PWDI13159 is a choke for the Collins 30S-1, listed as an exact replacement for L-202. It is part of Hammond's PWDAHL Series, the transformers and chokes catalogued directly from the Peter W. Dahl files of magnetics for amateur radio products, and it is aimed at 30S-1 owners and restoration technicians.

The choke is rated 8.0 HY @ 0.5A DC with 10 KVDC insulation, suitable for matching the original L-202 position.

PWDI13159 is wound on an EI-175 x 3 core and listed as Style 5 on the series style sheet. The ordering table gives an approximate weight of 19 lbs, while the part page lists a shipping weight of 6.44 lbs (2.92 kg); confirm the figure with Hammond when planning freight. The part is REACH compliant and RoHS compliant.

Hammond notes that PWDAHL units are usually built to order one at a time and recommends confirming availability by phone or e-mail. For records, the part carries UPC 623980436036 and UNSPSC 39121301. The 30S-1 T-102 ALC transformer is also available in this series as PWDA13244.

The 10 KVDC insulation rating and the 0.5A DC current rating are the key values to confirm against the original L-202 when servicing the 30S-1.
