ALD10F48-SL Equivalent & Substitute Parts

Part Overview

The ALD10F48-SL is an isolated module DC-DC converter manufactured by ARTESYN / Advanced Energy, part of the ALD15 series. This component provides a single 3.3V output at 10A maximum current from a 36V to 75V input range, delivering 35W of power. The device features remote on/off control, output current protection (OCP), over-temperature protection (OTP), over-voltage protection (OVP), and under-voltage lockout (UVLO) functionality.

The ALD10F48-SL is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing system maintenance, design updates, and procurement continuity for applications requiring isolated DC-DC conversion in commercial ITE environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ALD10F48-SL is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Input voltage range: 36V – 75V (must match or encompass this range)
• Output voltage: 3.3V (exact match required)
• Isolation voltage: 1.5 kV minimum
• Operating temperature range: -40°C to 85°C minimum

Mechanical Compatibility Requirements:

• Package type: 1/16 Brick form factor
• Mounting compatibility with existing PCB layouts
• Physical dimensions within acceptable tolerance for board integration

Functional Requirements:

• Single isolated output configuration
• Isolated module topology
• Commercial ITE application suitability

The AVD50B-48S3V3-6L meets the core electrical and functional requirements for substitution. However, differences in output current capacity, power rating, mounting type, and package configuration must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The AVD50B-48S3V3-6L is an active product from the same manufacturer with matching input and output voltage specifications. This substitute provides higher output current capacity (15A versus 10A) and increased power rating (50W versus 35W), making it suitable for applications requiring equal or greater power delivery.

Key Considerations:

1. Mounting Type Difference: The ALD10F48-SL uses surface mount (SMD) technology, while the AVD50B-48S3V3-6L uses through-hole (DIP) mounting. PCB redesign is required for mechanical and electrical integration.

2. Package Configuration: Both components use 1/16 Brick form factor with similar footprint dimensions (33.0mm × 22.9mm). Height difference is minimal (0.34" versus 0.37"), presenting no significant clearance issues.

3. Product Status: The substitute is an active product with current manufacturing support, ensuring long-term availability and supply chain stability compared to the obsolete ALD10F48-SL.

4. Compliance: The AVD50B-48S3V3-6L carries RoHS Compliance certification and REACH Unaffected status, meeting modern regulatory requirements.

5. Performance Margin: The higher current and power ratings of the substitute provide design margin for thermal management and load transient response.

Frequently Asked Questions (FAQ)

Q: Can the AVD50B-48S3V3-6L directly replace the ALD10F48-SL without PCB modification?

A: No. The mounting type differs (surface mount versus through-hole). PCB redesign is required to accommodate the different pin configuration and mounting method. However, the 1/16 Brick form factor and similar dimensions minimize layout changes.

Q: What are the electrical compatibility requirements for substitution?

A: The substitute must provide 3.3V output from a 36V to 75V input range with isolation voltage of at least 1.5 kV. The AVD50B-48S3V3-6L meets these requirements. Operating temperature range compatibility (-40°C to 85°C) must be verified for the specific application environment.

Q: Does the higher output current rating (15A versus 10A) affect system design?

A: The higher current capacity is a design advantage, not a limitation. Systems designed for 10A operation will function correctly with the 15A-rated substitute. Thermal management and power dissipation characteristics may improve due to the higher efficiency rating (91% versus 90%).

Q: Are there protection features differences between the two parts?

A: The ALD10F48-SL specifies remote on/off, OCP, OTP, OVP, and UVLO features. The AVD50B-48S3V3-6L lists only remote on/off and enable control (active low). Detailed protection feature specifications for the substitute should be confirmed with the manufacturer datasheet.

Q: What is the significance of the MSL (Moisture Sensitivity Level) difference?

A: The ALD10F48-SL has MSL 1 (unlimited shelf life without moisture control). The AVD50B-48S3V3-6L has MSL 3 (168-hour limit). This affects storage and handling procedures. MSL 3 components require controlled storage conditions and have a limited floor life after moisture barrier bag opening.

Q: Is the substitute suitable for the same commercial ITE applications?

A: Yes. Both components are specified for commercial ITE applications. The substitute's active product status and higher power rating make it suitable for equivalent or upgraded system designs in this application category.
