Compatible Replacement & Equivalent Models
When the LYA100A is discontinued, long lead-time, or out of budget, the following models may serve as functional equivalents. Always verify electrical ratings, pinout, and firmware compatibility before substitution.
| Model | Brand | Output Type | Points | Notes |
|---|---|---|---|---|
| LYA100A | Hitachi | Relay/Transistor | 16 | Original OEM part |
| LYA200A | Hitachi | Transistor | 32 | Expanded point count variant |
| LYA050A | Hitachi | Relay | 8 | Reduced point variant |
| QY10 | Mitsubishi | Relay | 16 | Cross-brand equivalent (verify bus compatibility) |
| CJ1W-OC211 | Omron | Relay | 16 | Cross-brand; requires adapter or rewiring |
Disclaimer: Cross-brand replacements require engineering validation. Konmask.com recommends using OEM parts wherever possible.

Consult your system’s hardware manual to confirm slot assignment and I/O mapping before installation.
Selection Guide
Use the following criteria to confirm the LYA100A is the right module for your application:
- Step 1 – Output Type: Confirm whether your load requires relay (AC/DC, higher current) or transistor (DC only, faster switching) output.
- Step 2 – Point Count: Verify 16 output points meets your I/O requirements; consider LYA050A (8pt) or LYA200A (32pt) if not.
- Step 3 – Load Voltage & Current: Match module ratings to your actuator/solenoid/relay coil specifications.
- Step 4 – Rack Slot: Confirm available slot in your H-series rack and total power consumption.
- Step 5 – Environment: Verify operating temperature, humidity, and vibration ratings match your installation site.

Replacement & Compatibility FAQ
Q: Can I use the LYA100A as a direct drop-in replacement for a failed module?
A: Yes, provided the replacement unit is the same part number and your rack firmware has not changed. Always power down the PLC before swapping modules.
Q: Is the LYA100A still in production?
A: Hitachi has transitioned some H-series products to end-of-life. Contact us to confirm current OEM availability or to discuss surplus stock options.
Q: Can I use a Mitsubishi QY10 instead of the LYA100A?
A: The QY10 has similar output specs but is not electrically or mechanically compatible with Hitachi H-series racks. Cross-brand substitution requires a custom interface or full panel redesign.
Q: Do you provide a warranty on the LYA100A?
A: New OEM units carry the manufacturer’s warranty. Refurbished units carry a 90-day Konmask.com functional warranty. Details available on request.
Q: What documentation can you provide for procurement?
A: We can provide commercial invoice, packing list, certificate of origin, and test reports upon request.
