RAC04-24SA AC/DC Converter Equivalent & Substitute Parts

Part Overview

The RAC04-24SA is an enclosed AC/DC converter from Recom Power's POWERLINE RAC04 series, rated for 4W output power with a single 24V output at 167mA maximum current. This component is designed for ITE (Commercial) applications with universal input voltage range of 90–264 VAC and operates across -40°C to 70°C with derating.

The RAC04-24SA carries a "Not For New Designs" product status designation. This status indicates that while the part remains available in inventory, Recom Power has discontinued active development and support for this series. Organizations requiring this converter for new product development or long-term deployment must evaluate equivalent substitute parts to ensure design continuity and future component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RAC04-24SA is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Single output configuration with 24V output voltage
• Maximum output current of 167mA
• 4W power rating
• Through-hole mounting type with 7-DIP module package

Input Voltage Compatibility: The RAC04-24SA operates with a 90–264 VAC input range. Substitute parts must support this input specification or a broader range that encompasses these limits.

Mechanical Compatibility: The 7-DIP module package and through-hole mounting type define the physical footprint. Substitute parts must maintain identical or compatible package geometry to ensure PCB layout compatibility.

Regulatory and Compliance Alignment: All substitute parts must maintain ROHS3 compliance and equivalent safety certifications (CE, EN, UL/cULus) to satisfy procurement and deployment requirements.

The RAC04-24SC/277 qualifies as a direct substitute based on matching output specifications (24V, 167mA, 4W), identical package type (7-DIP module), and through-hole mounting configuration. The substitute extends the input voltage range to 80–305 VAC, providing broader operational flexibility while maintaining all required certifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in Existing Designs:

The RAC04-24SC/277 serves as a direct electrical and mechanical substitute for the RAC04-24SA. Both parts share identical output specifications (24V, 167mA, 4W), package configuration (7-DIP module, through-hole mounting), and regulatory compliance status (ROHS3, CE, EN, UL certifications).

Operational Advantages of the Substitute:

The RAC04-24SC/277 extends the input voltage operating range from 90–264 VAC to 80–305 VAC, accommodating broader international power supply variations. The substitute also provides improved thermal performance with an extended operating temperature range (-25°C to 80°C versus -40°C to 70°C) and higher efficiency (79% versus 77%).

Compliance Considerations:

Both parts carry "Not For New Designs" status from Recom Power. This designation applies equally to the original and substitute. Organizations planning new product development should evaluate current-generation converter solutions from Recom Power or alternative manufacturers to ensure long-term component availability and manufacturer support.

Packaging and Inventory:

The RAC04-24SA is supplied in box packaging with 1,106 units in stock. The RAC04-24SC/277 is supplied in tube packaging with 3,174 units in stock. Packaging format does not affect electrical or mechanical compatibility; selection depends on procurement volume and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the RAC04-24SC/277 replace the RAC04-24SA in existing circuit designs?

A: Yes. The RAC04-24SC/277 is electrically and mechanically compatible with the RAC04-24SA. Both converters deliver 24V at 167mA maximum output current with identical 7-DIP module package geometry and through-hole mounting configuration. PCB layouts designed for the RAC04-24SA accommodate the RAC04-24SC/277 without modification.

Q: What are the key differences between these two parts?

A: The primary differences are input voltage range, operating temperature range, and efficiency. The RAC04-24SC/277 accepts 80–305 VAC input (versus 90–264 VAC for the RAC04-24SA), operates to 80°C maximum (versus 70°C), and achieves 79% efficiency (versus 77%). Line regulation is ±2% for the substitute compared to ±0.2% for the original.

Q: Are both parts suitable for new product designs?

A: No. Both the RAC04-24SA and RAC04-24SC/277 carry "Not For New Designs" status. This designation indicates that Recom Power has discontinued active development for these models. New designs should incorporate current-generation converter solutions to ensure manufacturer support and long-term component availability.

Q: Do the different packaging formats (box versus tube) affect compatibility?

A: No. Packaging format (box for RAC04-24SA, tube for RAC04-24SC/277) is a supply and handling consideration only. It does not affect electrical performance, mechanical fit, or functional compatibility. Selection between box and tube packaging depends on procurement volume and assembly process requirements.

Q: What certifications apply to both converters?

A: Both parts hold CE, EN, and UL certifications under standard EN 60950-1 (ITE safety). Both are ROHS3 compliant and REACH unaffected. Certification equivalence ensures regulatory compliance across markets requiring these safety standards.

Q: Can the RAC04-24SC/277 operate in the full -40°C to 70°C range of the original?

A: The RAC04-24SC/277 operates from -25°C to 80°C with derating. This range does not extend to -40°C. Applications requiring operation below -25°C must retain the RAC04-24SA or identify alternative converters with extended low-temperature specifications.

Q: How do the line regulation specifications compare?

A: The RAC04-24SA provides ±0.2% line regulation, while the RAC04-24SC/277 provides ±2% line regulation. Applications requiring tight output voltage stability across input voltage variations should retain the RAC04-24SA. The substitute is suitable for applications with standard line regulation tolerance requirements.
