Bourns 3262W-1-202 Trimmer Potentiometer: Equivalent & Substitute Parts

Part Overview

The Bourns 3262W-1-202 is a 2 kOhm, 0.25W through-hole trimmer potentiometer with PC pin termination and top adjustment. This sealed Trimpot® 3262 series component is designed for precision resistance adjustment in electronic circuits requiring cermet resistive elements and 12-turn adjustment capability. The part is currently active in production. Substitute parts may be required due to RoHS compliance needs, inventory availability, or design flexibility across compatible product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3262W-1-202 is determined by matching the following critical parameters: 2 kOhm resistance value, 0.25W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 12-turn adjustment, top adjustment type, cermet resistive material, through-hole mounting, PC pin termination, and rectangular form factor within acceptable dimensional variance.

The substitute parts identified maintain these core electrical and mechanical specifications. Dimensional variations between the main part (0.250" x 0.170" face) and substitute parts (0.250" x 0.165" face for TT Electronics/BI variants) represent minor tolerance differences within the rectangular package category and do not affect functional compatibility in standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

3262W-1-202LF (Bourns Inc.): Direct substitute within the Bourns Trimpot® 3262 series. Identical electrical specifications and form factor. Primary distinction is ROHS3 compliance status, making this part suitable for applications requiring RoHS certification. Select this part when RoHS compliance is mandatory and Bourns product line continuity is preferred.

64WR2KLF (TT Electronics/BI): Cross-manufacturer substitute from the TT Electronics 64 series. Maintains all critical electrical parameters and through-hole PC pin configuration. Dimensional variance of 0.005" in the Y-axis (0.165" vs 0.170") is within standard PCB layout tolerances. RoHS compliant. Highest inventory availability (9660 pcs) provides supply chain flexibility. Select this part when cross-manufacturer sourcing is acceptable and maximum stock availability is required.

64YR2KLF (TT Electronics/BI): Cross-manufacturer substitute from the TT Electronics 64 series. Electrically and mechanically equivalent to 64WR2KLF with identical dimensional specifications. RoHS compliant. Select this part as an alternative within the TT Electronics product line when 64WR2KLF is unavailable.

All substitute parts are active products with confirmed inventory. Selection should prioritize application compliance requirements (RoHS status) and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can 3262W-1-202LF be used as a direct replacement for 3262W-1-202?

A: Yes. Both parts are Bourns Trimpot® 3262 series components with identical electrical specifications (2 kOhm, 0.25W, ±10% tolerance, ±100ppm/°C), adjustment characteristics (12-turn top adjustment), and physical form factor (0.250" x 0.170" rectangular). The primary difference is RoHS3 compliance status of the LF variant.

Q: What is the dimensional difference between Bourns and TT Electronics variants?

A: The Bourns 3262W series has a face dimension of 0.250" x 0.170" (6.35mm x 4.32mm). The TT Electronics 64 series (64WR2KLF and 64YR2KLF) has a face dimension of 0.250" x 0.165" (6.35mm x 4.19mm). The 0.005" difference in the Y-axis is within standard PCB layout tolerances and does not affect functional compatibility in typical through-hole applications.

Q: Are the TT Electronics parts (64WR2KLF and 64YR2KLF) electrically equivalent?

A: Yes. Both TT Electronics parts maintain identical electrical specifications: 2 kOhm resistance, 0.25W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 12-turn adjustment, cermet resistive material, and top adjustment type. They differ only in series designation within the TT Electronics product line.

Q: Which substitute part should be selected for RoHS-compliant applications?

A: All three substitute parts (3262W-1-202LF, 64WR2KLF, and 64YR2KLF) are RoHS compliant. The 3262W-1-202LF maintains Bourns product line continuity, while 64WR2KLF and 64YR2KLF provide cross-manufacturer alternatives with equivalent compliance status.

Q: What is the inventory status of each part?

A: Current inventory levels are 3262W-1-202 (962 pcs), 3262W-1-202LF (1351 pcs), 64WR2KLF (9660 pcs), and 64YR2KLF (1733 pcs). The 64WR2KLF variant offers the highest stock availability.

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

A: Yes, provided the PCB layout accommodates the minor dimensional variance (0.005" difference in Y-axis for TT Electronics variants). All parts share identical electrical specifications, through-hole mounting type, PC pin termination, and rectangular form factor, making them functionally interchangeable in standard applications.
