N4 · Using the te-form
ないで and なくて: without doing, and because not
the two negative te-forms
ないで says how something is done or what is done instead; なくて gives a reason.
The plain negative in ない has two te-forms, and they do different jobs. ないで describes the circumstances of the next action — "without doing": 朝ご飯を食べないで学校に行きました, "I went to school without having breakfast". It can also mean "instead of": バスに乗らないで、歩いて帰りました, "instead of taking the bus, I walked home".
なくて gives a reason: something did not happen, and that led to what follows. 日本語が分からなくて、困りました, "I didn't understand Japanese, and I was stuck". What follows is usually a feeling or a state the speaker did not choose.
Adjectives and nouns have only なくて: 高くなくて, 静かじゃなくて, 学生じゃなくて. ないで exists only for verbs. The forms なくてもいい and なくてはいけない are also built on なくて, never on ないで.
English speakers have a quick test available. If the English sentence can take "without", the Japanese takes ないで; if it says "because … not" or "… didn't, so", it takes なくて. In writing, ないで is often replaced by ずに: 何も言わずに, "without saying anything".

The rules one by one
ないで says that an action happens without another one.
傘を持たないで出かけました。I went out without an umbrella.
ないで also says what was done instead of something else.
タクシーに乗らないで、歩いて帰りました。Instead of taking a taxi, I walked home.
なくて gives a reason, and what follows is a feeling or a state.
試験に合格できなくて、残念でした。I was disappointed not to pass the exam.
Adjectives and nouns have only なくて; ないで is for verbs.
この部屋は広くなくて、少し不便です。This room isn't very big, which is a little inconvenient.
A closer look
Why the second half decides
After なくて, the second half states a consequence the speaker did not choose: a feeling (困った, 残念だ, 心配だ), a difficulty, a result. A decision, a request or a suggestion cannot follow it. "We have no time, so let's take a taxi" needs から or ので: 時間がないから、タクシーで行きましょう.
After ないで, the second half is the main action, and the first describes the way it was done or what was done instead. That is why ないで can stand before a request — 辞書を使わないで書いてください — while なくて cannot.
Exceptions and special cases (1)
-
a reason is followed by a request, a suggestion or a decision
なくて cannot be used; switch to ないから or ないので.
時間がないから、タクシーで行きましょう。We haven't got much time, so let's take a taxi.
なくて links a cause to a result nobody chose. A request is a choice, so the link has to be an explicit "because".

Worth knowing (1)
-
じゃなくて: not this but that
After a noun, じゃなくて — in writing ではなく — corrects one thing with another. It is one of the commonest uses of the negative te-form in conversation, and it has nothing to do with reasons.
会議は三時じゃなくて、四時からです。The meeting starts at four, not three.
The trap English speakers fall into
Watch out
"Without sugar" describes how the coffee is drunk, so the form is ないで. なくて would make it a reason — "because I don't put sugar in, I drink coffee" — which is not what anyone means.
If English says "without", use ないで; if it says "because not", use なくて.
