Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on the following key parameters: input voltage range (18V–36V), output voltage (5V), output current (600mA max), power rating (3 W), isolation rating, features (OCP, SCP), mounting type (Through Hole), package (24-DIP Module, 8 Leads), application (ITE Commercial), RoHS/REACH compliance, and MSL. Only components matching these characteristics or exceeding their ratings are listed as alternatives.

Parameter Comparison

Engineering Selection Recommendations

Product status is a primary selection factor. SCW03B-05 is obsolete; substitutes with active status, such as SCWN03B-05 (MEAN WELL USA Inc.) and REC3-2405SRWZ/H4/A (Recom Power), meet relevant compliance requirements (RoHS3, REACH, MSL 1) and match or exceed key electrical and mechanical parameters. Both substitutes fall within the specified input voltage, output voltage and current, package, and compliance characteristics.

Frequently Asked Questions (FAQ)

Q1: Which parameters are essential for substituting SCW03B-05?
A1: Input voltage range, output voltage, output current, power rating, isolation voltage, package type, mounting type, features (OCP, SCP), application classification, RoHS and REACH compliance, as well as MSL.

Q2: Are the substitutes compatible with the same PCB footprint as SCW03B-05?
A2: All parts use the 24-DIP Module, 8 Leads form factor with through-hole mounting, supporting mechanical compatibility.

Q3: Is there a difference in regulatory or hazardous substance compliance among the options?
A3: All listed parts are ROHS3 compliant, REACH unaffected, and rated MSL 1 (Unlimited).

Q4: What is the difference between the substitutes in terms of isolation voltage?
A4: SCWN03B-05 provides 3 kV isolation, REC3-2405SRWZ/H4/A provides 4 kV, both exceeding the original 1 kV rating of SCW03B-05.

Q5: Are features such as OCP and SCP available in all substitutes?
A5: OCP and SCP are present in the SCWN03B-05. REC3-2405SRWZ/H4/A offers SCP.

Q6: Can these substitutes operate in similar or broader temperature ranges?
A6: Yes, both alternatives support a wider operating temperature range compared to SCW03B-05.

Q7: Do all options belong to the same product category?
A7: All are categorized as isolated module DC-DC converters with the specified electrical and mechanical parameters.
