Equivalent & Substitute Parts Reference: RZ-2412S/P

Part Overview

RZ-2412S/P is an isolated DC-DC converter module manufactured by Recom Power. It provides a single 12V output at up to 42mA from an input voltage range of 21.6V to 26.4V, with 500mW output power. The module features 1kV isolation, surface mount packaging, SCP (short-circuit protection), and supports operating temperatures from -40°C to 70°C. The product is classified as obsolete. Sourcing alternative models is necessary to maintain continued design support and inventory availability.

Engineering Selection Recommendations

RZ-2412S/P is obsolete. R0.5Z-2412/P is active and meets RoHS3 and REACH compliance, and matches all environmental and regulatory certifications specified. Moisture Sensitivity Level for both parts is 1 (unlimited), suitable for direct replacement in surface mount applications. The substitute part supports the same compliance requirements as the main part number.

Frequently Asked Questions (FAQ)

Q: What are the required matching parameters for substitution in DC-DC converter modules?
A: Input voltage range, output voltage, output current, isolation voltage, mounting type, package/case, power rating, and compliance certifications are required for substitution.

Q: Are RZ-2412S/P and R0.5Z-2412/P mechanically compatible?
A: Both parts use a 10-SMD module with 6 leads and surface mount configuration.

Q: Does the substitute meet the same compliance standards as the original part?
A: Both parts are ROHS3 compliant and REACH unaffected.

Q: Is there any difference in thermal performance or operating temperature?
A: The substitute part offers a broader operating temperature range (-40°C to 100°C).

Q: Can the substitute part support existing inventory and manufacturing processes?
A: The substitute part is active, available in stock, and matches the required surface mount package and compliance standards.

Q: How does the efficiency and output power compare between the models?
A: Both models specify 60% efficiency and 500mW output power, meeting substitution criteria.
