qualifies as a functional substitute for the TC86F-1-201 based on the following critical 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)

Differing Parameters:

• Power rating: 0.2W (1/5W) versus 0.3W
• Tolerance: ±25% versus ±20%
• Physical dimensions: 0.319" x 0.268" (8.10mm x 6.80mm) versus 0.303" x 0.268" (7.70mm x 6.80mm)
• Product status: Active versus Obsolete

The 3306F-1-201 maintains electrical equivalence in resistance, temperature stability, and adjustment characteristics. The lower power rating and relaxed tolerance represent the primary technical differences requiring circuit-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

The 3306F-1-201 is suitable as a substitute for the obsolete TC86F-1-201 in applications where the following conditions are met:

1. Power Dissipation: Circuit design must accommodate the reduced power rating of 0.2W. Applications requiring sustained power dissipation above 0.2W require thermal analysis to confirm the 3306F-1-201 remains within safe operating limits.

2. Tolerance Requirements: The relaxed tolerance of ±25% on the 3306F-1-201 versus ±20% on the TC86F-1-201 must be acceptable for the circuit function. Applications with tight resistance tolerance specifications may require post-assembly calibration or selection.

3. Physical Fit: The 3306F-1-201 is marginally larger (0.319" versus 0.303" width). PCB layout and mechanical clearance must be verified to confirm the substitute fits within the allocated space.

4. Compliance: Both components maintain ROHS3 compliance and are unaffected by REACH regulations, ensuring regulatory continuity.

5. Availability: The 3306F-1-201 carries Active product status with established supply chain availability, providing long-term sourcing stability compared to the obsolete TC86F-1-201.

Frequently Asked Questions (FAQ)

Q: Can the 3306F-1-201 directly replace the TC86F-1-201 without circuit modification?

A: Direct replacement is possible if the circuit design operates within the 3306F-1-201 power rating of 0.2W and accepts the ±25% tolerance. If the original design relied on the 0.3W rating or ±20% tolerance, circuit evaluation is required.

Q: What is the impact of the lower power rating on component reliability?

A: The 0.2W rating establishes the maximum continuous power dissipation limit. Exceeding this limit results in excessive temperature rise and potential component failure. Calculate actual power dissipation in the application to confirm compliance.

Q: Are there physical installation concerns with the 3306F-1-201?

A: The 3306F-1-201 is 0.016" (0.4mm) wider than the TC86F-1-201. Verify PCB layout, component spacing, and mechanical clearances accommodate this dimensional difference.

Q: Do both components share identical electrical performance characteristics?

A: Both components maintain identical resistance value, temperature coefficient, and adjustment characteristics. The tolerance difference (±25% versus ±20%) represents the primary electrical specification variance.

Q: Is the 3306F-1-201 available for immediate procurement?

A: The 3306F-1-201 carries Active product status, indicating current manufacturing and established distribution channels. The TC86F-1-201 is obsolete and subject to limited availability.
