Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3262P-1-501LF are qualified based on the following critical parameters:

• Resistance value: 500 Ohms (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)

The TT Electronics/BI 64XR500LF meets all critical electrical and mechanical parameters, qualifying it as a direct functional substitute. Minor variations in face dimension (0.165" vs 0.185" height) remain within acceptable tolerance for standard PCB layout applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Bourns 3262P-1-501LF and TT Electronics/BI 64XR500LF are active products with current manufacturing status. The 3262P-1-501LF carries ROHS3 compliance certification, while the 64XR500LF maintains RoHS compliance. Both components are classified under ECCN EAR99 and share identical HTSUS commodity codes, confirming regulatory alignment for industrial applications.

Selection between these parts should be based on supply chain availability, lead time requirements, and inventory status. The Bourns component currently maintains 927 units in stock, while the TT Electronics/BI alternative has 1,424 units available. Both parts satisfy identical electrical performance requirements and mechanical interface specifications for direct substitution in through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the TT Electronics/BI 64XR500LF directly replace the Bourns 3262P-1-501LF?

A: Yes. Both components share identical electrical specifications (500 Ohms, 0.25W, ±10% tolerance, ±100ppm/°C temperature coefficient, 12-turn side adjustment) and mechanical interfaces (through-hole mounting, PC pin termination). The minor face dimension difference (0.185" vs 0.165" height) does not affect PCB layout compatibility for standard applications.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant and classified as EAR99 for export control purposes. The Bourns part carries ROHS3 certification, while the TT Electronics/BI part carries standard RoHS certification. Both meet regulatory requirements for industrial electronics applications.

Q: What is the significance of the 12-turn specification?

A: The 12-turn specification indicates the potentiometer requires 12 complete rotations of the adjustment screw to traverse the full resistance range. This parameter must match exactly for functional equivalence, as it determines adjustment resolution and mechanical interface compatibility.

Q: Does the resistive material (Cermet) affect substitution eligibility?

A: Yes. Cermet (ceramic-metal composite) is a critical specification that determines temperature stability, noise characteristics, and long-term reliability. Both qualified substitutes use identical Cermet material, ensuring equivalent performance across operating temperature ranges.

Q: What packaging format is used for these components?

A: Both the Bourns 3262P-1-501LF and TT Electronics/BI 64XR500LF are supplied in tube packaging, suitable for automated assembly processes and manual component handling.
