Equivalent & Substitute Parts Reference for SPB03B-05

Part Overview

The MEAN WELL USA Inc. SPB03B-05 is an isolated module DC DC converter delivering a regulated 5V output at 600mA from an 18V to 36V input range, rated at 3W power. Product features include remote on/off, overcurrent and short circuit protection, and 1 kV isolation, in an 8-SIP module with 7 leads. The operating temperature range is -40°C to 85°C (with derating), efficiency is 77%, and mounting is through hole. The part is classified as obsolete, making the identification of fully compatible substitute DC DC converters essential for sustaining existing designs, production, and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitutes for SPB03B-05 are identified strictly by matching the following key parameters: type (isolated module), number of outputs (1), input voltage range (18V - 36V), output voltage (5V), output current capability (600mA), power output (3W), isolation voltage (1kV), application classification (ITE Commercial), features (especially remote on/off, overcurrent and short circuit protection), operating temperature range, mounting type (through hole), package/case (8-SIP Module, 7 Leads), physical dimensions, control features (enable, active low), and compliance requirements (RoHS3, REACH).

Parameter Comparison

Engineering Selection Recommendations

The SPB03B-05 is obsolete. The substitute RS3-2405S is active and maintains compliance with ROHS3 and REACH requirements. Both modules are classified with Moisture Sensitivity Level (MSL) 1 (Unlimited). ECCN and HTSUS codes are consistent. Selection strictly on these criteria supports continued compliance and maintains supply assurance.

Frequently Asked Questions (FAQ)

Q1: What defines the compatibility of DC DC converter substitutes in this category?
Compatibility is defined by matching parameters: type, number of outputs, input voltage range, output voltage and current, output power, isolation voltage, application, control features, package/case, mounting, compliance (RoHS3, REACH), and MSL.

Q2: Are the package and mechanical dimensions consistent between SPB03B-05 and RS3-2405S?
Both use an 8-SIP Module, 7 Leads package with dimensions 0.86" L x 0.36" W x 0.44" H (21.8mm x 9.2mm x 11.1mm).

Q3: Does the RS3-2405S maintain the compliance and certification status of the original part?
RS3-2405S is ROHS3 compliant, REACH unaffected, and carries the same MSL classification as SPB03B-05.

Q4: Is there any difference in control features or functionality relevant for direct substitution?
Both parts offer enable and active low control features. Functionality is equivalent based on provided parameters.

Q5: What applications are supported by these DC DC converters?
Both SPB03B-05 and RS3-2405S support ITE (Commercial) applications.
