Equivalent & Substitute Parts for SPB03C-15 DC DC Converter

Part Overview

The SPB03C-15, manufactured by MEAN WELL USA Inc., is an isolated module DC DC converter designed for 1 output at 15V and 200mA, with a 36V–72V input range and 3W output power. This model is now listed as "Obsolete," making it necessary to identify alternative parts that match its specified function and key parameters. Substitution ensures continued system compatibility and compliance, given that the main part is no longer available as new stock.

Key Parameters

Substitute Part Grouping Explanation

Substitution selection is strictly determined by electrical and mechanical compatibility across the following explicitly detailed parameters: input voltage range, output voltage, output current, total power, isolation voltage, number of outputs, application category, feature set, operating temperature, mounting type, package dimensions, regulatory compliance, and moisture sensitivity level. Only substitute parts meeting all these defined parameters are included for direct replacement consideration.

Parameter Comparison

Engineering Selection Recommendations

Replacement selection based on product status prioritizes substitutes that are active and available, such as RS3-4815S. Compliance with ROHS3, REACH, ECCN EAR99, and an unlimited moisture sensitivity level (MSL 1) is maintained. Package, mounting, and dimensional attributes also match the original, supporting direct component interchange within regulated and environmentally compliant applications.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match for direct substitution of SPB03C-15?

• Substitution requires identical input voltage range, output voltage, current output, power rating, isolation voltage, number of outputs, application category, mounting type, package dimensions, and compliance data.

Q2: Are there differences in package or mounting type between SPB03C-15 and RS3-4815S?

• Both SPB03C-15 and RS3-4815S use the 8-SIP Module, 7 Leads package and are through hole mountable. Size and dimensions are identical.

Q3: Do all compliance and certification attributes align between SPB03C-15 and RS3-4815S?

• Both parts are listed as ROHS3 Compliant, REACH Unaffected, ECCN EAR99, and have an unlimited moisture sensitivity level.

Q4: Is there any difference in operating temperature or efficiency between the parts?

• SPB03C-15 operates from -40°C to 85°C (with derating), while RS3-4815S operates from -40°C to 71°C. The efficiency of RS3-4815S is 83%, compared to 82% for SPB03C-15.

Q5: Is feature compatibility taken into account for substitution?

• Feature sets are matched strictly per input data. RS3-4815S provides Remote On/Off and SCP, whereas SPB03C-15 provides Remote On/Off, OCP, and SCP. Differences are explicitly noted.
