The documented KDH144 sample uses PCBA KD2096A and program 000907F. Its paired KDDYM002B box uses KD3152 and 001749. A separate KDH281 sample uses K03177 and 1761, with KDDYM002C / KD3143 / 1760.
These combinations are qualified configurations, not invented single part numbers. Leading zeroes and the final letter in 000907F are retained.
A familiar handset family is not enough
Other reviewed box records include KDDY109C(B) / KD3175 / 001751A and KDDYM002D / KD3232 / 001786. Their documents do not establish that the KDH281 program 1761 from another table belongs to them. They remain unpaired.
Ask for the missing configuration rather than guessing
If your label only says KDH281 or KDDYM002C, record the remaining label fields and compare them with the source table. The Finder will keep an unqualified family search Unknown. It will not reuse a known program just to produce a result.
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.
The manufacturer sample specification explicitly combines KDDYM002B (KD3152 / 001749) with KDH144 (KD2096A / 000907F). Other firmware or later KDH283C configurations are not included.
Use the model, PCBA number and program together. The display name combines separate source fields and is not a part number. Generic family identifiers cannot establish this sample configuration.
