Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6A504C01B00 is determined by strict alignment with the following electrical and mechanical parameters:

• Resistance value: 500 kOhms (exact match required)
• Power rating: 0.5W minimum
• Tolerance: ±10% or better
• Temperature coefficient: ±100ppm/°C or better
• Number of turns: 1 turn
• Adjustment type: Top adjustment
• Mounting: Through hole with PC pin termination
• RoHS3 compliance

Two substitute parts meet these criteria. The 3362P-1-504LF represents a direct manufacturer alternative from Bourns Inc. with active product status. The 72PR500KLF from TT Electronics/BI provides a similar functional alternative with active availability. Both parts maintain identical electrical specifications and mounting characteristics while differing in resistive material composition (cermet versus ceramic) and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The 3362P-1-504LF is the primary substitute option. It is manufactured by Bourns Inc., the original equipment manufacturer, maintains active product status with substantial inventory availability (65,600 pcs), and carries ROHS3 compliance certification. Physical dimensions are nearly identical to the original part (0.275" x 0.260" versus 0.272" x 0.272"), ensuring compatibility with existing PCB layouts and mechanical assemblies. The cermet resistive material provides equivalent electrical performance within the specified tolerance and temperature coefficient ranges.

The 72PR500KLF from TT Electronics/BI serves as a secondary alternative with active product status and ROHS3 compliance. This part maintains all required electrical specifications but features a larger physical footprint (0.375" x 0.375"), which may require PCB layout modification or mechanical clearance assessment before implementation.

Both substitutes are ROHS3 compliant and suitable for applications requiring environmental and regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can the 3362P-1-504LF directly replace the PVC6A504C01B00 without PCB modification?

A: The 3362P-1-504LF maintains PC pin termination and nearly identical face dimensions (0.275" x 0.260" versus 0.272" x 0.272"), making it suitable for direct PCB substitution in most applications. Minor dimensional variance is within typical PCB tolerance ranges for through-hole component placement.

Q: What is the difference between ceramic and cermet resistive materials in these trimmers?

A: Both ceramic and cermet materials meet the specified electrical parameters (500 kOhms, ±10% tolerance, ±100ppm/°C temperature coefficient) for this application. Cermet construction in the substitute parts provides equivalent functional performance within the defined operating range.

Q: Is the 72PR500KLF suitable for space-constrained applications?

A: The 72PR500KLF has a larger face dimension (0.375" x 0.375") compared to the original part (0.272" x 0.272"). Applications with limited PCB real estate should prioritize the 3362P-1-504LF, which maintains comparable dimensions to the obsolete part.

Q: Are all three parts RoHS3 compliant?

A: Yes. The PVC6A504C01B00, 3362P-1-504LF, and 72PR500KLF are all ROHS3 compliant, meeting environmental and regulatory requirements for restricted substance use.

Q: What inventory considerations apply to these substitutes?

A: The 3362P-1-504LF offers the highest inventory availability (65,600 pcs), followed by the 72PR500KLF (1,969 pcs). The original PVC6A504C01B00 has limited stock (697 pcs) and obsolete status, making substitution necessary for long-term supply continuity.
