Bourns 3266Z-1-102 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The Bourns 3266Z-1-102 is a 1 kOhm, 0.25W through-hole trimmer potentiometer with PC pin termination and side adjustment capability. This sealed Trimpot® 3266 series component is designed for precision adjustment applications requiring cermet resistive elements and 12-turn resolution. The part is currently active in production with 815 units in stock. Substitute parts may be required due to supply constraints, regional availability, or specific compliance requirements for end applications.

Key Parameters

Substitute Part Grouping Explanation

The TT Electronics/BI 64PR1KLF qualifies as a direct electrical substitute for the Bourns 3266Z-1-102 based on the following critical parameters:

• Identical resistance value: 1 kOhms
• Matching power rating: 0.25W (1/4W)
• Equivalent tolerance: ±10%
• Identical temperature coefficient: ±100ppm/°C
• Same number of turns: 12
• Matching adjustment type: Side Adjustment
• Identical resistive material: Cermet
• Same mounting type: Through Hole
• Matching termination style: PC Pins

The primary difference is the face dimension (square 0.250" x 0.250" versus rectangular 0.250" x 0.170"), which may affect PCB layout compatibility. This dimensional variance requires verification against specific board space constraints before substitution.

Parameter Comparison

Engineering Selection Recommendations

The TT Electronics/BI 64PR1KLF presents a viable electrical substitute with superior compliance characteristics. The 64PR1KLF is RoHS Compliant and REACH Unaffected, whereas the Bourns 3266Z-1-102 is RoHS non-compliant and REACH Affected. For applications subject to RoHS or REACH regulatory requirements, the 64PR1KLF is the appropriate selection.

Both parts share identical electrical specifications and are suitable for equivalent functional performance. The dimensional difference (square versus rectangular face) is the primary consideration for mechanical compatibility. PCB layout verification is necessary to confirm that the larger square footprint of the 64PR1KLF does not conflict with existing board design constraints.

The 64PR1KLF offers higher inventory availability (2038 units versus 815 units), which may provide supply chain advantages for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can the TT Electronics/BI 64PR1KLF be used as a direct replacement for the Bourns 3266Z-1-102?

A: Yes, from an electrical standpoint. Both parts have identical resistance, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, and termination style. The primary consideration is the face dimension difference: the 64PR1KLF has a square 0.250" x 0.250" footprint compared to the rectangular 0.250" x 0.170" footprint of the 3266Z-1-102. PCB layout compatibility must be confirmed before substitution.

Q: What are the compliance differences between these two parts?

A: The Bourns 3266Z-1-102 is RoHS non-compliant and REACH Affected. The TT Electronics/BI 64PR1KLF is RoHS Compliant and REACH Unaffected. For applications requiring RoHS or REACH compliance, the 64PR1KLF is the appropriate choice.

Q: Are there any differences in moisture sensitivity?

A: The Bourns 3266Z-1-102 has no applicable moisture sensitivity level (MSL). The TT Electronics/BI 64PR1KLF is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For RoHS or REACH-compliant applications, use the 64PR1KLF. For applications with strict PCB space constraints requiring the smaller rectangular footprint, use the 3266Z-1-102. Both parts are active and in production.

Q: Is the difference in face dimensions critical?

A: The face dimension difference is a mechanical consideration only. The rectangular 3266Z-1-102 (0.250" x 0.170") occupies less board space than the square 64PR1KLF (0.250" x 0.250"). Verify that the larger footprint of the 64PR1KLF does not conflict with adjacent components or design constraints before substitution.
