The remote is KDH281 with PCBA K03177 and program 1761. Its documented box is KDDYM002C with PCBA KD3143 and program 1760. Those program numbers belong to different components; they are not interchangeable revisions of one part.
Do not borrow a program from another manual
KDH281 also appears as a family reference around other reviewed Kaidi boxes. The dataset does not copy program 1761 onto those systems when their source fails to identify the handset configuration. KDDYM002D remains outside this specific pair.
How to use the qualified name
Record the product model, PCBA, and program separately, then compare all three with the table. If your label lacks a field, leave it missing and obtain supporting documentation. The slash-separated display below is a configuration label, not an invented manufacturer part number.

What we verified
Source-specific evidence
Read each row from original to target. A base application or box-to-remote pair is not a remote-to-remote replacement. Known constraints remain part of the decision.
Documented relationships; direction and exact scope matter
The manufacturer sample specification explicitly pairs these PCBA/program configurations. Confirm all identifiers; a generic family match does not satisfy this documented system scope.
