Bourns 3266P-1-102 Trimmer Potentiometer: Equivalent & Substitute Parts

Part Overview

The Bourns 3266P-1-102 is a 1 kOhm, 0.25W through-hole trimmer potentiometer with PC pin termination and side adjustment. It belongs to the Trimpot® 3266 sealed series and maintains active product status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the core functional parameters: resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, and termination style.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching all core electrical and mechanical parameters. The following criteria must align for a part to function as a direct equivalent:

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

Both identified substitutes—3266X-1-102LF (Bourns Inc.) and 64PR1KLF (TT Electronics/BI)—satisfy all core parameter requirements. Variations in face dimensions and compliance certifications do not affect functional equivalence for standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and satisfy core electrical and mechanical requirements. Selection between them depends on regulatory and compliance requirements:

3266P-1-102 (Bourns Inc.): Original specification. RoHS non-compliant; REACH Affected. Use when legacy compliance status is acceptable or required by existing design documentation.

3266X-1-102LF (Bourns Inc.): RoHS3 Compliant; REACH Affected. Preferred for new designs requiring RoHS3 compliance while maintaining Bourns manufacturing continuity. Minimal dimensional variation (0.170" vs. 0.174" height) does not affect PCB layout compatibility for standard applications.

64PR1KLF (TT Electronics/BI): RoHS Compliant; REACH Unaffected. Suitable for applications requiring REACH compliance exemption. Larger square footprint (0.250" x 0.250") requires PCB layout verification to confirm clearance compatibility.

Frequently Asked Questions (FAQ)

Q: Can 3266X-1-102LF replace 3266P-1-102 in existing designs? A: Yes. Both parts share identical electrical specifications and core mechanical parameters. The 3266X-1-102LF has a slightly smaller height dimension (0.170" vs. 0.174"), which does not affect standard PCB layouts. Verify clearance if space constraints exist.

Q: What is the primary difference between 3266X-1-102LF and 64PR1KLF? A: Both are electrically equivalent. The 3266X-1-102LF is a Bourns product with RoHS3 compliance and REACH Affected status. The 64PR1KLF is manufactured by TT Electronics/BI with RoHS compliance and REACH Unaffected status. The 64PR1KLF has a larger square footprint (0.250" x 0.250" vs. 0.250" x 0.170"), requiring PCB layout confirmation.

Q: Are there compliance implications when switching between these parts? A: Yes. The 3266P-1-102 is RoHS non-compliant. The 3266X-1-102LF is RoHS3 Compliant but REACH Affected. The 64PR1KLF is RoHS Compliant and REACH Unaffected. Select based on your application's regulatory requirements.

Q: Do dimensional differences affect circuit performance? A: No. All three parts are functionally equivalent. Dimensional variations affect only PCB layout and mechanical fit. Verify available board space before selecting 64PR1KLF due to its larger square footprint.

Q: Can these parts be used interchangeably in production? A: Yes, provided PCB layout accommodates the selected part's footprint and your design meets the corresponding compliance requirements. Confirm with your quality and regulatory teams before implementing substitutions in production.
