Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical 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 are grouped into two categories:

Direct Equivalent (Same Manufacturer): 3266W-1-102LF is a Bourns part within the same Trimpot® 3266 series, differing only in RoHS compliance status (ROHS3 Compliant versus non-compliant).

Cross-Manufacturer Equivalents (Functional Compatibility): 64WR1KLF and 64YR1KLF are TT Electronics/BI series 64 trimmer potentiometers that match all critical electrical and mechanical parameters. Minor dimensional variation exists (0.165" versus 0.170" face height), which remains within acceptable tolerance for standard through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliance Requirements: Select 3266W-1-102LF. This part maintains identical electrical and mechanical specifications to the main part while providing ROHS3 compliance certification. It is the preferred choice for applications subject to RoHS directives.

For REACH Compliance Requirements: Select 64WR1KLF or 64YR1KLF. Both TT Electronics/BI parts carry REACH Unaffected status, eliminating REACH compliance concerns. These parts are suitable for applications with strict REACH requirements.

For Standard Applications Without Compliance Constraints: All four parts are functionally equivalent. Selection may be based on inventory availability, lead time, or cost considerations. The 3266W-1-102LF offers the highest inventory level (30100 pcs).

For Space-Constrained PCB Layouts: The 3266W-1-102 and 3266W-1-102LF maintain the original 0.170" face height. The 64WR1KLF and 64YR1KLF have a 0.165" face height, providing a marginal reduction in vertical footprint.

Frequently Asked Questions (FAQ)

Q: Can 3266W-1-102LF be used as a direct replacement for 3266W-1-102?

A: Yes. Both parts are identical in electrical performance, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, termination style, and face dimensions. The only difference is RoHS compliance status. 3266W-1-102LF is ROHS3 compliant while 3266W-1-102 is non-compliant.

Q: Are the TT Electronics/BI parts (64WR1KLF and 64YR1KLF) electrically equivalent to the Bourns 3266W-1-102?

A: Yes. All critical electrical parameters match: 1 kOhm resistance, 0.25W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 12-turn adjustment, cermet material, and PC pin termination. The parts are functionally interchangeable in standard through-hole applications.

Q: What is the dimensional difference between the Bourns and TT Electronics/BI parts?

A: The Bourns 3266W-1-102 and 3266W-1-102LF have a face dimension of 0.250" x 0.170". The TT Electronics/BI 64WR1KLF and 64YR1KLF have a face dimension of 0.250" x 0.165". The height difference is 0.005" (0.127mm), which is negligible for most PCB applications.

Q: Which substitute part should be selected for new designs?

A: For new designs, 3266W-1-102LF is recommended as the primary choice due to ROHS3 compliance and high inventory availability. For applications requiring REACH compliance, 64WR1KLF or 64YR1KLF are appropriate alternatives.

Q: Are there any compliance or certification differences between these parts?

A: Yes. The 3266W-1-102 is RoHS non-compliant and REACH Affected. The 3266W-1-102LF is ROHS3 Compliant and REACH Affected. The 64WR1KLF and 64YR1KLF are RoHS Compliant and REACH Unaffected. All parts share the same ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the PCB layout accommodates the minor dimensional variation (0.005" height difference for TT Electronics/BI parts). All parts use identical PC pin termination and through-hole mounting, ensuring mechanical compatibility with standard PCB footprints.
