The sample specification distinguishes PCBA K03177 and program 1761. The generic family name is insufficient to confirm this exact configuration.
Replacement fit is not confirmed by the family name. Copy the full part number and revision from the remote back, battery compartment or accessible control-box label. If it is unsafe to reach a label, ask for help.
For support, record the complete remote and control-box labels, base model, revision and observed symptom. Ask the manufacturer to confirm a directed replacement and any pairing or feature limitations in writing.
The documented configuration
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 check all three fields
Copy the model, PCBA, and program onto separate lines and compare them with the table. If a field is missing, leave it unknown and look for documentation for your part. The slash-separated name below combines those fields for display; it isn’t a manufacturer part number.

Detailed relationship records and source claims
What the sources confirm
Source-specific evidence
Read each match in the direction shown and check its conditions. A listed base or control-box match tells you which remote it uses; it doesn’t name a replacement for another remote.
Documented matches: check the direction and conditions
The manufacturer sample specification explicitly pairs these PCBA/program configurations. Confirm all identifiers; a generic family match does not satisfy this documented system scope.
No. It is the PCBA identifier within the reviewed KDH281 configuration.
Will KDH281 alone return a verified match?
No. The exact configuration and documented system scope are required.
