Key Parameters

Substitute Part Grouping Explanation

Substitution for the 3386P-1-205 is based on electrical and mechanical parameter equivalence within the Trimpot® 3386 sealed series. The substitute part must maintain identical specifications across all critical parameters: 2 MOhm resistance value, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, single-turn adjustment, top adjustment configuration, cermet resistive element, through-hole mounting, PC pin termination, and 0.375" x 0.375" square form factor.

The primary distinction between the main part and its substitute relates to RoHS compliance status and REACH classification, which do not affect electrical or mechanical performance but may be required for specific regulatory environments or procurement specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386P-1-205 and 3386P-1-205LF are functionally equivalent for circuit performance. Selection between these parts is determined by regulatory and compliance requirements rather than electrical characteristics.

The 3386P-1-205LF is the preferred selection for applications requiring RoHS3 compliance or REACH unaffected status. This variant is suitable for markets with strict environmental regulations and procurement policies mandating lead-free or restricted substance compliance.

The 3386P-1-205 remains suitable for applications where RoHS compliance is not a requirement and REACH affected status is acceptable. Both parts share identical electrical performance, mechanical dimensions, and operational characteristics.

Frequently Asked Questions (FAQ)

Q: Are the 3386P-1-205 and 3386P-1-205LF electrically interchangeable?

A: Yes. Both parts deliver identical electrical performance with 2 MOhm resistance, 0.5W power rating, ±10% tolerance, and ±100ppm/°C temperature coefficient. They are direct functional equivalents.

Q: What is the difference between these two part numbers?

A: The primary difference is compliance status. The 3386P-1-205LF is ROHS3 compliant and REACH unaffected, while the 3386P-1-205 is RoHS non-compliant and REACH affected. Electrical and mechanical specifications are identical.

Q: Can I use the 3386P-1-205LF as a direct replacement for the 3386P-1-205?

A: Yes. The 3386P-1-205LF is a direct substitute with identical form factor, pinout, and electrical characteristics. No circuit modifications are required.

Q: Which part should I specify for new designs?

A: Specify the 3386P-1-205LF for new designs unless legacy compliance requirements mandate the non-compliant variant. The LF version provides superior compliance coverage for current regulatory environments.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in tube packaging. Physical dimensions, mounting footprint, and PC pin configuration are identical.
