RSS-1524/H Equivalent & Substitute Parts

Part Overview

The RSS-1524/H is an isolated DC-DC converter manufactured by Recom Power. It features 1 output of 24V at 42mA, operates with a 13.5V to 16.5V input, delivers 1W output power, and offers a 3kV isolation voltage. The device is designed for ITE (Commercial) and Medical applications and operates in ambient temperatures from -40°C to 85°C. The RSS-1524/H supports surface-mount installation in an 8-SMD module, 5-lead package. It is RoHS3 compliant, REACH unaffected, and currently classified as Obsolete. Due to its product status, finding suitable alternative models is necessary to maintain system continuity.

Substitute Part Grouping Explanation

Substitution is determined strictly by comparing the following key parameters: input voltage range, output voltage and current, output power, isolation voltage, mounting type, package dimensions, operating temperature range, and environmental compliance (RoHS, REACH). Only parts that fully match these parameters can be considered direct substitutes in the isolated DC-DC converter category.

Engineering Selection Recommendations

The main part, RSS-1524/H, is Obsolete. The substitute part, R1S-1524/H, is Active and matches the electrical characteristics, environmental compliance (RoHS3, REACH), and mounting method. Product status and certifications are aligned with standard requirements for continuity and compliance.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for selecting a substitute for RSS-1524/H?
A1: Key parameters include input voltage range, output voltage and current, output power, isolation voltage, mounting type, package dimensions, operating temperature range, and compliance with RoHS and REACH.

Q2: Is R1S-1524/H fully compatible with RSS-1524/H in isolated DC-DC converter applications?
A2: R1S-1524/H matches all specified electrical, mechanical, and environmental parameters. Note minor differences in size/dimension should be considered for slot/footprint compatibility.

Q3: Are there differences in package or dimensions between the RSS-1524/H and R1S-1524/H?
A3: Both use the 8-SMD Module, 5 Leads package. The R1S-1524/H has a width of 10.7mm versus 8.2mm for RSS-1524/H and a height of 7.0mm versus 7.3mm.

Q4: Does RoHS3 and REACH compliance remain consistent between main and substitute parts?
A4: Both RSS-1524/H and R1S-1524/H are ROHS3 compliant and REACH unaffected.

Q5: Are there significant differences in temperature range or features?
A5: R1S-1524/H supports a wider temperature range (-40°C to 100°C) compared to RSS-1524/H (-40°C to 85°C). Other features remain consistent.
