RB-0505D/H Equivalent & Substitute Parts

Part Overview

The RB-0505D/H is an isolated module DC-DC converter manufactured by Recom Power, part of the ECONOLINE RB (1W) series. This component provides dual output voltage rails (+5V and -5V) from a single 4.5V to 5.5V input, delivering 100mA on each output with 1W total power capacity. The device is classified as an active product with current inventory of 12,400 pieces in stock.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative sourcing while maintaining electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RB-0505D/H are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for a part to function as a direct substitute:

Critical Matching Parameters:

• Input voltage range: 4.5V to 5.5V
• Output voltage configuration: +5V and -5V dual output
• Output current capacity: minimum 100mA per rail
• Total power rating: 1W
• Package type: 7-SIP Module, 5 Leads
• Physical dimensions: 19.7mm × 6.0mm × 10.2mm
• Mounting method: Through Hole

Acceptable Variation Parameters:

• Isolation voltage: minimum 2 kV (higher values acceptable)
• Operating temperature range: minimum -40°C to 85°C (extended ranges acceptable)
• Efficiency: variations acceptable within product category norms
• Compliance certifications: variations acceptable if meeting regional requirements

The E0505S-1WR3 manufactured by Mornsun America, LLC meets all critical matching parameters and qualifies as a direct substitute for the RB-0505D/H.

Engineering Selection Recommendations

Primary Selection: RB-0505D/H (Recom Power)

The RB-0505D/H is the specified component with active product status and substantial inventory availability (12,400 pieces). This part carries ROHS3 compliance certification and is suitable for ITE (Commercial) and Medical applications as documented in the product specifications.

Alternative Selection: E0505S-1WR3 (Mornsun America, LLC)

The E0505S-1WR3 qualifies as a direct substitute when RB-0505D/H availability is constrained. This part demonstrates:

• Identical electrical performance across all critical parameters
• Enhanced isolation voltage (3 kV versus 2 kV minimum)
• Extended operating temperature range (-40°C to 105°C with derating)
• Improved efficiency (82% versus 78%)
• Active product status with 2,450 pieces in current inventory
• RoHS compliance and REACH unaffected status
• Identical physical footprint and through-hole mounting configuration
• Regulatory certifications: CB, CE, cURus

Both components share identical ECCN (EAR99) and HTSUS (8504.40.9580) classifications, ensuring equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the E0505S-1WR3 be used as a direct replacement for the RB-0505D/H in existing designs?

A: Yes. The E0505S-1WR3 provides identical input voltage range, dual output voltages (+5V and -5V), output current capacity (100mA per rail), power rating (1W), package type (7-SIP Module, 5 Leads), and physical dimensions (19.7mm × 6.0mm × 10.2mm). No PCB layout modifications are required.

Q: What are the differences between these two parts?

A: The E0505S-1WR3 offers three enhancements: higher isolation voltage (3 kV versus 2 kV), extended operating temperature range (-40°C to 105°C versus -40°C to 85°C), and higher efficiency (82% versus 78%). These differences represent improvements that do not affect compatibility.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS compliant and REACH unaffected. The RB-0505D/H carries ROHS3 certification. The E0505S-1WR3 carries CB, CE, and cURus certifications. Both share identical ECCN (EAR99) and HTSUS (8504.40.9580) classifications.

Q: What is the input voltage requirement for both parts?

A: Both the RB-0505D/H and E0505S-1WR3 require an input voltage range of 4.5V to 5.5V. They are not interchangeable with converters designed for different input voltage specifications.

Q: Can these parts be used in medical applications?

A: The RB-0505D/H is explicitly listed for Medical applications. The E0505S-1WR3 is listed for ITE (Commercial) applications. Application suitability must be confirmed against specific medical device requirements and regulatory pathways.

Q: What is the maximum current available from each output?

A: Both parts deliver 100mA maximum from the +5V output and 100mA maximum from the -5V output, for a combined total of 1W power capacity.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 19.7mm length × 6.0mm width × 10.2mm height and use identical 7-SIP Module packaging with 5 leads. They are mechanically interchangeable on through-hole PCB designs.
