Substitute Part Grouping Explanation

Substitution eligibility for the 3386H-1-101 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for direct substitution:

• Resistance value: 100 Ohms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Side 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)
• Series: Trimpot® 3386 - Sealed

The identified substitute part maintains complete electrical and mechanical compatibility while offering improved regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 3386H-1-101LF is a direct electrical and mechanical equivalent to the 3386H-1-101. Both parts are manufactured by Bourns Inc. within the Trimpot® 3386 sealed series and maintain identical performance specifications across all critical parameters.

The primary distinction between these parts is regulatory compliance status. The 3386H-1-101LF carries ROHS3 compliance certification and REACH unaffected status, whereas the 3386H-1-101 is RoHS non-compliant and REACH affected. For applications subject to RoHS3 or REACH regulatory requirements, the 3386H-1-101LF is the appropriate selection. Both parts share identical ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Component selection should be based on the regulatory requirements of the target application and market. Electrical performance and mechanical compatibility are equivalent between both options.

Frequently Asked Questions (FAQ)

Q: Can the 3386H-1-101LF be used as a direct replacement for the 3386H-1-101?

A: Yes. Both parts are electrically and mechanically identical. The 3386H-1-101LF differs only in regulatory compliance status, carrying ROHS3 certification and REACH unaffected designation. Direct substitution is valid from an engineering standpoint.

Q: What is the significance of the "LF" suffix in the 3386H-1-101LF part number?

A: The "LF" designation indicates lead-free construction, which aligns with ROHS3 compliance requirements. This affects the material composition of the termination and internal construction but does not alter electrical or mechanical performance specifications.

Q: Are there any performance differences between these two parts?

A: No. Both parts maintain identical resistance values, power ratings, tolerance, temperature coefficient, adjustment characteristics, and physical dimensions. Performance in circuit operation is equivalent.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements applicable to the end application. For designs subject to RoHS3 or REACH compliance mandates, the 3386H-1-101LF is the appropriate choice. Both parts are active in production and available in stock.

Q: Are the packaging and handling requirements the same?

A: Yes. Both parts are supplied in tube packaging and share identical moisture sensitivity level (not applicable) and handling requirements.
