The part is likely a Chinese OEM relay or terminal block with a UL94 V-0 plastic case. To get the real datasheet, search manufacturer KLS Electronic (Kunlian) or replace the part based on electrical specs. For the 94V-0 material standard, refer to UL 94 standard document (free summary from UL.com) .

What is this specific board installed inside?
: Often identified as a 20x4 character LCD or a graphical module depending on the specific equipment it services. kl sn102 94v 0 datasheet pdf 18 exclusive
: Frequently powered by industry-standard legacy controllers such as the Hitachi HD44780 or compatible graphic dot-matrix controllers.
: Contact KLS Electronic Co., Ltd. directly (or the distributor from which you saw “KL SN102”) and ask for their “SN102-18” variant datasheet – the “18” may be their internal code for an 18-pin or 18A contact version.
The KL SN102 is a small-signal semiconductor device (assumed to be a transistor, diode, or regulator family member — exact function varies by manufacturer). It meets UL 94V-0 flammability standard for printed circuit board materials or component housings, indicating self-extinguishing behavior and minimal dripping when exposed to flame. The part is likely a Chinese OEM relay
: This is the most ambiguous part and likely refers to the internal model number for the assembled LCD module , which includes the glass display, the attached PCB (Printed Circuit Board), and its controller logic. Alternatively, in some contexts, it might be a marking for the bare PCB itself. As one forum user aptly notes, "KL SN102 might be just some other markings on the PCB". This ambiguity is common with legacy or non-branded modules, where the manufacturer's internal codes are not widely published or standardized.
