REC7.5-2405DRW/H2/A/M/CTRL Equivalent & Substitute Parts

Part Overview

The REC7.5-2405DRW/H2/A/M/CTRL is an isolated module DC-DC converter manufactured by Recom Power, part of the ECONOLINE REC7.5 series. This 8W converter provides dual output voltages (+5V and -5V) from an 18V to 36V input range, with a maximum output current of 750mA per rail. The unit features remote on/off control with active low enable functionality and short circuit protection (SCP). The product maintains active status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications align with the main part specifications, enabling direct replacement in applications where the original part becomes unavailable or inventory constraints require alternative sourcing.

• Dual output configuration: +5V and -5V outputs
• Output current capability: minimum 750mA per rail
• Power rating: 8W nominal
• Isolation voltage: minimum 2 kV
• Operating temperature range: -40°C to 71°C

Mechanical Compatibility Requirements:

• Package type: 24-DIP Module with 8 leads
• Mounting type: Through hole
• Physical dimensions: compatible with 1.26" L x 0.80" W x 0.41" H envelope

Compliance Requirements:

• RoHS3 compliance
• MSL 1 rating
• Active product status

The DCW08B-05 from MEAN WELL USA Inc. meets these substitution criteria across all electrical and mechanical parameters, enabling direct replacement in equivalent applications.

Engineering Selection Recommendations

Primary Part: REC7.5-2405DRW/H2/A/M/CTRL

The REC7.5-2405DRW/H2/A/M/CTRL remains the preferred selection when available. This part delivers superior isolation voltage (2 kV versus 1 kV), higher efficiency (82% versus 78%), and remote on/off control capability. Both parts maintain active manufacturing status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute Part: DCW08B-05

The DCW08B-05 serves as a direct functional substitute when the primary part is unavailable. This MEAN WELL USA Inc. component provides equivalent input/output voltage specifications and exceeds the output current requirement (800mA versus 750mA per rail). Both units share identical 24-DIP through-hole packaging, operating temperature range, and compliance certifications.

Selection Considerations:

The DCW08B-05 exhibits a 0.7mm height differential (12.2mm versus 10.5mm), which remains within typical PCB assembly tolerances for through-hole mounted components. The lower isolation voltage (1 kV) of the DCW08B-05 is suitable for non-medical applications where 2 kV isolation is not a design requirement. The DCW08B-05 requires thermal derating at elevated temperatures, whereas the REC7.5-2405DRW/H2/A/M/CTRL maintains full specifications across the operating range.

Both parts carry identical ECCN (EAR99) and HTSUS (8504.40.9580) classifications, ensuring equivalent regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can the DCW08B-05 directly replace the REC7.5-2405DRW/H2/A/M/CTRL in all applications?

A: The DCW08B-05 provides electrical and mechanical compatibility for most applications. However, applications requiring 2 kV isolation voltage must retain the REC7.5-2405DRW/H2/A/M/CTRL. Medical device applications should verify isolation requirements against specific design specifications, as the REC7.5 series is qualified for medical use while the DCW08B-05 is designated for ITE (Commercial) applications only.

Q: What is the significance of the output current difference between these parts?

A: The REC7.5-2405DRW/H2/A/M/CTRL provides 750mA per output rail, while the DCW08B-05 provides 800mA per output rail. The DCW08B-05 exceeds the minimum requirement, making it suitable for designs operating at or below 750mA per rail. Designs requiring exactly 750mA should account for the DCW08B-05's higher current capability in thermal and power dissipation calculations.

Q: How does the physical dimension difference affect PCB layout?

A: The DCW08B-05 is 0.7mm taller (12.2mm height versus 10.5mm). This dimension difference is negligible for standard through-hole PCB assemblies with typical component clearance specifications. Verify clearance in applications with height-constrained enclosures or densely populated boards.

Q: What control feature differences exist between these converters?

A: The REC7.5-2405DRW/H2/A/M/CTRL provides remote on/off control with active low enable logic. The DCW08B-05 provides output current protection (OCP) in addition to short circuit protection (SCP). Both include SCP. Applications requiring remote on/off functionality must use the REC7.5-2405DRW/H2/A/M/CTRL.

Q: Are both parts suitable for the full -40°C to 71°C operating temperature range?

A: The REC7.5-2405DRW/H2/A/M/CTRL maintains full specifications across -40°C to 71°C. The DCW08B-05 operates within this range but requires thermal derating at elevated temperatures. Designs operating continuously near 71°C should prioritize the REC7.5-2405DRW/H2/A/M/CTRL for guaranteed performance.

Q: Do both parts meet the same compliance standards?

A: Both the REC7.5-2405DRW/H2/A/M/CTRL and DCW08B-05 are RoHS3 compliant, carry MSL 1 (unlimited) moisture sensitivity rating, and are REACH unaffected. Both share identical ECCN (EAR99) and HTSUS (8504.40.9580) classifications.

Q: Which part offers better efficiency?

A: The REC7.5-2405DRW/H2/A/M/CTRL delivers 82% efficiency compared to the DCW08B-05 at 78%. For power-sensitive applications or designs with thermal constraints, the REC7.5-2405DRW/H2/A/M/CTRL provides superior performance.
