Equivalent & Substitute Parts for RAC04-24SA/277

Part Overview

The RAC04-24SA/277 by Recom Power is an enclosed AC/DC converter supplying a single 24V output at up to 167mA with a universal 90~305VAC input, outputting 4W of power. It is designed for ITE (commercial) applications, features universal input, and is housed in a 7-DIP module with through-hole mounting. This product is classified as obsolete, which requires engineers to identify and qualify suitable equivalent or substitute models with matching or better key electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution in the AC/DC converter product category is governed by the following critical criteria:

• Voltage - Output 1 must match (24V)
• Power rating must meet or exceed (4W)
• Maximum output current must match (167mA)
• Input voltage range must cover 90~305VAC
• Mechanical compatibility: mounting type, and package dimensions
• Certifications and RoHS/REACH compliance
• Number of outputs (1)
• Application suitability as specified

These allowed parameters are used to determine and justify valid substitute part numbers for RAC04-24SA/277.

Parameter Comparison

Engineering Selection Recommendations

RAC04-24SK/277 is active and ROHS3/REACH compliant, and covers or exceeds the temperature, efficiency, and input voltage range of the obsolete RAC04-24SA/277. It also carries relevant certifications (CB, CE, cURus) and provides mechanical compatibility for through-hole mounting.

RAC04-24SC/277, though not for new designs, is a valid substitute based on matching electrical and mechanical characteristics, RoHS and REACH compliance, and standard industry approvals (CE, EN, UL).

Selection between these direct and similar substitutes should be guided by the current product status, required certifications, and confirmed mechanical compatibility based solely on provided data.

Frequently Asked Questions (FAQ)

Q: What key parameters determine valid substitution among RAC04-24SA/277, RAC04-24SK/277, and RAC04-24SC/277?
A: Output voltage (24V), output current (167mA), output power (4W), input voltage range, mounting type, package size, number of outputs, and compliance/certification status.

Q: Are the substitute parts compatible in terms of mounting and mechanical layout?
A: All listed parts are through-hole modules with comparable package sizes; mechanical compatibility should be verified against the provided dimensions and DIP configuration.

Q: Do substitute models meet the same compliance and safety requirements?
A: All parts are ROHS3 compliant and REACH unaffected. Approval agencies are listed for each, and should be cross-checked against application requirements.

Q: Is there any difference in environmental ratings among the substitutes?
A: Operating temperature ranges differ: RAC04-24SK/277 supports up to 90°C, RAC04-24SC/277 up to 80°C, and RAC04-24SA/277 up to 70°C. This may impact selection where operating temperature is critical.

Q: Which substitute is recommended if ongoing availability is required?
A: RAC04-24SK/277 is active and available, as described, whereas RAC04-24SC/277 is not for new designs and RAC04-24SA/277 is obsolete.

Q: Is package orientation and pin count identical for all options?
A: RAC04-24SA/277 and RAC04-24SC/277 are both 7-DIP module, 6 leads. RAC04-24SK/277 is 6-DIP module; dimensional data is provided for selection.
