SPB03A-05 Equivalent & Substitute Parts Reference

Part Overview

The SPB03A-05, manufactured by MEAN WELL USA Inc., is an isolated DC-DC converter module featuring a single 5V output at up to 600mA and rated for 3W total output power. It provides 1 kV isolation, remote on/off control, over-current and over-temperature protection, and is housed in an 8-SIP module through-hole package. This part is currently classified as obsolete, necessitating the identification of suitable alternatives that match the key operational and mechanical parameters for continued system compatibility or new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the SPB03A-05 are selected strictly by matching the following key electrical, mechanical, and regulatory parameters: function (isolated DC-DC converter module), number of outputs, output voltage and current, power rating, isolation voltage, package/case format, mounting type, ITE application suitability, remote on/off feature, RoHS/REACH compliance status, and control features. Compliance with product safety and regulatory requirements is maintained. Only parts with corresponding specifications for these listed parameters are included.

Parameter Comparison

Engineering Selection Recommendations

The SPB03A-05 is labeled as obsolete. The RS3-0505S DC DC converter from Recom Power is in active status and maintains both ROHS3 and REACH compliance, with matching isolation, output voltage, output current, mechanical form factor, and other listed regulatory identifiers. The RS3-0505S provides the required certification coverage and package compatibility, meeting selection criteria strictly based on product status and provided compliance certifications.

Frequently Asked Questions (FAQ)

Q1: What are the primary substitution criteria for DC-DC converter modules like SPB03A-05?
A1: Key criteria include matching output voltage, output current, power rating, number of outputs, isolation voltage, mechanical package/case type, mounting method, application suitability, features, and regulatory compliance.

Q2: Is the RS3-0505S a direct fit mechanical replacement for SPB03A-05?
A2: Both parts use an 8-SIP module with 7 leads and have identical physical dimensions, supporting direct through-hole mounting compatibility.

Q3: Are there any notable differences in control or protection features?
A3: Both parts offer remote on/off control and short-circuit protection. The SPB03A-05 also lists over-current protection.

Q4: Is there a difference in operating temperature range?
A4: The SPB03A-05 operates from -40°C to 85°C (with derating), while the RS3-0505S is specified for -40°C to 71°C.

Q5: What compliance certifications do both models hold?
A5: Both modules are ROHS3 compliant, REACH unaffected, and have MSL 1 (unlimited) rating, ECCN EAR99, and HTSUS 8504.40.9580 regulatory identifiers.

Q6: Can substitute parts be used without modification to PCB layout?
A6: When the package/case and pin-out remain consistent, such as with identical 8-SIP module, 7 leads packages, direct PCB replacement is supported.
