Past Perfect is one of the English past tenses, used to indicate that one of 2 past actions took place before another, like in the sentence:

  • I had written my homework before I went for a walk.

Past Participle is one of the verb forms (usually the third form in a table of irregular verbs).

What's the difference?

    The past participle (written) is used in the formation of the past perfect tense (I had written). – Kate Bunting Sep 16 '21 at 13:43
  • Your title is about "past participles" but your question appears to be about "past perfect". Are you confusing the terms? If so, your question is a duplicate of this – gotube Sep 16 '21 at 16:39

Despite its name, the past participle is a non-finite verb form, which means that it has no tense. The past participle is used:

  • in forming the present perfect ("I have written")
  • in forming the past perfect ("I had written")
  • in forming the perfect infinitive ("(to) have written", as in "I must have written")
  • in forming passives ("it was written")
  • attributively as a descriptor ("a quickly written poem").

In many cases, the simple past is identical in form to the past participle ("I said", "I have said"). In other cases, they are different ("I did", "I have done").

Once you know what the past participle is, you can combine it with forms of "have" to form the present perfect and past perfect - hence there is no need for a table of irregular verb forms to include the past perfect: it just needs to include the past participle.
