Parameter Comparison

Engineering Selection Recommendations

Both the 3386W-1-102ALF and 72XR1KLF maintain Active product status and ROHS3 compliance. Selection between these parts may be based on availability, packaging format (Tape & Box versus Bulk), or supply chain requirements. The 72XR1KLF is available in higher inventory quantity (2606 pcs versus 1107 pcs). Both components satisfy identical electrical performance and mechanical interface requirements for through-hole PCB assembly applications.

Frequently Asked Questions (FAQ)

Q: Can the 72XR1KLF replace the 3386W-1-102ALF in existing designs?

A: Yes. Both parts share identical electrical specifications (1 kOhm, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient) and mechanical compatibility (through-hole mounting, PC pin termination, 0.375" x 0.375" footprint, side adjustment).

Q: What is the difference between the two part numbers?

A: The primary differences are manufacturer (Bourns versus TT Electronics/BI), series designation (Trimpot® 3386 versus 72), and packaging format (Tape & Box versus Bulk). Electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. No compliance differences exist between the two parts.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Box or Bulk) does not affect component performance. Selection is based on assembly process requirements and inventory management.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Identical footprint, pin configuration, and electrical characteristics enable direct substitution without PCB redesign or assembly process modification.
