Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3266P-1-104 are identified based on electrical and mechanical parameter equivalence. The following parameters must match or be compatible for direct substitution:

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

The TT Electronics/BI 64XR100KLF meets all electrical specifications and mechanical compatibility requirements. Minor dimensional variation in the face width (0.165" vs 0.174") falls within acceptable tolerance for through-hole mounting applications and does not affect functional performance or PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Bourns 3266P-1-104 and TT Electronics/BI 64XR100KLF are active products suitable for new designs and production applications. The primary differentiation between these parts relates to regulatory compliance status:

The Bourns 3266P-1-104 is RoHS non-compliant and REACH Affected. The TT Electronics/BI 64XR100KLF is RoHS Compliant and REACH Unaffected, with MSL rating of 1 (Unlimited).

For applications requiring RoHS compliance or REACH compliance, the TT Electronics/BI 64XR100KLF is the appropriate selection. For legacy systems or applications without regulatory constraints, either part is functionally equivalent. The minor dimensional difference (0.009" width variation) does not impact PCB layout or mechanical fit for standard through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the TT Electronics/BI 64XR100KLF be used as a direct replacement for the Bourns 3266P-1-104?

A: Yes. All electrical parameters (resistance, power rating, tolerance, temperature coefficient, number of turns) and mechanical specifications (adjustment type, mounting type, termination style) are identical. The face width difference of 0.009" is within acceptable tolerance for through-hole PCB mounting and does not affect functional performance or circuit operation.

Q: What is the primary reason to substitute the Bourns 3266P-1-104 with the TT Electronics/BI 64XR100KLF?

A: The TT Electronics/BI 64XR100KLF offers RoHS compliance and REACH compliance status, making it suitable for applications subject to these regulatory requirements. The Bourns part does not meet these standards.

Q: Are there any dimensional concerns when substituting these parts?

A: The face dimensions differ slightly: Bourns 3266P-1-104 is 0.250" x 0.174", while the TT Electronics/BI 64XR100KLF is 0.250" x 0.165". This 0.009" width reduction is within standard manufacturing tolerance and does not affect through-hole mounting compatibility or PCB layout.

Q: Do both parts use the same resistive material and adjustment mechanism?

A: Yes. Both parts use Cermet resistive material and side adjustment mechanism, ensuring identical performance characteristics and adjustment feel.

Q: What is the inventory status for these parts?

A: The Bourns 3266P-1-104 has 742 pieces in stock. The TT Electronics/BI 64XR100KLF has 2824 pieces in stock, providing greater availability for procurement.
