How to define a specific electrical impedance symbol in Circuitikz: a rectangle filled with diagonal red lines at equal intervals?

Question

How to define a specific electrical impedance symbol in Circuitikz: a rectangle filled with diagonal red lines at equal intervals? See the desired output below.

My Desired Output:

My Current Output:

My Current Code:

\documentclass{article}

\usepackage{circuitikz}

\begin{document}

        \begin{circuitikz}[european]

            \draw (0,0) to[R=$R$](0,5);

        \end{circuitikz}

\end{document}

Answer 1

I'm assuming the lines should rotate with the shape which is why I'm not using a pattern here (which could also be rotated but then we would have to smuggle the orientation into the shape's definition or use a shape and another drawing which I don't know how to approach in Circuitikz).

Here, is a definition that draws the lines manually

The angle as well as the color can be set via keys, the distance between the lines is fixes.

Code

\documentclass[varwidth]{standalone}
\usepackage{circuitikz}
\makeatletter
\ctikzset{
  bipoles/sssgeneric/angle/.initial=60,
  bipoles/sssgeneric/color/.initial=red,
}

      \pgfpathrectanglecorners{\pgfpoint{\pgf@circ@res@left}{\pgf@circ@res@up}}
                              {\pgfpoint{\pgf@circ@res@right}{\pgf@circ@res@down}}
      \pgfusepathqclip

      \pgfmathsetlengthmacro\@@ctikz@x{%

You can copy from pgfcircbipoles.tex the component (in this case, it is generic, which is used for the European-style resistor), and add a pattern.

\documentclass{article}
\usepackage{circuitikz}
\usetikzlibrary{patterns.meta, patterns}
\makeatletter
\pgfcircdeclarebipolescaled{resistors}
{}
{\ctikzvalof{bipoles/generic/height}}
{stripedgeneric}
{\ctikzvalof{bipoles/generic/height}}
{\ctikzvalof{bipoles/generic/width}}
{
    % \pgf@circ@debug@colors
    \pgfsetfillpattern{north east lines}{red}
    \pgfpathrectanglecorners{\pgfpoint{\pgf@circ@res@left}{\pgf@circ@res@up}}{\pgfpoint{\pgf@circ@res@right}{\pgf@circ@res@down}}
    \pgf@circ@setlinewidth{bipoles}{\pgfstartlinewidth}
    \pgfusepath{draw, fill}
}
\pgfcirc@activate@bipole@simple{l}{stripedgeneric}
\makeatother

\begin{document}

\begin{circuitikz}[european]
    \draw (0,0) to[stripedgeneric=$R$] (0,5);
\end{circuitikz}

\end{document}
