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

Part Overview

The Bourns 3262P-1-202 is a 2 kOhm, 0.25W through-hole trimmer potentiometer with PC pin termination and side adjustment. This sealed Trimpot® 3262 series component is designed for precision resistance adjustment in electronic circuits requiring reliable, long-term stability. The part is currently active in production with 1075 units in stock. Substitute parts may be required due to supply constraints, end-of-life considerations, or specific compliance requirements for target applications.

Key Parameters

Substitute Part Grouping Explanation

The TT Electronics/BI 64XR2KLF qualifies as a direct substitute for the Bourns 3262P-1-202 based on the following critical parameters:

• Resistance Value: Both parts are 2 kOhms
• Power Rating: Both rated at 0.25W (1/4W)
• Tolerance: Both maintain ±10% tolerance
• Temperature Coefficient: Both specify ±100ppm/°C
• Number of Turns: Both feature 12-turn adjustment
• Adjustment Type: Both use side adjustment
• Resistive Material: Both employ Cermet technology
• Mounting Type: Both are through-hole mounted
• Termination Style: Both use PC pins
• HTSUS Classification: Both classified under 8533.40.8050

The 64XR2KLF maintains functional and electrical equivalence across all specified parameters. Physical dimensions differ slightly (0.165" vs 0.185" face height), but this represents a minor variation within standard PCB layout tolerances for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both the Bourns 3262P-1-202 and TT Electronics/BI 64XR2KLF are active production components with identical electrical specifications and functional performance. Selection between these parts should be based on the following factors:

Compliance Requirements: The 64XR2KLF is RoHS Compliant and REACH Unaffected, making it the preferred choice for applications subject to EU environmental regulations. The 3262P-1-202 is RoHS non-compliant and REACH Affected, which may restrict its use in regulated markets.

Moisture Sensitivity: The 64XR2KLF carries an MSL rating of 1 (Unlimited), indicating superior moisture resistance and broader storage/handling flexibility. The 3262P-1-202 has no MSL rating specified.

Inventory Availability: The 64XR2KLF offers significantly higher stock availability (9655 units) compared to the 3262P-1-202 (1075 units), providing supply chain advantages for high-volume production.

Physical Footprint: The 64XR2KLF has a slightly reduced face height (0.165" vs 0.185"), which may provide marginal PCB layout benefits in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Are the Bourns 3262P-1-202 and TT Electronics/BI 64XR2KLF electrically identical?

A: Yes. Both parts share identical resistance (2 kOhms), power rating (0.25W), tolerance (±10%), temperature coefficient (±100ppm/°C), and turn count (12). They are functionally equivalent for circuit operation.

Q: Will the 64XR2KLF fit in a PCB layout designed for the 3262P-1-202?

A: Yes. Both parts use identical mounting type (through-hole), termination style (PC pins), and primary face dimension (0.250" width). The face height difference (0.185" vs 0.165") is minor and does not affect standard PCB mounting compatibility.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS or REACH compliance requirements, the 64XR2KLF is the appropriate choice. For applications without regulatory constraints, either part is functionally suitable; however, the 64XR2KLF offers superior compliance status and higher inventory availability.

Q: Are there any performance differences between these parts?

A: No. Both parts specify identical electrical performance parameters: tolerance, temperature coefficient, and resistive material (Cermet). Performance in circuit operation is equivalent.

Q: What is the significance of the MSL rating difference?

A: The 64XR2KLF's MSL 1 rating indicates unlimited shelf life and moisture exposure tolerance, providing greater flexibility in storage and handling. The 3262P-1-202 has no MSL specification, which may impose restrictions on storage conditions in moisture-sensitive environments.
