Equivalent & Substitute Parts for DAS1004805
Part Overview
The DAS1004805 from Cosel USA, Inc. is an isolated PoE DC-DC converter delivering 5V at up to 20A with a maximum power rating of 100W. Its input voltage range is 88V to 370V, and it provides 500V isolation. The unit is designed for commercial ITE applications, offered in a through-hole 12-DIP module format with dimensions of 5.12" x 2.28" x 0.50". The DAS1004805 is currently classified as obsolete, making it essential to identify substitute or equivalent parts with matching or comparable electrical and mechanical specifications for continued product manufacturing and maintenance.

Engineering Selection Recommendations
When selecting substitutes for the DAS1004805, use only parts listed that offer RoHS-compliant status and meet application requirements for ITE (Commercial) use. The CBS1004805 and CHS1204805-B are both obsolete or active items from the same manufacturer, with RoHS3 compliance and through-hole mounting; both offer higher efficiency and wider operating temperature ranges, as specified. Regulatory classifications (ECCN/HTSUS) and moisture sensitivity level are matched for direct substitution purposes.
Frequently Asked Questions (FAQ)
Q1: What input voltage range differences exist between DAS1004805 and listed substitutes?
A1: DAS1004805 operates from 88V to 370V, while substitutes CBS1004805 and CHS1204805-B operate within 36V to 76V input range.
Q2: Are mounting types and package formats compatible?
A2: All parts use through-hole mounting. However, package/case formats differ: DAS1004805 uses 12-DIP, CBS1004805 uses 9-DIP, and CHS1204805-B uses 8-DIP modules. Mechanical compatibility must match the described dimensions and pin counts.
Q3: Do substitute parts meet RoHS requirements?
A3: Yes, all listed substitutes are RoHS or ROHS3 compliant.
Q4: Is the output voltage and current specification conserved among substitutes?
A4: All parts provide a 5V output. CBS1004805 matches the 20A rating; CHS1204805-B supports up to 24A.
Q5: Are substitute modules suitable for ITE (Commercial) applications?
A5: Yes, all listed modules are specified for ITE (Commercial) use.
