Mitsubishi Control Board KCZ-1342A YX304B113A-01

Mitsubishi Control Board KCZ-1342A YX304B113A-01 is used in Mitsubishi elevator control cabinet systems.

This PCB board is usually identified by the printed board code and part number on the original unit. In the elevator spare parts market, KCZ-1342A is commonly searched together with KCZ-1320A and YX304B113A-01, so customers often provide old board photos rather than only the elevator model when requesting this part.

For Mitsubishi elevator PCB replacement, the most important step is not only confirming the board name, but also checking the board version, connector position, cabinet wiring, and original control system configuration.

Related Board Numbers

This Mitsubishi control board may be searched under the following related references:

• KCZ-1342A
• KCZ-1320A
• YX304B113A-01
• KCZ-1320A KCZ-1342A
• Mitsubishi Elevator PCB Board KCZ-1342A
• Mitsubishi Elevator Control Board YX304B113A-01

KCZ series boards are used for different Mitsubishi elevator functions. For example, public listings show KCZ-1410A as a Mitsubishi light curtain power control board, while KCZ-910A / KCZ-910B and KCZ-1330B / KCZ-1331B are used in voice announcement board applications. This means a similar KCZ prefix does not mean the boards are interchangeable.

How Buyers Usually Confirm This Board

Most inquiries for KCZ-1342A come with a photo of the old PCB.

Before ordering, please confirm:

• KCZ-1342A marking on the board
• YX304B113A-01 part number
• whether KCZ-1320A is also printed or referenced
• connector quantity and position
• board size and mounting holes
• cabinet wiring condition
• front and back photos of the original PCB

For old Mitsubishi elevator systems, small differences in board version or connector layout may affect installation. If the old label is unclear, photos of the whole control cabinet and close-up PCB markings can help confirm the correct replacement.

Replacement Notes for Elevator Maintenance

Technicians usually check this type of control board when the elevator cabinet shows abnormal control response, communication issues, signal processing problems, or visible PCB damage.

However, a board fault should not be judged only by symptoms.

Before replacing KCZ-1342A YX304B113A-01, maintenance teams usually check:

• cabinet power supply condition
• wiring terminals
• fuse or protection circuit
• connector oxidation
• related signal boards
• original fault code or controller indication

In some cases, external wiring faults or unstable cabinet power may damage the replacement board if the root cause is not checked first.

Practical Reminder

Do not replace KCZ-1342A only by appearance.

KCZ series boards may look similar, but they can serve very different functions depending on the elevator system. The safest way to confirm this part is to match the exact PCB code, part number, connector structure, and original cabinet configuration.

If you are not sure whether your board is KCZ-1342A, KCZ-1320A, or another KCZ series PCB, please provide clear photos of the original board label and control cabinet.
