When you work on controls, the replacement part you need is either a full circuit board or a single relay. In the relays, contactors, and industrial switches category, these two spares take different approaches: one is a complete PCB, the other is a standalone relay. Choosing the wrong one means another shutdown while you wait for the right component, so it pays to map the part to the repair.
Quick verdict
If your system calls for the exact AMS 4419 Rev G board, the $79.00 AMS 4419 Rev G Industrial Control Relay PCB CN8-A 82350 V1.06 is the one to match. If you only need a basic relay for a 250V 6A circuit, the $15.00 INDUSTRIAL SPARE AC250V6A RELAY NSNP makes more sense. Let the failed component's part number decide, not the price alone.
Price and condition at a glance
| Product | Listed Price | Condition | Price Bar |
|---|---|---|---|
| AMS 4419 Rev G Industrial Control Relay PCB CN8-A 82350 V1.06 | USD 79.00 | For parts or not working | |
| INDUSTRIAL SPARE AC250V6A RELAY NSNP | USD 15.00 | New - Open box |
Where each product wins
The AMS 4419 Rev G wins when the repair depends on that specific control PCB. It is the only full circuit board in this head-to-head, and the CN8-A 82350 V1.06 marking gives you a concrete reference to compare against your existing board.
The INDUSTRIAL SPARE AC250V6A wins when you need a straightforward relay. The AC250V6A rating is stated right in the title, so you know it is intended for 250V circuits running up to 6A.
Product notes
AMS 4419 Rev G Industrial Control Relay PCB CN8-A 82350 V1.06
This board sits at the high end of the pair's $15-$79 range, but it is the only module here that gives you a full PCB rather than just a relay. The AMS 4419 Rev G designation and the CN8-A 82350 V1.06 marking are concrete identifiers for matching a failed board. The catch is condition: this board has not been powered on or functionally tested, and it may carry dust, scratches, labels, or wiring from previous use. It is sold as-is for parts or repair, which means you should plan to inspect it yourself before relying on it. Choose it when the part number match matters more than plug-and-play certainty.
INDUSTRIAL SPARE AC250V6A RELAY NSNP
This relay sits at the low end of the pair's price spread, and its new, open-box condition sets it apart from the untested PCB. The AC250V6A rating tells you it handles 250V circuits up to 6A, while the NSNP suffix gives you a specific reference for ordering. A 30-day return window is included, which adds peace of mind for such a low-cost spare. The limitation is scope: this is a relay, not a control board, so it cannot replace a full PCB like the AMS 4419 Rev G. If your repair only needs a relay swap, this is the simpler, lower-priced option.
Final choice by use case
Pick the AMS 4419 Rev G board when you already know your system needs that exact PCB. The higher price buys a specific board identity, and you accept the condition it is sold in.
Pick the INDUSTRIAL SPARE AC250V6A relay when you want a lower-priced relay for a 250V 6A circuit. Its price makes it the easy spare to keep around.
If you cannot tell whether the relay or the control board is at fault, start by reading the part number on the failed component. The AMS board is for exact board replacement; the AC250V6A relay is for simple relay replacement.
