Stick with the old ignition module, regardless of how nasty it looks ... but keep a replacement handy in case it finally fails.
Personal impression: The electronics manufacturing industry has declined notably over the decades, mostly due to cost-cutting and increasingly lax quality control. So, if something fail sooner than I'd reasonably expect, I try to determine who manufactured it and where it was manufactured so I can avoid their products henceforth.
Case in point: Over a decade ago, GM quietly decided seat warmers didn't need to work below -20 degrees F. (Yes, a truly remarkable lack of logic and understanding of reality.) You should have heard the CarQuest assistant manager when he found out that was why the seat warmers in his relatively new 2005 Silverado HD quit working. Multiple electronic control modules went into permanent fault mode when he turned them on at the seriously subzero (-30 to -40 degrees F) temperatures in interior Alaska.
Have you tried a genuine OEM Dodge ignition module? It may be a bit more expensive but I'd trust it more ... they have more at stake in terms of reputation than after-market manufacturers.
Note: OEM parts and dealer parts counters have long suffered a reputation for overly expensive parts. This is no longer a reality. Several decades ago, the Big Three realized they were losing out on a very large potential market, due to 'inflated' prices. So, they began to make efforts to make their parts and dealerships more competitive with independent and chain parts stores.
Their prices still tend to be a bit higher but it's now mostly due to better quality products. In some cases I've encountered personally, the dealership prices have actually been less than other sources, with better quality.
So, I prefer to stick with original electronic components until they fail. (Especially in terms of older Dodge ignition components.) When they fail, I try very hard to get original OEM parts, not OEM-equivalent parts.
I've run into the same issue with computer components ... it was/is an ongoing and tediously long-standing problem in the Air Force. Planes falling out of the sky due to faulty/substandard electronics is "embarrassing." (It not hard to find reports identifying substandard components as the cause of major malfunctions.)
