SR10S1V8 Equivalent & Substitute Parts Reference

Part Overview

The SR10S1V8 (XP Power) is a DC DC converter designed as a linear regulator replacement with a single 1.8V output, supporting up to 1A and a wide input voltage (4.75V to 18V). The product status is listed as Obsolete. For continuing designs or maintenance, it is necessary to identify alternative models meeting the same electrical, thermal, mechanical, and regulatory requirements.

Q: Is package compatibility ensured?
A: Yes. Substitute TSR 1-2418 uses the same 3-SIP module package and identical dimensions.

Q: Are mounting and mechanical requirements matched?
A: Yes. Both parts use through-hole mounting and identical mechanical envelope.

Q: Are there differences in compliance or certifications?
A: Both SR10S1V8 and TSR 1-2418 are listed as ROHS3 compliant.

Q: Does TSR 1-2418 provide the same output capabilities as SR10S1V8?
A: Both provide 1.8V output at up to 1A, with efficiency listed at 82%.

Q: Are there differences in operating temperature?
A: TSR 1-2418 offers a wider operating temperature range (-40°C ~ 85°C with derating) compared to SR10S1V8 (-40°C ~ 60°C).

Q: Will the substitute part fit in the same PCB footprint?
A: Yes. Both use the same package and dimensions for direct replacement in compatible designs.

Q: Is commercial application support maintained?
A: Yes. Both are specified for ITE (Commercial) applications.
