SCW05C-15 Equivalent & Substitute Parts

Part Overview

The SCW05C-15 is an isolated module DC-DC converter manufactured by MEAN WELL USA Inc., designed to convert 36V to 72V input to a regulated 15V output at 400mA maximum current. This 6W converter features integrated overcurrent protection (OCP) and short-circuit protection (SCP) with 1 kV isolation voltage, suitable for commercial ITE applications.

The SCW05C-15 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and access components with improved specifications or active manufacturing status.

• Output voltage fixed at 15V
• Output current capacity meets or exceeds 400mA
• Power rating of 6W
• Isolation voltage meets or exceeds 1 kV minimum requirement
• Protection features include OCP and SCP at minimum

Mechanical Compatibility Criteria:

• Package type: 24-DIP Module, 8 Leads
• Mounting type: Through Hole
• Physical dimensions compatible with 1.25" L x 0.80" W footprint
• MSL rating of 1 (Unlimited moisture sensitivity)

Regulatory Compliance Criteria:

• RoHS3 Compliant status
• REACH Unaffected status
• ECCN EAR99 classification

Parts meeting all electrical, mechanical, and regulatory criteria are classified as direct substitutes. Parts with enhanced specifications (higher isolation voltage, improved efficiency, extended temperature range, or active product status) are presented as qualified alternatives.

Engineering Selection Recommendations

SCWN06C-15 (MEAN WELL USA Inc.)

The SCWN06C-15 is the primary substitute for the obsolete SCW05C-15. Both converters are manufactured by MEAN WELL USA Inc. and share identical electrical specifications for input voltage range (36V to 72V), output voltage (15V), output current (400mA), and power rating (6W). The SCWN06C-15 maintains full mechanical compatibility with the same 24-DIP package and through-hole mounting configuration.

The SCWN06C-15 offers enhanced performance characteristics: isolation voltage increased to 3 kV (versus 1 kV), efficiency improved to 86% (versus 81%), and operating temperature range extended to -40°C to 90°C (versus -40°C to 71°C). The addition of UVLO (Under-Voltage Lock-Out) protection provides enhanced circuit protection. The SCWN06C-15 carries active product status with current manufacturing availability.

DH06S4815A (Delta Electronics)

The DH06S4815A is a qualified alternative substitute manufactured by Delta Electronics. This converter meets all electrical compatibility requirements with input voltage range of 36V to 75V, output voltage of 15V, output current of 400mA, and 6W power rating. Mechanical compatibility is confirmed through identical 24-DIP package and through-hole mounting.

The DH06S4815A provides isolation voltage of 1.5 kV (exceeding the 1 kV minimum), efficiency of 84%, and operating temperature range of -40°C to 85°C. UVLO protection is included. The converter carries active product status. The maximum input voltage specification of 75V (versus 72V) provides extended input range capability. This part is suitable for applications where cross-manufacturer sourcing is acceptable and Delta Electronics supply chain access is available.

Frequently Asked Questions (FAQ)

Q: Can the SCWN06C-15 be used as a direct replacement for the SCW05C-15?

A: Yes. The SCWN06C-15 is a direct substitute. Both parts share identical input voltage range (36V to 72V), output voltage (15V), output current (400mA), power rating (6W), package type (24-DIP Module, 8 Leads), and through-hole mounting. The SCWN06C-15 provides enhanced specifications including higher isolation voltage (3 kV versus 1 kV), improved efficiency (86% versus 81%), and extended operating temperature range (-40°C to 90°C versus -40°C to 71°C).

Q: What are the physical dimension differences between these parts?

A: The SCW05C-15 has a height of 12.2mm (1.25" L x 0.80" W x 0.48" H). Both the SCWN06C-15 and DH06S4815A have a reduced height of 10.2mm (1.25" L x 0.80" W x 0.40" H). The length and width dimensions remain identical across all three parts. This dimensional reduction may provide improved PCB layout flexibility in space-constrained applications.

Q: Are there isolation voltage differences that affect circuit design?

A: Yes. The SCW05C-15 provides 1 kV isolation. The SCWN06C-15 provides 3 kV isolation, and the DH06S4815A provides 1.5 kV isolation. If the original design requires only 1 kV isolation, both substitutes exceed this requirement and are compatible. If higher isolation voltage is required by system specifications, the SCWN06C-15 with 3 kV isolation is the optimal choice.

Q: What protection features are included in each converter?

A: The SCW05C-15 includes OCP (Overcurrent Protection) and SCP (Short-Circuit Protection). The SCWN06C-15 and DH06S4815A both include OCP, SCP, and UVLO (Under-Voltage Lock-Out). UVLO provides additional circuit protection by disabling the converter output when input voltage falls below a specified threshold.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. All three converters are ROHS3 Compliant and REACH Unaffected. All parts carry MSL rating of 1 (Unlimited moisture sensitivity), indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the efficiency difference between these converters?

A: The SCW05C-15 operates at 81% efficiency. The SCWN06C-15 achieves 86% efficiency, and the DH06S4815A achieves 84% efficiency. Higher efficiency reduces heat dissipation and improves overall system power consumption, particularly in applications with continuous or high-duty-cycle operation.

Q: Can the DH06S4815A be used in place of the SCW05C-15?

A: Yes. The DH06S4815A is a qualified substitute meeting all electrical and mechanical compatibility criteria. The maximum input voltage specification of 75V (versus 72V) provides extended input range capability. This part is suitable when cross-manufacturer sourcing is acceptable and Delta Electronics supply chain access is available.

Q: What is the operating temperature range difference?

A: The SCW05C-15 operates from -40°C to 71°C. The SCWN06C-15 extends this range to -40°C to 90°C, and the DH06S4815A operates from -40°C to 85°C. Extended temperature range capability is beneficial for applications in elevated ambient temperature environments or systems with significant internal heat generation.
