Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3262P-1-203LF 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 requirements for direct substitution. Both parts share identical resistance, power rating, tolerance, temperature coefficient, turn count, adjustment mechanism, resistive material composition, and termination configuration. Minor dimensional variation in the face width (0.185" versus 0.165") does not affect electrical performance or standard PCB layout compatibility for through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 3262P-1-203LF and 64XR20KLF are active production components with full regulatory compliance. The Bourns 3262P-1-203LF carries ROHS3 compliance and REACH Affected status. The TT Electronics/BI 64XR20KLF carries RoHS compliance with REACH Unaffected status and MSL rating of 1 (Unlimited), indicating superior moisture handling characteristics for storage and handling environments.

Selection between these parts should be based on supply chain availability, lead time requirements, and regulatory framework applicability. Both components satisfy identical electrical and mechanical requirements for 20 kOhms 0.25W trimmer potentiometer applications with side adjustment and PC pin termination.

Frequently Asked Questions (FAQ)

Q: Can the 64XR20KLF directly replace the 3262P-1-203LF in existing designs?

A: Yes. Both parts share identical electrical specifications (20 kOhms, 0.25W, ±10% tolerance, ±100ppm/°C temperature coefficient, 12-turn side adjustment, cermet resistive material, and PC pin termination). The minor face dimension difference (0.185" versus 0.165" width) does not affect through-hole PCB mounting or electrical performance.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant and carry the same ECCN (EAR99) and HTSUS classification. The 3262P-1-203LF is ROHS3 Compliant and REACH Affected. The 64XR20KLF is RoHS Compliant and REACH Unaffected with MSL 1 rating.

Q: What determines substitution eligibility for this trimmer potentiometer category?

A: Substitution requires matching resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, and termination style. All these parameters are identical between the 3262P-1-203LF and 64XR20KLF.

Q: Does the face dimension variation affect PCB layout?

A: No. The 0.020" width difference (0.250" x 0.185" versus 0.250" x 0.165") does not impact standard through-hole pad spacing or component placement for typical PCB designs.

Q: Which part should be selected for moisture-sensitive applications?

A: The 64XR20KLF carries MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage and handling, compared to the 3262P-1-203LF which lists MSL as Not Applicable.
