Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3386R-1-504 are identified based on strict equivalence across the following critical parameters: resistance value (500 kOhms), power rating (0.5W), 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), and physical dimensions (0.375" x 0.375" square face). Parts meeting all these specifications are electrically and mechanically interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386R-1-504 and 72PR500KLF are active production parts with identical electrical and mechanical specifications. The primary differentiation lies in regulatory compliance status. The 3386R-1-504 is RoHS non-compliant and REACH affected. The 72PR500KLF is ROHS3 compliant and REACH unaffected. Selection between these parts should be based on the regulatory requirements of the end application and target market. Both parts carry the same ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Frequently Asked Questions (FAQ)

Q: Are the 3386R-1-504 and 72PR500KLF electrically identical? A: Yes. Both parts share identical resistance (500 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), and all other electrical specifications.

Q: Can these parts be used interchangeably on the same PCB? A: Yes. Both parts have identical physical dimensions (0.375" x 0.375" square face), through-hole mounting type, and PC pin termination, making them mechanically compatible for direct substitution.

Q: What is the difference between these two parts? A: The primary differences are packaging format (3386R-1-504 supplied in tube; 72PR500KLF supplied in bulk) and regulatory compliance status (3386R-1-504 is RoHS non-compliant; 72PR500KLF is ROHS3 compliant).

Q: Which part should I select for new designs? A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, use 72PR500KLF. For applications without RoHS requirements, either part is suitable based on availability and packaging preference.

Q: Are there inventory differences between these parts? A: Yes. The 3386R-1-504 has 1051 pcs in stock, while 72PR500KLF has 1969 pcs in stock. Availability should be confirmed at time of procurement.
