Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3262P-1-203 is determined by strict equivalence across the following critical parameters:

• Resistance value: 20 kOhms
• Power rating: 0.25W (1/4W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 12
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins

The TT Electronics/BI 64XR20KLF meets all electrical and functional specifications. Minor dimensional variation in the face size (0.165" vs. 0.185") falls within acceptable mechanical tolerance for through-hole PCB mounting applications where the component footprint is not space-constrained to sub-millimeter precision.

Parameter Comparison

Engineering Selection Recommendations

The TT Electronics/BI 64XR20KLF is a direct functional equivalent to the Bourns 3262P-1-203 based on electrical specifications and mechanical compatibility. Selection between these parts should consider the following factors:

RoHS Compliance: The 64XR20KLF is RoHS Compliant, while the 3262P-1-203 is RoHS non-compliant. Applications subject to RoHS directives or customer requirements for lead-free components should specify the 64XR20KLF.

REACH Status: The 64XR20KLF is REACH Unaffected, whereas the 3262P-1-203 is REACH Affected. Procurement in regions with REACH regulatory requirements may favor the 64XR20KLF.

Moisture Sensitivity: The 64XR20KLF carries MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. The 3262P-1-203 lists MSL as Not Applicable.

Inventory Availability: The 64XR20KLF has significantly higher stock availability (11,252 units) compared to the 3262P-1-203 (979 units), supporting supply chain continuity for high-volume production.

Physical Dimensions: The 64XR20KLF has a slightly narrower face dimension (0.165" vs. 0.185"). Verify PCB layout and mechanical clearance requirements before substitution in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can the TT Electronics/BI 64XR20KLF replace the Bourns 3262P-1-203 in existing designs?

A: Yes, provided that PCB layout accommodates the minor face width difference (0.165" vs. 0.185"). All electrical parameters, resistance value, power rating, tolerance, temperature coefficient, and adjustment characteristics are equivalent. Verify mechanical clearance in your specific application.

Q: What is the significance of the RoHS compliance difference?

A: The 64XR20KLF is RoHS Compliant (lead-free), while the 3262P-1-203 is RoHS non-compliant. If your application or customer requirements mandate RoHS compliance, the 64XR20KLF is the appropriate selection.

Q: Are there any functional differences between the Trimpot® 3262 series and the 64 series?

A: Both series share identical electrical specifications for this 20 kOhms configuration. The primary differences are manufacturer (Bourns vs. TT Electronics/BI), series designation, and compliance certifications. Functional performance in the circuit is equivalent.

Q: How does the MSL rating affect component handling?

A: The 64XR20KLF carries MSL 1 (Unlimited), meaning it has no moisture sensitivity and requires no special storage or baking procedures. The 3262P-1-203 lists MSL as Not Applicable, indicating standard handling practices apply to both parts.

Q: Should I consider the inventory difference when selecting between these parts?

A: The 64XR20KLF has substantially higher stock availability (11,252 units vs. 979 units). For production schedules requiring large quantities or extended lead times, the 64XR20KLF provides better supply chain security.
