Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 3386B-1-102 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Square - 0.375" x 0.375" (9.53mm x 9.53mm)

The TT Electronics/BI 72XR1KLF meets all electrical and mechanical parameters required for direct substitution. Differences in packaging format and compliance certifications do not affect functional compatibility in applications where the core electrical and mechanical specifications are the controlling factors.

Parameter Comparison

Engineering Selection Recommendations

The TT Electronics/BI 72XR1KLF is a direct functional equivalent to the Bourns 3386B-1-102 based on complete electrical and mechanical parameter alignment. Selection between these parts should be based on:

• Packaging requirements: The Bourns part is supplied in tube packaging; the TT Electronics/BI part is supplied in bulk packaging.
• Regulatory compliance: The TT Electronics/BI 72XR1KLF is ROHS3 compliant and REACH unaffected, whereas the Bourns 3386B-1-102 is RoHS non-compliant and REACH affected. Applications subject to RoHS3 or REACH restrictions must use the TT Electronics/BI substitute.
• Inventory availability: The TT Electronics/BI part has higher stock availability (2606 pcs vs. 954 pcs).

Both parts carry the same ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Frequently Asked Questions (FAQ)

Q: Can the TT Electronics/BI 72XR1KLF be used as a direct replacement for the Bourns 3386B-1-102?

A: Yes. All electrical parameters (resistance, power rating, tolerance, temperature coefficient, number of turns) and mechanical parameters (mounting type, termination style, physical dimensions, adjustment type) are identical. The parts are functionally interchangeable.

Q: What is the difference in packaging between these parts?

A: The Bourns 3386B-1-102 is supplied in tube packaging, while the TT Electronics/BI 72XR1KLF is supplied in bulk packaging. Tube packaging is typically used for smaller order quantities or applications requiring individual component handling. Bulk packaging is used for higher-volume applications.

Q: Which part should I select if my application requires RoHS3 compliance?

A: The TT Electronics/BI 72XR1KLF is ROHS3 compliant. The Bourns 3386B-1-102 is RoHS non-compliant and cannot be used in applications with RoHS3 requirements.

Q: Are there any differences in electrical performance between these parts?

A: No. Both parts have identical resistance values, power ratings, tolerances, temperature coefficients, and number of turns. Electrical performance is equivalent.

Q: What is the physical footprint compatibility?

A: Both parts have identical square form factors of 0.375" x 0.375" (9.53mm x 9.53mm) with PC pin termination. They are mechanically interchangeable on PCBs designed for either part.

Q: Does REACH compliance affect my selection?

A: If your application or supply chain requires REACH compliance, the TT Electronics/BI 72XR1KLF is REACH unaffected and is the appropriate choice. The Bourns 3386B-1-102 is REACH affected.
