Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386G-1-504 is determined by matching the following critical parameters:

• Resistance value: 500 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Square - 0.375" x 0.375" (9.53mm x 9.53mm)

The TT Electronics/BI 72PR500KLF meets all electrical and mechanical criteria for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386G-1-504 and 72PR500KLF are active products with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements:

The 72PR500KLF offers ROHS3 compliance and REACH unaffected status, making it suitable for applications subject to these regulatory frameworks. The 3386G-1-504 is RoHS non-compliant and REACH affected, requiring evaluation against specific application requirements and regional regulations.

Both parts share the same ECCN (EAR99) and HTSUS classification (8533.40.8050).

Frequently Asked Questions (FAQ)

Q: Can the 72PR500KLF directly replace the 3386G-1-504 in existing designs?

A: Yes. All electrical parameters (resistance, power rating, tolerance, temperature coefficient, number of turns) and mechanical specifications (mounting type, termination style, physical dimensions, adjustment type) are identical. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between these two parts?

A: The primary differences are packaging format (Tube vs. Bulk) and regulatory compliance status. The 72PR500KLF is ROHS3 compliant and REACH unaffected, while the 3386G-1-504 is RoHS non-compliant and REACH affected.

Q: Are there any performance differences between the Bourns and TT Electronics/BI versions?

A: No. Both parts share identical electrical performance specifications including resistance value, power rating, tolerance, and temperature coefficient.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements applicable to the end application. For applications requiring RoHS3 compliance or REACH compliance, the 72PR500KLF is the appropriate choice. Verify regulatory requirements before component selection.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tube or Bulk) does not affect electrical or mechanical performance. It relates only to order quantity and handling logistics.
