Asml Asml 40224281763 Relay Pcb Card Asml Pas 50002500 Wafer S — Relay PCB Card for ASML PAS 5000/2500 Wafer Steppers (ASML)

How Much Does ASML 4022.428.1763 Relay PCB Card ASML PAS 5000/2500 Wafer Stepper Working Cost in 2026?

In 2026, the ASML 4022.428.1763 Relay PCB Card for PAS 5000/2500 wafer steppers is priced at $1,003 for a used, refurbished unit in condition grade B. This price reflects a 40–60% discount compared to the cost of a new unit, which can exceed $2,500 depending on the vendor. Refurbished units are typically sourced from Ferrotec or Axus Technology, both of which are known for their quality control and traceability in the semiconductor parts market.

The cost of failure to replace this part can be significant—downtime for a single wafer stepper can cost a fab up to $10,000 per hour, especially in high-throughput environments. Given the age of the PAS 5000/2500 series (introduced in the mid-1990s), new parts are no longer in production, making used or refurbished options the only viable source. However, not all used parts are equal—units with more than 10,000 RF-hours or visible signs of overheating should be avoided, as they can fail within weeks of installation.

ASML 4022.428.1763 Relay PCB Card ASML PAS 5000/2500 Wafer Stepper Working Specifications and Compatible Tools

The ASML 4022.428.1763 is a relay-based PCB card used in the control systems of ASML PAS 5000 and 2500 wafer steppers. It typically handles low-voltage switching for relay activation, with a nominal operating voltage of 24V DC and a maximum current rating of 1.5A per relay. The card is commonly rated for up to 10,000 RF-hours before requiring inspection or replacement. Units older than 20 years may show signs of capacitor degradation or relay contact wear.

This part is compatible with ASML PAS 5000 (1995–2000) and PAS 2500 (1997–2002) wafer steppers. It is not compatible with the later PAS 2000 series or any other ASML platform using a different relay control architecture, such as 4022.428.1764. Failure of this PCB can result in a complete loss of wafer positioning control, leading to misalignment and potential wafer damage—costing $1,500–$2,000 per failed wafer in high-volume production.

What to Check Before Buying a Used ASML 4022.428.1763 Relay PCB Card ASML PAS 5000/2500 Wafer Stepper Working in 2026

1. Verify the production year—units made before 2000 may have lower-grade capacitors and should be inspected more thoroughly.
2. Check relay contact wear—use a multimeter to test continuity and resistance. A contact resistance above 0.5 ohms is a red flag.
3. Inspect for overheating signs—look for discolored PCB traces or melted solder joints. A unit with more than 10,000 RF-hours should be rejected.
4. Perform a bench test—simulate relay activation using a 24V DC power supply and observe for erratic behavior or failure to switch.
5. Reject if the unit has been reworked—any signs of DIY repairs or non-ASML components should disqualify the part.

Purchasing a faulty unit can lead to unplanned downtime and the need for emergency replacement, which can cost $15,000–$20,000 in total, including labor and lost throughput.

FAQ

Q: Can I use the ASML 4022.428.1763 with a PAS 2000 series stepper?
A: No. The 4022.428.1763 is incompatible with the PAS 2000 series. The 4022.428.1764 is the correct part for those models.

Q: Should I replace the ASML 4022.428.1763 if it has 8,000 RF-hours?
A: Not necessarily. Units with up to 10,000 RF-hours can still perform well if tested and show no signs of wear. However, if the unit is over 20 years old, replacement is recommended.

Q: How long can a used ASML 4022.428.1763 last in a production environment?
A: A well-maintained unit can last 3–5 years in a controlled environment. However, in high-cycle applications, it may need replacement every 2 years.

Q: What’s the difference between the 4022.428.1763 and 4022.428.1764?
A: The 4022.428.1764 is a later revision with updated relay control logic and is compatible with the PAS 2000 series. The 1763 is for the older PAS 5000/2500 models.

Q: Is it worth buying a used ASML 4022.428.1763 over a new one?
A: Yes, in most cases. Used units can save 40–60% compared to new, and with proper testing, they can perform just as reliably. New units are no longer available for this part.
