Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3266Y-1-101RLF is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 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 64WR100LF from TT Electronics/BI meets all electrical and mechanical criteria for direct substitution. Minor dimensional variation in the face width (0.165" vs. 0.170") remains within acceptable mechanical tolerance for through-hole PCB mounting applications. Packaging format differs (Tube vs. Tape & Reel), which affects procurement and handling but does not impact functional performance.

Parameter Comparison

Engineering Selection Recommendations

The 64WR100LF qualifies as a direct functional equivalent to the 3266Y-1-101RLF based on complete electrical parameter alignment and mechanical compatibility. Both components maintain active product status and comply with applicable regulatory frameworks (RoHS, ECCN EAR99, HTSUS classification). The 64WR100LF carries RoHS compliance designation and REACH unaffected status, while the original part is RoHS3 compliant and REACH affected. Selection between these parts should be based on procurement availability, packaging requirements (Tube vs. Tape & Reel), and supply chain considerations rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can the 64WR100LF replace the 3266Y-1-101RLF in existing designs?

A: Yes. All critical electrical parameters (resistance, power rating, tolerance, temperature coefficient, turn count) and mechanical specifications (through-hole mounting, PC pin termination, top adjustment) are equivalent. The 0.005" difference in face width (0.165" vs. 0.170") does not affect PCB hole alignment or functional performance.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel packaging is used for automated assembly processes and high-volume production. Tube packaging is used for manual assembly or lower-volume applications. Both formats contain identical components; packaging selection depends on manufacturing process requirements, not component performance.

Q: Are there compliance differences between these parts?

A: Both parts comply with EAR99 export classification and HTSUS code 8533.40.8050. The 3266Y-1-101RLF carries RoHS3 and REACH affected designations, while the 64WR100LF carries RoHS and REACH unaffected designations. Compliance requirements should be verified against specific application and regional regulations.

Q: What does the ±100ppm/°C temperature coefficient mean for substitution?

A: This specification indicates the resistance change per degree Celsius across the operating temperature range. Both parts share identical temperature coefficient performance, ensuring equivalent stability and accuracy in temperature-sensitive applications.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that packaging format (Tube vs. Tape & Reel) aligns with assembly equipment capabilities. No design modifications or PCB layout changes are required for substitution.
