Parameter Comparison

Engineering Selection Recommendations

Both the 3386F-1-500 and 3386F-1-500LF are functionally equivalent for applications requiring a 50 Ohm, 0.5W through-hole trimmer potentiometer with cermet material and top adjustment.

The primary distinction between these parts is compliance status. The 3386F-1-500LF carries ROHS3 compliance and REACH Unaffected status, making it suitable for applications subject to RoHS and REACH regulatory requirements. The 3386F-1-500 is RoHS non-compliant and REACH Affected, limiting its use in regulated markets.

For new designs or applications requiring compliance documentation, the 3386F-1-500LF is the appropriate selection. Both parts share identical electrical and mechanical specifications, ensuring direct functional interchangeability within compliant applications.

Frequently Asked Questions (FAQ)

Q: Can the 3386F-1-500LF replace the 3386F-1-500 in existing designs?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance, power rating, tolerance, temperature coefficient, adjustment type, and physical dimensions. The primary difference is compliance status.

Q: What is the significance of the "LF" suffix in the 3386F-1-500LF part number?

A: The "LF" designation indicates lead-free termination and RoHS3 compliance. This variant meets current environmental and regulatory standards for component manufacturing.
