DAS50F05 Equivalent & Substitute Parts

Part Overview

The DAS50F05 is an isolated PoE module DC-DC converter manufactured by Cosel USA, Inc., designed to convert high-voltage input (88V to 370V) to a regulated 5V output at 10A maximum current, delivering 50W of power. This component is classified as obsolete, indicating that direct procurement may become unavailable. Identifying equivalent and substitute parts ensures design continuity and supply chain reliability for applications requiring isolated DC-DC conversion in commercial ITE environments.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAS50F05 are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Output voltage: 5V (fixed requirement)
• Maximum output current: 10A (fixed requirement)
• Power rating: 50W (fixed requirement)
• Number of outputs: 1 (fixed requirement)
• Mounting type: Through Hole (fixed requirement)
• Manufacturer: Cosel USA, Inc. (same manufacturer family)
• Product type: Isolated DC-DC converter module

Variable Parameters Defining Substitution Groups:

• Input voltage range (determines application suitability)
• Package type (12-DIP vs. 6-DIP affects PCB layout)
• Operating temperature range
• Efficiency rating
• Product status (Active vs. Obsolete)

The DAS50F05 input range of 88V–370V encompasses both the DHS50A05 (60V–160V) and DHS50B05 (200V–400V) input ranges. Substitution requires matching the input voltage requirements of the target application.

Parameter Comparison

Engineering Selection Recommendations

For DHS50A05 Substitution: The DHS50A05 is suitable for applications where the input voltage range is 60V–160V. This part is currently in active production status, ensuring long-term availability. The DHS50A05 provides an extended operating temperature range (-40°C to 100°C) compared to the DAS50F05 (-10°C to 85°C) and achieves higher efficiency at 84%. The 6-DIP package is significantly smaller than the 12-DIP package of the DAS50F05, requiring PCB layout modification. ROHS3 compliance provides enhanced environmental certification. Selection of this part is appropriate when the application input voltage does not exceed 160V.

For DHS50B05 Substitution: The DHS50B05 is suitable for applications where the input voltage range is 200V–400V. This part is currently in active production status. The DHS50B05 includes integrated protection features (Remote On/Off, OCP, OTP, OVP) and specifies 3 kV isolation voltage, providing enhanced system protection. The 6-DIP package requires PCB layout modification. ROHS3 compliance is provided. Selection of this part is appropriate when the application input voltage is 200V or higher and protection features are required or beneficial.

General Considerations: Both substitute parts are manufactured by the same supplier (Cosel USA, Inc.) and maintain electrical compatibility with the DAS50F05 in terms of output specifications (5V, 10A, 50W). The primary selection criterion is input voltage range matching. Package size differences necessitate PCB redesign. Both substitutes offer active product status, ensuring supply chain continuity beyond the obsolete DAS50F05.

Frequently Asked Questions (FAQ)

Q: Can the DHS50A05 replace the DAS50F05 in all applications? A: The DHS50A05 can replace the DAS50F05 only in applications where the input voltage does not exceed 160V. The DAS50F05 accepts input voltages up to 370V, while the DHS50A05 maximum input is 160V. If your application requires input voltages above 160V, the DHS50A05 is not suitable.

Q: Can the DHS50B05 replace the DAS50F05 in all applications? A: The DHS50B05 can replace the DAS50F05 only in applications where the input voltage is 200V or higher. The DHS50B05 minimum input voltage is 200V, while the DAS50F05 accepts input voltages as low as 88V. If your application requires input voltages below 200V, the DHS50B05 is not suitable.

Q: What is the impact of the package size difference between 12-DIP and 6-DIP? A: The DAS50F05 uses a 12-DIP package measuring 115.0mm × 58.0mm, while both substitute parts use a 6-DIP package measuring 58.4mm × 37.3mm. The substitute parts are significantly smaller. PCB layout and footprint modifications are required when substituting. Verify that the smaller package dimensions are compatible with your available PCB space.

Q: Are the substitute parts RoHS compliant? A: Yes. The DAS50F05 is RoHS Compliant. Both substitute parts (DHS50A05 and DHS50B05) are ROHS3 Compliant, which represents an enhanced environmental certification standard.

Q: What is the difference in operating temperature range? A: The DAS50F05 operates from -10°C to 85°C. Both substitute parts (DHS50A05 and DHS50B05) operate from -40°C to 100°C, providing a wider temperature range. If your application requires operation below -10°C or above 85°C, the substitute parts offer extended capability.

Q: Does the DHS50B05 include protection features that the DAS50F05 does not? A: The DHS50B05 includes Remote On/Off, OCP (Over-Current Protection), OTP (Over-Temperature Protection), and OVP (Over-Voltage Protection) features. The DAS50F05 does not specify these protection features. The DHS50A05 also does not specify these features. If your application requires integrated protection, the DHS50B05 is the appropriate choice.

Q: What is the isolation voltage specification? A: The DAS50F05 and DHS50A05 do not specify isolation voltage. The DHS50B05 specifies 3 kV isolation voltage. If your application requires a specified isolation voltage rating, the DHS50B05 is the only option among these three parts.

Q: How do efficiency ratings compare? A: The DAS50F05 has 82% efficiency. The DHS50A05 has 84% efficiency (higher). The DHS50B05 has 80% efficiency (lower). For applications where power dissipation and thermal management are critical, the DHS50A05 offers the best efficiency performance.
