Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3266Y-1-201RLF is determined by strict equivalence across the following critical parameters:

• Resistance value: 200 Ohms
• Power rating: 0.25W (1/4W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 12
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins

The substitute part 64WR200LF (TT Electronics/BI) meets all electrical and mechanical criteria for direct substitution. Minor dimensional variation in face width (0.165" vs. 0.170") remains within acceptable tolerance for through-hole PCB mounting applications. Packaging format differs (Tube vs. Tape & Reel) but does not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the 3266Y-1-201RLF and 64WR200LF maintain active product status with full regulatory compliance. The 3266Y-1-201RLF carries RoHS3 and REACH Affected designations, while the 64WR200LF is RoHS Compliant and REACH Unaffected. Selection between these parts should consider supply chain requirements and regulatory obligations specific to the end application. The 64WR200LF offers higher inventory availability (1939 pcs vs. 999 pcs) and REACH unaffected status, which may simplify compliance documentation for certain markets. The 3266Y-1-201RLF maintains the original Trimpot® 3266 sealed series specification with RoHS3 compliance for applications requiring the highest environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the 64WR200LF directly replace the 3266Y-1-201RLF in existing designs?

A: Yes. Both parts share identical electrical specifications (200 Ohms, 0.25W, ±10% tolerance, ±100ppm/°C, 12-turn cermet), adjustment type (top), mounting method (through-hole PC pins), and face dimensions within acceptable tolerance (0.250" x 0.165" vs. 0.250" x 0.170"). No circuit redesign is required.

Q: What is the significance of the packaging difference (Tape & Reel vs. Tube)?

A: Packaging format affects handling and assembly processes but does not impact electrical or mechanical performance. Tape & Reel packaging suits high-volume automated assembly, while Tube packaging is typical for lower-volume or manual assembly operations. Selection depends on production volume and assembly equipment compatibility.

Q: Are there compliance considerations when switching between these parts?

A: Both parts are RoHS compliant and carry EAR99 ECCN classification. The 3266Y-1-201RLF is REACH Affected while the 64WR200LF is REACH Unaffected. Applications subject to REACH regulations should verify that the substitute part meets specific regional requirements.

Q: How do the temperature coefficients compare?

A: Both parts specify ±100ppm/°C temperature coefficient, ensuring equivalent thermal stability across operating ranges.

Q: Is the 0.005" (0.127mm) face width difference significant?

A: No. This dimensional variation falls within standard PCB hole tolerance and mounting clearance specifications for through-hole components. Both parts are mechanically compatible with standard 0.100" pitch PCB layouts.
