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 ASL193206BO attached. We reply within 48 hours.

How to read this table

Grade B:
Meets the electrical specification but is oversized on current or VA, or splits the primary differently (single 230 V against dual 115 V).

Every match here is electrical. Pin spacing and body size were not compared, so check the footprint against the datasheet above before you commit to a substitution. Send us the incumbent part number and we will confirm the mechanical fit with the quote.
