RAC40-12SB Equivalent & Substitute Parts Reference
Part Overview
The Recom Power RAC40-12SB is an AC/DC converter designed for ITE (Commercial) applications, providing a single 12V output at up to 3.33A with a total power rating of 40W. The module features a universal input voltage range and is mounted via through-hole. This product is now listed as obsolete, making it necessary to identify strictly equivalent alternative models based on electrical, mechanical, and regulatory compatibility for continued design, maintenance, or replacement purposes.

Substitute Part Grouping Explanation
Substitution is determined strictly by matching or exceeding electrical parameters (output voltage, output current, input voltage range, power rating), form factor (mounting type, package/case, size/dimension), and regulatory compliance (RoHS status, approval agencies, standard number, moisture sensitivity, and REACH status). Compatible substitutes must meet or exceed all these key parameters to ensure functional and regulatory equivalence in application.

Engineering Selection Recommendations
Selection is based on the product status, which is obsolete for the RAC40-12SB and active for the RACM40-12SK-T. Both parts are ROHS3 compliant and have REACH Unaffected status. Approvals for RACM40-12SK-T exceed those of RAC40-12SB, including CE certification. Only substitute parts listed with complete compliance and relevant certifications are aligned for consideration.
Frequently Asked Questions (FAQ)
Q: Which parameters must match when selecting a substitute for the RAC40-12SB?
A: Output voltage, maximum output current, total output power, input voltage range, mounting type, package/case, regulatory compliance, and environmental certifications must align.
Q: Are differences in package or size between the RAC40-12SB and RACM40-12SK-T critical?
A: Substitute selection includes package type and mounting style. Variations in dimensions or pin count may require evaluation of physical PCB compatibility.
Q: Does the substitute part RACM40-12SK-T maintain regulatory approvals and compliance?
A: The RACM40-12SK-T includes CE certification, as well as additional approvals. Both parts are ROHS3 compliant and have REACH Unaffected status.
Q: Can I use RACM40-12SK-T as a direct replacement in all electrical and regulatory respects?
A: Electrical parameters (output voltage, current, power), compliance, and mounting method are provided and align with substitution requirements as per the input parameters.
Q: Are the operational temperature and environmental ratings compatible?
A: The provided parameters show both parts operate from -40°C with derating, meeting environmental requirements for substitution.
