ASL152124

3 VA · EI42 · 230 V primary · 24 V secondary at 125 mA

ASL152124 is discontinued and cannot be ordered

The 3VA-EI42-8.5 series has been withdrawn from Aslan Elektronik's current catalog. This page and its datasheet stay published for anyone maintaining a design that already uses this part.

These active parts carry the same 24 V secondary at or above 3 VA. They are a different core, so confirm the footprint against the datasheet before you substitute.

How this part is supplied

Aslan Elektronik builds to order and ships direct from the factory. S&B Tech is its exclusive North American representative, not a stocking distributor, so pricing comes back with the quote at your volume. Lead time is two weeks.

A secondary voltage, cover style, or footprint outside this table is a custom wind, which is normal business here rather than an exception.

Both arrive with ASL152124 attached. We reply within 48 hours.
