Substitute Part Grouping Explanation
Substitution of the obsolete RAC01-12SC is based on the following criteria:
Output Voltage Compatibility: The substitute must provide 12V output to maintain circuit compatibility.
Package and Mounting: The substitute must use 4-DIP Module packaging with through-hole mounting to ensure PCB footprint compatibility.
Input Voltage Range: The substitute input range must encompass or exceed the original 80–264 VAC specification to support the same AC mains environments.
Current and Power Rating: The substitute must deliver equal or greater maximum output current and power rating to support the same or higher load requirements.
Regulatory Compliance: The substitute must maintain ROHS3 compliance and hold relevant safety certifications (CE, UL, or equivalent).
Product Status: Active product status ensures ongoing availability and manufacturer support.
The RAC02E-12SK/277 meets all substitution criteria as an active product with compatible output voltage, package type, enhanced input range, higher power rating, and current capacity.

Engineering Selection Recommendations
The RAC02E-12SK/277 is the qualified substitute for the obsolete RAC01-12SC based on the following engineering factors:
Product Availability: The RAC02E-12SK/277 holds active product status with 1092 units in stock, ensuring supply continuity for the discontinued RAC01-12SC.
Regulatory Compliance: Both parts maintain ROHS3 compliance and hold CE certification. The substitute carries additional certifications (CB, cURus, EAC) that expand its applicability across broader regulatory jurisdictions.
Electrical Compatibility: The substitute provides identical 12V output voltage and 4-DIP Module packaging with through-hole mounting, ensuring direct PCB compatibility without layout modifications.
Performance Enhancement: The RAC02E-12SK/277 delivers doubled power capacity (2W versus 1W) and doubled maximum output current (167mA versus 83mA), providing design margin for existing and future load requirements.
Input Range Expansion: The substitute accepts 85–305 VAC input, covering the original 80–264 VAC range with extended upper tolerance. Additional DC input capability (120–430 VDC) enables use in applications beyond the original AC-only specification.
Thermal and Regulatory Performance: The substitute operates across a wider temperature range (−40°C to +90°C versus −25°C to +85°C) and demonstrates improved line and load regulation characteristics.
Frequently Asked Questions (FAQ)
Q: Can the RAC02E-12SK/277 replace the RAC01-12SC in existing designs without PCB modifications?
A: Yes. Both parts use identical 4-DIP Module packaging with through-hole mounting. Pin-to-pin compatibility and footprint alignment are maintained, eliminating the need for PCB layout changes.
Q: What is the primary reason for substitution?
A: The RAC01-12SC is classified as obsolete. The RAC02E-12SK/277 is an active product from the same manufacturer with compatible electrical and mechanical specifications, ensuring continued supply and support.
Q: Does the higher power rating of the RAC02E-12SK/277 create any compatibility issues?
A: No. The substitute's 2W rating and 167mA maximum output current exceed the original 1W and 83mA specifications. Circuits designed for the lower-rated original part operate within the substitute's specifications without modification.
Q: Are the output voltage specifications identical?
A: Yes. Both parts provide 12V output voltage. Load and line regulation characteristics differ, with the substitute offering tighter regulation (±0.5% line regulation versus ±2%, and 0.5% load regulation versus ±6%).
Q: What certifications does the substitute hold?
A: The RAC02E-12SK/277 holds CB, CE, cURus, and EAC certifications. The original RAC01-12SC held CE, EN, and UL certifications. Both maintain ROHS3 compliance.
Q: Is the input voltage range compatible?
A: Yes. The substitute's 85–305 VAC input range encompasses the original 80–264 VAC specification. The substitute also adds DC input capability (120–430 VDC), which the original part does not support.
Q: What is the temperature operating range difference?
A: The substitute operates from −40°C to +90°C, compared to the original −25°C to +85°C. This provides extended low-temperature operation and slightly higher maximum operating temperature.
Q: Are both parts RoHS compliant?
A: Yes. Both the RAC01-12SC and RAC02E-12SK/277 are ROHS3 compliant and REACH unaffected.
