Dynamo produced a much improved performance following a last-gasp defeat away to Romulus at the weekend.
But Long Eaton United's Tom Gamblen netted the winning spot-kick after a goalless 90 minutes.
United will face a home tie with Midland League Division One outfit NKF Burbage in the quarter-final.
The opening exchanges of the match were tepid. Neither side created much in the way of clear chances.
The first opportunity fell Long Eaton's way with 15 minutes played.
Charlie Scanlon sent a looping cross from the left into the penalty area. It found Reuben Wiggins-Thomas. He turned and fired a shot toward goal, but Brandon Ganley made a comfortable save.
Shepshed responded. Chris Acott delivered a cross into the box that found Liam Hurst at the far post. The midfielder sliced a shot wide.
The referee then ignored strident Dynamo cries for a penalty in the last notable action of an unremarkable half. A Long Eaton defender had appeared to have felled Sam Moore as the forward burst toward goal.
The quality of the match initially failed to improve after the break. Chances were still few. Two well-matched sides toiled to no avail.
It was not until the 66th minute that either team fashioned a clear opportunity to break the deadlock.
An excellent through ball released Celson Patrocinio on the right. He drove into a threatening position and pulled the ball back for Moore. The forward struck a tame shot into the grateful arms of away 'keeper Elliott Taylor.
Long Eaton then threatened on the counter attack. Gamblen found Wiggins-Thomas with a good through ball. The striker went for goal, but Jordan Wakeling made an important block.
In contrast to the bulk of its duration, the match ended in breathless fashion.
Dynamo forced a late corner. Hurst delivered the ball into the box. Chaos ensued. The hosts somehow failed to scramble in what would have been the winner.
Long Eaton cleared the danger and launched a swift counter. Wiggins-Thomas surged through on goal with only Ganley to beat. The Shepshed shot-stopper produced a brilliant save to push the ball away.
That was the final noteworthy action of the game. A penalty shoot-out followed.
Despite Sean Phillips, Karl Whymark and Matt Melbourne converting spot-kicks for Dynamo, Long Eaton emerged as the winners.
Taylor saved well from Hurst's penalty. Gamblen stepped up to fire home the winner shortly thereafter.
The defeat is Shepshed’s third in succession. Their play, perhaps, did not merit it. They manufactured a much better performance than in recent matches. Niall Prenderville produced a strong display in midfield as he so often has since joining the club three years ago. Joe Pheasant and Jake Betts also performed well in central defence.
But attentions must now turn to Saturday’s match at home to Sporting Khalsa. The Lions are directly above Dynamo in the table, occupying fourth place. Damion Beckford-Quailey’s men will hope to avenge their 2-0 defeat at the Aspray Arena last month.
