Substitute Part Grouping Explanation

Substitute parts for the 3262X-1-104LF are identified through strict parameter matching across electrical and mechanical specifications. The substitution criteria are:

• Resistance value: 100 kOhms (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 12 (exact match required)
• Adjustment type: Side Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)
• Face dimension: Rectangular format with compatible pitch and spacing

The TT Electronics/BI 64XR100KLF meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the Bourns 3262X-1-104LF and TT Electronics/BI 64XR100KLF are active products with full compliance certifications. The 3262X-1-104LF carries ROHS3 compliance and REACH Affected status. The 64XR100KLF carries RoHS compliance and REACH Unaffected status, which may be advantageous in applications subject to REACH regulatory requirements.

The face dimension variance (0.170" versus 0.165" height) is within typical PCB layout tolerances for through-hole components and does not affect electrical performance or functional compatibility. Both components share identical electrical specifications and mechanical mounting interfaces.

Selection between these parts should be based on supply chain availability, regulatory compliance requirements for the end application, and inventory status.

Frequently Asked Questions (FAQ)

Q: Can the 64XR100KLF directly replace the 3262X-1-104LF in existing designs?

A: Yes. Both components share identical electrical specifications (100 kOhms, 0.25W, ±10% tolerance, ±100ppm/°C temperature coefficient, 12-turn adjustment) and mechanical interfaces (through-hole PC pins, side adjustment). The minor face dimension difference (0.170" versus 0.165" height) does not affect PCB mounting or circuit performance.

Q: What is the significance of the REACH status difference?

A: The 3262X-1-104LF is REACH Affected, while the 64XR100KLF is REACH Unaffected. Applications subject to REACH compliance requirements may require the 64XR100KLF. Consult regulatory requirements for your specific application and end market.

Q: Are both parts available in the same packaging format?

A: Yes. Both the 3262X-1-104LF and 64XR100KLF are supplied in tube packaging, suitable for automated assembly and manual component handling.

Q: What determines substitution eligibility for this product category?

A: Substitution eligibility is determined by exact matching of resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, and termination style. Face dimension compatibility within standard PCB layout tolerances is also required.
