In United States v. DeMauro (D. N.H. Dkt. 17-cv-640-JL Order and Verdict After Bench Trial dtd. 8/28/20), CL here, the Court sustained the FBAR willful penalty but rejected the fraudulent failure to file penalty. In both cases, in broad strokes the conduct penalized is the same. If that statement is correct, the difference in outcome is based on the differing burdens of persuasion. The Government must prove application of the FBAR willful penalty by a preponderance of the evidence; the Government must application of the fraudulent failure to file penalty by clear and convincing evidence.
The willful FBAR penalty requires that the conduct penalized (failure to report) be willful. In the FBAR civil penalty context, the Courts have held willfulness is (i) specific knowing failure to file (more or less the Cheek standard) or (ii) willful blindness or reckless disregard of the obligation to report.
The fraudulent failure to file penalty, like the civil fraud penalty for filed returns companion in § 6663, requires fraud. The following is from my Federal Tax Procedure Book in discussing civil fraud under § 6663, but the same applies for the fraudulent failure to file:
The Code does not define fraud, but it may be viewed as the civil counterpart of criminal tax evasion in § 7201. n1 Examples of how courts have stated civil fraud under § 6663 are: (i) civil fraud requires “intentional commission of an act or acts for the specific purpose of evading tax believed to be due and owing”; n2 and (ii) civil fraud requires that “the taxpayer have intended to evade taxes known to be due and owing by conduct intended to conceal, mislead or otherwise prevent the collection of taxes and that is an underpayment.”n3 In making the determination, as with criminal cases, courts will often look to certain common patterns indicating fraud–referred to as badges of fraud, such as unreported income, failure to keep adequate books, dealing in cash, etc.n4 The key differences between the two is that § 6663 is a civil penalty and has a lower burden of proof (clear and convincing rather than beyond a reasonable doubt) as I note later.

Commissioner, 763 F. 2d 1139, 1142-1143 (3rd Cir. 1985) (“Fraud means "actual, intentional wrongdoing, and the intent required is the specific purpose to evade a tax believed to be owing.”); and Fiore v. Commissioner, T.C. Memo. 2013-21 (“Fraud is the ‘willful attempt to evade tax’” and using the criminal law concept of willful blindness to find the presence of civil fraud; note that, in the criminal law, the concept of willful blindness goes by several names.)

Commissioner, T.C. Memo. 2012-214.
