Substitute Part Grouping Explanation

Substitution eligibility for the 3386X-1-501 is determined by strict equivalence across the following critical parameters:

• Resistance value: 500 Ohms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1 Turn
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical size: Square - 0.375" x 0.375" (9.53mm x 9.53mm)
• Series: Trimpot® 3386 - Sealed

The 3386X-1-501LF variant meets all electrical and mechanical requirements for direct substitution. The primary distinction between these parts relates to RoHS compliance status and REACH regulatory classification, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386X-1-501 and 3386X-1-501LF are functionally equivalent trimmer potentiometers with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements:

The 3386X-1-501LF is the appropriate choice for applications subject to RoHS3 compliance mandates or REACH-restricted substance regulations. This variant eliminates lead and other restricted substances while maintaining full electrical and mechanical compatibility.

The 3386X-1-501 remains suitable for applications without RoHS3 or REACH compliance requirements, or where legacy component specifications are mandated by design documentation.

Both parts share the same ECCN classification (EAR99) and HTSUS code (8533.40.8050), indicating equivalent export control and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 3386X-1-501LF be used as a direct replacement for the 3386X-1-501?

A: Yes. Both parts are electrically and mechanically identical. The 3386X-1-501LF differs only in RoHS and REACH compliance status. Substitution is valid for all applications where the compliance profile of the 3386X-1-501LF meets design and regulatory requirements.

Q: What is the difference between RoHS non-compliant and ROHS3 Compliant status?

A: The 3386X-1-501 is manufactured without RoHS3 restrictions, while the 3386X-1-501LF is manufactured to comply with RoHS3 directives, which restrict hazardous substances including lead, cadmium, and mercury. Selection depends on end-product regulatory requirements.

Q: Are there differences in performance or reliability between these parts?

A: No. Both parts deliver identical performance across all electrical parameters: 500 Ohm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, and 1-turn side adjustment. Reliability and performance characteristics are equivalent.

Q: What does REACH Affected versus REACH Unaffected mean?

A: REACH Affected indicates the part may contain substances of concern under REACH regulations. REACH Unaffected indicates the part is manufactured to avoid such substances. Selection depends on supply chain and end-market regulatory requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts are square format, 0.375" x 0.375" (9.53mm x 9.53mm) with identical through-hole PC pin termination and side adjustment configuration.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Identical footprint, mounting type, and termination style ensure direct PCB compatibility. No design modifications are required when substituting between these parts.
