Parameter Comparison

Engineering Selection Recommendations

Both the Bourns 3266P-1-202 and TT Electronics/BI 64XR2KLF are active production components with identical electrical and functional specifications. Selection between these parts should be based on compliance requirements and regulatory status:

The TT Electronics/BI 64XR2KLF is RoHS Compliant and REACH Unaffected, making it suitable for applications subject to European Union environmental directives. The Bourns 3266P-1-202 is RoHS non-compliant and REACH Affected, which may restrict its use in certain regulated markets or end applications.

Physical dimensions differ slightly (0.174" vs 0.165" height), but both maintain the same 0.250" width and PC pin footprint, ensuring compatibility with standard through-hole PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the TT Electronics/BI 64XR2KLF directly replace the Bourns 3266P-1-202 in existing designs?

A: Yes. Both components share identical electrical specifications (2 kOhms, 0.25W, ±10% tolerance, ±100ppm/°C, 12-turn side adjustment, cermet resistive element, PC pin termination). Physical dimensions are compatible with standard through-hole PCB mounting.

Q: What is the primary difference between these two parts?

A: The main differences are compliance certifications. The TT Electronics/BI 64XR2KLF is RoHS Compliant and REACH Unaffected, while the Bourns 3266P-1-202 is RoHS non-compliant and REACH Affected. Physical height differs by 0.009" (0.23mm).

Q: Are there any functional performance differences?

A: No. Both components have identical resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, and resistive material. Functional performance in circuit operation is equivalent.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance or REACH compliance, use the TT Electronics/BI 64XR2KLF. For applications without these constraints, either part is functionally equivalent.

Q: Are the PC pin footprints identical?

A: Yes. Both components use PC pin termination with the same 0.250" width, ensuring compatibility with existing PCB layouts designed for either part number.
