Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3266Y-1-102 is determined by strict equivalence across the following parameters: resistance value (1 kOhms), power rating (0.25W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (12), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins).

The substitute parts 64WR1KLF and 64YR1KLF from TT Electronics/BI meet all electrical and mechanical requirements for direct substitution. Both parts maintain identical resistance, power rating, tolerance, temperature coefficient, and turn count. Physical dimensions are within acceptable tolerance (0.250" x 0.165" versus 0.250" x 0.170"), representing a 0.03mm reduction in height that does not affect PCB layout or functional performance.

Parameter Comparison

Engineering Selection Recommendations

Both 64WR1KLF and 64YR1KLF are functionally equivalent to the 3266Y-1-102 based on electrical and mechanical parameters. The TT Electronics/BI substitutes offer improved compliance status: both are RoHS compliant and REACH unaffected, compared to the Bourns part which is RoHS non-compliant and REACH affected. Selection between the two TT Electronics/BI options should be based on supply availability and inventory requirements, as they are electrically and mechanically identical.

Frequently Asked Questions (FAQ)

Q: Can 64WR1KLF and 64YR1KLF be used interchangeably with 3266Y-1-102?

A: Yes. Both substitute parts meet all specified electrical parameters (1 kOhms, 0.25W, ±10% tolerance, ±100ppm/°C temperature coefficient, 12 turns) and mechanical requirements (top adjustment, cermet material, through-hole mounting, PC pin termination). The minor dimensional difference (0.165" versus 0.170" height) does not affect PCB layout or performance.

Q: What is the primary difference between the substitute parts and the original?

A: The substitute parts from TT Electronics/BI are RoHS compliant and REACH unaffected, whereas the Bourns 3266Y-1-102 is RoHS non-compliant and REACH affected. All other electrical and mechanical specifications are equivalent.

Q: Are there any compatibility concerns with PCB layout?

A: No. The 0.03mm reduction in face height (from 4.32mm to 4.19mm) is within standard PCB tolerance and does not affect component placement, soldering, or functional performance.

Q: How do I choose between 64WR1KLF and 64YR1KLF?

A: Both parts are electrically and mechanically identical. Selection should be based on supply chain availability and inventory management requirements.
