Frequently Asked Questions
Is TQ-59 the same part as TQ59?
Yes. The can prints the number with a hyphen, and the same type number is also written TQ59. Both strings name the same part.
How do I orient it when swapping out an old TQ-59?
Note where the rim tab sits on the part coming out and set this one with its tab in the same position. The tab is the can's orientation reference.
Sprague printed its own house number on this can rather than a 2N registration, so the type line on its side carries the part's whole identity. Order by that line, hyphen or no hyphen.
