RAC01-05SC Equivalent & Substitute Parts

Part Overview

The RAC01-05SC is an enclosed AC/DC converter from Recom Power's POWERLINE RAC01-C series, rated for 1W output power with a single 5V output at 200mA maximum current. This module accepts 80 to 264 VAC input and is designed for ITE (Commercial) applications with short-circuit protection (SCP) features.

The RAC01-05SC is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this converter.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RAC01-05SC is determined by the following critical parameters:

Output Voltage Compatibility: The substitute part must provide 5V output to maintain circuit compatibility.

Output Current Capacity: The substitute must deliver at least 200mA maximum output current to support the original design load requirements.

Input Voltage Range: The substitute must accept the same or broader input voltage range (80 ~ 264 VAC minimum).

Package and Mounting: The substitute must use the same 4-DIP Module package with through-hole mounting to ensure mechanical and electrical compatibility with existing PCB layouts.

Regulatory Compliance: The substitute must maintain ROHS3 compliance and hold appropriate safety certifications (CE, UL, or equivalent).

The RAC02E-05SK/277 meets these substitution criteria by providing 5V output at 400mA (exceeding the 200mA requirement), accepting a broader input range (85 ~ 305 VAC, 120 ~ 430 VDC), maintaining the 4-DIP Module package format, and holding active product status with current regulatory compliance.

Engineering Selection Recommendations

The RAC02E-05SK/277 is the qualified substitute for the obsolete RAC01-05SC based on the following engineering criteria:

Regulatory and Compliance Status: The RAC02E-05SK/277 holds active product status with current certifications (CB, CE, cURus, EAC), ensuring ongoing manufacturer support and compliance with current standards. The RAC01-05SC, being obsolete, no longer receives manufacturer updates or support.

Output Specifications: Both parts deliver 5V output with identical voltage regulation. The RAC02E-05SK/277 provides 400mA output current, which exceeds the RAC01-05SC's 200mA specification, ensuring full compatibility with existing load requirements.

Input Voltage Compatibility: The RAC02E-05SK/277 accepts 85 ~ 305 VAC input, which encompasses the RAC01-05SC's 80 ~ 264 VAC range with extended upper tolerance. The substitute also accepts 120 ~ 430 VDC input, providing additional flexibility for DC-powered applications.

Physical and Electrical Interface: Both parts use identical 4-DIP Module packaging with through-hole mounting, ensuring direct PCB compatibility without layout modifications.

Performance Characteristics: The RAC02E-05SK/277 demonstrates improved efficiency (72% versus 68%), superior line regulation (±0.5% versus ±2%), and superior load regulation (0.5% versus ±6%), providing enhanced system stability and reduced thermal dissipation.

Environmental Operating Range: The RAC02E-05SK/277 extends the lower operating temperature limit to -40°C and upper limit to 90°C, compared to the RAC01-05SC's -25°C to 85°C range, supporting broader application environments.

Frequently Asked Questions (FAQ)

Q: Can the RAC02E-05SK/277 directly replace the RAC01-05SC without PCB modifications?

A: Yes. Both parts use the 4-DIP Module package with identical through-hole mounting configuration and pinout compatibility. No PCB layout changes are required for mechanical or electrical integration.

Q: What is the significance of the higher 400mA output current on the RAC02E-05SK/277?

A: The RAC02E-05SK/277 provides 400mA maximum output current, which is double the RAC01-05SC's 200mA specification. This ensures the substitute can support the original design's 200mA load requirement with additional headroom for future design margin or load expansion.

Q: Are there input voltage range differences that affect system design?

A: The RAC02E-05SK/277 accepts 85 ~ 305 VAC input, which overlaps the RAC01-05SC's 80 ~ 264 VAC range. The substitute's lower limit is 5V higher and upper limit is 41V higher. For systems operating within 85 ~ 264 VAC, both parts are compatible. The RAC02E-05SK/277 also accepts 120 ~ 430 VDC input, enabling use in DC-powered applications where the original part cannot be used.

Q: What regulatory certifications apply to the substitute part?

A: The RAC02E-05SK/277 holds CB, CE, cURus, and EAC certifications. The original RAC01-05SC held CE, EN, and UL certifications. Both parts maintain ROHS3 compliance and REACH unaffected status. Verify that the substitute's certification set meets your specific application and regional requirements.

Q: How do the regulation specifications differ between these parts?

A: The RAC02E-05SK/277 provides superior line regulation (±0.5% versus ±2%) and load regulation (0.5% versus ±6%). These improvements result in more stable output voltage across varying input and load conditions, reducing output voltage variation in the system.

Q: Is the RAC02E-05SK/277 available in the same packaging format?

A: Yes. Both parts use 4-DIP Module packaging. The RAC02E-05SK/277 dimensions are 1.33" L x 0.87" W x 0.61" H, compared to the RAC01-05SC's 1.33" L x 0.87" W x 0.71" H. The height difference of 0.10" (2.6mm) is negligible for most PCB layouts and does not affect mounting compatibility.

Q: What is the operational temperature range difference?

A: The RAC02E-05SK/277 operates from -40°C to 90°C with derating, compared to the RAC01-05SC's -25°C to 85°C range. The substitute provides 15°C additional lower temperature capability and 5°C additional upper temperature capability, supporting applications in more extreme thermal environments.

Q: Why is the RAC01-05SC classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support for this part. The RAC02E-05SK/277 is the active replacement, ensuring continued availability, manufacturer technical support, and compliance with current regulatory standards.
