SPA02E-05 Equivalent & Substitute Parts

Part Overview

The SPA02E-05 is an isolated module DC-DC converter manufactured by MEAN WELL USA Inc., designed to convert input voltages between 4.5V and 9V to a regulated 5V output at 400mA maximum current. This 2W converter features remote on/off control, output current protection (OCP), and short circuit protection (SCP), with 1 kV isolation suitable for ITE commercial applications.

The SPA02E-05 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this converter.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SPA02E-05 are identified based on strict electrical and mechanical compatibility criteria. All substitute candidates must satisfy the following parameters:

Mandatory Matching Parameters:

• Input voltage range: 4.5V to 9V
• Output voltage: 5V
• Output current capacity: 400mA minimum
• Power rating: 2W
• Package type: 8-SIP Module, 7 Leads
• Physical dimensions: 0.86" L x 0.36" W x 0.44" H
• Mounting type: Through Hole
• Operating temperature range: -40°C to 85°C minimum
• RoHS3 compliance

Acceptable Variation Parameters:

• Isolation voltage: Equal to or greater than 1 kV
• Efficiency: May vary
• Protection features: May include additional features beyond OCP and SCP

Substitutes are grouped into two categories: direct manufacturer equivalents and compatible alternatives from other manufacturers meeting all electrical and mechanical specifications.

Engineering Selection Recommendations

SPAN02E-05 (Direct Equivalent)

The SPAN02E-05 is the direct manufacturer equivalent from MEAN WELL USA Inc. This part maintains identical electrical specifications and package configuration to the SPA02E-05. Selection of this part is appropriate for applications requiring continuity with the original design without modification. The SPAN02E-05 provides the most direct substitution path for existing designs.

RS-0505S/H3 (Compatible Alternative)

The RS-0505S/H3 from Recom Power is a compatible alternative that meets all mandatory electrical and mechanical parameters. This part offers enhanced isolation voltage (3 kV versus 1 kV), improved efficiency (75% versus 71%), and active product status. The RS-0505S/H3 is suitable for applications where the original SPA02E-05 is unavailable and where the enhanced isolation specification does not create design conflicts. Both parts are ROHS3 compliant and share identical package dimensions and mounting characteristics.

Selection between these substitutes depends on supply availability, cost considerations, and whether the enhanced isolation voltage of the RS-0505S/H3 is compatible with the target application.

Frequently Asked Questions (FAQ)

Q: Can the SPAN02E-05 be used as a direct replacement for the SPA02E-05?

A: Yes. The SPAN02E-05 is the direct manufacturer equivalent and maintains identical electrical specifications, output ratings, input voltage range, package type, and physical dimensions. No design modifications are required.

Q: What are the key differences between the SPA02E-05 and RS-0505S/H3?

A: Both parts share identical input voltage range (4.5V to 9V), output voltage (5V), output current (400mA), power rating (2W), package type (8-SIP Module, 7 Leads), physical dimensions, and operating temperature range. The RS-0505S/H3 provides higher isolation voltage (3 kV versus 1 kV) and improved efficiency (75% versus 71%). The RS-0505S/H3 is currently in active production status.

Q: Are the physical dimensions identical across all three parts?

A: The SPA02E-05 and RS-0505S/H3 share identical dimensions of 0.86" L x 0.36" W x 0.44" H (21.8mm x 9.2mm x 11.1mm). Physical dimensions for the SPAN02E-05 are not specified in available documentation.

Q: Can the RS-0505S/H3 be used in applications originally designed for the SPA02E-05?

A: The RS-0505S/H3 meets all mandatory electrical and mechanical specifications of the SPA02E-05. The higher isolation voltage (3 kV) is compatible with applications requiring 1 kV isolation. Verification of PCB layout compatibility and connector pin assignment is necessary prior to implementation.

Q: What is the difference in protection features between these parts?

A: The SPA02E-05 includes remote on/off control, output current protection (OCP), and short circuit protection (SCP). The RS-0505S/H3 includes remote on/off control and short circuit protection (SCP), with enable control and active low logic. The RS-0505S/H3 does not specify OCP functionality.

Q: Are all three parts RoHS3 compliant?

A: The SPA02E-05 and RS-0505S/H3 are confirmed ROHS3 compliant. RoHS status for the SPAN02E-05 is not specified in available documentation.

Q: What is the moisture sensitivity level for these converters?

A: Both the SPA02E-05 and RS-0505S/H3 have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
