Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3386M-1-504 are qualified based on the following critical parameters:

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

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

Parameter Comparison

Engineering Selection Recommendations

Both the 3386M-1-504 and 72PR500KLF are active products with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

The 3386M-1-504 is RoHS non-compliant and REACH Affected. The 72PR500KLF is ROHS3 Compliant and REACH Unaffected, making it suitable for applications with regulatory compliance requirements.

Packaging differs between the two parts: the 3386M-1-504 is supplied in Tube packaging, while the 72PR500KLF is supplied in Bulk packaging. Procurement requirements and inventory management practices should guide packaging selection.

Both parts carry the same ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical electrical specifications (500 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, top adjustment, cermet material) and mechanical dimensions (0.375" x 0.375" square face). Both use PC pin termination for through-hole mounting. Direct substitution is electrically and mechanically compatible.

Q: What is the difference in RoHS compliance between these parts?

A: The 3386M-1-504 is RoHS non-compliant. The 72PR500KLF is ROHS3 Compliant. Applications subject to RoHS directives should use the 72PR500KLF.

Q: How do packaging options affect part selection?

A: The 3386M-1-504 is packaged in Tube format, while the 72PR500KLF is packaged in Bulk format. Tube packaging is suitable for smaller order quantities and manual handling. Bulk packaging is typically used for higher-volume automated assembly processes. Select based on production volume and assembly requirements.

Q: Are there differences in REACH compliance?

A: Yes. The 3386M-1-504 is REACH Affected, while the 72PR500KLF is REACH Unaffected. Applications requiring REACH compliance should use the 72PR500KLF.

Q: Do both parts have the same export classification?

A: Yes. Both parts are classified as EAR99 for export control purposes and share the same HTSUS code (8533.40.8050).
